Title: Signal reproducing system
Inventor: KAKU TOSHIMITSU
IPC: G11B20/14
Filed: 1993-01-28
Abstract: PURPOSE:To make a binarization possible ane to reproduce a signal correctly by providing with a means for eliminating a retardation waveform by HPF and with a means for correcting the change of a reproducing signal by the sagging of the HPF. CONSTITUTION:A retardation component is eliminated from the reproducing signal by HPF 2 and an output (i) is obtained. On the other hand, an output (n) is obtained by adding a waveform outside a VFO period and the output (j) of a sample-and-hold circuit 7 at an adder 9. The output (n) is equal to the sagged waveform of the HPF 2. The output (n) is subtracted from the output (j) by an adder 8 and a waveform eliminating the sagging of the HPF 2 from the reproducing signal of a recording part is outputted. By inputting this waveform to a waveform shaping circuit, a proper binarization is carried out even when a binarization slicing level is detected during the VFO period.

Title: Combustion condition detecting device and combustion control device for internal combustion engine
Inventor: ASANO SEIJI
IPC: F02D45/00
Filed: 1993-01-28
Abstract: PURPOSE:To provide a combustion condition detecting device which can detect a combustion condition of an internal combustion engine without requiring specific timing control, and with accuracy even in a transient time. CONSTITUTION:Combustion index indicating a combustion condition of an internal combustion engine is obtained by performing multiplication with blocks 13 and 17, while table-searching by means of a block 18, by the use of a representative pattern read from a representative rotation fluctuation table group 10 and a pattern which is a normalized orthogonal system of the representative pattern. Phase difference can be eliminated, accordingly, by utilizing the representative pattern of the rotational fluctuation and its normalized orthogonal system, and obtaining sum of products of them and the rotational fluctuation of an output shaft, when the combustion condition is detected. The combustion condition can be detected without considering specific timing exclusively therefor. By previously setting representative patterns of the rotational fluctuation in every rotational speed, the combustion condition can be easily detected even in a transient time. It is unnecessary to provide an independent means for detecting the transient condition.

Filed: 1985-01-25
Abstract: PURPOSE:To miniaturize an image sensor, and to reduce cost thereof by laminating and disposing a capacitance and a light-receiving element onto an insulating substrate and minimizing the size of the substrate. CONSTITUTION:In a photodiode and a capacitance section 8, a series capacitance is formed by an intermediate electrode 10, a first insulating layer 3 and a first conductor layer 2, and the photodiode shaped from N-type amorphous silicon to which P is doped, non-doped amorphous silicon and P-type amorphous silicon to which B is doped is arranged to the upper section of the series capacitance. A second insulating layer 4 functions as a passivation film for a semiconductor layer 5. In a matrix wiring section 9, the opening diameter of the insulating layer 3 is made smaller than that of the insulating layer 4. Consequently, the sectional shape of a contact hole section 11 can be formed to a stepped shape without increasing the number of processes, thus preventing a disconnection at the stepped section of a second conductor layer 7. Accordingly, since constitution in which a capacitance and a light-receiving element are laminated and disposed onto an insulating substrate is formed, the size of the substrate can be minimized, thus miniaturizing an image sensor, then reducing cost thereof.

Abstract: PROBLEM TO BE SOLVED: To make up a stable atmosphere by an inert gas in non-contact soldering or the like using a laser beam. SOLUTION: The inert gas such as nitrogen or the like introduced from an inlet 1b into an annular blowing pipe 1 is not immediately discharged from blowing holes 1a and the gas pressure within the blowing pipe 1 is risen because blowing holes la are perpendicularly arranged to the inlet 1b. The inert gas is about uniformly blot from many blowing holes 1a, arranged with about equal intervals facing to a processing area A, into the processing area A by this pressure. The gas existing within the processing area A from the first is ejected from gaps g1, g2 arranged between an upper and lower shielding plate 3a, 3b forming the processing area A and the annular blowing pipe 1, and replaced by the inert gas. Furthermore, the stable inert atmosphere within the processing area A is always secured by continuously feeding the inert gas.

Title: Recorder
Inventor: ADACHI MOTOTAKA
IPC: B41M5/382
Filed: 1983-01-31
Abstract: PURPOSE:To decrease the number of exchanging ink films and to extend the service life thereof by constituting the titled recorder wherein the respective ink layers of the ink film formed with the ink layers on both surfaces are respectively used for recording. CONSTITUTION:When a wire 1 is operated by a recording signal, a film 7 is pressed strongly to recording paper 3, and an ink lyaer 7b is stripped from a film base 7a and is stuck selectively in a dot shape on the paper 3. Since the wire 1 consists of metal, the adhesion power of the ink 7c to the wire 1 is much weaker than on the paper 3 and the much more ink 7c than the ink 7b remains on the film after printing. Therefore, if the film 7 is turned over to bring the ink layer 7c opposite to the paper 3 and if impact is given thereon again by the wire 1, the ink layer 7c is thoroughly transferred onto the paper 3. The recording by using both surfaces is satisfactorily accomplished particularly when the ink contg. a pigment as an essential component for the layers 7b, 7c and contg. a transfer rate decreasing agent such as a vinyl chloride/vinyl acetate copolymer or the like is used.
