A substrate inspection apparatus includes a first waveform measurer which acquires a first amplitude waveform that is the amplitude waveform of an AC voltage obtained from a semiconductor of a semiconductor substrate which is being inspected when an external AC power source is connected to the semiconductor and an AC voltage from the AC power source is applied to the semiconductor, the semiconductor substrate also having an interconnection that is supposed to be connected to the semiconductor; a second waveform measurer which is connectable to the interconnection of the semiconductor substrate and acquires a second amplitude waveform that is the amplitude waveform of a voltage in the interconnection when the AC voltage is applied to the semiconductor; and an evaluator which calculates the phase difference between the first amplitude waveform and the second amplitude waveform and extracts information on a defect of the semiconductor substrate on the basis of the thus-calculated phase difference.

Disclosed is an adaptive control apparatus having an error calculation unit for calculating the difference between a reference signal and a feedback signal, and an adaptive controller for applying adaptive control so as to diminish the difference and causing the result of adaptive control to be reflected in the reference signal. The adaptive control apparatus has a delay unit for delaying at least one of the reference signal and feedback signal by a set delay time in such a manner that the reference signal and feedback signal will be input simultaneously to the arithmetic unit; a frequency-component detecting unit for detecting a frequency component of the reference signal; a delay-time acquisition unit for acquiring delay time conforming to the frequency component; and a delay-time setting unit for setting the acquired delay time in the delay unit.

In a vehicle air conditioner, a variable displacement compressor has a control valve for continuously changing a discharge capacity of the compressor, and a control unit calculates an electrical value DT to be applied to the control valve based on the following formula of DT=DT(n−1)+Kp[(En−En−1)+C/(Ti×En)]. In this formula, En=Te−Teo, Kp=Kp′/(Ph×Ph′), Ti=Ti′/(Ph×Ph″), C is a sampling cycle, n is a positive number, Kp′, Ti′, Ph′ and Ph″ are constants, Ph is a refrigerant pressure at a high pressure side, Te is a detected air temperature at an air outlet of the evaporator, and Teo is a target evaporator air temperature that is calculated based on an outside air temperature Tam. Accordingly, the compressor can be stably controlled in a wide thermal load range.

The present invention provides a single information recording and reproducing apparatus that is used to record data to multiple disks that are to be recorded on using different wavelengths. More specifically, the present invention provides an apparatus that accurately discriminates disk types while preventing disk damage and accidental recording of data during the disk type discrimination operation. The disk type is determined using the intensity of light reflected from the disk. Information is encoded using an encoder corresponding to the disk type. The resulting signal is used to drive a laser corresponding to the disk type, and information is recorded.

A rubber-erasable aqueous ink for a writing material composition contains water, a water-soluble polar solvent, and a particulate adhesive colored resin. The particulate adhesive colored resin contains a pigment and an adhesive resin which is adhesive on at least a part of a surface thereof. The particulate adhesive colored resin has a particle diameter distribution such that the amount of particles having a particle diameter of from 2 &mgr;m to 20 &mgr;m is not less than 70% by weight of all the particles.

A second connector (15) on an engine control unit (10)side is directly fixed to the engine control unit (10) and the engine control unit (10) is fixed in the interior of the equipment box (4) in such manner that it finely moves therein. A first connector (25) on an instrument panel (20) side is gradually moved up in a vertical direction, while being faced to the second connector (15) on the engine control unit (10) side for connection of the fist connector (25) and the second connector (15) Lever-type connectors are used as the first and second connectors (25) and (15) which have a function to reduce a load resulting at the time of connection of the connectors.

A water-resistant electrical connector has a flow-down space S, through which water passes, formed between the outside surface of female terminal housings 30 and the inside of a male hood 12. Water which penetrates inside the male hood 12 from the end thereof passes through a flow-down space S to exit apertures 20, 37. Neighboring terminals are separated by hollow partition walls 11, 31. Partition walls 18 may project from the male connector and pass between adjacent female terminal housings to improve electrical isolation.
摘要:
A lever type connector includes a lever, and a first connector and a second connector to be connected to each other. Two pins formed on the first connector are inserted through the through-opening formed on each of two separate components of the lever. Then, the two components are connected to each other by, for example, an automatic ultrasonic welding device, so that it is unnecessary to expand one of the components of the lever in installing the components on the first connector in contrast to the conventional method. The components of the lever can be installed on the first connector with no deformation or breakage occurring in the components because no great force is applied.

In a CD-ROM disk reproducing device, for a data read instruction which specifies an address issued frequently from a host computer, irrespective of whether the device has a Lock Cache function, the time required from receipt of a data read instruction up to the actual data transfer is reduced. The data read instruction which specifies an address issued frequently from the host computer is discriminated by a microcomputer constituting a control section in the device and the read data from the address is locked in a storage section (buffer RAM) so as not to be erased. When a data read instruction specifying the same address is received afterward, data is read out directly from the storage section and transferred to the host computer.

Protecting walls project in a certain length from an end of an opening portion of a connector to be connected with a connector. The protecting walls are opposed to a part of a lever projecting in a length of from each of sides of the lever beyond the end of the opening portion of the connector.
