Title: Signal detection circuit
Inventor: TOUFUKU ISAO
IPC: H04N5/335
Filed: 1983-09-30
Abstract: PURPOSE:To obtain the titled circuit without time delay, performing high speed action having low noises by a method wherein the input signal of a differential amplifier is selected by switching by means of an analog switch and a sample hold circuit in such a manner that the output of the amplifier is not saturated. CONSTITUTION:The input signal to the negative input terminal of the differential amplifier AMP1 is enabled to be switched by means of the sample hold circuit 15 and the analog switch ASW. The amplifier output is prevented from being saturated outside a dynamic range by enabling the application of the same input waveform on the positive and negative input terminals of the AMP on appearance of the waveform of an injection pulse phiinj in the source floor output of an FET Q1. On the other hand, the signal output from a CID sensor obtains an amplified signal by switching the ASW to input the reset level to the negative input terminal of the AMP under sample holding. This manner enables the high speed action of the differential amplifier by enabling the input signal to alwyas come in the dynamic range of the amplifier.

Title: Manufacture of semiconductor device
Inventor: KATO TAKASHI
IPC: H01L21/28
Filed: 1985-08-20
Abstract: PURPOSE:To prevent oxidation by conducting annealing in an atmosphere in which hydrogen and oxygen remaining in an inert gas are brought to a specific partial pressure ratio. CONSTITUTION:A film 2 made of a substance such as Zr is applied onto an Si substrate 1, and a coating board 3 is formed onto the film 2 through an interstice 4. An inert gas containing hydrogen in used under the state, and the partial pressure ratio of hydrogen to oxygen remaining in the gas is elevated to 100 or more and the whole is annealed and treated. Oxygen in the gas has low partial pressure and also has a small diffusion coefficient, thus permeating only into regions A in the interstice 4. Since hydrogen having high partial pressure also has a large diffusion coefficient, on the other hand, it can reach a region B. Consequently, the partial pressure ratio of hydrogen to oxygen in the vicinity of the surface of the film 2 can be brought to 100 or more. Accordingly, the oxidation of the film 2 can be prevented, and oxygen can be discharged from the interface between the film 1 and the film 2, thus improving the quality of the films and productive efficiency.

CONSTITUTION:When a slide door 1 is moved to an opening direction A via a support roller 7 and a guide roller 10, parallel linkage 15 is displaced to the counter-A direction side, and engagement between a gear 21 of a link 12 and a gear 20 of the support roller 7 comes off, while braking by a compression spring 23 of a rotating roller 17 is released. And, when the slide door 1 is moved to the opposite side, the parallel linkage 15 is once returned to the neutral position, so that these gears 20 and 21 are engaged with each other, while the rotating roller 17 is pressed to a rocking bracket 16 by dint of the compression spring 23, thus it is braked. On the other hand, when the slide door 1 is moved again, the slide door is forcedly pushed to the moving direction, and the parallel linkage 15 is displaced to the counter-moving direction side.

Title: Ciphering/deciphering equipment
Inventor: SENOO MASAYUKI
IPC: H04L9/36
Filed: 1986-08-02
Abstract: PURPOSE:To easily detect a transmission error by detecting the randomness of a fixed number of continuous signals '1' when these signals '1' are ciphered and transmitted and then deciphered. CONSTITUTION:The continuous '1' signals 13 of a fixed bit are ciphered by a deciphering circuit 11 and transmitted after an initial value transmitting part 12 of a ciphering device 1 transmitted the initial value that decides a cipher system, i.e., the random numbers for ciphering. While a counter 23 counts and confirms the continuous '1' signals of a fixed bit by the working of a deciphering circuit 21 after said initial value is received by an initial value receiving part 22 set at the reception side. Therefore the ciphered signals of said continuous '1' signals are never deciphered into the correct original '1' signals even though they are correctly transmitted to the reception side as long as the initial value sent from the device 1 has an error on a transmission line. Thus it is possible to easily recognize a transmission error of the initial value at the reception side from a deciphering signal.

Title: Pll circuit and frequency comparator circuit
Inventor: MASUDA NOBORU
IPC: H03L7/06
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To provide a PLL circuit with which phase difference or jitter can be reduced and a clock signal having high phase accuracy can be provided. SOLUTION: When phase difference is generated between both a reference signal 150 and a feedback signal 160, a phase comparator circuit 101 sends the compared result (showing which signal is advanced) to a control pulse generating circuit 154. Then, the circuit 154 changes the charge contents of a charge pump 105 and each time the same compared result is provided, a counter circuit 102 increases the count value. When the compared result is changed, the charge contents are changed just for the value in proportion to the count value corresponding to the changed state. When frequency difference is generated between both signals, this frequency comparator circuit 103 sends the compared result to the control pulse generating circuit 154 and the charge contents are changed in spite of the phase compared result and the count value.  Thus, a voltage controlled oscillator 107 is controlled by the output of a waveform dull circuit 106 for which the output of the charge pump 105 and the compared result of the phase comparator circuit 101 are made dull.

Abstract: PURPOSE:To stabilize a quality by improving working efficiency in kneading, by a method wherein a compounding material for a molding material is extruded while feeding quantitatively and continuously to a kneading machine and kneading and when the molding material to be extruded is measured and a measured value attains a fixed value, the same is loaded into a roll kneading machine for roll kneading. CONSTITUTION:A molding material prekneaded by a continuous kneading machine 1 is extruded continuously to a measuring machine 9 through an outlet part of the continuously kneading machine 1. The measuring machine 9 is formed of a hopper, damper and measuring device provided with a load cell and the molding material to be extruded through the continuous kneading machine 1 is measured automatically by the measuring machine 9. At a point of time when the molding material attains to a weight per one batch, the molding material is taken out of the measuring machine 9, loaded into a roll kneading machine 2 and kneading is performed by a roll kneading machine 2. Workability in kneading can be improved by setting up a kneading and extruding rate of the continuous kneading machine 1 so that hours required for kneading one batch with the roll kneading machine 2 become almost identical with those required for extruding the molding material equivalent to the weight per one batch from the continuous kneading machine 1 like this.

Title: Method and apparatus for transfer of digital data packet on radio channel
Inventor: BURUUSU TEII TATSUCHI
IPC: H04B7/26
Filed: 1993-06-30
Abstract: PURPOSE: To enable controlling at simple and effective transfer output level for controlling the transfer of digital data packet from a radio data communication system by transferring the packet during a time interval, only when a prescribed average output level is not exceeded. CONSTITUTION: For the output level of an ordinary information packet to be transferred from a station A to stations B-D, the transfer from the station A through the station B requires a comparatively high output level because of electromagnetically absorptive obstacle 16. Further, in the case of a transfer from the station A through the comparatively closer station C, a comparatively low output level is enough and in the case of transfer from the station A through the station D, an intermediate output level is required. Since the minimum output required for efficient packet reception is used for this connection, the advantage for reducing average interference rather than using the fixed output level intending a maximum distance 'under the worst conditions' can be provided. Moreover, at the station for supplying power from a power source, a battery output can be economized.
