Inventor: YAMAMOTO TOSHIO
IPC: C08G63/00
Filed: 1993-08-18
Abstract: PURPOSE:To efficiently obtain the subject polymer having narrow molecular distribution using a readily available catalyst by subjecting a hydroxy group- containing compound, an epoxide and a cyclic acid anhydride to ring-opening copolymerization, using a specific compound as a catalyst. CONSTITUTION:This polymer is obtained by subjecting a hydroxy group-containing compound (e.g. pentaerythritol), an epoxide (e.g. versatic acid glycidylester) and a cyclic acid anhydride (e.g. phthalic anhydride) to ring-opening copolymerization reaction. Furthermore, as the polymer, e.g. a compound of the formula [A is H or a residue of a hydroxy group- containing compound; Y is a residue of a cyclic acid anhydride; X is H, a halogen, etc.; (n) is 1-10; (m) is 1-100] is exemplified. The ring-opening copolymerization reaction is preferably carried out under nitrogen gas atmosphere at atmospheric pressure and 100-120 deg.C for 5-6hr.

IPC: B22C9/02
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To efficiently remove impurity by directly communicating a sprue and a riser and arranging gates to a prescribed positions on a runner. SOLUTION: In a casting device 2, the sprue 4 for pouring molten metal M and the riser 6 for removing gas, etc., in the molten metal M are arranged. The sprue 4 and the riser 6 are arranged in almost V-shape so as to communicate in the lower parts. The molten metal M is introduced to the runner 10 from the sprue 4 and the molten metal M in the runner 10 is introduced into a cavity in a mold from the gate 14. The runner 10 is introduced out almost horizontally from the communicating part 8 between the sprue 4 and the riser 6. Then, the gates 14 are arranged to the prescribed position on the runner 10. Further, the molten metal M poured from the sprue 4 is decelerated at a choke part 36 to flow into the runner 10 through the communicating part 8. In this case, the impurity G is floated up to the riser 6 due to a difference in sp. grs. and the molten metal M is cleaned.  By this method, shrinkage hole and blow hole, etc., caused by gas are collected into the riser and a product can be made into a sound structure.

Title: Heat exchanger for freezing machine
Inventor: YAMAGISHI KATSUAKI
IPC: F28F1/16
Filed: 1984-09-29
Abstract: PURPOSE:To achieve high efficiency and the reduction in occupying space as well as defrosting energy by making the width of a refrigerating pipe and heater pipe fins wider in the axial direction of the pipes increasingly as they are situated closer to the upstream side relative to the flow of the heat exchanging fluid, and by bending or twisting the fin strips at their root parallelly with the flow of fluid. CONSTITUTION:Since the direction of protrusion of refrigerating pipe fins 15 and heater pipe fins 16 protruding from the surface of a refrigerating pipe 12 and a heater pipe 14 are different from the winding direction of a heat exchanging pipe 11, there is no restraint to the fins due to the winding, and as a result, the surface area can freely be set and a narrower pitch can be selected. Therefore, the occupying space can be reduced, and because the heat exchanging pipe is employed, a high heat exchanging efficiency can be obtained. Since the fin strips 17, 18 are made increasingly wider as they are situated closer to the upstream side relative to the flow of heat exchanging fluid, the cooling effect to the upstream side fin strips which are prone to be frosted is lower than the downstream side, and so, the frosting in the uniform thickness will result. Further, as the heater pipe is contacting the refrigerant pipe to quickly conduct the heat from heater to the refrigerant pipe, the defrosting energy can be reduced.

Abstract: PURPOSE:To provide complete seal, by a method wherein a groove line, filled with a sealer, is formed in the joint of the one panel, a projection line, engaged with the groove line, is formed on the joint of the other panel, and this causes integral continuity of the sealer. CONSTITUTION:A groove line 23 in a panel 3 is filled with a sealer 60 in a manner that the groove line is heaped up with the sealer, and a projection line 36 is engaged with the groove line 23.

The sealer 60 flows over the groove line 23 resulting from engagement of the projection strips 36 with the groove line 23, and a gap at the joint is entirely sealed with the overflowing sealer 60. This enables reliable and entire sealing of the joint, facilitates setting of the panel, and ensures precise positioning of the panel, resulting in the possibility to improve the efficiency of a joining work.

Abstract: PROBLEM TO BE SOLVED: To manufacture in light weight by using wooden material for a main body without using an iron-core choke coil for a stabilizer. SOLUTION: Two chandelier bulbs 2, a capacitor 10, and a switch 9 for changing over two contacts are used in the stabilizer of this fluorescent lamp appliance. The capacitor 10 is connected to one bulb 2 in parallel and the switch 9 for changing over two contacts is connected as seen in a circuit diagram.

Filed: 1991-08-15
Abstract: PURPOSE: To stabilize the quality and to control the consumption of toner by judging actual image forming grain density based on a regulated image forming grain density and adjusting a supplying speed. CONSTITUTION: After measuring a current necessitated for the developing of a standard image, a microcontroller 116 respectively compares a calibration developing current (FDEV) with the threshold value FT of the number of feedbacks to judge whether FDEV is larger or smaller than the threshold value. The threshold value (FT) of feedback is a value taken out from a memory 118 and fixes previously and is the function of desired standard toner density and charging potential given to the standard image. Then when FDEV is larger than a threshold value current (FT) in the case of toner density, a toner repleshing speed is decelerated and when it is smaller, the toner replenishing speed is accelerated to control its average density.

Title: Roller bearing
Inventor: KIYO MANRIYOU
IPC: F16C33/48
Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To arrange a large number of rollers, to endure high load capacity, and to prevent deformation and damage of pins caused by a direct load to the pins. SOLUTION: Rollers 40 rotatably supported by pins 33 of a holder are arranged in large numbers in an annular shape in a bearing space S between an inner ring 10 and an outer ring 20. When clearance between the pin 33 and a pin hole 41 is denoted by (a) and a distance between two rollers 40, 40 is denoted by (b), these values are set so as to satisfy b<2a. Thus, for example, when a load in the direction for approaching both is generated since a speed difference is made between the two rollers 40, 40, both can be brought into contact with each other since the distance (b) between both is set smaller than a both movable distance 2a (b<2a). Thus, a pair of a load applied to one roller 40 is supported by the other roller 40, so that a load directly applied to the pins 33 is reduced by that extent.
