Title: Charged facsimile receiver
Inventor: MARUYAMA YUUJI
IPC: H04N1/34
Filed: 1979-02-20
Abstract: PURPOSE: To eliminate the defect as well as prevent the surreptitious use for the card by securing the operation of the device with insertion of the card incorporating the same electronic circuit as the partial circuit of the main body of the facsimile receiver.  
     CONSTITUTION: With insertion of card 1 incorporating electronic circuit 2 into the main body, the connection is secured to the circuit within the main body via terminals 3, 4 and 8 each. Electronic circuit 6 within the main body features the same constitution as circuit 2, and generates the same output to the same input given from terminal 5. The output is compared through comparator 7 between circuits 2 and 6, and the coincidence signal is supplied to memory circuit 10 comprising set/reset FF and RSFF and others to hold the set state. Then the output of circuit 10 is supplied to counter circuit 11 which decides the working period of the device to be turned into the trigger signal for starting of the counting. Circuit 11 generates the set signal and supplies the signal to the relay from terminal 14 via amplifier 13 and in the form of the control signal, thus giving the control to the motor, the power source and the like. And when circuit 11 completes the counting along with the output inversion, the RSFF of circuit 10 is reset to stop the counting action. At the same time, the inverted signal stops the function of circuit 2 to avoid the reuse of the card.

Title: Card reader controller
Inventor: MORINOUCHI KINYA
IPC: G06K13/067
Filed: 1984-02-03
Abstract: PURPOSE:To report abnormal running of a card with sound by providing additionally a means which measures the time of intervals of a clock signal led out from a card reader. CONSTITUTION:When the card is inserted to an MCR card reader 1, reading operation of contents of the card is started, and the clock signal is outputted from the card reader 1 in accordance with this reading operation. The time of intervals of this outputted clock signal is measured, and a maximum counted value (in case of the lowest running speed of the card) and a minimum counted value are stored in buffers TMAX and TMIN respectively. The lower limit value of the card speed which is preliminarily stored in a memory area MMAX is compared with contents in said buffer TMAX, and a high-pitched tone buzzer is sounded in case of MMAX<TMAX; and the upper limit value of the card speed which is preliminarily stored in a memory area MMIN is compared with contents in said buffer TMIN, and a low-pitched tone buzzer is sounded in case of MMIN>TMIN, and thus, abnormality is reported to an operator.

Title: Variable-speed blower control device for prevention of surging
Inventor: FUKUSHIMA SHIYUN
IPC: F04D27/02
Filed: 1980-02-20
Abstract: PURPOSE: To reduce frequence of operating a suction valve and stabilize the work of a variable-speed blower by adjusting the opening of suction valve in steps in accordance with the blowing amount from the blower as well as by giving hysteresis with a certain width to the preset value of the blowing amount for the change-over point of opening of the suction valve.  
     CONSTITUTION: A speed sensing oscillator 21 senses off the revolving speed of a blower 11 and sends commands to two interlocked switches 17, 18 if the sensed speed is the No.1 speed, to let these switches make contact with a contact point (a), and changes over these to another contact point b if the sensed speed is the No.2 speed. The switches 17, 18 are thus arranged to be set to the terminal 11 if the sensed speed is the n'th speed. Combinations of the set comparators 16, 16... with an opening command device 14 are furnished in a number of n (S 0 WS n ), and each combination is given a setting value of blowing amount for the change- over point of the opening of suction valve (damper) 12 provided with a hysteresis having a certain width. Accordingly, the frequence of operating the suction valve 12 decreases and its work is stabilized.

Abstract: PURPOSE:To render the exfoliation of thermion emission body powder not to be generated, by coating a cathode substrate with a nickel porous layer having sponge-like continuous three-demensional structure, and further coating the differential gap or the surface of said body with the oxide of alkaline earth metals. CONSTITUTION:Urethane foaming resin with a desired porosity is dipped into a carbon powder-despersed solution in order to coat the resin surface with carbon film, then said resin is subjected to a conductive treatment. Nickel coating is conducted thereon by electroplating, thereafter the carbon and the resin are forced to evaporate by a heat treatment. In this manner, the nickel porous body attached to the cathode substrate is thick, whose thickness is 2-5mm.. Therefore, said porous body is impregnated with acryl resin, and then it is cut by lathe up to 0.1-0.2mm.. Thereafter, said acryl resin is removed by the use of a solvent such as acetone, again said porous body is subjected to a heat-treatment in the wet hydrogen atmosphere at 950 deg.C for 30min. Next, thus manufactured cathode substrate is welded to a sleeve which accommodates a heater, then said substrate is applicated with (Ba, Ca, Sr) CO by spraying method, and subjected to ordinary decomposition and activity process in order to form an oxide, thus said cathode is obtained.

Title: Steering wheel restoration control device for electric power steering
Inventor: ABE TSUKASA
IPC: B62D101/00
Filed: 1992-02-05
Abstract: PURPOSE:To allow the steering wheel returning operation of a driver with an equal steering feeling regardless of an outside temperature, high or low. CONSTITUTION:A temperature sensor 35 detects an outside temperature. A microcomputer 33 outputs a control signal to an electric motor 22 to control output torque greater at a low outside temperature than at a high outside temperature. The rotation of the electric motor 22 is transmitted to a steering shaft 12 via a small gear 23 and a large gear 21 to assist a steering wheel 11 in returning. As a result, even if an outside temperature is low, the viscosity of oil filled up in and around the shaft 22a of the electric motor 22 and the small and large gears 21, 23 is high and part of the output torque of the motor 22 is wasted with the oil, driving force transmitted from the motor 22 to the steering shaft 12 is equal to that at a high outside temperature, so that the steering wheel can be assisted in returning with equal force regardless of an outside temperature, high or low.

Filed: 1994-02-17
Abstract: PURPOSE:To completely detect a failure in sealing by placing a plurality of load detectors along seal widthwise and lengthwise directions inside at least one of seal bars placed oppositely across a film. CONSTITUTION:A seal bar 60 has respective sealing parts 60a to 60f separately and slidably placed. Load detecting parts 70a to 70f are provided on the respective sealing parts 60a to 60f, wherein a load detector 70 comprising a high temperature distortion gage is attached to this part for detecting a load. The respective bars 60a to 60f are fixed to a holding plate 65 by a bolt 71 and set in a holder 51, while a heater 56 and a heat pipe 55 are buried in the holder 51. The load detecting parts 70a to 70f are placed at three positions along a widthwise direction. Therefore, since the load detector 70 detects an increase in the load independently corresponding to even a very small foreign material engaged only into each part on the respective sealing parts, normal determination can be made except when the foreign materials are engaged into the three positions at the same time.
