Title: Production of composite carbon fiber/carbon material
Inventor: KIKUCHI YOSHIHIRO
IPC: C04B35/83
Filed: 1987-11-09
Abstract: PURPOSE:To improve the mechanical strength of a composite carbon fiber/ carbon material by kneading the short fibers of carbon fibers, carbon powder having a specific average particle size and liquid binder respectively at prescribed weight compsn. ratios, then molding and sintering the mixture. CONSTITUTION:100pts.wt. short fibers of the carbon fibers and 10-30pts.wt. carbon powder having <=30mum average particle size are compounded with 100pts. wt. thermosetting resin, etc., such as phenolic resin and the mixture is kneaded at ordinary temp. or in a heated state. The cured mixture is ground and molded the ground powder material and further, the molding is calcined in an inert atmosphere to form the composite carbon fiber/carbon material. The weight compsn. ratio of the carbon powder is confined to 10-30wt. ratio and the average particle size thereof to <=30mum and, therefore, the bonding strengths between the respective component compsns. increase. The mechanical strength of the composite carbon fiber/carbon material is thereby improved.

Filed: 1985-12-18
Abstract: PURPOSE:To make it possible to detect also delay or leading current >=90 deg. by detecting the reactive power of only a load to compensate the variation of reactive power in each half cycle. CONSTITUTION:A current transformer 6 and a resistor 7 generate a voltage signal proportional to a load current iF and input the voltage signal to an adding point 87, a current generating circuit 85 for effective power generates a sine wave having the same phase as that of a voltage waveform and inputs its output to the adding point 87 and a current generating circuit 86 for reactive power generates a sine wave having a phase delayed by 90 deg. from that of the voltage waveform and inputs its output to the adding point 87. The adding point 87 adds these three inputs momentarily and inputs its output to a reactive power detecting circuit 81, which detects reactive power on the basis of the input from the adding point 87 and a voltage signal outputted from a transformer 5 and inputs its output to a subtracting point 89. A reactive power signal generating circuit 88 outputs the same value as the reactive power of the current signal outputted from the circuit 86 and inputs its output to the subtracting point 89. Consequently, the reactive power compensating device reacts so that the reactive power of the load 4 varied in each half cycle is rapidly compensated.

Title: Flash x-ray tube
Inventor: ISOBE HIROSHI
IPC: H01J35/04
Filed: 1989-11-01
Abstract: PURPOSE:To generate a stable-level X-ray output with the aid of a low-level tube voltage by arranging a trigger electrode of specific shape in a specific position. CONSTITUTION:A trigger electrode 4 is in the shape of a crosssectionally unfolded fan and truncated hollow cone, and the thickness thereof is reduced gradually toward the top portion thereof so as to be formed in a knife-edged shape. The trigger electrode 4 is arranged on the opposite side of an anode 3 on a straight line connecting a cathode 2 to the anode 3. A space L2 between the top portion of the trigger electrode 4 and the cathode 2 is equalized to or lessened more than a space L1 between the cathode 2 and the anode 3. When a voltage positive to the cathode 2 is impressed upon the trigger electrode 4, pre-discharge may be consequently generated between the trigger electrode 4 and the cathode 2 to ease the generation of main discharge between both of the anode and the cathode. Thus, a stable-level X-ray output can be obtained with the aid of a low-level tube voltage.

Title: Production of color filter for liquid crystal panel
Inventor: ONO YOSHIHIRO
IPC: G02B5/20
Filed: 1992-10-22
Abstract: PURPOSE:To prevent the influence of the presence of a color filter layer formed as the thinner type than the conventional color filter layer produced by using the pigments alone at the time of driving a liquid crystal by further dispersing conductive materials into this color filter layer, thereby lowering the resistance of the color filter layer. CONSTITUTION:A transparent electrode 12 having transparent electrodes 13 of a prescribed shape and a counter electrode 14 are diagonally immersed into an electrolyte 11. The point B where the counter electrode 14 intersects with the electrolyte surface is required to exist always on the left side of the uppermost end A where the color filter layer is ought to be formed. The reason thereof is to uniformalize the amt. of the conductive particulates to be taken into the color filter layer within the plane of the color filter layer when the conductive particulates in the electrolyte 11 settle at a specified speed and the color filter layer is formed. Namely, the color filter layer is the film deposited with org. pigment particles and, therefore, the porous film structure having the many gaps among the particles is obtd. Then, the intrusion of the conductive particulates into these gaps is possible. The resistance of an insulator or the org. pigment layer having the electric resistance approximate to the electric resistance of the insulator is lowered.
