Title: Circuit for suppressing dc variation
Inventor: URATA HARUSHIGE
IPC: H04B10/07
Filed: 1983-06-08
Abstract: PURPOSE:To obtain an automatic gain control circuit which can be operated at high speed by amplifying only signal components after detecting and cancelling a DC variation in a DC variation suppressing circuit of an optical signal receiving circuit having a full AGC circuit of the pilot carrier system. CONSTITUTION:The input, where a DC variation Sd accompanied with gain control is added to a signal component Ss, to a light receiving amplifier REC is amplified in amplifier circuits BA1 and BA2. Only the DC variation Sd is extracted by a low-pass filter LPF2 and has the gain adjusted in a polarity inverting circuit INV to have a level equal to that of the DC variation of the output of the amplifier circuit BA1, thus obtaining a polarity-inverted signal. This signal and the output of the amplifier circuit BA2 are added in an adding circuit MIX to eliminate the DC components. Consequently, since the DC variation is eliminated even if the variation Sd of a reverse bias current is mixed with the signal component Ss, low-band oscillation does not occur, and the highspeed operation is possible.

Title: Oxygen concentration controller for oxygen enriching machine
Inventor: TANAKA MINORU
IPC: A62B7/10
Filed: 1989-04-20
Abstract: PURPOSE:To assure the specified minimal air-feeding quantity necessary for maintaining an oxygen concn. so as to enhance air feeding efficiency and to reduce a running cost by providing an air quantity control means which maintains an air feeding rate at the value of a saturation point by decreasing the air quantity of a fan when the air feeding ratio is large and increasing the same when small in accordance with the oxygen concn. characteristics intrinsic to a membrane module. CONSTITUTION:The air quantity control means 6 is connected to the output side interface of an arithmetic section 5 to control the air quantity of the fan 3. The supply air quantity is required to be 20l/min X 20 (value at the saturation point of the air feeding ratio) = 400l/min or above when the oxygen enriching air quantity desired at the present is assumed to be 20l/min. The air quantity control means 6, therefore, operates to maintain the air feeding rate   20 by controlling the speed of a fan motor 14 of the fan 3 so as to lower the rotating speed of the motor when the air feeding rate is large and to conversely raise the speed when the feeding rate is small to prevent the air feeding ratio (V1/V2) from falling below 20. The air feeding efficiency is maintained in the finest state while the required oxygen enriching air quantity is maintained at the specified level by controlling the air quantity in such a manner.

Title: Information recording medium and information recorder
Inventor: TAGAMI KOKI
IPC: G11B7/006
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To prevent the reduction of reliability in data reproduction even if information is repeatedly recorded by performing shifting where a random number J for deciding the lengths of gap and buffer fields is combined with a random number K for deciding the lengths of guord 1 and guord 2 fields. SOLUTION: In recording field, the starting position of an actual recording field excluding gap and buffer fields take one of 16 starting positions by a J valve for deciding the length of the gap field. In addition, a part from guord 1 field to a guord 2 field in an actual recording field moved by this J value is randomly moved by the width of 7 bytes based on a K value. Thus, a position affected by start/end deterioration is decided away as much as possible from a data field. In other words, since the J value is canted by 16 ways and the K value is changed by 8 ways, the head of a VFO field takes one of 128 positions.

Title: Optical node switch
Inventor: HORIMATSU TETSUO
IPC: H04B10/27
Filed: 1982-06-15
Abstract: PURPOSE:To attain the switching of bilateral optical signals having a wide band by diffusing metal on the upper surface of a single plate consisting of an optical crystal substance like a band, connecting plural optical wave guides at plural positions like crosses and forming optical guide type switches on the crossing parts. CONSTITUTION:Optical guide switches 21-26 are formed by the base plate 40, the optical wave guides 41-44 connected like crosses on the upper layer of the base plate 40 and electrodes 46 arranged on respective crossing parts 45 so as to divide the crossing part 45 vertically. The optical wave guides are formed by diffusing titanium or the like by heat treatment, and since the optical wave guides have a larger refractive index than that of the base plate 40, incident light is advanced by repeating full reflection on the inwall surface of each light wave guide. If voltage is applied to the electrode 46, the refractive index of the optical wave guides arranged under the electrode 46 are reduced and light is reflected. Therefore, the incident light goes straight into the wave guide 42 when no voltage is applied to the electrode 46, and when the voltage is applied, the incident light is reflected and its course is switched to the optical wave guide 44. The optical guide switches can be used also as bilateral switches, their crosstalk is low and the switching time is shortened down to the level of 10 seconds.

Title: Electric discharge machine
Inventor: YAMAMOTO MASAHIRO
IPC: B23H1/02
Filed: 1985-05-15
Abstract: PURPOSE:To reduce a floating capacity in a condition that an inter-polar voltage detecting device is connected and enable controlling in accordance with the condition of a part across poles by providing an insulation amplifier which sends out an input signal while maintaining an insulated condition, in the input part of an A/D converter. CONSTITUTION:Voltage from an AC power source 1 to a part across poles is divided by the output side resistor 15 and input side resistors 4, 5 of a rectifying circuit 6, and inputted into a smoothing capacitor 7, a detecting line 3, and an insulation amplifier 14, whose secondary side voltage is inputted into an NC control unit 9 via an A/D converter 8. A floating capacity 11 is hard to be charged due to high resistance value of voltage dividing resistors 4, 5, 15, and is unable to flow back due to the rectifying circuit 6 and, thereby, it is not added to the part across poles 2, while floating capacities 12, 13 are also being separated. Also, the output which has been converted into a DC voltage near the part across poles 2, is not affected by an induction n the detecting line 3, and therefore, if a floating capacity existing in the part across poles 2 is reduced, a minute discharge current can be obtained, improving a surface roughness.

Title: Power source for electric discharge machining
Inventor: MAGARA TAKUJI
IPC: B23H1/02
Filed: 1985-05-15
Abstract: PURPOSE:To obtain a machining power source with a stable output characteristic with respect to variation in floating capacitance, and a good-quality and uniform machining surface by providing a separate power source which adds a voltage in the opposite direction and a switching element for cutting off said separate power source, in a circuit. CONSTITUTION:When the on and off operations of a switching element 2 is repeated at a few MHz by means of a driving circuit 3, a high-frequency AC voltage is generated at a part across poles 6 to carry out electric discharge machining. In the case of an electric discharge device, a floating capacitance 8 varies to a large extent. In principle,however, since a voltage generated between poles 6 depends on the first power source 1 and the second power source 9, the variation in an output voltage with respect to the variation in the floating capacitance 8 is nearly negligible, making the output voltage stable. Thereby, a good-quality and uniform machining surface can always be obtained. And, a tuning system for making a switching frequency variable can be eliminated, supplying a low-cost power source.

Filed: 1982-06-16
Abstract: PURPOSE:To prevent erroneous closing of a main steam sealing valve and suppress stop of a nuclear reactor by installing an air tank and a solenoid valve in a test control circuit, in order to immediately prevent discharge of the air for valve operation when an air pilot valve is broken. CONSTITUTION:In test, a switch C1 is turned ON, when switches C2 and C3 are ON. Then, an air metering valve 4 is opened, and the discharged air is stored in an air tank 2. Since the valve is closed by about 10%, at this time and the internal pressure in the air tank 2 becomes equal to the pressure under a piston 12, a main steam sealing valve is not closed by about 10% or more, even if the air metering valve 4 is in trouble. After test is completed, a test controlling air pilot valve 1 is closed, and a solenoid valve 3 is opened to discharge air. In this case, if the main steam sealing valve is closed by about 10% or more further, the solenoid valve 3 is immediately closed, and thus excessively closed state of the main steam sealing valve can be prevented.
