Title: Endoscope
Inventor: AIDA KAZUHIKO
IPC: A61B1/00
Filed: 1989-10-09
Abstract: PURPOSE:To enable prevention of a drop in suction force during suction with a higher sanitary and safe property by providing a forceps plug in which a plurality of sealed films are arranged in a multi-layer structure to improve a higher sealing performance of an instrument inserting section. CONSTITUTION:An instrument inserting section is provided with a forceps opening 10 and a forceps plug 11 mounted thereon. The forceps plug comprises an elastic body and a plurality of sealed films 11b provided with an insertion hole 11d at the center thereof for insertion of an instrument are arranged on the inner circumferential side of a cylindrical plug body 11a in a multi-layer way in a direction vertical to the surface of the sealed film. The outer circumference of each sealed film is fixed on the inner circumference of the plug body 11a. With such an arrangement, even if a pressing force is applied to an insertion hole periphery part of the sealed film when an instrument is inserted and it is operated, the forceps plug is deformed as a whole and the insertion hole of the sealed film moves according to the movement of the instrument 12 to make it hard to generate a clearance between the instrument and the sealed film. Moreover, the sealed film outside a body absorbs most of a pressing force of the instrument to minimize a deformation of the sealed film inside the body. Thus, there is little clearance between the instrument and the sealed film inside the body.

Title: Inspection of optical disk
Inventor: TSURU TETSUO
IPC: G11B7/26
Filed: 1986-11-05
Abstract: PURPOSE:To achieve a higher inspection efficiency visually spotting the position of a defect on an optical disk with ease, by recording a pattern at a point near the position of the defect after the detection of a defect to find the position of the defect with the point recorded as mark. CONSTITUTION:When a defect is detected at a position X in a certain sector on an optical disk 1, a distance Pa on the circumference to the defect position X is determined with the position of recording a synchronous signal in the sector as reference A. Then, a desired light data pattern is recorded at points located at distances P1 and P2 respectively from the reference position A near the defect position X over a range of specified number of bytes and covering specified several tracks. This facilitates visual checking of the location of the pattern when the optical disk is observed. Then, two locations, at which the light data pattern on the optical disk are recorded, are spotted visually under a microscope thereby enabling the finding of the position X of a defect existing between the two locations.

Title: Hydraulic shock absorber
Inventor: SEKINE CHIKAYA
IPC: F16F9/50
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To decrease the hammering noise produced upon opening and closing of a check valve that composes pump means in a self pumping type hydraulic shock absorber. SOLUTION: A valve body 44 having a hydraulic passage 48 is engaged at the top end of a pump rod 32 fixed on the piston rod side. A disc valve 45, which is provided on a valve seat 49 of a valve body 44, a clamp portion 50, and a support convex portion 51, is clamped by a convex portion 52 of a retainer 46 that is externally engaged at the top end of the pump rod 32. The pump rod fixed on the cylinder side is slidably inserted within the pump rod 32, forming a pump chamber 37. The hydraulic pressure from the pump chamber 37 causes a disc valve 46 to deflect and to open, allowing the communication therethrough. Since the disc valve 46 does not bring into contact with any portion at the opening, no hammering noise is produced. Moreover, the disc valve 46 is made of thin and light plate so that only a small hammering noise is produced when it seats on the valve seat 49 at the closing.  Therefore, the operating noise of the hydraulic shock absorber can be decreased.

Title: Hot and cold water mixing valve device
Inventor: TSUTSUI OSAMU
IPC: G05D23/00
Filed: 1985-11-22
Abstract: PURPOSE:To minimize both the overshoot and undershoot and to prevent previously the hunting phenomenon by setting plural switching temperature levels for change to a high speed from a low speed and changing these temperature changes every time the temperature exceeds the reference levels at the positive and negative sides. CONSTITUTION:The switching temperature setting value (a) between the low and high speeds is set by a switching temperature setting/changing means 25 and the value satisfying a1<a2<a3 among these three switching temperature values is set at the positive and negative sides respectively. Then the value (a) is changed as a1 a2 a3 at the positive side and -a1 -a2 -a3 at the negative side respectively every time the switch signal Sw is transmitted from a switching command means 24. A memory control means 27 usually performs the control so that a low-speed characteristic curve is read out of a ROM 28. However the means 27 changes the address so that the low-speed characteristic curve is changed to a high-speed characteristic curve when the temperature difference T between the real temperature TA and the set temperature TO exceeds the 1st switching temperature level a1. Then the switching temperature (a) is changed to the 2nd set value a2. Thus the means 27 can produce a prescribed address by using the value a2 as the data.
