Title: Current detecting circuit
Inventor: SUGIE YOSHIZO
IPC: H01L29/78
Filed: 1989-07-19
Abstract: PURPOSE:To eliminate power loss, decrease temperature dependency, and realize high accuracy, by detecting current flowing through an output power element based on detection of potential variation of an N<+> substrate or an N<+> buried diffusion layer providing a current path. CONSTITUTION:Power MOS's (M1, M2, M3, M4) for output use are constituted in H-type, and drive a motor M. Diodes D1, D2, D3, D4 are built-in diodes of the power MOS's (M1, M2, M3, M4), respectively. In order to detect load current of the H bridge circuit, N<+> substrate potentials VS1, VS3 of the upper side power MOS's (M1, M3) are compared through a voltage comparing circuit 100. For example, a case where M1, M4 are ON, and M2, M3 are OFF is considered. Since drain current ID1 flows through M1, M4, potential VS1 of M1 is lower than the source voltage VDD by an amount of ID1.RNSUB. On the contrary, since drain current does not flow through M2, M3, potential VS3 of M3 remains at VDD and potential difference between then is proportional to ID1. Consequently load current of the power MOS can be detected under a state where power loss does not present and temperature dependency scarcely exists.

Title: System for searching vicinal map in map research device
Inventor: NAKAZAWA KOJI
IPC: G06F17/30
Filed: 1984-09-04
Abstract: PURPOSE:To minimize the delay required for searching vicinal map by anticipating the positioning of operation for reading the vicinal map in the searching of vicinal map. CONSTITUTION:A discriminating means 6 of the position to start the searching of map recognizes displacement performed by direction indicating means 9, i.e. the displacement of pointer through a controller 8. The discriminating 6 stores the recognized displacement as a point defined in the rectangular x- and y- coordinates to travel the pointer to the coordinates corresponding to a map display means 12. The discriminating 6 discriminates whether the result added with the displacement is out of the area of map or not. When the result is out of the area, the vicinal map to the direction of the controller 8 is read from a map input means 11 through a controller 10 to be displayed on the map display means 12.

Title: Information recording and reproducing apparatus
Inventor: UNNO HIROJI
IPC: G11B7/085
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To provide an information recording and reproducing device capable of performing an exact access at a high speed, even with respect to an optical disk having wobbling of the surface. SOLUTION: An object lens position control part 15 controls a tracking drive part 17, based on a light-receiving spot displacement detecting signal detected by a light-receiving spot displacement detecting part 11 in an access mode. Here, when accessing to an optical disk 1 having wobbling, undulation resulting from the wobbling arises in the light-receiving spot detecting signal. This undulation appears also in a focal control signal outputted from a focal control part 21 in similarity forms. Therefore, the wobbling component is offset from the light-receiving spot detecting signal by assigning weight with respect to a focal control signal by a weight assigning part 22, and subtracting this weighted focal control signal from the light-receiving spot detecting signal.  Thus, this arrangement prevents on object lens 4 from being undesirably controlled to move at accessing, and enables an exact and quick access.

Title: Dummy resistance circuit for constant current power source
Inventor: OUCHI MASAHIRO
IPC: G05F1/56
Filed: 1987-07-24
Abstract: PURPOSE:To improve the efficiency of a power source, by suppressing power consumption due to a dummy resistor at a minimum level by varying the value of the dummy resistor corresponding to a load. CONSTITUTION:The secondary side of a transformer T is connected to the load Z via the dummy resistor RD, and the emitter and the collector of a PNP transistor TR1 are connected in a forward direction in parallel with the dummy resistor RD. When a load voltage Vo is increased, potential is generated between the (+) and (-) input terminals of an operational amplifier Ic1, and the base current of a transistor TR2 is increased, thereby, the collector current i3 of the transistor TR2 is increased. In the transistor TR1, the current i2 moving from the emitter to the collector is increased by the increase of the base current i3, and an input voltage Vi is transmitted to the load Z without being affected by the dummy resistor RD, then it goes to i=Vo. In such a way, since voltage drop due to the dummy resistor RD is eliminated, the efficiency of the power source can be improved.

Abstract: PURPOSE:To enable to absorb the thermal energy radiated from heating elements employing an extremely simple constitution and to discharge the same to outside by a method wherein two opposed sheets of plates, which were processed in such a manner that the radiation wavelength and the absorption wavelength are varied to each other, are inserted between heating elements. CONSTITUTION:Between heating elements 11 and 12, two sheets of plane plates 1 and 2, having different discharge and absorption characteristics, are placed facing each other leaving a space between them. As regards the thermal energy discharged from the heating elements 11 and 12, the first range of thermal energy wavelength of the thermal energy, which was incidented upon the surfaces 3 and 4 of the plane plates 1 and 2, is absorbed by the plane plates 1 and 2 at the absorption factor for respective wavelength. The absorbed thermal energy which was absorbed by the plane plates is discharged in accordance with the emissivity within the second range of the thermal energy wavelength and reflected to the direction of the plane plate 1 without being absorbed by the opposing surface 6 of the plane plate 2. The thermal energy reflecting in the direction of the plane plate 1 from the opposed surface 6 of the plane plate 2 is reflected in the diection of the plane plate 2 again without being absorbed into the plane plate 1, because its thermal energy wavelength is unchanged. By repeating the above movements, the thermal energy is discharged and flows from the intervals 21 and 22 of the plane plates 1 and 2 in the direction as shown by the arrow j and k.
