Title: Flame holding structure of combustor
Inventor: OTSUKA MASAYA
IPC: F23R3/18
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To improve reliability of a combustor with a higher stability of flame by a method wherein passages are provided to link the front on the upstream side of a flame holder contacting a premixed gas unburned to the rear on the downstream side of the flame holder for holding the burned gas of the premixed gas to inhibit changes in a circulation flow generated on the rear of a flame holder. SOLUTION: A plurality of passages 17 are arranged inside a flame holder 10 to link the front 15 on the upstream side of the flame holder 10 contacting a premixed gas 9 unburned to the rear 16 on the downstream side of the flame holder for holding a burned gas of the premixed gas 9. The cross section of each passage is a hole in shape and the plurality of passages on the rear 16 of the flame holder are the same in the direction of outflow. At this point, as the premixed gas 9 flows into the rear 16 of the flame holder 10 passing through the passages 17, a flow circulating in the direction the same as the direction of outflow is intensified to make the flow on the rear of the flame holder 10 asymmetrical.  This reduces the circulation flow opposite to the direction of outflow of the passages 17, thereby inhibiting changes in the circulation flow as caused by the generation of an alternating flow.

Inventor: FUKUDA JIYUNICHI
IPC: G01M3/26
Filed: 1979-08-20
Abstract: PURPOSE: To reduce the measuring error due to temperature change, by preventing the temperature rise of measured object, by providing the exhaust duct having the switching valve at the different position from the pressed air intake of measured object.  
     CONSTITUTION: In measuring the leakage of measured object 2, the pressure valves  4, 5 for passed air intake and switching valves 14, 18 provided at opposite side  of the pressed air intakes 12, 16A are opened, discharge valves 16, 20 are closed,  and each valve open at the end of pressing of the auxiliary vessels 15, 19, measured object 2 and reference vessel 3, is closed and left for a given time. After that,  the leakage from measured object 2 is made, and decrease in the pressure is measured at the leakage measuring unit 1. In this case, since the valve 14 is open at  the pressing to measured object 2, the compressed air at greater temperature rise  at the opposite side as the air intake 12 moves in the auxiliary vessel 15, and the  temperature rise of measured object 2 is made very smallthrough enclosed air due to the closing of the valve 14. Accordingly, the measuring error due to temperature change can be reduced.

Abstract: PURPOSE:To equalize all adjacent magnetic area, and to improve electrical characteristics by making a pitch P between slots simultaneously punched pi.(Ri+ Ro)/n (n: the number of slots and Ri, Ro: the inside diameter and outside diameter of the wound core).

Inventor: HIBINO SATOSHI
IPC: C23C14/08
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To reduce the fluctuation of film characteristics and furthermore, to improve the safety in a sputtering method in which a film of titanium oxynitride or the like is formed. SOLUTION: As a sputtering target 28, a titanium target in which the content of oxygen lies in the range of 15 to 35 wt.% is used. This titanium target can be formed by a powder metallurgical method using high purity titanium powder and high purity titanium oxide powder on the market as the raw material. As the gas G, gaseous Ar, gaseous N2 or a gaseous mixture of Ar+N2 is used, but, a trace amt. of gaseous O2 may be added thereto. Since the amt. of gaseous O2 used is zero or small, the dispersion in sheet resistance, reflectance or the like in the wafer face is small, and there is no danger of explosion caused by the formation of ozone even if a cryopump 32 is used. This sputtering method is suitable for forming a barrier film, a W-adhered film, an antireflection film or the like in the formation of wiring in LSI or the like.

Abstract: PURPOSE:To reduce deterioration in picture quality due to a cross-color fault by detecting a luminance signal component mixed in a chrominance signal side accidentally, and lowering the level of a chrominance signal to be outputted when the signal component is detected. CONSTITUTION:An amplitude control circuit 5 performs the multiplication C1XR3 of the chrominance signal (C signal) C1 inputted to a terminal 26 and a signal R3 inputted to a terminal 27 by a multiplier 28, and outputs a result from a terminal 29. The amplitude of the C signal C1 can be controlled by the signal R3 by performing such multiplication C1XR3. The C signal can be obtained from a terminal 30 after controlling the amplitude of the C signal C1 in such way. Also, the luminance signal (Y signal) component Y0 outputted from a Y/C separation circuit 10 can be obtained from a terminal 32 after being phase-adjusted at a phase adjusting circuit 31 by the computing time of adders 13 and 14, a comparator 17, and the amplitude control circuit 25. By performing such operation, the amplitude of the C signal component to be outputted can be lowered when the Y signal component mixed in the chrominance signal side accidentally is detected and the signal component is detected.

Title: Current measuring device
Inventor: MIYAKE TOSHIYUKI
IPC: G01R15/08
Filed: 1980-07-31
Abstract: PURPOSE:To enable lengthening of a measuring time and the improvement of a precision, by a method wherein, when an output of an integrating capacitor, whereto a voltage corresponding to a measurement current is applied, is produced into a given level, a reference voltage is applied in an overlapping manner to the capacitor. CONSTITUTION:With a switch 7 closed, a measurement current 1 flows to a load resistance 2, and voltages at the opposite ends of the resistor 2 are integrated by means of integrating circuits 4, 5, and 6. If an output of an operational amplifier 4 reaches a voltage of a reference voltage source 31, a comparator 32 actuates, a  switch 8a is closed and a switch 8b is opened through a program-setting circuit 13  to flow a reference current 9 to the load resistance 2, and simultaneously, to open a  gate 15. After a given time has elapsed after measurement starts, the switch 7a  opens and 7b closes, and at the point of time when the output of the operational  amplifier 4 is brought into a null position, the gate 15 closes. A clock pulse from a  pulse generator 14, passing through the gate 15, is counted to measure a measurement current. This increases a ratio of the measurement time to a measuring period, and permits the reduction of the influence exerted by disturbance.
