Patent JP-S54156574-A (JP)
Title: Oscilloscope
Inventor: TSUJI SACHIO
IPC: G01R13/26
Filed: 1978-05-30
Abstract: PURPOSE: To enable sharp waveform portions to be distinctly observed by automatically increasing luminance only near the sharp waveform and maintaining the original low luminance at the mild waveform portions.  
     CONSTITUTION: Signal T is applied to a detecting circuit 8 which detects sharp waveform portions, thence the detection signal thereof is supplied to a luminance signal generating circuit 9 which performs luminance signal control after having made waveform processing. The string of the detection signal corresponding to the generation of the sharp waveform is created at the (e) point of the luminance signal generating circuit 9 and the output having the time width determined by the time constants of C 2 , R 2 , R 3  is obtained at the (f) point through transistors TR 7 , TR 8 , the output whereof is then applied to the grid G or cathode K of a Braun tube 4. As a result, the luminance increases automatically in a certain period from the point when the sharp waveform has arrived and therefore observation of the existence of the sharp waveform and the waveform itself may be distinctly accomplished.

Abstract: PURPOSE:To reduce the current consumption at the time of operation of read-out and write by providing an address variation detecting part, and a bidirectional data latching part on an address input line, and a data input/output line, respectively. CONSTITUTION:This circuit is provided with an address variation detecting part 12 for detecting a variation of an address signal inputted to an address line 5, and a bidirectional data latching part 13 for holding temporarily a signal inputted and outputted to and from a data line 6. In this state, during the time when a variation of an address input is not recognized, the address variation detecting part 12 outputs a non-selection signal to all memory selection lines 10a-10n and sets the current consumption of all semiconductor storage elements 1a-1n to a stand-by power source current, and also, applies a latch signal to a bidirectional data latching circuit 13, and holds output data until the next address variation is recognized. In such a way, the current consumption at the time of read-out and write can be reduced.

Inventor: ASHIZAWA TORANOSUKE
IPC: H04R3/00
Filed: 1986-03-24
Abstract: PURPOSE:To surely resume atomization by preventing the adhesion of a liquid droplet to an atomizing surface at the time of the interruption of the atomization, by connecting a liquid supply solenoid valve control circuit to one end of the load of an oscillation circuit through a delay circuit. CONSTITUTION:When a power source is closed, AC voltage is generated in the load to an amplifying circuit and fed back to the input side of the amplifying circuit by a feedback circuit to start oscillation. A piezoelectric vibrator 5 is connected to this feedback circuit and the current flowing through the piezoelectric vibrator 5 becomes max. at the resonance frequency of an ultrasonic atomizer and, therefore, the current fed back by the feedback circuit becomes also max. at the resonance frequency of the ultrasonic atomizer and oscillation continues at the resonance frequency. The AC voltage generated in the load is also inputted to a delay circuit and further inputted to a solenoid control circuit after the elapse of a definite time determined by the constant of the delay circuit and a solenoid valve is operated to supply a liquid and the adhesion of a liquid droplet is prevented by this time shift.

Title: Motor drive circuit
Inventor: YAMADA TOMOHIKO
IPC: H02P7/03
Filed: 1985-03-29
Abstract: PURPOSE:To control the voltage between the terminals of a DC motor to become constant by detecting the voltage between the terminals according to the polarity-changing operation of the voltage. CONSTITUTION:A voltage VM between the terminals of a motor 22 is detected, negatively fed back to a drive voltage generator 23 to control the level of the drive voltage Vs of the motor 22 to always hold the voltage VM at constant level. In this case, the voltage VM is detected through an electronic changing switch 24 which uses C-MOS analog switch, and the contacts 241, 242 of the switch 24 are switched in cooperation with the switching of ON and OFF of transistors Q21-Q24. Thus, the polarity of the detected output of the voltage VM is set at one polarity to be fed back as a voltage control, and the input polarity of the detected output for a differential amplifier 25 is always maintained constant.

Title: Programming system for interactive numerical controller
Inventor: FUJITA NAOKI
IPC: G05B19/4093
Filed: 1990-03-15
Abstract: PURPOSE:To improve the programming task efficiency by defining the shape of parts a primary working area and then a secondary working area and outputting the NC data after dividing after dividing this data into the primary and secondary working data. CONSTITUTION:An operator defines the shapes of a material and a parts and decides whether a process includes the secondary working or only the primary working with no secondary one. If the secondary working is included in the process, the cutting area of the primary working is defined in an exactly same way as an ordinary double skindl lathe. In the secondary working, the shapes of the material and the parts are plotted after inversion. Then the cutting area of the secondary working is defined in a similar image as the primary working. In such a way, a programming device of an interactive numerical controller outputs the NC data after dividing automatically the data into the primary and secondary working data. Thus it is possible to improve the deterioration of efficiency due to a fact that the NC data are programmed separately from each other despite the final same shape of the parts.

Abstract: PROBLEM TO BE SOLVED: To obtain a method of driving that enables miniaturization of a force motor and a force motor that can be miniaturized. SOLUTION: A force motor having a housing 11, a pair of electromagnetic coils 12, permanent magnets 13, and stators 14, an armature 18, and a spring 21 that supports the armature, is driven by attracting and displacing the armature 8 by controlling the current applied to the electromagnetic coils 12, wherein the gap G at the displacement edge of the armature 18 is made extremely small to allow nonlinear increase of the attractive force, while the current applied to the electromagnetic coils 12 at the displacement edge of the armature 18 of the force motor 1 is adjusted so that the magnetic flux density is saturated by a magnetic circuit to compensate the nonlinear increase of the attracting force at the displacement edge of the armature with the nonlinear decrease of the attracting force caused by the saturation of the magnetic flux density.  As a consequence, linearity of the attracting force with respect to the applied current is maintained.

Title: Three phase transformer with stabilized windings
Inventor: SAKAKURA OSAMU
IPC: H01F30/12
Filed: 1984-04-05
Abstract: PURPOSE:To reduce an interwinding insulation size by earthing a wire terminal of stabilized winding facing a wire terminal of a low voltage winding in the phase where the winding direction of the low voltage winding is reverse. CONSTITUTION:Although the connection of each phase and the winding direction of each stabilized winding I -3, II-3 and III-3 is the same as conventional ones, there is a special feature in earthing the terminal T8. According to this three phase transformer with stabilized windings, the voltage which is generated between the terminal (u) located in the upperpart of the low voltage winding I -2 and the stabilized winding I -3 and the terminal T1 is 1.5e-N3/N2.e in the induction voltage proof test for the low voltage winding of the phase I , and the voltage generated between the terminal (v) and the terminal T8 is 1.5e in the induction test for the low voltage winding II-2 of the phase II, and also the voltage generated between the terminal (w) and the T8 is 1.5e in the induction test for the phase III. As mentioned above, all voltages show value lower than the voltage obtained in the AC tests for the wire terminal winding 2. Consequently, the insulation distance between the low voltage 2 and stabilized winding 3 can be shortened as compared with the conventional. The summed length of the connecting leads 5, 6, 7, of the stabilized winding 3 is not changed and the facilitation of the connection between each phase is not changed.
