Title: Minutely feeding apparatus
Inventor: HONDA TOSHIMASA
IPC: B23Q1/72
Filed: 1984-11-06
Abstract: PURPOSE:To permit the minute feed of a cutting tool or a grindstone which is used in fine work with high precision by reducing the reaction force acting onto the driving source side due to the deflection of leaf springs in a reaction- force adjusting part, thus eliminating the unevenness of feed by the driving source. CONSTITUTION:When a pulse motor 15 is driven by a feeding drive source 18, said revolution is transmitted to a ball screw 17, decelerated by a reduction gear 16, and a screw shaft 171 is projected. Then, a working body 13 is pressed by the top edge of the screw shaft 171, and shifted rightward with the rightward deflection of the leaf springs 121 and 122. Further, also a cutting tool 14 installed onto the transfer body 13 is shifted rightward, and cutting-in work is carried-out. In this case, the force corresponding to the reaction force provided onto the screw shaft 171 side of the ball screw 17 in proportion to the deflection amount of each spring 121, 122 is applied onto a reaction-force adjusting part 19 through wires 221 and 222. Therefore, each reaction force of the springs 121 and 122 is offset, and the cutting tool 14 can be minutely fed uniformly with high precision.

Title: High temperature slide valve
Inventor: ISOYAMA MITSUNORI
IPC: F16K3/314
Filed: 1989-09-07
Abstract: PURPOSE:To maintain control accuracy over a long period by providing a ceramic layer on the flat surface and top end surface on the upper stream side in the top end part of a valve body. CONSTITUTION:A valve body 4 is protruded and recessed by the operation of a valve stick 9, and the passage in a valve seat 3 is extended and contracted to control the flow rate of a controlled fluid 1 (high temperature fluid containing granules). At this time, the controlled fluid 1 in the inner part of a valve box 2 flows along the surface of the valve body 4 in the vicinity of the valve body 4. Therefore, the granules contained in the controlled fluid 1 are rubbed onto the surface of the valve body 4, whereby the surface of the valve body 4 is worn away, and the abrasive action often strongly acts in the top end part of the valve body 4. However, as the top end part of the valve body 4 is ensured the wear resistance to the controlled fluid 1 by ceramic plates 14, the suppression of abrasion in the top end part of the valve body 4 enhances the extension of life of the valve body 4, and the control accuracy to the controlled body 1 is maintained over a long period.

Abstract: PURPOSE:To execute the cold forging of internal gear helical tooth profile parts with good precision by forming a land part projecting to the inner circum ferential side on a die, forming the tooth profile of a mandrel tooth profile formed part to the helical tooth profile, supporting the mandrel in a movable manner in the axial direction of the mandrel, and in a rotatable manner around the axial center of the mandrel. CONSTITUTION:A stock 8 is pushed into a forming space by a sleeve punch 4, pulled to the inner circumferential side by a land part 2b of a die 2, and bitten into a tooth profile forming part 1a of a mandrel 1. The mandrel 1 is movable in the axial and rotational direction, and the tooth profile is formed in the stock 1 while the load is applied on the tooth of the mandrel 1 from both tooth surfaces. Thus, compared with the case where the load is mainly applied only from the upper tooth surface, no excessive bending stresses are generated at the tooth profile part of the mandrel 1, preventing the mandrel 1 from being broken. The tooth profile part to be formed is constantly restricted to the tooth profile part of the mandrel 1, and the precision of the tooth profile can be improved.

Filed: 1994-09-29
Abstract: PURPOSE: To suppress the increase of the power consumption of a measurement device in the case of measuring a signal delay difference from a subscriber's equipment to an intra-station equipment in a PDS(passive double star) transmission system. CONSTITUTION: Transmission line clocks (a) are frequency divided into (n) and counted and the counted output is latched for each input of a transmission reference timing (b) in a first latch circuit 3. Then, a second latch circuit 4 latches it for each input of a reception timing (c) and the difference of the respective outputs of the first and second latch circuits 3 and 4 is obtained in a subtraction circuit 8. An addition circuit 9 multiplies the difference by (n) adds it and digitized synchronization information (e) for indicating the head position of reception data (d) and outputs it as a delay measured result (f). As a result, since the transmission line clocks of a high frequency are not directly counted, the increase of the power consumption of a device is suppressed and an accurate measured result is obtained.
