Title: Axial flow fan
Inventor: INAZUMI HIDEYOSHI
IPC: F04D25/08
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To reduce the noise caused by the air current flowing on the negative pressure surface side of a blade part by forming a rough face from the counter rotating direction side of the negative pressure surface of the blade part over an outer peripheral surface, and widening the rough face toward the outer peripheral side. SOLUTION: A plurality of blade parts 3 are radially formed from an outer periphery of a boss part 1. A rough face 4 is formed on the negative pressure surface side of the blade part 3 from a center of a side edge in the counter rotating direction with respect to the rotating direction, toward an outer peripheral edge in a state that it is gradually widened toward the outer peripheral side. The rough face 4 has a number of irregularities like ground glass, sand paper or the like. By forming the rough face 4 over the outer peripheral side of the blade part 3 where a speed of the air current is the fastest and the separation is easily generated, that is, by surely disturbing the air current of high speed by the rough face 4, the noise following the separation of the air current flowing on the outer peripheral side of the highest capacity, can be surely reduced.

Title: Charging display device for high voltage line
Inventor: FUKUDA JUNJI
IPC: H02G1/02
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To discriminate presence of charging at a remote place with high accuracy by disposing a voltage detecting part and an electrode part coming into contact with a charging part connected to the voltage detecting part, and providing a data transmitting means for transmitting a charging condition to an insulation rod in an electrically insulating condition. SOLUTION: This charging display device 10 is provided with a voltage detecting part 12 for neon lamp or the like which turns on at the time of charging, and a protruding electrode part 13 fitted on the end of an insulation rod 11 whose insulating quality is excellent. A data transmitting means 14 disposed with an insulating condition kept is mounted between the end and the base part of the insulation rod 11 to transmit data to a display device 15 through a signal cable 15a. The voltage detecting part 12 operates on no-power supply with partial voltage of ground voltage distributed by impedance through an electric insulator between the electrode part 13 and a clamping part or a grounding part, thus emitting light. When the electrode part 13 is brought into contact with the high voltage line, light is emitted by a potential difference with partial voltage.  It is thus possible to discriminate presence of charging at a remote place with high accuracy.

Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of conversion to a one-way flow through reduction of incurring of a flow rate loss by providing a flow control device to form a flow constantly in one way at an output circuit by controlling a flow generated owing to vibration of a liquid piston. SOLUTION: A flow generated due to vibration of the liquid piston of a liquid piston engine 11 flows through a first one-way counterflow valve 41, disposed at a first closed circuit 21, to an output circuit 3 and flows from an output circuit through a third one-way valve 43, disposed at a first closed circuit 21, to one engine 12. A flow generated due to vibration of a liquid piston of the other liquid piston engine 12 flows through a second one-way valve 42, disposed at a second closed circuit 22, to an output circuit 3 and flows from the output circuit 3 through a fourth one-way valve 44, disposed at the second circuit 22, to the other engine 11.

Title: Paper feeder for office equipment
Inventor: MATSUURA YASUO
IPC: B65G1/02
Filed: 1989-11-28
Abstract: PURPOSE:To prevent a plurality of sheets of paper form from being placed in a paper separating part between a paper feed roller and a separating surface by forming friction surface of large coefficient of friction in a part of a paper guide opposed to the paper feed roller of a paper form guide. CONSTITUTION:In the case of inserting paper forms 16, laminated in a large number of sheets, along the guide surface 12 of a paper guide 13, since a point end of the paper form 16 is brought into contact with a separating surface 11 with an obtuse angle formed for the guide surface 12, the paper form 16, even when its press-in force is strongly given, is stopped in that position. That is, the separating surface 11 acts as a stopper for the press-in of the paper form 16. In the paper form 16 thus pressed in, since the paper form in the uppermost surface is brought into contact with the peripheral surface of a paper feed roller 15, when it is started to rotate, the paper form is fed out along a direction of rotation of the roller 15. Now even when two sheets of the paper forms 16 are placed between the paper feed roller 15 and a friction surface 18, the paper form 16, brought into contact with the friction surface 18, is prevented from being fed out because friction force between the paper form 16 and the friction surface 18 is larger than friction force between the paper forms.

Title: Preservation treatment method of wood and device
Inventor: OKUJIMA KEIJI
IPC: B27K5/00
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To realize the heating of not only the ambient but also the interior of woods up to enough temperature at the heating of the woods for vaporizing the solvent in a preservative-containing solution infiltrated in the woods with the impregnating tank by a method wherein the woods in the impregnating tank are directly high-frequency heated. SOLUTION: In this wood preservation treatment device 1, a high-frequency heating device 31 is provided. The output of the high-frequency heating device 31 is supplied through lead wires housed in a piping 33 to electrode plates in the impregnating tank 2 so as to directly high-frequency heat the interior of woods 3. In addition, a cooling pipe 37 is piped on the bottom part of the impregnating tank 2. Since being heavier than the air, a solvent vapour tends to gather at the bottom part of the impregnating tank 2, resulting in allowing to liquefy the major part of the solvent vapour in the impregnating tank with the cooling pipe 37 on the bottom part of the impregnating tank 2. Thus, since the solvent vapour is directly cooled at the bottom part of the impregnating tank 2, its liquefaction efficiency is good.  This device has a remarkably high efficiency as compared with that of the conventional device, in which a recovering piping system is employed.

Title: Rotary control valve for hydraulic power steering gear
Inventor: SASAKI HIROTO
IPC: B62D6/02
Filed: 1992-10-23
Abstract: PURPOSE:To finely control hydraulic pressure which acts on a hydraulic actuator by providing a drive means for axially driving a bearing which supports either a first or a second valve. CONSTITUTION:The centrifugal whirling of input and output shafts 2, 3 is absorbed by the radial displacement of a cylinder member 26 inserted in a housing 7 via an elastic sealing member 25. Because a first valve 31 is axially movably inserted into the cylinder member 26, the axial movement of the first valve 31 proportional to vehicle speed is not blocked by the sealing member 25, so an optimum steering characteristic corresponding to vehicle speed can be obtained. The first valve 31 is supported by a bearing 81 and the axial drive of the bearing 81 allows the first 31 and second 32 valves to smoothly rotate relative to each other, allowing fine control of hydraulic pressure acting on a hydraulic cylinder 20.
