IPC: B21D53/06
Filed: 1988-05-27
Abstract: PURPOSE:To perform mass production with good workability by forming grooves on the inside surface of a tube whose outside diameter exceeds a specific value and sinking a tube with a backward tension of a specific condition for heat transfer tubes having specific outer diameter, spiral grooves of a specific depth, width, and of a specific number. CONSTITUTION:A heat transfer tube having an outside diameter D0 of 3-7mm and spiral grooves or continued grooves in the tube axial direction whose groove depth (h) of 0.1-0.3mm, groove width W1 of 0.05-0.45mm, and the number of grooves in 25-70 is manufactured. On the inside surface of a tube whose outside diameter D0 exceeds 7mm, grooves of a depth (h), width W1 in the above ranges, and a specific number of grooves are formed. Sinking by draft ratio of 16% per sinking with a backward tension being 30-60% of the breaking force of a tube is performed to reduce the D0 to 3-6mm. By synergetic effect of the backward tension and draft ratio, reduction of a diameter to 3-6mm with a very little variation range of wall thickness and groove depth is performable for even a small tube having a diameter of <=7mm. Hence, mass production of small diameter heat transfer tubes with good workability is performable without complicated working design.

IPC: G06F13/36
Filed: 1985-06-13
Abstract: PURPOSE:To attain the transfer of data at a high speed by setting two FIFO buffers storing the data of n-bit width respectively in parallel between a host bus of 2n-bit width and a local bus of n-bit width. CONSTITUTION:A multiplexer/demultiplexer 19, an FIFO buffer 17 and a buffer circuit 18 are provided between a host bus 14 and a local bus 12. Thus the DMA transfer is possible with 16-bit and 8-bit widths. The changeover between these two data widths is carried out when the execution is started according to the contents of information written to an input/output controller from a host system. Then it is decided from the information set to a control register 10 whether the DMA transfer of 8 bits or 16 bits should be carried out. Based on this information, a local processor 2 decides the data width and informs it to an FIFO controller 20 before execution of the DMA transfer. Thus the controller 20 works by said information.

The entire length of the movement is divided at an arbitrary pitch based on the counted value A in the counter A, and the error in the measured value epsilon=A-B is computed at every pitch. Then the error epsilon is stored in an ROM50 in advance. When the feeding shaft is rotated, the accurate amount of the movement is computed and displayed from the amount of rotation A and said error epsilon. Furthermore the change in the rotating direction of the feeding mechanism is detected, the amount of the blacklash is computed, and the measurement error is prevented.

Inventor: TAKENOUCHI NAOKO
IPC: H01L29/78
Filed: 1986-06-05
Abstract: PURPOSE:To increase the potential at a source edge and to suppress punch- through occurring in the vicinity of a surface, by forming an impurity layer, whose conductivity type is the same as that of a substrate, at a shallow part on the side of at least a source diffused layer in a channel region. CONSTITUTION:An impurity layer, whose concentration is higher than a substrate 11 and conductivity type is the same as that of the substrate 11, is provided on the side of at least source diffused layer in the channel part of an MOSFET. The junction depth of said impurity layer is shallower than the junction depth of a low concentration diffused layer, which is formed in at least a gate electrode 14 by a self-aligning mode, among source and drain diffused layers. Punch-through occurring especially in the vicinity of the surface can be suppressed by forming a p<-> diffused layer at a shallow part on the side of the gate electrode in at least the source region. The p<-> diffused layer is formed at a part shallower than a low concentration n<-> diffused layer among the source and drain diffused layer. Therefore, a high concentration n<+> diffused layer is not contacted with the p<-> diffused layer directly. Thus breakdown strength of the junction can be increased.
