An opening for a replacement bit can be closed without a large drive force, the replacement bit can be replaced without being moved, and the workability of replacement is not impaired. A rear surface frame (29) forms a workspace (28) on the rear surface side of a spoke front surface plate (21), and openings (33) are formed on the spoke front surface plate (21) such that a replacement bit (31) can be inserted into and removed from the opening (33). A bit guide body (37) having a bit guide hole (38) is provided on the rear surface side of the opening (33). A gate plate (34) is provided which has valve ports (35) capable of communicating and closing the openings (33) and the bit guide holes (38). A gate opening/closing device (36) is provided which can turn the gate plate (34) to open or close the openings (33).

An information processing apparatus of the present invention includes an upper casing 11, a lower casing 12 coupled to the upper casing 11 and forming a space for housing at least an electrical element, and a keyboard 3 disposed on the upper casing 11. The lower casing 12 includes a wall portion 13d arranged to stand from the inner bottom 12d, and a supporting face 13a formed integrally with the wall portion 13d from the wall portion 13d in a direction substantially parallel to the inner bottom 12d. The supporting face 13a is disposed at a position where the rear side of the operational side of the keyboard 13 can be supported. With such a configuration, key touch feeling of the keyboard can be prevented from declining, and an excellently robust information processing apparatus can be achieved.

An exterior enclosure has an elevated portion forming a top plane. The elevated portion is surrounded by two pairs of mutually opposed ridge lines. The top plane is formed to have a concavely curved surface with respect to one of the two pairs of ridge lines. The exterior enclosure is manufactured by fixing a plate-shaped metallic blank material in place and pressing the blank material in a heated condition so that the elevated portion is formed with the top plane formed thereon. In the forming process of the elevated portion, the elevated portion is so formed as to have a concavely curved surface with respect to one of the two pairs of the ridge lines.

It is intended to provide multi-piece circuit boards capable of preventing lowering of strength of joint sections between piece sections after cutoff and other sections, and determining material of flame sections regardless of material of a piece section, and board manufacturing method of such multi-piece circuit boards. For a mixed board including a defective piece section and a good piece section in a state in which an outermost layer is not formed yet, cut lines are made around bridges and are joined together by adhesive, and an upper layer is provided thereon, whereby a multi-piece circuit board mounted on good piece sections only is formed. A frame section may be formed by arranging respective piece sections manufactured in advance at positions at which the piece sections are to be present and injecting fluid matter to surround the respective piece sections arranged to form the frame section. Furthermore, joints between respective piece sections and frame section may be provided on the frame section to surround roots of respective bridges. Furthermore, an adhesive sheet may cover each joint.

A temperature control system for electric surface heater of piled layers of a heating element across which a commercial AC source current is fed and a thermosensitive electrode opposing the element through thermosensitive element showing negative impedance characteristics with temperature rise. In the system, an AC signal voltage different from the source current is applied between the heating element and the thermosensitive electrode, and excessive variations in the signal voltage responsive to the negative impedance of the thermosensitive element is detected to disconnect or connect the heating element and the source.

A card holding apparatus of the present invention includes a seal member 12 that is provided so as to surround the periphery of a contact terminal portion 11. When a lid 3 is positioned in a closed position with a smart card 100 retained by the lid 3, the seal member 12 comes into close contact with the periphery of a terminal 101. Thus, even when foreign matter such as water or dust intrudes into a space between the lid 3 and a housing 1, adhesion of such foreign matter to contact terminals 11a or the terminal 101 can be prevented.

A nozzle 33 is formed on a distal end side of a cylinder 3. The nozzle 33 has an intermediate portion 3b formed such that a tip 7 is freely attachable thereto and detachable therefrom. The intermediate portion 3b of the nozzle 33 is formed with an annular projection 3e for retaining the tip 7. The tip 7 has a thick portion 7a provided in a root portion thereof and formed larger in diameter than a root portion 3a of the nozzle 33 to be abuttable against a tip releasing member 11. Along an inner periphery of the root portion of the tip 7, an annular projection 7b is formed to contact with the annular projection 3e of the nozzle 33 thereby providing a seal with the nozzle 33. Both the annular projections 3e and 7b of the nozzle 33 and the tip 7 are arranged to reach a position where a sound of abutment is produced between the root end surface of the tip 7 and the shoulder of the nozzle 33 at the completion of fitting of the tip 7 onto the nozzle 33.

An extension device 5 is engaged in a connector provided on one side of a lower case 102 of a cabinet 100 of an PIP apparatus PI. An adjustable foot 6 is provided on the bottom surface 102u to adjust the extension device 5 and the cabinet 100 in height. Therefore, the cabinet 100 can be horizontally placed on a plane. When the extension device 6 is approximately equal in height to the lower case 102, the adjustable foot is retracted into the lower case 102. Therefore, the thickness of the PIP apparatus PI can be minimized.
