Abstract: PURPOSE:To prevent an aluminum from punching through in a semiconductor device by forming a diffused layer region, then accumulating an insulating film on the overall surface, forming a contacting hole, again accumulating the insulating film on the overall surface, etching the entire surface to remain the side wall of the contacting hole, doping again and then deeply diffusing the contacting hole. CONSTITUTION:After a field oxidized film 2 is formed on a p type Si substrate 1, a polycrystalline silicon gate electrode 4 is formed through a gate oxidized film 3, an n type impurity is doped to form shallow n<+> type layers 5, 6 becoming source and drain, and an SiO2 film 7 is then accumulated on the overall surface. Thereafter, contacting holes 8, 9 are formed on the film 7, and an Si3N4 film 10 is accumulated on the overall surface. Then, the entire surface is etched, and the film 10 is allowed to remain only on the side walls of the contacting holes 8, 9 by utilizing the fact that the film 10 is thick by the stepwise difference. Thereafter, an n type impurity is again doped, to locally form a deep n<+> type layers 11, 12. Thereafter, wiring metal film such as aluminum is covered, source and drain electrode wirings 13, 14 are formed. According to this method, Schottky effect can be prevented.

Title: Instantaneous gas water heater with prevention device against incomplete combustion
Inventor: NISHIYAMA TAKAO
IPC: F23N5/00
Filed: 1980-12-16
Abstract: PURPOSE:To prevent the incomplete combustion from occuring by a constitution wherein a thermocouple for applying reverse bias is jointly provided at the combustion part  of a main burner and the tip of the collecting passage for primary and secondary airs  is pinchingly open at the lower end of a heat exchanger so as to be able to take in  the air in and out of a combustion chamber. CONSTITUTION:At normal combustion, plenty of oxygen for combustion is supplied to  the primary air holes 15 of an inner flame tube 14 and to the secondary air holes 13 of  an outer flame tube 12 by fresh air and two separate flames are produced at the inner  and outer flame tubes 14 and 12. When the concentration of said indoor oxygen becomes low and the generation of large quantity of CO is resulted, the air polluted with  CO enters, through a collecting tube 18 and the collecting passage 17, into the primary  air holes 15 and the secondary air holes 13 and lift the flame off the inner flame tube 14. Accordingly, the electromotive force generated in a thermocouple 10 becomes low  and, as a result, the difference between the electromotive force generated in the thermocouple 9 for applying reverse bias and that in the thermocouple 10 also becomes  small so as to be off a solenoid valve 15 to shut-off the fuel supply. Owing to the constitution as described above, the reliability of the detection of oxygen deficience state is improved and consequently the safety of the water heater is also improved.

Title: Method for controlling active vibration eliminating system
Inventor: ICHIKAWA HIROYUKI
IPC: F16F15/02
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To provide an active control method whereby changes in output in a frequency range wherein a filter factor varies abruptly can be controlled smoothly at low cost. SOLUTION: A data table ROM 66 storing data about the renewal of a filter factor obtained through adaptive control is mounted on the control part 31 of a controller for a mass-produced vehicle M. The filter factor output value ak of an output signal (y) at a predetermined frequency fk in the vehicle to be controlled is compared with a stored filter factor value akmap read from the data table ROM, and if the output value ak is greater than the stored value akmap, a step size parameter μ is subtracted from the output value ak; if the output value ak is smaller than the stored value akmap, the predetermined value μis added to the output value ak, thus performing renewal whenever necessary so that the output value ak is equal with the stored value akmap.

IPC: H01J29/48
Filed: 1983-09-28
Abstract: PURPOSE:To reduce spherical aberration in a main lens system as well as to make the promotion of large caliber attainable, by housing a focusing electrode inside an accelerating electrode being set up inside a neck tube, while forming at least two sets of electron guns inside one accelerating electrode. CONSTITUTION:A electron gun 2 is housed inside a neck tube 1 and provided with a heater 5, a cathode 6, a first control grid 7, a first accelerating electrode 8, a second accelerating electrode 9 and a focusing electrode 10, while all electrodes but the electrode 10 are locked by bead glass 11.

Title: Magnetic reproducer
Inventor: SUGAYA HIROSHI
IPC: G11B5/02
Filed: 1982-10-08
Abstract: PURPOSE:To obtain an excellent reproducing signal without cross modulation by satisfying the relation of lambdaS>g>lambdaL, where lambdaS is the shortest recording wavelength in the 1st signal band recorded on a magnetic recording medium, lambdaL is the longest recording length in the 2nd signal band and (g) is the head gap length. CONSTITUTION:When the wavelength of a signal recorded on a magnetic tape 5 is larger sufficiently than the length (g) of the gap 2, a reproducing voltage proportional to the timewise change of magnetic flux of a coil 4 wound on a core 3 is generated. When the frequency is higher and the wavelength lambda is coincident with the length (g), a magnetomotive force applied to the gap 2 is zero. This phenomenon takes place also when the length (g) is coincident with an integral multiple of the wavelength lambda of the recording signal. The signal having the wavelength lambda shorter than the length (g) is increased at present to a degree not being a problem for practical use. The 1st band in frequencies 0-6MHz is used for the recording of a luminance signal in a video signal and the 2nd band in frequencies 6-12MHz is used for the recording of a chrominance signal in the recording of the magnetic tape, from which the video signal without cross modulation is reproduced and separated by a filter, allowing to reproduce an excellent picture.

Title: Vliw type computer
Inventor: TORISHIMA TAKESHI
IPC: G06F9/38
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To perform failure detection of a computer without using a special test program by comparing the execution result of an instruction by one computing unit with the execution result of the instruction by the other computing unit and notifying it when noncoincidence occurs as a result of the comparison. SOLUTION: An operation that is executed by the other computing unit 2 is performed instead of an NOP instruction in a program that is practically operated by one computing unit 1. An instruction that compares the operation result with an operation result of the unit 2 is inserted at the time of compiling. Therefore, when a program that is practically operated is carried out, a comparator 30 compares an operation result from the unit 1 with an operation result from the unit 2 and outputs a signal showing noncoincidence when the results do not coincide. Then, it is possible to detect a failure of a computer without providing a special test block, running it in background nor running periodically a test program.

Title: Cover equipped with overclamping prevention mechanism
Inventor: YAMANAKA YOSHITAKA
IPC: B65D41/04
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To provide a cover equipped with overclamping prevention mechanism in a container using a screw type socket and the cover as an opening/closing tool in which redundancy of closing is not allowed upon opening and closing the container. SOLUTION: A cover 121 is constructed with a cap 122, a socket 131, and a set of rachets 141, 145, and a protrusion 128 of an outward flange 126 on a lower surface of the cap and a groove in the back surface of the ratchet 141 are connected with each other with play, to which the ratchet 145 including a spring 147 of pressure means mounted thereon is combined. The cap is covered with the socket, and the ratchet and the spring are accommodated in a space hole, and a tip end of a socket cylinder is inserted into a lower portion of a flange 73 of the cap to connect the socket. The cap and the socket are rotated in the same direction with closing operation and ordinary rotational force, while with too strong rotational force any sliding is produced between the ratchets to cause the socket to be idly rotated around the cap with a sound whereby overclamping is prevented.  In opening operation the socket and the cap are rotated together without causing any slide.
