Title: Field effect transistor and manufacture thereof
Inventor: IIYAMA MICHITOMO
IPC: H01L29/812
Filed: 1984-01-30
Abstract: PURPOSE:To achieve the improvement in Schottky barrier effect and that in thermal and electrical stability simultaneously by performing ion implantation of the elements which will become impurities doped in Al after vapor deposition of Al which will become Schottky barrier gate electrodes. CONSTITUTION:A GaAs semiconductor layer 2 is grown on a semiinsulating substrate 1 and a source electrode 3 and a drain electrode 4 are formed selectively. The resist layer 5 the desired part of which is exposed is formed on a surface of the layer 2. An Al layer 6 as a Schottky barrier gate electrode is formed by vapor deposition. Oxygen which will become the doped impurity in the layer 6 is ion-implanted, after which the unnecessary Al layer is removed by liftoff technique. Then the improvement in Schottky barrier effect can be contrived by accelerating the speed of vapor deposition when fabricating the Al gate electrode 6. Also, the requirements for improvements in performance and reliability can be satisfied simultaneously by increasing the doped impurities in the vicinity of the electrode 6.

Title: Optical integrated circuit
Inventor: HAYASHI SHIGERO
IPC: H01L27/14
Filed: 1988-01-29
Abstract: PURPOSE:To easily integrate a circuit with simple structure by providing a photodetector which holds the electrooptic effect of an opening/closing means for controlling the passage of light from a light source, a switch means which controls the potentials of the opening/closing means and photodetector, and a sense part which generates a signal according to whether or not there is the passing light. CONSTITUTION:When a write signal 1 is inputted, a current flows to a photodetecting element 3 to pass light 9 through a capacitor 7 applied with a high electric field, and the passing light 14 is incident on a photodetecting element 5, which continues to supply a current, thereby holding an on signal. When a write signal 2 is inputted in this state, on the other hand, a photodetecting element 4 turns on, and consequently the light is cut off by the capacitor 7 which is not applied with the electric field any more and the passing light 14 does not enter the photoelectric element 5, thereby holding an off signal. A bit holding part is so constituted that photodetecting elements and capacitors with electrooptic effect are in 1:1 proportion. Consequently, the integration is easily attained with the simple structure.

IPC: B26B19/04
Filed: 1988-01-29
Abstract: An electric shaver wherein the motor housing carries a separable frame for confinement of the cutter and the frame carries a separable casing for an apertured foil which overlies the cutter in assembled condition of the shaver. The frame has a window which is adjacent one side of the cutter and serves for insertion of the casing so that the latter can be attached to or detached form the frame only when the frame is separated from the motor housing. The coupling between the frame and the casing has complementary male and female coupling elements which are designed to confine the casing to movements at right angles to the longitudinal direction of the motor housing. The latter carries a reciprocable slide for a trimmer which can be moved to several positions with reference to the apex of the foil but remains in the general plane of the slide.

Abstract: PURPOSE:To produce ethanol economically and efficiently, in high yield and selectivity, by reacting CO with H2 in the presence of an Rh-Mn catalyst, etc., and an Fe catalyst. CONSTITUTION:Ethanol is produced by reacting a mixed gas containing CO and H2 at a CO/H2 volume ratio of 0.1-10 at 150-450 deg.C and 0-350kg/cm<2> pressure at a space velocity (the ratio of charged feed gas to volume of the catalyst) of 10-10<6>H<-1> in normal state (at 0 deg.C and 1atm), in the presence of a catalyst obtained by supporting Rh and Mn, or Rh, Mn, Ir and/or Li on a carrier and a catalyst obtained by supporting Fe on a carrier. The catalyst can be prepared e.g. by dissolving RhCl3 and MnCl2 in ethanol, immersing a calcined and deaerated silica gel in the solution, distilling out ethanol to dryness, and activating the residue with a geseous mixture of H2 and N2 to obtain an Rh-Mn/SiO2 catalyst.

Abstract: PURPOSE:To enable confirmation of the position of a division on a dial plate in a continuous modification mode using a unit pulse and thereby facilitate modification by a system wherein a unit pulse generating means and a delay time generating means operate alternately when the continuous modification mode is set. CONSTITUTION:When a continuation signal Pk is inputted, a delay time generating means 39 makes a timer operation ended, and after a prescribed time T passes, a modification restart signal Ps makes five unit pulses reset in a target hand position storage means 33. Then, an operation of unit pulse generation and an operation of the delay time generating means 39 are conducted alternately and thereby a continuous modification mode wherein the unit pulses having an interval of the prescribed time T are outputted continuously is effected. In the continuous modification mode, an hour hand 4 operated in a stepped manner continuously stops at the position of a month division only for the prescribed time T, and therefore an operation of a push button 17 can be canceled at the position of the month division aimed to be modified.

Title: Allotting method for sounding channel and assigner
Inventor: TAMURA HIDEKAZU
IPC: G10H1/18
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To prevent such unnaturalness that playing is interrupted at the time of switching a sounding channel by allotting a sound in the order of sound which has the maximum masking effect among sounding sounds to a new music sound from a sounding channel being sounded. SOLUTION: When new key-on is detected, a detecting section 21 checks sounding states of all sounding channels, when all sounding channels are being used, the detecting section 21 instructs an operation section 22 to operate the masking effect of each sound being sounded. The operation section 22 computes the masking effect of all sounding channels based on this indication, and a sound in which masking effect is largest is obtained from a sounding channel being sounded. A sounding channel obtained by the operation section 22 is released, and allotted to a music sound newly sounded by an allotting section 26. Therefore, when sounding instruction on new music sound is issued at he time of sounding of all sounding channels, a sounding channel being sounded of a sound of which the influence on audience is least is released, and allotted to a new music sound.
