IPC: A47J37/00
Filed: 1989-06-30
Abstract: PURPOSE:To automatically bake satisfactory bread by detecting gas concentration generated from a bread material, and controlling the baking time in accordance with the quantity of bread. CONSTITUTION:A control part 25 brings the lower heater 3, a motor 11, a fan heater 43, a fan motor 47 and a chopper to driving control, based on a result of detection from a gas detecting means 23 and a temperature detecting means 27. In a baking process after molding and fermentation, a state deciding part 29 starts to bake in a state that a temperature of the lower heater 3 is maintained and controlled at a prescribed baking temperature. Immediately after the start, gas concentration drops once, therefore, a first minimum value VA at this time is derived. Thereafter, the state deciding part 29 starts to drive the fan heater 43 and the fan motor 47 and detects gas concentration VB (maximum value) in a container 1 at that time. Thereafter, the gas concentration drops again, therefore, a second minimum value VC at this time is derived. The state deciding part 29 calculates a difference of both of them, and when it exceeds a set value Vx, the baking time is set to 60 minutes, and when it does not exceed, the baking time is adjusted to 65 minutes, and the subsequent baking is brought to continuous control.

Title: Synchronizing circuit of carrier wave
Inventor: ISHIHARA TOSHIO
IPC: H03L7/12
Filed: 1982-09-24
Abstract: PURPOSE:To hold a synchronous phase with a simple circuit configuration, by applying a false input signal from an AC signal generating part to an automatic phase controlling part as an AC signal when an input signal is defective. CONSTITUTION:The output of a phase detecting part 1 is applied to an LPF2 and a signal detecting part 5. When a discriminated result is normal, the output of the detecting part 5 is applied to an AC signal controlling part 7 to inhibit an AC signal outputted from an AC signal generating part 8 from being applied to an adding part 6. When the output of the detecting part 1 is lower than a reference level, the detecting part 5 discriminates that the state is abnormal and the controlling part 7 applies the AC signal from the generating part 8 to the adding part 6 as a false input signal. Consequently, an output from the automatic phase controlling part 3 is applied to a voltage control oscillating part 4. The output of the controlling part is approximately proportional only to the DC component of the output signal from the generating part 8, so that the oscillating part 4 can oscillate at the frequency close to the central frequency of the input signal.

Title: Device for operating switch board
Inventor: SEYA SEIICHI
IPC: F16H57/12
Filed: 1981-10-21
Abstract: PURPOSE:To prevent generation of abnormal sound and simultaneously improve the accuracy of the ignition timing by mounting a pinion and an elastic member movable in the axial direction on a switch board shaft and supporting either one of both members on the fixed end surface side. CONSTITUTION:When the pinion 20 is operated by a force F due to an engine side gear 22, a component f1 of force rectangular to the tooth surface is generated. On the other hand, when an axial load Q due to a spring 30 operates, a component q1 of force confronting the component f1 of force is generated. By the rotational operation of the pinion, a gap G1 is formed, and the tooth surface is pressed only in direction at the rear surface thereof in a state where a gap g is formed, at the gear enmeshing portion, thus the gear is operated. Therefore, even when any rotational variation is generated in the engine, since the pinion 20 follows after the engine side gear 22, and simultaneously the shaft 14 has a rotational resistance due to the spring 30, it is possible to prevent the impact sound at the enmeshing part and the vibration of the shaft 14. Thus, the ignition timing becomes appropriate.

Abstract: PURPOSE:To avert ground stains effectively by grounding a conductive substrate of a photoreceptor in primary charging, and grounding the conductive substrate through a capacitor in secondary charging and up to a developing process after this. CONSTITUTION:In subjecting a photoreceptor 1 to primary charging, a conductive substrate 1A is grounded by closing a switch SW as shown in figure (I). Next, to subject the same to secondary charging, the switch SW is opened to ground the substrate 1A through a capacitor C. Thence, the photoreceptor is exposed by the light images of an original O, and at this time, too, the switch SW is held open. Thereupon, if it is developed while maintaining its surface potential at 0 by regulating the capacity or the like of the capacity C in such a way as to offset the charging potential of an intermediate layer 1C by the charging potential in the capacitor C, the sticking of the toner is effectively prevented and ground staining is prevented.
