Title: Power unit
Inventor: KAKIMOTO TOSHIAKI
IPC: H02J1/00
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To prevent the breakage of a load element by an abrupt voltage rise or an abrupt current increase, by providing a circuit in which a switch, resistor, and the load element are connected in series with a DC power source and a capacitor is connected in parallel with the load element. SOLUTION: A power unit 1 is provided with a circuit in which a switch 12, a resistor 13, and a load element 14 are connected in series with a DC power source 11, and a capacitor 15 is connected in parallel with the load element 14. Therefore, when the switch 12 is closed, a transient current (charging current to the capacitor 15) flows and the voltage at both terminals of the capacitor 15 becomes 0 V. As the capacitor 15 is charged thereafter, the transient current gradually decreases. At the same time, the voltage at both terminals of the capacitor 15 gradually rises. Thus, an abrupt voltage rise is suppressed. Since the abrupt voltage rise is suppressed, an abrupt current increase is also suppressed.

Title: Acceleration sensor
Inventor: ASANO SHOGO
IPC: G01P15/09
Filed: 1990-05-23
Abstract: PURPOSE:To shield external noise such as an electromagnetic wave by electrically insulating both positive and negative electrodes of a piezoelectric element from a base table and covering the entire surfaces of the piezoelectric element and a printed circuit board part with a metal case. CONSTITUTION:The acceleration generated by the running of a car is transmitted to a vibration plate 5 through a housing 67, a base table 53 and a sub-base table 55 to impart bending to the vibration table 51. Since the bending of the vibration plate alternately imparts tensile force and compression force to piezoelectric ceramic elements 60, 61, charge is generated in the elements 60, 61. This charge is converted to voltage by a printed circuit board 62 and sensor output is obtained. The vibration plate 51 is mounted in a structure electrically insulated from the base table 53 through the sub-base plate 55 and the elements 60, 61 are electrically insulated from the base table 53 and, further, the vibration plate 51 and the board 61 are shielded by a metal shielding case 57 and an upper plate 58.

Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To increase the compressibility of image compressed data by dividing image data by wavelet transformation, thinning out the data vertically by divided horizontal high-frequency subbands, and removing redundant components and performing entropy encoding. SOLUTION: When source image data 1058 are supplied, 1st subband separation 1002 performs wavelet transformation to generate 1st wavelet data (intermediate DC component data 1059 and LH-, HL-, and HH-component high-frequency data 1055, 1056, and 1057). Then the intermediate DC component data 1059 are received and 2nd subband separation 1003 performs wavelet transformation to generate 2nd wavelet data (DC component data 1051 and LH-, HL-, and HH-component low-frequency data 1052, 1053, and 1054). Vertical thinning 101 sequentially output data generated by vertically scanning the LH-component low-frequency data 1052 by vertical rasters to generate vertically thinned-out LH-component low-frequency data 151.

Title: Fish detector
Inventor: HONDA KEISUKE
IPC: G01S15/96
Filed: 1988-05-31
Abstract: PURPOSE:To certainly detect moving fishes by detecting a fish group by continuously outputting ultrasonic waves from a transmitting vibrator and detecting the Doppler shift of the received waves. CONSTITUTION:This fish detector is provided with a transmitting vibrator 2 and receiving vibrator 3 and is constituted of a transmitter-receiver 14 equipped with a throwing-in section 1 which can be sunk into sea water with a weight, transmitter 5 which continuously sends output signals of a reference frequency to a transmitting section, and a receiver 8 which separates signals having frequencies other than the reference frequency from the output of the receiving vibrator 3. The transmitter 5 continuously outputs ultrasonic waves of the reference frequency and the receiver 8 continuously detects reflected echoes. Since Doppler shifts are produced in the received waves when fishes approach the throwing-in section 1, presence of the fishes around the section 1 can be detected through a display device 13 or an earphone upon detecting the Doppler shifts. Thus moving fishes can be detected certainly.

Title: Rectifier circuit having high harmonic current offsetting effect
Inventor: INOUE HIROYUKI
IPC: H02M7/12
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To correct the electric current of a power system to which higher harmonic generating equipment, such as the load equipment, etc., having a rectifier circuit is connected by offsetting the harmonic current generated from another higher harmonic generating equipment connected to the power system by causing an input current to have peaks near the zero points of an AC voltage. SOLUTION: When, for example, a 100 V DC is required as the DC voltage outputted from a rectifier circuit, the 100 V DC can be obtained by constituting a both-wave rectifying diode circuit 11 of a total of 320 diodes by connecting 160 diodes in series with each other and another 160 diodes in the form of a ladder in parallel with the 160 series diodes in the opposite direction. Since the DC voltage outputted from the rectifier circuit can be adjusted by changing number of the diodes in the diode circuit 11 in such a way, no transformer is required for adjusting the DC voltage. Since the input current of the circuit 11 has peaks near the zero points of an AC voltage, the higher harmonic current generated from higher harmonic generating equipment, such as another rectifier circuit, etc., can be offset.
