Title: Control method of pilot signal and valve assembly
Inventor: MAIKERU EDOWAADO ROBAATO
IPC: F15B11/028
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To provide an easy and low-cost controlling method for controlling an output pressure of a booster pressure regulator precisely and stably. SOLUTION: In a pilot signal controller, a fluid pressure from an output port 16 in a booster pressure regulator 12 is converted into a voltage signal V(t) by means of a pressure/voltage converter 26, and using the voltage signal V(t) as an improving signal on a feedback loop 24, a pilot pressure of a valve 18 is controlled for regulating output of the booster regulator 12. In the pilot signal controller, the voltage signal V(t) is multiplied by a proportional factor A based on a size of the booster pressure regulator 12. In a signal auxiliary loop 30 of the feedback loop 24, the first derivative of the voltage signal is taken and added to the multiplied signal so as to generate a feedback signal F(t). The feedback signal F(t) is subtracted from a command voltage C(t) to generate an error signal E(t) inputted as a pilot signal to the valve 18.

Abstract: PROBLEM TO BE SOLVED: To prevent the backlash of a drop rod by providing a slide contact member facing a guide section and kept in slide contact with the protruded drop rod preferentially to the guide face of the guide section, and forming the slide contact member with a resin sheet. SOLUTION: When a flush bolt 6a is fitted to a stile to fit a drop rod 12 to a drop rod guide 21, the drop rod 12 is moved from below toward the drop rod guide 21 fitted at the upper section of the stile, and the tip section of the drop rod 12 is inserted into a guide section 22a. The notch section of a resin sheet 25 is pushed open to be split into a wedge shape by the tip section of the drop rod 12, the guide section 22a is warped from the inside to the outside after the drop rod 12, and a slide contact piece 27a covers the inside edge section and guide face of the guide section 22a and is inserted between the drop rod 12 and the guide face. Since the slide contact piece 27a is inserted into the gap between the drop rod 12 and the guide face of the guide section 22a, the backlash of the drop rod 12 in the drop rod guide 21 can be prevented.

Title: Method for determining angle of depression in image pickup unit
Inventor: IMANISHI KATSUYUKI
IPC: B60R21/00
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To determine the angle of depression which fluctuates due to pitching of a pair of image pickup units for image detector calculating the distance from a pair of image to an object accurately through a simple method. SOLUTION: The pavement parallax of image is previously calculated optogeometrically for a plurality of angles of depression within a predetermined range. On the other hand, a correlation value is calculated from the difference between a translated image and other image. Using the movement of translation for the minimum correlation value as a parallax, a correlation value obtained during the process for calculating the distance to object, where the pavement parallax calculated for each angle of depression is equal to the movement of translation of one image at the time of calculating a correlation value, is multivalued (Step 103). Variation is then calculated for the angle of depression of multivalued correlation value and the angle of depression for maximum variation is determined as the angle of depression of image pickup unit (Step 104).

IPC: F16K31/06
Filed: 1988-12-26
Abstract: PURPOSE:To reduce a noise, when a plunger closely adheres to a yoke, corresponding to a change of viscosity of silicone oil, when it is in low temperature, by constituting a device applying to the plunger work of forming a groove for the oil to pass and controlling a suction speed of the plunger. CONSTITUTION:A plunger 2 applies work of forming an oil passing groove 2a in a shape with the point end large and the final end small. Consequently, when suction is started, silicone oil 3a in an oil case 3 is allowed to flow in from a large part of the oil passing groove 2a in the point end of the plunger 2 reaching a side 3c, and the plunger 2 sucks the oil at a high suction speed with a less damper effect. However, the plunger 2, approaching its final end in accordance with proximity to a yoke 1, decreases the oil passing groove 2a, increasing the damper effect and decreasing the suction speed, and in the point of time the plunger 2 closely adheres to the yoke 1, the maximum damper effect is obtained. In this way, a noise can be reduced in the time of close adherence.
