Title: Device for measuring direct current due to asymmetrical component of alternating current
IPC: G01R31/12
Filed: 1992-03-19
Abstract: PURPOSE:To measure the direct current due to asymmetrical component of alternating current quickly and accurately by providing one band elimination filter, two direct current detecting means and a computing means connected in series in response to the level of the zero-phase current of the input alternating current. CONSTITUTION:When a switch 7 is turned ON a contact (a), the attenuated alternating current signal is passed through a low pass filter 2 to eliminate the alternating current component, and thereafter, the direct current is measured by a microcurrent measuring circuit 3. Next, the switch 7 is turned ON a contact (b), and the alternating current signal is measured by a zero cross time difference measuring circuit 5. At this stage, since a phase difference of the input and the output of the alternating current signal is generated by the attenuation by the band elimination filter 1, the phase difference is corrected by an amplifier phase-shifting circuit 4. Next, a computing processing unit 6 subtracts the direct current, which is measured by the circuit 3, from the direct current, which is measured by the circuit 5 on the basis of the zero cross difference, to compute the direct current generated by the asymmetrical component of the zero- phase current to be measured.

Title: Retiming circuit
Inventor: SHIMIZU NAOFUMI
IPC: H01L31/00
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To obtain a retiming circuit operative at a high speed over 100 GHz. SOLUTION: When a clock light is cast on a light absorptive layer 205, electron-hole pairs are generated to change the carrier density in this layer, causing the characteristic impedance of an electric signal transmission line 102 to be changed and hence the electric signal transmission speed to be changed, thus synchronizing data signals with the clock light. Among the electron-hole pairs generated by the light excitation, the electrons are extracted from a buffer layer 204, an electron running layer 203 and electron extraction layer 202 to extract electrodes 105, 106, while the holes are extracted from a diffusion buffer layer 206 to ground electrodes 103, 104 and the lives of these electrons and holes are short, independent of the recombination life.

IPC: G03B42/02
Filed: 1996-04-17
Abstract: PURPOSE: To shorten working time and to enable efficient image diagnosis by storing compression-processed image data and its code information correspondingly and retrieving the code information of a desired image. CONSTITUTION: An optical disk device 66 compresses the data in the image memory by means of a data compression processor, and stores code information such as a patient's name, patient's ID code, photographed date and storage date together with the data of a lookup table used for the display at that point. The code information is used subsequently at the time of retrieving images. Then, a general diagnosis is made possible by taking out and displaying a separate X-ray film image of the same patient from the optical disk device 66. Diagnostic performance is improved by carrying out two different kind of image processing or picture gray level conversion on two CRT's 64, 65, and by comparing them with the film image on a film viewer 63.

Filed: 1987-04-20
Abstract: PURPOSE:To continuously process instructions without forming a decoding stage by providing the titled device with plural arithmetic means for executing the operation of the same instruction and using the computed result of the preceding instruction as arithmetic data for the preceding instruction. CONSTITUTION:When an instruction is defined in an instruction register 11, an index register number and a base register number out of the instruction are transferred to a general register 15 through signal lines 103, 102, and registers corresponding to the numbers are read out and data are sent through signal lines 126, 127. When the instruction requires address calculation is recognized by decoding the contents of the register 11 by a decoder 12, input selectors 21, 22 for an address adder are controlled through a signal line 116 to select an output signal 126 or 127 from the general register 15. On the other hand, the displacement of the instruction is directly inputted to the address adder 23 through a signal line 105. Consequently, the address adder 23 can calculate an operand address and the calculated address is transferred to a storage unit 2 through a signal line 129 and utilized for reading out an operand.
