There is disclosed a ceramic heater 11 comprising: a plate member 12 made of insulating ceramics in which one or more pair(s) of through-holes 13 are formed; a conductive layer 19 made of conductive ceramics; and a coating layer 21 made of insulating ceramics; wherein a joint member 14 made of conductive ceramics is inserted into the through-hole; an end face 16 of the joint member has a same plane with a main surface 15 of the plate member; the joint member is coated with the conductive layer 19 and thereby fixed to the plate member and also connected with the conductive layer having a heater pattern 20; and an opposite side of the joint member projects from the plate member and the projecting portion 18 constitutes a terminal on which the coating layer is not formed. There can be provided a ceramic heater by which an object to be heated being put directly thereon can be heated uniformly and of which heating efficiency is high and in which the heater main body is not large in size and is compact and scattering of impurities or particles is small and which has a long operating life and is inexpensive.

There is provided a high-voltage pulse generator with a reduced radius of rotation and improved performance, and a lighting apparatus and a vehicle having the high-voltage pulse generator. The high-voltage pulse generator includes a pulse transformer in which a primary winding and a secondary winding are wound on a core, a discharge lamp connector which is formed in a tube shape having an opened front surface and a bottom out of an insulating material and which has an inner-electrode terminal electrically connected to a high voltage part of the secondary winding in the bottom, and a pulse generating capacitor and a discharge switch electrically connected to the primary winding of the pulse transformer. The discharge lamp connector is disposed so that the center thereof is located in a center line passing through a substantial center in an axis direction (a direction parallel to a center line) of the pulse transformer and perpendicular to the axis direction. The capacitor and the discharge switch are disposed to be opposed to the high voltage part of the secondary winding and a high voltage area including the inner-electrode terminal with the discharge lamp connector therebetween.

A disclosure is made of a subterranean connecting method and a connecting apparatus therefor which are suitable for use when two shield machines are used to excavate a pair of tunnel sections from both ends of a tunnel, and the tunnel sections are connected to each other in mid course. During underground connection, it is important to secure sealing and water retarding with respect to soil and water pressure exerted by the ground in the vicinity of the connecting section. For this purpose, in the connecting apparatus, a penetration ring is arranged in one of the shield machines, and a penetration chamber in which the penetration ring is accommodated is arranged in the other shield machine. Both the both shield machines face each other with a slight gap remaining therebetween and, subsequently, the penetration ring is moved forward and penetrates into the penetration chamber of the mating shield machine. By this penetration, the area between both the shield machines are closed by the penetration ring. In this condition, both the shield machines are disassembled, and the wall surface of the connecting section including the penetration ring is covered, so completing the subterranean connecting step. According to the connection using such a penetration ring, sealing and water retarding with respect to the soil and water pressure in the vicinity of the connecting section can be secured.

An osteosynthetic pin characterized in that the pin is formed substantially of a poly-L-lactic acid having a molecular weight of at least about 70,000, and is formed by axially drawing about 2 to about 10 times at an elevated temperature of about 70.degree. to about 120.degree. C.
摘要:
In the structure for reinforcing a concrete member and the reinforcing method of the present invention, a reinforcing sheet is arranged and joined to a various kinds of concrete member, such as column, beam, wall, floor, and the like, by applying the reinforcing sheet to the surface of the concrete member and attaching to the fixing anchors joined to the concrete member or the other concrete member surrounding the concrete member. The fixing anchor comprises a large amount of reinforcing fiber, and is obtained by bundling a part of the reinforcing fiber. The unbundled portion of the fixing anchor is spread along the surface of the concrete member. The reinforcing sheet is over-lapped to the unbundled portion using resin adhesives. In addition, reinforcing fibers, such as carbon fiber, aramid fiber, glass fiber, and the like are preferably used as the material comprising the fixing anchor and reinforcing sheet. Thereby, the reinforcing member can be joined via the fixing anchor to the concrete members. Therefore, it is possible to securely join the edges of the reinforcing member, and reliably exert the reinforcing effects on the concrete member.
