IPC: D01F9/22
Filed: 1995-02-07
Abstract: PURPOSE: To produce a high-modulus carbon fiber capable of exhibiting excellent compression modulus when processed into a composite material by subjecting a precursor to graphitization in the presence of boron in a rare gas atmosphere free from nitrogen. CONSTITUTION: A precursor is produced by wet-dry spinning of a spinning stock solution containing 20% of a polymer prepared by solution polymerization of 98% of acrylonitrile with 2% of methacrylonitrile in dimethyl sulfoxide solvent, coagulating the spun material in an aqueous solution of dimethyl sulfoxide, washing it with water, subjecting to drawing, applying oil, drying to make condensed and further subjecting to steam drawing. The obtained precursor is made to flame resistant by heating in air and subjecting to graphitization at >=2000 deg.C in an argon gas atmosphere substantially free from nitrogen in the presence of baron.  The obtained high modulus carbon fiber contains >=0.1% of boron and has tensile modulus of >=35×10<3> kgf/mm<2> , interlaminar shear strength of >=5kgf/mm<2> and B/C and N/C ratios determined by photoelectric spectrometry of >=0.0005 and <=0.1000, respectively.

Title: Roll material having excellent cutting property and wear resistance
Inventor: YAEGASHI TOSHIO
IPC: C22C38/30
Filed: 1980-02-20
Abstract: PURPOSE: To enhance the cutting property and wear resistance of a roll material for Sendzimir mill by reducing the amount of V contained in an M-15 type high-speed steel-based roll material and also increasing its Si content.  
     CONSTITUTION: An alloy steel, containing 1W1.5% C, 0.8W1.2% Si, 0.3W0.6% Mn, 3.5W5% Cr, 3.5W5% Mo, 2W3% V, 5W7% W, and <5% Co, is used as a roll material for Sendzimir mill. In this case, the V content of the M-15 type high- speed steel material being used generally is reduced, that is, the VC content as a hard carbide is reduced in order to raise its grindability. Also, the W content is kept in an amount similar to that of the M-15 type high-speed steel in order to prevent the lowering of its wear resistance, and also the si content is increased in order to improve the heat shock resistance of roll material. Thus, a roll material for Sendzimir mill which is excellent in grindability and wear resistance can be obtained.

Abstract: PURPOSE:To attain call connection between terminal devices having the same attribute by using a connection class data corresponding to plural and different terminal devices provided to a subscriber's controller given with a representative number so as to discriminate an incoming terminal device. CONSTITUTION:The subscriber's controllers TC3, 7 are provided with control circuits CTL30, 70 and terminal attribute tables TCT31, 71 respectively and a terminal class data under the control of the TCT31, 71 is written in the TCT31, 71. In case of incoming connection control via the TC3, when a representative subscriber number A is designated by the incoming number, a CC10 transits the incoming display signal and also caller terminal attribute information to a digital subscriber line loop DSL1. After the CTL30 detects the said incoming display signal in the TC3, the caller terminal attribute information is received, the TCT31 is indexed and the terminal class data under the control of the own device is read. When the both are of the same attribute, the CTL30 connects the incoming call to a TLX2. When the data of the same attribute is not read, the CTL30 gives a connection disable signal and informs it to the caller terminal device.

Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To loosen pulsation by respectively regulation stroke of pistons, and arranging control means for regulating a liquid rate respectively discharged by pistons at the time of a pump cycle. SOLUTION: Two sapphire pistons 10, 20 of two pump units are driven using ball screw driving per piston. When a pump is operated, a distance where the pistons 10, 10 are moved between a top dead center and a bottom dead center is calculated by a system controller 41 utilizing a prescribed mathematical relation between a flow rate and a stroke length selected in the user interface 42 by a user. Simultaneously therewith, a frequency of reciprocating motion of the pistons 10, 20 is decided according to the selected flow rate in the system controller 41. Since control of the flow rate is carried out by switching a stroke frequency and a stroke capacity of the pump simultaneously, pulsation in relation to a pump output is substantially eliminated.

Title: Controller of light quantity
Inventor: USHIO YUKIHIDE
IPC: G11B7/126
Filed: 1983-02-10
Abstract: PURPOSE:To attain the optimum control on a light quantity by using a means which switches in steps the emitted laser light quantity and then controls the light quantity continuously. CONSTITUTION:A laser generator 1 delivers the front and back beams and controls the beam radiation intensity by means of the intensity detecting signal of the back beam. A counter 16 starts counting with a timing signal TS, and a current switch 19 is turned on. Thus the count value of the counter 16 is set equal to the current value to be supplied to the generator 1. The generator 1 emits the light when the current reaches the threshold value ITH. A comparator 14 compares the reference value corresponding to the drum sensitivity decided by a reference level circuit 13 with the output of a photodetecting circuit 11. Then the counter 16 stops its counting action when the output of the circuit 11 reaches the reference value and an FF15 is reset. The count value obtained at that time point is held. At the same time, the output of an OFF circuit 21 is also switched to VIDEO and the generator 1 blinks synchronously with the VIDEO. The generator 1 keeps a fixed level of light quantity until the FF15 is set by the signal TS which is supplied next.

IPC: G11B7/09
Filed: 1988-01-29
Abstract: PURPOSE:To prevent operator's erroneous judgement in case of the occurrence of surface inclination due to a factor other than the defect of an optical disk itself by detecting and displaying that a tracking error signal continuously exceeds a prescribed value. CONSTITUTION:The laser light from a light source 1 is reflected on a surface 8 of an optical disk 7 and is focused on the center part of a four-divided photo diode 11 through a beam splitter 4, a knife edge 10 which intercepts the upper half of the light, etc. Though output RF and TE signals of the diode 11 indicate fixed values when the laser light as the checking light is in the in-focus state to perform tracking, thee signals exceed specific threshold values when the laser light traverses a groove or is inclined, and this state is detected by values of these signals. The surface inclination of the optical disk to a drive table is displayed when these values continuously exceed prescribed values, thus preventing the operator from erroneously judging the optical disk itself to be defective.
