摘要:
In a recording sheet feeder, a recording sheet tray moving mechanism moves a recording sheet tray between an upper position, at which an uppermost recording sheet of a plurality of recording sheets loaded on the recording sheet tray contacts a feed roller, and a lower position, at which the uppermost recording sheet separates from the feed roller. A first eccentric cam and a second eccentric cam rotate to press down the recording sheet tray. A driving force switch member drives the recording sheet tray moving mechanism when a driver rotates in a first direction, and rotates a feed roller driving shaft mounted with the feed roller when the driver rotates in a second direction.

An attachment assist device includes an engagement member provided in one of a main body and a retractable unit, a catch portion provided in the other of the two, to engage the engagement member when the retractable unit is positioned at a drawing start position, and a drawing unit provided in the main body, to draw the retractable unit to a drawing completion position in the main body against multiple resistive forces acting on the retractable unit. On a projection plane on which the retractable unit is projected in an attachment direction, an engagement position where the engagement member engages the catch portion is disposed inside a rectangular area defined by two opposing corners respectively positioned at points of action of two of the multiple resistive forces acting on the retractable unit while the retractable unit moves from the drawing start position to the drawing completion position.

A zinc-based metal plated steel sheet is excellent in tribological properties during press forming. An oxide layer containing crystalline 3Zn(OH)2.ZnSO4. xH2O is formed on a plated surface. The oxide layer has a thickness of 10 nm or more. The crystalline oxide layer is composed of 3Zn(OH)2.ZnSO4.3-5H2O.

A sheet feed device includes a sheet tray and a guide unit. The sheet tray is configured to store a recording medium including a recording sheet. The guide unit is configured to support detachably the sheet tray. The guide unit includes a rotary member that is configured to contact an outer bottom surface of the sheet tray while contacting an outer side surface of the sheet tray, and rotate with mounting and detachment of the sheet tray. An image forming apparatus includes an image bearing member for bearing a latent image on a surface thereof, an exposure unit for exposing the image bearing member to form the latent image, a developing unit for developing the latent image with toner to form a visible image, a transfer unit for transferring the visible image onto the recording medium, and the sheet feed device.

A probe of scanning probe lithography which provides a long time of useful life. The probe has a tip part comprising a conductor and an insulator, the insulator is formed to cover the conductor, and the conductor is formed to provide a substantially uniform cross-sectional configuration with respect to a surface to be patterned through scanning.

A seat weight measuring apparatus having enough strength against load in a direction in which a rear side of the vehicle seat is lifted. The seat weight measuring apparatus includes a base frame with a mounting portion at the rear end side of the base frame. The mounting portion includes two stopper bolts as protective mechanisms for transmitting excessive load from a rear rail bracket to the base frame. One stopper bolt is a front (first) stopper bolt, and the other is a rear (second) stopper bolt. Therefore, the mounting portion has higher capability to withstand load than a mounting portion at the front end side of the base frame.
摘要:
To provide an electron exposure apparatus capable of providing high resolution and performing electron exposure at high speed, integrated tips are used. Only the tips provided at ends control distances between the tips and the surface of a wafer, and the tips used for electron exposure follow the wafer according to deformations of cantilevers, which occur due to the Coulomb force resultant from a voltage applied to each tip.
摘要:
A surgical cutting instrument which comprises an outer tubular member having a closed distal end closed and also having an aperture defined therein adjacent to the closed distal end which is in communication with the hollow of the outer tubular member and an inner tubular member having an open distal end which is slidably disposed in the outer tubular member such that the inner tubular member slides along its longitudinal axis first and second positions. The distal end of the inner tube has also has a scraper region defined therein. The scraper region is curled so as to represent a curved shape corresponding to a portion of a circle having a diameter greater than the outer diameter of the inner tubular member, so that when the inner tubular member is moved within the outer tubular member, the curled scraper region can be forcibly brought into sliding contact with an inner peripheral surface of the outer tubular member. Therefore, during the movement of the inner tubular member from the first position towards the second position relative to the outer tubular member, the curled scraper region is moved past the aperture in the outer tubular member to cut a tissue entering into the outer tubular member through the aperture.
