PURPOSE:To obtain an excellent cut section of an optical fiber by applying tensile force to the optical fiber when cutting the fiber by using a CO2 laser, and setting the length of elongation by the tensile force to once - twice a laser beam diameter. CONSTITUTION:A CO2 laser oscillator 1 emits a laser beam L whose diameter is set greater than at least the diameter of the optical fiber 1, and a co...

PURPOSE:To obtain a sintered product which has a through-hole of an optional shape easily, by embedding a low m.p. metallic member having a desired shape in the powder for forming a sintered body and compacting the same to a green compact then sintering the same. CONSTITUTION:Mixed powder for forming a sintered body is packed on the lower punch 3 in a master die 2. A low m.p. metallic member of a ...

PURPOSE:To realize an independent operation within a limited range for a multiplex device whose systems are driven in parallel, by producing a fault detecting signal after comparing the data between own system and another system and counting the frequencies of continuous dissidence of the comparison. CONSTITUTION:When the data and the address of a 2-system S2 are fed to an interface 7 of another s...

In addition, a method for forming said expanded and cured polyester resin composition, and the product formed in accordance with said method, an expanded and cured polyester...

Polyester resin is expanded and cured using mono-substituted sulfonyl hydrozide blowing agent, organic peroxide curative and certain metal promoters.

PURPOSE:To improve the efficiency for starting and releasing of an instruction, by detecting the end of reading of a vector register and then releasing an operator and a memory requester. CONSTITUTION:When an instruction is started to transfer a vector data to a vector register from a main storage, the writing is carried out to a vector register 4 from an instruction control unit 3 via a signal li...

The invention relates to an electronic stylus for digitizing devices usable for designing and digitizing. A fine-lead unit 1 with lead storage chamber 8 and advanceable graphite lead 7 is arranged in a carrier tube 2; the lead guide means 32 is surrounded by a detachable induction coil 31, by means of which the digitizing device is activated. A combined contact and on-off switch, constructed with ...

1. Process for mixing liquids with gases, for introducing gases into a liquid below its liquid level, in which the gas as well as the liquid are supplied to a nozzle (4) under pressure, characterised in that the liquid jet is introduced by guide means in a manner such that it shrouds at least partially the gas jet at the lastest at the exit end of the nozzle (4) whereupon the dispersion of the gas...

1. Process for the control of an air or oxygen feed in a jet mixing aeration plant in which the introduced air or oxygen is ejected in a manner such that the gas jet is at least partially shrouded by the liquid jet, characterised in that the amount of process water supplied to the nozzles is kept constant at a predetermined value (4) and only the amount of gas is varied, the amount of process wate...

PURPOSE:To accelerate a cue operation and at the same time to eliminate a data region for link field by executing the cue operation with a hardware in an operating system. CONSTITUTION:A cue control storage device is provided with a cue memory part 1 which stores a data block address and a cue control part 2 which produces a control signal to control the memory part 1. When an operating indication...

PURPOSE:To prevent the operation of a focus controlling system from being unstable even with the beam amount changed, by irradiating the beam of a prescribed wavelength by a laser light emitting device and irradiating the reflected light on a detector provided with plural photodetecting parts. CONSTITUTION:Even if the amount of light applied to a photodetector 17 without focus error is changed, th...

PURPOSE:To prevent the operation of focus and tracking controlling systems from being unstable, even if the beam amount reflected on a disc and applied to a detector is changed, by compensating differences in sensitivity of respective photodetecting parts of a detector. CONSTITUTION:The state where no focus error and tracking error exist is detected. In this case, the output level of adders 41 and...

PURPOSE:To reduce the number of components and to simplify the circuit, by designating an output of a comparator as a sample holding signal without sample holding the output with the rising and falling pulses, in an optical video disc player and a digital audio disc player. CONSTITUTION:In a figure, no rising and falling pulse generator is used, an output of the comparator 5 is given to a sample h...
