Title: Power steering gear for ridden-type agricultural machine
Inventor: SAKAI SEIJI
IPC: A01C11/02
Filed: 1984-05-28
Abstract: PURPOSE:To enable the appropriate operation of a steering wheel for either rapid straight movement or slow turning movement, by changing the ratio of rotational frequency of a transmission mechanism for the pump input shaft of a power steering gear to that of an engine, depending on the working condition of a working section. CONSTITUTION:Since no tension is applied to a control wire 27 as a plating transmission section 8 slides on the surface of a paddy filed, a tension roller 23a is brought into contact with the belt of a tension pulley transmission mechanism 23 by a spring unit 28 so that the power pump 18 of a power steering gear 14 receives motive power from an engine through the transmission mechanism and is thereby driven at a low ratio of rotational frequency to that of the engine. At the time of turning on a protrusion of ground, backing up or the like, the lever 26 of a vertically moving linkage 2 is put in action to make the control wire 27 tense. As a result, a rocker arm 25 swings to bring a tension roller 24a into contact with the belt of a tension pulley transmission mechanism 24 to drive the pump 18 at a low ratio of rotational frequency to that of the engine.

Abstract: PROBLEM TO BE SOLVED: To obtain an atomic force microscope by which both a part, to be measured, in a sample and a cantilever-type detection part (a cantilever) can be observed simultaneously at a proper resolution by a method wherein a diaphragm is installed at the optical system of a magnifying imaging device. SOLUTION: In an atomic force microscope, knobs 61, 62 are operated and a moving frame 5 is moved to the horizontal direction while the magnified image of a cantilever 1 and that of a sample S are being observed by a magnifying imaging device 7. Thereby, since the contilever 1 and an optical system 2 are moved to the horizontal direction with reference to the sample S, a desired part in the sample S can be aligned with the tip part of the contilever 1. At this time, a diaphragm is installed at the magnifying imaging device 7, a numerical aperture is set to a small value, and a depth of field is made large. As a result, both the image of the cantilever 1 and that of the sample S are shown at a comparatively good resolution. Consequently, an operator can simultaneously grasp the shape or the like of the contilever 1 and that of the sample S precisely, and a part to be measured can be positioned easily.

Title: Cache management method for decentralized file system
Inventor: NAKANO HIROHIKO
IPC: G06F12/00
Filed: 1994-05-25
Abstract: PURPOSE:To provide a cache management method for a decentralized file system to effectively assure the latest properties of a cache. CONSTITUTION:A client caches the files for every block (404) and defines the state of the cashed block as the 1st state (416). When a file is updated by another client, the state of the block belonging to the updated file is changed to the 20d state (406). When an access is applied to the block of the 2nd state (418), an inquiry is given to the corresponding file server about the latest properties of the block (408). If the block is not latest, this block is cached again. Therefore, the latest properties can always be assured for the block of the 1st state. Thus, it is not required to give an inquiry to a file server about the latest properties of the corresponding block before an access is applied to this block.
