Title: Magneto-optical overwrite system
Inventor: IWANAGA TOSHIAKI
IPC: G11B11/105
Filed: 1989-03-09
Abstract: PURPOSE:To increase magnetic field intensity generated from a magnetic head, and to overwrite a standardized double-sided disk by generating a high frequency magnetic field at two types of resonance frequencies, and recording the modulation of the frequencies. CONSTITUTION:Based on a synchronous signal inputted from a modulating circuit system 1, a capacitor control circuit 4 changes over capacitors 21 and 22 by a switch 23, and according to a recording information signal, a coil driving circuit 2 switching-superimposes and impresses the two types of the frequencies. Thus a magnetic field modulating coil system 3 constitute two types of resonance tank circuits of an inductor 20 and a capacitor 21 or 22, and the frequency modulation can be recorded at the two types of the frequencies. Consequently the strong high frequency magnetic field can be generated, the magnetic head is remotely set from a medium surface, and the standardized double-sided disk can be used.

Title: Color image forming device
Inventor: TOKIMATSU HIROYUKI
IPC: G03G15/01
Filed: 1995-03-16
Abstract: PURPOSE: To provide a device stably performing electrification for forming electrostatic images classified by colors by plural electrifies respectively and forming a color image excellent in color blance at high speed by impressing voltage on the discharge electrodes of the electrifies from a common constant- current power source through resistances. CONSTITUTION: The constant-current power source 30 is driven from the time a surface where the color image of an image forming body is formed gets in the position of the electrifier 3Y until it finishes getting out the position of the electrifier 3K. In the case a high voltage power source is merely made common in order to simultaneously drive the electrifies 3Y, 3M, 3C and 3K(3Y to 3K), the value of a discharge current flowing to the respective electrifies 3Y to 3K is fluctuated corresponding to image exposure and the state of the developed image forming body. The discharge characteristic is changed and the current value is fluctuated by the staining and the environment of the electrifies 3Y to 3K.  In order to compensate the fluctuation, constant-current control is performed by setting the high voltage power source as the constant- current power source 30, while the discharge is performed by the electrifies 3Y to 3K through the resistances 30Y, 30M, 30C and 30K.

Filed: 1986-03-14
Abstract: PURPOSE:To effect pressure reducing proportional control accurately in a loaded state, by regulating brake pressure applied to a brake actuating unit based on larger and smaller reference reduced speed and presence or absence of generation of a prescribed differential pressure in braking. CONSTITUTION:A pressure confined in a control chamber 17 is increased when a large speed reduction is not made in controlling a start pressure for controlling pressure reduction in a pressure applied to an air over hydraulic booster 5 and a differential pressure between the front and rear of a pressure regulating unit 4 has reached a prescribed value for making up for a shortage of a braking force in accordance with a loaded condition of a vehicle. When a smaller speed reduction is made and no output is produced from a differential pressure sensor 34, the confined pressure is unchanged and a pressure reduction control is effected at the state. With this arrangement, a pressure reduction control can be effected accurately in accordance with a loading condition of a vehicle.

Abstract: PURPOSE:To obtain a device which is silent and almost the same appearance as ordinary style by the hand, by a method wherein an ultrasonic type of motor is used to drive a ring-runner mounted outsidely so as to be freely movable on a rod. CONSTITUTION:A screw shaft (16) is passed through on center axis of a tubing rod (10) and rotated with the rotor of an ultrasonic type of motor (20), since one end of its shaft is supported on a bearing inside a decorative part and the other end of its shaft is connected with the output shaft of the motor (20). When two kinds of high frequency voltage with phase difference are applied on piezoelectric element of the ultrasonic type of motor (20), its rotor and the screw shaft (16) are revolved in one direction, and when the phase difference is reversed, they are revolved in reverse. It is therefore possible to open and close a curtain automatically since a lead ring-runner is moved when the ultrasonic type of motor (20) is controlled. Since the motor (20) is installed inside the tubing rod (10), this device has the same appearance as ordinary style except wiring, and since the motor (20) is silent, no noise is produced.

Abstract: PURPOSE: To detect the content of water stored in a water receiving tank in production of water from atmospheric humidity by a method wherein a spring is placed between this tank and its fixed part so that the tank is displaced by the total amount of the tank and water and the displacement is measured by an displacement meter.  
     CONSTITUTION: A spring 100 placed between a water receive tank 6 and its fixed part 13 causes the tank 6 to be displaced according to the total amount of tank 6 and stored water 6a. A displacement signal corresponding to the displacement is delivered from a displacement meter 101 via an amplifier 102 for the signal. The output signal is detected by a displacement signal detector 103 which provides the above total amount. By preliminarity measuring the weight of the tank 6, the amount of stored water 6a is determined. Thus, the water amount 6a per unit time or water production rate is known so as to give a judgement for the degree of desorption of water adsorbed in adsorbent layer.

Title: Oxygen defficiency safety device
Inventor: SUGANO TADAO
IPC: F23N5/00
Filed: 1984-03-26
Abstract: PURPOSE:To stabilize the action of an oxygen defficiency safety device and to prevent the occurrence of incomplete combustion during low O2 concentration, by a method wherein thermocouples are respectively located in the vicinity of a main burner and a pilot burner, and the theremocouples are connected to each other so that thermoelectromotive forces have reverse polarity to each other. CONSTITUTION:With an ignitor actuated, flame 6 is formed and a thermocouple 9 is heated. Simultaneously, by means of the flame 6, flame is formed at burner ports 21 of a pilot burner 21, and a thermocouple 20 is heated. Pertaining to thermoelectromotive force, generated as a result of each thermocouple being heated, in the case of O2 concentration being 21%, that of the thermocouple 20 is 20mV, and that of the thermocouple 9 is 10mV. In case O2 concentration in atmosphere is decreased under the set condition described above, a decrease in an atmospheric temperature in a combustion chamber 2 is low, and thereby a change in the electromotive force of the thermocouple 9 is low. However, the flame of a pilot burner 21 is extended or lifted up in low O2 concentration atmosphere, and an amount of heat applied on the thermocouple 20 is decreased. This reduces the electromotive force of the thermocouple 20, decreases a difference in an electromotive force between the thermocouples 9 and 20, and as a result, a safety valve 14 is actuated before CO is produced.

Abstract: PURPOSE:To prevent a picture from being again formed in a picture forming surface before the occurrence, by providing a conveyance control means which continually conveys to a paper discharge means a recording medium fed from an intermediate paper-feed/paper-discharge means. CONSTITUTION:If a printer receives picture information from an external device 5, a conveyance control means 6, interprerting the mode select data, outputs to paper feed means 1 a command of feeding recording paper of desired size from any paper feed part of the paper feed means 1. Correspondingly, the recording paper, fed in a predetermined interval, successively forms a picture. While the conveyance control means 6 assigns a conveying direction to a conveying direction control means so that recording paper, fed from an intermediate paper- feed/paper-discharge means 3 for forming a picture in both surfaces, may not be again discharged to the intermediate paper-feed/paper-discharge means 3, and the conveyance control means 6, continually discharging to a paper discharge means 2 the recording paper fed from the means 3, prevents a picture from being again formed before the occurrence. In this way, throughput of the recording paper can be substantially improved.
