Patent JP-H0292607-A (JP)
Title: Injection molding
Inventor: NISHIZAWA KIYOSHI
IPC: B29C45/26
Filed: 1988-09-30
Abstract: PURPOSE:To leave no weld at the thin wall portion of a plastic molded item and make the external appearance favorable by a method wherein the thin wall portion of a cavity is opened at the filling of resin so as to make that portion nearly equal in thickness to the thick wall portion and, after that, the cavity is closed until the thin wall portion of the plastic molded item returns to its regulated position. CONSTITUTION:When molten resin is fed in a mold by abutting a nozzle 13 against a nozzle stiffening plate 1a, the molten resin is fed through a sprue 15 part into a cavity. Since pressure oil is fed to the pipe line 5a of a body 5 at this time, a piston 6 is moved rightwards by means of oil pressure sealed by seals 9 so as to move a compression pin 7 also rightwards, resulting in producing no thin wall portion in the cavity, by which a plastic molded item 14 is molded, and uniformly filling molten resin therein. Following thin, when pressured oil is fed to the pipe line 5b of the body 5, the compression pin 7 is moved leftwards so as to compress the molten resin in order to regulate the inner diameters of a thin wall portion 14a and of a thick wall portion 14b. Thus, neither weld nor scorch develops at the thin wall portion of the plastic molded item, resulting in allowing to obtain a molded item excellent in external appearance.

IPC: G11B20/10
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To mitigate the load of a control microcomputer and to shorten a response processing time at the time of restarting take-in processing of data when processing is restarted and data series stored in a buffer memory are coupled after interruption of take-in processing of data. SOLUTION: When data is taken in a buffer memory 111 from an optical disk signal processing section 109, the data is stored and updated in a buffer circuit 104 for comparing data series as data series for comparing based on a control signal of a data take-in comparing timing control section 113. When processing is restored and data coupling is performed in the buffer memory 111 after interruption of data take-in processing, as a data series comparing section 103 can use data string for comparing stored/updated in the buffer circuit 104 for comparing data series during data take-in processing, it is not required that the control microcomputer 110 sets data of the buffer memory 111 to the buffer circuit 104 for comparing data series conventionally.

Title: Securing device for top plate for under floor type foot warmer wooden frame
Inventor: KANEKO NOBUYOSHI
IPC: F24C15/10
Filed: 1989-09-22
Abstract: PURPOSE:To secure a top plate to an under floor type foot warmer wooden frame in an unmovable state and to facilitate release of the top from a securing state by a method wherein a fixing tool is removably mounted on a support member by means of a fastening screw with a control button, and an actuating rod pulls down an actuating ring suspended from the outer surface of an adsorber. CONSTITUTION:When an under floor type foot warmer wooden frame is not used for an under floor type foot warmer, a leg piece 24 loosely inserted externally of a support member 17 is firmly fastened by means of a fastening screw 25 through rotation of a control button 25A. When, after a fixing tool 20 is firmly mounted to the support member, the upper surface of the foot warmer wooden frame is covered with a top plate B, the top plate is supported by resilient members 3A, and the under surface of the top plate is adsorbed by means of adsorbers 21 of the respective fixing tools and the top plate is secured in an unmovable state. By rotating the control button in the reverse direction to the above, a clearance is produced between the fastening leg and the unfastened support member. Thereby, by inclining the fixing tool toward the corner side of a frame body 1, an actuating ring 27 is pulled down by an actuating rod 26 and therefore, a part of the adsorber 21 adsorbed to the under surface of the top plate is separated away from the top plate and air flows in the adsorber. Thus, the fixing tool can be easily removed from the support member, and the top plate can be released from a fixing state.

Title: Oil-free scroll type fluid machinery
Inventor: UENISHI MAKOTO
IPC: F01C17/06
Filed: 1984-11-22
Abstract: PURPOSE:To remove a slidable part by supporting the thrust load by a pin crank equipped with thrust bearings having a radial bearing which are arranged between the back surface of the edge plate of a turning scroll and a casing and keeping the gap between the both scroll edge plates constant, in the turning scroll. CONSTITUTION:When operation is started, a turning scroll 106 supports the thrust load by with collar having thrust bearings 110 having a radial bearing which are arranged at several positions between the back surface of the edge plate 106a and a casing 102. Therefore, turning movement is performed, keeping a certain gap (c) between the edge plate 106a and the undersurface of a fixed scroll 101. Therefore, the inside of the casing 102 is formed into the vacuum range equal to a suction chamber 101a. Since, in this case, bearings 103, 107, and 110 are sealed by the grease having a low vapor pressure, outside leakage is prevented, and the communication of the above-described vacuum range to the atmospheric-pressure side through a shaft part is cut-off by the bearing apparatus 111. With such constitution, the slidable part between the both scrolls can be removed, and the sealing performance can be improved markedly.

Filed: 1991-09-26
Abstract: PURPOSE:To furthermore improve the quantity of reproduced sound by connecting a trap circuit having trap frequency levels equal to respective center frequency levels of an FM main sound signal and an FM sub-sound signal to a communication line for a low band conversion carrier chrominance signal. CONSTITUTION:In a color video signal recording circuit for mixing an FM brightness signal, a low band conversion carrier chrominance signal and FM main and sub sound signals, supplying the mixed signal to a recording means (rotary magnetic head) 13 and recording the mixed signal in a recording medium, the trap circuit 9 having trap frequency levels equal to respective center frequency levels of the FM main and sub sound signals is connected to the low band conversion carrier chrominance signal transmission line.
