Title: Method and device for inspecting leakage of container utilizing differential-pressure change rate
Inventor: MURAKAMI KIMIHIDE
IPC: G01M3/26
Filed: 1998-11-02
Abstract: PROBLEM TO BE SOLVED: To make quickly measurable the leakage of an inspection container by measuring the change rate of the differential-pressure data of a reference container and a container under inspection immediately after a transient response period and comparing the change rate with a immediately after a transient response period and comparing the change rate with a reference value. SOLUTION: Compressed air is introduced to a reference container 1 and a container under inspection 2. By a pressurized line 4, connection to a pressurized pipe 3 is made, a solenoid valve 6 with a pressurized line is provided, and the pressurized air is supplied from an air source 7. A differential pressure gauge 8 is connected so that a pressure at both the sides of a solenoid valve 5 with the pressurized pipe is measured, and the output of the differential pressure gauge 8 is connected to a judging device 10 consisting of a computer. A manometer 9 is mounted to the container under inspection 2. When the solenoid valve 5 with the pressurized pipe is open, the pressure of the reference and inspection containers 1 and 2 is measured. On the other hand, when the solenoid valve 5 is closed, the pressure of the container under inspection 2 is measured.  Then, the change rate of the differential pressure of a specific period after transient response period passes is obtained. The change rate corresponds to a leakage area, thus comparing the change rate with a reference value, and hence detecting the presence or absence of the leakage area. For judging the presence or absence of the leakage, the inclination of the differential data of the container is measured in advance, and the leakage is judged to be allowable when the inclination is equal to or less than a preset value.

Title: Oil pressure control device for continuously variable transmission
Inventor: SATO YOSHIJI
IPC: F16H9/00
Filed: 1989-11-30
Abstract: PURPOSE:To smooth an oil pressure as a necessary oil amount is ensured by connecting an orifice and a variable orifice in juxtaposition with each other to an oil passage through which oil is fed to and discharged from a primary cylinder by exerting a duty pressure on a variable speed control valve. CONSTITUTION:A shift speed control valve 50 is alternately operated between an oil feed position and an oil discharge position by means of the duty pressure of a solenoid valve 35 for controlling a shift controlled by a control unit 60. Through repetition of the feed and discharge of oil to and from a primary cylinder 9 of a continuously variable transmission 4, a shift is controlled togetherwith a primary pressure. In this case, pulsation of the primary pressure is absorbed by an orifice 61 of an oil passage 23. A variable orifice device 70 bypassing the orifice 61 is switched by means of a pressure difference between the front and the rear of the orifice, and a necessary oil amount is fed and discharged with excellent response. This constitution prevents pulsation of the primary pressure and the increase of a torque amount without damaging response, and reduces the generation of vibration noise.

Title: Detecting device for liquid impartment abnormality
Inventor: AKASAKI KUNIO
IPC: B05C21/00
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To detect a liquid impartment abnormality on line to minimize the assurance of defective finished yarn by sensing the change of receiving quantity caused by traveling yarn having a liquid adhered thereto between a transmitting part and a receiving part. SOLUTION: A high frequency electromagnetic wave transmitted from a transmitting part constituting a sensor part 1 by the instruction (high frequency electromagnetic wave transmission instruction a) from a control part 2 is received by the receiving part of the sensor part 1. Yarn is traveled during this, and when a liquid adhered part is passed, the electromagnetic wave is absorbed by the liquid and attenuated. This change of intensity of the electromagnetic wave (high frequency electromagnetic wave receipt signal b) is recognized in the control part 2 to discriminate the presence or absence of liquid adhesion. When the frequency of liquid adhesion is differed from a prescribed frequency, a signal alarming an abnormality (cutter differential signal c) is transmitted from the control part 2, a cutter 3 is operated to cut the traveling yarn, and the working is interrupted.
