Title: High corrosion resistance stainless steel
Inventor: ISHIYAMA YOSHIHIDE
IPC: G21D1/00
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To maintain high corrosion resistance over a long period even in the environment of radiant rays by forming a concentrated layer of Mo on the grain boundaries. SOLUTION: By forming a concentrated layer of Mo on the grain boundaries of stainless steel, the depletion of Cr from the grain boundaries by the irradiation of radiant rays can be suppressed, and the maintenance of its high corrosion resistance over a long period is made possible. As the Mo concentrating method into the grain boundaries, heat treatment is preferably used. Namely, stainless steel added with Mo at a certain concn. is subjected to heat treatment at 550 to 800 deg.C for >=5 min. As a result, Laves phases or (x) phases as the intermetallic compds. of Mo and Fe are precipitated into the grain boundaries.  When such precipitation occurs, its corrosion resistance is deteriorated, therefore, the concn. of Mo is considered in such a manner that the state is retained to the one in which Mo only is concentrated on the grain boundaries in the stage prior to the one in which the precipitation occurs, and the temp. and time are controlled.

Abstract: PURPOSE:To make capacity Cbc between a base and a collector small by forming the mask to decide a collector region by self-alignments of the mask to decide an emitter contact region and a mask region and the mask to decide an external base region. CONSTITUTION:An emitter contact layer 22, which contains n-type impurity, an emitter layer 23, a base layer 24, which contains p-type impurity, a collector layer 25, and a collector contact layer 26 are formed in order by film growth on a semiinsulating substrate 21, and thereon a mask 41 is formed and oxygen ions are implanted deep from the surface so as to form an insulating region 31. Subsequently, an external base layer 32 is formed, and a mask 42 is made slenderly crossing the mask 41 at right angles, and not-covered part of the mask 41 is removed by dry-etching. Subsequently, oxygen ions are implanted shallowly to the vicinity of the base layer 24 so as to form an insulating region 33. Furthermore, the mask 42 is removed, and with the residual part of the mask 41 as a third mask the vicinities of the layers 25 and 26 is removed by wet etching. Hereby, it can be made without the emitter contact region and the emitter region and the external region overlapping each other, and Cbe can be minimized in structure.

Abstract: PURPOSE:To make recovery of ink discharge function possible in malfunction of ink drop discharging, and to prevent occurrence of the malfunction in ink drop discharging by a method wherein the ink is sucked with a cap stuck to an ink drop discharging part when the pressure is applied to the ink. CONSTITUTION:With an instruction for execution of removal of air bubbles and alien substances given, a head carriage 1 moves to an ink supply position. As confirmation is made by detection that the movement is made to a specified position, a cap 223 and connecting parts 224 and 225 are pushed successively toward the head carriage 1 side, and thereby an ink drop discharge part is closed tight. With an ink supply passage connected, valving mechanism 226, 227 operate, making the valve 226 closed, and the valve 227 closed on the atmosphere side, and thereby an ink supply pump 221 and an ink discharge pump 222 operate. With the difference between the positive pressure applied by the ink supply pump 221 and the negative pressure applied by the ink discharge pump 222 given to the ink, sufficient dynamic pressure can be obtained in the flow of the ink, and thereby removal of the air bubbles and the alien substances becomes possible.

Abstract: PURPOSE:To enable smooth clutch connection by changing a flow limit degree for hydraulic fluid with an orifice fitted in the oil discharge passage of a hydraulic servo unit depending upon throttle opening in connecting the clutch. CONSTITUTION:When a clutch CL is connected with a hydraulic servo unit 130, a flow in oil discharge passages L6, L3, L9, L10 for discharging hydraulic fluid from the servo unit 130 is controlled in such a way that an orifice change valve 270 is moved left with throttle pressure from a throttle valve 240 when throttle opening is large, thereby closing the vale 270 and discharging fluid only through an orifice 274 at one side. Also, the connection speed of a main clutch CL is thereby smooth. On the other hand, when the throttle opening is small, the orifice change valve 270 is moved right and opened, thereby discharging fluid through two orifices 272 and 274, and smoothing the clutch connection. According to the aforesaid construction, smooth clutch connection can be embodied.
