IPC: F17C13/08
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To omit the soldering work itself, and to eliminate the generation of trouble such as low workability at the time of providing a pressurized coil, lowering of the pressurizing performance due to low-temperature, and lowering of the vacuum degree inside of a vacuum double-layer. SOLUTION: At the time of fixing a coil part of a pressurized coil 9 to the inner wall of a bottom part of an outer tank 2, most of fixation of the coil part is performed by using saddles 12. As a method for fixing the saddle 12 to the inner wall of the outer tank 12, spot welding as one kind of electric welding is desirable. As a material of the saddle 12, soft steel having a high strength and a high heat conductivity is desirable. At the time of performing the fixation using the saddle 12, since contact area of the pressurized coil 9 with the inner wall of the bottom part of the outer tank 2 is smaller in comparison with a soldering method, full length of the pressurized coil 9 is prolonged in comparison with a conventional one and the number of the saddle 12 is increased and size thereof is enlarged so as to secure the heat conductive area.  The number of winding of the coil part is desirably set at 4 or more.

Title: Variable length segment control system
Inventor: TAJIRI KAZUO
IPC: G06F12/14
Filed: 1980-06-09
Abstract: PURPOSE:To use the address space effectively, by using stored contents of information indicating a continuable section of addresses to detect whether the base address and the effective address exist in the same segment or not. CONSTITUTION:Sections of section number n-3-n are used as one segment. If the section number of the base address is n-2, the last section number n of the segment to which the base address belongs is read out from a storage mechanism 4 and is stored in a register 16. Next, a part 17, which indicates the section number, of an effective address 13 is sent to a comparator 19. The comparator 19 compares this part 17 with contents of the register 16, and transmits an interrupt signal through a signal line 21 if the former is larger than the latter. Thus, the size of the segment is determined in accordance with the size of the address space which the program requires, thereby using the address space effectively.

Filed: 1994-04-15
Abstract: PURPOSE:To prevent sticking of chips within a return pipe by providing a returning means for supplying water and oil removed from chips by means of a centrifuge to the return pipe between the centrifuge and the return pipe. CONSTITUTION:A coolant removed from chips by means of a deoil device 11 and a coolant supplied from a lubrication pipe 21 are returned to a return pipe 4 via a return pipe 25. At this time, the coolants flow naturally as the return pipe 25 is extended obliquely downward and are returned to the return pipe 4. Thus, the coolants flow to a metal pipe 2 after flowing through the return pipe 4. Sludge-formed chips flew into the return pipe 4 being stuck to a chain 8 or a plate 9 tend to stick to the inside thereof. However, these chips in sludge forms are pushed out by means of the coolants flowing from the deoil device 11 via the return pipe 25 and thus sticking thereof within the return pipe 4 is prevented.
