Patent JP-H0766625-A (JP)
Title: Multi-beam antenna
Inventor: KONDO AKIRA
IPC: H01Q25/04
Filed: 1994-06-14
Abstract: PURPOSE:To improve performance by providing plural pieces of feeder parts constituted of a primary radiator and an auxiliary reflection mirror decided by specific conditions corresponding to respective beam directions. CONSTITUTION:For phase distribution on the opening of a main reflection mirror 1a, since the shapes of the auxiliary reflection mirrors 4a and 4b are decided so as to be uniform inside surfaces orthogonally crossing in the desired beam direction, no distortion is present in any beams. Since the mirror 1a is a parabolic reflection mirror and the mirrors 4a and 4b are decided by the condition of optical path length fixation, amplitude distribution on the opening of the mirror 1a depends on the shape of a sub reflection mirror 2a. Thus, by turning the shape of the mirror 2a to a correction mirror surface, low side lobe type and high efficiency type amplitude distribution can be realized, the antenna becomes high performance to any beams and a manufacturing cost can be reduced since the mirror 1a is the parabolic reflection mirror.

Title: Radar device
Inventor: EGUCHI NORIHIDE
IPC: G01S7/02
Filed: 1978-10-27
Abstract: PURPOSE:To decide the target distance singularly as well as to increase the clutter suppression properties by securing the distance correlation process at the reception time for the low wave angle beam of the electronic scanning array altitude radar by transmitting the two sets of the minor repetition cycle pulses with switching. CONSTITUTION:The low wave angle beam transmits alternately and in switching the pulses of two types of minor repetition cycles 1/T1' and 1/T1'' which cover the short distance rather than the maximum necessary coverage region. Accordingly, the pulse repetition frequency increases to enhance the clutter suppression properties for the moving target indicator filter, and therefore the clutter occurring with the low wave angle due to the ground, the sea level and the like can be suppressed. On the other hand, two types of reception pulses showing virtual target distances Tr' and Tr'' receive the correlation process through the distance correlation circuit. Thus target distance Tr is decided singularly via the equivalent reception pulse of after the correlation and according to the both reception pulses featuring the phases coincided with each other.

Title: Electronic apparatus
Inventor: WADA HIROMI
IPC: H01H50/02
Filed: 1990-05-23
Abstract: PURPOSE:To set the operating characteristic of the apparatus in the title unchanged even if it is heated from the outside, and ensure the sealing property of the apparatus by constituting a pass-through hole provided on a housing by means of sealing it with an elastic film for pressure regulation. CONSTITUTION:A pass-through hole 22, which is provided on the side face of a case 18 that forms a housing 19, is sealed with an elastic film 23 for pressure control that is bonded with an adhesive material. Thus, even if a relay and the like is heated from the outside and the gas in the housing 19 is expanded, the elastic film 23 swells out of the pass-through hole 22 so that the internal volume increases. Therefore, the air pressure in the housing 19 is maintained at a constant level so that neither distortion occurs nor residual stress is produced in the housing 19. Thus, since no residual stress is produced, the operating characteristics can not be changed and also the sealing property can be ensured.

Abstract: PURPOSE:To reflect a light transmitted through a board without receiving by a photodetector on the board by a concave mirror, and input it into the photodetector by forming a recess surface having a light absorption layer of the photodetector as a focus to an incident light from the board on the rear surface of the board of a part formed with the photodetector, and plating the surface of the recessed part to form a concave mirror. CONSTITUTION:If a light having a long wavelength band is incident perpendicu larly to the surface of a board, a light incident on the photodetecting surface of a photodiode is absorbed directly by a light absorption layer (n<-> type InGaAs layer 4) of the photodiode, but a light incident except the photodetecting surface is incident on a GaAs board 1. However, since the GaAs has a wide band gap and is transparent for the light having the long wavelength band, the incident light is introduced to the board 1. However, since the GaAs has wide band gap and is transparent for the light having the long wavelength band, the inci dent light is made to pass through the board 1 to reach a recess mirror portion of the rear surface. The surface of the recess part 10 having the absorption layer as a focus to an incident light passage 9 to the photodetector is plated, such as gold-plated 11 to form a concave mirror.
