Title: Gathering detecting unit of leaked fluid
Inventor: MIZUOCHI AKINORI
IPC: G01N1/10
Filed: 1979-06-11
Abstract: PURPOSE: To detect leakage of kinds of oil into cooling water of a thermal exchange using, for example, cooling water in the initial stage without distinction of liquid and gas, by separating, storing and detecting leaked fluid gathered by a specific means.  
     CONSTITUTION: When gas is leaked from thermal exchange 9, most of leaked gas is stopped by gathering orifice 17 and is led into detector main body 1 together with cooling water from sample extracting tube 18 through valve 14. Gas is separated by partition plate 5 and is emitted from ventilator 3 to air and so on, and only cooling water is discharged from outlet 4. Since ventilating orifice 8 is very smaller than inlet orifice 7, leaked gas cannot be exhausted partially from ventilator 3 and is stored in the upper part of room A in the inlet side and becomes air pressure or more to lower the water level in room A. When lowering of the water level is detected by level detector 6 to issue a signal, leakage accidents of thermal exchange 9 can be reported.

Abstract: PURPOSE: To shorten time for direction change and prevent a carriage from stopping by a method wherein the number of slits is counted in a direction change and a speed control is not performed during the counting.  
     CONSTITUTION: When a carriage CA performs reciprocating movements, a flip-flop F2 is set since an output signal line lBB of a back counter BC counting the number of slits in a direction change becomes "1" in a drive to the backward direction. A clock from a signal line lCP is not input to a speed control circuit SC since a signal line lF is "0" then because of the drive to the backward direction, and a speed control is not performed. When the specified number of slits is counted in the back counter BC, the flip-flop F2 is reset to start the speed control.

IPC: B29C45/20
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To prevent a cobwebbing phenomenon when a molding side resin is separated from the molten resin in a nozzle by a method in which porous metal is attached integrally to the periphery of metal which forms a nozzle hole, piping which makes compressed air or vacuum pressure work on the porous metal is installed, and the piping is opened/closed selectively. SOLUTION: Porous metal 23 such as sintered metal is attached integrally to the periphery of metal 22 which forms a nozzle hole 21 to constitute a nozzle 20. Piping 24 which makes air pressure or vacuum pressure work and a solenoid valve 25 which opens/closes the piping 24 selectively are installed to the porous metal 23. The valve 25 is made nonexcited, and a resin material is injected into a metal cavity. Slightly before the completion of the injection, when the valve 25 is made excited, compressed air from the piping 24 passes through the pores of the metal 23 and cools the nozzle hole 21 to solidify the molten resin in the inside. When the product is taken out, the nozzle 20 is brought back to separate the resin between the product side and the nozzle 20 without causing a cobwebbing phenomenon.

Filed: 1991-04-05
Abstract: PURPOSE:To reduce the noise like distortion by using a noise reduction means consisting of a limiter circuit which allows a short-amplitude value to pass through and a filter circuit which extracts data having a space frequency compo nent in a high band by delay and addition/subtraction. CONSTITUTION:A noise reduction circuit 18 is provided after discrete cosine inverse conversion. Picture element data is inputted to the circuit 18 from a terminal 21, and one data is sent to a delay circuit 22, and the other is sent to a noise extraction path consisting of an HPF 25 and a nonlinear limiter 26. The limiter 26 limits the amplitude of a high-band signal Y passing the HPF 25 and has such nonlinear characteristic that only the short-amplitude component is allowed to pass as a noise Z. The extracted noise is eliminated from the original picture signal, which passes a delay circuit 22 to cancel the delay of the processing time, by an adding circuit 23. Since the distortion is corrected by noise reduction after restoration to picture element data, the visual effect is increased.

Filed: 1983-04-26
Abstract: PURPOSE:To enable to block the unstable action caused by photo noises by providing a black insulation layer on a transparent substrate supporting a photo receiving element in the side facing the element by excluding the part necessary for light incidence and conductor connection. CONSTITUTION:A black insulation layer 8 is printed and formed on the back side of a glass substrate 4 after print-forming conductor patterns 5. The insulation layer 8 has windows in the region 41 opposed to the photosensitive part 2 of a photo receiving element 1 and in the regions 42 of existence of conductor parts 51 for connection of the bump electrodes 3 of the photo receiving element, respectively, thus producing the dimensions not covering the connection part 52 of the conductor part 5 to outside. Such an insulation layer 8 is easily formed with e.g. black glass paste by normal thick film technique. By the existence of the insulation layer 8, the incident light 6 reaches the photosensitive part 2 through the window 41, but does not reach it from the other part. Even when the light 7 is reflected from said part 2, it strikes the balck insulation layer 8 and causes no irregular reflection.
