Title: Main spindle control device for lathe tuning machine
Inventor: OIDA KAZUO
IPC: B23Q15/00
Filed: 1985-01-18
Abstract: PURPOSE:To prevent a decrease of accuracy due to a gear clutch and save energy, by switching a D/A converted output of an S code and a normal and a reverse instruction signal at normal time with speed instruction voltage and a position feedback pulse signal at code machining time. CONSTITUTION:A control device, instructing a normal main spindle function by a central processing unit 3 and inverting speed instruction voltage by a reversible switch 5 to the polarity of positive or negative voltage to be input to a main spindle servoamplifier 6, controls a motor 2 to a fixed speed. Here the speed of a main spindle 1 used for every rotation feed, thread cutting, etc. is input to a pulse distribution controller 9. While the device, when it is con trolled as a C shaft, transmits a pulse to a deviation counter and D/A converter part 10 to be input to the amplifier 6 and detects by an encoder 11 a position of the main spindle 1 to be fed back to the deviation counter and D/A converter part 10. Here switches (a), (b) are switched by an M code programmed for switching a Z mode, but an auxiliary function switching part 12, decoding also the normal and reverse M code of the main spindle 1, gives an instruction to the reversible switch 5 to switch it.

Filed: 1977-12-21
Abstract: PURPOSE: To discriminate the polarity of the surface potential, by converting the surface potential of the surface being measured into alternating current and measuring, with a simple means to apply bias potential to chopper blades.  
     CONSTITUTION: Rotary chopper blades 1 are located between the surface being measured 2 and a measuring electrode 3. A means 8 to apply specified bias voltage to the chopper blades 1, a means 5 to rectify the induced voltage in the measuring electrode 3, and an arithmetic circuit to subtract the voltage equivalent to the output of the bias voltage from the obtained rectified voltage are provided to set up the constitution. High impedance, small signal induced into the measuring electrode 3 is amplified by an amplifier 16, and the output thereof is rectified by a diode 5, and is smoothed by an amplifier. It is then added with the inverted voltage of the output equivalent potential at terminal 7 of bias potential applied to terminal 11 at an operational amplifier 12, so that the potential 0 at the time of measuring potential = 0 will appear at output terminal 14. Thus, whether the surface potential is positive or negative may be discriminated.

Title: Industrial robot device
Inventor: YAMADA KAZUMI
IPC: B65G47/80
Filed: 1988-01-18
Abstract: PURPOSE:To enhance the shifting/mounting efficiency of an industrial robot device by arranging a projection on the back surface of a rotary plate and, allowing this projection to freely touch a limit switch attached to a base table so that a pallet can be taken out by a hand from a pallet supply part, every time the rotary plate reaches its positive/reverse rotation-end. CONSTITUTION:When a hand is rotated in the positive direction via a revolving shaft, a rotary plate 12 situated at the base part of the revolving shaft is rotated similarly. When the plate 12 rotates to the position at which the hand can take out a pallet from a pallet supplying part that is behind the pallet standard position, a projection 12A on the back surface of the rotary plate 12 touches a limit switch 13A attached to the base table in order to stop the rotary plate 12. Next, the hand holds the pallet and rotates in the reverse direction to put the pallet on a palletizing position on one side. Similarly, when the hand is rotated in the reverse direction, it holds a pallet at its another rotation-end and rotates in the positive direction to put the pallet on a palletizing position on the other side. With this contrivance, a length of the shifting/mounting route for the hand to reach the palletizing position can be shortened, thereby enhancing the pallet-shifting/mounting-efficiency.

Title: Image display apparatus and method of displaying images in it
Inventor: OZAWA RIYUUJI
IPC: H01J29/18
Filed: 1982-01-20
Abstract: PURPOSE:To obtain a clear static image having no flickerings by taking advantage of the hysteresis effect which appears in the emissional strength which is dependent upon an electron-accelerating voltage, which is observed in making a phosphor screen emit light by radiating electron rays on the screen. CONSTITUTION:Part of a fluorescent film 11 irradiated by electron rays discharged from the second electron gun 13, owing to the hysteresis characteristic of the fluorescent film 11, comes to emit light constantly due to electron rays discharged from the first electron gun 12. By modulating the electron rays discharged from the second gun 13 according to the input signal after they are excellently focused, and scanning the modulated electron rays over the fluorescent film 11 for an instant, a bright static image corresponding to the modulating signal is constantly pictured on the fluorescent film 11 by means of the first electron gun 12. In such a static image, since it emits light constantly, no flickerings which are often observed in an image observed by repeatedly carrying out scannings in the usual cathode-ray tube, are observed. In addition, the static image can be maintained on the film 11 until an eliminating operation is applied.

IPC: A45D19/00
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To provide a method of applying a hair-dye for applying a hair-dye quickly and evenly to the hair with simple motions. SOLUTION: First, a parting line A is made in the hair, and bristles 14 holding a hair-dye are applied to the hair so that the longitudinal direction of the bristle line is along the hair stream in the parting line A. Under that condition, the bristles 14 are moved forward and backward crossing the hair stream so that the hair-dye is applied to the hair in almost the same width as of the longitudinal direction of the bristle line. Then another parting line is made in a position apart from the area of the hair where the hair-dye has been already applied, and the same series of hair-dye application processes are made so that the hair-dye is applied to the hair only in the width of the longitudinal direction of the bristle line without gap with the area where the hair-dye has been previously applied. Thereafter, the same processes are repeated.

An operation means 23 is made to calculate a maximum steering angle allowed at each time point according to each condition set with the setting means 22. When a specific steering angle is reached, a second comparison means 28 discriminates the agreement of the angles and shuts off a signal to a solenoid valve 26 by means of a switch part 27 to restrict the steering action of the front wheel.

Abstract: PURPOSE:To prevent the abnormal operation owing to a positive feedback by connecting diodes between the output terminals of playback amplifiers and sound recording amplifiers having complementary output stages for each of right and left channels and grounding the other terminal of the diodes with a switch interlocked to a sound recording-playback changeover switch. CONSTITUTION:A switch 1 interlocked to a sound recording-playback changeover switch is on the playback side P (sound recording side R) and the emitter mid- point of a transistor constituting the complementary output stage of sound recording amplifiers 17, 18 for right and left channels is connected to the ground via diodes 25, 26 in the stage of playback. The mid-point of the complementary output stage is thus biased to the forward voltage of the diodes 25, 26, resulting in the decreased amplification factor of sound recording amplifiers 17, 18. Diodes 23, 24 are kept connected between the outputs of playback amplifiers 15, 16 of the right and left channels in this stage, but the outputs of the amplifiers 15, 16 are lower than the forward voltage of the diodes 23, 24 are therefore said amplifiers make normal amplification operation to amplify the playback signals from right and left playback input terminals (a), (b) and to output the same to playback output terminals (e), (f).

Abstract: PURPOSE:To obtain a magenta toner for electrophotography controlling a hue and having a fine color and satisfactory weather resistance by adding an anthraquinone dye to a rhodamine dye belonging to C.I. Solvent Red 49. CONSTITUTION:A compd. having a structure represented by the formula as a rhodamine dye belonging to C.I.
