Title: Bushing for spinning glass fiber
Inventor: NAKA ATSUSHI
IPC: C03B37/083
Filed: 1990-07-26
Abstract: PURPOSE:To enable to rapidly recover a spinning operation in the stable diameter state of a glass fiber even when the breakage of the glass fiber is generated by forming unevenness with a specific roughness on the outer surfaces of many circular projected nozzles. CONSTITUTION:In a glass fiber-spinning bushing having many circular projected nozzles on the bottom surface of a bushing plate of the bushing, unevenness having a surface roughness of 0.5-50mu is formed on the outer surface of each nozzle. Since the bushing has large melted glass-wetting resistance on the outer surface of each nozzle, the spreading of the wetting of the melted glass on the outer surface of the nozzle can be prevented. Consequently, glass fibers having a high quality can be prepared in high efficiency because the breakage of the glass fibers is minimized. Since the melted glass naturally falls from the nozzles even when the glass fibers are broken, the melted glass can be readily drawn out from the nozzles and the spinning operation can be rapidly recovered in a stable diameter state of the glass fibers.

Title: Color liquid crystal display device
Inventor: SAKAMOTO TSUTOMU
IPC: G02F1/133
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To eliminate the necessity of a color switching circuit even though a delta array is selected. SOLUTION: The delta array, in which same color pixels are shifted for equivalent to one and half pixels in top and bottom lines, is selected for liquid crystal display(LCD) panel 11. Signal lines 21 supply primary color signals from an X direction driver 12. The lines 21 connect the signal electrodes of the same color signals which are shifted for equivalent to one and half pixels in the top and bottom lines. Thus, one signal line is supplied with only one primary color signal and color switching circuits are not required.

IPC: B05D7/26
Filed: 1989-08-03
Abstract: A process is described for coating electrically conducting substrates with an insulating coating, which comprises first subjecting silicon compounds which both have groups susceptible to hydrolysis and also contain (organic) radicals accessible to a polymerization to a polycondensation, then depositing the resulting polycondensate on the subtrate and curing the coating so obtained by polymerization involving the organic radicals. If the polycondensate additionally contains groups which are capable of carrying a charge, coating by electrophoretic dip coating is possible.

Filed: 1990-07-27
Abstract: PURPOSE:To keep the thickness of a channel layer constant by forming a first conductivity type high impurity concentration second epitaxial layer on a first epitaxial layer, then diffusing an impurity before etching the second layer, and forming a second conductivity type region. CONSTITUTION:A silicon nitride film is formed as a diffusion mask layer 6 on an n<+> type high concentration GaAs epitaxial layer 4 by a plasma CVD method, etc. Then, a window 7 is opened at the layer 6 by a photoetching method, a p-type-forming impurity such as Zn, Mg, etc., is diffused from the window 7 in an n-type GaAs epitaxial layer 3 through the layer 4 to form a gate diffused part 8. In this case, since the p-type forming impurity is diffused before the layer 4 is etched, the thickness of a channel layer formed under the part 8 is always constant. The diffusing amount of the impurity can be easily controlled different from etching.

Title: Coating composition for synthetic resin foam mold
Inventor: KURODA SUSUMU
IPC: B22C3/00
Filed: 1983-10-26
Abstract: PURPOSE:The titled coating composition useful as a material to represent a shape, such as a casting pattern material, comprising a sythetic resin emulsion or a synthetic rubber latex, a thermosetting resin precondensate, an organic solvent, and calcined gypsum. CONSTITUTION:A synthetic resin emulsion and/or a synthetic rubber latex, a thermosetting resin precondensate, an organic solvent, and calcined gypsum are compounded. The obtained coating composition will have a time of drying and curing adjustable freely in the range of about 5min-3hr by the water content and the amount of a cure regulator (e.g. sodium citrate) in mixing. In addition, a dispersing agent and a stabilizer may be incorporated to increase pot life or to improve workability in coating. The calcined gypsum takes the water from the solution as water of crystallization to be converted into gypsum dihydrate, causing solidification itself; the mixed solution is subjected to dehydration, causing rapid film-forming; and the precondensate is also subjected to dehydration, causing the condensation to be accelerated.

Filed: 1991-08-09
Abstract: PURPOSE:To reduce vibration of a radiation shielding plate and to decrease a quantity of heats generated in a superconducting coil and a frame of the coil by bending the plate and mounting a rib in its recess. CONSTITUTION:A radiation shielding plate 3 is bent, shaped and a rib 5 is mounted in a recess by bending. The two plate 3 are formed in a shielding box 4 with side shielding plates 6 to contain a superconducting coil 1.

Accordingly, an amount of variation in the magnetic field due to the eddy current of the plate 3 is reduced, and the quantity of heats generated from the coil 1 and a helium vessel of a coil frame can be reduced.

IPC: H01Q13/10
Filed: 1990-07-30
Abstract: PURPOSE:To make the frequency characteristic broad by using two orthogonal independent electric fields so as to feed in a square waveguide space in a way that each electric field is propagated symmetrically in the basic mode. CONSTITUTION:Power fed to a coaxial cable as a feeding part 6 is propagated in square waveguides 5a, 5b and the power is fed in a square waveguide space in phase from feeding slots 4a, 4b, propagated from the feeding slot 4a in the basic mode of an electric field Ea in the X direction in the square waveguide space S and propagated from the feeding slot 4b in the basic mode of an electric field Eb in the Y direction in the square waveguide space S. In this case, the feeding power from the feeding slot 4a excites the power radiation slot 1a to allow the power in phase whose electric field direction is Ea to radiate into a free space. Similarly, the feeding power from the feeding slot 4b excites the power radiation slot 1b to allow the power in phase whose electric field direction is Eb to radiate into a free space.

Title: Code phase detection circuit
Inventor: SAGAWA KAZUMI
IPC: H04B1/7075
Filed: 1987-08-14
Abstract: PURPOSE:To shorten a time to detect a phase, by accumulating each chip of an input PN code system and that of a local PN code system in a shift register sequentially, and performing pattern comparison corresponding to the length of the shift register. CONSTITUTION:The local PN code of a D-type flip-flop 6 is compared with the input PN code of an input shift register 1 at every chip by a logic circuit. Also, accumulation data is read out from a RAM9 addressed by an address counter 5, and an adder 8 performs the addition of the data on comparison data, and updates the result in the same address as the accumulation data. An arithmetic control part 10 judges an accumulation data(correlative value) point which becomes maximum in the accumulation data corresponding to each address, and detects that the address shows the correction value of a PN code phase. Therefore, when correction is needed, the addition of a pulse is performed on a pulse addition circuit 11. In such a way, a timing by which a local PN code system is generated can be accelerated, and it is possible to perform the coincidence of the phase of the local PN code system with that of the input PN code system in the phase of the chip.
