Title: Magnetic sensor
Inventor: MOTOKAWA MASARU
IPC: H01L43/02
Filed: 1986-07-29
Abstract: PURPOSE:To enable a magnetic field and an electrode to be formed of the same material while preventing terminals from shortcircuiting by a method wherein grazed parts are provided between terminals not to expose an alumina base rack for isolating terminals from one another. CONSTITUTION:Terminals 13-1-13-3 provided on corner parts of an alumina base rack 11 are isolated by respective glazed parts 12. Thus, when a magnetic field detector simultaneously filmed with the same material and a sensor main body 4 comprising electrode are etched, shortcircuit resistors R1-2, R1-3 and R2-3 between terminals have almost infinite resistance value at the end of etching process. Through these procedures, the terminals 13-1-13-3 are isolated from one another by the grazed parts 12 formed on the alumina base rack 11 so that the magnetic detector and the electrode may be composed of the same material to be etched simultaneously as well as the interterminal resistance may well exceed the resistance of magnetic field detector.

Title: Temperature alarm device
Inventor: SATO SHIGEO
IPC: F25D23/00
Filed: 1988-07-19
Abstract: PURPOSE:To obtain a temperature alarming device, alarming an abnormality after a given period of time when the abnormality in a temperature in a refrigerator is detected by a method wherein a high-temperature alarming lamp and a low-temperature alarming lamp, lighted by an alarming signal, are connected to a high and low temperature alarm generating circuit while an alarm buzzer circuit, operated by either of alarming signals is outputted, is provided. CONSTITUTION:When a temperature in a refrigerator is normal, a contact S is opened whereby a buzzer 12 is not sounded and an alarm is not outputted. When the temperature control of the refrigerator becomes abnormal and the temperature of the same has become high, the resistance value of a thermistor 1 becomes small and the output voltage of an amplifier 2 becomes low due to the reduction of a positive input voltage. In this case, the negative input voltage of a high temperature detecting circuit 4 becomes lower than the positive input voltage V2 and the output voltage of the circuit 4 becomes 'H'. Accordingly, a timer 6 is started and when the operation of the timer continues for a time T2, the output is changed from 'L' into 'H' and a high-temperature alarming signal is generated. Then, a transistor T2 is put ON, a luminous diode 8 emits light to effect high-temperature alarming indication, 'H' output is outputted from an OR circuit 9, the transistor 10 is put ON through a resistor R15 and a relay 11 is excited to close the contact S whereby the buzzer is sounded for alarming. According to this method, an abnormal condition may be judged surely.

Title: Hydraulic control device of variable valve timing mechanism
Inventor: MORIYA YOSHITO
IPC: F01L1/34
Filed: 1992-07-06
Abstract: PURPOSE:To secure the rapid operational responsiveness of a variable valve timing mechanism (VVT) and to stabilize the positional control when a ring gear is held at the intermediate position. CONSTITUTION:In a VVT where the valve timing is set variable by driving a ring gear 12 by the hydraulic power, the duty control of a control valve 28 to control the hydraulic pressure to the ring gear is executed based on the duty frequency which is synchronized with the phase inverted relative to the period of the torque fluctuation of a cam shaft 2 to be generated when an air intake valve is opened/closed. Thus, the hydraulic power which is periodically applied to the ring gear is exerted so as to cancel the thrust force to be periodically added to the ring gear caused by the torque fluctuation of the cam shaft, leading to reduction of the resultant force fluctuation. The ring gear is not moved by the thrust force accordingly.

Title: Magnetic sensor circuit for positioning apparatus
Inventor: SHIMIZU SHINKICHI
IPC: G01D5/18
Filed: 1987-07-16
Abstract: PURPOSE:To reduce a sensitivity deviation using a handy construction, by inputting a reference voltage into one feedback amplifier while a magnetic sensor and a sensing resistance are connected to the other input terminal. CONSTITUTION:A reference voltage Vr is inputted into one input terminal of a feedback amplifier 10 to match polarity while a magnetic sensor 1 is inserted and connected between the other input terminal and an output terminal while a sensing resistance 11 is connected between the other input terminal and the ground. With such an arrangement, as an input impedance of the feedback amplifier 10 is high, a constant current circuit is built and said reference voltage Vr develops across ends of the sensing resistance 11. This allows the flowing of a fixed current because a feeding back is imposed, regardless of any change in current flowing through magnetoresistance elements 1-1-1-4 and the sensing resistance 11. As the fixed current flows, a voltage generated of a magnetic sensor 1 goes up with a rise of the temperature to compensate for the sensitivity of the magnetoresistance elements 1-1 and 1-4.

IPC: H01J29/48
Filed: 1989-07-13
Abstract: PURPOSE:To prevent the occurrence of a residual image, etc., by reading a signal electric charge on a photoconductive film with an electron gun on a tube axis, and discharging a surplus stored signal electric charge on the photoconductive film by the beam of another electron gun provided outside the tube axis during the flyback- time of the electron beam of the electron gun on the tube axis. CONSTITUTION:The stored signal electric charge of a photoconductive film 15 ia read out by an electron beam 4 emitted from an electron gun on a tube axis during a scanning period. Moreover the reading-out of the stored signal electric charge of the photoconductive film 15 by an electron beam 7 from a cathode 5 outside the tube axis is privented during the scanning period by setting the electric potential of the cathode 5 outside the tube axis higher than the back surface electric potential of the photoconductive film 15 produced by the incidence of high brightness light. During the flyback-time, emission from the electron gun on the tube axis is stopped, the electric potential of the cathode 5 outside the tube axis is lowered, and the surplus stored signal electric charge, which can not be eliminated by the beam electric current quantity of the electron gun on the tube axis, of the photoconductive film 15 is eliminated by the electron beam 7 from the cathode 5 outside the tube axis. Thus the occurrence of a comet-tail and a residual image, etc., can be prevented.
