Title: Optical switch
Inventor: TOJO MASAAKI
IPC: G02B26/02
Filed: 1985-07-08
Abstract: PURPOSE:To eliminate the need for a lens and easily align optical axes with each other and to simplify the constitution of an optical switch and to reduce its size by placing two optical fibers in a V groove and pressing them by a pressure plate. CONSTITUTION:The optical fibers 7 (7a and 7b) are placed in the V groove 8 of a fixation table 9 and pressed by the pressure plate to which springs 12 and 13 made of shape memory alloy are fitted. While the spring 13 shrinks and the spring 13 expands, the pressure plate 10 is pressed to align their optical axes with each other securely and when the spring 12 shrinks and the spring 13 expands, a pressure part 11 presses the intermediate part between the groove 8 and fixation part 9 and the fiber 7b flexes to have its tip separated from the groove, cutting off light. Therefore, no lens is required and the optical axes need not be adjusted, reducing the size of the structure.

Title: Temperature control device of heat fixation device
Inventor: TANIOKA HIROSHI
IPC: G03G15/20
Filed: 1982-08-27
Abstract: PURPOSE:To enable a thermal fuse settable in an optional position and to provide a simplified design and better prompt responsiveness by providing a heating element independently of a heat source and operating the thermal fuse with said element. CONSTITUTION:A thermal circuit 10 detects the surface temp. of a roll by the heat from a heater 4 with a thermistor 8 and outputs a heater driving signal to the transistor (TR)11 of a switching element in order to control the same constant. A relay coil 12 is operated by the TR11, the thermal fuse 9 is operated by the heating element 15 in parallel with the heater 4. Since a proportional relation is maintained between the calorific value of the heater 4 and the calorific value of the element 15, the fuse 9 can be operated by the element 15 in place of the heater 4. The need for the thermal fuse which is blown by the heating temp. itself of the heater 4 is thus eliminated, whereby the difficulty in the positional adjustment between the fixation roll and the thermal fuse is eliminated and the need for placing the fuse near the roll is eliminated.

IPC: B21B1/22
Filed: 1986-06-27
Abstract: PURPOSE:To prevent the generation of surface flaws by providing a specific relation between the heating temp. of a slab and the content of S in a heavy oil according to the content of N in the steel of a hot rolling material. CONSTITUTION:The heating temp. T( deg.K) of the slab and the content of S in the heavy oil to be used for heating the slab are so controlled as to satisfy the relation expressed by formula I according to the content of N in the steel at the time of hot rolling the continuously cast slab of an austenitic stainless steel. The reason thereof lies in that the cause for the generation of cracks is attributable to the heating temp. and the content of S in the heavy oil to affect grain boundary oxidation and that the content of N in the steel is presumed to promote the generated cracks. The generation of the surface flaws such as scabs is therefore, prevented if the heavy oil contg. S at the low ratio to satisfy formula I is used even if the content of, for example, N in the steel is as high as 0.15%.
