IPC: E04H7/06
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To reduce the construction period by turning partial roofs to the circumferential direction along a ring-shaped guide supporting the arcuate side of the partial roof after the partial roofs have been constructed one by one at a specified place at the opening side and positioning them. SOLUTION: A cylindrical continuous underground wall 3 is provided in the ground 1 and a recessed part is formed in the ground 1. Support members 24 are radially fixed onto the one side bottom face of the recessed part and a plurality of supports 25 are fixed on the support members 24 and further, jacks 26 are fitted onto the supports 25. A plurality of concrete forms 27 are arranged on the jacks 26. Concrete is placed on the forms 27 and hardened to form a semicircular dome-shaped roof element 6a. Other jacks 26 except the central jack 26a are lowered and the roof element 6a is rotated by a half turn around the supporting point and fixed therein. Thereafter, the other half elements 6a is constructed again to form the roof.  Support members 24 or the like are taken out and then, the ground is excavated and after the bottom slab, the side wall, etc., are formed, a cover layer is put thereon to form an underground tank. In this way, the construction period can be reduced.

Title: Semiconductor device
Inventor: AONO YOICHI
IPC: H01L21/28
Filed: 1986-11-10
Abstract: PURPOSE:To prevent an electrode from being exfoliated during a wire-bonding process, to prevent a purple plaque from being produced and to enhance the yield and the reliability of a semiconductor device by a method wherein an Al electrode or an Al alloy electrode is formed on a semiconductor substrate whose surface has been made rough by anisotropic etching, a pad coated with a gold film is formed on the surface of the assembly through a refractory metal or a refractory metal nitride film and a gold wire is connected to said pad. CONSTITUTION:An Al film 2 is formed on a semiconductor substrate 1 whose surface 1' has been made rough; a titanium nitride (TiN) film 5 is applied on the surface; in addition, an Au film 6 is formed on the surface; an Au wire 3 is bonded to the Au film 6. The rough surface of the semiconductor substrate 1 can be obtained in such a way that the surface is etched by using a mixed solution of an aqueous solution of sodium hydroxide and another aqueous solution of sodium hypochlorite. Because uneven parts are formed on the surface of the substrate with an electrode constructed in this manner, the effective surface area is increased and the bonding strength is enhanced even with the small pad area of about 30 mum. Because the TiN film 5 acting as a reaction-preventing layer exists between the Al film 2 and the Au film 6, no purple plaque is produced.

Title: Min/max circuit
Inventor: YAMAKAWA RETSU
IPC: H03K17/00
Filed: 1986-11-13
Abstract: PURPOSE:To omit a compensator for both MAX/MIN circuits by connecting both circuits comprising each a comparator and a compensator in cascade. CONSTITUTION:The compensator of a circuit E-MIN is to compensate a position voltage shift in the emitter junction of the comparator of the pre-stage. Moreover, the compensator in a 2-input MAX circuit is to compensate a negative voltage shift in the emitter junction of the comparator of the pre-stage. Since the compensator of the E-MIN and the compensator of the MAX circuit compensate the voltage shift in opposite direction to each other, even when the compensators are omitted, there is no change in a valve of a final output (z), then both compensators are omitted. Thus, the number of transistors is saved, the operating speed is quickened and to power consumption is reduced.

Title: Pipe front-edge crimp device
Inventor: UIRUHERUMUSU PII EICHI KIYASUT
IPC: B21D41/04
Filed: 1987-10-24
Abstract: An apparatus for crimping the leading edge of continuously produced spiral pipes is disclosed. The apparatus includes upper and lower passive crimping rollers, which are rotatably mounted adjacent each other in a holder. The holder is carried by a guide rail system which slides in the axial direction of the spirally moving pipe. The holder and rollers are rotated between a down position, where the continuously produced pipe will move freely over the crimping apparatus, and an up position where the leading edge of the pipe will pass between the upper and lower crimping rollers. When the crimping apparatus is in the up position and the leading edge of the pipe is between the crimping rollers, the lower roller is raised until the rollers cooperate to crimp the leading edge of the pipe. The spirally moving pipe will exert a force on these rollers, which causes the guide means, which carries the rollers, to move axially with the pipe. The crimping rollers will crimp the entire circumference of the pipe's leading edge as the crimping rollers move axially with the pipe and the leading edge of the pipe rotates between the rollers. When the entire leading edge of the pipe has been crimped, the holder and rollers are rotated to their down position, so that the pipe production can resume without obstruction by the crimping apparatus.

CONSTITUTION:A printed pattern 11 on a printed board 7 is filled with a paste- like anisotropic conductive bonding agent 12 diluted by a diluent. The bonding agent 12 is transferred to pads 13. The pads 13 are heated with a heater 14 on the way to transfer and suspended at the top of the heater 12. The diluent on the exposed surface of the bonding agent 12 is evaporated. In this state, the pads 13 are transferred to the surface of a board 8 and the bonding agent 13 is transferred to the board 8. A dryer 16 is arranged to blow hot air and evaporate the diluent on the exposed surface of the bonding agent 12. After this process, a second board is hot-pressed to the second board by sandwiching the bonding agent. This construction makes it possible to enhance the adhesive power in the exposed part, to print thick film anisotropic bonding agent and to make definite connection as well.
