IPC: B25B21/00
Filed: 1995-04-14
Abstract: PURPOSE: To provide necessary torque for fastening and unfastening works of a screw by means of a small-sized air motor by setting reverse rotation maximum torque when the link inner pressure of a portable type compressor is air pressure in the specification, under normal rotation maximum torque when the link pressure is lowered. CONSTITUTION: A rotor 12 having grooves in which vanes 11 are slidably inserted in the radial direction is arranged in the cylinder 10 of an air motor 5. This cylinder 10 is provided with an exhaust port 15, an intake air port 13 for normal rotation, and an intake air port 14 for reverse rotation. An exhaust angle β = about 5 deg.-20 deg., and the exhaust port 15 is provided on the position nearer the intake air port 14 for reverse rotation than the intake air port 13 for normal rotation. By setting the exhaust angle βin this way, normal rotation torque at the air pressure in specification becomes larger than reverse rotation torque. However, the reverse torque at beginning unfastening mostly requiring torque for the unfastening work becomes nearly equal to the normal rotation torque at completing fastening mostly requiring torque for the fastening work.  Further, the air motor 5 can be miniaturized.

Title: Phase-synchronous oscillator
Inventor: OKINO TAKAYUKI
IPC: H03L7/085
Filed: 1980-06-30
Abstract: PURPOSE:To facilitate adjustments by simplifying a DA converter for the low-order bits. CONSTITUTION:The high-order digit bits 1-m of the output of a digital phase comparator 1 are DA-converted by a DA converter 4, and the low-order digit bits m+1-n by a DA converter 5. Analog outputs of the DA conversion are added together by an adding circuit 6, and the sum is applied to a voltage-controlled quartz oscillator VCXO3, whose oscillation frequency is controlled, so that the output signal of the VCXO3 phase-synchronizes with an input signal. As the DA converter 4, a high-precision DA converter of a ladder type, etc., is used, but it is only for the high-order digit bits, so the width of a stairecase-shaped step is large and adjustments for linear operation are easily. As the DA converter 5, on the other hand, a converter is used which varies the duty of pulses and converts them into an analog signal.

CONSTITUTION:In a group management device 10, if the up-peak time is detected by a means 10C from the calling generation situation and the number of waiting users on a standard floor, and cage which completes service is selected as a candidature cage for the calling back to the standard floor by a means 10D. Then, the arrival interval of the cage at an expected arrival time in the case where the candidature cage is called back to the standard floor is calculated by a means 10E, and the max. average arrival interval among the average arrival interval at each arrival time point of each cage which arrives afterwards is calculated by a means 10F. A means 10G compares the both time, and when the former is larger, the candidature cage is immediately called back to the standard floor, while if the latter is larger, the cage is put into waiting, and at the time point when the former becomes larger than the latter, the candidature cage is called back to the standard floor. Accordingly, the arrival interval of each cage to the standard floor can be set nearly uniform.
