Title: Size inspection instrument for empty can
Inventor: SUZUKI NOBUO
IPC: G01B21/02
Filed: 1987-07-29
Abstract: PURPOSE:To perform inspection in a short time, to automatize the inspection, and to improve its reliability by controlling respective mechanisms by a control mechanism, judging whether or not an empty can is normal from measurement results, and gathering the respective measurement results. CONSTITUTION:The empty bottomed cylindrical can which has a recessed part in the center of its bottom part toward its opening part is conveyed by a robot hand A from a can stocker B sectioned for each manufacture lot to each measuring mechanism. Measuring mechanisms C and D measure the height of the can by bringing probes into contact with the upper edge of the side part while rotating the empty can, and also clamp the side part by the probes to measure the thickness. A measuring mechanism E, on the other hand, inserts its probe into the recessed part to measure its depth. The can is taken out by the robot hand A after said measurement and a microcomputer (control mechanism) commands those operations to judge whether or not the empty can is normal from the measurement results and also gather the measurement results.

Abstract: PURPOSE:To enlarge the stroke of a plunger so as to increase flow by providing a column and a plunger opposedly in the axial hole of a solenoid part, and moving the column in the axial direction of the solenoid part at the time of moving the plunger by the energization of the solenoid to open a valve. CONSTITUTION:In the 'off' state, the force of a spring 15 surpasses the pressure of an input port 6, and a plunger 11 moves downward to close a first valve seat 7. A column 10 is stopped at a stopper 19, so that a gap Sa is formed between the column 10 and the plunger 11, and a gap Sb is formed between the stopper 19 and the inner wall of an exhaust chamber 18. As a result, a second valve seat 21 is opened, and compressed air is exhausted from an exhaust port 23. When a current is applied to a coil 9, the plunger 11 is sucked by a column 10 and moves up by a stroke Sa so as to close the valve seat 21 and open the first valve seat 7. Differential pressure is thereby generated between the exhaust chamber 18 and a communicating chamber 4, and the column 10 is moved up by a stroke Sb while sucking the plunger 11. The total stroke of the plunger 11 therefore becomes Sa + Sb.

Title: Method and equipment for controlling wind wiper motor
Inventor: YOANISU TOROUSASU
IPC: B60S1/08
Filed: 1992-07-17
Abstract: PURPOSE: To keep the smoothness of a glass surface by emitting a light beam on a part of a window glass, a light diffused by raindrops is reflected to an optical sensor which generates an electric signal, based on the detected value, to obtain a signal proportional to the rain intensity, thereby controlling the rotation of a wiper motor. CONSTITUTION: When an IR transmitter 1 irradiates a homogeneous light beam in a direction A, raindrops 4 on a front glass 3 reflect the light in a direction B which is detected by an IR sensor 2, while the raindrops always reciprocally move at an original position, owing to which the light modulation is performed to reflect the light as an alternating light. The bandwidth and the frequency of the alternating light indicate a measure for the number of raindrops on the glass 3, the rain intensity. Based on the bandwidth and the frequency, an evaluation circuit having an RC element 5, a diode 6 and an amplifier 7 forms a signal U/f which is used for the rotation speed control of the wiper motor. The glass surface can be kept smooth, without requirement for providing a foreign body on the glass 3.
