Title: Ball for ball bearing and manufacture thereof
Inventor: HIRAKAWA KIYOSHI
IPC: C21D6/00
Filed: 1993-03-08
Abstract: PURPOSE:To eliminate deterioration with the lapse of time of acoustic characteristics of a ball bearing by tempering the balls of the ball bearing which consists of a steel inner ring or a shaft, a steel outer ring, and multiple steel balls after surface hardening process. CONSTITUTION:Normal hardening is applied to the surface of a ball 8 which applied to the ball 8 at 125 deg.C for 120 minutes, and rough cutting is performed to the ball 8. The ball 8 is beaten against a plate to harden the surface of the ball 8. After the ball 8 is tempered at 160 deg.C for 120 minutes, following surface hardening process, final grinding is carried out to form a ball for ball bearing. It is thus possible to restrain the shape accuracy of a ball surface from being deteriorated with the passage of time, and the acoustic characteristics of the ball bearing 3 in which the balls 8 are mounted from being deteriorated. To exhibit the effect as much as possible, it is preferable to make the shape accuracy of the ball 8 3mumRms or less.

Abstract: PURPOSE:To utilize a voice terminal and low-speed no-voice terminal for communication through minimum operation by providing a circuit which switches and connects a high-speed channel to a partially divided channel and another circuit which switches and connects a low-speed terminal to a low-speed channel. CONSTITUTION:A switching circuit 8 switches a channel 11, used for LBS transmsission, for the LSB (least significant bit) transmission of a voice in original use mode or the transmission of no-voice data. A switching circuit 9 connects a signal from a low-speed no-voice terminal equipment 2 to an additional data channel 12 for control. When voice communication and low-speed no-voice communication are performed with the same party subscriber simultaneously, circuits 8 and 9 are switched to the side of a terminal (b) and a low-speed no-voice signal is transmitted as a substitute for LSB, thereby performing the simultaneous communication of a voice and low-speed no-voice data through only one channel of 64k bits/S. In other cases, the circuits 8 and 9 are switched to the side of a terminal (a) to transmit the low-speed no-voice signal via the channel 12 independently of the voice.

IPC: G06K9/62
Filed: 1989-03-27
Abstract: PURPOSE:To attain a feature recognition with high accuracy by making a relative distance between character boundaries into a coordinates variable and permitting it to be remarkably. CONSTITUTION:Respective components of vectors to be primary features PA1 and PA2 are moved, namely propagated by a unit quantity in prescribed directions for respective components, and next, when prescribed stop conditions are satisfied, the components of the vector are copied to a secondary feature PA3 storage circuit while distinguishing a stop position and a cumulative propagation frequency. The data in the secondary feature PA3 memory device obtained in such a manner can be described in a matrix having three coordinates variables. Provided that, among three coordinates variables, two are positional coordinates and the remaining one is the relative distance between the character boundaries, namely, the number of times of the cumulative propagation. In such a manner, by permitting the relative distance between the character boundaries, namely, the number of times of the cumulative propagation to be remarkably as the coordinates variable, the essential high-order feature quantity of the character can be extracted. Thus, the features PA1-PA3 can be recognized with high accuracy.
