Patent JP-H0684737-A (JP)
Title: Clean air device
Inventor: TANAHASHI TAKASHI
IPC: H01L21/02
Filed: 1991-07-11
Abstract: PURPOSE:To suppress the penetration of dust, etc., into a device from a clean room by generating a positive pressure in the device. CONSTITUTION:A blowing fan 4 makes air from an air intake 2 to blow to the inside of a device and an exhaust fan 24 discharges the air to the outside from the device. By making the intake of the air larger than the discharge of the air, a positive pressure is generated in a carrying-in and carrying-out section 10. In addition, the penetration of dust into the device from a clean room is suppressed by installing a sealing wall and sealing the section 10 only when carriers are carried in or carried out from the section 10 by using an attitude changing mechanism 15.

Title: Structure of injection valve and method for assembling same
Inventor: KITABAYASHI SEIICHI
IPC: B65D83/14
Filed: 1991-05-07
Abstract: PURPOSE:To enable an injection valve to be assembled speedily and free of any trouble in usage by fitting the valve housing in a cylindrical pit in a mountain cap tightly and in a manner of fastening it. CONSTITUTION:Into a cylindrical pit formed in the middle of the bowl-shaped bottom 5 of a mountain cap 1 held with its peripheral border down, a valve housing 3 is pushed tightly with a radially enlarged part 4 of it down. The outer diameter of this radially enlarged part 4 is slightly larger than the inside diameter of the cylindrical pit so that the outer surfaces of the radially enlarged part 4 and the inner surface of the cylindrical pit fit together tightly and do not separate easily. Furthermore, to create a fastening between the base end of the cylindrical pit of the mountain cap 1 and the end of the radially enlarged part 4 fitted therein of the valve housing 3, the mountain cap 1 is in part given plastic deformation from the outer side by the use of a pushing tool, striking tool, or the like so that the valve housing 3 is stopped from falling out of the mountain cap 1.

IPC: F04D29/44
Filed: 1989-07-28
Abstract: PURPOSE:To restrain the liner of a casing from being deformed so as to enhance a discharge performance even if an excessive external force is exerted on a suction flange by forming the tip end of a cylindrical suction nozzle, which extends toward the suction port of a casing cell, in the mouth of an impeller. CONSTITUTION:A cylindrical suction nozzle 20 extending toward an impeller 5 is integrally formed at the circumferential edge of the suction port 11 of a suction flange 10. The tip end 20a of the nozzle 20 is loosely inserted at the circumferential edge thereof into the mouth 5a of the impeller 5, and a ring-type deflector 21 having a substantially L-shaped cross-section is secured at the peripheral portion to extend in a circumferential direction. An external force exerted on the suction flange 10 is transmitted to a stationary flange 2 through the flange support 1c of a casing cell 1, and is not transmitted directly to the suction nozzle 20. Accordingly, even if the suction flange 10 is deformed by the external force, the suction nozzle 20 cannot be deformed, thereby securely preventing the tip end 20a of the suction nozzle 20 from being brought into contact with the mouth 5a of the impeller 5.

Title: Driving device for current collector
Inventor: SASAKI SHIN
IPC: B60L5/32
Filed: 1981-12-09
Abstract: PURPOSE:To prevent the damage on an overhead line and at the contact part of a pantograph due to an arc by a method wherein, when the pressure of compressed air with which the pantograph is driven drope the compressed air is discharged into the air and, at the same time, a circuit breaker is released. CONSTITUTION:The pantograph 1 is elected by supplying compressed air to a driving part 2 through an electromagnetic valve 4, and when the pantograph is not in use, the compressed air is bled and it is lowered by its own weight. At this time, a pressure detector 7 having an electric contact point 7A is connected to a feeding pipe 6, and when air pressure drops below the prescribed value, the driving coil 4A of an electromagnetic valve 4 is demagnetized by giving an OFF position to the contact point 7A. The residual air is discharged into the atmosphere by cutting off the supply of compressed air and at the same time, the circuit breaker of the main current-collecting circuit is operated by demagnetizing a relay 9. Accordingly, the pantograph 1 can be lowered without fail in case of an abnormal condition and, at the same time, the generation of arc can also be prevented, thereby enabling to prevent the damage on the overhead-line and the contact part of the pantograph.

Title: Braking device
Inventor: MATSUNAGA KUNIHIRO
IPC: B60T8/26
Filed: 1990-07-25
Abstract: PURPOSE:To stabilize controllability at the time of braking by installing a hydraulic control valve, where valve opening pressure is varied according to force being added to a rod in the longitudinal direction, in the point midway in a pipeline connecting it to a brake installed in a wheel at the opposite side to another wheel connected with the rod provided with a brake fluid pressure source and the hydraulic control valve. CONSTITUTION:Large braking force is produced in a front wheel 1 at the left on a large surface of a road surface mu, and a front wheel 2 at the right on a small surface of the road surface mu is locked at the initial stage of braking and there is produced small braking force. Since the braking force of the front wheel 2 at the right is little, small force is added to a tension rod 4, connecting the front wheel 2 to a car body, in the longitudinal direction and thereby valve closing pressure of a hydraulic control valve 17 is set to be small. Accordingly, brake fluid pressure being fed to a brake 9 of the front wheel 1 at the left at the opposite side comes to be cut at a low valve in consequence, thus braking force is held down. In general, since the braking force of the front wheel 1 at the left, where large braking force is produced by the large road surface mu, is held down by the hydraulic control valve 17, a braking difference between these symmetrical wheels 1 and 2 becomes lessened, so the behavior of a vehicle is made gentle enough.

Title: Rail support apparatus for rail vehicle
Inventor: HERUMAN ORUTOBUAIN
IPC: E01B9/54
Filed: 1983-10-24
Abstract: A mount for a railroad rail having an inner side turned toward another such rail and an outer side turned away from the other rail has a one-piece base supported on the ground under the one rail and formed with an upwardly open recess having inner and outer base flanks respectively generally under and parallel to the inner and outer sides, the outer base flank being formed as an inwardly overhanging ridge. An insert attached to the rail and received in the recess has respective inner and outer insert edges, the former of which is overhung by the ridge. An elastomeric body lies between the inner flank and inner edge and supports the insert in the base. Due to the overhang of the base edge, it is possible to make the base in one piece at least outward from a location underneath the rail. Thus there is no need to make the base from two parts split along a horizontal plane and requiring tedious assembly in the field.
