IPC: H03B5/32
Filed: 1979-12-31
Abstract: PURPOSE:To reduce the frequency fluctuation caused by the temperature, by providing the temperature-sensitive resistance in series to a quartz oscillator. CONSTITUTION:The resonance frequency of the quartz oscillator 1 varies by the resonance current. Thus the frequency reduces when the resonance current becomes small. In this connection, a temperature-sensitive element such as the posistor 3 is connected in series to the oscillator 1. As a result, the resonance current is controlled to give a temperature compensation to the oscillation frequency. The posistor 3 can be attached easily to the oscillator 1 itself by the vapor deposition, baking or other methods.

IPC: F16F1/10
Filed: 1979-12-31
Abstract: PURPOSE:To improve a seat reclining mechanism in operating feeling by making the cross-sectional size and shape of a portion of a spiral spring, over a given length from its outer end, differ from the other portions in order to minimize the hysteresis of the torque characteristics. CONSTITUTION:Over the quarter or half of a coil of a spiral spring 10 from its outer end, the size and shape of the cross-section perpendicular to the longitudinal direction are defined as shown in the figure in order to improve its flexural rigidity so that the second moment of area is raised and the amount of eccentricity is reduced. At operation, the whole coil turns of the spiral spring 10 are almost uniformly bent, so that there are fewer contacts betwen plates and hysteresis becomes smaller. Thereby, the operating feeling of a seat reclining mechanism is improved and at the same time the spiral spring 10 can be made more compact.
