Title: Plane display device
Inventor: KOMIYA RYOHEI
IPC: H01J31/15
Filed: 1986-04-10
Abstract: PURPOSE:To obtain a plane display device being equal to that of a CRT in quality by using a phosphor screen by providing around a cathode performing thermal electron emission a plural number of electrodes for emitting secondary electrons of higher potential than said cathode. CONSTITUTION:Plural pieces of linear cathodes 52 performing emission of ther mal electrons are arranged at equal intervals inside the electron supply space 50. Together therewith, secondary electron emission plates 54 are arranged so as to surround said cathodes 52. when the cathodes 52 are heated in said constitution, a large number of electrons are emitted from said cathodes as thermal electrons. By keeping the secondary electron emission plates 54 at higher potential than the cathodes 52, said electrons are accelerated and collide with the secondary electron emission plates 54 and are amplified. In this way, the electron supply space 50 is made into a state full of electrons having the density corresponding to heating control of the cathodes 52 and potential control of the secondary emission plates 54. In the next place, the electrons inside the electron supply space 50 are accelerated by the strong electric field caused by the anode 20 and excite phosphor in colliding with prescribed part of the phosphor screen 10.

Title: Solid-state image sensor
Inventor: OOBA SHINYA
IPC: H04N5/335
Filed: 1979-07-02
Abstract: PURPOSE: To suppress the fixed pattern noise and to obtain high S/N, by inserting the switch element between the feedback circuit and the output terminal in the signal amplifier.  
     CONSTITUTION: The switch element 85 is inserted to the feedback circuit consisting of the preamplifier 83 and the feedback resistor 84, and the switch element 86 is inserted to the output terminal. When the switch elements 85, 86 are of MOS transistor type and the applied reset pulse ϕR to the gate 87 is at low level, since the switches 85, 86 are OFF, the signal charge is kept stored in the output line capacity. After that, when the horizontal switch is OFF and the pulse ϕR is at high level after the cause to the fixed pattern noise is avoided, both switches 85, 86 are ON, and the signal is normally read out without the effect of the fixed pattern noise. Since the switches 85, 86 are not directly inserted to the input terminal of the preamplifier, the increase in random noise is less and high S/N can be obtained in suppressing the fixed pattern noise.

Abstract: PURPOSE:To eliminate any influence of another load due to switching of a circuit, and also improve a fine operation property by driving left and right travel motors and a working machine actuator by switching a circuit. CONSTITUTION:Left and right travel motors 4 and 5 are driven with an independent circuit by discharge oil pressure of hydraulic pumps 2 and 3 at the time of travel operation only.

IPC: H02H3/05
Filed: 1988-04-06
Abstract: PURPOSE:To prevent erroneous function of a main detection relay, when a trip circuit is locked during automatic inspection of the main detection relay, by applying an automatic inspection command even onto a failsafe relay and locking the trip circuit. CONSTITUTION:A digital protective relay comprises a main detection relay 1 and a failsafe relay FSRy2 having independent hardware. The main detection relay 1 comprises a CPU3 for performing relay operation and automatic monitoring and a circuit 4 for outputting the results, and the main detection relay 1 closes the final stage output relay contact 8. When automatic inspection is carried out, a normally closed contact 7 for trip lock is opened through an OR gate 10 and an inspection command V is fed to the FSRy2. A CPU5 opens the normally open contact 7 by means of an output fed from an output circuit 6 based on the inspection command V then the CPU5 opens the final stage output relay 9 by means of a forcible operation output and closes the contact 7. Consequently, erroneous function is prevented even if the CPU3 in the main detection relay 1 runs away and automatic monitoring can be made reliably through a simple circuit.

IPC: H04N1/028
Filed: 1985-04-18
Abstract: PURPOSE:To improve optical response speed, by providing facing electrodes in a configuration, wherein the light receiving surface of each photoelectric conversion element is reduced in inverse proportion to the distance from each lighting window. CONSTITUTION:A light shielding layer 2, which is formed on a substrate 1, is etched, and a plurality of lighting windows 3 are formed. Then, a photoelectric conducting thin film is evaporated on the light shielding layer 2 and the lighting windows 3. Photoelectric conversion elements 5 are formed by etching and activated. A signal is taken out of one end of each photoelectric conversion element 5. The signals are combined at every unit number and imparted to a common electrode 12. The signal is also taken out of the other end of each photoelectric conversion element 5 and imparted to an individual electrode 13. The light receiving surface of the photoelectric conversion element 5 becomes small in inverse proportion to the distance from the lighting window 3 in the secondary scanning direction. Both electrodes 12 and 13 are formed so as to face to each other. Thus the optical response speed in a low lighting region is improved and becomes approximately equal to the optical response speed in a high illuminance region. The high speed in the close contact type image sensor can be achieved in this way.

Abstract: PURPOSE:To measure the rate of an electronic timepiece in a short period by providing a pulse forming circuit for rate measurement to be inputted with a signal from a frequency dividing circuit between the frequency dividing circuit and motor driver circuit. CONSTITUTION:An oscillation circuit 1 uses a quartz crystal, etc. as an oscillation source and outputs the signal to the frequency dividing circuit 2. The signal is frequency-divided down by every 1/2 in the circuit 2 and the signals are outputted from the necessary frequency dividing stages to the respective pulse forming circuits. The second hand operating pulse forming circuit 3 outputs the pulse P1 for driving a second hand operating motor 7 to the motor driver circuit 6 after waveform shaping. The minute hand operating pulse forming circuit 4 outputs the pulse P2 for driving a minute hand operating motor 8 to the circuit 6 after waveform shaping. The rate measuring pulse forming circuit 5 outputs the pulse for rate measurement having the pulse width which is shorter than the period of the pulse P2 and does not run the minute hand hand operating motor 8 to the motor driver circuit 6 after waveform shaping. The rate measurement in the period shorter than the period of the pulse P2 is thereby made possible when only the hour and minute hand display is used.

Inventor: MARUOKA HIROO
IPC: G01N21/90
Filed: 1986-04-11
Abstract: PURPOSE:To improve detection accuracy by detecting a buckled can by a light emitting device and a sensor head. CONSTITUTION:Cans 1 sent in order from a contents charging process are sent, one by one, in pockets 10a of a turret 10 by a front-stage auxiliary turret 11 and mounted on a turntable. Consequently, the cans 1 while rotating and revolving on their axes are covered through the clamping operation of a clamping roll and then conveyed to an inspection position A. When can 1 reaches the position A, light incident on the sensor head 14 is cut off by the can 1. Photodetecting elements on both side parts of the head 14 enter a 'light' state and the number of photodetecting elements in a 'dark' state at the intermediate part of the head 14 when a specific number of elements at the intermediate part enter the 'dark' state are counted; and the counted value is compared with a set value to detect bucking. If a buckled can is detected, an operation signal is sent to a solenoid valve 32 when the buckled can reaches a discharge position B, and air is injected from a discharge air pipe 33, thereby removing the buckled can.
