Title: Snow removing device for roof
Inventor: HASHIMOTO RYOJI
IPC: E04H9/16
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To efficiently remove snow by driving with a drive member for controlling a movable member vertically reciprocated along the upper face of an inclined roof by a control member. SOLUTION: A movable member 1 of substantially the same length as the ridge of an inclined roof 2 can be vertically reciprocated along the upper face of an inclined roof 2 through guide rails 5, 6 vertically attached to the center part and/or both the side parts of the inclined roof 2. A cable 14 is wound on rotation members 10-13 attached to the four-corner part of the inclined roof 2 in a tight state in substantially eight-shape, and the movable member 1 is driven by a drive mechanism 9 controlled by a sensor. When the rotation member 10 is rotated by the motor 9 of the drive mechanism 15 clockwise, the cable 14 wound in the substantially eight-shape is moved so as to illustrate the substantially eight-shape while the tight state is held, and both the ends of the movable member 1 is pulled downward.  The movable member 1 is lowered along the guide rails 5, 6 while cutting the side of the snow layer of the upper face of the inclined roof 2, and the snow layer upward of a cross section falls by self weight. A simple device and small drive force enable snow removing of mechanically good efficiency.

IPC: F15B11/22
Filed: 1999-11-09
Abstract: PROBLEM TO BE SOLVED: To provide a device for diagnosing failure of a hydraulic cylinder capable of easily diagnosing a failure of plural hydraulic cylinders connected in parallel with each other through a hydraulic circuit. SOLUTION: A pair of hydraulic cylinders 7, 8 are connected in parallel with each other through hydraulic circuits 11, 12, and a direction indicating flow meter 17 for detecting the flowing direction of the hydraulic oil is provided in the hydraulic circuit 11 of the dead load holding side of the hydraulic cylinder 7. With this structure, when an internal leak is generated in the hydraulic cylinder 7, for example, since the operating liquid flows from the hydraulic circuit 11 of the dead load holding side to the hydraulic circuit 12 through the inside of the hydraulic cylinder 7 when a control valve 13 is positioned at a neutral position, flowing direction of the hydraulic oil is detected by a direction indicating flow meter 17 so as to confirm the generation of the internal leak of the hydraulic cylinder 7.  Since the hydraulic oil flows out of the hydraulic cylinder 7 to the hydraulic circuit 11 of the head load holding side when the internal leak is generated in the hydraulic cylinder 8, flowing direction of the hydraulic oil is detected by the direction indicating flow meter 17 so as to confirm the generation of the internal leak of the hydraulic cylinder 8.

Title: Mpeg picture reproduction device and mpeg picture reproducing method
Inventor: AOKI MASAYUKI
IPC: H04N19/85
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To reproduce a picture at high speed without deteriorating the quality of the reproduced picture by decoding only I and P pictures, in high speed reproduction in a device in which a dynamic picture is compressed by the MPEG system, and picture coding data constituted of I, B, P pictures are decoded and the data are outputted for each frame. SOLUTION: In high speed reproduction, picture code data separated from a code input signal received by a PES decoder 2 are given to a B picture skip circuit 2. Since a B picture header detection circuit 11 activates a B picture skip signal, only while a B picture code is received, the B picture skip circuit 12 skips the B picture code and provides an output of only I, P picture codes. Then an M detection circuit 10 detects the interval of anchor frames of the image code data of the code input signal, and a display control section outputs image data of I, P pictures by a display method, depending on the anchor frame interval and high reproduction speed.

Abstract: PURPOSE:To facilitate mounting of a protection plate for a columnar substance by a method wherein a peripheral notch is formed in the outer periphery of a cylinder formed of fiber- reinforced resin, the inside diameter, the modulus of elasticity, and the fiber-reinforced material content of the cylinder are specified, and the notch is elastically fitted in the columnar substance. CONSTITUTION:An inside diameter D1 of a protection plate 1 formed of fiber-reinforced resin is decreased to a value lower than the outside diameter of a columnar substance to be installed and an inner periphery 7 is set to a value higher than a half the outer periphery of the columnar substance. Opening ends 15 of the plate 1 are forcibly spread therebetween and fitted in the columnar substance and the columnar substance is grasped through elasticity of a plate 1 itself. The modulus of elasticity of 2 fiber-reinforced resin is set to 700-3000kgf/ mm<2> and a fiber-reinforced material content in fiber-reinforced resin is set to 30 60wt.%. An irregular surface, such as a stripe-form state, is formed in the outer peripheral surface of the plate l to prevent paper from being mounted. Further, the inner periphery of the plate 1 is increased to a value higher than the outer periphery of the columnar substance and set to a value 3/4 or less the outer periphery of the columnar substance. This constitution causes reduction of the weight of the protection plate, formation of the protection plate in a compact state, safe and easy mounting of it without using a bolt, and improvement of corrosion resistance and paper-mounting preventiveness.

Abstract: PURPOSE:To prevent trouble from arising due to deformation or crushing of a pipe-shaped inside sheath during manufacturing processes by installing a pressure-reducing molding device between an extrusion molding device and a cooling molding device so as to reduce the pressure of the inside sheath outwards, for swelling the sheath. CONSTITUTION:Plastic material is extruded around the outer periphery of an inside conductor 1, and then a helical rib 22 and a pipe-shaped inside sheath 21 located around the outer periphery of the rib 22 are extruded and molded simultaneously, and then cooled and hardened to form an insulator. Then a pressure-reducing molding device 11 is installed between an extrusion molding device 6 and a cooling molding device 7 and the pressure of the pipe-shaped inside sheath 21 is reduced outwards by the device 11 so that the sheath is swelled. The pressure inside the inside sheath 21 may therefore be converted to atmospheric; pressure; in the case of taking up an insulator 2 onto a take-up drum 10, cutting of the insulator 2 will thus not cause such a trouble that the pressure inside the insulator 2 drops abruptly to cause the inside sheath 21 to be crushed between the extrusion molding device 6 and the cooling molding device 7.

Abstract: PURPOSE:To prevent generation of air bubbles and remaining of a polyvinyl alcohol (PVA) layer to serve as an oxygen barrier film on a resist layer and to avert degradation in resolution by coating an aq. PVA soln. on the resist layer for X-ray exposure, then drying the coating, thereby forming the above- mentioned PVA layer. CONSTITUTION:CMS (chloromethylated polystyrene) which is a negative type resist is spin-coated on a substrate 22 consisting of a silicon wafer and is then prebaked. The aq. PVA soln. is then spin-coated on the resist layer 23 consisting of the CMS and the coating is heated after coating, by which the PVA layer 24 to serve as the oxygen barrier film is formed. The X-rays of the prescribed pattern formed by a mask 15 are projected through this PVA layer 24 to the resist layer 23. The PVA layer 24 is then dissolved away by pouring pure water on the substrate 22 surface. The CMS resist layer 23 of the part subjected to the X-ray irradiation remains when the CMS resist layer 23 is thereafter developed by using the prescribed developing soln. The resist pattern having the high resolution in X-ray exposing is thereby formed.
