Abstract: PURPOSE:To avoid a poor discharge through preventing heating at a slide- contact portion by providing an impeller fitted to an armature shaft inside a pump-chamber which is partitioned off by a casing and an end-cover, and forming at an end-cover pump wall an annular projection portion slide-contacting the impeller. CONSTITUTION:Inside a pump-chamber 3 partitioned off by a casing 9 and an end-cover 15, an impeller 6 is fitted to an armature shaft 5 which protrudes out of a motor portion 4, and a wind-washer solution is sucked in from the suction-port 2 of a wind-washer tank 20, and exhaust is made from a discharge port 9a. At the pump wall 15a of the end-cover 15 is formed an annular projection portion 15c slide-contacting the impeller 6, and when a pump is operated, the lower part of the impeller 6 is slide-contacted to the annular projection portion 15c.

Title: Positioning circuit for magnetic head
Inventor: TAKI YOICHIRO
IPC: H02P25/06
Filed: 1987-11-24
Abstract: PURPOSE:To reduce sounds generated for seek by limiting the variation of the output signal of a summing amplifier by a limit circuit to output the signal. CONSTITUTION:A limit circuit 10 is added between a summing amplifier 5 and a power amplifier 12. Though a summing amplifier output signal 6 quickly rises up to a positive maximum voltage in the acceleration area at the time of forward movement, a limit circuit 11 does not quickly rise but gradually rises because an gradually increasing integrator output signal is connected to the cathode side of a diode. The change of the summing amplifier output signal 6 is limited by the limit circuit 11 in this manner to gently raise the generated force of a voice coil motor. Thus, the oscillation sound generated at the time of seek operation is reduced.
