Title: Method for generating random number
Inventor: SAITO YOSHIAKI
IPC: G09C1/00
Filed: 1999-04-07
Abstract: PROBLEM TO BE SOLVED: To generate a complete random number that does not have any periodicity. SOLUTION: First and second parametron oscillators 11 and 12 in which thermal noise existing in a circuit when started decides the phase of an oscillation signal to be a 0 phase or a π phase are provided, the 1st oscillator 11 is continuously driven, and the 2nd oscillator 12 is driven intermittently while a switch 17 is turned on/off in synchronization with a clock signal. A differential amplifier 20 takes the differentiation of the oscillation signals of the 1st and 2nd oscillators 11 and 12 and makes them pass through a lowpass filter 21. Further, a random number generation circuit 22 detects the amplitude of a signal detected by a detection circuit with in synchronization with a clock signal and allocates it to a binary number '0' or '1'.

Title: Controlling method of tape winding
Inventor: SATOU SHINICHI
IPC: B65H26/00
Filed: 1982-06-11
Abstract: PURPOSE:To attain the cost-down of the device and to improve the reliability, by comparing a voltage proportional to the rotating speed of a winding reel and a preset value for detecting the falling point of a tape running speed switching point and stopping the winding. CONSTITUTION:A value of a winding tape to the entire length is set to a preset counter of a stop signal generating circuit 6, and a reference voltage value Vs of a reference voltage generator 5b of a falling point detecting circuit 5 is adjusted with a variable resistor 4 so as to be a voltage of a falling point B. The tape winding diameter is increased as a winding small reel winds up a tape and an output voltage VT of a tachogenerator 2 is decreased gradually. When this voltage reaches the Vs of the falling point or below, an output of a comparator 5a is inverted, a coincidence detecting signal Sa of the falling point B is given to a main circuit 7. When the main circuit 7 detects the coincidence detecting signal Sa of the falling point B, the voltage is changed over to a voltage decreased along a prescribed tilted angle, to decrease gradually the tape winding speed. Then, a pulse train generated in response to the amount of tape winding is counted, and when the counted value is coincident with the value corresponding to the entire tape winding amount set in the counter, a stop signal generating circuit 6 gives a stop signal Sb to the main circuit 7.

Title: Microwave sensor
IPC: G01N22/00
Filed: 1992-03-26
Abstract: PURPOSE:To detect, directly, simply and with good responsiveness, the energy amount of microwaves absorbed by an object to be heated by a method wherein a sensor in which a thermistor element provided with leads is enclosed with a wave absorber composed of a ceramic is used. CONSTITUTION:A bead-shaped thermistor element 12 provided with leads 11 is welded to two dumet wires; after that, the element part is covered with, and welded by, a glass. A wave absorber 13 is enclosed in such a way that a ceramic powder provided with one out of a magnetic property and a dielectric property or with both of them is baked to be a tube shape in such a way that the leads 11 are not subjected to microwaves. When the microwaves arrive at a sensor 10, the wave absorber 13 absorbs them and heat is generated. The amount of generated heat is changed so as to correspond to the energy amount of the microwaves, and the electric resistance value of the element 12 is changed. The thermal conductivity, i.e. the thermal responsiveness, of the wave absorber 13 is high, and the microwaves can be detected with high sensitivity. In addition, since the leads 11 are not subjected to the microwaves, the title sensor is not destroyed due to a discharge between the leads 11.

Title: Apparatus for controlling idling speed of engine
Inventor: ARIMA MANABU
IPC: F02D31/00
Filed: 1983-06-06
Abstract: PURPOSE:To increase the speed at which the engine speed is converged to an aimed ilding speed, by setting the control gain for determining a feedback correction value at the time when the engine speed is higher than the aimed idling speed at a greater value than that at the time when the engine speed is lower than the aimed idling speed. CONSTITUTION:A control valve 48 is provided in a by-pass passage 46 which is disposed to by-pass a throttle valve 42 in an intake passage 26. In controlling the control valve 48 by a control unit 52, a feedback control value is selected by use of a feedback correction value determined from the deviation between an aimed idling speed and the actual engine speed detected by an engine-speed sensor 54 and a load correction value determined to correspond to ON-OFF switching of external loads such as a cooler. Here, the control gain for determining the feedback correction value at the time when the engine speed is higher than the aimed idling speed is made greater than that at the time when the engine speed is lower than the aimed idling speed. The control valve 48 is controlled by use of the feedback control value thus obtained.

Filed: 1979-08-07
Abstract: PURPOSE: To minimize the effect owing to the difference in conditions between recording and reconstructing by entering the reference divergent luminous flux nearly perpendicularly into the hologram recording surface at the recording of individual holograms in hologram recording bodies and entering the reconstructing divergent luminous flux nearly perpendicularly into the hologram recording surface at the light scanning.  
     CONSTITUTION: Since the reference light and the reconstructing light are equivalent, the recording or reconstructing light is set in the central part of hologram recording bodies 12, 13 of a hollow cylindrical shape and the divergent luminous flux thereof is entered perpendicularly to the recording surface. Object light may be so determined that the hologram diffracting light to be reconstructed focuses in or out of the divergent region of the reconstructing light A 10 . It is equally well to form a recording body 14 into a hollow truncated conical shape and placing recording and reconstructing light sources on the rotating axis AX10. Or equally good results may be obtained even by using a recording body 15 of a concave shape having a center of curvature on the rotating axis AX10 and reflecting mirrors M1, M2 and entering the luminous flux perpendicularly to the recording surface H. Thereby, the effect owing to the difference in conditions for the substrate at the recording and reconstructing may be minimized.

Title: Driving method for liquid crystal element
Inventor: OGAWA AKIRA
IPC: G09G3/36
Filed: 1986-04-30
Abstract: PURPOSE:To prevent ferroelectric liquid crystal from deteriorating by applying a DC component which is equal to but opposite in polarity in a short-time pulse voltage to the ferroelectric liquid crystal continuously together with the short-time pulse voltage. CONSTITUTION:Pulses which have a voltage lower than a threshold voltage EC are assigned in front of and behind a pulse voltage which drives the ferroelectric liquid crystal actually to obtain opposite-polarity charges which are equal to the DC component of a pulse voltage to be applied as a driving voltage signal which cancel a one-way DC component, and the signal which is much short in time than said voltage signal is used as units. There are two opposite-polarity ON and OFF units. Consequently, the driving voltage signal which reduces the mean value of the amount of charges applied to the ferroelectric liquid crystal within a specific period to zero is obtained and the liquid crystal element never deteriorates owing to the electrochemical reaction of the DC component.

SOLUTION: A steel pointing trowel 1 has a top board portion 2, and right and left leg board portions 3R and 3L extending from right and left sides of the top board portion 2 in a manner downward expanding to the right and left, respectively. The front end of the top board portion 2 has a rectangular recess 2a having a size of 4 mm in depth and 14 mm in width, for build-up welding. The front ends of the right and left leg portions 3R, 3L each form a slanting surface 3a from the front end upper side to a rear lower side at an angle of 40 to 50 degrees with respect to the top board portion 2. When the pointing trowel 1 is lowered, a sealing material has its height restricted by the upper end of the recess 2a, to thereby be spread rightward and leftward.  Then, the sealing material is inward collected by the right and left leg board portions 3R, 3L, and built up so as to have the width and thickness defined by the recess 2a in a manner covering an abutting portion, to thereby form a joint. Thus, the joint can be formed with good workability, leading to improved construction efficiency.

Filed: 1992-04-21
Abstract: PURPOSE:To prevent the scattering of toner on a carrier by maintaining the potential by electrification of the carrier and the electrostatically sticking force of the toner, when the carrier is skipped or returned at high speed. CONSTITUTION:In the belt transfer of the first color, the charge of a belt 10 is removed by an earth roller 20 on the upstream side of a belt transfer part 23, and a bias potential is applied to belt transfer bias rollers 17A and 17b, to perform a transfer. After the transfer is completed, the leading edge part of an image is quickly returned up to the belt transfer part 23. At this time, the earth rollers 20 and 21 are changed over into a floating state (the potential by the electrification is maintained). Thus, after the quick return, the sticking force of the belt and a toner layer is maintained, as well, and the scattering of the toner is reduced. In the next belt transfer, the earth rollers 20 and 21 are dropped in an earth, again, and influence on a belt transfer potential is prevented.

Title: COPPER MATERIAL FOR NEGATIVE ELECTRODE CURRENT COLLECTOR OF Li ION BATTERY AND Li ION BATTERY
Inventor: KODAIRA MUNEO
IPC: H01M10/0566
Filed: 1999-04-08
Abstract: PROBLEM TO BE SOLVED: To improve adhesion to a carbon layer, and to increase an output current per unit weight by forming a plurality of through holes having an inner peripheral surface having a prescribed surface area in copper foil. SOLUTION: A shape of a through hole is desirably a circular shape and a quadrangular shape such as a square shape and a rectangular shape. When forming the through hole is a circular shape, the inside diameter is set less than 2 times a thickness of copper foil, and in a quadrangular shape, the length is desirably set less than 2 times a thickness of the copper foil in either side. As a result, the area of the through hole in both surfaces of the copper foil becomes smaller than the surface area of an inner peripheral surface of the through hole, so that the total surface area as the whole copper foil becomes larger than a shape of not forming the through hole.  Since the copper foil is required to have prescribed strength for preventing rupture when applying carbon, a pitch for forming the through hole is desirably set to 2 to 10 times the length of an inside diameter or one side of a circular or square through hole.

Abstract: PURPOSE:To obtain an EC element having a large density change without the exfoliation of an iridium oxide film by forming said film as an oxidation coloring layer by a specific anodic oxidation method. CONSTITUTION:The anodic oxidation of the metallic iridium film is executed by continuously impressing sweep potential first at a small amplitude then at a large amplitude at the time of sweeping the triangular wave potential to a glass cell to form the iridium oxide film 1 to be used as the oxidation coloring layer of the EC element. The magnitude of the amplitude of the sweep potential varies with the number of sweeping times as the small amplitude to be impressed first and is usually preferably -0.6-1.5V, more preferably -0.15-1.15V sweep potential width. The range except said range is the cause for the exfoliation of the film. The sweep potential width of the AC potential of the large amplitude to be impressed thereafter varies with the number of sweeping times and is preferably -1.5-2.0V, more preferably -1.0-1.5V. The exfoliation arises in ranges except said range.
