Title: Bottom valve for tank lorry
Inventor: SUGANO TOKIO
IPC: B65D88/12
Filed: 1995-06-21
Abstract: PURPOSE: To improve sealing ability between the outer cylinder body of a valve element and an upper valve casing and to prevent the occurrence of damage and a defect by a method wherein a spacer formed of a material, such as Teflon, being rigid and low in a friction factor, is fitted internally of the inner surface of an upper valve with and over which the outer cylinder part of the valve element is brought into pressure contact and slide through the medium of a packing and a wear ring. CONSTITUTION: The diameter and the sectional area of a spacer S, formed of a material, such as Teflon, being rigid and low in a friction factor, on the upper valve casing 2 side of which an oil chamber 30 consists are set to values remarkably higher than the diameters and the sectional areas of a valve seat 9 and a valve hole 8 on the lower valve casing 1 side. A downward press force by oil fed with a pressure and flowing fully in the oil chamber 30 through the through-hole 29 of the lower end part 15 of a valve element 3 is increased to a value eminently higher than an upward pressure force by oil in the vicinity of the valve seat 9 and the valve hole 8. This constitution strongly presses down the valve element 3 and brings the lower end part 15 of the valve element 3 into powerful pressure contact with the valve seat 9 of the lower valve casing 1 through a packing 28, reliably maintains closing of the bottom valve B of other tank chamber 20 than an object to be loaded and reliably prevents inflow of oil through the bottom valve B.

Title: Unit and method for operation, and recording medium where operation program is stored

IPC: G06F17/16
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To actualize a method for easily calculating various numerals (displacement, speed, and acceleration) regarding the motion of a plane mechanism. SOLUTION: When a triangle is regarded as a figure formed of three vectors in total, i.e., two vectors generally defined as quantities having angles and lengths and a vector produced by the sum of them, and called as a vector triangle, any complicated plane mechanism can be represented generally as a series of connected vector triangles, so the plane mechanism can be replaced with a succession of proper vector triangles and various numerals regarding the motion of the plane mechanism can be calculated. By this method, the unknowns of displacement (angle and length) of individual sides of vector triangles in arbitrary shapes and their variation speeds and variation acceleration can be calculated only by giving known numerals when the number of unknowns of each vector triangle is <=2. Further, the names characteristic of various numerals of a vector triangle which is calculated first and character strings obtained by performing some arithmetic process for them can be replaced with concrete numerals and supplied to a vector triangle which is calculated later, so when various numerals of the former vector triangle varies, the variation can be reflected later.

IPC: H01L21/68
Filed: 1990-07-06
Abstract: PURPOSE:To accurately detect the setting attitude of a boat, by measuring the distance between the boat and ultrasonic sensors when the boat is relatively moved in the direction vertical to a wafer surface, and detecting the boat setting attitude. CONSTITUTION:An elevating motor 31 is rotated in the ascending direction of a boat 2 via a motor control part 13 and a motor driving part 15. As the motor 2 ascends, the signal from a rotary encoder 9 is sequentially inputted in a boat attitude detection part 16. The signals from ultrasonic wave sensors 10, 11 also are inputted in the boat attitude detection part 16. At every time when a specified number of counts is obtained from the rotary encoder 9, the boat attitude detection part 16 takes in the signals from the ultrasonic sensors 10, 11. As the result of this operation, axial center positions of the post 4 along the whole length of the post 4 can be obtained for every specified interval by calculation. As the result of the detection of axial center positions of the post along the whole length of the post 4, the setting attitude of the post 4, i.e., the boat 2 can be obtained by calculation.
