Title: High pressure selecting mechanism
Inventor: OGAWA KAZUNORI
IPC: F03C1/34
Filed: 1991-02-04
Abstract: PURPOSE:To make the high pressure selecting mechanism of a fluid pressure- operated motor compact and simple in structure by forming a pair of first recessed parts on the face brought into contact with an upstream side passage member and a second recessed part with a valve body built therein on the face brought into contact with a downstream side passage member, and providing a plate member for communicating these recessed parts mutually between the upstream and downstream side passage members. CONSTITUTION:Pressure oil is fed to one of oil passages 21, 22 from a hydraulic pump by the switching operation of a control valve and discharged from the other oil passage to rotate a hydraulic motor 20 in the specified direction. At this time, pressure oil is fed to a cylinder 24, a feed-discharge port 31 or 32 in a specified block communicated with one oil passage 21 or 22, and the pressure of a cylinder 24 and the feed-discharge port 32 or 31 in the other block communicated with the other oil passage 22 or 21 is released. The pressure oil therefore enters the recessed part 34 side, a ball 37 or 38 closes the other communicating passage 36 or 35, and the pressure oil enters into a high pressure selecting passage 33 so as to supply high pressure oil to the other hydraulically operated part.

IPC: G11B5/39
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To make performable a sure and quantitative check of a magneto- resistance effect head (reproducing head). SOLUTION: A constant current source 31 gives a check current ISc to a reproducing head 20 for the purpose of obtaining an output from the reproducing head 20.
