Title: Dot printer
Inventor: IWAKI TAKAHISA
IPC: G06F3/12
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To obtain a dot printer enhanced in throughput as a whole by printing one line at once when a time continuing a part with calculated printing density or more does not exceed a long level durable time and printing the same over a plurality of times when exceeds. SOLUTION: The endurable time of a power supply circuit 16 becomes short when a current supply time at a time of the driving of a head pin is long (the impact of the head pin is strong) but becomes long when the current supply time is contrarily short (the impact of the head pin is weak). Therefore, in such a case that the number of black dots same in density (necessary current value) is continuous in one line when the impact of the head pin is weak, the power supply circuit 16 is endurable even if the continuous time of black dots is long and, therefore, one line is printed at once. The number of times capable of printing one line at once can be increased and the whole throughput of a printer is enhanced.

Title: Manufacture for surface acoustic wave element
Inventor: EHATA YASUO
IPC: H03H9/145
Filed: 1981-08-19
Abstract: PURPOSE:To decrease a deviation of characteristics, by making the amount of side etching of electrode pattern on a piezoelectric substrate uniform. CONSTITUTION:An electrode pattern of an interdigital electrode 12 and grating reflectors 13, 14 is etched, and lattice-shaped short-circuited fine wires 15 are formed by etching a thin metallic film to be the electrode pattern so that the electrode pattern corresponding to each surface acoustic wave resonator can be surrounded. A pair of comb-type electrodes forming each of the interdigital electrode 12 are connected with the wires 15 and short-circuited via the wires 15. After the etching process is finished and resist is removed, the short-circuited fine wires 15 of a piezoelectric substrate 11 are cut off with a dicing method or the like as shown in one-dot chain lines to be split to individual surface acoustic wave resonators. In the process, since the pair of comb-type electrodes constituting the interdigital electrode 12 can be separted electrically by taking the cutting width larger than the line width of the wires 15, correct operation can be attained.

Title: Formation of selective oxide film
Inventor: MITSUI KENJI
IPC: H01L21/762
Filed: 1980-09-16
Abstract: PURPOSE:To prevent the generation of a bird's beak as well as to obtain a high integration by a method wherein an oxide film pattern is provided in a selective oxide region, and after a nitriding film has been selectively formed by heating a substrate in NH3 using the oxide film as a mask, a selective oxidizing treatment is performed. CONSTITUTION:The prescribed pattern, consisting of a thermal oxide film 6  (600Angstrom ) is formed on the substrate 1. Then, the above is heated in the NH3 atmosphere of 1,100 deg.C and the nitriding film 7 (1,300Angstrom  in thickness, for example) is formed in such a manner that it is deeper than the oxide film by 200Angstrom  or more. Subsequently, an oxidizing treatment is performed in the atmosphere of steam of 1,100 deg.C, for example, and an oxide film 8 of approximately 6,000Angstrom  is selectively formed on the substrate through oxide film 6. Through these procedures, as the nitriding film 7 is directly covering the substrate 1 and functioning as an oxidation-resistant mask, the generation of the lateral spreading (bird's beak) on the selective oxide film 7 can be prevented. Besides, the oxide film 6 can be selectively oxidized by removing it after a nitriding treatment has been performed.

Filed: 1994-05-20
Abstract: PURPOSE:To safely convey a scrap without bringing it directly contact into a rubber belt with its sharp corner by placing an underlaying material of a raw material, etc., evenly on a belt conveyor and conveying the scrap not selected on it. CONSTITUTION:At the time of continuous conveyance of a large amount of a scrap for a large blast furnace, etc., there is a trouble of a sharp corner of the scrap sticking into a belt, damaging the belt and tearing it. Contact of a scrap 13 with a belt 2 can be prevented by raising a movable horizontal carrier roller 16 to support a central lower surface of the belt 2 at a part to place the scrap on it upward by a hydraulic cylinder 17, smoothing an accumulating shape of a raw material 3 without a sharp corner and placing the scrap 13 on it. It is desirable that the raw material 3 used as a protective layer is powdery or granular as iron ore. It is possible to convey the scrap to a furnace top charging apparatus without specially processing the shape of the scrap, selecting the scrap and damaging the belt conveyor.

Title: Method and device for detecting interference in fm signal
Inventor: FUJITANI IKUSHI
IPC: H04B1/10
Filed: 1994-06-13
Abstract: PURPOSE:To discriminate a degree of interference disturbance with high sensitivity based on the detection of a DU ratio regardless of simple equipment configuration by detecting the reciprocal of envelope modulation of an FM object wave subjected to interference disturbance as the DU ratio (D/U). CONSTITUTION:An envelope detector 2 detects the envelope waveform of an FM object wave subjected to interference disturbance and a D/U representing a degree of interference disturbance is directly obtained from a divider 8. When an FM modulation wave is taken over, since a reception electric field strength is increased by, e.g. 3dB or over, the output of a 1st comparator 16 and the output of a 2nd comparator 18 are given to an AND gate 22 to obtain take-over information. When the level of a disturbing wave is higher than that of the object wave, the DC component corresponding to a received electric field strength is applied to a 3rd comparator 20 to detect the increase in the reception electric field strength. When the take-over information is outputted, the take- over of a broadcast program is prevented by replacing a usual STL channel with other channel.
