Title: Formation of wiring metallic layer
Inventor: SUZUKI SEIICHI
IPC: H01L23/52
Filed: 1986-08-12
Abstract: PURPOSE:To obtain sufficient resistance to the fracture due to both a stress and an electric current by a method wherein heat treatment is performed to promote the growth of crystal particles at least at one face of a laminated structure made of a material which is produced by doping a metal or an alloy with an impurity for suppressing or promoting the growth of crystal particles. CONSTITUTION:An Al-Si(1%) layer 12 is first applied to an SiO2 layer 11 by means of sputtering. After the Al-Si(1%) layer 12 has been deposited to reach a prescribed thickness value, a target is replaced and an Al-Si(1%))-Zr(0.6%) layer 13 is deposited by means of sputtering. Zr which is contained in the second sputtered layer suppresses the growth of crystal particles during the heat treat ment at the posterior process. As an impurity which shows the action to sup press the growth of crystal particles in relation to an Al-based alloy, Ti or Cu can be used in addition to Zr. The quantity of doping is about 0.01-0.1% for both. As a result, a layer composed of small-sized particles can greatly resist the fracture due to a mechanical stress while a layer composed of large- sized particles can greatly resist the fracture due to an electric current. There fore, it is possible to increase the overall resistance to the fracture.

IPC: B01D29/01
Filed: 1987-07-29
Abstract: PURPOSE:To increase product yield and improve product quality in a coarse grain separation using a screen, by adding a dehydration inhibitor to a high- concn. coal-water slurry prior to the coarse grain separation. CONSTITUTION:A high-concn. coal-water slurry is produced by feeding in appropriate amts. a charge coal from a hopper 1, water from a first tank 2 and a dispersant from a second tank 3 into a wet mill 4, and operating the mill. Added to the high-concn. coal-water slurry (coal concn. : about 60-75%) obtd. in the wet mill 4 is a dehydration inhibitor from a third tank 5 in an appropriate amt. From the high-concn. coal-water slurry, coarse coal grains are separated using a screen 6. A high-quality product which has passed through the screen 6 is collected in a storage tank 7, and the separated coarse coal grains are returned to the wet mill 4 for re-pulverization. At this time, the trouble that fine coal grains do not pass the screen 6 due to the dehydration of the high- concn. coal-water slurry on the screen 6 can be avoided by the action of the dehydration inhibitor. Thus, product yield can be sufficiently enhanced.

Title: Intake pipe in internal combustion engine
Inventor: YAOITA AKIO
IPC: F02M31/135
Filed: 1988-07-28
Abstract: PURPOSE:To make improvements in warming efficiency by forming an intake pipe with a plastic material containing conductive materials, while making an electric current flow into this intake pipe, in the intake pipe for an internal combustion engine which feeds a fuel supply system with air purified by an air cleaner via the intake pipe. CONSTITUTION:When an engine is driven, fuel is drawn out to the inside of an intake passage 3 of a fuel supply system 2, and it is mixed with air flowing in the intake passage 3 from an air cleaner and an intake pipe 9, then this mixture is fed to the engine 1 via an air-fuel mixture conduit tube 8. The intake pipe 9 is made up of a plastic material as a base material in which conductive materials are contained. A driver closes an on-off switch 11, making an electric current flow in the intake pipe 9 at the time of engine driving in the state that an ambient temperature in the engine is relatively low. With this energization, the intake pipe 9 is subjected to self-heating as a whole, making the temperature of the intake pipe 9 go up. Consequently, air in a cold state run past the intake pipe 9 is heated, whereby this temperature upped air is feedable to the fuel supply system 2, thus carburetion in fuel being fed to the engine 1 is improved.

Filed: 1987-07-29
Abstract: PURPOSE:To obtain a multi-frieze picture without moire, etc., and with little picture quality degradation by executing band limitation by a low pass filter so that the frequency of an inputted video signal does not go to more than 1/2 of a substantial sampling frequency even when the multi-frieze image is prepared. CONSTITUTION:A low pass filter 3 having approximately the same band as the inputted video signal, a low pass filter having a narrower band width than a first low pass filter, and a first selector to selectively remove the output of the low pass filter 3 and the output of the low pass filter 4 are provided. The inputted video signal is inputted to the low pass filters 3 and 4. At the time of hard-copying one frame video picture, the first selector 6 selects the low pass filter 3, and at the time of hard-copying the multi-frieze picture, it selects the low pass filter 4. The low pass filter 4 sets the number of frames to an M number in a scanning line direction, sets the number of frames in a direction vertical to this to an N number, (M and N are integers more than 2), and functions so as to limit the inputted video signal to an fs/(2M) or below when a sampling frequency is set to the fs.

Title: Digital sigma/delta modulator
Inventor: NAKAMURA SHINICHI
IPC: H03M3/02
Filed: 1987-07-29
Abstract: PURPOSE:To reduce a signal delay request in a quadratic integration processing by feeding back the output of a coarse-quantizing means to a supplying means, subtracting a feedback signal from a first integrator output and supplying it to a second integrator. CONSTITUTION:An adder 41 and a register 43 part execute the integration processing of a high-order bit. The output of an adder 47 to deal with a low- order bit is supplied to a register 49 and composes an integration circuit, and the carry is supplied to an adder 46. In such a way, the adders 41 and 42 of a first integrator and the adders 46 and 47 of the second integrator are separated by the registers 43 and 44. Consequently, it is enough for a delay in respective adders to be in time to a one clock interval. It is enough that the output of a subtracter 45 is outputted before carries E1 and E2 from the adders of the low-order are transferred, and there is no problem of a timing.

Title: Back projecting device
Inventor: IWAHARA YUKIAKI
IPC: G03B21/62
Filed: 1985-08-30
Abstract: PURPOSE:To eliminate the color irregularity at a device which projects an optical image on the back surface of a screen by providing a Fresnel lens on both surfaces of an incidence member and setting the prism angle of the Fresnel lens on the incidence surface smaller than the prism angle of the Fresnel lens on the projection surface. CONSTITUTION:A projection light beam obtained by enlarging an image on a cathode-ray tube through a lens is projected on the incidence surface of the back projection screen. Then, its incidence surface is provided with such a prism angle thetaIN that the loss of the quantity of light is disregarded and the projection surface is provided with such a prism angle thetaOUT so that the light beam is not reflected totally to constitute the incidence surface and projection surface Fresnel lenses. For example, the prism angle thetaIN is made extremely small, e.g. 2 deg. and the prism angle thetaOUT is made large, e.g. 52.5 deg.. Consequently, the incident light beam RIN' is transmitted through the screen 1 without being reflected totally. Thus, the prism angle of the incidence surface is made smaller than that of the projection surface, so the loss of the quantity of light at screen corner parts is reduced and the color irregularity is eliminated.

Title: Strippable, pressure-sensitive adhesive tape roll for prevention of breaking and scattering of glass
Inventor: OGAWA ETSUO
IPC: C09J133/00
Filed: 1996-07-01
Abstract: PROBLEM TO BE SOLVED: To provide a removable, pressure-sensitive adhesive tape roll for prevention of breaking and scattering of glass which can eliminate a problem involved in a craft tape temporarily used for prevention of breaking and scattering of a windowpane by a typhoon or the like, that is, a problem that when the adhesive strength is excessively high, the pressure- sensitive adhesive is left on the surface of the glass at the time of stripping the tape, while when the adhesive strength is excessively low, a tape roll is spontaneously rewound by the self-weight application work, making it difficult to conduct the application work. SOLUTION: A low-tack acrylic pressure-sensitive adhesive layer is provided on one side of a plastic film. A heavy release agent layer comprising a copolymer composed mainly of a vinyl monomer having a long-chain alkyl group is formed on the other surface of the plastic film. The resultant pressure-sensitive adhesive tape is wound into a roll form. In this case, the high speed unwinding force is brought to 230 to 480gf/25mm to prevent the unwinding of the tape roll by the self-weight. This pressure-sensitive adhesive tape can be easily applied to the surface of a windowpane to surely prevent breaking and scattering of glass, and the tape roll is not unwound by the self-weight during the application work. After the tape becomes unnecessary, the tape can be fully released from the surface of the glass without leaving the pressure-sensitive adhesive on the surface of the glass.
