Title: Shock supporter
Inventor: CHISHIMA KAZUO
IPC: B60G13/00
Filed: 1983-02-22
Abstract: PURPOSE:To support a substance at characteristic frequency in a narrow space, by coupling the narrow space between members requiring a shock support with a cylinder as well as coupling a wide space with another cylinder and an air spring in combination, while interconnecting both cylinders through with a variable orifice. CONSTITUTION:Due to a variation of load in a substance 1 to be shock-supported by a foundation plate 2, when the volume of a working fluid 5 inside a cylinder C1 in a narrow space varies, this variation is transmitted to a cylinder C2 in a wide space via a pipe 6. And when the volume of another working fluid inside the cylinder C2 increases, an air spring 10 is compressed, and in contrast with this, when the volume decreases, the air spring 10 is extended and supported whereby supportable with the cylinder C1 even in the narrow space. What is more, in connection to pressure receiving areas of these cylinders C1 and C2, a similar effect that proper vibration in the C1 side is lowered more down than that of the C2 and elastic support takes place at a low spring constant can be obtained. A variable orifice 11 is controlled in its diameter by variations in interval pressure 13 of the air spring 10, thus a damping coefficient ratio is able to be constant all the time.

Title: Extrusion coating device
Inventor: WATANABE MASARU
IPC: B05C5/02
Filed: 1988-02-08
Abstract: PURPOSE:To enable extrusion coating of a coating liquid to a desired coated film thickness in a short period of time at the time of restarting of coating and to improve the yield of products by constituting an extruding nozzle in such a manner that the nozzle can rotate around a coating liquid supply pipe. CONSTITUTION:The extruding nozzle 3 is rotationally moved from an ordinary coating position and is parted from a base 1 and simultaneously, the extrusion of the coating liquid from the extruding nozzle 3 is stopped during continuous coating; in addition, the coating liquid is fed continuously without stagnation to the coating liquid supply pipe 6. Flocculation of magnetic particles by the stagnation of the coating liquid during the passage of the joint part of the base is thereby obviated and, therefore, the coating liquid can be coated to the prescribed film thickness in a short period of time at the time of restarting of the coating. The yield of the products is thereby greatly improved.

IPC: B66D1/44
Filed: 1995-02-15
Abstract: PURPOSE: To enable a device to perform both ordinary up/down winding operation and fine speed down winding operation without enlarging a size of the hydraulic winch device. CONSTITUTION: In a winch device formed by supplying delivery oil of a main pump 11 to an oil hydraulic motor 17 through a direction control valve 13 and through a counter balance valve 16 so as to rotate a drum 19 connected to the oil hydraulic motor 17, a charge oil path 25 is connected to a port 17a in a wind up side of the oil hydraulic motor 17 so that delivery oil of a charge pump 26 can be drawn out through a check valve 27. When a brake 20 is released, the drum 19 tends to rotate by its own suspending weight, to fine speed wind down a winch by a leak of the oil hydraulic motor 17 generated by a holding pressure in the wind up side port 17a. When a delivery amount of the change pump 26 is adjusted, a fine speed down winding speed of the winch can be controlled.

Title: Separating mechanism for paper sheet feeder
Inventor: ASAMIZU YOSHINORI
IPC: B65H3/06
Filed: 1992-01-17
Abstract: PURPOSE:To improve separating performance and feeding accuracy of paper sheets by coaxially mounting a friction roller, brought into press contact with a feed roller, through a friction clutch between a pair of separating rollers. CONSTITUTION:A pair of separating rollers 8 are mounted on a rotary shaft 8s, and a friction roller 9 brought into contact with the second feed roller 7 is mounted through a friction clutch 10 onto the intermediate of this rotary shaft 8s. When only a single sheet is fed to pass through between the second feed roller 7 and roller 9, since friction force between a paper sheet P and the friction roller 9 overcomes torque of the friction clutch 10, the friction roller 9 is rotated together with the feed roller 7, but when two sheets or more are fed to pass, since the torque of the friction clutch 10 overcomes interpaper friction force, the friction roller 9 is rotated in a direction equal to the rotary shaft 8s, that is, reversed to treat a double paper feed.
Patent JP-H02209333-A (JP)
Title: Sheet feeder
Inventor: NISHIMOTO YOSHIBUMI
IPC: B65H5/00
Filed: 1989-02-06
Abstract: PURPOSE:To achieve the promotion of low cost and thin type as well as to dispense with any complex control by using such one with a lot of air holes as an elastic body, and installing a vacuum generating means which generates negative pressure on an elastic body surface via these air holes and thereby pressing a sheet. CONSTITUTION:An elastic body 3 is connected to a grounded circuit as an electric conductor and frequency voltage is impressed on a vibrator 1 by a generator 6, thus generating a vibration in the elastic body 3. A vibrator 2 generates power with the vibration, but it is dissipated at an energy absorbing part 8, and its vibrational movement is not reflected and thereby it comes to a progressive wave. When a bending vibration of the elastic body 3 comes to the progressive wave, at an outer part of bending, it has a velocity component in the reverse direction to the forward direction of the progressive wave at all times. On the other hand, air holes 4-1-4n of the elastic body 3 are connected to a pressure generator 7 for generating negative pressure in and around it, and thereby a sheet placed on the surface is pressed to a surface of the elastic body 3. Thus, since the velocity component in the reverse direction to the progressive wave is generated on the surface of the elastic body 3, a pressure sheet is conveyed in direction of this velocity component.

Title: Torsion bar type suspension device
Inventor: NAGAYA HIROSHI
IPC: B60G17/015
Filed: 1989-02-06
Abstract: PURPOSE:To reduce the change in the posture of a vehicle according to its operating conditions for improved driving stability by controlling a liquid- operated expandable mechanism provided between an arm and a vehicle as necessary to carry out vehicle height control and spring constant control at the same time. CONSTITUTION:The liquid pressure of an expandable mechanism 54 provided between an arm 28 and a vehicle by a liquid feed/discharge device is adjusted as necessary and a torsion bar 18 is energized through the arm 28 to adjust the height of a vehicle. At the time of vehicle height adjustment, the middle portion in the torsion bar 18 has a regulated displacement by the reaction force of an accumulator 72 communicated with the expandable mechanism 54 in addition to the reaction force from the vehicle side at one end in the torsion bar 18, so that the spring constant by the torsion bar 18 increases substantially. The spring constant by the torsion bar 18 increases substantially by closing or throttling a control valve 69 regardless of vehicle height adjustment. It is thus possible to reduce the posture change in the vehicle according to its operating conditions.

     CONSTITUTION: Conductive fibers such a carbon fibers and the like are dispersedly arranged in the base hardened by inorganic binder like permanent cement and so on for constructing a heater. Since this heater is poor in the filling amount of conductive fibers, the conductive fibers are prevented from being exposed on the surface of the heater for keeping safety.

Title: Dressing device for polishing pad
Inventor: AMARI MASAHIKO
IPC: B24B53/017
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To provide a dressing device in which a polishing pad can be cleaned from a surface layer to a deep layer without leaving polishing dust. SOLUTION: A nozzle 14 to jet cleaning liquid is moved to oscillate about an axis of a pipe 16 by a motor 30, so a jet angle of the nozzle 14 to a polishing pad 50 is periodically changed. When a jet axis of the nozzle 14 is roughly perpendicular to a surface of the polishing pad 50, cleaning liquid jetted from the nozzle 14 reaches a deep layer of the polishing pad 50, so polishing chip accumulated in the polishing pad 50 is dug to float to a surface layer of the polishing pad 50. When the jet axis of the nozzle 14 is diagonal to the surface of the polishing pad 50, cleaning liquid jetted from the nozzle 14 removes polishing chip on a surface layer of the polishing pad 50.
