Title: Method for packing microrecesses and apparatus therefor
Inventor: KOGURE NAOAKI
IPC: C23C18/31
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To enable the use of materials, such as copper and copper alloys, having a low specific resistance as a packing material by immersing base materials having microrecesses into a plating liquid and rotating a plating tank at a prescribed rotating speed, thereby packing the prescribed material into the recesses. SOLUTION: The plating tank 10 in which the many semiconductor base materials 1 are housed is constituted nearly to an annular shape. The inside wall of the plating tank 10 and a revolving shaft 11 are connected by spokes 12. The plating tank 10 is rotated at the prescribed rotating speed during a plating stage. The surfaces of the semiconductor base materials 1 are arranged in a direction perpendicular to the radial direction of the ring and the depth direction of the microrecesses, i.e., contact holes and grooves, is the radial direction of the ring. The plating liquid is, therefore, gradually infiltrated into the contact holes and grooves which are the microrecesses by the centrifugal force generated by rotating of the plating tank 10. Consequently, the copper, etc., may be well packed even into the microrecesses having a high aspect ratio.

Abstract: PURPOSE:To perform good printing without generating the blind hammering against a pedestal, by a method wherein the upper part of the pedestal having a projection provided to the lower part thereof from the projection arranging part is cut into a tapered shape inclined to the side of a hammering surface. CONSTITUTION:A daisy wheel is constituted so that the upper part of the pedestal 2 thereof from the projection 1 performing the formation of a character provided to said pedestal 2 is cut into a tapered shape inclined to a hammering surface. The height of the pedestal 2 is set so as to be made substantially the same to that of the guide groove of the hammer and the triangle rib 3 corresponding to the guide groove of the hammer is provided to the back surface of the pedestal. In this inventive daisy wheel having the pedestal mentioned above, since the pedestal 2 is cut into a tapered shape, the stand 2 does not strike a platen 6 at the time of printing and the generation of pedestal hammering observed heretofore can be prevented. Even when the stop accuracy of the daisy wheel is slightly inferior, the triangle rib is housed in the wide groove t1 formed to the upper end part of the guide groove of the hammer at first and subsequently gradually housed in the guide groove toward the narrow lower end part of said groove to prescribe a hammering position and, therefore, the blind hammering of the pedestal can be prevented.

Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To provide a water supply unit having a signal storage water heater body and two water channels in which boiling up of bath water is prevented from being delayed at the time of simultaneous combustion. SOLUTION: A bypass 25 communicating between a water supply path 11 and a hot water supply path 12 while bypassing a hot water supply heat exchanger 10 is provided with means 26 for controlling the quantity of water passing through the bypass 25 variably by varying the valve opening.
