Patent JP-S5831427-A (JP)
Title: Synchronous circuit for plural switching regulators
Inventor: IWASA SADAYUKI
IPC: H02M3/28
Filed: 1981-08-19
Abstract: PURPOSE:To prevent each switching regulator unit from mutual frequency interference and reducde the number of parts by connecting a photocoupler between a main switching regulator unit and other switching regulator units. CONSTITUTION:If the output voltage of a switching regulator unit 10 is raised higher than the set voltage, an error amplifier 11 is actuated to amplify the rising or dropping error from the set voltage of the unit 10 and the amplified error signal is sent to a comparator 12. The comparator 12 compares the amplified error signal with a standard triangular wave signal from a triangular wave generator 50 and actuates a switching circuit 13 to drop or raise the output voltage and return the output voltage to the set voltage. When the output voltage of a switching regulator unit 20 is raised or dropped, a photocoupler 70 transmits a triangular wave signal from an amplifier 60 to a comparator 22 in the switching regulator unit 20 and the same operation as said procedure is carried out.

Title: Freezing machine
Inventor: NISHIDA OSAMU
IPC: F25D17/02
Filed: 1977-11-02
Abstract: PURPOSE: To prevent the deterioration of heat exchange efficiency and control corrosion, by fitting a water treatment device upstream a heat exchanger in the cooling water cycle.  
     CONSTITUTION: Cooling water for cooling a condenser flows from the cooling water passage 1 into a water treatment device 2 where it undergoes treatment while passing through an activated alumina tank 2a, activated charcoal tank 2b and cation exchange resin tank 2c. The water then gets mixed with a pasteurizing agent generated by a pasteurizer generator 10 in an injector 9 and flows in the condenser through a passage 7. This system makes the condenser free from scale and corrosion.

IPC: G03G15/08
Filed: 1982-07-27
Abstract: PURPOSE:To improve the stability in the result of development in a developing method which scatters a toner onto the surface of a latent image holding body, by providing the 2nd magnet and correcting the charge on the surface of a developing roll. CONSTITUTION:A magnet roll 4 which supplies a thin toner layer on the surface of a high insulation layer 3 in contact with said layer and the 2nd magnet 5 are provided. A DC bias by a power source 8 and an AC voltage by a power source 7 are applied to the roll 4, and a DC bias by a power source 9 and an AC voltage by a power source 7 are applied to the magnet 5. The DC bias exactly reversed from the bias applied between the roll 4 and a developing roll 2 is applied on the magnet 5. In other words, the biases are so set that minus charge is injected onto the surface of the roll 2 during operation. The formation of the uniform thin layer of the toner is thus made possible, and the stability in the result of the development is improved.

IPC: G03G15/14
Filed: 1989-05-24
Abstract: PURPOSE:To prevent the variation of carrier tension caused by the change of paper width by electrostatically attracting a recording paper to an endless belt and carrying it out. CONSTITUTION:A visible image is transferred on the recording paper 6 which is fed at a constant speed in the direction of an arrow by a tractor means 11 in a transfer part 5. The transfer is performed by utilizing electrostatic force by the electrostatic charge of the endless belt 18 of an endless belt means 20 which is electrostatically charged by an electrostatic charger 19. At the same time, the recording paper 6 is electrostatically attracted by the endless belt 18 charged with the electrostatic charge and carried out, then it is submitted to fixation by a fixing device 7. Since the recording paper 6 is electrostatically attracted by the endless belt 18, it is made to slide. Therefore, the recording paper 6 is carried out while the overfeeding amount of the recording paper 6 is always corrected.

Title: Level control valve
Inventor: FUJIWARA KATSUJI
IPC: F16K31/34
Filed: 1979-10-11
Abstract: PURPOSE: To provide a belt control valve for adjustably supplying or stopping water to a tank according to the water level in the tank by opening and closing an opening of a pilot valve with a float to control pressure in a pressure changing chamber for driving a pressure responsive main valve.  
     CONSTITUTION: Water introduced into an inlet 11 passes through an inlet path 12 and outlet path 16 to be supplied to a tank through an outlet 15. As the water supply proceeds, water level in the tank rises. Thus, water level in a skirt 6 rises to float a float 5 which closes an opening 21 of a pilot valve at a seat surface 25  with buoyancy. Hence, water flow from the inlet path 12 to the outlet path 16 is  shut off. Next, the water level in the tank is lowered as water is consumed and the float 5 falls to open the pilot valve 21 and resume the water supply. Only by removing either of blind plugs 33A, 33B and 33C can be adjusted the water level from which the water supply is started.

When the player steps on the accelerator 8 in this state, the scene is continuously changed. When a handle 5 is rotated clockwise or counterclockwise during running, a vehicle body 4 is turned to a base 2 in the rotating direction of the handle 5. The scene displayed on the scene display device 6 is moved in the direction opposite to the rotating direction of the handle 5. Thus, the vehicle body is driven as if it were running in the scene displayed on the scene display device 6 while describing a curve. When a turbo button 11 provided on a dashboard 10 in the front of the vehicle body 4 is depressed, a turbo tone is emitted and the changing speed of the scene is increased. The weight is moved (eccentrically rotated) in the vehicle body to oscillate the vehicle body 4.

Title: Photosensitive responding device
Inventor: SHIOZAWA KAZUO
IPC: G03B7/08
Filed: 1979-10-12
Abstract: PURPOSE:To make a circuit operate in a simple and stable manner by a constitution wherein a pulse generating device is controlled by the output of a comparing device whose input is obtained from the output of a delay device connected to the output of a photoelectric photometrical device and from the output of the photoelectric photometrical device. CONSTITUTION:A switch S1' is turned on in linkage to a switch S. The output P of a photometrical circuit Ph is transduced into a signal P' through a connector Cn and the latter is inputted in a comparator A4 through an amplifier A1, a delay circuit D, switch contacts (a) and (b) and an operational amplifier A3. In the case of a camera, for instance, a contacting piece is connected to the side of (a) and (b) when the light intensity of an object changes from strong to weak, while it is connected to the side of (c) and (d) when the change is contrary. The comparator A4 compares the input with the prescribed voltage VR, and when the input is larger than the voltage, it turns inverse and makes a controlling device Co operate for exposure through the intermediary of one-shot multiplier OM, TR1 and TR2. When the piece is switched on the side of (c) and (d), the exposure is performed without being delayed. By this constitution, the stable operation can be performed with the simple structure.
