Inventor: HIGAKI NORIHIDE
IPC: B23K26/12
Filed: 1983-07-26
Abstract: PURPOSE:To provide a titled device which prevents sticking of the material evaporating and scattering from a work to the bottom surface of protective glass by providing a nozzle diverging toward the work side on the bottom surface of the protective glass for a working lens and admitting a gas into the nozzle. CONSTITUTION:A laser welding device performs welding by condensing the laser beam 1 oscillated from a laser oscillator for working by a lens 2 for working and irradiating a work consisting of a plateworked part 6 and a shaft part 7 through protective glass for preventing the damage of said lens 2.

Title: Linear moving block device
Inventor: YAMADA KAZUO
IPC: F16C29/12
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To reduce rattling between a linear-moving block and a rail by rolling some of a plurality of rollers in noncontact with the bottom face of a rectangular groove but in contact with its upper face, while rolling the other rollers in noncontact with the upper face of the rectangular groove but in contact with the bottom face. SOLUTION: A first roller 40 and a forth roller 43 from the right roll in contact with the upper face 613 of a rectangular groove formed in the side face of a rail but in noncontact with the bottom face 614. On the other hand, a second roller 41 and a third roller 42 roll in noncontact with the upper face 613 of the rectangular groove of the rail, but in contact with the bottom face 614. When some of the rollers roll in contact with the upper face 613 of the rectangular groove and the other rollers are rolled in contact with the bottom face of the longitudinal groove, rattling caused by rotating a linear-moving block about the horizontal direction perpendicular to the longitudinal direction of the rail arranged horizontally can be extremely reduced.

Title: Fabrication of semiconductor device
Inventor: FUKUSHIMA YASUSHI
IPC: H01L27/088
Filed: 1995-05-11
Abstract: PURPOSE: To deposit a gate oxide having two kinds of thickness by forming an anti-oxidation layer covering only a semiconductor substrate in a first forming region and a gate electrode and forming a bird's beak between a second forming region and the gate electrode by wet oxidation. CONSTITUTION: Gate electrodes 12, 12' are formed in regions A, B. Insulating oxide layers 14, 14' are also formed around the gate electrodes 12, 12'. After depositing nitride 15 by about 100nm as an anti-oxidation layer, the nitride is removed selectively from the region B. Silicon oxide is then deposited on a semiconductor substrate 11 in the region B by wet oxidation. Consequently, the insulating oxide layer 14' becomes thick on the surface and side face of the gate electrode 12' but a bird's beak is formed between the gate electrode 12' and the semiconductor substrate 11 and thereby a gate oxide layer 16' has a thickness of 12-16nm. With such method, semiconductor elements having gate oxide layer of different thickness can be fabricated on a same semiconductor substrate.

Title: Improved heat transfer tube with internal protruded streak section and manufacture thereof
Inventor: CUNNINGHAM JAMES LEE
IPC: B21D53/06
Filed: 1986-06-12
Abstract: A heat transfer tube (10) has mechanical enhancements which improve the heat transfer properties of at least the outer (12) surface of the tube. An optional internal enhancement, which is useful on either boiling or condensing tubes, comprises a plurality of closely spaced helical ridges (16) which provide increased surface area and are positioned at an angle which gives them a tendency to swirl liquid flowing through the tube. The external enhancement, which is applicable to boiling tubes, is provided by successive cross-grooving and rolling operations performed after finning. The finning operation, in a preferred embodiment for nucleate boiling, produces fins while the cross-grooving and rolling operation deforms the tips of the fins and causes the surface of the tube to have the general appearance of a grid of generally rectangular flattened blocks (see Figure 8) which are wider than the fins and separated by narrow openings (20) between the fins and narrow grooves normal thereto. The roots of the fins and the cavities or channels formed therein under the flattened fin tips are of much greater width than the surface openings so that the vapour bubbles can travel outwardly through the cavity and to and through the narrow openings. The cavities and narrow openings and the grooves all cooperate as part of a flow and pumping system so that the vapour bubbles can readily be carried away from the tube and so that fresh liquid can circulate to the nucleation sites. The rolling operation is performed in a manner such that the cavities produced will be both larger and smaller than the optimum minimum pore size for nucleate boiling of a particular fluid under a particular set of operating conditions.

Abstract: PURPOSE:To secure an alternation hardware system area (HSA) and expansion HSA as occasion demands without securing a large-capacity HSA in advance, by making part of a software using area (SUA) dynamically fetchable in an HSA while a control program (OS) is run. CONSTITUTION:When a fault occurs in an HSA of an instruction executing section 5 in an instruction processor 1 while an instruction is executed, the fault is detected by means of a fault detecting section 9. When the detected fault is discriminated as a fixed fault, an interruption is made against on OS. After accepting the interruption, the OS understands the requested HSA capacity from the interrupting information and checks whether a sufficient unused area present in a SUA or not. If no vacant area matching the requested HSA capacity exists in the SUA, the OS tries to release part of the SUA area. When a sufficient area can be secured in the SUA, the OS sets an OSA starting and ending addresses and a shifting process is performed.
