Title: Method for preventing corrosion of copper alloy tube
Inventor: SAKANISHI AKIHIRO
IPC: C23F15/00
Filed: 1991-05-17
Abstract: PURPOSE:To improve the formability of an iron film effective for preventing corrosion on the inner face of a copper alloy tube by controlling the amt. of a reducing agent soln. to be injected in accordance with the residual chlorine concn. in seawater. CONSTITUTION:Seawater is passed through a seawater duct 14, the chlorine concn. in seawater is measured by a chlorine concn. sensor 31, and the signal is sent to a controller 33 for the discharge of a fixed delivery pump 28 through a residual chlorine concn. output meter 32. When the pump 28 is turned on, a reducing agent soln. 27 corresponding to the chlorine concn. in the seawater is injected into the seawater, and the chlorine in the seawater is eliminated. When a ferrous sulfate soln. 17 is injected under these conditions, an iron film excellent in corrosion resistance is formed on the inner face of a copper alloy tube 15 since the chlorine in the seawater is eliminated at an injection point 20. The corrosion of the condenser, fuel handling machine, etc., which are inevitably supplied with chlorine in seawater, is effectively prevented by this method.

Abstract: PURPOSE:To pressurize a piezoelectric element without inserting a spacer into an outer casing, by providing a protrusion to the inside of the casing. CONSTITUTION:An impactor 7 gives an impact force to an piezoelectric element 3 by an impact energy produced by a tensioned impact spring 9 interposed by a hit metal 2, generating high-voltage current. The generated high-voltage current is taken out of a receiving metal 4. It is necessary for the hit metal 2 and the piezoelectric element 3, and the piezoelectric element 3 and the receiving metal 4 to be closely contacted to each other, in order to apply stabilized impact to the piezoelectric element 3 interposed by the hit metal 2. For this purpose, a protrusion is provided to the inside of an outer casing 1. It is abutted against the face 4 of a receiving metal 4, which is the opposite side to the face abutted against the piezoelectric element 3. Pressure is given to the piezoelectric element 3 by forcibly inserting the receiving metal 4 into the outer casing 1. With such an arrangement, the number of parts to be used and the process of work can be decreased. As a result, the cost of production for the titled generator can be decreased.

IPC: B41J33/40
Filed: 1983-06-22
Abstract: PURPOSE:To enable to easily handle or operate and control, by a method wherein the same side of an ink ribbon is repeatedly used while preliminarily feeding the ribbon by a small amount at a time to supply a fresh ribbon surface. CONSTITUTION:When a thermal head 8 reaches the right end R side or the left end L side and a printing paper 2 is fed by a one-line amount, a thermal head 8 and a driving roller 13 are retracted from a platen 1. At this moment, the ink ribbon 12 is preliminarily fed by a predetermined amount DELTAS, for example, to the left side. Namely, when printing is not conducted, the ribbon 12 is fed by the amount DELTAS independently from the reciprocal feed of the ribbon by a frictional force generated between the driving roller 13 and the printing paper 2. The preliminary ribbon feed is effected by feeding the ribbon 12, for example, to the left side by a motor and letting out the ribbon 12 from a reel B. Then, the ribbon 12 is taken up from a printable region l-r to a reel A on the take- up side by an amount DELTAS' equal to the preliminary feed amount DELTAS.
