Patent JP-H02206036-A (JP)
Title: Optical head device
Inventor: YAMANAKA YUTAKA
IPC: G11B7/13
Filed: 1989-02-03
Abstract: PURPOSE:To obtain a signal detection system where a reproduced signal is less degraded by allowing the main lobe component of a spot condensed again to mainly include the reflected light from the main lobe on a recording medium. CONSTITUTION:The light emitted from a semiconductor laser 1 passes a collimator lens 2, a light shielding band 3, and beam splitters 4-1 and 4-2 to form a super-resolution spot on a recording medium 6 by a condensing lens 5. The reflected light from this spot is divided into two by splitters, and one forms a spot on a divided photodetector 8 by a converging lens 7, and the other is led to an error detecting optical system 9. A main spot 10 is formed on a detecting part 14 of the detector 8, and two side spots 11 are formed on detecting parts 15 and 16 of the detector 8, and a detection signal (a) of the detecting part 14 and a detection signal (b) of detecting parts 15 and 16 are obtained. The reflected light from the main lobe on the recording medium is mainly included in the main lobe component of this spot condensed again. Consequently, the reproduced signal of less passing-round from side lobes is obtained by the signal (a).

Title: Flow rate control method
Inventor: MIZOGUCHI YOSHITOMO
IPC: G05D7/06
Filed: 1984-02-16
Abstract: PURPOSE:To attain the stable control of flow rate even in case the number of working pumps is changed by obtaining the control output time width and the control output pause time width in order to give the intermittent control to a discharge valve having a selected short target arriving time. CONSTITUTION:In case the number of working pumps is changed, a comparison is carried out between a period of time during which the opening amount of a discharge valve that is operated continuously is coincident with the target opening amount of the discharge valve set after the number of working pumps is changed and a period during which a discharge valve of a pump to be operated newly reaches said target opening amount or a period during which the discharge valve of a pump whose operation is stopped is closed. Thus the discharge valve having the shorter time to reach the target opening amount is selected. At the same time, the difference is obtained between both reaching times. Then the control output time width is obtained from the selected reaching time of the discharge valve and the intermittent control times set previously. While the control output puase time width is obtained from said time difference and intermittent control times. Then the intermittent control is given to the discharge valve having the selected short reaching time. In this way, a big variation of the total discharge amount is prevented.

Abstract: PROBLEM TO BE SOLVED: To reduce the time for connection and to reduce a connection deciding function on the side of a device to be connected by omitting decision of connection when optional connection decision is executed before the decision. SOLUTION: In order to authenticate by an authentication device 13 at the time of connecting a communication terminal equipment 7 or a communication terminal equipment 9 consisting of a communication terminal 9a and a portable terminal 9b to an equipment to be connected 11, the device 13 executes connection decision to decide the normal/defective condition of connection. Communication decided to be defective is interrupted by the device 13. On the other hand, concerning communication decided to be normal by this decision, a first-kind communications company side installing the equipment 11 changes a connecting destination to the equipment 11 at need.  Though authentication decision to the equipment 11 is executed by a software for connection provided for the equipments 7 and 9, this authentication has already been decided to be normal by the device 13, therefore connection decision in the equipment 11 is omitted.

IPC: G06F17/50
Filed: 1992-01-17
Abstract: PURPOSE:To automate wiring between plural terminals and to simplify wiring work by successively specifying one output side circuit symbol or more and one input side circuit symbol or more displayed on a display device. CONSTITUTION:In the case of mutually connecting the terminals of plural circuit symbols, the circuit symbols to be wired is displayed and arranged on a CRT screen and then an automatic wiring mode is set up. When the arranged output side circuit symbols 21 and the arranged input side circuit symbols 22 are successively specified and selected by means of a symbol selecting mark A, the X coordinates of the output terminals 21o1 to 21o10 of the symbols 21 are compared with that of the input terminals 22i1 to 22i10 of the symbols 22 and the terminals of the same X coordinate are mutually connected through a wire 23. Since both of the X and Y coordinates of the output terminal 21o7 and the input terminal 22i7 are mutually different, automatic wiring is not executed. The parts are wired by a convensional method for picking up them by a mouse.
