Title: Distortion removal circuit
Inventor: KAWAI HISASHI
IPC: H04N5/14
Filed: 1986-05-21
Abstract: PURPOSE:To remove distortion such as undershoot, etc. from a video signal by removing the high frequency components from the video signal, and clipping the video signal only at the time the difference between thus generated signal and an original video signal exceeds a prescribed level. CONSTITUTION:In case a video signal whose brightness signal has an undershoot reaching the level of a synchronizing signal as shown in figure (a) is inputted to an input terminal 1, a video signal whose waveform is deformed as shown in figure (b) by attenuating the undershoot is outputted by a low-pass filter LPF to the base of a transistor Tr 15. As far as the transistor Tr 15 does not operate, a video signal outputted from a transistor 9 directly undergoes a resistor 11 and is inputted to a synchronizing signal separator circuit. In the undershoot part shown in the figure (a), the potential difference between the base terminal of the Tr 15 and the output terminal of the Tr 9 i.e. the base-emitter potential difference of the Tr 15 reaches an active level, and the potential of the emitter of the Tr 15 is clipped at a voltage level determined by the voltage of the base of the Tr 15, to be made a video signal free from the undershoot shown in figure (c).

Title: Run-length decoding device
Inventor: TOMITA SATORU
IPC: H04N1/419
Filed: 1982-06-30
Abstract: PURPOSE:To speed up decoding processing and to simplify operation control by controlling a conversion part which converts a run-length value into a fixed- length binary code and a conversion part which converts the output of a buffer memory into data equal to said value in parallel. CONSTITUTION:An unfixed-length code word (a) inputted from a transmission line is converted by the fixed-length conversion part 12 and the code conversion part 13 into a binary code (c) indicating a run-length (RL) value successively. The binary code (c) outputted on bit-parallel basis is inputted to the parallel code buffer 21. An RL reverse counting part 14 reads binary code c' out of the parallel code buffer 21 successively to count the RL value reversely and restores the outputs a data string (d). The parts on both sides of the parallel code buffer 21 are controlled to operate in parallel independently of each other.

Title: Electron microscope having reflecting diffraction device
Inventor: TOMITA MASAHIRO
IPC: H01J37/295
Filed: 1981-07-24
Abstract: PURPOSE:To enable a sample position from which a reflecting diffraction pattern is obtained to be easily determined by previously making the optical axis of an unscanned electron ray, which can be switched by one touch operation, to coinside with the optical axis of a scanned electron ray. CONSTITUTION:The optical axis of an unscanned electron ray is adjusted with an exclusive shaft position setting circuit so that the above optical axis passes the center of a diffraction sample chamber 1. Next, an electron ray is scanned, and the optical axis of the scanned electron ray is arranged in alignment with the center of the chamber 1 by means of a shaft position setting circuit of the scanning mode. Then, a sample 4 is inserted so as to obtain a lowly multiplied image of the entire sample 4 upon the CRT of an absorbed-electron display device. After that, an attachment table 10 is rotated so as to adjust the sample 4 to be parallel to the electron ray. By the means mentioned above, a reflecting diffraction pattern can be easily obtained by carrying out an adjustment by means of fine adjustment knobs 6 and 11 so that the position, on which the reflecting diffraction pattern of the sample 4 is desired to be obtained, coincides with the center of the CRT before thus obtained pattern is returned back to the electron ray.

IPC: G03F7/027
Filed: 1990-05-02
Abstract: PURPOSE:To prevent the degradation of quality due to the addition of sensitizing dye by using polyvinyl carbazole as a binder polymer and a methacrylate compound as a monomer, and incorporating a specific iron-allene complex as a polymerization initiator. CONSTITUTION:The polyvinyl carbazone(PVCz) shown by a formula I is used as the binder polymer, the methacrylate compound shown by a formula II is used as the monomer, and the iron-allane complex which has structure shown by a formula III and initiates reaction even with a visible light beam with 488 nm wavelength is used as the polymerization initiator. In the formula I, (n) shows 600,000 - 1,000,000. Therefore, absorption is exerted in the visible range, but it is extremely small, so a nearly colorless photosensitive material for holography is obtained. Consequently, the gradation of the quality due to the addition of sensitizing dye is prevented.

Title: Beam welding method
Inventor: ASAI JUTARO
IPC: B23K26/21
Filed: 1985-05-29
Abstract: PURPOSE:To increase the operability in welding by providing the projecting bar cutting off a beam irradiating direction at one part of the joining member. CONSTITUTION:The tip of one part of a joining member 1a is worked in a projection taper shape and the tip of the other part of a joining member 1b is made in recessed taper shape. A projection bar 2 is formed by rising from the position of completing theinner face and taper face of the joining member 1b. Or if necessary a groove 9 is formed by providing a projection part 8 further on the projection bar 2. An electron beam is irradiated along the joint face 3 by engaging the joining members 1a, 1b. The electron beam 4 melts the vicinity of the joint face 3 and one part of the projection bar 2 and forms the bead 5 and URANAMI bead 6 on the surface of the tube. The bead 5 penetrating the joint face 3 is intercepted by the projection bar 2 therefore. In case of providing the groove 9 the spatter treating work is disused, moreover. The protection against the beam thus becomes unnecessary and the operability in welding is increased.

The control input of feedback control is variably set so that the difference between or ratio of the total control inputs is set to its desired value. The width of variation of air-fuel ratio due to feedback control is thus reduced to maintain catalyst conversion efficiency in its good state.
