Patent JP-S6129299-A (JP)
Title: Piezoelectric transducer
Inventor: KAJIWARA KAZUHIKO
IPC: H04R17/00
Filed: 1984-07-19
Abstract: PURPOSE:To reduce the number of parts and to shorten hours required for assembly work by obtaining a resistance for braking by means of a thin fluid layer formed by a recessed part provided at the bottom of an insulator and a printed circuit board. CONSTITUTION:A piezoelectric element 22 is coupled to a metallic plate 21 to constitution a diaphragm. A thin fluid layer 33 consists of a shallow recessed part 34 provided at the bottom of an insulator 23 and a printed circuit board 26. The resistance of the thin fluid layer 33 acts as a resonance brake resistance, and this resistance value is decided by the thickness and length of the thin fluid layer 33. Accordingly, the resistance value can be set arbitrarily in accordance with the shapes of the insulator 23 and the printed circuit board 26, both of which form the thin fluid layer 33. As the resistance for braking is decided in accordance with the shapes of the insulator and printed circuit board, a stable resistance value can be obtained. Further an acoustic resistance material is made unnecessary to reduce the cost.

Filed: 1987-06-18
Abstract: PURPOSE:To convey plural types of platelike parts by means of suction force with the operational program conformed to these types by letting a sensor detect a projection of a discrimination plate and making it so as to select the operational program. CONSTITUTION:A robot 5 attracts parts 3 piece by piece from one at the topmost part in accordance with the operational program conformed to types of the parts 2 and goes up. And, it conveys the attracted part 2 to a work bench 7 for its setting. During operation, the robot is on standby in a state of releasing the part 2 and, after the operation is over, it attracts the part 2 again, conveying it to a discharge table 8, and the part 2 is discharged out. After the abovementioned action is repeated as to the parts 2 in the same form, the robot 5 attracts a discrimination plate 3 and goes up. If so, a sensor 6 of the robot 5 detects a projection 31 of this discrimination plate 3, and feeds this detected signal to a control part of the robot 5. With this constitution, the robot 5 conveys the attracted discrimination plate 3 to the discharge table 8 and discharges it. Simultaneously with this, the operational program is selected to another operational program that is conformed to types of the part 2 to be attractively conveyed at the next time.

Title: Raster distortion correcting circuit
Inventor: TOSHIYASU MASAYUKI
IPC: H04N3/237
Filed: 1985-07-08
Abstract: PURPOSE:To make the correction of bilateral symmetry possible by supplying the pulses of the same frequency with resonance frequency of a resonance circuit to a horizontal winding. CONSTITUTION:Horizontal period pulse (l) is converted to the pulse string of horizontal synchronism 1/2, that is, the pulse (m) of double repetitive frequency by a frequency multiplying circuit 10 that constitutes a frequency adjusting means from, for instance, a fly-back transformer etc., and applied to the horizontal winding 5a of an upper and lower bobbin distortion correcting transformer. The frequency of applied pulse (m) outputted from the frequency multiplying circuit 10 nearly coincides with a horizontal secondary resonance frequency formed by a vertical winding 5b, a phase adjusting coil 6 and a resonance capacitor 7. Accordingly, a raster distortion correcting current (n) free from attenuation can be obtained. Thus, the attenuation of generated current of the resonance circuit is reduced, and the correction of bilateral symmetry can be obtained.

IPC: B03C3/155
Filed: 1990-06-08
Abstract: PURPOSE:To reduce the sizes of air ports for stacking and discharging air which are installed on a rear tray, without lowering of performance by arranging an intake port and an exhaust port in front and in rear in the center of a rear tray of a car body and making air currents intersect each other in the central air intake and exhaust portion. CONSTITUTION:The air sucked by a fan 23 passes an intake port 47 through an intake grid to enter a discharger 25. In the discharger 25, discharging is performed from a discharge electrode to an opposite electrode to apply electric charges to dust in sucked air. The sucked air including charged dust is spread under a lower wall 50 of an exhaust path and under a circuit chamber 44 to pass throughout a filter 26. Thus, dust is adsorbed to the electrically earthed filter 26, so that only the clean air passes through an air passage 30 to reach an eddy chamber 24 and be supplied from the exhaust port 46 through an exhaust grid into the interior of a car. In this arrangement, as the air intake port 47 and the position of the filter 26 where negative pressure is applied, the exhaust port 46 and the position of the fan 23 and the intake port 47 and the exhaust port 46 are arranged in front and in rear in the center, air currents intersect each other in the center.

Abstract: PURPOSE:To make it possible to achieve stable detection of output at all times and also appropriate setting of threshold value voltage at the same time, by employing such a mechanism for a circuit as to be able to form a threshold value voltage in accordance with an input potential. CONSTITUTION:When potential difference between input terminals IN<+> and IN<-> is zero, emitter potential of a transistor (TR) 16 becomes lower than that of TR17 by I.R18. At this time, TR20 and TR21 are in OFF position, and current passing through TR17 puts TR22 in On position, and an output terminal OUT becomes grounding potential. And then, when input voltage becomes higher than I.R<18> and emitter potential of TR16 becomes higher than that of TR17, current passes through TR16, TR20 and TR21 become in On position, and TR22 becomes in OFF position. At this time, if the terminal OUT is connected to a prescribed potential point of positive polarity through a load element, a prescribed potential is obtained onto the terminal OUT.
