Title: Manufacture of silicon carbide whiskers
Inventor: YAMADA JIUTAROU
IPC: C30B25/00
Filed: 1981-09-14
Abstract: PURPOSE:To reduce an amount of granular silicon carbide impurity, by substituting a specified range of amount of grain hull ashes for very fine powder of silica in manufacturing silicon carbide whiskers by mixing a specified amount of carbon black with hull ashes, filling a reaction vessel with the mixture, and heating it at a specified temp. in a nonoxidative atmosphere. CONSTITUTION:10-30wt% of hull ashes used for silicon source is substituted for very fine silica powder having 7-40mum primary particle diameter. With this mixture, 110-400wt% carbon black is mixed based on the ashes and silica, and filled into a graphite reaction vessel. The inside of the vessel is substituted by a nonoxidative gas, then, current is passed through the vessel to maintain it at 1,300-1,700 deg.C for at least 2hr, resulting in producing high quality silicon carbide whiskers containing very little granular silicon carbide impurity. Addition of 80-200wt% halogenides of alkali metals or alkali earth metals elevates efficiency based on the ashes and silica.

Title: Scanning picture recording system
Inventor: SHIODA KAZUO
IPC: H04N1/04
Filed: 1978-11-21
Abstract: PURPOSE: To increase easily the gradation reproducibility without impairing the resolution by increasing the width of the horizontal scanning line through minute up-down vibration of the scanning beam and thus eliminating the gap between the scanning lines.  
     CONSTITUTION: Both horizontal and vertical synchronous signals are drawn out of the video signals supplied to synchronous isolator circuit 10. Then the horizontal synchronous signal generates the saw-tooth type horizontal deflection signal through horizontal deflection circuit 11; while the vertical synchronous signal generates the vertical deflection signal through vertical deflection circuit 12 respectively. The vertical deflection signal is supplied to piling circuit 14 along with the high-frequency output signal of high-frequency signal circuit 13 for piling and then supplied to the vertical deflecting electromagnetic coil of CRT15. On the other hand, the electron beam radiated from the electronic gun of CRT15 is deflected by the horizontal and vertical deflection signals to display the picture on the fluorescent screen. In this case, however, the scanning line features the wave line since the high-frequency signal is piled on the vertical deflection signal. Here if the cycle of the high frequency is set identical to the time during which the beam shifts by the spot size, no vibration emerges to the scanning line to increase virtually the width of the line. Thus a high-contrast picture can be reproduced with no gap caused between the scanning lines.

Title: Image forming device
Inventor: MIYAMOTO TOSHIO
IPC: G03G21/00
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To continuously print image data having different resolution even when they are continuously sent from a host computer by performing preparatory operation so as to change the various kinds of electrophotographic processing conditions corresponding to processing speed after change at the time of switching resolution. SOLUTION: The processing speed is switched to 35mm/sec from 70mm/sec right after the rear end of the first sheet of printing paper (transfer material) passes through a heating fixing device. The redetection of automatic transfer bias applying control is performed for about 1.1 sec after switching the processing speed, and after the completion of the detection, the image write-in of 1200dpi of a second sheet is performed waiting for the completion of the other preparatory operation (after about 2sec). In this case, it takes about 2sec from the cleaning position of a cleaning device 7 to the transfer position of a transfer roller 5 at the processing speed 35mm/sec by the rotation of a photoreceptive drum 1, so that a soiled part passes the transfer position even if defective cleaning is caused.

Abstract: PURPOSE: To prevent a theft of a bicycle, etc., by inserting a fixing rod into a hole formed in a plate linked to a pivot part, and locking one end part of the fixing rod by a locking member so as not to be released from the plate. CONSTITUTION: The bases of arm elements 3a, 3b of a frame mount arm 3 are pivoted on a plate 9 through pivoting pins 8 so that they can free rise and fall on rising ear parts 9a.

CONSTITUTION:A metal-plated nonwoven fabric uses a base as nonwoven fabric consisting chiefly of composite fiber having spiral micro-crimp. wherein the rate of monofiber shall be under 6 deniers. Exceeding 6 deniers is unfavorable because of decrease in the surface area. Binder fibers of hot fusion attaching property included in this composite fibers consist of thermoplastic polymeride which is fusion attached at 110-180 deg.C. A nonwoven fabric hot fixed by the hot fusion attaching binder fiber of at least 5 wt.% is bulky with an apparent density below 0.06 g/cm<2>, which is calculated on the basis of the thickness measured with a load of 2.5 g/cm<2>. and thin, uniform, and lesser in unevenness of metal attachment. Exceeding 0.06 g/cm<2> of nonwoven fibric density causes large thickness deformation in the plating process, and no metal plating of good workmanship is expected.
