Title: Handrail
Inventor: YOTSUMOTO TAKEHIKO
IPC: E04F11/18
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To improve the safety by providing a grip bar on which a rugged surface of a lattice pattern is formed on an outer circumferential surface of a synthetic resin covered layer provided on the circumference of a metallic pipe. SOLUTION: A handrail comprises a pair of holders 1 to be fixed to a wall, and a grip bar 2 to be held by the holders 1. The bar 2 comprises a synthetic resin inner skin layer to cover the outer circumferential surface of a metallic pipe, and an outer skin layer 5 formed on the circumference thereof, a projected bar of the pattern of the diamond lattice shape is swollen out of the surface of the layer 5 by spirally winding a plurality of wires 6 of large diameter between layers, and the diamond is of the size of a part to which a human fingertip is placed. Thus, even when the fingertip is placed on the circumferential surface of the bar 2 in any direction, the fingertip can be hooked to the projected bar, or the fingertip can be firmly pushed in the diamond part.  The grip bar can surely be held without generating any slip both in the circumferential direction and in the axial direction, and the handrail can be fixed to the wall in the desired attitude.

Title: Lubricating oil feeder for rotary piston engine
Inventor: KODAMA HIROSHI
IPC: F02B75/02
Filed: 1979-08-27
Abstract: PURPOSE: To improve lubrication performance and reduce the consumption of lubricating oil, by providing a lubricating oil feed passage, which communicates with an air feed passage, so that the lubricating oil feed passage is opened in the internal trochoidal surface of a rotor housing.  
     CONSTITUTION: A lubricating oil feed passage 15 is inserted into a rotor housing 2 and secured. At an opening 15a, lubricating oil is mixed with air introduced through an air feed passage 20. The lubricating oil is blown from a lubricating oil feed port 13 toward the internal surface 12a of a lubricating oil reservoir 12 so that the oil collides against the internal surface 12a. The inertial force of the lubricating oil is reduced by the collision so that the oil flows out on an inside trochoidal surface 2a. As a result, an oil film is made on the entire inside trochoidal surface to improve lubrication performance.

Title: Automatic gain control device in ultrasonic pulse transmission
Inventor: KURIMURA SHIZUO
IPC: H03G3/20
Filed: 1980-08-11
Abstract: PURPOSE:To avoid the effect of noises and the like inputted into a transmitting path by forming an AGC voltage from only the signal which is sent at every period and has a specified pulse width, a pulse interval, and a transmitting strength. CONSTITUTION:A clock (a) including a sampling signal which is synchronized with an incoming ultrasonic signal is formed by a clock generating circuit 6. The clock (a) is a clock signal for a shift register 9. A switching wave is formed by the clock generating circuit 6, and applied to a switching circuit 8. The input data to the shift register 9 is switched to the output signal of a comparator 5 from the output of the shift register 9. Therefore the content of the shift register 9 becomes a ''1'' level when the amplitude of the received signal is larger than the scheduled value under the state the transmission and reception are synchronized. The output of the shift register 9 is smoothed by an integrating circuit 10 to obtain the AGC voltage (e) and a receiving amplifier 2 is controlled by said AGC voltage (e).

Title: Moving method for optical pickup of optical information recording and reproducing device
Inventor: SHIKICHI SATOSHI
IPC: G11B7/085
Filed: 1985-05-24
Abstract: PURPOSE:To execute the access of information at high speed by setting the one intermittent moving distance of an optical pickup so as to be smaller than the pitch of an information band. CONSTITUTION:DELTAT, DELTAP, and DELTAP''' denote the moving distance of the time when an objective lens 7 moves from on some information band onto an adjacent information band (for instance, 2k+1 from 2k), a distance by which an optical pickup 3 moves by one intermittent movement, and a secondary vibration amplitude generated when the optical pickup 3 is moved by DELTAP in the direction Y, respectively. In case of DELTAP<DELTAT, when DELTAP is set so as to become N.DELTAP>=DELTAT, the secondary vibration amplitude DELTAP''' of the direction Y of the optical pickup 3 also becomes much smaller than DELTAT. Accordingly, the recording or reproducing operation of information of the information band by the objective lens 7 is not influenced by the secondary vibration amplitude DELTAP''' of the optical pickup 3. In this way, the optical pickup 3 can be moved at the high speed.

Filed: 1980-08-13
Abstract: PURPOSE:To realize the same gamma characteristic independently of the change in luminous intensity, by moving the set point level of the approximate gamma characteristic corresponding to the change in the gain of an AGC amplifier circuit at the change in the luminous intensity. CONSTITUTION:When an output signal of an AGC detection circuit 62 is decreased through the decrease in the luminous intensity, a transistor TR702 starts conduction, TRs 703-707 start operation and a current corresponding to the collector current of a TR702 flows to the TRs 705-707. In this case, the base voltage of TRs 103, 104 is decreased by the voltage drop of resistors 717, 718 through a current flowing to the collector of the TRs 706, 707. That is, the level of the gamma set voltage can be lowered equivalently and the control of the gamma set level corresponding to the gain change of an AGC amplifier circuit 61 is made.
