Title: Method of inspecting rotary body
Inventor: MORIMOTO KAZUO
IPC: G01N29/27
Filed: 1984-11-16
Abstract: PURPOSE:To enable the titled body to attain highly accurate inspection preventing lowering of sensitivity without stopping rotation of a rotary body by selecting optimum frequency of ultrasonic transmission from speed of rotation of the rotary body to be inspected and set frequency. CONSTITUTION:Speed of rotation of the rotary body 11 to be inspected is detected 12. Optimum frequency for ultrasonic transmission is selected from the detected value and set frequency. An ultrasonic signal of selected frequency is combined 14 with the rotary body 11 and the ultrasonic signal propagated in the rotary body 11 is received 15. Thus, ultrasonic wave is propagated directly to the rotary body 11 without contact, and inspection can be made without stopping rotational movement of the rotary body 11. Further, as inspection is made by ultrasonic wave suitable for speed of rotation of the rotary body 11, lowering of sensitivity due to Doppler effect is prevented and highly accurate inspection can be made.

Title: Input signal read-in device
Inventor: SUZUKI SEIICHI
IPC: H03K17/16
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To effectively remove a fixed-period noise, etc., mixed with an input signal. SOLUTION: Once it is decided that the sampling timing of an input signal is generated (101), a delay time is set next (102). This delay time is set at random on the basis of data stored in a table. Then the input signal is read in (103) after the set delay time is elapsed. Thus, the read of the input signal is delayed at random to effectively remove the influence of the fixed-period noise appearing in the input signal. Further, two successive matches of the read input signal are decided and a majority decision on the signal that has matched successively twice is made to determine the input signal (104). Those processes are performed to effectively remove fixed-period noise, unfixed period node, and superposed noise.

Title: Formation of thin film
Inventor: MIZUNO SHIGERU
IPC: H01L21/285
Filed: 1994-09-09
Abstract: PURPOSE: To improve the surface morphology of a thin film and to provide the thin film with high reflectivity without adversely affecting its film properties such as specific resistance, etc., by plural times repeating a set of stages consisting of a nucleus-forming stage and a W film growth stage in which a fine crystal grain state is maintained at the time of forming a W film with a chemical vapor growth method. CONSTITUTION: In this formation, WF6 is used as the gaseous raw material and SiH4 and H2 are used as the reducing gases at the time of forming a W film on a heated substrate. First, as the initial stage of the film formation, W-crystal nuclei are formed on the surface of the substrate. Subsequently to this first stage for forming the nuclei, the second stage for forming a W film by allowing WF6 and H2 to react with each other is performed and further, the first stage and second stage are altemately repeated to deposit the objective W thin film on the substrate.  Thus, since a new nucleus formation is repeated before the crystal grains of an earlier formed W film are coarsened, each of the crystal grains is maintained in a very fine state even at the time of forming a thicker film and the W film having properties of 9.2μΩ.cm specific resistance, 85% reflectivity and 4.5×10<9> dyne/cm<2> film stress can be formed.

Title: Forging die
Inventor: TSURUTA KUNIYUKI
IPC: B21J13/02
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To restrain the accumulation on the upper portion of the land portion and prolong the life of a die having a land portion at its lower end portion larger in outside diameter than its remaining portion by providing the portion above the land of the die with multiple knurl-like convex portions, when work blanks are formed into a specified shape by cold, warm, or hot forging. SOLUTION: Above a land portion 4 of a die 1, multiple knurl-like convex portions 2 are provided. The diameter connecting the highest points 6 of the convex portion is made smaller than the diameter of the land portion 4. The width 3 of the convex portion is not larger than 1/10 of the outside diameter of the land portion 4. It is desirable to make the convex portions 2 by rolling because it is lower in cost than machining. The die 1 moves from the top dead center to the bottom dead center of the press to process the work blank into a specified shape. When the die 1 is pulled up from the bottom dead center to the top dead center, the land portion 4 gouges the work blank leaving the accumulation on the top of the land portion 4, but the convex portions 2 provided above the land portion 4 prevent this.

Filed: 1986-10-15
Abstract: PURPOSE:To stabilize an image having good quality without grinding a photosensitive layer excessively by holding the surface potential of a cleaning roller above +500V in an image forming device which uses negatively charged toner. CONSTITUTION:The cleaning roller 3 which has proper elasticity is pressed against a photo-sensitive body on the upstream side of a cleaning blade 2 and when the toner which is charged electrostatically and negatively is used, the surface potential of the cleaning roller is held above +500V. The cleaning roller 3 held at the plus potential attracts the negatively charged toner electrostatically to remove fine particles such as paper powder, talc, silicone oxide, metal oxide, pigment, and a charged control agent together with the toner without increasing the pressing force of the roller to the photosensitive body 2. The surface potential of the roller 2 is controlled by kneading and dispersing a material which is charged positively such as a nigrosine compound in a roller material or applying it over the surface of the roller.

Title: Flat filter
Inventor: TANAKA TADAKURO
IPC: B01D63/08
Filed: 1991-09-24
Abstract: PURPOSE:To always, efficiently and sufficiently remove air accumulated in a filter chamber in a flat filter. CONSTITUTION:The space 12k in a filter chamber on the upstream side is preferably very thin, of about 200-300mum thickness. A housing 12a on the upstream side is made of material having spring ability so that it may bend outward by internal pressure generated in the space 12k while pushing out the air 13 from a vent hole 12f to deaerate it. When the upstream side housing 12a is expanded outward together with the internal pressure generated on the upstream side filter chamber space 12k, the peripheral part of an air reservoir 14 gets at the vent hole 12f formed on the upstream side housing 12a, causing the air 13 to be pushed out by the spring force of the upstream side housing 12a, permitting it to be suddenly discharged to the outside.

Title: Galvanizing equipment
Inventor: YANAGI KENICHI
IPC: C23C2/00
Filed: 1988-09-30
Abstract: PURPOSE:To reduce the generation of flaws on a plated article by energizing a magnet with the drossy particles formed in a plating tank at all times. CONSTITUTION:A baud steel 3 to be plated is reduction-annealed in a treating furnace having a reducing atmosphere to activate the surface, then continuously introduced into the plating tank 1 at about 450 deg.C through a snout 4, galvanized through a sink roll 5 set in the tank, and then pulled up. Since the dross particles 6 of the high-melting-point Fe-Zn alloy formed by the reaction of the steel 3 with molten zinc 2 are magnetized, a magnetic field 8 is generated in the tank by a permanent magnet 7 provided outside the tank close to the tank, hence the dross particles 6 are attracted by the magnet, and the dross particles 6 in the vicinity of the sink roll 5 in contact with the steel 3 can be reduced. Accordingly, the chance of the hard dross particles 6 being bitten between the steel 3 and the sink roll 5 is remarkably reduced, and the generation of flaws on the plated article is minimized.
