Title: Method and apparatus for digitally measuring amount of electric energy consumption
Inventor: RICHIYAADO ERU RONGIINI
IPC: G01R21/133
Filed: 1991-04-25
Abstract: PURPOSE: To provide a digital watt-hour meter which has a more appropriate accuracy and can be manufactured at an allowable cost. CONSTITUTION: A time differential coefficient of a magnetic field generated by a current flowing through conductors 11-12 of a transmission line is measured by magnetic field change rate pickups 16 and 17, instead of measuring the current actually from the conductors 11-12, and thereby a record being proportional to the time differential coefficient of the current is obtained. By using a suitable microcomputer 30, the time differential coefficient of the magnetic field (magnetic field change rate) is expressed by an algorithmic series for expressing a periodic phenomenon, such as a low-order Fourier series, in a stage 40.  The microcomputer 30 converts a mathematically the time differential coefficient of the current expressed by the algorithmic series and measured values of voltage from the conductors into a power record and computes an approximate value of the quantity of electric power consumption (stages 41-43). Moreover, the power records are summed up, in the stage 43, so as to obtain a numerical value being proportional to the quantity of energy consumption.

Title: M series code generator in spread spectrum communication system
Inventor: HAMATSU MASAHIRO
IPC: H04J13/10
Filed: 1985-06-05
Abstract: PURPOSE:To attain communication with high secrecy regardless of use of a M series code by including a latch means for setting the state of flip-flops connected in series and changing the content one after another. CONSTITUTION:The content of the latch 3 is outputted from a latch 2 to control AND gates AND1-ANDn and feedback lines h1-hn generate a code II. As a result, the code II is outputted newly from the M series output terminal by a clock pulse after the A. On the other hand, a strobe pulse STB 1 is used as the interruption pulse to a microprocessor and the interruption pulse is used as a trigger and the microprocessor prepares the code III to be generated next. When the strobe pulse STB 2 is inputted, the code output is switched from the II to the III similarly. Since the type and phase of the M series code output are changed one after another, the communication with high secrecy is attained regardless of the use of the M series code.

Title: Vapor phase growing method of gallium arsenic layer
Inventor: NAKAI AKINOBU
IPC: H01L29/73
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To enable a GaAs layer to be doped with In by growing a GaAs layer doping with C and In in a specific temperature region. SOLUTION: In order to vapor grow a GaAs doped with C and In using halogenated carbon (CBr4 , etc.) and TMIn as doping materials, if the growing temperature (substrate temperature) is assumed to be about 600-650 deg.C, the growing rate is lower and not to be doped with In. However, if the growing temperature is lowered than this temperature, the growing rate is made higher approaching to the growing rate of a non-doped GaAs layer while increasing the doped In amount. When this growing temperature is made higher than 580 deg.C, In will be hardly doped while the growing temperature is set up in the region of 400-580 deg.C since the membranaceous quality is lowered at the growing temperature lower than 400 deg.C.  Through these procedures, the GaAs layer can be doped with required amount of C and In thereby enabling the characteristics and reliability of an electronic element to be enhanced.
