Title: Soundness checkup method for pile foundation
Inventor: TAKAHASHI HIROSHI
IPC: G01N33/38
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To identify sizes and positions of cracks at a low cost by a method wherein Lugeon tests are performed at fixed intervals, utilizing a bore bored to a pile from its upper end toward the lower side, and the crakcs are idnetified, based on the results of the tests. SOLUTION: A bore 3 is bored by boring to a pile, extending from the center at the upper end 2 of the pile toward its lower side. The bore 3 to be bored to the pile 1 shall be small in diameter so that it may not spoil performance (strength or the like) of the pile 1. In the case where a bore is originally provided at a pile 1, the existing bore is used as it is. Lugeon test, a test for checking permeability at a ground or the like, is performed at fixed intervals, and positions and sizes of cracks 4 are identified, based on the results of the tests. Thereby, cracks not only at the periphery of a wall of the bored hall, but also at positions piercing through dominant sections against the soundness of the pile can be identified for their sizes and positions. Distribution density of the cracks can also be found.

Title: Self-distribution valve
Inventor: JINNAI TEIJI
IPC: F16K21/00
Filed: 1978-10-25
Abstract: PURPOSE: To protect a high-pressure hose by using a self-distribution valve placed in connection with the outlet of a high-pressure pump of a high-pressure cleaning device, which turns high-pressure water into a tank when a spray nozzle in connection to the high-pressure pump stops emmision of water.  
     CONSTITUTION: A self-distribution valve is applied for a high-pressure washing device. When a high-pressure pump 16 starts operation, with a stop valve 28 of a spray nozzle 27 closed, a pressure induction chamber 2 and the internal of a nozzle high-pressure hose junction 10 become at the same pressure due to shut- off of flowing through a throttle aperture 4. Only a valve element 8 is subjected to a  pressure to open. The pressure in the pressure induction chamber 2 to drive a  pump 16 reduces up to a half approximately in comparison with a pressure put out  from the chamber. When said stop valve 28 is opened under the state, a pressure  applied to the piston 3 closes the valve element 8 to release high-pressure water.  Water is sprayed from a spray nozzle 27.

Title: Acceleration cut switch
Inventor: HIROTA HISATOSHI
IPC: B60H1/32
Filed: 1980-09-22
Abstract: PURPOSE:To ensure the smooth acceleration of a car by detecting the sudden lowering of the negative pressure in a manifold in a car conditioner at a sudden acceleration and intermitting a cooling compressor temporarily via a delay switch. CONSTITUTION:When the negative pressure in a chamber A2 is high, a negative pressure lowering detection valve A is opened, and the negative pressure is introduced into a negative pressure delay switch C from a manifold M. When the negative pressure is changed suddenly, a high negative pressure stop valve B is delayed by a throttle valve 26 in opening, and connected to the chamber A2. When the negative pressure is suddenly changed by a fixed value or more in the negative pressure delay switch C, the detection valve A is closed, and as the atmospheric pressure is introduced from the throttle valve 26, the negative pressure is gradually lowered, and a contact S is delayed in closing. Thereby, the operation of a compressor is temporarily intermitted. Besides, the high negative pressure stop valve B is used to prevent the negative pressure lowering detection valve A from the high negative pressure caused by engine braking.

Title: Device and method for granulating non-hydrophilic fine powder
Inventor: KASHIO MINORU
IPC: B01J2/14
Filed: 1984-06-27
Abstract: PURPOSE:To granulate batchwise or continuously using water as binder, by feeding water and fine powder contained in the gas generated during combustion of mineral oil, etc. to a rotary disc, kneading the mixture, and forming powdery product having the same shape. CONSTITUTION:Powdery body is fed from a feeding port 8 and granulated product formed in the inside is discharged from a discharging port 10.

A disc-type granulator provided with revolvable vanes 3 diffuses water into the air layer contained in the non-hydrophilic fine powder by the stirring effect of the vanes to form mist or sludge from the powder. Since the fine powder can be sufficiently affinitive to mist-like material or sludge in spite of its nonhydrophilicity, continuous preparation of uniform particles is possible.
