Title: Clutch engaging/disengaging device
Inventor: YAMAMOTO YASUSHI
IPC: B60K20/02
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent a start of clutch automatic disengagement just after gear-in by erroneous shift operation by stopping a start of the clutch automatic disengagement even if specific conditions are realized when judging that a clutch exists on the disengaging side more than a half clutch region by detecting a clutch stroke. SOLUTION: Whether or not a clutch exists on the engaging side more than a half clutch region is judged from output of a clutch stroke sensor (132). When output voltage is larger than a neutral learning value, it is judged as the disengaging side, and is regarded as erroneous operation. While, when it is not ON by the knob switch rear side in a front gear position in the case of the engaging side, it is regarded as existing no shift intension (133, 134, 137). And, when it is ON by the knob switch rear side in a rear gear position, it is regarded as erroneous operation, so that a start of clutch automatic disengagement is stopped in both cases (133, 135, 137). Even if two conditions of gear-in and ON of a knob switch on the gear-out side are realized, a start of the clutch automatic disengagement by erroneous operation can be prevented.

Title: Induction heating rice cooker
Inventor: KAMISAKI MASAYOSHI
IPC: A47J27/00
Filed: 1992-11-20
Abstract: PURPOSE:To miniaturize a radiator and a ventilation fan and to reduce the cost of the rice cooker by leading heating of a high frequency current generating means to a high frequency magnetic field preventing/reflecting plate, and radiating heat into the air from the reflecting plate. CONSTITUTION:A reflecting plate 7 operates as magnetic shielding parts which can obstruct a fact that a line of magnetic force generated from an induction heating coil 3 goes out outside a main body 1. A radiator 6 and a reflecting plate 7 are allowed to fit closely and coupled to each other with a screw, therefore, heating from a power element constituting a high frequency current generating means 4 passes through the radiator 6 and reaches the reflecting plate 7. Accordingly, this heating is diffused into the air from both of the radiator 6 and the reflecting plate 7 and cooled by ventilation air of a ventilation fan 5. Both of the radiator 6 and the reflecting plate 7 can be used for heat radiation, and a heat transfer area can be increased remarkably compared with a conventional one using only the radiator 6. As a result the radiator 6 can be miniaturized, or the ventilation fan 5 be made to be a low output one and miniaturized. In such a way, the induction heating rice cooker which is miniature as a whole and is low in its cost can be realized.
