Abstract: PURPOSE:To confirm the performance without operating the operation part of a device for inspection and to easily coverall operation for inspection by registering response data in advance corresponding to the operation sequence. CONSTITUTION:The operation sequence for inspection and the normal response data corresponding to each operation are recorded in a recorder 13 for operation - response data.

Filed: 1980-10-30
Abstract: PURPOSE:To judge the stability of a semiconductor device from the quantity of variation of a flat band voltage by a method wherein the energy of carrier is enhanced by light, and the device is treated for the prescribed time in the room temperature applying a bias voltage. CONSTITUTION:The capacitance C-voltage V characteristic curve a of an MOS diode consisting of an Si substrate 5, an SiO2 film 6, electrodes 7 is obtained. Then a bias voltage is applied irradiating the MOS diode with a W lamp 9. Whe doner type traps exist in the insulating film 6, electrons are discharged from the traps carying positive electric charge by the application of a negative bias voltage, and C-V characteristic transfers in the negative direction as shown with the c curve.  When a positive bias voltage is applied, the curve thereof transfers in the positive  direction as shown with the b curve. Therefore the flat band voltage are obtained  from respective C-V characteristics, and the unstable component owing to the traps can be measured from quantity of variation. At the neighborhood of the room temperature, almost no movable ion of Na<+>, etc. in the insulating film transfers, the  unstable component owing to ions thereof can be separated, and only the unstable  component owing to the traps can be measured.

Title: Image recorder
Inventor: SATO ISAMU
IPC: G03G15/00
Filed: 1993-06-23
Abstract: PURPOSE:To avoid such accident as firing or smoking by bringing a DC lower supply into a second mode, i.e., waiting state, when an image recorder detects an abnormality thereby blocking spread of abnormal state. CONSTITUTION:The mode (output capacity) of a DC power supply 47 is changed according to the operating state or waiting state of an image recorder. A first mode exhibiting maximum output capacity is brought about for the recording operation state and an automatic transition is made to a second mode ensuring the minimum necessary output capacity for the waiting state. When a recording paper is jammed or an abnormality is detected in a control load under the operating state of image recorder, the mode of the DC power supply 47 can switched to second mode in order to block spread of the abnormal state. Even if short circuit of cable, abnormality in control load, etc., occurs under waiting state of image recorder, such accident as firing or smoking can be avoided because the output capacity of DC power supply is low.

Abstract: PURPOSE:To enable switching at high voltage, by preventing the destruction of a switching MOSFET constituting bootstrap circuit, through the provision of depletion type MOSFET of stack gate construction between a load means and the switching MOSFET. CONSTITUTION:A depletion MOSEFTQ14 of stacked gate construction is provided, in which about 30 volts are taken as a power supply voltage VPP, a prescribed high voltage V'P(VPP-2X threshold voltage of MOSFETsQ1, Q2) is applied to the 1st gate G1 of the drain connected to the FETQ13 between the load MOSFETQ13 and the switching MOSFETQ15, and a prescribed low voltage Vcc (about 5volts) is applied to the 2nd gate G2 of the source side connected to the FETQ15. While the drain voltage of the FETQ15 is clamped by about 8volts by the gate G2 applied with the voltage Vcc, a relative potential difference between the gate G1 applied with a high voltage and the bootstrap high voltage can be made small, allowing to prevent the destruction of the FETsQ13, Q14.

Filed: 1983-08-20
Abstract: PURPOSE:To accurately detect the exchange time of a filter by simply judging the contamination state of the filter by the discoloration of an indicator for detecting the contamination degree of air, by attaching said indicator to the lee side of the filter provided to a household air purifier. CONSTITUTION:A filter block 9 formed by superposing a dust removing filter 17 and a deodorizing filter 18 is attached to the air sucking port of a household air purifier as an air purifying filter. The dust removing filter 17 is formed of filter paper 21 pleated in a zigzag pattern and the deodorizing filter 18 is prepared by filling the space formed by a filter frame 23, a rear plate 24 and a press plate 25 with a deodorant 26. Indicators 19, 20 for detecting the contamination degree of air, each of which is formed by molding an electrostatic fiber filter or a solid adsorbent such as zeolite into a plate shape, are attached to the lee side part of each filter. When the capacities of the filters 17, 18 are lowered and air passing the filter becomes dirty, the indicators are discolored and, therefore, by comparing with a color sample, the exchange time of tha filter is determined.

Title: Video integration averaging device
Inventor: ASADA KAZUYOSHI
IPC: G06T5/00
Filed: 1988-06-22
Abstract: PURPOSE:To make unnecessary an addition at 16 bits by setting the coefficients of two coefficient multipliers so that the coefficients of the two coefficient multipliers may be positive, their sum may be '1' whenever a video signal is inputted, and the respective inputted video signals may be multiplied by a weight determined beforehand when all integrations are completed. CONSTITUTION:When an input picture and an integration value until such a time fetched by a picture memory 106 are both at 8 bits, by multiplying the positive coefficients, whose sum is at '1', and by adding the obtained value to the former values by an adder 105, an addition result does not exceed 8 bits. There, as the coefficient to satisfy the said condition, the i-th coefficient is set at 1/i with respect to the input video signal, and the coefficient is set at 1-1/i=(i-1)/i with respect to the integration value up to an (i-1)-th time, the value of 1/M times is obtained with respect to the addition for totally M times, and the (i) is made unrelated. That is, the all input video signals are multipled and added by the same weight 1/M by means of coefficient multipliers 103 and 104. Thus, the simple mean value of the whole signals can be obtained as the integration value for the memory consisting of one picture element at 8 bits.

Title: On-vehicle voice recognition device
Inventor: KURIKI SHOJI
IPC: G10L21/02
Filed: 1990-06-11
Abstract: PURPOSE:To improve the recognition rate of unspecified speaker recognition by approximating characteristics of an input voice in a vehicle to characteristics of a voice data base used to generate an unspecified speaker dictionary. CONSTITUTION:The power voltage of a voice signal is converted into a digital value, channel by channel. The power of each channel has frequency characteristics of the input in the vehicle, so this power is multiplied by reverse characteristics calculated for the sound recording characteristics in a studio in advance to correct frequency characteristics. A voice section detector 11 detects a voice section from the corrected channel power data and a feature extraction part 12 detects the feature quantity of the voice to generate a voice input pattern 13. This pattern is compared with dictionary patterns in the unspecified speaker dictionary 15 and a recognition part 14 employs the most similar word as a correct answer, so that an output part 16 outputs the recognition output. Consequently, the recognition rate is improved.
