Title: Remote sensing circuit
Inventor: NOJI HIDEO
IPC: H02J1/00
Filed: 1989-10-31
Abstract: PURPOSE:To prevent the overload of a power circuit by controlling the output voltage of the power circuit through operating a change-over switch by the output values of two detecting elements for detecting the output voltage of the power circuit and the input voltage of a load. CONSTITUTION:At the time of starting an apparatus, the common terminal C of change-over switches SW3, 4 are connected with a terminal A and the output voltage of a power circuit 1 is detected by a first voltage detector 5. The output voltage of the power circuit 1 is compared with a reference voltage 6, error-amplified 7, and stabilized via control circuit 8. Then, the input voltage of a load 2 is detected by a second voltage detector 9 and compared with a reference voltage 10. When there is an error exceeding a predetermined value, coils 3a, 4a are energized so that SW3, 4 are turned to a terminal B and the output voltage of the power circuit 1 is controlled like when an apparatus is started. Also, when the input voltage of the load drops by any abnormality neither the coils 3a, 4a operate nor the voltage of the power circuit 1 rises. Thus, the power circuit 1 is prevented from overvoltage or oscillation.

Title: Manufacture of semiconductor device
Inventor: NISHIZAWA MASATO
IPC: H01L21/02
Filed: 1985-12-17
Abstract: PURPOSE:To be useful for facilitating the verification of the directional property of a chip when bonding the electrode portion of the divided chip onto a substrate in a face down condition by repeatedly providing marks indicating the directional property more than the number of chips at an interval less than the size of the chips on the counter-electrode surface of a semiconductor plate before dicing. CONSTITUTION:On the surface opposite the surface on which the electrode of a semiconductor plate 1 is to be provided, mountain-shaped marks 2 are formed so that the top of the mountain is directed vertically with respect to a cut portion 3 which is to be the reference of the direction of the semiconductor plate. A pattern of such marks is formed on the plate as projections or recesses by etching after applying a resist on the semiconductor plate 1 and forming a resist pattern using a photo mask. Etching can be performed fast for recessed marks, while projective marks have an advantage that they are easy to see. Since the marks 2 on the chip surface indicate a fixed direction with respect to the electrode pattern provided on the opposite surface, the direction is visually verified when performing the face down bonding to enable the work to quickly proceed.

Title: Protecting circuit
Inventor: KOUNO TOSHIYUKI
IPC: G05F1/10
Filed: 1999-10-05
Abstract: PROBLEM TO BE SOLVED: To actualize small circuit loss and simple constitution, to effectively prevent a rush current, and to enable protection against an overvoltage. SOLUTION: When a voltage is applied from a voltage supply source 1 through connectors 2 and 2', a gate voltage is applied to turn on a MOSFET3 and a drain current begins to flow. Through a resistance 4. inserted between the source and drain of the MOSFET3 in series, a capacitor 16 of a switching power source 15 is charged. After the gate voltage gently rises by resistances 8 and 9 and a capacitor 10, a MOSFET5 turns on. Thus, the MOSFET5 turns on and then the series circuit of the source and drain of the MOSFET3 and the resistance 4 is short-circuited. When an overvoltage is generated, an input overvoltage detecting circuit 14 detects the overvoltage and a transistor 13 turns on to turn off both the MOSFETs3 and 5 through diodes 11 and 12.

Title: Headlight device for vehicle
Inventor: MORI TAKAKAZU
IPC: F21S8/10
Filed: 1993-11-15
Abstract: PURPOSE:To control the light distribution in front of a vehicle so as to recognize an obstacle by a driver of the own vehicle in the running condition. CONSTITUTION:A scope setting process is made to an image taken by a TV camera (200), and after an obstacle detecting process is carried out, the existence of an obstacle is decided (202 and 204). When there is no obstacle, a normal light distribution control to improve the visibility and to prevent a glare is carried out (214). On the other hand, when there is an obstacle, the upper end of the obstacle is measured (206). Then, the position of the cut line by the present shade position is stored (208), and by deciding whether the upper end of the obstacle is near the cut line or not, it is decided whether the normal light distribution control will do or not (210). When the answer is no, a light distribution control to light on the obstacle is carried out (212). By placing the priority to the light distribution to light on the obstacle in such a way, the driver can recognize an obstacle such as a walker securely.
