Title: Hard brittle material cutting method by means of fixed abrasive grain wire saw
Inventor: OGAWA HIDEKI
IPC: B24D3/00
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To provide excellent surface roughness by running a wire saw at a wire speed within a specific range. SOLUTION: In cutting by a wire saw based on fixed abrasive grain, more excellent surface roughness is provided in comparison with that by a free abrasive grain method when a diamond grain diameter ranges from 30 μm to 60 μm and a wire speed ranges 1000 m/min to 2500 m/min. The reason of this is assumed that a cut face in a workpiece is lapped in a brittle mode in machining by free abrasive grain while cutting is carried out in a ductile mode in the fixed abrasive grain wire saw at the high wire speed. At a low speed below 1000 m/min, a cut depth of the abrasive grain is increased and machining in the brittle mode is carried out mainly, so that excellent surface roughness cannot be provided. Contrarily, at a speed above 2500 m/min, the abrasive grain does not bite a hard brittle material but slips on its surface and tends to be deterred from cutting.

Title: Manufacture of heterojunction field-effect transistor
Inventor: ENOKI TAKATOMO
IPC: H01L21/338
Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To improve the operating speed and breakdown voltage of a field- effect transistor by independently, highly accurately, and uniformly controlling the side etching quantity at gate recessing time on source and drain electrode sides by performing a process for removing a highconcentration impurity layer in the area corresponding to a gate electrode with an etchant. SOLUTION: After the entire surface of a multilayered structure is coated with a resist material 1-11, opening sections are formed through the resist material 1-11 by using a resist pattern having openings on a drain electrode 1-9, a source electrode 1-8, and a gate area 1-10-1 between the electrodes 1-9 and 1-8. At the time of forming the opening sections, the area of the opening 1-91 on the drain electrode 1-9 is made larger than that of the opening l-81 on the source electrode l-8. In such a state, a cap layer 1-7 exposed in the gate area l-10-l is selectively etched by using an etchant containing an oxidization reduction agent and having a lower etching speed against a barrier layer 106 and a higher etching speed against the cap layer 1-7. Then an HFET is completed by vapor-depositing and lifting-off a gate electrode 1-10.

Title: Output voltage controller of a.c. generator
Inventor: ARAI MAKOTO
IPC: H02J7/14
Filed: 1991-09-13
Abstract: PURPOSE:To distribute the output of an a.c. generator to an AC load and a DC load without any loss by allowing a ramp voltage short circuit to detect only a negative half wave of a.c. voltage and by allowing a ramp voltage control circuit to detect both positive full wave and negative full wave. CONSTITUTION:The load voltage detected by a ramp voltage short circuit 5 is actually lower than the one detected by a ramp voltage control circuit 4. Therefore, even if the operating voltage and the short-circuit voltage are set the same and a timing to switch from full wave to half wave is deferred, the ramp voltage short circuit 5 does not work. This means that full wave can be supplied to the AC load 3 until the a.c. generator 1 comes to fully generate. The ramp voltage control circuit 4 and the ramp voltage short circuit 5 never work at the same time. Consequently, the a.c. output of the a.c. generator 1 can be appropriately distributed to the AC load and the DC load 13 such as a battery 8 without any loss.

As a result, the intrusion of the vapor in the open air can be prevented, and the corrosion of the aluminum conductive film for wiring located on a semiconductor integrated circuit can also be prevented.

Title: 1h delay correcting circuit
Inventor: KOMATSU NAOKI
IPC: H04N5/91
Filed: 1988-10-21
Abstract: PURPOSE:To output an input video signal, which is delayed for 1H rather than a reference signal, in any cases and to improve flexibility by selecting a selector to send an output, for which the input video signal is delayed by 1H, and the input video signal according to synchronous relation with the reference signal of the input video signal. CONSTITUTION:An input video signal VSI and the input video signal, which passes through a delay circuit to give the delay of 1H, are selected by selectors 6 and 7 and sent. Then, phase difference between the input video signal VSI and a reference signal RFS is discriminated. When the input video signal VSI is synchronized with the reference signal RFS, the output of delay circuits 4 and 5 is selected by the selectors 6 and 7. When the input video signal VSI is delayed by 1H, the input video signal is selected. Thus, a 1H delay correcting circuit can correspond to any cases that the input video signal VSI is synchronized with the reference signal RFS or delayed by 1H. Then, the flexibility is improved.

Filed: 1992-09-07
Abstract: PURPOSE:To prepare a resin molded product clearly colored with crystal glitter by the method in which oriented scale-shaped fine particles are dispersed in a resin and the mixture, after being cured or solidified and then pulverized, is mixed randomly with a resin composition. CONSTITUTION:Pattern forming resin particles 1 with an average particle size of 0.3-2.0mm are prepared by the method in which oriented, glittering scale- shaped fine particles 2 with an average particle size of 5-100mum are dispersed in a resin and the mixture, after being cured or solidified, is pulverized.
