Title: Mobile communication equipment
Inventor: TERAUCHI TORU
IPC: G10L19/00
Filed: 1996-03-07
Abstract: PURPOSE: To prevent the transmission of an unpleasant voice signal by providing the output of a signal whose voice power is equivalent to zero when a digital voice signal from an A/D converter is less than a prescribed value so as to discriminate a noise level. CONSTITUTION: A voice is given to a microphone 1 at a transmission station side, and an analog signal is converted into a digital signal by an A/D converter section 2. The voice framed power of the converted voice signal is calculated by a power calculation section 12a in a voice power calculation section 12 by, e.g. selfcorrelation calculation or the like. A noise level comparator section 13 compares the calculated voice frame power with a threshold level prepared in advance and when the power is less than the threshold level, it is discriminated to be a noise level. Furthermore, when the power is equal to or more than the threshold level, the digital voice signal is outputted as it is.  On the other hand, a time division multiplex connection timing control section 6 and a control section 7 at a receiver side provide a coded digital voice signal to a digital voice signal processing section 5, where the signal is decoded and the result is given to a D/A converter 4 and the converted analog signal is outputted from a speaker 3.

Title: Ignition timing controlling device for internal-combustion engine
Inventor: TAKEUCHI TOSHIO
IPC: F02P5/155
Filed: 1984-03-16
Abstract: PURPOSE:To improve starting properties and stabilize an operating condition by automatically advancing the angle of lead to increase ignition timing, and sufficiently burning and discharging a fuel-air mixture, when the engine temperature or the rotation of engine is low on starting. CONSTITUTION:A starter motor 19 rotates a crank shaft, and an AC current is generated from a charging coil, to charge a capacitor 5 on an ignition circuit A. At the same time, a pulser coil 2 generates pulses periodically, to send an ignition signal from a signal feeding circuit B to the gate of a thyristor 6. Thereby, an electric charge in the capacitor 5 is discharged into the primary coil 3a of an ignition coil 3, a high voltage is induced in the secondary coil 3b, and an ignition spark is generated on an ignition plug 7. At the start of an engine, a base current flows in the NPN transistor 17 of a motor operation detecting circuit C and the circuit C is conducting. Therefore, the electric potential at the base of the transistor 15 of a wave form shaping circuit 11 is at an L level, causing a base current to flow and the circuit 11 conducts. Accordingly, the generation of the ignition signal is made earlier, advancing the ignition point to the angle of lead position right before the top dead center.

IPC: F23D14/58
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To restrict occurrence of not-yet ignited substances and improve a combustion performance by a method wherein a nozzle pattern of a burner is improved.

Title: Toner image transfer device
Inventor: YOSHINO NAOTO
IPC: G03G15/16
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To prevent excess toner from sticking to transfer rolls. SOLUTION: The transfer rolls 50, 51, and 52 independently supported by bearings 50b, 51b, and 52b, respectively, are arranged in the direction of the width of a photoreceptor 1. A bias controller 6 separately applies voltages to the transfer rolls 50-52 via the bearings 50b-52b. In the case of such a small- size recording paper as passing only beneath the transfer roll 51, voltages having opposite polarity to that of a voltage which is applied to the transfer roll 51 are applied to the transfer rolls 50 and 52. As a result, electric fields which do not allow toner to move from the photoreceptor 1 are generated between the photoreceptor 1 and the transfer rolls 50 and 52. Further, the device can cope with various sizes of recording paper by reducing the sizes of the transfer rolls 50 and 52, other than the transfer roll 51 situated in the middle, and by increasing them in number.

Title: Waveguide type optic-acoustic spectrum analyzer
Inventor: KITANO TOSHIHIKO
IPC: G02B6/12
Filed: 1988-03-03
Abstract: PURPOSE:To enable the narrowing of the minimum detectable pulse width of a spectrum analyzer sufficiently without degrading resolutions, by arranging a plurality of elastic surface wave electrodes as light deflection means for generating elastic surface waves at the center of a parallel light beam. CONSTITUTION:A parallel light beam converted to a parallel light with a first flat lens 4 is deflected by elastic surface waves 11-13 radiated from three electrodes 8-10 for generating elastic surface waves arranged at nearly equal intervals within a light beam and then, condensed with a second flat lens 6 to reach a photo detector 7. The electrodes 8-10 for generating elastic surface waves are so arranged that a layout interval l is equal to roughly one-third of a parallel light beam width W. In other words, elastic surface waves radiated from the different electrodes 8-10 exist at an interval of propagation length W/3 without overlapping one another within the parallel beam. Thus, the light beam deflected by the elastic surface waves is given a width W and condensed with a lens 6. This enables reduction of the minimum detectable range to one- third without degrading the frequency resolution at the arrival at the photo detector 7.

IPC: B23K9/26
Filed: 1980-04-14
Abstract: PURPOSE: To improve the welding efficiency without stopping the welding work, by providing a plural number of nozzles for supplying gaseous carbon dioxide and their cleaning member so that, while one nozzle is cleaned, the gaseous carbon  dioxide is supplied from the other nozzle.  
     CONSTITUTION: When molten particles 8 scattered during the course of welding work are melt-stuck to the inner wall of supply nozzle 6 and the supply of gaseous carbon oxide 7 is impeded, cleaning member 11 of the other supply nozzle 10 is started to work and molten particles 8 are removed by means of ring 11a. Thereafter, the other supply nozzle 10 is also operated and gaseous carbon dioxide 7 is supplied from both nozzles 6 and 10. Moreover, almost at the same time with this operation, melt-stuck particles 8 are pushed to the outside of nozzle 6 by means of ring 9a by operating cleaning component 9 and thus said particles 8 are removed. After the particles are removed, the supply of gaseous carbon dioxide from one supply nozzle 6 is stopped, and gaseous carbon dioxide 7 is supplied through another supply nozzle 10 only. Thus the welding work can be made continuously.

Abstract: PROBLEM TO BE SOLVED: To avoid metallic contact of a rotor and a stator by inserting a nonmetallic different kind substance having an inside diameter smaller than a stator inside diameter opposed to the outermost diameter of a vortex flow stage pump rotor into the staror, and minimizing a clearance with the rotor. SOLUTION: A rotor 1 having a multistage vortex flow pump stage 4b and a centrifugal pump stage 4a having an open-shaped retreat blade, is pressed in and fastened to the upper side of a shaft by being supported by rolling bearings 7a and 7b.

Abstract: PURPOSE: To automatically stop the oil discharge from an oil-chamber when a liquid is not charged into an oil-separation chamber by a method wherein the opening of oil-return pipe which discharges separated oil from the oil-chamber is placed higher than the liquid level of stationary liquid condition.  
     CONSTITUTION: The oil separator 2 consists of a cylindrical oil-separating chamber 9 and an oil-chamber 10 surrounding the chamber 9. Both chambers 9, 10 are connected through a filter-plate 13 at the bottom 9a of a housing 9'. To the side wall of the housing 9', a liquid-inlet pipe 11 is connected in tangent direction. Liquid outlet pipe 12 is brazed to a top lid 9b of the housing 9'.
