Inventor: HAYAMI HIROSHI
IPC: C08J9/06
Filed: 1987-08-08
Abstract: PURPOSE:To provide the title blowing agent which can form fine closed cells in a polyolefin resin and can easily control the diameter of a cell, by causing an inorganic powder to adsorb a substance which can be gasified at a temperature >= the softening point of the polyolefin resin. CONSTITUTION:An inorganic powder is caused to adsorb a substance which can be gasified at a temperature >= the softening temperature of the polyolefin resin to be expansion-molded (e.g., n-tetradecane or n-decanol) to constitute a blowing agent for expansion molding of polyolefin resin. As said inorganic powder, a zeolite powder is suitable, and when the diameter of a cell is to be adjusted to 100mu or smaller, it can be performed by using a zeolite powder of a median particle diameter of 0.1-1mu. The zeolite powder after adsorption of an adsorbate can be easily mixed with a polyolefin resin in good dispersibility by means of, the example, roll mixing, and therefore it does not undergo fracture during mixing.

IPC: G11B21/20
Filed: 1985-09-09
Abstract: PURPOSE:To prevent the degradation in head touch to make stable recording and reproducing possible by providing a means with which the second carriage is brought into contact. CONSTITUTION:An elastic body 11 is compressed and inserted between an upper carriage 4 and a spring holder 12, and the upper carriage 4 is brought into close contact with a face 7a on a plane through a suspension 6 by the repulsion for the purpose of supporting pivotally the upper carriage 4 on a lower carriage 7. Since the state where the upper carriage 4 is brought into close contact with the lower carriage 7 through the suspension 6 is stabilized and the suspension is not deformed to an approximately arcuate shape, the positional deviation in the diametral direction of an upper head from the recording and reproducing position on a disc 2 and the resonance of the upper carriage 4 are prevented. Since the upper head 3 is brought into close contact with a lower head through the disc stably, the degradation of contacting, where even several microns gap cannot be permitted, between recording and reproducing required parts of the lower head 8 and the upper head 3 and the disc is prevented.

IPC: H01L23/28
Filed: 1988-08-10
Abstract: PURPOSE:To prevent a semiconductor element from cracking and wiring from being damaged by forming a cavity in a region opposite to the element surface of the semiconductor element in resin to seal the semiconductor element. CONSTITUTION:A semiconductor element 1 is mounted on the element mounting part 2a of a lead frame 2 and the electrode pad and the inner leads 2b of the lead frame 2 are connected to each other with metallic fine lines 3. The semiconductor element 1, the inner leads 2b, and the metallic fine wires 3 are sealed by molding with resin 4 to make a package and outer leads 2c are protruded on the side faces of the resin 4.

IPC: H04L1/00
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To fetch parallel data with inter-data skew automatically adjusted by providing a parity check circuit and an output circuit, etc., that makes the outputs of 3rd and 4th flip-flops which are decided as no parity error by the circuit a receiving output. SOLUTION: 3rd and 4th flip-flops 13 and 14 make the outputs (1) and (2) of 1st and 2nd flip-flops 11 and 12 coincide with the phase of a clock CLK, and their outputs (3) and (4) are inputted to a selector 16. A parity check circuit 15 performs parity check about the output (3) of (n+1)-bit including a vertical parity bit of the flip-flop 13. When the circuit 15 does not detect a parity error, that is, when the flip-flop 11 normally fetches parallel data, the selector 16 selects and outputs the output (3) of the flip-flop 3 by a check output signal that does not have an error and makes it a receiving output (7).

Title: Degaussing circuit
Inventor: IKEDA YUTAKA
IPC: H04N9/29
Filed: 1994-08-24
Abstract: PURPOSE: To eliminate the adverse influence of a residual current by connecting a second positive characteristic thermistor between the gate electrode of a TRIAC and the AC power source side of a degaussing coil. CONSTITUTION: Main electrodes 15a and 15b of a TRIAC 15, first positive characteristic thermistor 12 and degaussing coil 13 are serially connected at both the terminals of an AC power source 11 and a second positive characteristic thermistor 22 is connected between a gate electrode 15c of the TRIAC 15 and one terminal on the AC power source 11 side of the degaussing coil 13. After the TRIAC 15 is turned off and a color television receiver is completely degaussed, the current to flow to the degaussing coil 13 is cut off. Thus, the oscillation of a picture can be prevented from being generated by the residual current to flow to the degaussing coil 13.  Besides, since power to be supplied to the first positive characteristic thermistor 12 is decreased by cutting off the residual current, the load to be applied to the first positive characteristic thermistor 12 is reduced and the service life of the first positive characteristic thermistor 12 can be prolonged.

Abstract: PURPOSE:To attain the light weight without losing the strength, rigidity and face accuracy by forming plural recesses made by notching the rear side to the rear face of a sandwich structure in an antenna system where the reflection mirror is made of the sandwich structure adhering a skin member to both sides of a core member. CONSTITUTION:Many of recesses 14 formed at the rear face by eliminating partially a back skin b2, a core (a) and an adhesive (c) of the reflection mirror 11, the pattern can be circular or square. Skins b1, b2 are made of a material such as CFRP and formed by an autoclave. In emphasizing especially the face accuracy, the core (a) whose height is lowered is left. When it is required to take the improvement of the rigidity into account in addition to the face accuracy, the core (a) whose height is lowered is left and a back skin b2' thinner than the normal back skin b2 is adhered to the part thereby improving the rigidity and face accuracy. Thus, the weight of the reflection mirror 11 is lightened.
