Title: Manufacture of wall surface of heat exchanger tube
Inventor: INATANI MASATOSHI
IPC: C25D3/38
Filed: 1985-03-04
Abstract: PURPOSE:To accelerate boiling heat transfer by a heat exchanger tube by forming an uneven metallic layer on the wall surface of the tube by plating so as to increase the surface area. CONSTITUTION:An uneven metallic layer is formed on the wall surface of a heat exchanger tube by plating with a plating soln. contg. an oxyethylene surfactant and low concn. chloride ions as additives. At this time, a counter electrode put in the plating soln. along the inner wall of the heat exchanger tube is made of a metal nobler than the metal for plating. In the 1st stage, the metal for plating is deposited on the counter electrode by using the wall surface of the heat exchanger tube as the anode and the counter electrode as the cathode. In the 2nd stage, the wall surface of the heat exchanger tube is plated by using the wall surface as the cathode and the counter electrode as the anode. The electric capacity in the 2nd stage is made larger than the electric capacity in the 1st stage.

Title: Optical recording device
Inventor: TERAO MOTOYASU
IPC: G11B7/135
Filed: 1993-03-03
Abstract: PURPOSE:To rewrite records many times with high quality by making a difference between the maximum inclination of light intensity of a light spot in the direction of a recording track with which a recording medium is first irradiated and the maximum inclination of light intensity of the light spot in the direction of a recording track with which the recording medium is next irradiated. CONSTITUTION:Light spots of which intensity inclination is different in before- and-after in the direction of a recording track are used. The same result is obtained by an optical system in which a shape of a condenser lens is asymmetric or by a semiconductor laser 1 in which light radiation is asymmetric. Asymmetric degree of intensity distribution of light may be changed in accordance with linear velocity of a recording medium by changing angle of a flat panel in an optical system provided with an light transmission panel which is not parallel to a disk plane, moving a cylindrical lens perpendicular to the axis in an optical system using an asymmetric cylindrical lens 14, or taking out it from the optical system completely. In this case, since temperature distribution in rewriting records is symmetric for before-and-after, shape distortion of recording spots is few, and drift of a recording film can be prevented.
