Title: Gas flow velocity measuring apparatus
Inventor: NAGANO MIKI
IPC: G01P5/165
Filed: 1983-11-08
Abstract: PURPOSE:To make it possible to accurately measure the flow velocity of gas by a Pitot pipe even if generated gas is discharged in a turblance state, by using the Pitot pipe and a measuring jig. CONSTITUTION:Measuring openings 23, 24 provided to the leading ends of Pitot pipes 2, 3 are respectively opened upwardly and downwardly. A measuring container 5 consists of an upper cylinder 10 and a lower cylinder 11 so as to form a telescopic structure freely extensible and contractable in an up-and-down direction and is opened in an up-and-down direction. Flow distributing plates 6 have function for distributing a gas stream flowed into the container 5 and are arranged vertically in a crosswise pattern from a plan view in the lower part of the lower cylinder 11. Because the gas stream flowed into the container 5 is rectified by the flow straightening vane 6 and reaches the measuring openings 23, 24 of the Pitot pipes 2, 3, the flow velocity of the gas stream can be measured stably and accurately at a desired place by the Pitot pipes 2, 3.

IPC: B23K26/064
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To provide an optical axis covering device of a laser beam machine which is inexpensive and capable of following the high speed machining. SOLUTION: When a work is laser beam machined by moving a laser beam machining head to the prescribed position, the laser beam LB which is oscillated by a laser beam oscillator and advanced in a duct 29 is converted in direction by a bend mirror 31 which is moved inside the duct 29 as the laser beam machining head is moved and led to the laser beam machining head. Because the duct 29 is constantly closed by fire-retarding elastic members provided on each side of an opening part 37 though the opening part is provided in the duct, the laser beam LB is not leaked outside. The laser beam LB which is converted in direction by the bend mirror 31 in the duct 29 is integrated with the bend mirror 31, and led outside of the duct 29 by an optical axis pipe 43 extending to the outside of the duct 29 from a space between the elastic members, and reaches the laser beam machining head.

Title: Radar equipment
Inventor: MASUNO YOSHIKI
IPC: G01S7/36
Filed: 1982-11-30
Abstract: PURPOSE:To enable the detection of an object by using a higher harmonic receiver even when a jamming wave having frequency same to usual transmission frequency gets in, by parallelly arranging a receiver for receiving higher harmonics with transmission frequency other than a receiver for receiving a signal having frequency same to usual transmission frequency. CONSTITUTION:When a jamming wave having frequency same to transmission frequency gets in, a jamming signal and a real receiving signal returned from an object by reflection are mixed in the output of a transmission wave receiver 3 and the detection of the object becomes difficult. In this case, a selection circuit 7 selects the signal of a higher harmonic receiver 6 with respect to only a place where the detection of the object becomes difficult by the information from a jamming wave detecting circuit 8 to send the same to an indicator 4. A transmission signal is a signal obtained by using certain determined frequency but generally contains a considerable higher harmonic component having frequency twice as compared with the transmission frequency. Therefore, the receiving signal returned from the object by reflection also has the twice higher harmonic component other than the transmission frequency component and, if conversion, the amplification and the detection of frequency are subjected to signal treatment by using the higher harmonic receiver 6 for receiving said frequency signal, the object can be detected similarily as the transmission frequency receiver 3.

IPC: H05B3/48
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To provide a ceramic heater preventing the breakage of a heating resistor by preventing the occurrence of cracks from the conduction paths of a ceramic base material. SOLUTION: This ceramic heater is provided with a first ceramic base material 11, a second ceramic base material 12 and a heating resistor 2.

Title: Pwm arithmetic method of voltage type inverter
Inventor: YAMAMOTO YASUHIRO
IPC: H02M7/48
Filed: 1991-08-26
Abstract: PURPOSE:To operate a voltage pattern having a small output-voltage phase error arithmetically even when output voltage is saturated by computing a value obtained by adding a voltage-vector applying time having different phase of 60 deg. and arithmetically operating and acquiring each voltage component ratio for a suynthetic-voltage vector applying time obtained. CONSTITUTION:The added value (t1+t2) of voltage-vector applying time t1 and t2 is acquired. When output voltage is saturated as shown in (t1+t2)>T/2, (t1+t2) is limited in T/2. (t1+t2) is limited in (t1+t2)=T/2, and t1/(t1+t2) is obtained. Formula acquired is changed into a table, and the speed of arithmetic processing is increased. t1 is obtained from the following formulae. t2 is acquired from t1=t1/(t1+t2) and t2=(t1+t2)-t1. Lastly, the time t0 of a zero-voltage vector period is obtained from t0=[T/2-(t1+t2)]/2. The amplitude of output voltage is limited by conducting such arithmetic operation, but a phase error can be eliminated.
