Title: Memory system
Inventor: TAKATSUKA KOICHI
IPC: G06F12/08
Filed: 1994-03-24
Abstract: PURPOSE:To attain a fast access to a main memory without deteriorating its performance by sending data to the main memory after synthesizing the data so as to give the higher priority to the data sent from a bus master than the write-back data sent from a cache memory. CONSTITUTION:When a bus master 104 excluding a CPU applies a write operation to the modified line of a cache memory 102, a data synthesizing circuit 105 synthesizes data so that the higher priority is given to the data sent from the master 104 excluding the CPU than the data sent from the memory 102, and writes the data of higher priority in a main memory 103. Therefore, the data can be written just by giving a single access not twice to the memory 103. Thereby, it is possible to have a fast access to the memory 103 without deteriorating its performance.

Title: Activation maintenance system for device
Inventor: AIDA KOUICHI
IPC: G06F3/00
Filed: 1991-02-26
Abstract: PURPOSE:To add and replace a device without a bad influence upon a computer by supplying power to the interface circuit of the device before connection and controlling the signal output by the supply voltage for connection. CONSTITUTION:Before a connector 3 is connected, a voltage in a prescribed range is given from a battery 9 to a bus output element 8 to make the device controllable. When the connector 3 is connected, an external supply voltage is applied to the bus output element 8 from a bus line 2 through a diode 10. An output element control circuit 11 monitors the external supply voltage, and this circuit 11 inhibits output of a signal from the bus output element 8 until this supply voltage reaches a normal value to indicate the completion of connection of the connector 3. Thus, a bad influence upon another device and the computer is prevented though the device is connected to the bus line without turning off the power source of the computer main body.

Title: Array type infrared sensor
Inventor: AJISAWA AKIRA
IPC: H01L27/146
Filed: 1991-02-26
Abstract: PURPOSE:To obtain a sensor in which the number of picture elements is large and whose resolution is high by suppressing a crosstalk between the picture elements at an array type infrared sensor. CONSTITUTION:Element isolation grooves 7 are formed between individual photodiodes 6 which have been formed on a p-Hg0.8Cd0.2Te layer. In addition, substrate electrodes 10 are formed in the groove parts. Since photocarriers generated in the p-Hg0.8Cd0.2Te layer 4 cannot pass the element isolation grooves 7, it is possible to suppress a crosstalk in which incident positions of infrared rays correspond to picture elements in a one-to-one manner. In addition, since the substrate electrodes are formed in the grooves, the potential of the individual photodiodes is stabilized and an irregularity in characteristic among the picture elements is reduced.

Filed: 1988-03-10
Abstract: PURPOSE:To minimize the area occupied by a resistor adjusting pattern and to obtain two different increments from a single pattern, by providing a discontinuous resistance resistance adjusting pattern and a resistance value non- adjusting pattern having different length of development from each other by bending patterns zigzag with each other. CONSTITUTION:Bent patterns 4a and 5a having pattern loops bent inwardly so as to form recesses are provided respectively in a discontinuous resistance value adjusting pattern 4A and a resistance value non-adjusting pattern 5A. In this manner, there is no useless space in the pattern loops and the overall dimensions of a resistor adjusting pattern 6A can be decreased. The end point of trimming is changed to the rear part from the center, so that some of the patterns are cut previously. Accordingly, even if the final pattern is bridged, it has no effect on any other pattern. Comparing the case in which the patterns are cut in the direction as indicated by the arrow A with the case in which they are cut in the direction of the arrow B, increments of resistance values obtained therein are different from each other since the left-side and right-side patterns 4A and 5A have different lengths of development.

Title: Digital signal recording circuit
Inventor: WAKUMURA SHINICHI
IPC: G11B5/09
Filed: 1985-03-19
Abstract: PURPOSE:To compensate a high frequency shortage of a reproducing system by providing a recording compensating circuit for bringing a modulating signal to incomplete differential processing, and an analog switch for obtaining a recording current signal by switching alternately an output of this circuit and a reference potential, and synthesizing the modulating signal and a clock signal by analog processing. CONSTITUTION:A waveform of each part becomes a recording current whose high frequency has been emphasized by a recording compensating circuit 21. That is to say, a modulating signal (a) is cut with respect to its DC portion by a capacitor C1 and a voltage of a resistance R6 becomes a waveform (c) of positive and negative V/2 centering a reference potential, and this voltage passes through an incomplete differentiating circuit consisting of resistances R7, R8 and a capacitor C2, by which a voltage of the resistance R8 becomes a waveform (d) having a spike voltage at rise and fall points of a pulse. Also, this voltage is multiplied by a clock signal by an analog switch 22 through an impendance buffer amplifier consisting of an operational amplifier OP1 and resistances R9, R10, and a recording current waveform (e) which has been emphasized at rise and fall points of the modulating signal is obtained in an output of the analog switch 22. In this way, the recording density can be improved by compensating a high frequency shortage of a reproducing system by a recording system.
