IPC: G01S13/74
Filed: 1984-11-01
Abstract: PURPOSE:To attain high accurate mono-pulse angle measurement by forming a feedback circuit in a multi-channel receiver to detect a calibrating signal and compensate amplitude and phase characteristics. CONSTITUTION:Radiators 11, 12 are arranged symmetrically on the right and left sides about a bore site direction, a horizontal pattern is extracted from two directional antenna patterns and sum and difference patterns are formed by a pattern forming unit 13 and a signal for suppressing a bore site signal and the side lobe response of the sum pattern is generated by a multi-channel receiver 15. A target and its azimuth are detected by a mono-pulse signal processor on the basis of said formed signal and an off bore site signal including angular information is obtained from the 1st target response. A high frequency calibrating signal outputted from a calibrating signal generator 18 through bearing couplers 16, 17 is inputted to sum and difference channels at equal amplitude and equal phase and the detection of the calibrating signal and the compensation of the amplitude and phase characteristics are executed by a feedback circuit formed in a multi-channel receiver 15.

Title: Automatic picture quality correction circuit
Inventor: TAKAZAWA OSAMU
IPC: H04N5/205
Filed: 1989-09-06
Abstract: PURPOSE:To obtain a video image with stable picture quality by decrease a picture quality level of a video amplifier circuit when a level of a preshoot and overshoot is large and increasing the quality level when the level of the preshoot and overshoot is small. CONSTITUTION:When the picture quality of a sent signal is hard (with large preshoot and overshoot), an output of an integration circuit 12 is large and an output of a voltage amplifier 13 is decreased accordingly. Thus, a voltage of a picture quality adjustment terminal 15 is decreased and a gain of the video amplifier circuit of a video amplifier chroma circuit 15 at around 2MHz is lower. When the picture quality of the sent signal is soft (with small preshoot and overshoot), the processing is reverse to the case with the hard signal quality, and the gain around 2MHz is increased. Thus, always stable picture quality video image is obtained regardless of dispersion in the picture quality of the inputted video signal.

Title: Electron beam irradiator
Inventor: HIRAI TERUJI
IPC: H01J37/04
Filed: 1986-09-29
Abstract: PURPOSE:To keep the intensity of a beam to be irradiated on a sample constant as well as to aim at improvement in measuring accuracy and efficiency, by controlling the extent of irradiation beam intensity on the basis of an absorption current on a slit disc. CONSTITUTION:An electron beam B to be emitted out of an electron gun 1 as an irradiation beam is focused by a convergent lens 2 after the beam diameter is throttled by a convergent diaphragm 4. This beam B transmits a slit 7A of a slit disc 7 after the beam diameter is throttled by an objective diaphragm 3, and the irradiation beam transmitting this slit is converged by an objective lens 5, connecting a focal point on a sample S. When irradiation beam intensity to a surface of the sample S is controlled according to an absorption current being produced in this slit disc 7, irradiation to the sample S surface is carried out in a constant period, whereby a detection signal is procurable as a periodic signal. Therefore, no influence is given to measuring accuracy, therefore the irradiation beam intensity for the surface of the sample S is uniformly controllable.

Title: Method for joining metallic material
Inventor: YOSHIKAWA YOSHIO
IPC: B23K1/20
Filed: 1993-09-17
Abstract: PURPOSE:To join metallic materials by brazing with an excellent joining property without using any flux. CONSTITUTION:The metallic materials sealed in a gas-barrier vessel along with an antirust package and 4-10C org. compds. having carboxyl or aldehydic groups and preserved are joined by brazing. The metallic material is extremely simply held by this method at a low cost in the reducing atmosphere almost free of oxygen, moisture and corrosive matter and where a reducing gas coexists to prevent the oxidation of the metal surface, the surface of the base metal is made easily wettable with a filler metal, and hence the metallic materials are joined by brazing without using any flux. Consequently, the residue of a flux is not required to be cleaned off after brazing the cleaning process is simplified, and the cost is reduced.

Title: Variable color light source device
Inventor: TAGUCHI NORIYUKI
IPC: G09F9/33
Filed: 1989-09-07
Abstract: PURPOSE:To substantially make one picture element of one light source by disposing three straight tube-like light sources emitting red, green and blue light beams in a reflection mirror whose base is open and which is shaped to be conical so that the tube axis may make an right angle with the base of the reflection mirror and also disposing a shielding plate for covering the light source on the central part of the opening surface. CONSTITUTION:The inner surface of the reflection mirror 1 shaped to be conical and whose base is open is made of a mirror surface, and the straight tube type fluorescent lamps 2a - 2c disposed in the reflection mirror 1 present the emitted light colors; red, green and blue. And the shielding plate 3 covering the tube end parts of the fluorescent lamps 2a - 2c is disposed on the central part of the opening surface of the reflection mirror 1. When the fluorescent lamps 2a - 2c are turned on, the colors of the light beams emitted from the opening surface of the reflection mirror 1 are mixed and the emitted light colors are optionally controlled. And since the shielding plate 3 is disposed at the central part of the opening surface of the reflection mirror 1, the lamp 2 cannot be directly viewed from a display screen side, the light which can be observed from an external part is only the light reflected on the reflection mirror 1, so that the performance of mixing colors can be improved. Thus, one picture element can be substantially made of one light source.
