A camera module according to one embodiment of this invention has a sensor substrate, a lens holder, and a shield being fixed to the lens holder. The lens holder is composed of a tubular portion including a lens and a top board having an opening. The lens holder is fixed by a second adhesive provided more inside than an edge of the sensor substrate. The shield has a tubular portion and a top board. The tubular portion is composed of a small-diameter portion, a step portion, and a large-diameter portion. The shield is disposed so that the step portion is in contact with a portion between the edge of the sensor substrate and the second adhesive, and, at the same time, the top board of the lens holder is located in an opening formed in the top board of the shield.

There is disclosed a method for fabricating a camera module includes the steps of: disposing a camera module body inside of a die; filling the die with a resin blocking a light; curing the resin; and removing the camera module body and the resin from the die. Here, disposing the camera module body inside of the die is disposing the camera module body having a lens holder secured on a sensor board inside of the die in such a manner that the side surface of the camera module body is not brought into contact with the side surface of the die. Filling the die with the resin is covering the upper end of the die with a lid so as to closely enclose the inside of the die, followed by filling the die with the resin. Taking the camera module body and the resin from the die is taking, from the die, the camera module body and the resin formed around the camera module body in close contact.

An externally toothed portion of a cup-shaped flexible externally toothed gear of a wave gear device is flexed into an ellipsoidal shape by a six-roller-type wave generator. A region of an inner peripheral surface of the ellipsoidally flexed externally toothed portion that is positioned on a major axis of the ellipsoidal shape is maximally inclined. First rollers of the wave generator are arranged so that the incline is identical to the incline of the region of the inner peripheral surface. A circular outer peripheral surface of the first rollers can be brought into contact with the region of the inner peripheral surface in an external-tooth tooth-trace direction without deflection; therefore, the angular transmission precision of the wave gear device can be improved.

Disclosed is a wave-type linear motion mechanism including a hydraulic pressure chamber for applying a retention force in the axial direction to a rigid screw member which moves in a linear fashion. Regulating valves are provided in the hydraulic pressure chamber, and these regulating valves open during the rotation of a wave generator so that no hydraulic pressure is exerted on the rigid screw member which moves in a linear fashion. During the rotation of the wave generator the regulating valves close to establish an airtight state in the hydraulic pressure chamber, and a hydraulic pressure is exerted as a retention force on the rigid screw member. Although restricted by the meshing strength between the rigid screw member and a flexible screw member and the buckling strength of the flexible screw member, the retention force of the wave-type linear motion mechanism is able to be increased.

A robot hand converts the longitudinal extending and retracting motion of an actuating rod of a linear actuator into opening and closing motion of left and right first links via a link mechanism. The link mechanism includes left and right middle links composed of coil springs. When the left and right first links come in contact with an object to be gripped, the middle links elastically deform and expand, and the force gripping the object gradually increases due to the elastic deformation of the middle links. It is possible to prevent a large gripping force from acting suddenly on the object and to prevent the object from being deformed, damaged, or otherwise suffering harmful effects.

摘要:
Three or more circuits including a driving inverter circuit and rectifier circuits are connected in series, each of the circuits including a high-voltage side MOSFET and a low-voltage side MOSFET connected in series as well as a smoothing capacitor having positive and negative terminals between which the MOSFETs are connected. LC series circuits, each including a capacitor and an inductor, are disposed individually between one specific circuit and the other circuits with periods of resonance of the LC series circuits made equal to one another. In performing DC/DC power conversion through charging and discharging operation of the capacitors, a resonance phenomenon of the LC series circuits is used to improve conversion efficiency and achieve a reduction in size of the apparatus structure.
摘要:
Three or more circuits, in which series-connected low-voltage and high-voltage side switches including MOSFETs including parasitic diodes are connected across positive and negative terminals of each of smoothing capacitors, are connected in series. One of elementary series circuits, each including a capacitor and an inductor, is disposed between any adjacent two of the circuits with the elementary series circuits set to have the same period of resonance. The MOSFETs of rectifier circuits are brought into an ON state simultaneously with the MOSFETs of a driving inverter circuit and brought into an OFF state earlier than the MOSFETs of the driving inverter circuit by a period of time not exceeding a time period equal to (period of resonance)/2. A resonance phenomenon of the capacitor and the inductor is used and conduction loss in the rectifier circuits is reduced in DC/DC power conversion performed through charging and discharging operation of the capacitor.
