Abstract: PURPOSE: To quicken linear calculation in a parallel computer. CONSTITUTION: In a system executing linear-calculation such as the solving of a linear equation system on the parallel computer, a block size LB determined so that paralleling efficiency becomes maximum and a block size MB determined so that the single performance of matrix multiplication is maximum are inputted (processing 13), a matrix is divided into the blocks of a size LB to assign to a processor (processing 14) and an erasing arithmetic part (processing 15) erases a portion of several block stages collectively (processing 21) so as to process erasing arithmetic as the matrix multiplication of the size MB. Both performance of a single processor and paralleling efficiency are improved like this to quicken linear calculation on the parallel computer.

Title: Optical fiber sensor
Inventor: YANO SHINICHI
IPC: G01D21/00
Filed: 1988-12-09
Abstract: PURPOSE:To obtain an optical fiber sensor excellent in linearity, reproducibility and stability by allowing a detecting body whose coefficient of thermal expansion is larger than that of clad to closely adhere to the outer circumferential surface of multi core optical fiber. CONSTITUTION:A detection tube 4 is allowed to closely adhere to the outer circumference of the multi core optical fiber 3. The detection tube 4 is formed of the material whose coefficient of thermal expansion is larger than that of the clad 1 of the multi core optical fiber 3. When the circumferential temperature of the optical fiber sensor rises, the multi core optical fiber 3 is stretched to be always straight because of the large coefficient of expansion of the detection tube 4. Then, the multi core optical fiber 3 is not bent even if the temperature changes. The detection tube 4 is allowed to closely adhere to the clad 1 with epoxy-based adhesive 7. With such a constitution the optical fiber sensor whose characteristic is excellent in the linearity, reproducibility and stability is obtained.

Title: Magneto-optical recording medium
Inventor: SAITO KENGO
IPC: G11B11/105
Filed: 1991-10-31
Abstract: PURPOSE:To enable tracking servo by applying a coating material which is dispersed and kneaded with magnetic powder of hexagonal ferrite together with additives, etc., at need on a substrate, thereby forming the magneto-optical recording medium. CONSTITUTION:After servo signals are written into a magnetic layer 2 for writing the servo signals by using a magnetic head, information signals are written to the magnetic recording layer in accordance with the servo signals. A pair of the servo signals are recorded in the form of the pits along the recording track of data signals and tracking is executed by the output difference between the pit-like servo signals in the case of the servo signals of a generally used sector servo system. The linear servo signals crossing each other are recorded and the positions thereof are known by the timing to capture the linear servo signals in the case of the servo signals of a prior technology servo system. Consequently, the good tracking servo is executed and the reading and writing of the information signals can be executed while the tracking to the recording of a coated type is executed.

Title: Intermittent reception control method
Inventor: KENGAKU AKIHIKO
IPC: H04B7/26
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To eliminate a delay problem of communication start by sending a calling signal in a sending timing in the case of needing to call a radio terminal station and preventing the calling signal from being sent in the case of not needing to call it. SOLUTION: A radio base station A sends a calling signal only when there is a radio terminal station to be called. When a state in which a calling signal does not exist from a called radio terminal station for a fixed time continues after sending a calling signal and it reaches the maximum calling interval, the station A sends a synchronizing signal and synchronizes with the radio terminal station B. On the other hand, the station B starts receiving in an interval of a sending timing and decides the existence a signal when it receives only for a fixed time that corresponds to an initial part of the calling signal and is preliminarily defined. When it decides that the signal exists, it continuously performs receiving and when it is a calling to itself, it returns response to the station A and starts communication. When it decides that the signal does not exist, it stops receiving.

Title: Semiconductor device
Inventor: ISHIGURO MASATO
IPC: H03K3/037
Filed: 1991-11-27
Abstract: PURPOSE:To prevent a meta-stable state by turning on a transmission gate G2 with a delay after a transmission gate G1 is turned off so as to form a period when an input data signal is latched by a master circuit. CONSTITUTION:When a transmission gate (Trm) G1 is turned off, a Trm G2 is turned on and a data signal D at the leading of a clock signal is latched by a master circuit 1. The Trm G2 is still tuned off at this point of time and the inputted signal D is latched only by the master circuit 1 but not outputted. When the input data signal D is in the meta-stable state, the state changes to a stable state for that time. Then the Trm G2 is turned on and the data signal D latched by the master circuit 1 is outputted. Thus, no meta-stable state is caused to the output.

Title: Air conditioner
Inventor: OKI YOSHIBUMI
IPC: F24F11/02
Filed: 1989-12-04
Abstract: PURPOSE:To detect an accurate outside air temperature and improve the accuracy of the control of an air conditioner by accommodating an outside air temperature detecting element in a mirror-finished metallic cylinder, further covering the cylinder by a metallic box with mirror-finished inner surfaces and further providing vent holes between an outdoor unit blower chamber and the metallic box. CONSTITUTION:An air conditioner is composed of an outside air temperature detecting element 4, a metallic cylinder 8, a metallic box 6 with mirror-finished inner surfaces 10, a mounting holder 5 and the vent holes 9 of an outdoor unit outer plate 3 connecting an outdoor unit blower chamber 7 and the metallic box 6 to each other. Since the outside air temperature detecting element 4 reflects infrared rays emitted from other objects and sunlight and the metallic box 6 has the mirror-finished inner surfaces 10, the mirror-finished metallic cylinder 8 reduces the radiation of infrared rays to the cylinder 8. Since the outdoor unit blower chamber 7 has a negative pressure in an operation, the outdoor air is compulsorily drawn toward the chamber 7 via the vent holes 9 formed in the outdoor unit outer plate 3. Thus, the air around the outdoor air temperature detecting element 4 covered by the metallic cylinder 8 is always exchanged with the outside air without an accumulation in the operation.

Filed: 1990-11-19
Abstract: PURPOSE:To obtain a highly reliable thin film EL element with dielectric breakdown nearly made zero even at the time of initial driving by film-making a dielectric layer by an anodic oxidation method. CONSTITUTION:An ITO electrode 2 is made on a glass plate 1, and a Ta thin film is overlapped by a high frequency by the use of a Ta plate and Ar.
