Title: Refractory structure of molten metal-holding container and breaking-up method for lining using the structure
IPC: F27D1/00
Filed: 1992-03-14
Abstract: PURPOSE:To alleviate burden on to workers and to improve working environments, by a method wherein refractory linings for a molten metal container such as an induction furnace are easily broken up. CONSTITUTION:In a molten metal container 16 such as a melting furnace or a ladle wherein a molten metal is held, which consists of an outer shell 18 and refractory linings 22 wherewith the inner walls and bottoms thereof are lined, a calciums carbonate-made intermediate layer 24 is placed between the outer shell 18 and the linings 22. High temperature of the molten metal held in the container turns calciums carbonate into calcium oxide, using such refractory structure. When these linings are broken up, the intermediate layer is moisturized and the calcium oxide is turned into calcium hydroxide, and thus these linings can be easily broken up.

Title: Brake oil pressure control valve for vehicle
Inventor: MIZUSAWA MITSUTOYO
IPC: B60T8/1766
Filed: 1982-05-26
Abstract: PURPOSE:To permit proportional control and antilock control without generating kickback to a master cylinder by installing a piston for releasing the power of the set spring of a hydraulic control valve by means of a control pressure and allowing said piston to operate when wheels are locked. CONSTITUTION:The hydraulic pressure to a rear wheel brake Br is controlled by a proportional reducing valve constituted of a decompression piston 21 and a set spring 23, and decreased in comparison with a front wheel brake Bf. A control circuit 29 switches a solenoid valve 24 on the basis of a signal from a wheel sensor 30 and introduces the oil pressure from a pump 28 into a controlled oil- pressure chamber 36. Therefore, a control piston 35 allows the decompression piston 21 to retreat against the power of the set spring 23. Then, a valve 15 is closed, and an output hydraulic pressure chamber 11 is spread to weaken the rear-wheel brake power. Since a pressure receiving piston 6 is not applied with the power of the control piston 35, kickback to a master cylinder is not generated.

Title: Focus detector
Inventor: SHINODA MASAHISA
IPC: G11B7/09
Filed: 1984-05-04
Abstract: PURPOSE:To ensure the stable focus detection even when the light crosses a guide groove by defining the photodetecting part of the luminous flux received by a photodetector as a blind sector when a converging lens is set at a focused position to an information carrier. CONSTITUTION:In a focused mode a light spot 13 has the same size as a blind sector 19e of a four-split photodetector 19, and the outputs given from photodetecting surfaces 19a-19d goes to zero. Thus the focus error output obtained through an arithmetic goes to zero. While in an out-of-focus mode the spot 13 becomes oval, and a positive or negative focus error outputs 23 is obtained through arithmetics 20-22. Therefore the ripple produced by the effect of the diffraction caused when a converging spot crosses a guide groove is eliminated at a position near a focused point. This ensures the satisfactory focus detection characteristics with no focus position error.

Abstract: PURPOSE: To produce a cylindrical container at a low cost by turning a cylindrical container after gelation of a resin and by irradiating ultraviolet rays with an unforced air-cooled ultraviolet lamp while spraying water inside the container.  
     CONSTITUTION: Unsaturated polyesters mixed with a polymerizable monomer such as styrene or products obtained by the reaction of a polyepoxide with an unsaturated monobasic acid in the presence of addition catalyst are molded to produce a cylindrical container by leaving aline after gelation. With this cylindrical container 1 placed on a revolver 5 an unforced air-cooled ultraviolet lamp 2 is switched on and at the same time water is sprayed by a water sprayer 4. And the cylindrical container is turned around at the speed of irradiating ultraviolet rays inside the container for 10W60 seconds. After irradiating the entire inside, the ultraviolet lamp and water are cut and the cylindrical container is disconnected to give a finished product. Thus, because unreacted organic compounds in the products can be reduced at a short time, they are suitable for food container use.
