Patent JP-H02246407-A (JP)
Title: Balanced type power combining amplifier
Inventor: IIDA AKIO
IPC: H03F3/20
Filed: 1989-03-18
Abstract: PURPOSE:To reduce the input VSWR by selecting the length of the transmission line among a circulator, a hybrid coupler and a reflection type amplifier so that the phase of the forward propagation is made in-phase and the phase of reverse propagation is made in opposite phase. CONSTITUTION:The forward propagation phases (thetaAF, thetaBF) of reflection type amplifiers 3a, 3b including circulators 4a, 4b are made in phase and the reverse propagation phases (thetaAR, thetaBR) are made in opposite phase. Thus, the power reflected from a load 6 is distributed to terminals A, B and inputted to terminals E, F of a power distribution hybrid coupler 1 through the circulators 4a, 4b. In this case, the length of transmission lines 7a-9a is decided so as to have a relation of thetaAR=thetaBR+x to output the power to the terminal D of the power distribution coupler 1 and absorbed in a resistive terminator 5a. Since the reflected power from the load 6 is not outputted at a terminal C, the input VSWR is reduced.

Title: Tape cartridge driving device
Inventor: FRED O STEPHANS
IPC: H02K9/02
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To enable miniaturization and simplification by constituting so that a rotator directly drives the capstan of a mini-cartridge using a small size of external rotator motor. SOLUTION: The capstan is directly driven with a high frictional band 500 in the rotator 502 of the external rotator motor. The motor 502 is installed on a metal plate 504 and the metal plate 504 is biased toward the part of a chassis 508 with a spring 506. When the cartridge 100 is completely inserted, the capstan 102 is brought into contact with the high frictional band 500 and the metal plate 504 is pressed so as to leave a chassis stop. At this time, the high frictional band 500 is pressed toward the capstan 102 with the spring 506, whereby the frictional force is maintained. In the small size of motor, the internal stator is extended into a metal supporting plate to transmit heat to the supporting plate. The cooling air by circulation is made to flow in the space between the rotator 502 and the supporting plate.

Title: Extraction of formaldehyde from formalin
Inventor: YAMAMOTO TAMECHIKA
IPC: C07C47/058
Filed: 1979-06-01
Abstract: PURPOSE: To prepare nearly anhydrous formaldehyde, continuously, with a comparatively simple method without treating a solid, by extracting formalin with a non-polar solvent at high temperature.  
     CONSTITUTION: Highly concentrated formalin is fed from the pipe 1 under pressure and transferred to the top of the extraction column 4 through the heat exchanger 2 and the heater 3. A non-polar solvent is fed from the tank 5 to the bottom of the extraction column 4 through the heat exchanger 7 and the heater 8. The both components are flowed in the column to transfer formaldehyde into the solvent and also to progress depolymerization of a polyoxymethylene glycol in formalin. Fomalin having a lowered concentration is taken out from the column bottom 9, cooled and returned t the production unit of formalin. The formaldehyde-containing solvent is taken out from the column top 11 and cooled. The pressure is reduced to the atmospheric pressure by the valve 13 and formaldehyde is recovered from the pipe 14. Preferably the extraction solvent is the one which hardly vaporizes together with formaldehyde and has a lower vapor pressure under extraction conditions.

Title: Parallel operation device for ac generator
Inventor: KIMURA TOSHIMITSU
IPC: H02J3/40
Filed: 1978-06-07
Abstract: PURPOSE: To prevent automatically transversal flow by the procedure in which a fixed bias is applied to automatic voltage regulator in exciter so as to equalize generator voltage with bus voltage in making parallel operation and after making, it is switched to other fixed bias.  
     CONSTITUTION: When the transversal flow during parallel operation of the AC generator 6 whose load share is controlled by speed control of prime mover is detected by the transversal flow detection transformer 3 and then compensated by the exciter 5, the load characteristic of the generator 6 is transferred by operating the voltage setting device 15 of the automatic voltage regulator 14 built in the exciter 5 by the voltage-setting operator 16. Thus, the transversal flow can be automatically prevented only by providing additionally a simple circuit by making connection after generator voltage is equalized with bus voltage when making parallel operation by the regulator 1 and after the making, it is switched to other bias by the voltage-setting operator 16.

IPC: H01J31/15
Filed: 1989-03-20
Abstract: PURPOSE:To prevent explosive shrinkage by forming spacer stripes which reach an address electrode substrate in projecting way along with both sides of each filament cathode. CONSTITUTION:Spacer stripes 30 reaching an address electrode substrate 12 are formed in projecting way along with every one or a plurality of linear filament cathodes 14 in a back side panel 16. The spacer stripes 30 in the back side panel support the address substrate 12 and keep a constant distance between the address substrate 12 and each of cathodes 14 and prevent electron beams from transferring to next triplets passing the spacer stripes 30 by restricting the movement of electrons discharged from the cathode 14 to within a corresponding triplet area. Moreover, the spacer stripes in the back side panel improve the mechanical bending strength of the back side panel and improve the threshold pressure against compression due to atmospheric pressure. By this method, explosive shrinkage is prevented.
