Title: Manufacture of compound semiconductor device
Inventor: IIZUKA YOSHIO
IPC: H01L21/28
Filed: 1981-08-03
Abstract: PURPOSE:To reduce adverse effects of a lattice defect, by a method wherein a protection film is previously formed in the portion on a compound semiconductor substrate where no electrode ohmic contact is required to be formed thereby to localize a denatured layer formed by the subsequent heat treatment. CONSTITUTION:On an n type GaP single crystal substrate 11, an n type GaP epitaxial layer 121 and a p type GaP epitaxial layer 122 are successively grown to produce a compound semiconductor substrate. Then, an Si3N4 film 13 is formed by the CVD method. Subsequently, the portions of the film 13 corresponding to the portions where ohmic contacts are to be formed are removed by etching to form openings 14. Then, an AuBe film 151 is formed on the whole surface of the film 122, and an AuGe film 152 is formed on the rear surface of the substrate 11, then, the substrate 11 is heat-treated. In this heat treatment process, a denatured layer 18 is localized at only the electrode ohmic contact portions, thereby to make it possible to prevent the adverse effects of a lattice defect on the p-n junction in the portions other than the ohmic contact portions of the layer 122.

Abstract: PROBLEM TO BE SOLVED: To display the channel quality of a base station linked at present on a monitor in a mobile station unit of a cellular telephone system where a plurality of base stations use a carrier frequency in common. SOLUTION: A reception section receives a radio signal that is spread- spectrum-processed by a code division multiple access CDMA system, a radio signal from a base station linked by a demodulation section 4 is subjected to inverse spread spectrum processing to separate a pilot channel, a paging channel or a traffic channel.

Title: Apparatus and method for detecting origin position
Inventor: KARUBE HIROO
IPC: G01B21/22
Filed: 1995-05-22
Abstract: PURPOSE: To detect an origin by the simplest constitution of a pair of dogs and an origin sensor which eliminates a special construction even when an operating range of a rotary shaft exceeds 360 deg.. CONSTITUTION: The rotation of a driving source for diving a rotary shaft of a robot or the like is transmitted to the rotary shaft via a mechanism of a fractional acceleration/deceleration ratio. The rotary shaft is rotated in a CW direction or CCW direction in accordance with states of a dog and a sensor for detecting the presence/absence of the dog (steps S1-S4). When a positional relation between the dog and the sensor becomes equal (step S7), the rotary shaft is rotated in the CCW direction, and with the utilization of the fact that a count of pulses of an encoder fitted to the driving source becomes different by a controlling point of view, an origin can be detected at every rotational angular position even when a rotating range of the rotary shaft exceeds 360 deg. (steps S10-S13).

Title: Wire stretching metal wheel
Inventor: OZAWA AKIO
IPC: H02G1/02
Filed: 1991-04-24
Abstract: PURPOSE:To provide a metal wheel for stretching a transmission line with which a long rigid object such as a protector can be passed without causing considerable increase of tension and rotation of the transmission line is suppressed. CONSTITUTION:An arm member 2 having same right and left lengths is journaled, movably up and down, at the lower end of a suspension 1 and wire supporting section 10 comprising a coupling body 5, coupled through a coupling member 7 with a wheel 4 fitted with a tire 14 having two-step-V-groove in the outer peripheral surface, is journaled at each end of the arm member 2. Since the wire is supported by the wheel 4 fitted with the tire 14, the wire surface is protected against damage and since the wire is supported while being wrapped by the elastic tire, rotation of wire is restricted and unstranding thereof is prevented. Furthermore, elastic tire absorbs the step with respect to an object having different diameter and thereby the wire can be stretched with low impact and low noise.

Abstract: PURPOSE:To immediately change a modem transmission speed from a maintenance center machine with respect to a claim of a communication failure by deciding the modem transmission speed during the transmission by the contents of a non-volatile RAM and transferring the data from other equipment to this memory area. CONSTITUTION:A transmission side writes the data inputted from a ten-key input section 5 in a RAM 3. During the transmission, this memory 3 is read, modulated in a modem 6, and transmitted to a line through a line connecting circuit 7. A reception side demodulates a receiving signal in the modem 6 through the line connecting circuit 7 and writes in a non-volatile RAM 4. A procedure of setting the modem transmission speed is set as follows. At first, a CMD indicating that the setting of the transmission speed is performed is transmitted from the transmission side, thereby, the reception side transmits an RSP indicating that it is received, and after waiting for the response from the transmission side, the reception side transmits the data SYC for recognizing the condition of the line. The transmission side transmits the DATA including the modem transmission speed setting data. By this data, the reception side stores in the non-volatile RAM to complete the setting.

IPC: H01L21/822
Filed: 1989-05-16
Abstract: PURPOSE:To eliminate effect of noise of an adjacent switch and to prevent lowering of S/N ratio by separating a well for each MOS-type transistor which constitutes an electrical switching device, by connecting each well electrically by a concentrated diffusion region of homopolarity and by providing a potential to the diffusion region through a metal wiring. CONSTITUTION:A well 4 is separated for each of a plurality of switches which consist of a MOSFET inside a semiconductor device. An adjacent well is connected by a concentrated diffusion region 3 of homopolarity. One end 1 of each switch is connected to one end of each photosensor 15. When light is impinged to the sensor 15 at the time of switch-off, a photo-current of a diode 11 allows a charge of a capacitor 10 to pass through and a potential of the end 1 of a switch is changed. When a switch is on, a charge is injected to the capacitor 10. Change of charge is detected by a resistance 9. Switches are turned on and off successively by a gate control circuit 13 and series-parallel conversion is carried out. Produced charge is absorbed entirely by a region 3, and passed through the metal wiring 6.

Abstract: PURPOSE:To enable to perform an inexpensive and precise measurement by means of a simple constitution, by a method wherein a load detector, located at a lower part of an inner cylinder, detects a change in a buoyancy of a buoyancy-detecting outer cylinder with bottom to measure a liquid level. CONSTITUTION:An inner cylinder 9 is hung down from a base part 5, a hollow outer cylinder 11, whose bottom is closed off, for detecting a buoyancy is positioned outside the inner cylinder 9, and a bottom part 10 of the outer cylinder 11 and the lower end of the inner cylinder 9 are connected to a load cell 12. The outer 11 and the base part 5 are connected together through a rubber seal material 13 so that the buoyancy is not transferred between the two parts. In this constitution, the buoyancy of the outer cylinder 11 changes with the change in a liquid level, and the buoyancy is detected by means of the load cell 12. In this case, the force exerted on the cell 12 proportions to a high h to which the outer cylinder 11 is immersed down, or a liquid level. As a result, if the output of the cell is amplified by an amplification circuit 3 and is indicated by an indication circuit 3, this permits the simple measurement of the liquid level by means of a simple constitution.
