Title: Heat transfer pipe for heat exchanger and manufacture thereof
Inventor: MINAMOTO KENKI
IPC: F28F1/00
Filed: 1989-05-02
Abstract: PURPOSE:To obtain excellent corrosionproofing performance against sea water and to prevent noise from generating at the time of inspecting vortex flow deep flaw by forming a film containing iron hydroxide or iron oxide as a main ingredient and specific permeability on the inner face of a heat transfer pipe. CONSTITUTION:After iron powder suspension is adhered to the inner face of a heat transfer pipe for a heat exchanger, oxidative gas of 0.1 to 32.0 mmHg of steam partial pressure is passed at the flowing velocity of 2 ml/min to 90l/min per 1cm of inner diameter of the pipe through the pipe to form a film containing iron hydroxide or ion oxide as a main ingredient. Thus, after iron powder suspension is adhered to the inner face of the heat transfer pipe for the heat exchanger, the water content and air flowing rate in the oxidative gas to be fed in the pipe are controlled to suitable ranges thereby to accelerate the oxidation reaction of the iron powder to reduce the remaining metal iron. Thus, the permeability of the film can be regulated to a small value such as 1.00 to 1.15.

Abstract: PURPOSE:To reduce visual out-of-focus easy to be recognized at a place conditional change of which is hard by controlling luminous level change when a video signal changes from a still condition to a moving condition or in the opposite case of it so as to be comparatively gradual. CONSTITUTION:A temporal interpolating circuit 1 of a still picture processing system and an interpolating within field circuit 2 of a moving picture processing system are provided to an input video signal and respective outputs are mixed moderately by a movement detecting signal with a mixer 3. The output of the mixer 3 is added with a correcting signal in an adder 10 and an output video signal is obtained. Then, the output of the temporal interpolating circuit 1 of the still picture processing circuit is supplied to a frequency difference extracting circuit 4, the part of a difference with the reproducing frequency band of the moving picture processing system is extracted and the output of the frequency difference extracting circuit 4 is attenuated by a multiplier 7. Thus, it becomes hard to feel as out-of focus by reducing the level change when it moves from a still condition to a moving condition.

Abstract: PURPOSE:To obtain a polyglycidyl ether derivative providing a comb shaped polymer expectable for application to polymer electrolyte. CONSTITUTION:A polyglycidyl ether derivative of formula I (R is H or methyl; R' is alkyl; Ar is phenyl; m is 2-10,000). The compound is homopolymerized or copolymerized with another vinyl monomer to give a comb shaped polymer of formula II (X is monofunctional organic group; n is 2-10,000; p is 0-10,000). The compound of formula I is obtained by hydrolyzing a polyglycidyl ether containing a silyloxy group at one end of formula III with an acid to give a polyglycidyl ether containing a hydroxyl group at one end of formula IV and reacting the polyglycidyl group with a vinyl-containing acid halide.

Filed: 1978-09-18
Abstract: PURPOSE: To adapt machining, working, assembling and maintenace to be easy by arranging so as to eliminate positional binding among a pressing down screw that is horizontally installed and moves toward the axis direction accompanied with revolution, a metal chunck and a carrier bar.  
     CONSTITUTION: The revolution of a motor and a worm gear shown in the schematic diagram is transmitted, and a pressing down screw 33 turns. Also, through a pressing down female thread 40, the pressing down screw 33 moves in the left and right directions while truning. A metal chuck 32, a carrier bar 37 and a guide 43 ride the upper part of a housing 34, each slides independently to the axis direction of the pressing down screw 33, and at the same time, its slide part also is guided by the housing 34. Through this method, because exchange of a roll is implemented only by a balance cylinder, it can be carried out with simplicity and promptness. Further, as an eccentric load is not generated on an antifliction bearing, what has a small capacity can manage it.

Title: Suction/exhaust valve for reciprocal engine
Inventor: KAWASAKI SHIYUUICHI
IPC: F01L1/32
Filed: 1983-06-25
Abstract: PURPOSE:To reduce the flow resistance of suction and exhaust by forming oval suction/exhaust ports and rotating the suction/exhaust valve around the axis when lifting said valve. CONSTITUTION:The umbrella section and the suction port 20 of a suction valve 19 are formed oval while a screw 18 is provided such that the valve 19 will rotate around the axis when the valve 19 is driven by the cam 16 and lifts. Consequently, upon lifting of the valve 19, the umbrella section of valve and the suction port 20 are shifted through relative rotation. Since the suction air will flow directly into the combustion chamber without hindrance of umbrella section, the area will be increased to reduce the flow resistance resulting in improvement of suction efficiency. This arrangement can be employed in the exhaust valve to improve the exhaust efficiency.

Title: Tdd system communication equipment
Inventor: KIKUCHI JIRO
IPC: H04B1/48
Filed: 1994-04-28
Abstract: PURPOSE:To prevent an RF amplifier section and a mixer from being saturated by allowing an antenna changeover section to act like a high frequency attenuator at the reception of an excess signal thereby receiving the attenuated reception signal. CONSTITUTION:When a high level control signal is applied to a control input terminal 54, a transistor(TR) TR1 is conductive and a control output terminal 56 connects to ground by the TR 1 and an output goes to a low level. Then a reverse bias voltage is applied to a diode D1, which is nonconductive and a diode D2 is conductive by a forward bias voltage. As a result, an antenna connection terminal 41 and a transmission section terminal 51 are interrupted by the diode D1 and the antenna connection terminal 41 and a reception terminal 52 are connected via capacitors C1, C3 and the diode D2. Furthermore, when the diodes D1, D2 are not conductive, since a very small capacitance is in existence between their electrodes, the reception signal and the transmission wave are not completely interrupted but pass with an attenuation of nearly 20dB. Thus, the antenna changeover device 8 acts like a high frequency attenuator whose attenuation is 20dB between the antenna and the RF amplifier.
