    摘要: A three-dimensional resolution chart is used to adjust the position of a solid-state image detector 4 in a given image-forming optical system. A plurality of blocks 10a are provided on an upper surface of a resolution chart 10. Each block 10a has an adjusting pattern A-D depicted on a slant surface thereof. An image of each adjusting pattern A-D is formed on the solid-state image detector 4 through a master lens 2. The contrast integration value F is calculated based on the image of the adjusting pattern at each of a plurality of designated areas hj (j=1 - - - n) on the slant surface of each block 10a provided on the resolution chart 10, to find out a specific position on each block where the contrast integration value F becomes maximum, thereby identifying the specific position as focus point of the master lens 2. The back focus of the solid-state image detector 4 is calculated based on thus obtained focus point. An optimum gradient (.alpha., .beta.) of the solid-state image detector 4 is calculated based on a three-dimensional relationship between plural focus points of the master lens 2 detected on the plural blocks 10a. Finally, each positioning mechanism 11 adjusts each solid-state image detector 4 to the calculated optimum position or at the optimum gradient.

    摘要: To minimize the amount of air that may enter the damper chamber in a normally closed solenoid valve to stably maintain the damper capacity, the normally closed solenoid valve has a valve housing and a movable element. A cylinder having an open end is formed in one of the valve housing and the movable element. The cylinder has an inner diameter smaller than the outer diameter of a trunk of the movable element. A piston provided on the other of the valve chamber and the movable element is movable relative to the cylinder as the movable member moves. The piston is inserted into the cylinder through its open end to define a damper chamber between the piston and the cylinder. A restricted passage is formed between the damper chamber and the valve chamber through which hydraulic fluid can be moved between the valve chamber and the damper chamber.

    摘要: The invention realizes certainly detecting two or more positions on a touch panel that are touched at the same time. A drive circuit selects one from X lines, and supplies an alternating drive voltage to the selected line. A multiplexer selects a first sense line and a second sense line from Y lines that extend to cross the X lines. A charge amplifier outputs an output voltage corresponding to a difference between a first capacitance between the first sense line and the X line selected by the drive circuit and a second capacitance between the second sense line and the X line selected by the drive circuit. A touch position is then detected based on the output voltage of the charge amplifier.
