Title: Noise eliminating circuit
Inventor: SAITO AKIHIRO
IPC: H04N5/21
Filed: 1992-07-06
Abstract: PURPOSE:To eliminate the noise of a video signal in response to a noise level by detecting noise in the noise component in a non-signal block for a vertical synchronizing signal period and integrating the noise level by an integration circuit. CONSTITUTION:An input signal 102 is inputted to a synchronizing signal generating circuit 2, a timing signal 103 of a non-signal part is generated, a sampling circuit 3 extracts a vertical synchronizing signal missing part from the signal 102 based on the signal 103. An integration circuit 4 integrates a non-signal part of the vertical synchronizing signal and a coefficient generating circuit 5 outputs a noise level 104. On the other hand, the signal 102 is given to a Y/C separation circuit 6, from which a luminance signal 105 is outputted. A BPF 7 extracts a high frequency component 106 having the noise component. A nonlinear processing circuit 9 processes the signal 105 and inputs a nonlinear processing signal 107 to a subtractor circuit 10 and a noise elimination output signal 108 is obtained via the subtraction of the signal 107 from the signal 105.

IPC: H01M12/08
Filed: 1986-07-29
Abstract: PURPOSE:To make it possible to get a small and compact size cell, by forming projections to reduce the upper side space of a gas phase chamber in the framework of a unit cell, and keeping the liquid level in the equibrium pressure at the current value responding to selfcorrosion below the penetrating hole of an ultraviolet ray fluorescent lamp. CONSTITUTION:Square projections 12 to reduce the upper side space of a gas phase chamber 6 in the framework 1 of a unit cell are formed at both sides of a penetrating hole 10 of an ultraviolet ray fluorescent lamp, setting the space not to disturb the H2-Cl2 reaction. Therefore, by keeping the liquid level at the equiribrium pressure at the current value responding to the self-corrosion below the penetrating hole of the ultraviolet ray fluorescent lamp, the electrolyte mixing between the unit cells can be prevented. Consequently, the cell can be made in a small and compact size.

Abstract: PURPOSE:To improve the sound absorbing property of a sound absorbing material in the zone of low frequency, while inhibiting its clogging with tar or soot in exhaust gas, by using a metallic porous body as the sound absorbing material for the exhaust muffler of an internal combustion engine, crushing its surface and then forming a thin film thereon. CONSTITUTION:As a sound absorbing material for noise caused by exhaust gas from an internal combustion engine, the foamed or porous sintered body of a metal or alloy such as Ni, bronze, Fe-Cr, Fe-Ni-Cr or Fe-Cr-Al is used as a sound absorbing substrate, its surface is crushed by a grinder, and a thin film is formed thereon. The thickness of the thin film is controlled at 5-50mu, and its sound absorbing property in the zone of low frequency can be improved as compared with a known sound absorbing material by making the thickness larger within said range. By the presence of said thin film, the clugging of the sound absorbing material caused by the invasion of tar or soot in exhaust gas into its small holes is eliminated so that its sound absorbing property is not deteriorated.

Title: Sampling system for video signal
Inventor: MUTO MASAYUKI
IPC: H04N5/91
Filed: 1985-08-14
Abstract: PURPOSE:To obtain a sampling without damaging the resolution of a video signal by generating a pulse string, phase-locked with a picture element clock signal and having the frequency of 1/N-fold, generating N-set of pulse strings in which each phase is shifted by the frequency of integer-fold and sampling them in N times. CONSTITUTION:Color video signals R, G and B outputted from a CRT display 1 are sampled at the speed of 1/N of the frequency against an original picture element clock signal synchronized with a recovered horizontal synchronizing signal HSync, and the same horizontal synchronizing section is sampled with sampling clock signals Sp1, Sp2 and Sp3 which are the N-set of pulse strings in N times at the phase shifted by the frequency of integer-fold against the original picture element clock while shifting a sampling position equivalent to the share of the frequency of the original picture element clock signal, and transferring them in order to a buffer memory 3. Thereby, despite the sapling at a sampling rate is slower than the rate of the original clock signal, a picture data having the same resolution as sampled by the picture clock signal itself can be obtained.

Title: Actuator
Inventor: ISHIKAWA KAZUMASA
IPC: G11B7/09
Filed: 1985-08-13
Abstract: PURPOSE:To make an actuator thin, small-sized, and low-cost by supporting a lens holder to which an objective lens is attached so that it is symmetrical in 180 deg. rotation with respect to the optical axis. CONSTITUTION:A pair of supporting members 5A and 5B are arranged in such relations that they are superposed on each other when they are rotated at 180 deg. around an optical axis O. Recessed parts (groove parts) are formed on sides of positions, which are symmetrical in 180 deg. rotation with respect to the optical axis O, of a lens holder 4, and a pair of tracking coils 7A and 7B having the same shape and focusing coils 8A and 8B having the same shape adjacent to said coils 7A and 7B are fixed to these recessed parts. When a current flows to coils 8A and 8B, the force which moves the lens holder in the direction of an arrow F perpendicular to the surface of a disc acts. Since an actuator 1 is symmetrical in 180 deg. rotation with respect to the optical axis, higher resonance is suppressed and dimensions in the radial direction, the tangent direction, and the vertical direction are shortened for a disc 6. Thus, the actuator is made small-sized and thin.
