Title: Piezoelectric element drive device
Inventor: ISAKA TAKENOBU
IPC: H04R3/00
Filed: 1980-06-06
Abstract: PURPOSE:To enable to prevent the excessive oscillation of a piezoelectric ceramic due to resonance, by providing a negative feedback circuit adding a counter electromotive force produced through a mechanical displacement of a piezoelectric element to a drive signal after converting it into a damping voltage, and a drive circuit. CONSTITUTION:A drive signal of a drive source 7 is amplified at a DC amplifier 9 via, e.g., an adder 8, and it is applied to a piezoelectric ceramic 2 via a series resistor 10. The piezoelectric ceramic 2 driven with an electric signal produces a counter electromotiveforce between a point (a) and the piezoelectric ceramic 2, and the frequency is at maximum at the resonance frequency of the piezoelectric ceramic. The potential difference across the resistor 10 is inputted to a differential amplifier 11 to output the said counter electromotiveforce only in the inverse phase by exclusing the drive signal, and this output is fed back to an adder 8 via a high pass filter 12, phase adjuster 13 and variable resistor 14. Thus, the excessive oscillation due to resonance phenomenon of the piezoelectric ceramic can be prevented and the damage of the piezoelectric element can be avoided.

Title: Hybrid ic
Inventor: ADACHI YOSHIYUKI
IPC: H01L23/50
Filed: 1994-04-15
Abstract: PURPOSE:To prevent the generation of solder crack due to thermal shock, in the case of electronic circuit board packaging. CONSTITUTION:A plurality of connection terminals 6 are arranged on the single end-surface or both end-surfaces of a ceramic board 5 wherein electronic components like IC's 3 are surface-mounted on the single surface or both of the surfaces. A thermal stress absorbing part 6a is formed in a part of the connection terminal 6. Hence a hybrid IC itself has resistance to solder crack. When electronic components are mounted on a main electronic circuit board and automatically soldered, soldering hand method is made unnecessary, and further solder crack and solder flaw can be prevented, because the thermal stress absorbing parts of the connection terminals absorb the stress caused by thermal expansion and thermal contraction.

Title: Molding of terminal of long molded product
Inventor: TERAMOTO YASUNOBU
IPC: B29C43/02
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of trouble such as warp at a terminal part in the evaluation of heat resistance after molding, by forming a recessed part having the shape corresponding to the surface shape of the terminal part on the side of the rear surface thereof to form a terminal shape almost with the same size in length on the upper surface as on the rear surface. SOLUTION: In a heating process, a terminal part 2 of a long resin is collectively heated to be brought to a molten or softened state. Next, in a press process, the terminal part 2 of the long resin 1 in a heated and softened state is pressed not only to form the upper surface of the terminal part 2 into a predetermined concave shape but also to form a recessed part having the shape corresponding to the surface shape of the terminal part on the rear surface side thereof almost with the same in length on the upper as that on the rear surface side. By this constitution, the residual strains on the upper and rear surfaces of a long resin molded product become almost equal and the residual stresses on the upper and rear surface sides thereof are mutually set off.  As a result, even in the evaluation of heat resistance after molding, trouble such as the warp of the terminal part 2 is not generated and the long resin molded product of good and stable quality can be produced.

Title: Motor overload-preventing device
Inventor: MORISHITA MOTOJI
IPC: H02P29/00
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To prevent overload tripping without stopping an AC motor by starting speed control when the average value of a measurement motor drive current exceeds a preset tolerance. SOLUTION: The motor overload-preventing device is provided with a relay 21, a current transducer 22, an A/D conversion module 23, and a controller 24. When a motor drive current is constantly measured by the current transducer 22 and is outputted as a measurement current. Then, the measurement current is converted to a digital signal by the A/D conversion module 23 and is fed to the controller 24, and is taken in as a current resultant value. However, the controller 24 obtains the average value of the motor drive current at a preset operation period and integrates the motor drive current into a buffering area at each operation period. Then, when a preset tolerance current value is exceeded, a sawtooth drive motor 20 is controlled, thus preventing overload tripping without stopping the AC motor.

Title: Ferroelectric liquid crystal panel
Inventor: INOUE KAZUO
IPC: G02F1/133
Filed: 1990-03-27
Abstract: PURPOSE:To allow the execution of a good gradation display by disposing fine particles smaller than the spacing between substrates between picture elements. CONSTITUTION:The fine particles 10 of Al2O3 having 0.5 mum diameter smaller than the spacing between the substrates 1 and 8 of the ferroelectric liquid crystal panel are sprayed in the parts corresponding to the picture elements between the substrates and further, SiO2 having 2 mum diameter are sprayed as spacers 9. The spacing between the substrates varies with the places where the fine particles 10 exist and the places where the particles do not exit if the fine particles 10 having the diameter smaller than the diameter of the spacing between the substrates are disposed. A difference is, therefore, generated in the response of the liquid crystal molecules. Namely, the parts where the ferroelectric liquid crystal inverts varies with the impressed voltages and, therefore, the good gradation display is obtd. Since the disposition of the fine particles 10 is merely necessitated, there is no need for the intricate production process.

Abstract: PURPOSE:To detect the continuous misfire of a multiple cylinder engine simply and positively. CONSTITUTION:Whether a cylinder is in the misfire state is discriminated on the basis of output rotating speed change in a speed detecting period from the compression top dead center of the concerned cylinder to that of a following cylinder. In the case of judging the misfire state of the concerned cylinder, the output rotating speed change, in each speed detecting period, of each cylinder following the concerned cylinder is detected in succession so as to specify the speed detecting period indicating the specified increase tendency of the output rotating speed for the first time after the above-mentioned misfire judgment. All the cylinders to the concerned cylinder from the cylinder right in front of the normally ignited cylinder corresponding to the specific speed detecting period are then judged to be in the misfire state.
