Title: Key sharing system
Inventor: KAWAMURA SHINICHI
IPC: H04L9/08
Filed: 1988-03-10
Abstract: PURPOSE:To economize the title system and to also heighten the reliability of the system by ciphering key sharing information by using each built-in master key and transmitting ciphered sharing information to a receiving side. CONSTITUTION:When a cipher is to be communicated from a code 1 to nodes 2-m by using a common key Kc, an identification number ID1 from an identification number storing circuit 11 and a random number R1 from a random number generating circuit 15 are synthesized at a synthesizing circuit 17 in a key sharing data transmitter 10 of the node 1. Thereafter, the synthesized signal is ciphered at a ciphering circuit 18 by using a master key Km from a master key storing circuit 13, and the ciphered result is further synthesized with identification numbers ID2,..., IDm by a partner identification number synthesizing means 12 and transmitted through communication circuits 30 to respective key sharing data receivers 20 of the respective nodes 2-m. Thus, since the key sharing information is ciphered by using each built-in master key Km and transmitted to the receiving side, the key information cannot be obtained by a third party even when the third party taps the key information.

Title: Optical semiconductor device
Inventor: NIWAYAMA KAZUHIKO
IPC: H01L31/111
Filed: 1984-03-23
Abstract: PURPOSE:To simplify the assembling work and to reduce the irregularity in minimum light trigger power of the titled semiconductor device by a method wherein, in the semiconductor device which performs a diaphragm action on the light made to irradiate on a light-receiving surface, the diameter of light emitting end of the internal light guide is made larger than the diameter of the light-receiving surface. CONSTITUTION:The outlet diameter b1 of an internal light guide 11 is formed larger than the diameter (a) of an element light-receiving surface 5. Among the lights emitted from the light emitting end face of the light guide 11, the light emitted from the part directly above the light receiving surface 5 is made incident on the light receiving surface 5, and it is turned to the light which is effective to a trigger. On the other part, the light is made to irradiate on the outside part of the light receiving surface and it gives no effect on the trigger. Accordingly, if the distance (d) is 0<d<(b1-a)/2, the light which came out from the guide 11 is made to irradiate on the entire light receiving surface uniformly. This means that the minimum light trigger power is always maintained constant within the error range of (b1-a)/2 when a trigger thyristor is assembled. As a result, the assembling work of a light trigger thyristor is simplified, and the irregularity of the minimum light trigger power can be reduced.

Title: Single-sided swash plate type compressor
Inventor: MURAKAMI KAZURO
IPC: F04B27/14
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To suppress any deterioration in the life of a thrust bearing and any increase in its size by reducing the load exerted on it. SOLUTION: The internal pressure of a swash plate chamber 2 is controlled to an intermediate pressure between the discharge pressure and suction pressure to thereby roughly balance the frontward thrust load established by the internal pressure of a cylinder bore 8 and the rearward thrust load established by the internal pressure of the swash plate chamber 2, both exerted on a piston, with each other. This control is realized, by way of example, by the connection of a suction chamber 3b and the swash plate chamber 2 via a regulating valve 20 that works to hold the internal pressure of the swash plate chamber 2 at such a proper intermediate pressure.

Abstract: PURPOSE:To extend the function of a hard disk(HDD) by invalidating an extended ROM on an interface board and using an HDD BIOS in a computer body as an extended ROM at the time of loading the HDD. CONSTITUTION:Since the HDD 121 and a hard disk controller(HDC) 122 are not used when a CPU111 can not confirm the loading of an HDD extended board 123 to an extended slot of a personal computer 11, the extended ROM114 is held at an invalid state by holding a bus 119 at a logically disconnected state.

Abstract: PURPOSE:To make it possible to eliminate vertical chattering of a ribbon core and a ribbon pancake through a simple construction and reduce noise generated at the time of a recording operation, by providing a means for vertically pushing the ribbon core rotatably supported on a shaft in a cassette casing. CONSTITUTION:A cassette casing 1 is usually molded from a plastic, and has a split construction comprising an upper casing 1a and a lower casing 1b.

Title: Charging opening label seal
Inventor: FUJIWARA YASUO
IPC: G03G15/08
Filed: 1992-02-10
Abstract: PURPOSE:To reduce the cost and to automatically perform sealing operation in a short time by sticking two sheets of drawn synthetic paper so that their drawing direction cross each other. CONSTITUTION:The charging opening label seal 1 is formed by sticking two synthetic paper seals 12 each consisting of synthetic paper 10 and an adhesive layer 11. The seal is easy to tear in one direction, but hard to tear in other directions and has extremely high strength in the hard-to-tear directions and never torn even if a grown-up man tries to tear it with all his power. This charging opening label seal 1 is formed by sticking the two synthetic paper seals 12 so that their drawing directions cross each other, for example, at right angles, so the strength is very high in any direction. Therefore, when the charging opening 2 of a developer replenishment container 5 is sealed with the charging opening label seal 1, the seal is strong since the sheets of synthetic paper are stuck so that the drawing directions cross each other, and also tolerant to a shock since the seal is adhered to the peripheral edge of the charging opening.
