Title: Compact disk player
Inventor: ONOZUKA TOMOJI
IPC: G11B27/10
Filed: 1988-10-28
Abstract: PURPOSE:To avoid such a state where the users get easily tired and to set the playing order of music with no manual operation by preparing a random play instruction key, a random number sequence memory part, an arithmetic part, and a playing order register. CONSTITUTION:A random play instruction key 1 instructs the start of an arithmetic operation to an arithmetic part 2 to produce a random number sequence that designates the playing order of music. A memory part 3 consists of a fixed memory and gives the addresses to each random number sequence at and after its head when storing the random number sequences. A playing order register 4 stores the random number sequences which are obtained as the arithmetic results of the part 2. Then the part 2 produces the random number sequences in the number corresponding to the number of music stored in a compact disk. Therefore the playing order of music can be set at random. Thus it is possible to avoid such a state where users get easily tired and to set the music playing order with no manual operation.

Title: Bourdon tube pressure gauge
Inventor: MIYASAKA TERUAKI
IPC: G01L7/04
Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To provide a Bourdon tube pressure gauge which does not cause pressure leakage even when a fastening nut is somewhat relaxed, and excels in a sealing property. SOLUTION: An external thread part 3b is formed in the circumference of the pressure introducing tube part 3 of a Bourdon tube pressure gauge, and a circumferential groove 10 more deeply perforated than the bottom level of the valley of the external thread part in the midway region to separate the external thread part 3b into a tip-side external thread part 3ba and a back-side external thread part 3bb is formed. The pressure introducing tube part 3 has a fastening nut 7 screwed into the back-side external thread part 3bb, O-ring 12 fitted into the tip side of the circumferential groove 10 and a washer 14 floatably fitted into the circuferential groove 10. Since the elastic restoring force of the O-ring 12 always gives the force in the direction of an arrow A from a mounting hole 5 to both of the nut 7 and the pressure introducing tube part 3, a screwing part is hard to relax.  Even when the screwing of the nut 7 and the back-side external thread part 3bb is somewhat relaxed, the force in the direction of an arrow A does not abruptly vanish and therefore the screwing is hard to relax. Even when the screwing is somewhat relaxed, there is hardly possibility of pressure leakage by the O-ring 12 in an opening edge.

Title: Fixed cylinder type radial piston pump
Inventor: KOHARI YUJI
IPC: F04B1/047
Filed: 1988-10-29
Abstract: PURPOSE:To prevent the occurrence of cavitation and to reduce noise and vibration by providing a shielding member where a suction fluid from a suction side port collides in the interior of a piston and boring an orifice passage in the shielding member. CONSTITUTION:A shielding wall 23 is provided in the interior of a piston 11. The partition wall 23 divides a cylinder chamber 13 of the piston 11 into the first cylinder chamber 13a and the second cylinder chamber 13b. Both cylinder chambers 13a, 13b are communicated with each other by an orifice passage 23a. When a fluid which flowed in from a suction side port 14 collides with the inner surface of the shielding wall 23, a fluid is diffused along the shielding wall 23 while the collision energy is converted to pressure energy. Thus the occurrence of cavitation can be prevented to reduce noise and vibration.

Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor sealing material reduced in void formation and excellent in cracking resistance and heat shock resistance in wet soldering by formulating an epoxy resin composition with a mixture of a specified silicone compound with a specified silane compound in a specified mixing ratio. SOLUTION: A composition mainly consisting of an epoxy resin, a hardener and an inorganic filler is formulated with an additive comprising at least one silicone compound represented by formula I or/and at least one silane compound represented by formula II (wherein R<1> and R<2> are each H or a 1-5 C alkyl; R<3> and R<4> are each H; and n is 1-10) in such amounts that the molar ratio of the 1-5 C alkoxyl groups to the hydroxyl groups is 0-3 to obtain an epoxy resin composition. When used to seal semiconductor devices, this composition is reduced in void formation, gold wire flow, etc., and is excellent in cracking resistance in wet soldering in surface mounting.  Even when a biphenyl epoxy resin represented by formula III (wherein R<5> is H or a 1-4 C alkyl; and m is 1 or 2) is used as the epoxy resin, the composition can inhibit void formation and is capable of being highly filled with a filler.

IPC: G06F7/02
Filed: 1988-10-29
Abstract: PURPOSE:To comparatively increase an operation speed and to reduce the number of elements so as to allow the title magnitude comparator to be applied to integration by executing the cascade connection of magnitude deciding parts in accordance with the number of bits of a digital input signal for comparing these magnitude deciding parts to constitute the comparator.

The output control means 30A outputs a decision output from a decision input terminal 3a to a decision output terminal 4a at the time of coincidence of both the input signals A0, B0, and at the time of discrepancy, outputs a compared output from the comparing part 20A as a decision output and the compared output is obtained from the final magnitude deciding part. Consequently, the operation speed is comparatively improved, the number of elements are reduced and the magnitude comparator to be applied to integration is obtained.

Then, the electromagnetic solenoid 15 is operated a plurality of times, after a prescribed time, and the nozzle hole 13A is opened and closed a plurality of times by the needle valve 16. Finally, the needle valve 16 is operated so that the nozzle hole 13A of the nozzle part 13 is opened and the combustion of a combustion part is stopped. Thus, tar adhering to the nozzle hole 13A or the needle valve 16 can be removed so that it is not stayed therein.

Title: Bed device
Inventor: IKEDA MINORU
IPC: A47C19/00
Filed: 1994-10-13
Abstract: PURPOSE: To make a frame recognizable even in a dark place, and dispense with installing labor by bending one end side both corner parts in the lengthwise direction of the frame, and applying fluorescent paint to the corner parts. CONSTITUTION: When the house interior in which a bed device is placed becomes dark, fluorescent paint 7 which absorbed sunlight and light energy of a lamp or the like emits light. Since this fluorescent paint 7 is applied to bending corner parts 4a of a connecting member 4, the light emitting fluorescent paint 7 clearly expresses the corner parts 4a of the bed device in a dark place. Therefore, since its position can be reliably seen, a danger of running against the bed device is eliminated. Since the fluorescent paint 7 is applied to one end side corner parts in the lengthwise direction of the bed device and also to bending places, these can be recognized from any position, and light is emitted more efficiently.  When light emitting capacity of the fluorescent paint 7 is deteriorated, it works well when fluorescent paint 7 is faced, and these can be simply repaired without requiring labor to remove or install a fluorescent material.
