IPC: F23D17/00
Filed: 1980-02-15
Abstract: PURPOSE: To make it possible to use selectively the gaseous fuel or liquid fuel, by mounting a means to introduces liquid fuel or gaseous fuel selectively and a means to ignite a mixture of jetted fuel and air.  
     CONSTITUTION: At first gaseous fuel is used when liquid fuel are to be used. On ignition a heat storing wall 4 is gradually heated to a high temperature. When the desired temperature is reached, the feed of gaseous fuel is suspended and instead the liquid fuel is fed by opening an electromagnetic valve and driving a pump. The liquid fuel grop on the outer surface of the greater diameter part 15 of a air guide cylinder 14 through a pipe 23. Then they are scattered to the inner part of the caplike part in the heat storing wall 4. Because the cap 8 is maintained at a high temperature the fuel scattered is quickly vaporized. The vaporized gas fuel are mixed with air by an agitating wheel 18 and jetted through the jet hole. In this state a high voltage is applied between an electrode 26 and a case 1 to let discharge and the ignition is made.

Title: Guidance controller for moving vehicle
Inventor: FUJII YASUO
IPC: A01B69/00
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To properly perform guidance travel control exactly according to an initial target on the basis of the magnetic fields of respective guide lines although the guide lines can easily be installed in the ground by providing a specific current suppressing means. SOLUTION: The guide lines 2b and 2d which are installed in a ridge along a width direction are provided with a band-pass filter 19 which passes only the frequency of currents supplied to guide lines 2a and 2c installed in a ridge along a length direction as a frequency filter which suppress the inflow of the currents, flowing through the guide lines 2a and 2c, through the ground. The filter 19 consists of a resonance circuit constituted by connecting a coil 19a and a capacitor 19b in series and its resonance frequency corresponds to the frequency of the currents. Therefore, even if a current of different frequency flows in from another guide line through the ground, the flow of the current through the guide line is suppressed and the possibility that each magnetic field sensor detects wrong information can be reduced.

Title: Masking agent
Inventor: FUJII YOSHINORI
IPC: C25D5/02
Filed: 1994-02-14
Abstract: PURPOSE:To produce a masking agent having a good characteristic without using chlorinated paraffin as a main component. CONSTITUTION:This masking agent is produced by heat-melting and mixing sufficiently 34g amorphous olefin polymer (propylene/ethylene copolymer) and 66g wax (microcrystalline wax) at 120-130 deg.C. When the wax much more than needed is contained, melt viscosity becomes low and necessary masking thickness is not obtained. Also adhesion is low, and the ground film is cracked not to be used as the masking agent. Besides, the polymer much more than needed is contained, since the melt viscosity of the polymer is high, a masking thickness becomes thick than needed uneconomically. Also, tackiness becomes high to make workability worse. At the time of imparting adhesion at low temp. (<=5 deg.C), the adhesion is improved by adding a commercial adhesion modifier.

The two plate are thereafter pressed by the specific pressure to each other in the edge zone and a UV lamp 30 arranged above the vacuum vessel 11 is switched on. The light thereof transmits a quartz glass plate 14 and is made incident on the UV curable adhesives of the adhesive edge strips 26 to cure the adhesives. As a result, the stable cell is obtd. at the high speed.

Filed: 1980-02-18
Abstract: PURPOSE:To improve precision and to shorten the time of etching by making V grooves for mounting optical fibers and a knock pin on a silicon substrate by anisotropic etching and by reducing the extent of etching for the knock pin. CONSTITUTION:On silicone substrate 8, V grooves for optical fibers 71-7n and a V groove for knock pin 11 are formed by anisotropic etching.

Abstract: PURPOSE: To obtain an information reproducing device, wherein sound interruption and the generation of 'hooting sound' do not occur even when an IP flag is generated. CONSTITUTION: The signal, which is read out of an MD 13, is sent into a decoder 3 through an optical pickup 1 and an RF amplifier 2. The data are sequentially stored in a shock-proof memory 5 through a memory controller 4. In the decoder 3, an IP flag is sent into the memory controller 4 when an uncorrectable SG is inputted. When the IP flag like this is inputted, the memory controller 4 abandons the SG corresponding to this IP flag, connects the data at the front and the rear and outputs the result. Thereafter, compression is released by a data expanding circuit 6, and the signal is outputted from a D/A converter 7 as the music signal.

Title: Field ionization type ion source
Inventor: OKUNUKI MASAHIKO
IPC: H01J3/04
Filed: 1982-02-06
Abstract: PURPOSE:To generate an ion beam with high brightness by forming the flow of an ionized gas passing through the aperture of an electrode body by means of the pressure difference between a vacuum chamber that is connected to a space enclosed by the electrode body through the aperture of the electrode body and said enclosed space, and increasing the pressure of the gas near the aperture. CONSTITUTION:Since an electric field is concentrated on the pin-shaped tip section 2 of pin-shaped members 1 arranged closed to an aperture 5, a part of argon gas passing through the aperture 5 is ionized by an intense electric field and becomes the argon gas ion and then is accelerated by a cathode 18. Since a thus generated argon gas ion forms a high pressure gas atmosphere near the tip section 2 of the pin-shaped members and the gas temperature is so low as almost equal to that of liquid nitrogen, the current value can exceedingly be increased.

Abstract: PURPOSE:To perform torque detection highly precisely without making a noise by equipping between driven axle and driven shaft a planetary friction transmission device consisting of a sun gear and ring gear, and by providing a device which detects torque operating on a driven member via the carrier of the planet gear. CONSTITUTION:Through the drive of driving shaft 1, planet roller 10 is rotated via ring gear 8, but since projecting detection piece 18 of carrier 11 is fixed in contact with stopper 20, planet roller 10 while revolving only on its axis rotates intermediate shaft 4. The rotation is transmitted to driven shaft 2 via cam surface 5. If driven shaft 2 is overloaded, the load is transferred to carrier 11 by pressure spring 6 and corrugated washers 16 and 17 via taper part 9 of ring gear 8 and intermediate-shaft taper part 7, and carrier 11 is rotated against spring 19 to open a limit switch for torque detection pressed by projecting detection piece 18, thereby stopping driving shaft 1. Consequently, the torque detection is maintained with high precision without making noises.

Abstract: PROBLEM TO BE SOLVED: To prevent deposition of native oxide between the surface of a semiconductor and a thin layer by depositing SiC on the surface of a semiconductor exposed simultaneously with etching or during following etching and then forming a thin layer thereon without removing the SiC.

Abstract: PURPOSE:To obtain a magnetic field compensator which won't affect the magnetic environment other than an expected magnetic compensation by differentially utilizing a DC magnetic field generated with a coil. CONSTITUTION:Coils 3a and 3b are arranged on the straight line squarely crossing the vertical line passing the center of a measuring space 4 below the center of the measuring space 4 at the equal distance therefrom to generate a upward vertical magnetic field while coils 3c and 3d are mounted in symmetry with the coils 3a and 3d with the measuring space between the two arrays of coils.
