Title: Physical random number generation device and method therefor, and physical random number recording medium
Inventor: ONODERA TORU
IPC: H03M1/10
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To increase the generating speed of physical random numbers and also to secure the good characteristics for the random numbers by providing the random number data based on the digital value which are converted by an A/D conversion means. SOLUTION: Noise signals 102 which are generated from a noise source 101 due to a random event are amplified up to the conversion range of an A/D converter 105 by an AC coupling amplifier 103. Thus, the digital data are obtained and the random number data are generated from the digital data. A piece of random number data is obtained via a single conversion operation by applying the A/D conversion to the amplified signals 102 not by counting the random pulses of signals 102. Furthermore, the random number data of many bits are generated by the converter 105 and in a single A/D conversion operation. Thus, it is possible to obtain the random number data having no periodicity, to fast generate the physical random numbers and also to simplify the circuit constitution.

Title: Package for semiconductor laser device
Inventor: HAYANO FUMIHIKO
IPC: H01S5/00
Filed: 1986-10-20
Abstract: PURPOSE:To reduce a noise caused by a laser beam reflected by a substrate and obtain a semiconductor laser device package with high reliability by a method wherein a semiconductor laser element is attached to the junction surface of the substrate and the part of the surface of the substrate vertically below the semiconductor laser element is so formed as not to have a flat surface perpendicular to the junction surface. CONSTITUTION:The surface of an uneven part 28a formed at the base part of a junction surface 14 on a substrate 10 is inclined so as to become lower from a recessed part 18 toward the junction surface 14. A laser beam emitted from a semiconductor element 16 downward is reflected toward the junction surface 14 by the uneven part 28a. Therefore, the laser beam is not reflected vertically straight upward like a conventional case and an optical system is protected from incidence of the reflected beam. Even if the laser beam enters the optical system by scattering, the laser beam is attenuated by the scattering so that a noise can be suppressed below a certain level.

IPC: B65H59/16
Filed: 1994-09-19
Abstract: PURPOSE: To effectively reduce fluff and to manufacture yarn the surface of which is smooth by arranging a twist stopping member downstream from a twisting member. CONSTITUTION: Yarn (y) is certainly and effectively twisted between a twisting member T and a twist stopping member S as a twist twisted by the twisting member T is avoided from propagating in the downstream direction of the twist setting member S by the twist setting member S consisting of a washer member s1 and guide members s2, s2. Consequently, fluff coming out of the surface of the yarn (y) is rolled in the yarn (y), and the yarn (y) with fluff reduced is formed, The yarn (y) with fluff reduced as fluff is rolled in the yarn (y) between the twisting member T and the twist setting member S prevents fluff from coming out of the surface of the yarn (y) even when the twist twisted through the twisting member T is untwisted, and it is possible to acquire the yarn (y) the surface of which is smooth.  Additionally, residual torque which the yarn (y) has is untwisted after passing the twisting member T and is lost.

Abstract: PURPOSE:To improve the white color uniformity of a phosphor membrane and to make the setting of a light quantity regulating filter to an exposure device easy by specifying the extinction coefficient at the near ultraviolet area of a glass material used for a correction lens. CONSTITUTION:As a correction lens 2, a glass material whose extinction coefficient at the near ultraviolet area exceeds 0.01 is used.

As a result, the transmissivity curve is made in a gentle line, no inflection is generated on the curve, and no unevenness of an exposure membrane is presented,improving the white color uniformity. And since the illumination at the four corners of a face panel 4 can be balanced easily, the setting of the light quantity regulating filter 3 to the exposure device can be made easily.

Abstract: PURPOSE:To industrially obtain the subject fiber having a high tenacity and elastic modulus from as homogeneous a gel fiber as possible at a low cost by subjecting a PVA-based polymer to gel spinning by a specific method and drawing the resultant yarn at a high draw ratio under specific conditions. CONSTITUTION:A PVA-based polymer having >=1700 average polymerization degree and >=95mol% saponification degree is initially dissolved in a solvent (e.g., ethylene glycol) capable of gelling by cooling to prepare a spinning solu tion, which is then subjected to gel spinning at <=20 deg.C using a coagulation bath consisting of an aqueous solution containing >=100g/l alkali by a dry-jet wet spinning method.

Title: Method and circuit for driving cathode luminescence lighting system
Inventor: ICHINOSE SHUICHI
IPC: H05B41/24
Filed: 1993-10-06
Abstract: PURPOSE:To provide a driving circuit by which the ON time of a cathode luminescence type lighting system can be variably adjusted and the life of the system can be kept long. CONSTITUTION:In a lighting system, electrons are released from a Joule heated cathode to an anode and collide with an anode-side phosphor to cause luminescence. In a method for driving the lighting system, the heating time (th) during which the cathode is heated by transmitting power thereto, the ON time (ton) during which power is not transmitted to the cathode but only electron emission is caused to cause luminescence, and a dummy time (td) during which power is not transmitted to the cathode and no luminescence is caused, are repeated in a fixed lighting period (t0). For the variable adjustment of the ON time (ton), the amount of change of the ON time is canceled out by the dummy time (td) so that the heating time (th) is held constant. The ON time (ton) is controlled at a timing independent of that of the heating time (th), and controlling the heating time (th) at timing dependent on that timing facilitates the timing control of the ON time (ton).
