IPC: H02N2/00
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To ideally drive all vibration actuator, even when one vibration actuator or a plurality of vibration actuators are selectively driven. SOLUTION: When a vibration actuator 50i to be driven is selected though a switch circuit 12, the frequency of an AC signal being applied to the vibration actuator 50I by a driving circuit 1 is swept from a high-frequency side to a low-frequency side. During the sweep, the current value of current for drive is detected by a detection circuit 18. Then, a control device 22 monitors a detection value being detected by the detection circuit 18, the sweep of a drive frequency is stopped at either point of time between the point of time, when a parameter value being related to the detection value becomes a specified value and the point of time when the frequency is swept by a specific frequency. After that, the vibration actuator 50i is driven by the AC signal of the driving frequency, at the point of time when the frequency sweep is stopped.

IPC: G01N21/75
Filed: 1988-12-13
Abstract: PURPOSE:To prepare an accurate calibration curve by spotting a reference liquid for calibration on a reference inspection object and an object to be inspected to determine a characteristic value for calibration. CONSTITUTION:A reference liquid for calibration such as a body fluid of animal with characteristic constant and adjusted in components is prepared and spotted on a reference test film to determine an optical reflection density D1 with a reference analyzer. Then, a reference liquid for calibration is spotted on an object test film to determine an optical reflection density D2 with the reference analyzer. A ratio of D2/D1 is recorded on a wound cassette 16 of the object test film in a bar code 16c as characteristic value per lot to be provided to a user. Then, when the user sets the object test film on an analyzer, the bar code 16c is read out, a calibration curve calibrating circuit 73 inputs the characteristic value and a reference calibration curve (solid line) inputted from a calibration memory means 74 is multiplied by the ratio D2/D1 to determine a calibration curve (broken line), which is inputted into a material density computing circuit 72. Thus, it is suffice to use only one kind of reference liquid for calibration and moreover, accuracy of calibration can be maintained.

Title: Noistureproofing storage chamber
Inventor: SAITO KAZUHIKO
IPC: F26B21/00
Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To continuously adsorb moisture in a chamber body by bringing hydrogen ion separation means having a hydrogen ion conductor film into contact with an adsorbent in order to release moisture adsorbed by the adsorbent to the outside of a moistureproofing storage chamber body. SOLUTION: Provided air in a chamber body 1 is circulated through an adsorbent 15 with circulation means 17, moisture in the chamber body 1 is adsorbed and accumulated in the adsorbent 15 to lower the moisture in the chamber body 1. In contrast, the adsorbent 15 adsorbs the moisture and hence moistening action is gradually deteriorated. However, a decomposition reaction: H2 O→2H<+> +(1/2)O2 +2e<-> is produced at an interface between a hydrogen ion conductor film 20 and porous electrodes 21a, 21b owing to application of voltage to hydrogen ion separation means 19, and oxygen O2 produced by the decomposition is left behind in the chamber body 1 while hydrogen H2 is discharged as gas to the outside of the chamber body 1.  As a result, the moisture in the moisture adsorbent 15 is continuously discharged to the outside of the chamber body 1, and hence moisture adsorption is prevented from being deteriorated.

Patent JP-H09185900-A (JP)
Title: Dynamic ram
Inventor: MIYAZAWA KAZUYUKI
IPC: G11C29/00
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To shorten test time by testing in plural bits without increasing the number of external terminals. SOLUTION: A test mode is set by making the combination of external control signals (row address strobe signal RASUB, column address strobe signal CASUB and write enable signal WEUB) different from the case of a normal mode without providing a test exclusive terminal. That is, the test mode is set by discriminating that the column address strobe signal CASUB and the write enable signal WEUB are made a low level at the fall timing of the row address strobe signal RASUB. Further, coincidence/noncoincidence of a read-out signal constituted of plural bits is detected, and an output signal according to its detected output is sent to the external terminal, and the test is performed. Thus, the test exclusive terminal is eliminated, and mounting density of a package of a large capacity memory is improved, and the test time is shortened.

Abstract: PURPOSE:To rapidly perform shape correction by forming a support roll on one side so that the interval between separated rolls can be adjusted with a hydraulic driving means and forming a pair of support rolls on the other side so that the interval between separated rolls can be adjusted with a hydraulic driving means. CONSTITUTION:The position movement of the separated support rolls 34 is done by expanding/contracting motion of rods of the hydraulic driving means in an upper back-up roll 28 and the clearance between the separated rolls is adjusted. On the other hand, it is done by opening/closing straddle links which follow the expanding/contracting motion of the rod of a hydraulic driving means of a lower back-up roll 30 and the interval between a pair of separated rolls 38 is adjusted. Then, the fulcrum of roll bending due to the separated support rolls is changed with each hydraulic driving means of the upper and lower back-up rolls and roll bending can be rapidly adjusted by pressurizing force with a pressurizing means between the bearings of work rolls independently or cooperatively. In this way, crown control in high-speed rolling is accurately performed and proper position control with high adaptation is possible.
