Title: Stylus tip protection device for record player
Inventor: YAMAGUCHI HARUNOBU
IPC: G11B19/14
Filed: 1986-04-30
Abstract: PURPOSE:To prevent damage of the stylus tip mounted to a tone arm even with mis-operation with simple structure by returning the tone arm to the playing stop position when the pitch of a groove of a plate member is a prescribed value or over while the stylus is moved in the direction of the plate member of the tone arm due to mis-operation. CONSTITUTION:If the playing state is attained through mis-operation without any record disk, the stylus 6 drops on a position Y or Z. In case of the position Y, when the size of the turntable 3 is selected smaller than the position Y, the stylus tip is not damaged. If the stylus 6 drops onto a position Z, the stylus 6 drops onto the plate member 8. When the pitch of a spiral 7 is a prescribed value or over, an arm fixing lever 24 is driven quickly and then a cut lever 13 is driven quickly, then a claw 40 of a small gear 16 and the end of the 2nd clutch plate 15 mesh with each other, an arm elevating/descending drive mechanism 10 is operated before the stylus 6 is proceeded to the automatic return position 35R to attain the automatic return and the tone arm 2 is restored to a rest base 63.

Title: Production of glass
Inventor: KURODA HIROSHI
IPC: C03B19/12
Filed: 1987-04-24
Abstract: PURPOSE:To improve the yield of products and to reduce the producing time by placing a wet gel obtained from a metal alkoxide as the essential raw material in an air-permeable vessel, and then depressurizing the vessel. CONSTITUTION:An aq. soln. contg. a metal alkoxide as the essential component is heated, agitated, and mixed to form a mixed sol, which is transferred into an air-permeable vessel 2 made of a porous polymer, etc. The vessel 2 is then put in a reduced-pressure repository 3, the surroundings of the vessel are depressurized, and the raw sol is gelled and dried at appropriate temp. and humidity. The dry gel 4 is finally sintered at about 1,000-1,200 deg.C to obtain a product. Since the wet gel is dried by using the air-permeable vessel 2, the whole surface of the gel is uniformly dried. Moreover, since the surroundings of the vessel 2 are depressurized, the drying time is drastically reduced. As a result, the yield of products is improved, and the producing time is reduced as a whole.

Title: Platen driving device
Inventor: ADACHI TETSUYA
IPC: B41J11/00
Filed: 1990-04-17
Abstract: PURPOSE:To make a pin mesh with a guide slot by providing a Geneva stop wherein a driving gear is equipped with a notch corresponding to a rotational path of a driven gear as a means for transferring a torque of a motor to a platen. CONSTITUTION:A motor 4 rotates and a circular arc of a driving gear 7 contacts with a fin 8a, so that positions of the driving gear 7 and a driven gear 8 are corrected to positions where a pin 7b meshes with a guide slot 8b. The pin 7b of the driving gear 7 meshes with the guide slot 8b of the driven gear 8, the driven gear 8 begins to rotate so as to drive a platen 2. The driven gear 8 further rotates and stops when the mesh of the pin 7b with the guide slot 8b is completed. A position of the platen 2 at this time is kept by a mesh of a ratchet gear 10 with an arm 11. At this time, an optical sensor 13 outputs a detecting signal so that the motor 4 is stopped. Since the positions of the driving gear 7 and the driven gear 8 are corrected to the positions where the pin 7b meshes with the guide slot 8b, the driving gear 7 and the driving gear 8 can well mesh with each other even if the positional relation between the meshing position of the ratchet mechanism and the pin 7b and the guide slot 8b is not good.

IPC: B01J27/00
Filed: 1987-04-24
Abstract: PURPOSE:To obtain the titled compound useful as a raw material for chemicals, in high selectivity and yield at a low cost, by contacting naphthalene with CO, O and a carboxylic acid in the presence of a palladium-based catalyst and 1,10-phenanthroline. CONSTITUTION:Naphthoic acid can be produced by contacting naphthalene with CO and O and/or carboxylic acid (e.g. acetic acid, preferably glacial acetic acid) in the presence of a palladium-based catalyst (e.g. palladium acetate, palladium chloride, etc.) and 1,10-phenanthroline. It is preferable to use sufficiently purified naphthalene in the reaction to prevent the side reactions. The amount of the palladium-based catalyst is usually 0.001-50mol, especially preferably 0.002-30mol per 1mol of naphthalene. The process improves the selectivity of beta-naphthoic acid useful as a raw material for polyester, etc., and increases the overall yield of naphthoic acids.

Title: Compression dehydrater for garbage
Inventor: SANO MASAKAZU
IPC: E03C1/266
Filed: 1988-04-25
Abstract: PURPOSE:To prevent counterflow of waste water through a drainage hose, in a compression dehydrater where the pressure in a decompression chamber is reduced to lift a pressure receiving board so as to move a piston upward thus compression dehydrating garbage, by performing open/close control of a drainage solenoid valve based on the piston of the pressure receiving board. CONSTITUTION:A drainage solenoid valve 28 is closed while an exhaust solenoid valve 21 is opened to drive a vacuum unit 22 so as to depressurize a decompression chamber 18. Consequently, a decompression board 17 lifts to cause lifting of a piston 24 thus compression dehydrating garbage between the piston 24 and a cover body 11. Upon finish of compression/dehydration for a predetermined time, the vacuum unit 22 is stopped and the exhaust solenoid valve 21 is opened to lead air into the decompression chamber 18 so as to lower the decompression board 17. When the decompression board 17 lowers sufficiently to cause function of a position sensor 32, the drainage solenoid valve 28 is opened to discharge stored water through a hose 29. By such arrangement, counterflow of waste water through the drainage hose can be prevented.
