Title: Speed detector
Inventor: NAKAMURA TSUNEO
IPC: G01S15/60
Filed: 1995-05-31
Abstract: PURPOSE: To extract a frequency shifted by a Doppler effect by modulating received signals into an intermediate frequency by using the frequencies of a reference transmission oscillator and a reference reception oscillator and finding the frequency difference between the intermediate frequency and the output of the reference reception oscillator. CONSTITUTION: The output signal of a reference transmission oscillator 1 is converted into ultrasonic signals by means of a transmitter-receiver 4 after passing through a transmission amplifier circuit 2 and a transmission-reception switching circuit 3 and radiated, for example, into water and reflected waves from an underwater object are converted into electric signals by means of the transmitter-receiver 4, amplified by a certain degree by means of a preamplifier 5 after passing through the circuit 3, and supplied to a second mixing circuit 8. The output signal of a reference reception oscillator 6 is mixed with the output signal of the oscillator 1 at a first mixing circuit 7 and supplied to the circuit 8.  Then an intermediate frequency is generated by mixing the outputs of the circuits 5 and 7 and the intermediate frequency is mixed with the output of the oscillator 6 at a third mixing circuit 10. Thereafter, a Doppler-shifted frequency is extracted from the output of the circuit 10.

Title: Pre-amplifier for television camera
Inventor: OZAWA NAOKI
IPC: H04N5/14
Filed: 1977-12-26
Abstract: PURPOSE: To secure the constant output voltage for the pre-amplifier by detecting the output voltage of the flyback time for the output of the pre-amplifier or the video process circuit and having the negative feed back of the difference power between the detection voltage and the reference voltage to the pre-amplifier via the high gain differential amplifier.  
     CONSTITUTION: The output signal of pickup tube 1 is led to video process circuit 8 via pre-amplifier 6 and then delivered 4. In this case, sampling 9 is given to the flyback time output voltage of the output of amplifier 6 or circuit 8 to have a comparison with the reference voltage given from reference voltage generator circuit 11. And the difference voltage is fed back negatively to the input side of amplifier 6 via high gain differential amplifier 12. In this way, the pre-amplifier output voltage can be kept constant accurately within the effective temperature range of the TV camera.

Title: Waveform shaping circuit
Inventor: SUTEFUAN TORAUBU
IPC: H03B1/04
Filed: 1980-11-05
Abstract: PURPOSE: To convert a triangle wave signal into a sinusoidal wave signal simply, by using nonlinear characteristics of a transistor differential amplifier.  
     CONSTITUTION: An input signal is fed to terminals 15, 17. This signal is differentially input to differential amplifiers 11∼13. The differential amplifier 11 has an amplifying characteristics symmetrical to a negative input signal. The amplifying characteristics of a differential amplifier 12 are shifted toward positive direction and those of the differential amplifier 13 are shifted toward the negative direction. The triangle wave signal input is converted into a sinusoidal wave with the nonlinearity of the differential amplifiers 11∼13. Especially, in the peak of a triangle wave, the conversion to a sinusoidal wave is made in excellent manner without polygonal lines through the characteristics of the differential amplifiers shifted toward positive and negative direction.

Title: Image recording device
Inventor: FUJITA AKIHIRO
IPC: B65H23/34
Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To effectively correct a curl of recording paper by bringing a correcting assistant member in contact with recording paper wrapped around a curl correcting member in the direction of enlarging the wrapping quantity. SOLUTION: While adding tension due to friction force between a recording paper roll R and the bottom part of a holder part and the dead weight of the recording paper roll R to recording paper P, the outer circumferential face of a decurl roller 33 is slidably contacted with the outer face, and it is reversely rotated and the paper is transported. At this time, because the outer circumferential face of an assistant roller 41 is slidably contacted with the inner face of the recording paper P, the conveying route is approached to a pickup roller 23, the recording paper P is largely reversely rotated more than the case of no assistant roller 41, the wrapping quantity to the decurl roller 33 is enlarged, and the wrapping angle θis minified.  Consequently, a curl of the recording paper P is more effectively corrected compared with the case only by the decurl roller 33, and the paper can be conveyed to an image recording part without generating paper passing jam due to curl.

Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To improve the electrostatic destruction strength of NC(non-connection) pins in a logic LSI which adopts a master slice system. SOLUTION: In a CMOS gate array, a bonding pad corresponding to a signal input cell and a bonding pad corresponding to a power input cell are constituted of the conductive layers of three layers. A bonding pad corresponding to an I/O cell 3c, which is not used is constituted only of conductive layer 70b of the highest layer. Thus, a film thickness (11) at a lower part in a bonding pad (NC pad) BP, corresponding to an I/O cell 3c which is not used, is thicker than those of the signal bonding pad BP and the power bonding pad BP, and a distance with a semiconductor substrate 1 becomes larger.
