The present technology provides a method of manufacturing a pneumatic tire. The method of manufacturing a pneumatic tire uses a laminated sheet having a predetermined length and an inner liner layer formed from the laminated sheet through a step of cure-molding the tire with end portions of the laminated sheet lap-spliced. In the method, when at least the sheet made of thermoplastic resin or a thermoplastic resin composition obtained by blending the thermoplastic resin and the elastomer is cut into the predetermined length, the cutting is performed by using an edge tool having a non-sharp edge under a temperature condition not lower than 60 C. and not higher than a melting point of the thermoplastic resin.

A glass plate separating apparatus, as one example, includes: a trigger device that forms a start point flaw in a first main surface of a glass ribbon on a division-planned line; a pair of holding members disposed at the first main surface side of the glass ribbon; and a heater disposed at a second main surface side of the glass ribbon. The pair of holding members, each of which extends parallel to the division-planned line, is brought into contact with the glass ribbon at both sides of the division-planned line while being lowered together with the glass ribbon. The heater extends along the division-planned line, and is brought into contact with and pressed onto the glass ribbon on the division-planned line while being lowered together with the glass ribbon.

A heat chamfering apparatus includes a heated body configured to peel an edge of a glass panel by applying thermal shock to the glass panel while being in contact with the edge of the glass panel and a heater heating the heated body. The heated body includes a heated region and a contact region in a longitudinal direction thereof, the heated region being heated by the heater, and the contact region being configured to be in contact with the glass panel. The cross-sectional area of the contact region is smaller than the cross-sectional area of the contact region. A heat chamfering method includes peeling an edge of a glass panel by applying thermal shock to the edge of the glass panel by moving a heated body heated by a heater relatively with respect to the glass panel along and in contact with the edge of the glass panel.

A heat chamfering apparatus. A support unit supports a glass panel. A heat chamfering unit heat-chamfers an edge of the glass panel by applying thermal shock thereto. The support unit includes a contact support portion supporting the glass panel while in contact with the glass panel and a base portion configured to support the contact support portion. The contact support portion is formed from a first material. The base portion is formed from a second material. The first material has a smaller change in temperature due to lower thermal conductivity and a smaller change in size at high temperature due to a smaller coefficient of thermal expansion while being more ductile due to lower hardness, compared to the second material. In a heat chamfering method, a glass panel is located on a support unit, and an edge of the glass panel is heat-chamfered by applying thermal shock thereto.

This application relates to an amplifier selectively operable in first or second modes. The first mode is a BTL mode with first and second output drivers (103p, 103n) both active to generate respective driving signals that vary with an input signal. The second mode is an SE mode, where the first output driver (103p) is active to generate a driving signal at and the output of the second driver (103n) is held constant. A controller (201) selectively controls the mode based on an indication of output signal amplitude. In the first mode, a ratio of magnitude of the two driving signals varies with the indication of output signal amplitude, i.e. the magnitudes of the two driving signals may vary so as to be not equal.

A weight release device capable of being operated in deep sea without accompanying a mechanical operation. The weight release device includes a housing fixed to the underwater observation device; a thread made of thermoplastic resin; electric heater portions; a weight support plate; a locking member of the thread made of the thermoplastic resin; and a ring for hanging the weight. The thread made of the thermoplastic resin is arranged from a start point housed in the housing, arranged to pass through the first electric heater portion, locked to the locking member of the thread made of the thermoplastic resin, arranged to pass through the second electric heater portion housed in the housing, and returned to an end point housed in the housing. The weight is released only by conducting an electricity through the electric heater portion to release the weight for floating the underwater observation device.
