Title: Method of positioning lead terminal
Inventor: SASADA YOICHI
IPC: H05K1/02
Filed: 1986-12-09
Abstract: PURPOSE:To detect defective positional displacement easily by forming two conductor line patterns, a space of which is slightly wider than lead terminals, on both sides of a lead-terminal mounting predetermined position and discriminating between defective and nondefective positioning by the presence of conduction with conductor lines. CONSTITUTION:Two conductor patterns 7, spaces of which are wider than lead terminals 3, are shaped extending over the rear 6 from the side surface 5 of a ceramic circuit substrate 1. The conductor patterns 7 at every two represent the positions of welding of the lead terminals 3, and right positioning is displayed when the lead terminals 3 are welded so as to be brought to the central positions of the positions. Conductor patterns 8 consisting of vertical lines are formed, crossed at right angles with the conductor patterns 7 composed of such horizontal lines at the center of the rear 6. The defective or nondefective positioning of a lead frame is determined by investigating the presence of conduction between the lead frame and the conductor patterns 8. Since the conductor patterns 7 as dummy patterns are shaped brought near to the lead terminals 3, the rear must be cut by using a laser, etc., after the completion of inspection in order to ensure reliability.

IPC: G01S7/527
Filed: 1986-12-09
Abstract: PURPOSE:To enable even an object being detected in extremely short range to be detected by discriminating received wave signal from interference wave not only by difference in positions along time axis but also by the one in voltage values. CONSTITUTION:Fundamental pulse A from a fundamental pulse generating circuit 1 is inputted to an oscillator circuit 2 and an inhibiting signal forming circuit 5. The circuit 2 outputs oscillation signals according to the pulse A to electricity/sound converting means 4 via an amplifier 3. Ultrasonic wave fed from the means 4 is reflected from an object 11 to be detected and received by the means 4 to be converted to electric signal. The electric signal is shaped to received wave signal S and interference wave T via an amplifier circuit 6 and a detecting circuit 7 to be inputted to an inhibiting circuit 8. On the other hand, the circuit 5 affinely forms inhibiting signal C with the same waveform and the same voltage value as those of the signal S and the interference wave T and inputs the signal C to the circuit 8. Since the signal C and the interference wave T have the same timing, both cancel each other out. Only the signal S is outputted from the circuit 8 and the signal S is outputted via a smoothing circuit 9 and a switching circuit 10 as detection signal.

Title: Trigger type atomizer
Inventor: TAZAKI TAKAHARU
IPC: B05B11/00
Filed: 1994-11-01
Abstract: PURPOSE: To eliminate such a fault as atomizing pressure is lowered and atomization is made incomplete at a time for finishing atomization in a trigger type atomizer in which liquid in a cylinder is spouted from a nozzle of the tip of an ejection cylinder through a discharge valve by drawing a trigger and regulating the inside of the cylinder to high pressure. CONSTITUTION: When the inside of a cylinder 18 is regulated to high pressure by drawing a trigger 35, an automatic piston 40 resists energization of a coil spring 49 by diameter difference of the front and rear both pistons 42, 44 and is advanced. A discharge valve 48 is opened and liquid in the cylinder is atomized from the tip of an ejection cylinder 28. Therefore, liquid pressure in the cylinder is lowered in comparison with energization of the above-memtioned spring 49 and the discharge valve 48 is closed simultaneously. When the inside of the cylinder is regulated to negative pressure by releasing the trigger 35 and advancing the piston member 36 through the spring 49, liquid in a vessel body is introduced into the cylinder 18 through a lifting pipe 13, a suction hole 21 and a suction valve 47.

Title: Focus controller and tracking controller for optical disk device
Inventor: TAKAHASHI SATORU
IPC: G11B7/085
Filed: 1989-11-10
Abstract: PURPOSE:To always obtain the objective servo performance by applying the cancellation of an offset in a focus error signal and the adjustment of detection gain automatically with an arithmetic processing of a digital signal processor DSP. CONSTITUTION:When a DSP 6 detects the loading of an optical disk 1, a current commanding value moving a lens actuator 2 in a direction (a) is changed to read a peak value of a focus error signal generated before and behind a focal position. Then a conversion constant converted from a prescribed detection gain and an offset of a signal are calculated from the peak value. Then the DSP 6 cancels the offset of the read signal and converts the detection gain by using the conversion constant to apply the detection of a focal position and the compensation characteristic at servo operation. Thus, the offset of the signal and the detection gain are not influenced. The operation is implemented automatically every time a disk is loaded to obtain the servo characteristic being always an object.

Title: Image processor
Inventor: ECHIZENYA TATSUO
IPC: G06T1/00
Filed: 1989-11-14
Abstract: PURPOSE:To always apply a desired binarizing process to the image of a work regardless of the voltage waveforms by using selectively the threshold levels suited to the video voltage waveform to be binarized. CONSTITUTION:The image of a work photographed by an image pickup means 10 is converted into the electric signals by a signal conversion means 11. A data processing means 14 obtains the maximum level, the minimum level, the average level, and the medium level between the maximum and minimum levels out of those electric signals. A floating threshold level generating means 12 produces a floating threshold level from the electric signals. At the same time, the threshold level selection means 19 and 20 perform the comparison between the average and medium levels and select the medium or floating threshold level as the threshold level that is used for binarization based on the result of the comparison. Thus the image of the work is always binarized as desired regardless of the voltage waveform of the work image.

Abstract: PURPOSE:To improve engaging performance of a pinion to the ring gear and reduce the capacity of an electromagnetic switch by movably composing the lower end part of a shift lever and the arm part of an interlocking body, engaged with the lower end part, in an axis direction in a reduction gear. CONSTITUTION:The electrification of an electromagnetic switch 34 causes the absorption of a plunger 37 to rotate a shift lever 44 in an anticlockwise direction with a hook 43. This engages the lower end part 44a of the shift lever 44 with the end part of the arm part 64b of an interlocking body 64 to forward move the end part in an axis direction. Consequently an output shaft 60 is advanced to engage a pinion 61 with a ring gear. Concurrently the armature shaft 53 of a D.C. motor 51 is rotated and deceleratedly rotated with a toothed wheel reduction gear 70, and rotation is transmitted to the output shaft 60 via an overrunning clutch 80. The starting of an engine causes the turning-off of the electromagnetic switch 34 to rotate the shift lever 44 to a retreat side. As a result, the output shaft 60 is retreated with a return spring 87 to be caught at a returned position with a bearing 77 via the pinion 61 and the overruning clutch 80.
