Title: Extremely small diameter optical fiber cord and its manufacture
Inventor: SHIMOMICHI TAKESHI
IPC: C03C25/10
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To obtain a fiber cord which has the outside diameter approximately equal to the outside diameter of an optical fiber and is free of the degradation in various characteristics, such as side pressure characteristic, by disposing a buffer layer 12 of a low Young's modulus corresponding to a primary coating layer on a bare optical fiber and forming a fiber reinforcing coating layer by a continuous stage (tandem) directly thereon. SOLUTION: The buffer layer 12 is disposed on the bare optical fiber 11. The buffer layer 12 consists of a resin consisting of a UV curing type resin, silicone resin, etc., and having the low Young's modulus after curing. The buffer layer 12 absorbs and relieves external force and prevents the external force from acting on the bare optical fiber 11. The fiber reinforcing coating layer 13 is disposed on the buffer layer 12, by which the optical fiber cord of <=300 μm in the outside diameter is constituted. The fiber reinforcing coating layer 13 is obtd. by placing reinforcing fibers of an extremely small diameter, such as glass fibers, aramid fibers, carbon fibers or fine copper wires, longitudinally along the buffer layer 12, impregnating these fibers with the UV curing resin, epoxy resin, etc., and curing the resin.

Title: Prevention circuit of malfunction of screen search due to speed change of videotape
Inventor: SAI RAKUGI
IPC: G11B27/32
Filed: 1993-11-26
Abstract: PURPOSE: To prevent malfunction generated due to a residual signal and a noise by adjusting the pulse width of a Schmidt trigger according to the size of a control pulse further proportional to the moving speed of a tape. CONSTITUTION: A control signal read from a video tape by an audio control head 1 is amplified by an amplifier 2 and rectangular wave-converted by a Schmidt trigger circuit 3. At that time, index information using duty is included in the rectangular wave. Then, this rectangular wave signal is inputted to a VIS operating circuit 4 and a VIS function is executed. On the other hand, a microprocessor 5 provides each kind of speed signal of a video tape to the Schmidt trigger circuit 3, and the circuit 3 adjusts a trigger width by using this. That is, the Schmidt trigger width at the time of the forwarding high speed winding/rewinding of the tape is changed so as to be larger than a noise or a residual signal and smaller than the control pulse, and the VIS operating circuit 4 is operated only by the control pulse.

Title: Malfunction preventing circuit
Inventor: SAKURAI ATSUSHI
IPC: H04N5/073
Filed: 1985-12-24
Abstract: PURPOSE:To prevent runaway and the destruction of a storage content due to abnormal vertical synchronization from occurring by providing a monostable circuit which is triggered by a vertical synchronizing signal separated from a television signal to output a pulse of a pulse-width slightly shorter than the period of a normal vertical synchronizing signal and a gate circuit which passes only such vertical synchronizing signal that has normal or close-to-normal period. CONSTITUTION:A one-shot circuit 42 is triggered at the falling of a signal EV, and outputs a pulse of constant pulse-width. The Q-output of the circuit 42 is supplied to an AND gate 44. Therefore, if the signal EV passes through it, the said gate 44 closes during the said constant pulse-width. When plural signals equivalent to vertical synchronizing signal are generated within the one period (16.6mS) of the vertical synchronizing signal during normal time, ones, among the said signals, whose periods are less than 90% of that of the vertical synchronizing signal can not pass the gate 44 but cut off. Thus only the vertical synchronizing signals having an interval approximately equal to one period are made pass the gate 44. Therefore, such vertical synchronizing signals as having abnormally short period are blocked and can not enter the internal of a personal computer.

Title: Silicon semiconductor substrate and manufacture thereof
Inventor: IKARI ATSUSHI
IPC: C30B29/06
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To fabricate a silicon semiconductor substrate having crystal defects not exceeding 10<-1> /cm2 on the substrate surface, by using a safe rare gas atmosphere. SOLUTION: A silicon semiconductor substrate is subjected to heat treatment for more than one hour in a rare gas atmosphere having an impurity content of 5 ppm or less at a temperature of not less than 1000 deg.C and not exceeding 1300 deg.C, thereby forming a high quality DZ layer (non-defect layer). Generally, argon gas is used as the rare gas. When an oxide film on the substrate surface is rendered so thin as to have a thickness of 1 nm or less prior to heat treatment, a stable effect of reducing crystal defects is obtained. Such a defect reducing effect is further enhanced by using a silicon semiconductor substrate employing a silicon single crystal prepared by the Czochra ski method and pulled at a velocity of 1.5 mm/min or more, or by providing a purge box at the entrance of a heat treating furnace to render the impurity concentration of the atmosphere in the furnace to be 5 ppm or less.
