Title: Fm tuning detection circuit
Inventor: IENAKA MASANORI
IPC: H03J3/12
Filed: 1979-01-29
Abstract: PURPOSE: To make it possible to detect an accurate tuning point by providing a series diode to an output circuit and then by generating a V-shaped conversion output by a transistor which changes the forward voltage of this diode into a bias voltage.  
     CONSTITUTION: A quadrature detection circuit consists of transistors TrQ 1 ∼TrQ 6  and phase shifting circuit 1. As a result, FM detection output currents mutually out of phase appear at respective collectors of TrQ 3  and TrQ 5 , and TrQ 4  and TrQ 6 , and push-out currents mutually out of phase at collectors of TrQ 7  and TrQ 8 . Then, an absorption current output equivalent to this current output can be obtained at the collector of TrQ 9 . Then, when bias voltage VB is applied to the connection halfway point of diodes D 4  and D 5  provided between TrQ 8  and TrQ 9 , resistance R 2  generates an S-shaped detection output. This voltage VB is applied to emitters of TrQ 10  and TrQ 11  and the collector absorption current of TrQ 10  is converted into a push- out current through TrQ 12 . This push-out current and that of TrQ 11  are flowed through resistance R 2  to obtain S-shaped characteristics.

Abstract: PURPOSE:To stabilize and improve the cooling performance of the heat exchanger by providing liquid refrigerant distributing chambers at the top of heat transmission pipes so as to guide the liquid refrigerant contained in the refrigerant that enters as a mixture of two phases uniformly across the entire heat transmission pipes and to maintain a stabilized liquid level so that the liquid refrigerant may uniformly flow down. CONSTITUTION:The mixed phase refrigerant of refrigerant vapor 5a and liquid refrigerant 6a that has exited out of expansion valves etc. hits the surface of the inner pipe 8 from the refrigerant feed pipe 7 at a substantial speed to be directed in the circumferential direction of the distribution chamber 10b, and the refrigerant vapor 5b enters into the distribution chamber 10a via the notch 9a at the top of the inner pipe 8, and the liquid refrigerant 6b via the notch 9b in the lower position. The liquid refrigerant 6c receives heat from the fluid18 in the heat transmission pipe 2 as it flows down from the port 14 along the surface of the heat transmission pipe 2, forming the liquid film 16. It thereafter becomes vapor 5d which is released outside the heat exchanger from the refrigerant vapor outlet 17. Since the liquid level of the liquid refrigerant 6c is maintained at a constant level by the hight of the liquid refrigerant overflor pipe 11, and any liquid refrigerant exceeding the hight is drained through the overflow pipe, it can be directed to the lower part of the heat transmission pipes without causing mist-up.

Title: Method of detecting abnormality of steam power plant
Inventor: OKADA MIKIO
IPC: F01D21/00
Filed: 1981-01-26
Abstract: PURPOSE:To early detect the abnormality of an extraction check valve for a steam turbine, by finding out the temperature between the extraction check  valve and the turbine and comparing the temperature with normal data stored  in a computer. CONSTITUTION:Receiving a turbine stop signal 16, a detector 13 finds out the temperature of extraction. Temperature data for a prescribed time are obtained to determine the temperature-drop characteristic, which is compared with a reference temperature-drop characteristic previously stored in a computer 14. When an extraction valve 9 is normal, the ratio between passed time and the drop DELTATa in the temperature of extraction during the stoppage of a turbine is approximate to that between passed time and the reference temperature drop DELTATb. When the extraction check valve 9 is abnormal, the ratio between passed time and the temperature drop DELTATa' is greatly different from that between passed time and the reference temperature drop DELTATb. Therefore, the abnormality of the valve 9 can be detected by comparison.

Inventor: NISHI SEIJI
IPC: C23C14/34
Filed: 1999-01-18
Abstract: PROBLEM TO BE SOLVED: To obtain an alloy target material in which the generation of sticking caused by inclusions in the target material called as particles is hard to occur by controlling the all maximum lengths of inclusions present therein to the length equal to or below the specified one. SOLUTION: A cobalt alloy ingot by a vacuum induction melting method is remelted by a vacuum arc melting method. This ingot is forged, rolled and thereafter machined to produce a cobalt alloy target material. By controlling the conditions of the vacuum induction melting, the conditions of the vacuum arc melting method or the like, the cobalt alloy target material in which the all maximum lengths of inclusions present therein is <=20 μm can be obtd. By this cobalt alloy target material, the generation of adhesion caused by inclusions in the target material called as particles at the time of sputtering is made rare. As the inclusions include oxides, nitrides or the like, they influence on the generation of particles, and, in the case the all maximum lengths thereof is <=20 μm, the number of particles remarkably decreases.
