Title: Synthetic resin-formed object
Inventor: SUGA TETSUO
IPC: B29D11/00
Filed: 1989-11-17
Abstract: PURPOSE:To reduce the change of the angle near a corner by a method in which in the formed object wherein two crossing planes made of synthetic resin are used as optical reflecting surfaces, the reinforcing walls connecting the corner at which said two planes mutually cross to the part between each edge of both ends of mirror surfaces, are constituted, while the through hole which opens at the reflection side of the corner and does not connect each edge is provided. CONSTITUTION:In a synthetic resin-formed object 1, flat plates 2 and 3 mutually cross, and their inside opposite surfaces are mirror surfaces 4, 5. Said surfaces mutually cross perpendicularly at its corner, and edge parts 7-10 are provided at both ends except the effective range of each mirror surface 4, 5. Triangular reinforcing walls 11, 12 are provided to the half way position of each edge part 7-10 with the apex of the corner 6. Releases 13, 14 are provided in the space formed by each edge 7-10 provided with no reinforcing walls 11, 12. By above construction, the deforming force of warping in the inside and outside directions generated at the side 4a, 5a of the corner of the mirror surfaces is cut and the deforming force may be concentrated at the sides 4b, 5b of an opening, thereby minimizing the value of deformed angle at the corner 6. Further, the heat to be radiated from the releases 13, 14 to the mold is increased, and the warpage value of the mirror surfaces 4, 5 is minimized.

Title: Ball for ball game with chain net on spherical surface thereof
Inventor: TAIKO JUN
IPC: A63B37/00
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To minimize error caused by making a ball bouncing off hands along with a comfortable touching requiring no glove by arranging a chain net on the spherical surface of a soft ball to make it easily fit on palms of hands when caught with bear hands even allowing fingers to be easily hitched on a mesh or the like even when caught about the fingers. SOLUTION: A chain net 1 is provided on the spherical surface of a soft ball. Chains are connected by a triangular ring at a tie part 2 of meshes to form a chain net 1 as illustrated covering the spherical surface. A foaming fluffy base body of the ball is made of a material with limited repulsiveness only to maintain the shape thereof. The chain is characterized by large flexibility in nature. And there is no bouncing because of the absence of repulsive force. Diversity of impact on palms and touch thereon is obtained by varying the type of metal or the hardness of a resin material or the like. In the structure of the ball fibrous material such as kapok may be used instead of the ball made of the foaming material as base body.

Title: Fifo memory using volatile memory
Inventor: KUBOTA SHINICHI
IPC: G11C7/00
Filed: 1999-10-22
Abstract: PROBLEM TO BE SOLVED: To provide an FIFO memory using a volatile memory whose data transferring performance is improved. SOLUTION: When a refresh time lapse timing signal RFTM is generated, a refresh operation is performed only to a memory cell connected with the line address of an address region interposed between a write address WADR and a read address RADR in which valid data as an FIFO operation are stored among the whole line addresses of a volatile memory 7 in response to a refresh request signal RFRQ. Thus, the number of times of the refresh operation can be suppressed by a refresh controlling means. Therefore, the number of data to be refreshed in the FIFO can be reduced, and the number of times of the generation of the refresh request can be reduced, and a time to be spent on the refresh operation can be reduced, and that spare time can be used for reading access and writing access.

Abstract: PROBLEM TO BE SOLVED: To protect a lower structure and facilitate sticking of the metallization of an upper layer by a method wherein an insulating protective thin film is stuck to a wafer by a plasma reinforced CVD method with N2 as a nitrogen source and without using ammonium salt precursor. SOLUTION: A wafer is transferred onto a preheating sample holder for heating within a range of 250-400 deg.C and the wafer is heated to a sticking temperature (101). Then a plasma treatment process is carried out and the chemical composition of the boundary of the film/substrate is additionally controlled (102). Successively, the sticking of a WF2 /N2 /H2 thin film is carried out in a plasma reinforced chemical vapor deposition reaction chamber (103). After that, while a plasma power is continuously applied, N2 and H2 gas is continuously made to flow to control a surface nitrogen concentration additionally (104). If necessary, the quick heat annealing is carried out to lower resistivity and increase a film density and the performance of the film can be improved.

Title: Electromagnetic proportional pressure control valve
Inventor: OGAMI SHIRO
IPC: F16K11/07
Filed: 1998-10-22
Abstract: PROBLEM TO BE SOLVED: To reliably suppress the surge and hunting generated on the secondary pressure when the feed current to a proportional solenoid is abruptly changed. SOLUTION: A body 4 is provided with an inlet port 1, an outlet port 2 and a drain port 3, and a spool 5 is inserted into a valve hole. A plunger 6 applies thrust to the spool 5 via a proportional solenoid 7. A pressure control pin 11 presses the spool 5 via the pressure of a pressure control chamber 9 communicated with the outlet port 2 against the thrust of the plunger 6. This pressing force (pressure of the pressure control chamber 9) is balanced with the thrust of the plunger 6 by the feed current to the proportional solenoid 7, and the secondary pressure of the outlet port 2 is determined by the feed current to the proportional solenoid 7. An accumulator 12 is connected to the pressure control chamber 9. The fluctuation of the secondary pressure is suppressed by the accumulator 12 via the pressure control chamber 9 even when the feed current is abruptly changed.

Title: Coating device for mold release agent
Inventor: AOKI FUMITAKA
IPC: B05C1/02
Filed: 1986-12-19
Abstract: PURPOSE:To supply a sufficient quantity of mold release agent even at the time of continuous copying and to prevent overflow of the release agent even during waiting for copying by making the contacting area of a porous member, which is placed above in the running direction, smaller than that of a porous member placed below. CONSTITUTION:A porous resin member is divided and arranged in plural positions, and the roller contacting area of a member 12a placed above in the roller rotation direction is made smaller, and that of a member 12b placed below is made larger. The release agent is less discharged from the member 12a above having a smaller contacting area, and the discharged release agent is stagnated near the contacting part between the roller and the member 12a above by the capillary phenomenon or the surface tension and does not flow out to the area above the member 12a. The release agent whose quantity is required for continuous copying is discharged from the member 12b below. Though the quantity of the release agent is too large during waiting for copying and the release agent flows along the roller, it is dammed by the member 12a above and is stagnated.
