Abstract: An optical structure is disposed on a surface of a device substrate, and a lens system for introducing external light into a solid-state image pickup device is placed in the center of the optical structure. The outer shape of the optical structure seen from the light incident side of the lens system is rectangular, and its plane shape forms a rectangular frame section. An intermediate structure is disposed between the device substrate and the optical structure. The intermediate structure has a fitting section for fitting the optical structure in a part of side faces of the frame section.

Abstract: A lens driving apparatus includes: a first yoke having an inner peripheral wall and an outer peripheral wall placed to be concentric with each other and forming a rectangular U-shape cross section and a cylindrical shape; a second yoke placed at an outer side of the first yoke to be concentric with the first yoke and forming a rectangular U-shape cross section and a cylindrical shape; a base; a first magnet and a first coil arranged in a rectangular U-shape interior of the first yoke; a second magnet and a second coil arranged in a rectangular U-shape interior of the second yoke; a first lens support member; and a second lens support member. The second lens support member is placed at an inner peripheral side of the second yoke and has the second coil fixed onto an outer periphery thereof. The first lens support member is linearly moved in a direction of an optical axis of a lens by an electromagnetic force caused by passing current through the first coil.

Abstract: A lens driving apparatus includes a first yoke 7 having an inner peripheral wall 7a and an outer peripheral wall 7b placed to be concentric with each other and forming a rectangular U-shape cross section and a cylindrical shape; a second yoke 12 placed at an outer side of the first yoke 7 be concentric with the first yoke 7 and forming a rectangular U-shape cross section and a cylindrical shape; a base 2; a first magnet 6 and a first coil 4 arranged in a rectangular U-shape interior of the first yoke 7; a second magnet 11 and a second coil 9 arranged in a rectangular U-shape interior of the second yoke 12; a first lens support member 5; and a second lens support member 10. The second lens support member 10 is placed at an inner peripheral side of the second yoke 12 and having the second coil 9 fixed onto an outer periphery. The first lens support member 5 is linearly moved in a direction of an optical axis of a lens by an electromagnetic force caused by passing current through the first coil 4.

Abstract: An electromagnetic actuator comprises: a magnet; a pole piece mounted to the magnet; a yoke facing the pole piece; a coil base having a vibration coil; leaf springs for supporting the coil base and a weight; a case for enclosing them; a cover for covering one side of the case; and a diaphragm having a voice coil, wherein the arms of the coil base are inserted through notches formed in the yoke, and the vibration coil and the voice coil is disposed in a gap in which the pole piece and the yoke face each other. The weight vibrates by the application of a low-frequency current to the vibration coil, and the diaphragm vibrates by the application of a high-frequency current to the voice coil.

Abstract: A stamping implement includes: a stamp unit having a stamping element made up of a porous stamp compound having continuous pores at the lower end thereof; an outer cylinder having an opening at the lower end thereof, a cutout portion on the side thereof and the stamp unit fixed therein; an inner cylinder having an opening at the lower end thereof a window hole on the side thereof and being arranged outside the stamp unit and inside the outer cylinder with the lower end thereof projected out below the lower end of the outer cylinder so as to be slidable in the vertical direction relative to the outer cylinder; and a lid configured of an arm portion pivoted at an axial support near the upper end thereof and a shield portion at the lower end of the arm portion, and is so constructed that the axial support of the lid is axially supported so as to be rotatable by a frame of the window hole of the inner cylinder, and the lid rotates in linkage with the vertical movement of the inner cylinder relative to the outer c

Abstract: A multiplex writing implement includes a mechanical pencil refill and ball-point pen refill which can be selectively used as desired, and is equipped with a delivering mechanism for delivering a stick-shaped article such as an eraser etc. The multiplex writing implement further includes: a front barrel for accommodating at least tip portions of these refills; a middle barrel for accommodating the remaining parts of these refills; a rear barrel which is able to rotate clockwise or counterclockwise relative to the middle barrel; and a cylindrical cam which moves integrally with the rear barrel and, in accordance with the rotational direction of the rear barrel, allows selective use of one of the refills by projecting any one of the refills from the front end of the front barrel and retracting the other refill. In this configuration, the front and middle barrels are integrally joined in such a state that each barrel is prevented from rotating and falling off relative to the other barrel.

Abstract: A method of controlling the characteristics of an aqueous solution for treating the surfaces of a web moving continuously in a lengthwise direction, consists of changing certain characteristics, such as the specific gravity, of the aqueous solution at a fundamental period depending on physical parameters, such as the speed at which the web is driven and/or the width of the web, by feedforward control, and changing that fundamental period in accordance with the difference between the measured characteristics of the aqueous solution and reference characteristics according to which the aqueous solution is to be controlled, by feedback control.
