IPC: H03F3/181
Filed: 1989-08-18
Abstract: PURPOSE:To reduce the man-hour and time in the case of conducting the test of an operational amplifier by providing a test circuit having a switch between an external input terminal and two (noninverting and inverting) input terminals of the operational amplifier itself and forming a voltage follower at the test. CONSTITUTION:An operational amplifier circuit 1 consists of an operational amplifier 2, MOS transistors (TRs) 3-6, an inverter 7, external input terminals 8, 9 and a test signal terminal 10. In the normal mode, a switching signal TEST is brought into an 'H' level. Thus, MOS TRs 4, 5 are turned on and MOS TRs 3, 6 are turned off, analog input signals AIN1, AIN2 are fed to the input terminal of the operational amplifier 2, the forming of the voltage follower is released and the normal operation is implemented. In the test mode, the switching signal TEST is brought into an 'L' level. Thus, the MOS TRs 4, 5 are turned off and MOS TRs 3, 6 are turned on, a test signal TN is fed to a noninverting input terminal of the operational amplifier 2, the voltage follower is formed, the test of the operational amplifier 2 is conducted and the result is extracted from an external output terminal 12.

Title: High voltage switch circuit
Inventor: HATA YOUGO
IPC: G01S7/52
Filed: 1983-11-14
Abstract: PURPOSE:To improve the isolation by connecting a pull-up resistor and a field transistor (TR) switching a high voltage signal to the cathode of a diode. CONSTITUTION:The pull-up resistor R1 applying a DC high voltage to the cathod and the field effect TR switching the high voltage signal are connected to the cathode of the diode D1 connected in the forward in a direction passing through the high voltage signal. Thus, since the switching of the diode D1 is executed in parallel by the switching of the field effect TR, the isolation is improved.

Title: Device for specifying system design specification
Inventor: GARY F DE PALMA
IPC: G06F17/50
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To provide a method by which a programmer who does not have the detailed knowledge of system design or high knowledge on logic expression regulating system specification can easily verify system design. SOLUTION: A system designer can precisely regulate system specification by using the finite number of templates. The finite number of templates supply few and comparatively facile means for understanding expression for considerably simplifying/clarifying the treatment of design specification and for making it reliable. The advantage of it is to eliminate the necessity of an experienced programmer for writing multiple and complicated logic expressions required for regulating system design specification used for a former certification tool and a simulation tool. Thus, a former design limit cant be solved to a certain degree.

Title: Device for shifting pin of resistance welding machine
Inventor: ITO HIDEAKI
IPC: B23K11/14
Filed: 1987-08-27
Abstract: PURPOSE:To prevent a guide pin from being embrittled and broken by circulating inert gas or air between the guide pin and electrodes. CONSTITUTION:At the time of performing welding, while the inert gas such as carbonic dioxide gas is allowed to flow in from a gas inflow port 20c, a link rod 14 in a toggle mechanism 6 is drawn near the driving source 13 side and the guide pin 5 is made in a projected state. Holes provided to a plate body and a small part are put on a projection 5a and in a state with these set up on an lower electrode 8, an upper electrode 8 is lowered to perform projection welding. At this time, since the plate body and the small part are positioned by the guide pin 5, the welding is performed without the dislocation and the small part is pressed against the side of the pin 5 by electromagnetic repulsion between mutual welding currents. In addition, the inert gas flowing in from the gas inflow port 20c is jetted to the periphery of the pin 5 through the inside of a pedestal 20, a central hole 4a, a horizontal hole 4b, a through hole 3 and an electrode central hole 8a and it can be prevented that the pin 5 is embrittled by absorbing hydrogen produced at the time of welding under the high temperature.

Title: Method and device for decoded moving image signal smoothing processing
Inventor: NAKANO YOSHITAKA
IPC: H04N7/26
Filed: 1987-08-26
Abstract: PURPOSE:To reduce deterioration of a picture in quality due to coding distortion by discriminating between a picture element in a moving block area and a picture element in a still block area, and switching the degree of smoothing of a smoothing filter for each picture element area depending on the result of said discrimination. CONSTITUTION:A picture element area discriminating circuit 104 outputs indentification signals 9 that represent five picture element areas by using a picture element counting value 7 and a moving/still block identifying signal 8. In case of a moving block area, each picture element to be filter-processed is discriminated whether it is a picture element of the boundary or a picture element inside the boundary by using the counting value 7, and the picture elements are divided into two areas. In case of a still block area, whether a moving block neighbors or not is decided by referring to surrounding moving/ still block identifying signals, and the picture elements are divided into three areas. Accordingly, in the smoothing filter 108, the smoothing processing is executed by multiplying the surrounding picture elements and a center picture element with characteristic coefficients.

Title: Dirt detecting device and reproducing device for minidisk
Inventor: ASAKAWA YOSHIYUKI
IPC: G11B7/00
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a minidisk reproducing device which detects dirt affecting reproduction and displays that a sound-skipping and a reproduction impossibility are caused by dirt to the outside by using a dirt discriminating circuit. SOLUTION: The read part 10 of an optical pickup reads out data by following to the track of a minidisk. A servo control circuit 53 controls the operation of the read part 10 and also outputs an off-track signal when the optical pickup is deviated from a track which the pickup following, and a stylus-skipping is generated. A stylus-skipping address storage part 18 stores the address information on position where a previous off-track signal was outputted, and a judging circuit 20 judges whether the stylus-skipping is caused by the dirt of the surface of the minidisk by performing the comparison of the address information of a position where a present off-track signal was outputted based on the position in the storage part.  When the address difference between the previous position and the present position is equivalent to the length equivalent to the one rotation or the several rotations of the track, judging circuit 20 judges that the surface of the minidisk is soiled.

Filed: 1985-09-30
Abstract: PURPOSE:To attain a high speed sorting process that sorts a high-order category group out of a large number of categories by performing an arithmetic process and a process to sort the high-order category simultaneously. CONSTITUTION:Arithmetic circuits 3A and 3B calculate the degree of difference, that is, a distance between a feature value inputted from dictionary memories 1A and 1B and a feature memory 2 that stores the feature value extracted from an input pattern and a dictionary output value at every category corresponding to each feature, and at every calculation of distance in each category, the maximum values of MAX memories 5A and 5B are detected at MAX value detecting circuits 6A and 6B, comparing them with the resulted distance at comparison circuits 7A and 7B, and when the distance value is smaller than the MAX detected value, the distance value is replaced with the maximum value in the MAX memory 5 and at the same time, the category number of the category to which a sort result memory 9 corresponds is replaced, changing the name of the category. Since the addressings of the feature memory 2, the dictionary memory 1 and the MAX memory 5 are performed using a counter circuit 4, a processing time for the rearrangement of the sequence of the categories is not required at all.
