Title: Pellet arranged state detector
Inventor: MIURA TAKANOBU
IPC: H05K13/08
Filed: 1988-04-20
Abstract: PURPOSE:To certainly perform pattern recognition by displaying the arranged state of pellets in the pellet housing holes of an arranging jig as dark and light patterns on a light diffusion plate. CONSTITUTION:An arranging jig 3 is provided with numerous pellet housing holes 3b for housing pellets 2 on the surface of its plate section 3a at prescribed pitches. The no-pellet housing state, normal pellet housing state, and two-pellet housing state of the arranging jig 3 are respectively shown on an obscured glass plate 5 as dark and light patterns. Since the dark and light patterns on the obscured glass plate 5 are produced by surface light emission, a state where the housing hole 3b is inclined when it is directly viewed by naked eyes or from a TV camera and presence/absence of the pellet 2 is very difficult to be judged because of the margin of the pellet being suspended on the edge of the hole 3b occurs. However, when this device is used, the arranged state of the pellets 2 and positions of the housing holes can be recognized immediately from the images on the glass plate 5 even in such case.

Title: Combined head phone with microphone
Inventor: HIRAYAMA YOSHIHIKO
IPC: H04R1/10
Filed: 1983-06-02
Abstract: PURPOSE:To realize an inexpensive head phone with a microphone by using a dynamic loudspeaker not only as a sound outputting means, but also as a sound inputting means, namely, as a microphone. CONSTITUTION:A dynamic loudspeaker 7 is fixed to a buffle 8 and sounds are discharged from the sound releasing hole of the buffle 8 through a pad 3. The outside air can enter a space formed by a speaker box 2 and buffle 8 by means of a pipe 4 through a sound colector 5. A sound which enters through a notch 9 passes through the pipe 4 and vibrates the air in the speaker box 2. Then the vibrated air moves the diaphragm of the dynamic loudspeaker 7 and the sound is transduced into an electric signal. Since the diaphragm of the loudspeaker 7 is made light and thin, the sounds can be detected over a range from a low to high temperature. Since the transceiver equipped with this loudspeaker 7 does not make transmission and reception simultaneously, the dynamic loudspeaker 7 works as a loudspeaker at the time of transmission and as a microphone at the time of reception.

IPC: G03G9/087
Filed: 1989-04-18
Abstract: PURPOSE:To simplify the production process by implanting and covering a coloring agent for covering resin on the surface of powder particles essentially consisting of a thermoplastic resin. CONSTITUTION:The coloring agent for covering resin is implanted and covered on the surface of the powder particles essentially consisting of the thermoplastic resin. The powder particles essentially consisting of the thermoplastic resin and the coloring agent are mixed and thereafter, the coloring agent is implanted and covered on the surface of the powder particles by mechanical energy for the above-mentioned purpose. Since the need for stages, such as heating and kneading of the resin is eliminated in this way, the cutting, thermal decomposing, oxidizing, etc., of the resin particles are decreased and, therefore, the excellent characteristics, such as thermal characteristics, of the resin are prevented from changing in the production process and the production process is simplified.

Title: Microphone
Inventor: HAYASE TORU
IPC: H04R23/00
Filed: 1989-04-18
Abstract: PURPOSE:To accurately follow sound pressure and to dispense with a special dedicated power source by comprising a diaphragm of a superconducting material, and utilizing a Meissner effect proper to the superconducting material. CONSTITUTION:When the sound pressure from the front plane aperture part 10 of a housing to the front plane part 3 of the diaphragm 2 is increased, the diaphragm 2 oscillates in a direction to be pressed in the direction of a permanent magnet 4. At the oscillating state, a magnetic flux is repulsed by the Meissner effect on the diaphragm 2 since the diaphragm 2 is comprised of the superconducting material, and the magnetic flux is remarkably repulsed from the N-pole of the permanent magnet 4 toward the rear plane part 5 of the diaphragm 2. As a result, the quantity of the magnetic flux that can pass a magnetic flux distribution change detecting coil 7 is decreased in a magnetic distribution space 6. The change detecting coil 7 outputs an electrical signal corresponding to the reduction of the magnetic flux.

Filed: 1994-05-12
Abstract: PURPOSE:To miniaturize an entire device and to surely fix it to a mounting position by connecting an elevation angle adjustment mechanism and an azimuth angle adjustment mechanism and bringing a mounting member for supporting an antenna device closer to the mounting position. CONSTITUTION:This mounting device 1 can be freely turnably moved along a pair of elevation angle adjustment grooves 35A or the like. Then, for the device 1, at the optional elevation angle capable of obtaining improved reception of an antenna member 6 to a vertical direction, by respectively tightening a spindle 43 and a rotation fulcrum shaft 40, the elevation angle of the antenna member 6 is fixed. Then, for the device 1, the spindle 19 for fixing an azimuth angle inserted through an azimuth adjustment groove 39 and a nut 20 for fixing the rotation fulcrum shaft 22 arranged in a rotation fulcrum hole 29 are respectively loosened. Thus, the device 1 is turned to a state where a bracket 6 connected with an azimuth angle adjustment member 2 can be freely rotatably moved with the spindle 22 as a rotation fulcrum. Then, since an antenna mounting member 3 is brought closer to the mounting position, the device is miniaturized.

Title: Phase control circuit
Inventor: GOTODA TAKAO
IPC: H03L7/06
Filed: 1988-04-21
Abstract: PURPOSE:To obtain a regenerated output with less jitter even if an input signal containing much jitter is inputted by inhibiting if a value that phase difference between an output signal and an input signal is integrated while the input signal is inputted M times is a leading phase, and not inhibiting if said value is a lagging phase. CONSTITUTION:The phase difference between the input signal and the output signal is integrated by an up-down counter 1 while the input signal is inputted M times, and if an integrated result output signal is leading, a 1, 0 signal generating part 11 outputs 1-level, and if lagging, it outputs 0-level, and a signal to be inputted to a rising differentiation circuit 9 is changed from the input signal so that the signal that the output signal is M-frequency divided by an M-frequency divider 2 is inputted, and the up-down counter 1 is cleared by the output of the differentiation circuit 9. Accordingly, the jitter comes to be the mean value during a period the input signal is inputted M times, and since phase control is performed one time when the input signal is inputted M times, the regenerated output with less jitter can be obtained even if much jitter is contained in the input signal.

CONSTITUTION:Turntable 23 is direct driven by DD motor 24, and its rotating speed is detected by frequency generator 26, whose detection signal (a) is supplied to speed servo circuit 27, where speed control signal S for DD motor 24 is generated. Part of speed detection signal (b), obtained from speed detection coil 6 fitted to the tone arm unit, is supplied to speed servo circuit 27. Then, circuit 27 generates a control signal which conpensates the variation in circumferential speed caused by the eccentricity of the center hole of the record and it is supplied to DD motor 24 being superposed upon the above-mentioned speed control signal S. Therefore the rotating speed of motor 24 is controlled according to speed detection signal (b), so that the circumferential speed of the record 25 at the trace point of the stylus caused by the eccentricity of the center hole of record 25 will be constant.

Title: Regenerative brake device of driving circuit for electric motor vehicle
Inventor: TSUJII HIROSHI
IPC: B60L7/14
Filed: 1988-04-20
Abstract: PURPOSE:To realize high energy recovery rate by connecting switch means to be turned ON at the time of regenerative braking and an additional surge absorber connected in series with a second snubber circuit in parallel with a first snubber circuit having a capacity which can absorb a turning OFF surge voltage at the time of power drive. CONSTITUTION:An EV controller 20 outputs a control signal to a PWM controller 30 in response to an acceleration signal and a brake signal of a vehicle. The controller 20 turns ON switch means 54 when a motor 4 is in a regeneratively braking state, and turns OFF it when it is in a power driving state. Accordingly, only a first snubber circuit 40 is operated at the time of power drive to absorb a surge voltage at the time of turning OFF with relatively small capacity. Since switch means 54 is turned OFF at the time of regeneratively braking, the first and second snubber circuits 40, 50 cooperatively absorb the surge voltage at the time of turning OFF thereby to cope with the surge voltage of a high level.
