Title: Method for underwaters concrete casting
Inventor: HOSOKAWA YOSHIO
IPC: E02D15/06
Filed: 1979-02-15
Abstract: PURPOSE: To make highly-reliable underwaters concrete casting by a process wherein a tremie pipe having a switching valve in the vicinity of the lower end is placed  underwaters and concrete is thrown onto a plunger slidably fitted in the pipe down  underwaters with the opening of the switching valve adjusted.  
     CONSTITUTION: A tremie pipe 1 having a switch valve 2 about 1m upward for example of the lower end is placed underwaters with the valve 2 opened. Next, the valve 2 is closed, water level 3' is raised above that outside by supplying water to the pipe 1, a plunger 4 is slidably fitted in the pipe 1, and concrete 5 is thrown in. Next, the water level in the pipe is lowered by gradually opening the valve 2 so that concrete drops by the balance between the weight thereof and water pressure. When having reached the valve 2, the plunger 4 is pushed out from the lower end of the pipe 1 with the valve 2 fully opened, and concrete is cast underwaters through the pipe 1. The valve 2 can be closed when concrete casting is interrupted on accident for example.

Title: Paper feeder
Inventor: TAKANO TSUNEICHI
IPC: B41J11/26
Filed: 1985-01-31
Abstract: PURPOSE:To prevent the occurrence of paper jam by providing at least one projection to the peripheral face of a pinch roller. CONSTITUTION:At least one projection 8a is provided on the periphery of a pinch roller 8, and the tip of the projection 8a is shaped into a circular arc form in such a way that frictional force when contracted with a platen roller 1 through a fan-fold paper 18 is smaller and the contact area is also smaller. When the fan-fold paper is set and a stepping motor 6 is actuated to feed papers, the projection 8a comes into contact with the platen roller 1 at least one time during the rotation period of the roller 8. Since the projection 8a contacts with the paper 18 in a spot contact manner, the frictional force becomes smaller, and if great tension is applied to the paper 18, slipping is occurred and the feeding amount of paper becomes smaller. In case where greater tension is applied to the paper 18, the paper 18 is pulled back. As a result, the paper 18 is in natural state, and the breakage of small holes of the paper 18 and the occurrence of paper jam can be prevented.

Title: Lead-connecting method for part-mounting substrate
Inventor: YAMAMURA KEIJI
IPC: H01L23/485
Filed: 1982-02-02
Abstract: PURPOSE:To eliminate poor connection between leads and pads by a method wherein a continuous layer of solder paste is placed on a lineup of bonding pads including dummy pads and the sloder is melt to coat the pads by means of the reflow solder method. CONSTITUTION:At the both ends of a region wherein bonding pads 4 are arranged, dummy pads 10 are juxtapositioned with the same pitch, made of the same substance and assuming the same configuration but not participating in the formation of an electric circuit. A belt-shaped solder paste 5 is printed on the pads 4, 10. Application of heat to the layer 5 in a reflow process melts the layer 5 and the molten solder moves toward affinity-rich metal surface of the pads 4 due to self-alignment. Accordingly, the part of the substrate 3 exposed between pads 4 gets rid of solder, for the removal of short circuits between the pads 4. Reduction in solder layer thickness is observed only in the vicinity of pads 10 where the two extremities of the layer 5 sag.
