Filed: 1981-10-13
Abstract: PURPOSE:To improve the durability of a sector gear, by fixing a pair of left and right sector gears at both sides of a vertical shaft at the back of a reflection mirror of an antenna and driving the sector gears around its horizontal shaft through anti-backlash. CONSTITUTION:A power amplifier 11a for drive supplies driving power for left and right motors 9a, 10a with the same rating, resulting in producing the same torque toward the arrow A. Further, motors 9b, 10b produce the same torque toward the arrow B with the driving power supplied from a power amplifier 11b for driving. Then, a synthesized torque between the motors 9a, 10a and 9b, 10b is exerted to sector gears 8a, 8b, and they are turned toward the arrow D when the torque for the motors 9a, 10a is larger and reversed when that of the motors 9b, 10b is larger. Thus, a reflection mirror 2 of the antenna 1 is vertically turned with the sector gear pair (8a, 8b), allowing to share out the weight load of the antenna 1 applied to the sector gears 8a and 8b and to improve the durability.

Filed: 1988-07-04
Abstract: PURPOSE:To enable to absorb easily the transformation by the thermal expansion by making a part of a microwave circuit movable. CONSTITUTION:The microwave power generated at a magnetron 10 is propagated to a circular coaxial wave guide 30 composed of an inner conductor 31 and an outer conductor 32 through a square wave guide 20 and three stab tuners 21. In a choke structure, a coaxial line is formed with the inner conductor and a cylinder 33 of the conductor. This coaxial line is folded back at the point of a quarter of the wave length from the terminal end and is connected to a coaxial line composed of the cylinder 33 and the cylinder 34 of the conductor. The poor contact between the inner conductor 31 and the cylinder 34 at the folding point scarcely gives an adverse effect, and for example the inner conductor 31 can freely move in the axial direction by having it contacted by a spring 35. As a result, the generation of abnormal transformation due to the thermal expansion caused by the plasma of the high temperature can be easily prevented and a device of high reliability can be realized.

Title: Minor short circuit detecting method for chargeable lithium battery and charging apparatus
Inventor: TOYOGUCHI YOSHINORI
IPC: H01M10/48
Filed: 1995-06-30
Abstract: PURPOSE: To previously detect inner short circuit which sometimes causes rupture and inflammation and prevent a serious accident beforehand by detecting disorder due to repeated increase and decrease of voltage of terminals at the time of charging while controlling current in a chargeable lithium battery. CONSTITUTION: In a chargeable lithium battery, at the time of charging while controlling current, minor short circuit is detected based on the disorder due to repeated increase and decrease of voltage of terminals with the elapse of time. Also, minor short circuit is detected based on the fact that the voltage of the terminals becomes lower than a previously set voltage within a previously set time. Moreover minor short circuit is detected based on the fact that the voltage of the terminals during charging becomes lower than the set voltage learned from the previous charging. After the danger due to the short circuit is detected in these manner, charging is stopped and at the same time a charging apparatus is provided with a lock function in order not to carry out charging until the battery is changed.
