Title: Vibration isolation device
Inventor: FUKUDA YUTAKA
IPC: E04H9/02
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To reduce manufacturing cost by simple structure, and to curtail cost largely though the vibration isolation device has a vibration isolation effect in the same extent as a laminated-rubber bearing by burying a coil spring along the periphery of a rubber block. SOLUTION: Flanges 2 connecting a building and a foundation and being made of iron are installed at both ends of a rubber block 1 formed of a natural rubber or a high damping rubber, and coil springs 3 having diameters smaller than the rubber block 1 are buried along the periphery of the rubber block 1. The coil springs 3 are inserted into a mold in the rubber block 1, a raw material rubber is poured in and heat and pressure are applied, and the coil springs 3 and the raw material rubber are molded integrally. The flanges 2 are valcanized and bonded with the rubber block 1 by applying heat and pressure. The vibration isolation device is installed at a place required in a building and a work such as a section between the foundation and a column on a lowermost floor.  The rubber block 1 intends to be protruded laterally by the vertical load of the column at that time, but the protrusion of the rubber block 1 is constrained by the coil springs 3 and the shape of the rubber block 1 is held.

Title: Character input control system for character graphic processor
Inventor: TOKITA KEIKO
IPC: G06F3/153
Filed: 1989-03-08
Abstract: PURPOSE:To attain the highly efficient input of characters by setting dynamically an echo area and at the same time setting fine character sizes in the echo area. CONSTITUTION:An echo area set-up request is given to a system processor SP 1 from an input/output-only processor PP 2 at a time point when the first character to be read is inputted. Thus an echo area is set up based on an instruction of the SP 1. In this case, an echo area range can be designated together with the echo start and end positions. At the same time, the prescribed attributes related to characters including the height, the width ratio, and the space of input characters are given as parameters. Thus the highly efficient input is attained for characters.

Title: Track retrieving device
Inventor: YAMAGUCHI HIROYUKI
IPC: G11B21/08
Filed: 1989-03-07
Abstract: PURPOSE:To prevent the rapid deceleration of optical beam caused by the erroneous detection of optical beam velocity and to enable stable track retrieval by executing velocity detection again when the erroneous detection of the velocity occurs. CONSTITUTION:A microcomputer 26 calculates the detected velocity of the optical beam based on the measured value of a timer 20. Command velocity is calculated based on the count value of a counter 25. Next, when the count value of the counter is larger than a prescribed value, difference between the detected velocity of the optical beam and command velocity is calculated by the microcomputer 26 and outputted to a D/A converter 33. The track retrieval is started based on this output. When the erroneous detection of the velocity occurs by the drop out of a disk or the noise of an equipment, the microcomputer 26 does not execute the calculation of the output value to the D/A converter 33 but executes the velocity detection again. As a result, since the output value to the D/A converter 33 is calculated, the rapid deceleration of the optical beam can be prevented.

Filed: 1989-03-08
Abstract: PURPOSE:To improve reliability by utilizing the change in an output signal which is outputted from a temperature detecting terminal on the basis of the difference of temperature characteristics between a 1st and a 2nd detecting elements and obtaining a detected temperature as the boundary temperature of the 2nd detecting element. CONSTITUTION:An NTC thermistor 4 has the negative temperature characteristic in a fixed temperature range. And a V type thermistor 6, where a specified temperature To in the fixed temperature range is regarded as the boundary, has the negative temperature characteristic of a low temperature side area corresponding to the thermistor 4, and has the positive temperature characteristic on the side where the temperature is higher than the temperature To. Such a temperature detector 1 is arranged, for example, near the heat generating part of an air conditioning equipment and a prescribed voltage Vcc is supplied between lead wires 7a and 7b. In the temperature range where the temperature of the thermistor 4 or 6 is lower than the temperature To, the ratio between the impedance of the thermistor 6 and the whole impedance of the thermistor 4 or 6 is always fixed. Contrarily, in the temperature range where the temperature of the thermistor 4 or 6 is higher than the temperature To, the ratio is rapidly increased on the basis of the temperature characteristic of the thermistor 6. Thus, the temperature control for the air conditioning equipment can be performed by detecting the output signal V01.
