Title: Minute-vibration measuring device
Inventor: IZUGAWA KAZUHIRO
IPC: G01H9/00
Filed: 1983-06-01
Abstract: PURPOSE:To measure minute vibrations at high frequencies without receiving electromagnetic effects, by projecting a light beam on a body, which is minutely vibrated, through an objective lens, and utilizing the reflected light from the body. CONSTITUTION:An optical system 3 is fixed to a frame body as a unitary body and provided on body 5, which is minutely vibrated in the directions of arrows. A laser beam from a semiconductor laser 1 is made to pass a beam splitter 2, converged by an objective lens 4, and projected on the body 5. The reflected light from the body 5 is made to pass the objective lens 4 again, and converged on a light receiving element 7 through the beam splitter 2 and a cylindrical lens 6. Meanwhile, the outputs of light receiving pieces 7a-7d are added by resistors 8-13 and an operational amplifier 14. The difference between the sum of the outputs of the element pieces 7a and 7c and the sum of the outputs of the element pieces 7b and 7d is btained by resistors 15-20 and an operation amplifier 21. The outputs are displayed on an oscilloscope 26 through dividers 22-25. Frequencies and amplitudes are measured based on the waveforms on the scope.

Title: Multibeam image forming device
Inventor: KOBAYASHI KAZUNORI
IPC: B41J2/44
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To always adequately form an image regardless of image density by changing a beam pitch in accordance with picture element density in an image forming device using a laser diode array. SOLUTION: An angle arithmetic part 203a arithmetically calculates the angle of an LDA 211 in a subscanning direction with respect to a beam exit direction based on the image density to be recorded. A beam pitch converting part 205 changes the angle of the LDA 211 in the subscanning direction based on the angle arithmetically calculated by the part 203a. The LDA 211 generates two light beams which expose a photoreceptor so as to form a latent image and which are arranged side by side in the subscanning direction. An optical axis direction correcting part 207 corrects the direction of light emitted by the LDA 211 toward the photoreceptor.

Title: Method of decomposing fluorocarbon
Inventor: SUGATA TAKESHI
IPC: B01D53/70
Filed: 1989-04-14
Abstract: PURPOSE:To easily constitute a process of rendering fluorocarbon or fluorocarbon-containing materials harmless and prevent emission of harmful materials out of a system by decomposing the fluorocarbon or fluorocarbon- containing materials inside a high temperature - high pressurized water in a temperature and a pressure (supercritical) condition exceeding the critical temperature and critical pressure. CONSTITUTION:A high temperature - high pressurized water is fed to a reactor together with a fluorocarbon or fluorocarbon-containing material. As the conditions of that time, a temperature exceeding the critical temperature of water, for example, 380 deg.C or more, and a pressure over the critical pressure of water, for example, 300atm or more, are preferred. The feed quantity of fluorocarbon is preferably less than 1/100 by mole ratio to water. When the fluorocarbon is chlorofluoromethane containing no hydrogen, the greater part is hydrolyzed in this reactor, forming carbon dioxide water, and hydrogen halide. The hydrogen halide in the product is neutralized by alkali and made harmless.

Title: Video signal processing unit
Inventor: NAKADA AKIRA
IPC: H04N5/14
Filed: 1988-04-19
Abstract: PURPOSE:To also cause an output waveform to be a low glitch by making the digital data of a same phase and a reverse phase at first to data from a pallet RAM, after that, once holding the data to a latch circuit and arranging the phase from the reading of the data. CONSTITUTION:The value of an Iconst 20 to be supplied from a constant current source is set from an external part so that a gate voltage V101 and a drain voltage V102 of a transistor Q21 can be equal (V101=V102). Accordingly, the current of an output CUT30 in a current source circuit is determined by the switching of the two kinds of the data, which are the input signals of transistors Q31 and Q41 and in mutually complementary relation. The switching levels of the transistors Q31 and Q41 are set to the cross point of rising and falling voltage waveforms for the two kinds of the data of the same phase and reverse phase. Thus, the timing of turning-on and off can be matched for the transistors Q31 and Q41 and the condition of the turning on and off can be made extremely short. Then, the switching can be executed with avoiding the condition of the turning-on and off and the output signal can be caused to be the low glitch.

Abstract: PURPOSE: To simplify the mechanism of deceleration, etc., by providing two threads of different pitches to a shaft turned by a motor for a device to open or close a flow rate valve by shifting a rod in the axial direction by the rotation of the motor.  
     CONSTITUTION: When the stepping power of an accelerator pedal (not illustrated) is lost and the rod 14 is pressed to the right direction by the spring 24 and the lever 4, the stopper 12, along with the rod 14 and the shaft 8, is pressed to the right direction and the switch 22 is turned ON by the lever 21. At this time, when the motor 6 is turned by the computer 5, the shaft 8 is turned while being decelerated by the gears 7 and 9. When the screw 10 is a 0.8 pitched right handed screw and the screw 11 is a 0.7 pitched right handed screw, for example, the stopper 12 and the rod 14 are relatively separated from each other by 0.1mm when turning the shaft 8 to the right and the rod 14 is shifted to the left by 0.1mm. Thus, the throttle valve 2 is opened by as much as a given opening degree.

Abstract: PURPOSE:To maintain an all-weather type horse race track always in a good condition by constituting it with sand on which a composition comprising asphalt, vegetable oil, and fine powder with a specific surface of more than a specified value is applied. CONSTITUTION:A horse race track cushion material is composed of approx. 0.5 to 3.0wt.% of asphalt, approx. 0.4 to 2.5wt.% of petroleum distillate, approx. 0.1 to 0.6wt.% of vegetable oil, and approx. 0.5 to 3.0wt.% of fine powder with a specific surface of more than 3000cm<2>/g, to the weight of dry sand. A mixing is made in a plant within a mixing temperature of 100 to 120 deg.C to keep uniformity. Since oil content with a pour point of below 0 deg.C has a proper viscosity, film formation property and water-resistant property, a strong film is formed on sand particle to prevent the oil content from being flown out due to rain fall, etc., the coated sand particles are adhered and restrained properly and temporarily to each other, to suppress the production of dust without impairing any cushion property of natural sand.

IPC: G06T1/20
Filed: 1989-04-17
Abstract: PURPOSE:To rapidly calculate graphic element data by the small number of processors by dynamically changing the calculation load of the processors. CONSTITUTION:The transfer of a graphic element such as a straight line and a polygon from a coordinate space defined by a user to another coordinate space, coordinate conversion, clipping, or shading is executed by connecting plural processors like a pipeline. The calculation load of respective processors is dynamically changed in accordance with the coordinate conversion, clipping, or shading defined by a user. Thereby, the volume of calculation for all the processors are averaged and the generation of a processor executing no operation can be prevented. Consequently, the graphic element data can be rapidly calculated by the small number of processors.

Title: Manufacture of semiconductor device
Inventor: NAKAGAWA KENJI
IPC: G03F7/095
Filed: 1979-07-31
Abstract: PURPOSE:To maintain a distance between a mask and a copied piece and to enable uniform exposure, by making projections of the second photoresist on the first photoresist on the surface of the copied piece. CONSTITUTION:A positive resist 2 for making a pattern is coated on a semiconductor substrate 1. A negative photoresist 3 is coated on the former resist 2. A mask for the negative resist is used to perform exposure and development to leave dots of the resist 3 on a scribed line on the substrate 1 to use the dots as spacers 4. A glass mask 5 is then adjusted to the substrate 1 to expose the pattern to light. At that time, air is likely to go out and uniform exposure is enabled because the mask 5 and the substrate 1 are kept parallel with each other at a small distance. The mask 5 and the substrate 1 can be easily separated from each other because their tight fitted area is small and air easily goes in between them.
