IPC: D21F3/08
Filed: 1989-06-12
Abstract: PURPOSE: To press a hollow roll locally to a counter roll by making the pressure of one sealing member between a pair of sealing members installed at a crosshead, higher than the pressure of the other sealing member. CONSTITUTION: A roll pair has a lower roll 10 and an upper roll 10.

Title: Molding of insulated member for electric appliance
Inventor: YUUZA HISASHI
IPC: H01B19/00
Filed: 1977-12-09
Abstract: PURPOSE: To prevent a recess from taking place in molding, by appropriately controlling the added quantity of a hardening accelerator to make the speed of hardening rection uniform.  
     CONSTITUTION: A conductor 8 is set between metal molds 6, 7. A mixed resin A consisting of 100 parts by weight of a resin and 1 part by weight of the hardening accelerator is poured into the molds. Then, another mixed resin B consisting of 100 parts by weight of the resin and 0.1 part by weight of the hardening accelerator is poured into the molds. Thereafter, the metal molds are heated to harden to harden the pured resins A, B. Since the resin A has a higher viscosity than the resin B, the hardening progresses upward in the metal molds. The poured resin shortage is eliminated by the poured resin B during the hardening contraction. Therefore, no recess is produced on the surface of the mold insulated product 11.

Title: Heat sink and manufacture thereof
Inventor: HISAMORI YOICHI
IPC: B22D19/00
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To achieve high reliability against leakage of water and to reduce manufacturing cost by providing a nipple around a pipe forming a passage of cooling water, where the nipple serves as a connector between a pipe end, and a heat sink body which is formed integrally with the pipe. SOLUTION: A heat sink body 21, which is formed by die-casting aluminum, is connected to nipples 30, each serving as a connector at the end of a pipe 27 serving as a flow passage. A tube in which cooling water flows is connected to the nipple 30, cooling water passes through the pipe 27, and resistors sandwiching both surfaces of the heat sink body 26 are cooled by heat transfer and conduction. Since the passage is completely independent, it is only necessary to inspect leakage on joints between the nipples 30 and the pipes 27. Moreover, die-cast is adopted as a highly efficient processing method, in which the pipes and the heat sink body 26 are formed integrally. Thus, it is possible to eliminate the necessity for assembling, and the working time is reduced.

Abstract: PURPOSE: To perform welding efficiently with good strength balance by making the torch speed at the time of downward moving faster than that at the uperward moving and welding more by one pass in the case of moving a torch around the opposing portions of pipe bodies and welding the same.  
     CONSTITUTION: Welding is performed by setting a torch T first in the position of 11 o'clock, starting arc, and turning clockwise and moving the torch T along the weld zone while weaving the same within the range of a fixed size in the axial length direction of pipe bodies P, P. In this case, the moving speed of the torch T is made such that the moving speed from the position of 12 o'clock until it reaches the position of 6 o'clock becomes slightly faster than the moving speed from 6 o'clock until it reaches 12 o'clock. In this way, the torch T is rotated twice and in succession it is shifted to the 3rd rotation. In the 3rd rotation, the torch is turned and moved from the position of 11 o'clock up to 6 o'clock and the region to be welded while the torch T is moving downward is welded more by 1 pass than the region to be welded while the torch is moving upward.

Abstract: PURPOSE:To achieve prevention of erroneous detection while accurately detecting the presence and passage of a detecting object, by receiving two light emissions respectively corresponding to two different timing signals by two light receiving means. CONSTITUTION:Light emitting elements 24 and 25 repeat separate flashing driven by light emitting element driving circuits 22 and 23 according to timing signals T1 and T2 outputted from a timing signal generation circuit 21. When a detecting object 10 does not exist, these lights travel straight separately to be received with light receiving elements 26 and 27 and when it does, the lights are reflected on the object to be received with the elements 27 and 26. Then, timing detection circuits 32 and 33 check to see from which of the elements 24 and 25 the lights are received with the elements 26 and 27 while identifying extraneous light relying on neither of the timing signals to prevent influence thereof. In addition, a signal processing circuit 34 judges the presence of the object 10 depending on with which of the elements 26 and 27 lights detected from the elements 24 and 25 are received.
