Title: Image sensor and its manufacturing method
Inventor: MURAMATSU YOSHITOKU
IPC: H04N5/374
Filed: 1999-12-03
Abstract: PROBLEM TO BE SOLVED: To obtain an image sensor in which a column-oriented wiring region is lessened in area so as to more enhance a photodetecting part in area and photoelectrically converted signals are prevented from being damaged by coupling noises in a read-out operation. SOLUTION: Two column-oriented selection lines, a column selection line 3 and a signal reset line 2, are arranged so as to overlap with each other through an insulating film. By this setup, a photodetecting part can be enhanced in area. The column selecting line 3 is formed of wiring member which is higher in resistance than that of the signal reset line 2, or the column selection line 3 is set higher in resistance than the signal reset line 2 by regulating a wiring in cross sectional area. By this setup, coupling noises hardly affect the signal reset line 2.

Title: Operation method for vehicle-heating system and heating system for vehicle
Inventor: PEETAA KOTSUKU
IPC: B60H1/03
Filed: 1989-12-28
Abstract: PURPOSE: To enhance engine preheating performance and indoor heating performance by circulating a coolant through an entire coolant circulation path up to a first predetermined temperature, circulating the coolant between the intake and outlet of a heating device at temperatures equal to or higher than the first temperature and up to a second temperature, and then gradually returning the coolant to circulation through all circulation paths. CONSTITUTION: When a fuel-operated heating device 7 is turned on, a bypass line 10 is closed by a control valve 11. A coolant is circulated within an engine 2, the heating device 7, and a vehicle heater 4 as long as the temperature detected by a temperature sensor is not higher than a first temperature which is about 30 deg.C at a maximum. Until the coolant temperature exceeding the first temperature has reached a second temperature of about 70 to 80 deg.C, the control valve 11 is opened to allow a large amount of coolant to flow through the bypass line 10 to reduce the amount of coolant passing through the heating device 7 so as to increase heating rate. After reaching the second temperature, the control valve 11 is gradually closed to return the coolant to circulation through all circulation paths.  Engine preheating performance and heating performance can be enhanced by this constitution.

Title: Optical disk device, optical disk discrimination method and information processor
Inventor: ITO NOBUHIKO
IPC: G11B7/085
Filed: 1999-12-03
Abstract: PROBLEM TO BE SOLVED: To simply and rapidly discriminate the number of layers of an optical disk without using an S-shaped curve by focus drawing operation. SOLUTION: An objective lens performs the focus drawing operation from the direction where a recording layer of a large layer number can exist (step S4). Disk peculiar information, e.g. sector information of an ID of an optical sector is reproduce on the focused recording layer (S5). The number of layers of the loaded optical disk is discriminated by the layer number information (S6, S7, S8), then the number of layer structure is discriminated only with the initially focused recording layer, so that the discrimination is finished only with the focus drawing operation for one recording layer to shorter the time required for the discrimination processing of the number of layer, and the S- shaped curve accompanying the focus drawing operation is not used to perform the discrimination processing less in the effect of a noise.

Title: Semiconductor integrated circuit
Inventor: SHIMOMURA KENICHI
IPC: H01L29/78
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To enable both high-speed operation and low-power consumption by changing the potential of the potential controlling terminal of a substrate in the pulse state into a direction, in which the threshold voltage becomes low corresponding to the rising and falling timings of an input signal into the gate of a MOS transistor. SOLUTION: A bias control circuit 103 decreases a back-node potential BP of a P-channel MOS transistor 101 during the period, from the time when an input signal IN starts to change into Low to the time when an output signal OUT is changed into High. Furthermore, a bias control circuit 104 increases a back-node potential BN of an N-channel MOS transistor 102 during the period, from the time when the input signal IN starts to change to High to the time when the output signal OUT is changed to Low. Thus, the drive capability of the MOS transistor is improved, and the circuit operation becomes quick. Therefore, the period for increasing the drive capability is suppressed to a minimum, and the increase in power consumption can be suppressed to a minimum.
