Inventor: AOKI HISATOSHI
IPC: H05G1/64
Filed: 1979-02-23
Abstract: PURPOSE: To prevent excessive photograph density caused when the detection area is covered, by comparing the image signal from TV camera with referential signal to produce correction signal from correction circuit and controlling automatic exposure controller.  
     CONSTITUTION: X-rays passes through a person to be inspected lying on the top board 3 of bed and converted through image intensifier 6 into optical image which is distributed through optical system 9 into television camera 7 and photo-electron multiplier 8.

Title: Method and device for inhibiting formation of nox in heat-accumulating burner
Inventor: HOVIS JAMES E
IPC: F23C9/00
Filed: 1989-01-31
Abstract: PURPOSE: To sustain the high efficiency characteristics of a heat storage system by incorporating an NOx suppressing means in a regenerative burner thereby reducing NOx and controlling the temperature and characteristics of flame. CONSTITUTION: Two regenerative burner 14 are coupled with regenerative beds 18, respectively, and combustion air/exhaust gas pass between the burner 14 and a combustion air/exhaust gas passage 16. Combustion air is fed through a blower 20 to one burner having a nozzle 32 for supplying fuel through an opening 34. The combustion air is fed through an inlet opening 36 to a burner 30 and passed through the beds 38, 18. A burner baffle 42 having four holes 44 is disposed contiguously to the nozzle 32 in order to jet the combustion air toward the opening 34. A low voltage region is thereby formed on the baffle plane to cause recirculation of combustion gas to an initial combustion zone thus lowering the flame temperature and reducing NOx in the combustion exhaust gas. The NOx suppressing means may jet fuel through a plurality of inclining fuel holes 56 toward an opening 54.  Fuel hole inclining forward causes recirculation of combustion gas returning back to the initial combustion zone while suppressing NOx.

IPC: H01P1/00
Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To reduce a route difference between hot current and return current by providing a ground pattern and side through holes or upper face ground patterns connected by side.plating on both sides of a strip line positioned in a connection part with an external circuit. SOLUTION: The upper face ground patterns 22 are formed on a low layer dielectric substrate 7 and the ground pattern 11 and the upper ground patterns 22 are connected by the side through holes 23. The strip line pattern 10 and the upper face ground patterns 22 form the coplanar line 24. The strip line patterns 10a and 10b are connected by a gold wire 25, and the upper face ground patterns 22a and 22b are connected by a gold wire 25. When a clearance exists between packages for high frequency circuit, high frequency return current 19 flows through the wire 25. Thus, the route difference with hot current can be suppressed to be about twice as much as the height of the low layer dielectric substrate 7. Consequently, the route difference between hot current and return current can be reduced.

Title: Dielectric filter
Inventor: NAKATSUKA KENJI
IPC: H01P1/205
Filed: 1991-02-13
Abstract: PURPOSE:To facilitate the adjustment to suppress the variance in the resonance frequency by increasing a diameter of a throughhole placed at both ends of a dielectric block in comparison with a diameter of a throughhole placed in the middle. CONSTITUTION:The diameter of cylindrical throughholes 23, 25 of a dielectric block 1 is made larger than the diameter of a throughhole 24. That is, the inner diameter of inner conductors 26d, 28d provided in the inner face to form a resonator is selected larger than the inner diameter of the inner conductor 27d. Thus, the characteristic impedance of the inner conductors 26d, 28d is lower than the inner conductor 2d, the resonance frequency of a 1st stage resonator and a final stage resonator gets higher and the resonance frequency of a 2nd stage resonator is relatively lower. Since the shape of side face electrodes 26b, 26c, 27b, 27c, 28b, 28c is made the same as that in the middle and at both ends, the final adjustment to suppress the dispersion in the resonance frequency is simplified.

Filed: 1990-02-01
Abstract: PURPOSE: To obtain uniform products without necessitating use of seamless tubes as a stating material by drawing a tube stock through a working cross section comprising a die with a grip tongue during rolls are rotated and making them rotate. CONSTITUTION: A metallic tube is inserted into the max. cross-sectional region of the opposed rolls 2 and fixed in a grip tongue 6. When the rolls 2 are rotated, simultaneously drawing action is attendantly caused and the metallic tube is formed into a conical body. Thus, in the case of multistage forming, to obtain extruded products as round and as uniform as possible, the grip tongue is rotated between individual forming stages. Drawing operation during the rolls 2 are rotated is executed by laterally moving a carrage 12 for carrying the rolls 2 in the direction receding from the grip tongue which is rotatable but fixed by operation of a driving device 13 for drawing. By changing the laterally moving speed of the carrage 12 and/or the rotational speed of the rolls 2, the taper angle of a finished product is adjusted, as necessary.
