Inventor: MIYAZAKI KENJI
IPC: F16C13/02
Filed: 1994-02-22
Abstract: PURPOSE:To surely prevent lubricating oil in a bearing part to which the lubricating oil is always supplied such as the roll shaft of a rolling machine from leaking. CONSTITUTION:An oil thrower seal 5 and a secondary dewatering seal 4 are provided between the terminal part of an end retainer 1 and the rotary shaft of a rolling roll 10, and an oil thrower projection 14 to prevent the lubricating oil from flowing in the secondary dewatering seal 4 side is provided at the terminal part of an expansion control ring 15 mounted on the secondary dewatering seal 4. Therefore, the lubricating oil intruding the back plane side of the oil thrower seal 5 is shaken off by the oil thrower projection 14, and it is returned to an oil chamber 16 passing a return hole 13 formed on the end retainer 1. Therefore, it is possible to surely prevent the intrusion of the lubricating oil to the secondary dewatering seal 4 that is the cause of oil leakage from occurring.

Title: Semiconductor distortion sensor
Inventor: YOSHINO YOSHI
IPC: G01L9/00
Filed: 1993-03-09
Abstract: PURPOSE:To provide a highly accurate semiconductor distortion sensor by reducing the unevenness in lateral width of a distorting section due to uneven etching rate in trench formation. CONSTITUTION:Part of a substrate which originally exists in a trench 2a formed in a buried region 2 is removed by electrochemical etching to the boundary of the junction with an upper layer region 3 to form a distorting section A. The bottom end of the entire slope 1b of a trench 1a is formed in contact with the buried region 2, which is exposed at the bottom of the trench 1a. Even if over-etching is performed after the trench 1a have reached the junction boundary of the upper layer region 3 through the trench 2a in the buried region 2, the side etching of the semiconductor substrate 1 is associated with the exposure of the buried region 2. This makes uneven the lateral width of thick portions on the periphery of the distorting section A, and thus reduces the unevenness in sensitivity.

Title: Wireless controlling device for mobile agricultural machine
Inventor: MORI TAIICHI
IPC: G05D1/00
Filed: 1988-02-29
Abstract: PURPOSE:To improve the operability of an agricultural machine and perform sure remote control of the machine, by carrying out resetting operation by a signal transmitted from a transmitter when the level of the steering signal inputted into a receiver is lowered below a prescribed level and the steering control operation is interrupted. CONSTITUTION:The steering signal transmitted from a transmitter 1 is received by a receiver 3 to effect the remote steering control of a mobile vehicle 2. When the mobile vehicle 2 is positioned near the propagation limit of radio wave for the steering and when the level of steering signal inputted into the receiver 3 is detected to be lower than a prescribed level, the steering control is interrupted and the mobile vehicle 2 is stopped. Since the remote control can be continued in the case of temporary disturbance of radio wave or temporary voltage drop of a power source, the interruption of the steering control can be released to restart the steering control by transmitting a resetting signal from the transmitter 1.

Title: Recording and reproducing device of magnetic tape
Inventor: ARAKI SHIGERU
IPC: G11B20/18
Filed: 1982-03-26
Abstract: PURPOSE:To prevent the generation of a burst error, by recording double the sound informations adjacent to each other in terms of time of a digital TV signal on different 1st and 2nd tracks as well as the 3rd and 4th tracks and combining the error correction and the error alteration with high efficiency. CONSTITUTION:The data exactly same as tracks 1A.1B/2A.2B are written double on tracks 3A.3B/4A.4B. When a part of the information equivalent to the sub-block of 1A for exapmle is disturbed by a tape drop-out, the sub-block parity of the corresponding sub-block detects an error. Then the information of the error sub-block of the 1A is corrected with the information on the corresponding sub-block of the 3A to which the data is written double and on the basis of the error information. A correct correction is ensured if the corresponding sub-block of the 3A is not erroneous. In case the sub-block of the 1A has an error together with the corresponding sub-block of the 3A, the alteration of the error is carried out with the mean value of the sampling information of the primary interpolation, i.e., the before and after the trucks of different error sound informations.

Title: Signal head searching circuit
Inventor: TAKEUCHI TAKASHI
IPC: G11B20/10
Filed: 1983-03-25
Abstract: PURPOSE:To assure the head searching of a PCM signal at the time of sound recording/reproducing by using a signal tack pulse which is used for servo drive of a cylinder for helical scan head of a VTR. CONSTITUTION:At the time of recording, the vertical synchronizing signal is extracted from a signal input 15 and then divided to give the servo drive to a motor 5 with a reference signal of 30Hz. At the time of reproduction, the motor 5 receives the servo drive on the basis of the 30Hz output of an oscillator 13. In this case, the output 16 of the FF9 is always proportional to the revolution of a cylinder 4 at the time of both sound recording and reproducing. At the same time, a signal having a relative relation with a video recording pattern is obtained. The timing obtained by delaying the output 16 by a delay circuit 17 is applied to a head searching signal of a PCM signal. Then the PCM signal is recorded at the position obtained with a delay through the circuit 17. Thus the relative position can always be decided for the recording pattern with an input video signal.
