IPC: H04B7/005
Filed: 1992-01-14
Abstract: PURPOSE: To control an AGC function of a receiver, based on the TDMA to be every close to a proper value at the start of a reception time slot in a radio telephone system. CONSTITUTION: An electric field strength of a signal with power, whose ratio to a power of a signal in a time slot just preceding an actually concerned reception time slot and sent from a base station is measured, and a required gain of an AGC amplifier is calculated based on the measured electric field strength and the AGC gain of the amplifier is set to a value, calculated with respect to the reception time slot time. The electric field strength of the received signal in the received time slot is assumed to be identical to one of monitored signals or calculated by a means for the power ratio.

Title: Level control circuit
Inventor: OWADA TATSUO
IPC: G06F9/48
Filed: 1989-01-11
Abstract: PURPOSE:To enable two level converting processes by a single processing and to halve the processing time by resetting the level flags except the one corresponding to the present level by means of an interruption process suppression flag and attaining the apparent function of a priority level selection circuit. CONSTITUTION:A level flag a-0 is connected to a logical AND circuit a-4 via a data signal line a-5. Then an interruption process suppression flag a-1 is connected to a logical NOR circuit x-3 via a data signal line a-6. The interruption process suppression flags (1-1) - (N-1) are all reset and it is required to suppress the execution of programs corresponding to the priority levels higher than a level (a) in a program executing state after setting the flag a-0. In such a case, the flag a-1 is set. Thus the output of a level flag suppression circuit corresponding to a level Z is reset and sent to a priority level selection circuit. Then the level (a) is executed next. As a result, the level conversion processing time is shortened.

Title: Machine screw clamping checker for cassette
Inventor: KUBOTA KAZUO
IPC: G11B23/087
Filed: 1988-01-13
Abstract: PURPOSE:To decide correctly and in a short time whether a machine screw is screwed up to a prescribed depth or not by detecting the relative displacement of a probe to a moving member and detecting a distance from a reference position up to the head part of the machine screw. CONSTITUTION:A cassette 2 is located in the reference position by a cassette locating means 3, and a probe 7 to be moved in the screwing direction of the machine screw to machine-screw-clamp upper and lower halves is abutted to the head part of the machine screw. A moving member 9 to be moved in the same direction as the probe 7 is abutted to one part of the cassette 2 located in the vicinity of the machine screw, and the relative displacement of both the probe 7 and moving member 9 in a moving direction is detected through the use of a detecting means. A deciding signal to indicate the quality of the machine screw clamping by comparing a detected value from the detecting means with a reference value is outputted by a deciding circuit 10. Thus, whether a machine screw floating condition is in or not, etc., can be automatically decided correctly and, simultaneously, in a short time even when the shapes of the machine screw and a prepared hole are different.

Filed: 1991-01-21
Abstract: PURPOSE:To dispense with labour to repeat adjustment of beam width with every sample, and improve processing efficiency by arranging exclusive inspecting devices respectively for setting a direction of a sample and for detecting an angle of a cut surface. CONSTITUTION:Exclusive inspecting devices 11 and 12 by means of an X-ray are arranged respectively for setting a direction of a cut surface 17a of a sample 17 and for detecting an angle between the cut surface 17a and a crystal lattice surface.

Title: Hetero junction field effect transistor
Inventor: SUZUKI MASAHISA
IPC: H01L21/338
Filed: 1985-01-16
Abstract: PURPOSE:To minimize the leak current flowing through a channel between a cap layer and a gate electrode by a method wherein a cap layer on a gate side is removed by etching process to form a groove. CONSTITUTION:When the sides of ohmic electrode of source, drain are removed by etching process causing a resistance, the element characteristics are deteriorated, therefore overall surface of substrate is coated with resist 19 to open a gate part only. Furthermore when a cap layer 14 on the gate side is etched along wider space, source and drain resistance are augmented, therefore the cap layer 14 is etched utilizing SiO2 layers 18 as spacer layers formed by lifting off the gate part as masks. At this time, an opening on the gate sides may be made around 1,000 Angstrom  by means of making fine gaps between the gate parts by slightly overetching the SiO2 layers 18 as spacer layers.

Filed: 1978-01-23
Abstract: PURPOSE:To avoid the damage of partial reflection mirror even at the high output laser oscillation, by increasing the oscillating efficienty and making stable the output, through the replacement of non-discharge part with the gas weak in the absorption to the laser oscillation light or vacuum. CONSTITUTION:Since the absorption to the laser oscillation light is exposed to the gas or vacuum 12 weak in the absorption at the surface of the laser media 1 of the Brewster window 11, the heating of the mixed gas for the remained non-discharge part 2 partially can be prevented. Thus, by replacing the non-discharge part 2 with the gas weak in the absorption to the laser oscillation light 5 or the vacuum 12, since the absorption loss of CO2 molecules can almost be neglected, the oscillation efficiency can be increased and the output can be made stable, and the damage of the partial reflecting mirror 4 can be avoided at high output laser oscillation.
