Abstract: PURPOSE:To suppress the dispersion in luminance in a III-V compound semicon ductor element having the hetrojunction by depositing a III-V three-component compound on a III-V compound semiconductor substrate whose carrier density is kept at 2.0-3.5 X10<19> atom/cm<3> by liquid-base growing. CONSTITUTION:The carrier concentration of a III-V compound semiconductor substrate for epitaxially growing a group III-V compound is limited to 2.0-3.5 X10<19> atom/cm<3>. A GaAs substrate 1 wherein the specified carrier concentra tion is kept is inputted into a reaction tube. After gas substitution, the tempera ture is increased to 900-1,000 deg.C. This state is maintained for 30-120 minutes. A growing source is uniformly dissolved. Then, the temperature is decreased at the constant speed. Growing solution is brought into contact with the sub strate 1 in the order of a (p) type or an (n) type. Liquid-phase epitaxial growing is performed, and a (p)-type GaAlAs layer 2 and an (n)-type GaAlAs layer 3 are deposited. A pellet for a III-V compound semiconductor light emitting element is completed after specified steps. Thus, the dispersion of luminance is decreased to about a half. The element can be utilized in the dot matrix which requires the constant luminance.

Title: Field effect transistor and manufacture thereof
Inventor: SAKURA NAOKI
IPC: H01L29/47
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To provide a field effect transistor, which can reduce parasitic capacitance between the gate electrode that gives a large effect on the frequency characteristic and the substrate on the side of the drain-electrode arranging region and has the T-shaped gate electrode that can assure reliability furthermore. SOLUTION: The lower part of a T-shaped gate electrode 54 is made to be a source-side insulating film on the side of a thin-film source-electrode arranging region and a drain-side insulating film 66 on the thick-film drain-electrode arranging region. Thus, the effective aspect ratio of an opening part 53 is made small, and a metal film is completely embedded there. Therefore, there is no risk to gaps being generated in a gate electrode branch part 59, and a parasitic capacitance Cgd on the side of the drain-electrode arranging region can be further suppressed to a lower value.

Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To accurately show a magnetic north without making a watch thicker by arranging a permanent magnet showing a magnetic north in an outer periphery area on the side of a movement. SOLUTION: A watch 1 has a minute pointer 4, a movement 2 jointed to a time pointer 6 and a crystal 8 fastened to a glass flange 10. A cover is formed on the back of a case with a case band 12. A bipolar permanent magnet 16 fixed to a shaft 18 to be rotatable around the rotational axis 20 has a limited magnetic axis vertical to the rotational axis 20 and a fixed direction indicator 24 to shows a magnetic forth. A holder 22 to store the magnet 16 and the shaft 18 is fitted to the case band 12 in an outer periphery area on the side of the movement 2. The magnet 16 is therefore arranged in an outer periphery area on the side of the movement 2 between a character board 26 and the cover on the back of the case. The indicator 24 is arranged at the same height as the time pointer 6 between the character board 26 and the crystal 8, and the minute pointer 4 is passed over the indicator 24.  The watch 1 thus accurately shows a magnetic north without increasing its thickness.

Title: Electronic counter device
Inventor: NAGASAKA TOSHIO
IPC: G06M1/27
Filed: 1986-08-14
Abstract: PURPOSE:To prevent a CPU from malfunction at the time of the runaway of the CPU and to protect data in an EE-PROM by permitting the CPU to write data only when specific data are sent. CONSTITUTION:In case of writing data for the number of prints in the EE- PROM (electrical erasable programmable read-only memory) 4, a write control circuit 16 controls the EE-PROM so as to permit it to write data only for an allowable period. Specific data are sent to a write control circuit 16 through an address bus 5 and also sent to the EE-PROM 4 prior to the writing of data for the number of prints. Since the EE-PROM is constituted so as to be permitted to write data only when the specific data are sent, data writing in the EE-PROM is inhibited when a situation such as the runaway of the CPU 1 due to noise e.g. is generated, so that data writing in error can be completely removed and the data in the EE-PROM 4 can be surely protected.

Abstract: PURPOSE:To always allow the stable vapor deposition of reflecting films by forming steps between the non-heat generating parts and hat generating parts of the heaters for vapor deposition constituted of BN consisting of the non-heat generating parts and heat generating parts for forming the reflected films of optical disks. CONSTITUTION:The heaters 1 for vapor deposition having an approximately rectangular section constituted of BN are constituted of the non-heat generating parts 1e, 1f and the heat generating parts 1d and the steps 7 are formed between the non-heat generating parts 1e, 1f and the heat generating parts 1d. Recessed grooves 2 (about 1mm depth) are formed in the heat generating parts 1d and Al 4 is inserted therein. The Al is heated and melted by the heaters 1 to form the reflecting films of Al on the disks 3a to 3r. The Al 4 overflowing from the recessed grooves 2 evaporates gradually while sticking as flow Al 14L, 14R of the heat generating parts to the right and left walls of the heaters 1. The inflow of the flow Al 15F, 15B flowing out in the longitudinal direction of the recessed grooves 2 into the non-heat generating parts 1e, 1f is simultaneously prevented by the steps 7. The heat generation control stable each time is executed in this way and the stable vapor deposition of the reflecting films is executed.

IPC: G06F12/16
Filed: 1984-09-12
Abstract: PURPOSE:To avoid full system down by generating a module down signal when there is an inconsistence between all ROM test data and compare check data. CONSTITUTION:When all of ROMs are abnormal, a module down signal 28 is generated from a module down signal generator 27.

Title: Electromagnetic wave shielding material
Inventor: MASUDA MIKIO
IPC: B32B15/04
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To improve electromagnetic wave shielding effect by integrally laminating a carbon powder layer on a metal sheet having conductivity, via insulating sheet material. SOLUTION: Electromagnetic wave shielding material 1 is formed by laminating a carbon sheet 2 on a metal sheet 4 having conductivity, via a thermal fusion welded insulating film layer 3, and integrating them into a single body by heating and pressing. The carbon sheet 2 bonds and clamps fine carbon powder 2c composed of a kind of charcoal called 'Binchotan' between an upper unwovern fabric 2a and a lower unwoven fabric 2b. As the metal sheet 4, a aluminum foil is used. The texture of white carbon like 'Binchotan' is finer than black carbon, and the white carbon has dense fine holes and is superior in conductivity, so that electromagnetic wave shielding quality is superior. When the white carbon is combined with the aluminum foil 4, electromagnetic wave shielding effect which is far lager than that of the addition of both shielding effects can be realized.
