Title: Flow rate-measuring apparatus
Inventor: OCHI KENZO
IPC: G01F1/66
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To suppress jittering at a zero cross point where a propagation time of ultrasonic waves is measured and improve a measurement accuracy by driving ultrasonic vibrators set opposite to each other to an upstream and a downstream sides of a channel with a synthesized driving frequency of a plurality of frequencies. SOLUTION: Ultrasonic vibrators 3 and 4 are set opposite to each other to an upstream and a downstream sides of a part 2 of a fluid channel 1 where a fluid flows. A flow direction 6 is made to cross a propagation direction 7 of ultrasonic waves. A flow velocity operated from a propagation time between the ultrasonic vibrator 3 at the upstream side and the ultrasonic vibrator 4 at the downstream side is multiplied by an area (width W× height H) of the channel 1, thereby obtaining a flow rate. At this time, various unnecessary vibration components included in a received waveform, that is, jitter components greatly affect a zero cross point where the propagation time is measured. Therefore, the ultrasonic vibrators are driven not only with a principal frequency, but with a sub frequency component of various frequencies included.  Since a vibration or phase of the sub frequency component is changed, the unnecessary vibration components can be reduced. The jitter components when the time is measured are reduced, so that the zero cross point is stabilized.

Title: Method and apparatus for testing response of stress wave sensor
Inventor: TOREBOO JIEEMUSU HORUROIDO
IPC: G01R29/22
Filed: 1990-04-21
Abstract: PURPOSE: To perform response test of a sensor by supplying first and second electric pulses from a pulse circuit to a point between a transducer and an amplifier depending on an input rectangular wave. CONSTITUTION: Response is tested for a sensor 10 comprising a transducer 12 and an amplifier 20 connected in series. During an interval when a rectangular wave is being fed to an input terminal 26, a pulser circuit 24 supplies first and second electric pulses continuously and alternately to an output terminal 60 depending on the input. The circuit 24 supplies a first electric pulse of relatively large amplitude to the sensor 10 at a point between the transducer 12 and the amplifier 20 and generates an additional electric pulse to the transducer 12. Active conditions of the transducer 12 and the amplifier 20 are determined based on the conditions of the amplifier 20 for both pulses. Furthermore, gain of the amplifier 20 is determined based on the output from the amplifier 20 when a second electric pulse of relatively small amplitude is supplied thereto.

Abstract: PURPOSE: To form a sound impurity diffusion layer free of damage and also form an electrode wiring of a high melting point metal or a silicide on the diffused layer thereby to obtain an excellent ohmic contact.  
     CONSTITUTION: A p-type silicone substrate 11 is subjected to an oxidization treatment to form a silicon oxidize film 12 thereon, and further an oxidation-proof film (silicon nitride film) 13 and subjected to a heat oxidation treatment thereby to form a field oxide film 14.

Upon this occasion, in order to prevent the diffused layer 16 from undergoing damages, an oxide film 17 is formed. Then, oxide films 12 and 17 are removed by etching, and a silicon oxide film 18 for a gate oxide film is formed again and holes are formed to evaporate a high-melting point metal or a silicide thereto to form an electrode wiring, which is then subjected to photolithography to form a gate electrode 20 and a source take-out electrode 21.

Title: Lid opening-closing mechanism for rice cooker
Inventor: MURAMATSU KENJI
IPC: B65D43/26
Filed: 1994-05-20
Abstract: PURPOSE:To prevent scattering of water drops adhering to the inside of a lid to the perimeter thereof when the lid is opened by arranging an energy storage means to store energy when the lid body is turned to close and a braking unit to brake the turning of the lid body when the body is turned to open to brake a turning speed of the lid body to open. CONSTITUTION:In the opening of a lid 2B of a cooker, when the end of a retaining piece is pressed to release the engagement of a protrusion with the other end of the retaining piece, an inner lid 2B is turned open by a torque storing the torsion of a torsion coil spring. At this point, the clockwise rotation of a driving gear 5 having a non-circular gear part 5a meshed with a non- circular gear part 4a is transmitted to a worm gear 72B through gears 71 and 72A to turn a worm shaft 64. As a result, a friction plate 65 of a braking unit is expanded so as to be open by a centrifugal force and contacts an internal wall 66b of a braking cup 66 to generate a friction thereby braking the turning of the inner lid 2B. As the inner lid 2B turns exceeding 90 deg., it contacts the rear of a contact member thereby enabling the regulation of the turning thereof.

Abstract: PURPOSE: To prevent occurrence of failures by opening a chopper-shorting means when a main-circuit current exceeds a preset value in the case a motor is controlled, by shorting a chopper and applying a full voltage to the motor.  
     CONSTITUTION: When an advance or backing switch MF or MR is switched, and the conduction rate of a chopper 3 is controlled by applying an accelerator pedal, a charging current is flown into a capacitor C 1 . When the charging current exceeds the Zener voltage value of a Zener diode ZD 2 , the gate of a thyristor S 1  is opened, and a relay coil 4 is energized. Therefore, the chopper 3 is shorted by a switch 4a. When a load current has increased, and the voltage sensed by a sensing resistor R 1  exceeds the preset value of a comparator 8, a thyristor S 2  is turned on by the output signal of the comparator 8, the thyristor S 1  becomes non-conductive, and the contact 4a is forcibly dropped out, thereby the chopper operation is commenced.

Title: Device and method for encoding
Inventor: TAKANO SHUNSUKE
IPC: H04N19/50
Filed: 1995-04-08
Abstract: PURPOSE: To manage image data, which are encoded for the unit of a picture group, within prescribed unit time by forming the image data corresponding to the prescribed unit time for the unit fo prescribed frame groups while adaptively switching the number of picture in the picture group composed of image data corresponding to the transmission rate of input image data. CONSTITUTION: Since the transmission rate is 25 frames/second when the image data depends on a 625/50 system, 25 frames are required for obtaining image data corresponding to one second. Then, a frame processing part 2 alternately dynamically switches the number N of frames in the picture group to 12 and 13 corresponding to a control signal during frame reading. As a result, the image data of 25 frames are formed in just two screen groups and image data for one second can be formed. The respective picture types of the frame are rearranged from a rearranging circuit 7 and send to a codec 4. In this case, it is necessary to turn the final frame of the picture group to a P (inter-frame encoded image) picture for standard.

Title: Method and device for mesuring distance using microwave

Filed: 1991-04-15
Abstract: PURPOSE:To prevent misjudging of distance when using an FM-CW radar method whereby the distance to a relatively nearby target object is detected using microwaves. CONSTITUTION:A transmitted signal f(t) which is frequency modulated by continuous modulation signals having a rectilinear slope of a fixed amplitude is converted into a radio wave through pulse modulation 16 and radiated from an antenna 22, and an input signal including a directly reflected wave (b) from a target 24 is mixed with part of the transmitted signal (a) by a mixer 20, and of intermittently obtainable phase difference signals those which coincide with the timing of only the directly reflected wave (b) are extracted to reproduce 62 beat signals (f) and only the target is judged from the beat signals. Because the beat signals are reproduced by extraction of the input signals only at the timing where the directly reflected wave exists, target signals which do not include multiple reflected waves can be obtained.
