Title: Heat exchanger
Inventor: YOKOIE NAOSHI
IPC: F28D9/00
Filed: 1985-01-29
Abstract: PURPOSE:To provide a heat exchanger having a high heat exchange efficiency and easy to manufacture and inexpensive in cost by combining plates with fins by constituting the heat exchanger of a fluid separating parts and a counterflow part. CONSTITUTION:A fluid A enters a hollow part 14 via lead-in fins 4 in each of heat exchange elements 12, and is led out through leadout fins 5 and flows rectilinearly. A fluid B enters a heat exchange element 13 from a hollow part 17 and passes a central fin 6. Then, the fluid B is led out via a hollow part 16. As a result, fluids A and B effect heat exchange through plates 3. In this case, at the central fin 6 and a flowpath contiguous thereto is formed a counterflow shape. Further, at the lead-in fin 4, lead-out fin 5 and a flowpath contiguous thereto is formed a shape close to a directly intersecting shape. By skilfully combining the hollow part with the fin part, a heat exchanger high in the heat exchange efficiency is obtained.

IPC: H01L21/28
Filed: 1991-02-06
Abstract: PURPOSE:To prevent the decrease of acceptable elements from one semiconductor wafer, by covering a high melting point metal film of a bonding pad with a metal film whose main body is aluminum. CONSTITUTION:A bonding pad is so constituted that a titanium layer 3 as a high melting point metal layer is formed on the main surface of an insulating layer 1, and the surface of the titanium layer 3 is covered with a metal film 2 whose main body is aluminum. Hence, when a probe 4 of a probe card is brought into contact several times with the film 2, and said film 2 is shaved, electric contact can be maintained because the titanium layer 3 exists. In the case where electric tests under a plurality of kinds of test patterns are performed for one chip on a wafer, the probe 4 of the probe card can be brought into contact several times with the bonding pad, and open state or high resistance state is not caused. Thereby the decrease of acceptability from one semiconductor wafer can be prevented.

Abstract: PURPOSE:To improve the dielectric breakdown resistant voltage characteristic of an insulated electric wire by applying and baking an insulating paint on an electric conductor whose surface has undergone plasma-etching treatment to form an insulating layer thereon. CONSTITUTION:An insulated electric wire is manufactured by applying and baking an insulating paint on an electric conductor whose surface has undergone plasma- etching treatment to form an insulating layer thereon. The plasma etching treatment in this case is executed in the same manner that an etching device used for electronic circuit part manufacture or for the like has. Namely, potential difference is given between each of cylinder type or parallel plate type electrodes 3 and an electric conductor 1 being etched in a vacuum vessel 2 by electrification of the electrodes 3, and then reaction gas is introduced into the vessel to execute the etching treatment under reduced pressure. Because an irregular portion composed of ups and downs all presenting an uniform pattern is formed on the surface of the conductor by execution of the plasma etching treatment, the conductor adheres excellently to the insulating layer by applying and baking the insulating paint on the outer side of the conductor to form the insulating layer. These processes can improve the dielectric breakdown. resistant voltage of the insulated electric wire.
