Title: Magnetic recording medium
Inventor: SUGAWARA JUNICHI
IPC: G11B5/70
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To improve the reproduced output by bringing a recording medium into contact with a recording and reproducing device at a high relative speed by specifying the surface average roughness of the magnetic layer applied on a nonmagnetic base to a specific value or below and making a surface distortion value negative as measured by an optical interference type contactless three-dimensional surface roughness gage. SOLUTION: A magnetic coating material is prepd. by mixing and dispersing respectively prescribed pts.wt. of compsns. with and in 100 pts.wt. each of magnetic metallic powder consisting essentially of Fe, toluene, methyl ethyl ketone and cyclohexanone. Such magnetic coating material is applied on a PET film and the surface characteristics of the magnetic layer are controlled by the surface characteristic of calender rolls as well as a treating temp. and pressure under calendering conditions of forming a tape. The surface roughness Ra of the magnetic layer is adjusted to <=6μm and the distortion value Rsk of the surface defined by the equation and measured by the optical interference type contactless three- dimensional surface roughness gage is adjusted to <=0 by such control.  As a result, a good head bearing is obtd. and the reproduced output of low- and high-frequency ranges is improved even when recording and reproducing are executed by bringing the magnetic recording medium and a magnetic recording and reproducing device into contact with each other at a high relative speed.

Title: Optical modulation element
Inventor: KONO KENJI
IPC: G02F1/035
Filed: 1990-02-02
Abstract: PURPOSE:To remove a band limitation due to microwave propagation loss by providing at least one of earth electrode with a slot. CONSTITUTION:The slot 12 is provided at the part of the earth electrode 5 which is nearby a center electrode, i.e. the part where the line of force from the center electrode 4 are concentrated and distributed and the area of the earth electrode 5 is reduced to concentrate the line of force on the part between the gap 11 of the earth electrode 5 and the slot 12. Consequently, the mutual operation between a microwave and light becomes larger and a driving voltage is therefore reducible, so that mutual operation length L required to obtain a desired driving voltage may be short. Consequently, the driving voltage which is applied between the electrodes is reducible and the mutual operation length for obtaining the desired driving voltage can be shortened, so wide-band optical modulation becomes possible.

Abstract: PURPOSE:To obviate erroneous operation in air-fuel ratio feedback control with certainty when an exhaust sensor is inactive, by stopping the air-fuel ratio feedback control as a variation of the exhaust sensor output comes below the specified value. CONSTITUTION:An air-fuel ratio feedback control unit, immediately after O2 sensor output O2 exceeds a slice level SLV (reference value), starts addition of a counter value CNT by a step 1190 when the counter value CNT is discriminated to be not ''-1'' by a step 1185 after carrying out the proportional part reduction process of air-fuel ratio control duty by a step 1180. And, also it discriminates whether the O2 exceeds the value made by adding DELTAV, to the SLV or not by a step 1200 and when the CNT exceeds DELTAt, before exceeding the said value, FBOP is set down to ''0'' by a step 1215 or 1240, stopping the air-fuel feedback control. At a time when the CNT is smaller than the DELTAt, the CNT is reset to ''-1'' by a step 1230.

Abstract: PURPOSE: To properly maintain controls of fuel flow rate in spite of the number of rotation in a gas turbine by providing a means of compensating gains of a regulator to regulate opening degree of a bypass valve juxtaposed to a fuel pump in inverse proportion to the number of rotation in the gas turbine.  
     CONSTITUTION: A fuel controller controls opening degree SBV of a bypass valve 3 by a proportional integral controller 2 so that fuel flow rate signal GL from a fuel flow rate detector 5 can correspond to fuel flow rate demand signal GD from a gas turbine controller 1. Here, additional installation includes a turbine velocity detector 7, and a subtractor 6 to subtract fuel flow rate deviating signal ΔG from output of this detector 7. And opening degree of the bypass valve 3 is controlled by output of the controller 2 in response to output of the subtractor 6. By doing so, gains of opening degree control in a split valve 3 compensate ΔG which is input of the controller 2 so as to be inversely proportional to the number of rotation in the turbine, to constantly stabilize loop gains.

Title: Temperature measuring circuit
Inventor: JINGUU TOSHIKO
IPC: G01K1/02
Filed: 1983-02-15
Abstract: PURPOSE:To enable measurement of a temp. from the time when an FF is set in accordance with the time constant of an integrating circuit by constituting the integrating circuit of a resistor having the resistance value changing with temp. and a capacitor, and connecting the output therefrom to the input terminal of the FF. CONSTITUTION:The value of the measurement time with the 1st counter is divided by the value of the measurement time with the 2nd counter in a CPU and the divided value is inputted to the 3rd counter. The value entering the 3rd counter is the coefft. of a temp. and the degree of the temp. measured with a thermistor RT is known by comparing said value with the value stored preliminarily in the CPU. The capacitor and RS-FF used for measuring the RT and Rr are commonly used, by which the number of parts is reduced and the error owing to the variance in the characteristics of the parts is minimized. Although noise is easily entrainable in the lead part (l) of the thermistor RT, some noise is absorbed in the capacitor and the RS-FF when once reset does not give the influence of noise on the output side and therefore the error by the noise is decreased as well.

IPC: G02B26/10
Filed: 1975-02-25
Abstract: A compact flatbed page scanner for facsimile transmission is described. The apparatus uses a linear charge coupled imaging device (CCID) for both light detection and electronic scanning across the width of the page. Compactness is achieved by folding the optical path from the scanned line to the CCID. A moving carriage below a horizontal glass plate supporting the document to be scanned carries: the linear CCID, a lens for focusing an image of one scanning line of the page onto the CCID, an assembly of bar mirrors for folding the path of the light beam from the scanning line to the lens, and tubular lamps for illuminating the scanning line. The motion of the carriage beneath the horizontal glass plate permits scanning an array of parallel lines, equally spaced over the length of the page. In the apparatus described, scanning a complete page may be performed from 4 seconds to several minutes, depending on the bandwidth available for transmission.
