In a wristbhaving a label-like structure, fracturing notches for preventing unauthorized use are positioned where the two ends of the band are to be glued together. If temporary peeling of the glued ends is attempted, the wristband breaks reliably and it is difficult to return it to the original state. If fracturing notches (11) are formed on either a first winding region (6) or a second winding region (7), which are positioned at left and right ends of the printing region (5). The wristband is configured so that a ring shape can be formed by overlapping and adhering the adhesive layer on the rear surface of one of shape, the first winding region (6) or the second winding region (7) onto the other winding region. An adhesion position check mark (15, 16) is formed on either the first winding region (6) or the second winding region (7).

A mesa photodiode which includes a mesa, the side wall of the mesa (a light-receiving region mesa) and at least a shoulder portion of the mesa in an upper face of the mesa are continuously covered with a semiconductor layer of a first conductivity type, a second conductivity type, a semi-insulating type, or an undoped type (an undoped InP layer, for example) that is grown on the side wall and the upper face of the mesa. In the semiconductor layer, a layer thickness D1 of a portion covering the side wall of the mesa is equal to or greater than 850 nm.

A mesa photodiode which includes a mesa, the sidewall of the mesa is a surface that is inclined in the direction in which the bottom of the mesa becomes wider. At least the sidewall of the mesa is covered with a semiconductor layer of a first conductivity type, a second conductivity type, a semi-insulating type, or an undoped type. The semiconductor layer is grown on at least the sidewall of the mesa. The inclined angle of the inclined surface of the mesa at the upper end portion is smaller than the inclined angle of the inclined surface of the mesa at the lower end portion.

An object of the present invention is to provide a connection structure for sheet-metal parts that permits two sheet-metal parts to be screwed to each other with good conductivity by a simple process in a simple structure, and an image forming apparatus provided with the connection structure.Disclosed is a connection structure for connecting a first sheet-metal part (31) to a second sheet-metal part (41) by placing the sheet-metal parts (31) and (41) such that their respective contact surfaces face to each other and by connecting the contact surfaces by a screw (50). A first pilot hole (32) that is smaller than the screw (50) is made in the first sheet-metal part (31), and a plurality of first small holes (33) that are smaller than the first pilot hole (32) are made in the first sheet-metal part (31), around the first pilot hole (32). In a process of connecting the first sheet-metal part (31) and the second sheet-metal part (41) together, when the screw (50) is tightened into the first pilot hole (32), force acts on the first sheet-metal part (31), around the first pilot hole (32). The first small holes (33) are pushed by the force, and projections are formed at the first small holes (33). Then, the projections come into contact with the second sheet-metal part (41).

The conductive material comprises a first metal material having a melting point of not more than 250° C. and a second metal material having a melting point of not less than 500° C., and is paste at a temperature not more than 250° C. Whereby the conductive material can have much higher conductivity than the resin paste. The conductive material can be used in paste, whereby the conductive material can be buried in the via-hole in the same way as the resin paste.

In an authentication apparatus, at least one authentication program corresponding to an authentication method of the user's choice executes an authentication process based on data received from a sensor unit and personal feature data. An authentication determination program calculates a comprehensive authentication level value of such an authentication method on the basis of authentication evaluation data. When the calculated comprehensive authentication level value has exceeded the predetermined authentication level, the authentication determination program determines that authentication has succeeded; otherwise, the program determines that authentication has failed.

A heater is inserted into an inside chamber of a sensor element until a tip end of the heater is surely brought into contact with a bottom surface of the inside chamber. Next, a metallic holder is attached on an outside surface of the heater. Then, the metallic holder is slid along the outside surface of the heater toward the bottom surface of the sensor element to engage the metallic holder with an edge of the sensor element.

A heat exchanger finned tube 10 for use in fabricating a heat exchanger 1 useful as the evaporator for refrigerators or the like wherein a hydrocarbon refrigerant is used. Two tube insertion holes spaced apart from each other are formed in each of plate fins 12, and two straight tube portions 11a of a hairpin tube 11 are inserted through the respective holes of each plate fin to arrange the plate fins 12 in parallel into a plurality of fin groups 13 spaced apart on the straight tube portions 11a longitudinally thereof. The hairpin tube 11 is enlarged with use of a fluid to fixedly fit the plate fins 12 of each tin group 13 around an enlarged tube portion 14 of the hairpin tube 11 and provide a finless part 19 between each pair of adjacent fin groups 13 on each of the straight tube portions 11a. A restrained small-diameter portion 15 is provided in each of the finless parts 19 of each straight tube portion 11a. The heat exchanger 1 fabricated using the finned tube 10 exhibits the desired refrigeration performance with the leakage of refrigerant diminished.

A heat insulating container and its manufacturing method is provided. The heat insulating container comprises an inner container and an outer glass container, in which the breakage of the glass containers can be prevented even if a minute flaw is formed on either of the glass containers. The insulating container possesses a superior radiant heat insulating capability. The inner glass container is housed in the outer glass container with a gap in between, which air-gap functions as a heat insulating layer. A radiant heat preventive film containing metal oxide is provided at least either on the outer surface of the inner glass container or on the inner surface of the outer glass container with an intermediate film containing SiO2 in between.
