IPC: F16K17/04
Filed: 1989-01-23
Abstract: PURPOSE:To obtain sealability even if small amount of dusts, etc., are engaged and to effectively isolate between high pressure and low pressure sides by providing an annular groove on the end face of a third valve body in a third valve unit and pressing an annular elastic sealing ring partly protruding from the end face. CONSTITUTION:In a third valve unit 9, an annular groove 23 is formed on the end face of a first relief valve 13 of a valve body 22, and an elastic sealing ring 24 is pressed to be engaged. Refrigerant flows via a compressor 2   a condenser 3   a first valve unit 6   a capillary - a tube 4   an evaporator 5   a second valve unit 7   the compressor 2 to perform a freezing action. In this case, a leakage occurs between the third valve body 22 and the first relief valve 13, the quantity of refrigerant flowing from the condenser 3 to the capillary tube 4 is reduced that much, thereby disturbing a normal freezing action. This leakage occurs due to fine dusts in a freezing cycle system circulating together with the refrigerant and being engaged between the third valve body 22 and the first relieve valve 13. Since the fine dusts are sucked by the elastically deformed part of the elastic sealing ring 24 at this time, the sealability of the third valve unit is obtained.

Title: Measuring instrument for butt angle and butt point for welding of electric welded steel pipe
Inventor: OSADA JUNICHI
IPC: G01B21/22
Filed: 1985-01-29
Abstract: PURPOSE:To measure exactly the butt point for welding by calculating the space between the edges of an open pipe in a scanning position with a temp. converter which converts the values measured with thermometers to a temp. distribution and the temp. distribution which is the output of the converter. CONSTITUTION:The outside periphery of the open pipe 8 is scanned at >=2 points of the butt point (V point) for the welding of a work coil 7 and the pipe 8 at an optional space and the brightness at said points is measured by the scanning type thermometers 1, 2. The temp. pattern having peak points is obtd. according to the temp. in the respective measuring positions when the brightness is converted to temp. signal by a temp. converter 3. The peak points of such temp. pattern are the edge corner parts of the pipe 8. The spaces between the peak points of the temp. pattern obtd. by the thermometers 1, 2 are designated as l1, l2 respectively, then the l1, l2 can be calculated at the space between the edges of the open pipe in the position where the pipe is scanned by the thermometers.

Title: Pressure-release guide mechanism in paper pressure device for copying machine
Inventor: KOGURE YOSHIO
IPC: G03G15/00
Filed: 1984-02-01
Abstract: PURPOSE:To simplify both pressure and pressure-release guide mechanism for paper as well as to miniaturize a cassette itself, by turning round a guide arm by means of rocking motion in a guide cam in time of charging or discharging the cassette, while making a pressure lever so as to be shifted to a lower part of the cassette temporarily. CONSTITUTION:In time of charging or discharging a cassette 1, a guide cam 20 being so far stopped at the specified position of a guide taper surface 12b slides downward along the guide taper surface 12b while keeping its attitude of a rocking top dead point P2, and rides on a guide lower surface 12c whereby it keeps its attitude along in an insertion direction of the cassette 1. At this time, since a pressure lever is depressed to a lower part of the cassette via a guide arm 10, a pressure state of the paper by the pressure lever is thus set free.

Title: Flaw inspection method for steel plate
Inventor: YOSHIHARA ATSUSHI
IPC: G01B11/30
Filed: 1993-02-02
Abstract: PURPOSE:To allow the detection of slight and serious flaws and determination of the longitudinal pitch of flaw by connecting a serious flaw detecting circuit having a texture treating function in parallel with a slight flaw detecting circuit and a pitch determining circuit. CONSTITUTION:Surface of a steel plate 2 is scanned with a laser light in the lateral direction and a reflected light is received 3 and sent to a slight flaw detecting circuit A. Signals outputted after gray level conversion are processed by one filter selected by performing differentiation in X, Y and XY directions. The number of pixels in an outputted signal higher than a threshold value is then calculated and a signal representative of slight flaw is outputted when the number of pixels exceeds a predetermined value. On the other hand, a pitch determining circuit analyzes the longitudinal pitch of flaw and detects slight flaw and continuous flaw. A serious flaw detecting circuit B erases a texture signal and following signals on the screen of an image monitor and outputs a signal representative of serious flaw when the number of amplified signals higher than a threshold value exceeds a predetermined value. This method prevents the overdetection of slight flaw and missing of serious flaw at the time of preventing overdetection.

Title: Method and device for coating
Inventor: KUNII HITOSHI
IPC: B05C5/00
Filed: 1987-01-26
Abstract: PURPOSE:To suppress amplification of web fluctuation by subjecting the front side of a bead layer of coating liquids to required pressurization. CONSTITUTION:The web 1 is conveyed without contact by the gas injected from a gas injector 2, by which the bead 10 superposed with the two layers of the coating liquids 8a, 8b is formed on the surface. The required pressure is exerted to the front side of this bead via a filter 13 connected to a pump 14 and a pressurizing box 12. The floating and fluctuating of the web 1 are prevented by a difference between this pressure and the pressure exerted to the rear face by the injected gas, by which the amplification of the web fluctuation by a tension fluctuation, speed fluctuation, etc., is suppressed. As a result, the bead is stabilized and the generation of the uneven coating of the web is decreased.
