Title: Powder molding machine
Inventor: TOMOTO AKIHIRO
IPC: B30B11/18
Filed: 1997-12-04
Abstract: PROBLEM TO BE SOLVED: To ensure the smooth and uniform feeding in of a force feeding in type powder molding machine by a screw feeder 1 with a deaeration function. SOLUTION: A screw feeder 1 is provided with a biaxial roll compression molding machine 2 in continuation with this feeder. The screw feeder 1 is a self-cleaning type having biaxial screws 4 and is deaerated by the air suction from a deaeration chamber 25. The powder is contracted and is made hardly transportable by the deaeration but if the machine is the self-cleaning type, the powder is uniformly fed into the roll compression section without clogging in the screw feeder. In addition, the inside of a seal casing 6 is deaerated as well, by which the air pressure increase in the seal casing 6 is suppressed and the pressure difference between the inside of the casing 6 and the atm. air is diminished and the leakage of the powder from between the rolls 21, 21' and the casing 6 is suppressed.

Title: Detecting method for position of moving body at inside of pipe
Inventor: YOSHIDA OTOO
IPC: G01B7/00
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To obtain a detecting method in which the position of a moving body can be detected by a method wherein a magnetic signal is transmitted at a low frequency from the moving body, a magnetic flux is leaked to the outside of a pipe and the intensity of the leaked magnetic flux is detected from the outside of the pipe. SOLUTION: Flux gate sensors which are installed respectively at a magnetism detector B1 and a magnetism detector B2 are supported so as to be freely rotatable integrally around their up-and-down axial center by keeping a prescribed set interval in the up-and-down direction by putting their sensitity direction in order. After an inside-pipe running vehicle A is run by a prescribed distance at the inside of a gas pipe 8, it is stopped. An oscillation coil 1 is electrified, and a magnetic signal is transmitted at a low frequency of 20 Hz. While a carriage D on the ground is being moved, the intensity of a leakage flux from pipe P is detected by the respective detectors B1, B2, and their detection outputs are displayed on respective display devices.  The detection outputs by the detectors B1, B2 and the interval between the flux gate sensors are used, and a depth up to the running vehicle A from the detectors B1, B2 is found. Consequently when the position of the inside-pipe running vehicle A is detected, the burial position of the pipe P can be known.

Title: Hydraulic damper
Inventor: NAKANISHI HIROSHI
IPC: F16F9/50
Filed: 1987-12-28
Abstract: PURPOSE:To automatically adjust generated damping force by using a damping valve having a two-degree freedom configuration, which is set so as to resonate in a specific range of a system to be controlled, and by increasing the opening degree of the valve in association with the resonance of the valve. CONSTITUTION:A twin tube type hydraulic damper is composed of a body 1 and a damping valve section 2. When the vibration frequency of a system to be controlled is in an intermediate range between a primary resonant point and a secondary resonant point, ports 17, 18 are opened to a large degree so as to decrease generated damping force. When the vibration frequency of the system to be controlled comes into a high range, a large damping force is produced since the ports 17, 18 are closed. Thus, it is possible to automatically adjust and change generated damping force in response to the vibration frequency.

Abstract: PROBLEM TO BE SOLVED: To manufacture a windshield wiper simply and inexpensively by connecting wiper support parts supported rotatably on a wiper arm and a wiper support mutually in the form of a rigid constituent unit and moving the wiper arm elastically in the axial direction in parallel with the radial direction. SOLUTION: A wiper arm 2 of a windshield wiper 1 is constituted in such a way that a U-shaped hook 4 and an end on the opposite side are inserted into a groove 7 of a wiper support part 5 and are fixed by a set screw 9. Since the wiper support part 5 has a wiper support shaft 8 coaxial with a wiper axis 6, the wiper arm 2 protrudes laterally from the wiper support part 5 and protrudes in the radial direction for the wiper axis 6. The wiper support shaft 8 is rotatably held in a bush of a wiper support and can oscillate in a reciprocating manner by a drive device. The wiper arm 2 has a wave shape 3 in a scope continuous with the wiper support part 5. This scope of the wiper arm 2 is likely to bend elastically due to the wave shape 3.
