Patent JP-S6489343-A (JP)
Title: Manufacture of semiconductor device
Inventor: TOMIJIMA YASUSHI
IPC: H01L23/52
Filed: 1987-09-29
Abstract: PURPOSE:To improve the coverage of upper layer wirings in a through hole without necessity of shrink-fitting by employing the same metal film as that of upper layer wirings as a mask when a through hole is opened in an interlayer insulating film. CONSTITUTION:Lower layer wirings 3 are formed through a thin insulating film 2 on a semiconductor substrate 1. Then, an interlayer insulating film 4 is formed on the whole surface, a first metal film made of the same metal as that of upper layer wirings is further deposited thereon, an opening 5 is formed, and a mask 6 for a through hole is formed. Thereafter, with the mask 6 a through hole 7 is formed in the film 4. Then, a second metal film 8 is formed on the whole surface. Subsequently, the film 8 and the metal film used as the mask 6 under the film 8 are patterned, thereby forming upper layer wirings 10 made of the film 8 and the first metal film. According to this manufacturing method, since there is no moisture, shrink-fitting is not required, and since the same metal film as that of the upper layer wirings is formed on the periphery of the through hole at the side of the upper layer wirings, the coverage of the upper layer wiring in the through hole is improved.

Title: Piston for internal combustion engine
Inventor: FUKAMACHI MASATOSHI
IPC: F02F3/00
Filed: 1991-09-26
Abstract: PURPOSE:To prevent oil from flowing from the piston outer circumferential surface positioned blow an axial line into a combustion chamber, in an internal combustion engine in which the axial line of a cylinder is inclined to a vertical line. CONSTITUTION:A piston 27 which fits slidably to a cylinder 24 having an inclining axial line L is formed in its elliptic cross section shape, and an expander 66 and oil ring 97 are fitted in an oil ring groove 276 formed on the outer circumferential surface of the piston 27. The number of oil return holes 277 for connecting together inner circumferential surfaces of the oil ring groove 276 and the piston 27 is more above the axial line L, and less below it. Since the amount of oil which makes reverse flow along the outer circumferential surface of the piston 27 passing the oil return holes 277 positioned below is reduced even if oil stagnates below the inner circumferential surface of the piston 27 by action of gravitational force, it is possible to reduce the amount of oil which flows in the combustion chamber side passing the oil ring 97.

Title: Modular motor
Inventor: SOOHAN RARU ATSUPARU
IPC: F04C2/10
Filed: 1993-09-08
Abstract: PURPOSE: To render it easy to increase volumetric efficiency of a modular motor, remove a forward package and permit service and repair of the motor. CONSTITUTION: A modular motor 11 is provided for use with a forward package 13, the motor including an end cap 15, a valve plate 17, a gerotor gear set 19, and a flange member 21, all of which are held together. Bolts are located radially inward of O-ring seals 81, 83, 85. Any leakage past heads 27 of the bolts flows into a sealed cavity 79 defined by the forward package 13. The modular arrangement permits service and repair of the forward package without disassembly of the modular motor, and the smaller bolt circle diameter of the bolts results in greater stiffness of the end cap 15 and the flange member 21, thereby reducing deflection and increasing volumetric efficiency of the modular motor.

Title: Corrosion apparatus for observing metal texture
Inventor: FUKUDA KIYOSHI
IPC: G01N1/28
Filed: 1987-10-02
Abstract: PURPOSE:To make it possible to yield corrosion uniformly without yielding corrosion irregularities, by providing a metal-surface adhering cell having a corrosion-liquid injecting nozzle, an air nozzle, a cleaning liquid injecting nozzle and a corrosion-liquid/cleaning-liquid sucking pipe on the inner surface. CONSTITUTION:In a metal-surface adhering cell 5, a corrosion-liquid injecting nozzle 18 and a cleaning liquid sucking pipe 21 are attached. The inner surface of a central hole 1 of a medium pressure rotor in a steam turbine is corroded with a corrosion apparatus for observing metal texture. At this time the metal- surface adhering cell 5 is brought into contact with the inner surface of the central hole 1. Thereafter corrosion liquid is injected through the corrosion-liquid injecting nozzle 18 so as to fill the inside sufficiently. The surface of the metal is sufficiently corroded. Thereafter, air is sent into the inside of the metal- surface adhering cell 5 through an air nozzle 20 so as to increase pressure. At the same time, the inside of the corrosion-liquid/cleaning-liquid sucking pipe 21 is made to be a vacuum. Since the internal pressure in the metal-surface adhering cell 5 is sufficiently increased with the air through the air nozzle 20, most of the corrosion liquid is sucked. The cleaning work is repeated several times. Thus the replica picking up surface can be corroded without irregularities.

IPC: B23K9/095
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To solve a problem of the arc climbing to a side wall of a groove by detecting the arc voltage during-low-power, small-welding pool mode to surely form a weld zone between parts having small weld joint width. SOLUTION: The pilot arc voltage is detected by an AVC detector 26. The detector outputs the signal proportional to the pilot arc voltage to a time-delay AVC control device 28. The device 28 controls an AVC driving device 20 as the function of the pilot arc length determined by the pilot arc voltage, and the arc length is kept constant, and the primary arc length following thereto is kept. The control signal to the AVC driving device 20 is delayed to compensate the deviation (offset) between the position of a welding electrode and the position of a pilot electrode.
