Title: Differential pressure transmitter
Inventor: MASUDA HISAYOSHI
IPC: G01L13/02
Filed: 1980-12-26
Abstract: PURPOSE:To realize a differential pressure transmitter of a simple constitution which is free from any zero point error caused by the static pressure, by providing an elastic member into a low-pressure or high-pressure chamber with the intervention of air in order to ensure a free adjustment for the displacement of a diaphragm. CONSTITUTION:When the pressure in a low-pressure chamber 51 is increased with application of the static pressure, a circular metallic plate 10 provided in the chamber 51 with the intervention of air bends toward the air. As a result, a diaphragm 21 for partition of liquid bends toward the chamber 51. Accordingly, the pressure in the chamber 51 is equal to the value obtained by subtracting the pressure corresponding to the displacement of the diaphragm 21 from the pressure at the pressure lead-in port 81. Thus the zero point error caused by the static pressure becomes substantially to zero. The same result is obtained when the plate 10 is provided in a high-pressure chamber or in both the high-pressure and low-pressure chambers. Thus no difference exists among the component parts to eliminate the precision process. Furthermore, the free adjustment is possible after assembly. As a result, the differential pressure transmitter is formed with a simple constitution with no zero point error caused by the static pressure.

Abstract: PURPOSE: To facilitate the restarting of an engine, by completely closing a throttle valve of a carbureter after the engine has been stopped, and thereafter opening the throttle valve to the idling opening.  
     CONSTITUTION: When a signal (a) of an ignition switch 116 changes from a high level to a low level, an output (b) of an inverter 131 becomes high, and is inputted into a delay circuit 122, and after about 10sec. after the output of a return signal (A), it is set to rise so that the engine 1 is positively stopped. When the output (e) of a buffer 134 rises, a one-shot multivibrator 123 outputs a high level signal (f) for an interval t 3  to open and AND gate 139. Therefore the AND gate outputs a pulse wave (g) from an oscillator 124 for a periof of t 3 , and this pulse wave (g) becomes a projection signal (B). By this projection signal (B) the throttle valve is opened to the idling opening.

Filed: 1993-06-30
Abstract: PURPOSE:To provide a power-supply circuit for a hybrid vehicle driving an engine in the vicinity of a maximum efficiency point and lowering exhaust gas while preventing the deterioration of a battery. CONSTITUTION:A control section 21 detects the state of the travelling stoppage of a vehicle from a vehicle speed signal and a shift position signal transmitted from a sensor section 27. When the quantity of a battery charged reaches a specified value or less at that time, an engine 11 is driven in the vicinity of a maximum efficiency point A and power is generated by a generating set 13, and power is charged until the capacity of a capacitor 15 reaches a fixed value (the state of approximately full charging). When power is charged until the capacity of the capacitor 15 reaches the fixed value, the control section 21 stops the driving of the engine 11 when the state of travelling stoppage is completed. The control section 21 charges the battery 17 with electricity from the capacitor 15 by the connection of a switch 25, and the control section 21 returns the switch to an original state when charging is completed.

Abstract: PURPOSE:To raise the voltage of an X-ray tube quickly by adjusting, before X- ray exposure, the peak value of the output voltage of an AC-DC converter to be the same as a preset value of the input voltage of an inverter and adjusting, during the exposure, the mean value of the output voltage to be the same as the preset value. CONSTITUTION:An a.c. power source 1, after being controlled in its phase by means of an AC-DC converter 2, is supplied as a d.c. power source to an inverter 5 through a smoothing circuit 3. The input voltage of the inverter 5 is set by the converter 2 controlled by an AC-DC conversion controller 10 having as inputs both an actual value of the input voltage of the inverter 5 sent from a voltage divider 4 and a preset value of the output of an X-ray tube. When an X-ray exposure signal is fed to the input of an inverter controller 11, the inverter 5 starts to operate at a preset frequency or electrified width, electric power is supplied to a high-voltage transformer 6, and an X-ray tube 9 is put to work through a rectifier 7 and a capacitor 8. The controller 10 is set for the peak value of the output voltage of the converter 2 before X-ray exposure and for the mean value during the exposure. As a result, the voltage of the X-ray tube 9 can be raised quickly.

Title: Exposing device for image forming device
Inventor: OKU HIROMICHI
IPC: G03G15/043
Filed: 1990-07-16
Abstract: PURPOSE:To prevent toner from adhering to the emitting part of an exposing part or an inside optical system by providing a pair of electrodes arranged to be opposed by putting an optical path between them near the emitting side of the exposing part and connected to a power source so that a potential difference between them may be set. CONSTITUTION:A pair of plate electrodes 5 and 6 opposed by putting the optical path between them is disposed near a condensing lens 4. The electrodes 5 and 6 are connected to the anode and the cathode of the power source 7, respectively. By irradiating the electrostatically charged part of an image carrier 1 with an optical signal from the exposing part 2, an electrostatic latent image is formed and developed by a developing part 3. Since the image carrier 1 is rotated at a high speed at such a time, the toner adhering to the outer periphery of the image carrier 1 is scattered and suspended in the circumference. The suspended toner 8, whose polarity is unstable, is attracted to the electrode 5 or 6 having the different polarity. By sticking an adhesive tape to the electrodes 5 and 6, the suspended toner 8 attracted to the electrodes 5 or 6 is kept in a state where it is captured by the adhesive tape even after the charge of the toner 8 is neutralized.

Title: Locking system of storage device access
Inventor: INOUE KOUICHI
IPC: G06F21/62
Filed: 1980-12-29
Abstract: PURPOSE:To minimize the interruption of access caused by a locking instruction given from a program of another CPU, by using plural processors having buffer storage devices of store through system. CONSTITUTION:In case an access is given to a common region 18 by a program of a CPU11 by means of a locking instruction, the information of a CPU13 is set to a flip-flop circuit and the corresponding data is transferred onto a buffer storage 14. When the CPU11 releases its locking, the contents of the storage 14 corresponding to the address is made ineffective at a CPU18 by a BIC15. Then a locking request is given again when an identification word 16 is fetched from the CPU18. Thus the word 16 is fetched from a main memory 17 with no use of the storage 14, and then set to show that the lock is obtained by itself.

Abstract: PURPOSE:To prevent input of an excessive stress to a damping device connected to a frame and hold the damping device in a sound state. CONSTITUTION:A damping frame comprises a high rigid frame 2 of rigid frame structure having one end joined in a rigid manner with a frame 4 and assembled within the surface of the frame 4 and a shearing yield member 3 having one end joined in a rigid manner with the high rigid frame 2 and protruded from the high rigid frame 2 toward the damping device 5 side and the other end connected to the damping device 5 and formed of a shearing yield member 3 having strength lower than that of the rigid frame 2. An earthquake resisting device is burdened with a horizontal force transmitted from the damping device 5 during in-plane deformation of the frame 4. By setting a horizontal bearing force, determined based on the yield bearing force of a shearing yield member 3, to a value lower than the allowable bearing force of the damping device 5, the shearing yield member 3 is yielded by a load lower than the bearing force of the damping device 5 in a state that it is burdened with a horizontal force when an excessive horizontal force is exerted, and an input of a load exceeding an allowable bearing force on the damping device 5 is prevented from occurring.
