Title: Manufacture of gaas semiconductor device
Inventor: NIKAIDOU JIYUNICHIROU
IPC: H01L29/812
Filed: 1988-04-27
Abstract: PURPOSE:To prevent the disconnection of a gate electrode as well as the deterioration of device characteristics, by forming a bandlike part where the concentration of boron is distributed uniformly in the direction of a depth, thereby isolating elements. CONSTITUTION:Boron ions are implanted selectively in a GaAs substrate 10 and the boron ions are changed into ion accelerating energy and an ion dose so that the concentration of boron is distributed uniformly in the direction of a depth in an active layer 1 and they perform double ion implantation by dividing implantation of the boron ions in twice. Thus, the bandlike part of an insulator where the concentration of boron is distributed uniformly in the direction of the depth is formed and leak currents are controlled. The aspect of this insulator allows the device to maintain its superior characteristics; besides, its planar structure reduces the disconnection of a gate electrode.

Filed: 1989-04-27
Abstract: PURPOSE:To facilitate the operation of the subject system by performing the updating and saving processes of an input/output file position pointer at the start of the transaction process of a program and recovering the pointer at the occurrence of a program fault. CONSTITUTION:A file position pointer saving means 41 saves the input file position pointer of an input file 2 and the output file position pointer of an output file 3 into a saving area 5 at the start of the transaction process of a program. Then a file position pointer recovery means 42 delivers the input and output file position pointers saved in the area 5 and calls out a VTO (volume table of contents) information updating means 43 to recover the file position pointers in the VTOCs of both files 2 and 3. Consequently, the roll-back operations are automatically carried out for both files 2 and 3 constituted of non-journal order process files.

Title: Method for inspecting semiconductor device
Inventor: AKIYAMA KEIGO
IPC: G01R31/26
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To provide an inspection method whereby nonconformities with the mounted condition of a semiconductor device can be detected easily and properly. SOLUTION: When inspection for functions is initiated by operating a semiconductor chip 20 mounted on an inspection board 40, the surface temperature of a package 18 is elevated by self-heating of, e.g. an internal circuit. The forward voltages of a protective diode are measured before and after the temperature is elevated by the self-heating. The range of compared values of the forward voltages before and after the self-heating of the protective diode which correspond to a proper elevated temperature value is predefined as a reference value for use in determination, and the upper limit of the reference value is compared with the actually measured voltage values whereby excessive temperature rises, i.e., manufacturing (mounting) errors, can be detected.

Title: Filtration
Inventor: ITOU KIYOUJI
IPC: B01D25/12
Filed: 1979-08-22
Abstract: PURPOSE: To provide a low moisture-content filter-sludge through a strong filtration by using the pressure of original liquid to expand filter chambers so that compressing of the adjacent filter chambers is repeated alternately or irregularly.  
     CONSTITUTION: The original liquid is forced from supply pipes 5 into every other filter chambers Sa while stopping the supply to the filter chambers Sb. Since the filter plates 1 are flexible, the filter chambers Sa expand and the chambers Sb are  compressed. The original liquid in the chambers Sb tends to back-flow, but the  original liquid in the chambers Sb pressure rubber membrane valves 6 to block cut  sections 2b and therefore the liquid is not discharged. After a specified period of  time, supplying of the original liquid is stopped to the filter chambers Sa and the  original liquid is supplied from pipes 5 to the chambers Sb which have been compressed. Thus, the chambers Sb expand and the chambers Sa are compressed to perform filtration.

Title: Binarization circuit
Inventor: TODA TOSHIHISA
IPC: H03K5/08
Filed: 1984-05-26
Abstract: PURPOSE:To encode an input signal precisely to a binary value even if the input signal is in a low level and to prevent the input signal from an error due to noise or the like by applying hysteresis to an average value found by an integration circuit to set up the threshold of a comparator. CONSTITUTION:An input voltage VIN is averaged by an integration circuit consisting of a capacitor C2 which is a binarization circuit and a resistor R6 to find out an average value Va and a differentiation circuit consisting of a resistor R2, a capacitor C1 outputs its differentiation signal at the change of the output voltage VOUT of the comparator COM and a resistor R4 feeds back the output voltage VOUT. Hysteresis is applied around the center value Va by the threshold (ref) of the comparator COM on the basis of the feedback. The hysteresis is temporally changed in the reverse direction to the voltage VIN by the output of the circuit DIF at the inversion of the output voltage VOUT. When the level of the voltage VIN is low and noise is superposed to the voltage VIN, the voltage VIN is encoded into a binary value precisely.

Filed: 1985-05-20
Abstract: PURPOSE:To improve operability in terms of microphone sound recording and dubbing sound recording and to prevent howling when a built-in microphone power source rises and falls by connecting a transistor to a built-in microphone signal line. CONSTITUTION:Sound recording/reproducing changeover switches 19 and 20 are connected to the side of a sound recording terminal R. When a built-in microphone control transistor 11 is off, a bult-in microphone transistor 9 is turned on to operate a built-in microphone 1, and an output signal is muted when a monitor transistor 18 is in the on state. When a reproduction detecting switch 27 is turned on, the transistors 11 and 9 are turned on and off, respectively, and the microphone 1 will not act and is made in the dubbing sound recording state. A howling preventing transistor 4 is connected to the signal line of the microphone 1 from the same voltage line controlling the action of the transistor 18. Even when the microphone 1 acts at a low voltage, the operation is switched through the signal line, where by no howling arises.

Title: Small-sized motor and its assembling method
Inventor: FUKUDA YOSHIAKI
IPC: H02K37/14
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To ensure flatness of upper and lower frame end surfaces and facilitate stability management of welding equipment, by sandwiching a plurality of metal segments between close contact end surfaces of the upper and lower frames, applying a current across the frames in the state that the contact area of the frames is kept constant, and fusing a plurality of the metal segments. SOLUTION: Since the contact area of upper and lower frames 2, 3 can be kept constant only by adding new metal segments 4a, 4b, stable resistance welding is possible, in the same end surface forms of the frames 2, 3 as the conventional case. Thereby it can be evaded that the side surfaces of the frames 2, 3 are fused as in the conventional art, and holes and cracks are generated in a welding part. As a result, welding strength also can be stabilized. Labor hour necessary for end surface precision maintenance of the frames 2, 3 for welding and adjustment of welding conditions can be remarkably reduced. Appearance is excellent and resistance to rust is high. Energy efficiency of a resistance welding method is about 80% and superior to a laser light.
