Filed: 1998-10-12
Abstract: PROBLEM TO BE SOLVED: To manufacture a long sized and small diametrical pipe by preliminarily stranding plural extremely small diametrical round pipes to form a stranded pipe and reducing the diameter of a large diametrical round pipe into which the stranded pipe is inserted. SOLUTION: Extremely small diametrical round pipes 7 are preliminarily stranded to form a stranded pipe 8, which is inserted into a large diametrical round pipe 9. A perforated pipe 11 is obtained by applying a prescribed diametrical reduction to the large diametrical pipe 9 into which the stranded pipe 8 is inserted. When working is executed in such a method, extremely small diametrical round pipes 10 are only deformed into a little flat shape within the perforated pipe 11 i.e., the large diametrical round pipe, and small holes are not surely collapsed and surely secured. Also, a twisted band plate wherein a band surface is twisted in order to form small holes within the large diametrical round pipe 9 is used, diameter reducing is applied to the large diametrical round pipe 9 into which the twisted band plate is inserted, and whereby the perforated pipe 11 is manufactured.  Also, when the perforated pipe 11 is manufactured by applying diameter reducing, desired elongation of the line length is obtained and a long sized perforated pipe 11 is obtained.

Title: Flow rate regulating device
Inventor: KUBOZONO SHIGERU
IPC: G05D7/01
Filed: 1996-10-09
Abstract: PROBLEM TO BE SOLVED: To provide a flow rate regulating device to perform a flow rate regulation without being influenced by the fluctuation of a feed pressure from a feed source. SOLUTION: By bringing a solenoid 55 into an ON-state, the upper stream part of a valve element 49 is escaped from the intermediate region of a containing chamber 40 and a portion between a flow rate regulation portion 42 and the intermediate region inlet of the containing chamber 40 is opened and a small hole 35 is opened. Since water in a first pressure chamber 22 flows through the small hole 35 to a secondary pressure chamber 11 and a second pressure chamber 24, a working force from a vertical direction is exerted on a pressure reduction valve 13. The pressure reduction valve 13 is pressed down and supply of water from a supply water inflow passage 9 to a supply water outflow passage 41 is started.  When an amount of energization to a solenoid 55 is varied, the area of an annular opening determined according to a distance between a portion 42 and an intermediate region inlet is varied, and an amount of water supplied from a containing chamber 40 to the supply water outflow passage 41 side is controlled. When a supply water pressure is fluctuated, a pressure reduction valve 13 is vertically moved and inflow of water through the supply water inflow passage 9 to a gap 12 is disconnected and connected, whereby as a result, a working force in the secondary pressure chamber 11 is constantly controlled regardless of the fluctuation of a supply water pressure on the supply water inflow passage 9 side and an amount of water supplied to the supply water outflow passage 41 is stabilized.

Inventor: TORII TOMOFUMI
IPC: G03D13/00
Filed: 1987-11-18
Abstract: PURPOSE:To reduce the cost and size of the recorder by disposing an exposing base coated with paints of plural kinds of colors via an image sheet on the imaging position of an original image and utilizing the reflected light from the surface of the exposing base. CONSTITUTION:The columnar exposing base 12 coated with the paints of plural colors is disposed via the image sheet 10 to the imaging position 15 of the original image. A rotating mechanism to be driven by means of a piece of actuator is provided on the exposing base 12. This mechanism is capable of positioning the points of the desired colors to the imaging position 15. The light once passed through microcapsules 10a is, therefore, reflected by the surface of the exposing base 12 if the exposing base 12 is disposed via the imaging sheet 10 to the imaging position 15. Since the paints of the colors of plural kinds are applied on the surface of the exposing base 12, the microcapsules 10a are reexposed by the reflected light of the color positioned to the imaging position at that time. The color tone is shifted toward yellow if said light is yellow. The cost and size of the recorder are thereby reduced.

Title: Angle-operating mechanism
Inventor: SHIONO KENJI
IPC: G01B21/22
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To easily obtain a highly accurate angle signal without raising mechanical accuracy of an angle detector, by eliminating a bit shift even when an accurate angle detection signal varies large compared with a rough angle detection signal. SOLUTION: In formation of a bit shift is obtained from more significant three bits (ABC, DEF) of overlapping nine-bit signals. More specifically, if the bit shift is present between the overlapping three bits (ABC) and (DEF), a correction signal is obtained on the basis of the bit shift information at the precise side (ABC). Then, a correction value (+1, -1) shown in Fig. (B) is added (subtracted) to the three bits (DEF) at the rough side, thereby correcting the three bits (DEF). The bit shift is eliminated through bit operations along with the correction.
