Title: Radar apparatus mounted on airplane
IPC: G01S13/42
Filed: 1988-04-14
Abstract: PURPOSE:To shorten not only the highly accurate observation time of topography but also the avoiding time thereof, by respectively mounting receivers to respective element antennas and performing signal processing in parallel to obtain multibeam. CONSTITUTION:The high frequency signal received by (N) element antennae 1 is parallel processed from the receivers 3 respectively mounted to the antennae to be outputted as digital complex video signals. (N) multibeams are formed at every frequency component by a digital multibeam forming means 4 to be stored in a memory 5 and inputted to a multibeam angle measuring means 6. The sum and difference signals of two adjacent beams outputted from said means 4 are divided by the divider and angle converter of the means 6 to be converted to the arrival angle of a radio wave. By the use of this angle data and the range data obtained from the digital complex video signal, the altitude difference between the center axis of each antenna 1 and the obstacle corresponding to each sampled range is calculated by an altitude difference detection means 7 to observe topography.

Title: Liquid crystal display element
Inventor: WATANABE TOSHIO
IPC: G02F1/133
Filed: 1988-04-13
Abstract: PURPOSE:To prevent the generation of the unpacked part in a liquid crystal cell which arises from a temp. change of operating environment and to prevent the change in the inter-substrate spacing of the liquid crystal cell in an effective display region by providing a buffer chamber which is partitioned by the same material as a sealing material and where a resin for adhering the inside part does not exist to a region excluding the effective display region. CONSTITUTION:This display element is constituted of an outside circumferential seal 10, upper and lower plastic or glass substrates 11, polarizing plates 12, spacers 13 for controlling a gap, the resins 14 for sealing the inside part, oriented films 15, transparent conductive films 6, a seal 17 which partitions the display part and the buffer region, a liquid crystal phase 18, an injection port 23, and a sealant 24. The cell is constructed without purposely subjecting the buffer region provided in the cell to internal adhesion to allow a minor volumetric change. The buffer region is thereby bulged by as much as the increased volume of the liquid crystal at the temp. near the upper limit of the operating temp. range so that the uniform gap control is enabled without affecting the display part. The buffer region shrinks by as much as the decreased volume of the liquid crystal at the temp. near the lower limit of the operating temp. range. The generation of the unpacked part of the liquid crystal is thus prevented.

Filed: 1981-06-18
Abstract: PURPOSE:To manufacture a cathode structure which shows an excellent emission characteristic and in which a base metal plate is efficiently attached to a cathode sleeve without receiving any adverse influence of thermal or mechanical effect. CONSTITUTION:A cathode sleeve 11 made of an Ni-Cr alloy is put in a wet hydrogen furnace with high temperature so as to blacken the surface of the sleeve 1 by selectively oxidizing Cr contained in the alloy.

Title: Functional trimming of hybrid integrated circuit
Inventor: TANAKA MICHINORI
IPC: H01C17/24
Filed: 1988-04-14
Abstract: PURPOSE:To perform extensive functional trimming with high accuracy, by functionally trimming resistors disposed at appropriate intervals continuously along the longitudinal direction of an electrode which is formed linearly on an insulating substrate. CONSTITUTION:An electrode (conductor) 1 is provided linearly on an insulating substrate and resistors (R1) 2 and (R2) 3 are formed continuously along the electrode on one side of it in such a way that respective resistors are out of contact with each other. When it is required to improve the accuracy of functional trimming, it is preferable usually to make the resistance value in one resistor higher than that of the other resistor. As to functional trimming, trimming of the resistor (R1) 2 is performed, first of all, so that errors which are short of the desired functions may remain within the range of + or -5-10%. Further, fine adjustment is carried out after trimming the resistor (R2) 3. This approach makes an area where the resistors are formed small and changes the value of resistance extensively and thus, functional trimming is performed to attain the goal of electrical characteristics with high accuracy.
