Abstract: PURPOSE:To simplify circuit constitution of a C-MOS quartz oscillating circuit and to reduce its power consumption, and to stabilize oscillation frequency against variations in power voltage, by adding a constant current circuit to the C-MOS quartz  oscillating circuit. CONSTITUTION:A current Is generated through the oscillating operation of a C- MOS oscillating circuit 10 is equal to K5 (VGSQ5-VTNQ5)<2>, where K5 is the design constant of an MOS trasistor (TR) Q5, VGAQ5 is the gate-source voltage of the TRQ5, and VTNQ5 is the threshold voltage of the TRQ5. The current Is, therefore, contains no component of a power voltage VDD and, even if VDD has a drift, no influence is affected to it. Further, the VGSQ5 is a constant component determined by  the process of the TR and it is made constant by a reference voltage generating circuit 11a to make the current Is constant. Therefore, the Is can be regulated to a  constant current through the Q5 and the power consumption of the circuit is reduced.

IPC: B66B1/06
Filed: 1994-06-14
Abstract: PURPOSE:To improve conveniences for use by providing a parking switch on a plurality of floors for connection in series, and connecting a plurality of poles in series among switches. CONSTITUTION:In the case of a three-story building, for example, a parking switch A (on the first floor) is changed over to A2 for keeping an elevator at rest and, then, a user walks up to the third floor via a staircase. When he/she desires to go onboard the elevator from the third floor, a parking switch B (on the third floor) is changed over to B2, thereby keeping the elevator in operating state. When it is desired to lower the elevator to the first floor and, then, keep the elevator at rest, the parking switch A is changed over to A1. As a result, the elevator turns into stopped state. Thus, the elevator can be freely kept in operating or stopped state by operating the parking switches A and B on each floor, and conveniences for use can be thereby improved.

IPC: B65H29/12
Filed: 1985-06-19
Abstract: PURPOSE:To reduce the extent of load at the time of belt running, by making rigidity in a belt somewhat smaller, while letting the belt extend freely by dint of frictional force between belts to be produced at a bending part, and preventing slippage lying between these belts from occurring. CONSTITUTION:A belt 1 is rolled on rollers 2, 3 and 4, while the roller 2 is driven in an arrow direction but remaining rollers 3 and 4 are supported free of rotation. A belt 5 is rolled on rollers 6, 7 and 8 while it comes into contact with the belt 1 face-to-face. The roller 6 is driven in an arrow direction but remaining rollers 7 and 8 are supported free of rotation. The belt 1 is high in rigidity but the belt 5 is low so that it is sufficiently deformed by frictional force due to contact with the belt 1 rolled on the roller 3. When both these belts 1 and 5 run at equal velocity with rotation of both rollers 2 and 6, the belt 5 extends so as not to cause any slippage at a contact part between them.
