Patent JP-S59221564-A (JP)
Title: Solar heat collector
Inventor: MIYANARI MASAHARU
IPC: F24S90/00
Filed: 1983-05-31
Abstract: PURPOSE:To enable to naturally circulate heat medium without external power by composing a sealed system circuit of a solar heat collector, and a heater added to a hot water storage tank, and sealing heat medium absorbed at a low temperature to a solid absorber and separated at a high temperature in the circuit, thereby installing the tank at the position lower than the collector. CONSTITUTION:Since an absorber 5 sealed in a flow passage of a solar heat collector 1 has a property for absorbing liquid heat medium, the medium is absorbed when the absorber 5 is not heated by solar heat. As the absorber 5 is gradually heated to a high temperature, the absorbed medium is heated, the medium is eventually evaporated, and separated from the absorber 5, thereby forming a high temperature high pressure atmosphere. The medium naturally circulates reversibly between a heater 12 and a solar heat collector due to the pressure difference produced in the collector 1 and the heater 12, and a hot water storage tank 5 can be installed at the position lower than the collector 1 without power source.

Title: Contact structure of motor
Inventor: TORISAWA AKIRA
IPC: H01R39/00
Filed: 1983-06-02
Abstract: PURPOSE:To prevent the deterioration of a commutator by forming at least one of a plurality of brush pieces which are sequentially contacted with and separated from rotating commutator segments of a material different from that of other brush pieces and preparing so that both brushes are not simultaneously separated from the same commutator. CONSTITUTION:A plurality of brush pieces 42, 43 which are contacted with and separated from a commutator 45 having a plurality of commutator segments 44 which rotates in a clockwise direction are mounted on a brush spring 41. The piece 42 is formed of a silver-palladium alloy, and the piece 43 is formed of a gold material. The pieces 42, 43 are varied in length to provide different deflections. When the commutator 45 rotates, the piece 43 is first switched at the contact, and then the piece 42 is then switched at the contact. Thus, the switching timings of the gold system having stable contacting resistance and the silver-palladium system having slightly unstable contacting resistance but hardly forming silicon oxide are different. In this manner, a commutator mechanism having high reliablity can be formed.

Abstract: PROBLEM TO BE SOLVED: To obtain a toner free from a mark of a peeling claw and having goodanti-offsetting property by providing a specified loss modulus of rigidity measured at a specified temperature, a specified frequency and a specified strain amplitude. SOLUTION: This toner has >=6,000 Pa loss modulus of rigidity (G") measured at 200 deg.C, 100 rad/sec frequency and 1% strain amplitude. In the case of <6,000 Pa, a mark of a peeling claw is left on a formed image. A resin for the toner is not particularly limited but preferably has a polymerization degree of >=500, in particular 550-1,350. In the case of <500, the resin has low viscosity and it is difficult for the resin to provide satisfactory anti-offsetting property. In the case of >1,350, fixability lowers. When the resin is a vinyl copolymer having a polymerization degree of >=500, particularly good anti-offsetting property is provided.

Abstract: PURPOSE:To prevent a toner image from existing by providing an irregular reflecting face, which irregularly reflects the light from a light source, on the upper face of an original platen reference part. CONSTITUTION:When an original 4 to be copied is put on an original platen 10 on a transparent substrate and a device is operated, the light from a light source 30 is projected to the surface of the original 4 through the platen 10 and an air layer. Through the gap between a front end part 40 of the original 4 and the reference part of the platen 10 is not covered with the original 4 in this case, the light from the light source 30 is irreqularly reflected on an irregular reflecting face 50 and is transmitted to an optical mechanism 3 and is sufficiently projected onto a photosensitive drum 20 because the irregular reflecting face 50 which irregularly reflects the light from the light source is provided near the reference part. Thus, a toner powder is not stuck to the part of the drum corresponding to the original platen reference part 110. consequently, the light irregularly reflected on the irregular reflecting face 50 is projected to the drum 20, and the front end of a copy paper passes the part where the toner is not stuck, and the toner is not transferred to this front end part from the drum 20.

Title: Refinig method of copper alloy
Inventor: MACHITORI HARUKA
IPC: H01B1/02
Filed: 1979-08-07
Abstract: PURPOSE: To make possible the manufacture of pure copper alloy with low degree of oxidation without using melting under vacuum and ingot casting of copper alloy, by melting the alloy in the air using a carbon crucible, and by using a portion of copper as a cooling material.  
     CONSTITUTION: In melt and ingot casting of Cu-Cr or Cu-Zr alloy, a carbon crucible is used for melting. Electrolytic copper 10% less than necessary amount of Cu is melted in the carbon crucible. Dissolved oxygen contained in the Cu is removed with C of the crucible as CO 2 , so that the electrolytic copper may be melted in the air. When the electrolytic copper is melted in the crucible, Cu-Cr mother alloy is added to the electrolytic copper in order to melt it thereby forming alloy. Then the residual 10% electrolytic copper is added and melted to produce molten metal of Cu-Cr, which is quenched and cast in order to reduce the time for absorbing oxygen from the air. In the case of Cu-Zr alloy, Zr is added in two steps, i.e., it is first added in the form of Cu-Zr mother alloy for the purpose of deoxidation, then in the form of Cu-Zr mother alloy as alloying material thereby preventing the decrease in the yield of addition.

Title: Forming method for semiconductor quantum box
Inventor: KITAMURA MITSUHIRO
IPC: H01L29/06
Filed: 1988-04-21
Abstract: PURPOSE:To improve uniformity of the size of a quantum box by mixing crystals of a quantum well structure in a spot state, and forming the box in which mixed crystal is not formed in its gap. CONSTITUTION:Many mixed crystal regions are generated in a spotlike region 5, and a quantum box is formed in its gap part 6. In order to form the mixed crystal region, an impurity ion implanting method, a laser beam radiating method, etc., can be employed. Accordingly, since the box is formed in the gap of FIB spots having relatively uniform size, even if the spots having, for example, approx. 1000Angstrom  of diameter are slightly irregular in size, the irregularity of the sizes can be cancelled in the gap part. Thus, the box having uniform size of approx. 200Angstrom  of one piece can be formed.
