Title: Emergency shut-down valve
Inventor: YONEYAMA TAKASHI
IPC: F16K17/36
Filed: 1993-09-29
Abstract: PURPOSE:To provide an emergency shut-down valve which can mitigate a water hammer phenomenon even if the valve is emergently shut down by fitting an actuator of which motion and the valve stem are constituted so as to form a scalene right angled triangle. CONSTITUTION:A fork lever 11 is provided with a slotted hole 8 in the lengthwise direction, and a pin 10 planted on the side of a piston rod 9 is engaged with the slotted hole 8. An actuator 4 is constituted of a piston 6 and a cylinder 7, and a valve closing port 13 is connected to the upper stream side of the cylinder 7, and a valve opening port 12 is connected to the lower stream side. The position B of the pin 10 at full closing of the valve, the position C' of the pin 10 at full opening of the valve, and the center A of a valve stem 5 form an triangle. An angle acute angleBC'A can be expressed as 45+(alpha), but for example in case of (alpha)=30, at first the valve is quickly closed, but at approaching the full closing condition it is slowly closed. As a result, water hammer phenomenon is mitigated.

Title: Method for self-diagnosis of sensor signal processing circuit
Inventor: TABATA TAKASHI
IPC: G01P21/00
Filed: 1991-09-24
Abstract: PURPOSE:To enable removal of a cause of erroneous decision by a method wherein an output value of a processing circuit at the time of self-diagnosis is monitored at two different time points and it is detected whether a difference between output values monitored at the different time points is within prescribed limits or not. CONSTITUTION:The sensitivity of a sensor output VOUT is determined on the basis of a G input at a point A. Based on the G input at the point A and the G input at a point B which are monitored, subsequently, a difference between them, that is, whether the value of A-B=DELTAV is within prescribed limits or not, is checked. When the result is YES, checking of the sensor output is ended. When it is NO, a filter fault flag is set ON and it is detected that a filter circuit 3 is not normal. In conclusion, whether the inclination of the sensor output VOUT (the time constant of the circuit 3) is normal or not is determined on the basis of the value of the potential difference DELTAV between the point A and the point B, and thereby it can be detected whether the function of the circuit 3 deteriorates or not.

Title: Auger electron spectroscope
Inventor: ITO YOSHIAKI
IPC: H01J37/305
Filed: 1987-09-29
Abstract: PURPOSE:To make an accurate depth direction analysis executable by irradiating an electron beam and an ion beam to a sample alternately. CONSTITUTION:Ion beam irradiation takes place as long as 30 minutes, by way of example. During irradiation for 30 minutes of this ion beam, no irradiation of an electron beam 3 takes place there. That is to say, during this interval, an electron beam deflecting coil 2 is operated by a command out of a control part 5, the electron beam 3 is deflected, whereby it is not reached to a sample 9. After an elapse of 30 minutes, feed of a negative electric field is stopped to a drawer electrode of an ion gun 7 by a command out of this control part 5, whereby emission of an argon ion beam out of this ion gun 7 is stopped as well. Next, operation of the deflecting coil 2 is stopped by a command out of the control part 5 so that the electron beam 3 goes straight without being deflected again, and it is reached to the sample 9. Sample irradiation of the electron beam 3 takes place for about two minutes long. An Auger electron is emitted from an element in the sample by irradiation of the electron beam 3. consequently, if intensity of energy in the Auger electron is inspected, the element is made analyzable.
