Title: Short backfire antenna
Inventor: NUMAZAKI TADASHI
IPC: H01Q19/185
Filed: 1980-10-08
Abstract: PURPOSE:To achieve an antenna with short backfire characteristics easily with a simple construction, by incorporating an impedance matching element, small reflection plate and dielectric constant, and inserting the assembly in an opening of waveguide. CONSTITUTION:A dielectric substance cone frustum 7 is made of a dielectric substance having low dielectric constant and loss, and a small reflection plate 6, irises 5a, 5b are vapor-deposited on a circular plane 8 and rectangular solid. Since the dielectric substance is located at the front part of the opening of waveguide, the size of iris is decided taking into account the effect of impedance. The frustum 7 incorporated with the plate 6 and the irises 5a, 5b and the supporting stand is inserted to the opening 4 and fixed with a dielectric substance screw, allowing to manufacture a number of antennas with arranged short backfire characteristics with matched impedance, simple construction and less number of processes.

Title: Contour correction circuit
Inventor: ABE HIROCHIKA
IPC: H04N1/409
Filed: 1989-06-05
Abstract: PURPOSE:To obtain excellent correction effect by using a signal just after and just before the start so as to replace a signal changing at a contour part with them. CONSTITUTION:A video signal input A inputted from an analog input terminal 10 is differentiated by a differentiating circuit 2 and a waveform B is obtained by taking the absolute value of the differentiated signal. Moreover, a waveform C is obtained by differentiating the waveform B by a differentiating circuit 4. The waveform C has a positive value from the change start point of the signal till the middle of the contour (before the displacement) among the video contour of the video image and has a negative value from the middle till the end point of the change (after the displacement). The signal is compared with a prescribed threshold level shown in dotted lines in the waveform C. The waveform C is detected by a waveform shaping circuit S to obtain detection signal waveforms D, E and when the positive value is discriminated from the contour part by using the waveform D and the negative waveform E, the position of the contour and the width are coded and the result is recorded in a memory 6 together with a video signal from a delay circuit 12 as contour detection information. Thus, color blurring and fog are improved.

Abstract: PURPOSE:To reduce biased abrasion, deterioration of the frequency characteristics, running failure of a medium, and a variation of an output level, by forming a magnetic head by a dummy block consisting of an Fe-Ni compound alloy within a specified composition range, and a core. CONSTITUTION:A magnetic head 1 is formed, for instance, by storing cores 2, 2' constituted of an amorphous magnetic alloy thin plate, and a dummy block 3 constituted of an Fe-Ni compound alloy, in a shielding case 4.

Title: Laser light-emitting device
Inventor: MASUDA SHIGEFUMI
IPC: H01S5/14
Filed: 1986-06-19
Abstract: PURPOSE:To obtain synthetic beams, spectra of which extend over narrow zones and which has stable frequency and a high output, by converging outgoing beams from a plurality of laser diodes by a parabolic mirror, returning transmitted beams from a slit plate fitted at a focus to parallel beams again and extracting output beams from an external resonator. CONSTITUTION:Parallel outgoing beams P1, P1 reflected by first parabolic mirrors 21 by all laser diodes 11 are projected to a second parabolic mirror 22, and reflected by the mirror 22 and converged to a focus F for the mirror 22. A third parabolic mirror 23 having the same focus is also fitted, and a slit plate 24 is set up at a confocus, thus forming Fraunhofer diffraction. Emitted beams P2 transmitted through the slit plate 24 are converted into parallel beams P3 by the third parabolic mirror 23, and applied to an external resonator 25. Consequently, outgoing beams do not pass through a lens system at all, and are applied to the external resonator 25. thus narrowing the zones of spectra. Selection frequency at that time is determined by the slit of the slit plate 24. That is, the width of the slit is decided properly, thus fixing the frequency of output beams at a desired value.

Filed: 1989-06-02
Abstract: PURPOSE:To attain an effective reinterruption processing in accordance with the state of a CPU by instructing a waiting time via the CPU when a reinterruption is carried out. CONSTITUTION:An interruption answer discriminating circuit 113 discriminates whether an interruption is accepted or not. If not, the circuit 113 discriminates whether a reinterruption is requested or not. If so, the circuit 113 starts a reinterruption processing to a control circuit 115. Thus the circuit 115 issues an instruction to an interruption control circuit 111 to start the transfer of the interruption after a time designated by a parameter and based on the contents of an answer parameter receiving circuit 114. Then the circuit 111 carries out an interruption to a CPU via a common bus control circuit 110. Thus it is possible to attain a highly efficient reinterruption process in accordance with the state of the CPU.
