Inventor: KINUTA NORIHIKO
IPC: B41J13/00
Filed: 1988-06-17
Abstract: PURPOSE:To enable a sure reading and copying to be conducted through the dissolution of a skew delivery and a transport speed change, when the push-pressing force of a copying device is insufficient, by providing a control arm which relieves the meshing state of a tooth row whose purpose is to transmit the rotational power of a handle to transport rollers. CONSTITUTION:A recording portion 2 is fixed on a base, and a recording paper sheet is supplied to a transport roller 236 at the lower part of a thermal head, and then, an appropriate push-pressing force is made to act on the recording portion 2 as a lead/light button is being pushed simultaneously with the rotation of a handle 238, and the recording paper sheet is push-pressed against the transport roller 236 by means of the thermal head, and copying is conducted. In the case of this push-pressing force being insufficient, a rotational power transmission gear 240 fitted at a control arm 241 is put in a turning movement in a direction breaking away from a position where it meshes with the gear 236a of the transport roller 236, by the energizing force of an energizing means. As a result, the connection between the transport roller 236 and 237 is cut off, and the rotational power of the handle 238 is not transmitted to the transport roller 236, and no recording is conducted.

IPC: A61F2/60
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To provide a device for a lower extremity prosthesis that allows walking in a good form on a frontal face, without making the user of the lower extremity prosthesis feel discomfort, by allowing the user to rest his or her upper body on the lower extremity prosthesis during the standing phase of the lower extremity prosthesis. SOLUTION: When a heel is grounded and a user's weight starts to apply to a device, an outer connecting member 40 and an inner connecting member 60 start to rotate downward from inside to outside, so that an upper mounting base 20 starts to be displaced outward and inclined inwardly downwards and a socket 3 also starts to be displaced outward and rotated outward. Thereby the user' body above his or her pelvis is started to move horizontally onto a lower extremity prosthesis 1. At the middle stage of the standing process of the lower extremity prosthesis 1, the displacement is maximized and the user's pelvis and upper body move horizontally onto the lower extremity prosthesis 1. In a subsequent stepping process, the upper mounting base 20 is started to restore itself to its position prior to displacement and inclination by the restoring force of a rubber damper 70 and restores itself to its position prior to displacement when the tip of the toe leaves the floor.

Title: High-purity graphite member for pulling up single crystal and its production
Inventor: ARAHORI TADAHISA
IPC: C30B29/06
Filed: 1995-06-15
Abstract: PURPOSE: To easily obtain a high-purity graphite member which is less contaminated by impurities and from which the production of a silicon single crystal having high quality is possible without requiring a special equipment by subjecting the graphite member to be purified to a heat treatment in a specific reduced pressure range and temp. region. CONSTITUTION: The desired graphite member is obtd. by heat treating the graphite member to be purified in the temp. region of 1500 to 2500 deg.C under the reduced pressure of 10<-1> to 10<-6> Torr. This graphite member is the high- purity graphite member for pulling up the single crystal having a metal impurity content of >=1ppm. The reason why the metal impurity content is confined to 1ppm lines in that if this content exceeds 1app the purification of the graphite member is insufficient and the silicon single crystal having the required high quality (high purity) is not obtainable with the device for pulling up using the graphite products consisting of such member. The metal impurities, such as Fe, Ni, Cr, Cu and Na, in the graphite member which are considered harmful for semiconductors are evaporated by this treatment and are removed from a purification treating furnace by a vacuum pump, etc.
