Upwardly of the container 4, a turbine 7, a turning shaft 8 and a generator 20 are installed to function as a power generating mechanism. When the evaporating section 4a is heated (A), the work medium 11 flows upward in two phases (E) and the section 4a functions as a bubble pump. Vapor 11b of the work medium 11 flows upward through the inside of a work-medium vapor rising pipe 15 and then is introduced into the turbine 7 for generating power. After adiabatic expansion, the work-medium vapor 11b is ejected from a work-medium vapor ejecting mechanism 19a and condensed in the pipe by heating the outside of the condensing section 4c. Thus, the efficiency of the apparatus can be raised although its structure is very simple.

Title: Magnetic head
Inventor: KATO MITSUO
IPC: G11B5/127
Filed: 1986-09-22
Abstract: PURPOSE:To obtain a magnetic head with an excellent magnetic recording/ reproducing efficiency by widening the width of a magnetic metallic thin film formed to a rear joining face of the magnetic head more than the track width so as to prevent the reduction in the magnetic recording/reproducing efficiency caused by the decrease in the butted area due to insufficient accuracy at processing. CONSTITUTION:Magnetic metallic thin films 3a, 3b provided to magnetic oxide cores 1, 2 are butted at the joining face of a magnetic core half pair lower than the lower part of sliding faces 1b, 2b pressed into contact with a recording medium at a width wider than the track width TW. Since the joining faces of the corers 1, 2 sectioned by a film forming slot 7 are formed as a trapezoidal shape wider toward the lower direction, the magnetic thin films 3a, 3b formed to the rear joining face of the magnetic head have a wider area than that of the magnetic thin films 3a, 3b near a tape sliding face. Thus, the reduction in the magnetic recording/reproducing efficiency is prevented and the magnetic reluctance at the butted part is decreased. Thus, the magnetic head with the excellent magnetic recording/reproducing efficiency is obtained.
