A manufacturing method of a vibrator includes processing a tip of a contact part arranged on an elastic body of the vibrator by lapping or grinding processing so that part of the tip has a plane shape in part of a spherical shape.

Manufacturing method of vibrator

A vibration-type actuator can be miniaturized and can stabilize a pressure state between a driven body and a vibration body. A pressurizing unit applies a pressure force between projections on the vibration body and the driven body. A piezoelectric device connected to the vibration body on a surface opposite to the projections moves the driven body by vibration occurring in the vibration body when a drive voltage is applied. The pressurizing unit includes an energizing member, its support member, and a transfer member. A length of a contact area between the projections and the driven body is shorter than a length of an area in which the transfer member transfers the pressure force from the energizing member to the vibration body and a length of a contact area between the energizing member and the support member, in a direction perpendicular to the moving direction and to a pressurizing direction by the pressurizing unit.

Vibration-type actuator and optical device using the same

A vibration-type actuator includes a supporting mechanism functioning such that a reaction force from a base against a pressing force from a driven member to an elastic member is dispersed to a vibrating portion and a supported portion of the elastic member. The supported portion is supported by the base with a vibration-isolating member interposed therebetween.

A vibrator includes an elastic body bonded to an electrical-mechanical energy converting element and including at least two contact parts, in which the at least two contact parts have convex shapes, shapes of surfaces of the at least two contact parts are part of spherical shapes, and rising directions of the at least two contact parts toward a member to be driven when the member is driven are different.

Vibrator, vibration type driving apparatus and manufacturing method of vibrator

A liquid discharging apparatus in which a liquid is flowed in one direction in a circulation flow path at the time of non-discharge, and the flow path is refilled with liquid from both directions at the time of discharge. The liquid discharging apparatus includes a pressure adjustment unit that satisfies a condition 'Pu&#x3e;Pd, Pn&#x3e;&#x2212;Pd', where Pu denotes a fluid pressure at a predetermined position on the upstream side of a discharge port, Pd denotes a fluid pressure at a predetermined position on the downstream side thereof, and Pn denotes a pressure equivalent to a capillary force of the discharge port for absorbing the liquid from the flow path into the discharge port immediately after the liquid has been discharged therefrom.

Liquid discharging apparatus

There is provided a biochemical reaction cartridge comprising at least one chemical reaction chamber that accommodates a solution for biochemically treating a sample, a reaction chamber for performing detection reaction of a target substance in the biochemically treated sample, and a detection reaction information fetching section for fetching information on whether or not the detection reaction is performed, wherein the biochemical reaction cartridge is provided with a covering unit that can cover and expose at least the reaction information fetching section.

A registration adjusting is performed for reducing an error in registration adjustment due to tolerance in manufacturing of a linear encoder scale. In the method, a printing head located at a position closest to a center position among a plurality of printing heads arranged along a primary scanning direction is taken as a reference printing head for registration adjustment.

A folding mechanism portion for folding leg portions (8, 11) along a support portion (5) of an image input apparatus (1) is provided in a base portion (7). This mechanism is constituted by two legs which extend from the base portion substantially in the shape of 'L' within a horizontal plane when used, and can be folded to become parallel to the support portion (5) when not used. A pan base (2) on the upper end of the support portion (5) has an electrical connector and can be detached.
