Title: Control device for vehicle
Inventor: UEDA YOSHIAKI
IPC: F02D45/00
Filed: 1995-06-08
Abstract: PURPOSE: To provide a control device for vehicle in which the disconnection of an earthing conductor can be precisely identified from the disconnection of a signal line or a normal state. CONSTITUTION: The signal lines of an oil temperature sensor 16, a water temperature sensor 15 and an engine rotating speed sensor 19 are connected to input circuits 21A, 21B, 22A, respectively, by commonly using an earth terminal 20A. A microcomputer 27 detects the detection signal of the oil temperature sensor 16 and intermittently repeats to identify whether it is within a predetermined failure detecting range or not. When the frequency of judgment of the failure detecting range reaches a prescribed limit value, an engine 11 and an automatic transmission 12 are made to execute a fail-safe control. Since the earth terminal 20A is commonly used, the number of connector pins or the number of wirings is reduced, and no special circuit for detecting the disconnection of an earthing conductor is needed.

Title: Water heater
Inventor: OKAWA SEIICHI
IPC: F24H1/10
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To prevent an excessive rise in the temperature of hot water by providing a water quantity sensor detecting a flow rate of water passing through a heat exchanger and a hot supply water temperature sensor measuring the temperature of hot supply water and by determining whether a controller controlling heating of the heat exchanger is normal/abnormal on the basis of a set signal of the temperature of the hot supply water and a measuring signal of the hot supply water temperature sensor. SOLUTION: At the time when a flow of water in the minimum working water quantity or above is detected by a water quantity sensor 1, a signal of start of heating is sent to a controller 2, the amount of heating of a burner 4 is controlled by a burner controller 3 so that a signal of a hot supply water temperature sensor 5 may coincide with temperature setting of a temperature setting unit 6, and a heat exchanger 7 is heated. In other words, the quantity of heat is controlled variably by controlling a main solenoid valve 3a and a fuel control valve 3b in the burner controller 3. The controller 2 has a hot supply water temperature determining part and a time determining part and determines the amount of heating, that is, whether a normal temperature control is conducted or not.  When the amount of heating becomes a prescribed one or above, a heating stop signal is transmitted from the controller 2 to the burner controller 3 to stop combustion of the burner 4, so as to prevent an excessive rise in the temperature.

Filed: 1980-11-26
Abstract: PURPOSE:To prevent the intermission of reception sound due to weak or strong reception desired waves, by providing a switch which switches an incoming tone generator and a low frequency amplifier to normal and nonoperation, to an FM receiver. CONSTITUTION:After a power switch 16 turns on, a response switch 17 is at off- position when no desired reception wave is present, and an FM receiver 3, an HPF6 passing through noise except the signal frequency band, a noise amplifier 7, a rectifying circuit 8 and an incoming tone generator B are operative. Thus, no noise passes through a low frequency amplifier 4 and no output is obtained from a speaker 5. When a desired wave is received, since noise is suppressed, the output of the circuit 8 is absent, a switching circuit 10 drives a low frequency oscillator 11 and an incoming tone is generated from a speaker 12. A switch 17 is connected to the one-side and the operation of the device B is stopped, the amplifier 4 and a transmitter 13 are operative and simultaneous transmission/reception can be made.

Title: Negative electrode structure of electron gun for cathode-ray tube
Inventor: KIM CHANG-SEOB
IPC: H01J3/02
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To reduce the electrostatic capacity of a gate electrode layer, and to prevent the distortion of the driving signal by dividing a second gate electrode layer, and arranging the second gate electrode layers at positions except for parts on a cathode electrode layer and a cathode lead unit. SOLUTION: Both electrical potentials are applied to a first and a second gate electrode layers 56, 57 so as to control the quantity of electron to be emitted from a metal chip 53. The second gate electrode layer 57 is divided, and since the second electrode layers 57 are not positioned on a cathode electrode layer 52 and a cathode lead unit, electrostatic capacity of the gate electrode layer can be reduced. Especially, since a lower surface of an insulating layer 54 is not formed with a cathode electrode layer 52, storage of charge is prevented so as to reduce the electrostatic capacity. With this structure, distortion in the drive signal for controlling the electron beam to be generated from the metal chip can be prevented.

Title: Printer
Inventor: MAKINO KOSHIN
IPC: B41J11/42
Filed: 1989-06-29
Abstract: PURPOSE:To make a printer compact and light-weight at low cost by moving back and forth a mechanical part for cutting or stamping paper using a motor for rotation of a paper feed roller. CONSTITUTION:After ending printing, a stepping motor 23 rotates in 'B' direction and a gear pulley 22 rotates in 'B' direction, if a cutting signal is output. However, the rotation in said direction is not transmitted to a platen shaft 13 by a one-way clutch 26 and therefore, paper 61 is not fed. In the meantime, if the gear pulley 22 is rotated in 'B' direction, a groove cam 31 rotates in 'A' direction, and an engagement pin 44 located in the first cam groove 34 reaches a guide part 37, guided by the first cam groove 34 following the rotation of the groove cam 31 in 'A' direction. In this case, since the edge of the guide part 37 is a step 37A the pin 44 does not advance to the first cam groove 34 but is guided to the second cam groove 35. Then the engagement piece 46 sways vertically with a shaft 42 working as a fulcrum depending upon the eccentric value of the second cam groove 35. Consequently, a movable blade 57 sways and a cutter arm 43 cuts paper 61.

Title: Controlling system for current of self-excited voltage-type ac-dc converter
Inventor: OSHIMA MASAAKI
IPC: H02M7/48
Filed: 1993-06-14
Abstract: PURPOSE:To use an arbitrary function as the target function of an AC current and to use an arbitrary value as the targer follow-up error with of the AC current by a method wherein, when the compared result of the AC current of a linkage point with a reference value is deviated from a prescribed set range, the switching mode of an AC-DC converter is made to follow up the reference value. CONSTITUTION:The AC current i(t) of a linkage point in a main circuit and an arbitrary target function j(t) are input respectively to a subtracter 2. The subtracter 2 detects the difference between the AC current i(t) and the target function j(t), and the difference (error signal) is input to an operation circuit 4. The operation circuit 4 outputs a gate signal which increases/decreases the AC current i(t) when the error signal is deviated from the lower limit -j(t) and/or the upper limit and/or the lower limit of a target follow-up signal j(e). Thereby, an arbitrary function can be used as the target function j(t) of the AC current i(t), and an arbitrary value can be used as the target follow-up error width of the AC current i(t).

Abstract: PURPOSE:To obtain copied reproduced images according to desirable selected density by providing a control means for keeping potential difference between a developing sleeve and a toner recovering roll at a constant value by altering a recovering bias voltage. CONSTITUTION:The control means for keeping the potential difference DELTAV between the developing sleeve 4 and the toner recovering roll 9 at a constant value by altering the recovering bias voltage Vss as soon as the copied image density is adjusted by altering a developing bias voltage Vb is provided on the titled machine.

Then, in a state where the toner concentration is constant, developing is executed based on the potential difference between the developing sleeve on which altered developing bias voltage is impressed and an electrostatic latent image carrier whose electrified potential is constant. Thus, the reproduced image according to the desirable selected image density can be obtained even if the developing bias voltage is altered.
