Filed: 1984-09-19
Abstract: PURPOSE:To realize a head with excellent high frequency characteristic by selecting an cross angle of both side faces of a projected part of a core base as >=90 deg. so as to make the magnetic thin film thin. CONSTITUTION:A composite magnetic head consists of a recording/reproducing head 21, an erasure head 22 and an intermediate nonmagnetic substance 23. The 1st core half 24 consists of the 1st core base 30 having a projection 29 at the center of opposed side face to the magnetic gap 35 and the 1st magnetic thin film 31. Then a top angle theta2 of the projection 29 is specified in the range between 90 and 150 deg.. The similar structure is applied also to the erasure head 22. Thus, the characteristic of the magnetic thin film is attained sufficiently and chipping is prevented to make the film thickness thin. Thus, the magnetic loss based on eddy currents is suppressed to obtain a head with excellent high frequency characteristic.

Abstract: PROBLEM TO BE SOLVED: To control a coolant flow by way of an evaporator in such a mode as improving the performance of a system by using a pressure sensitive control valve operating upon detecting the input pressure or output pressure, or both the combined of a coolant in close vicinity to an evaporator. SOLUTION: A pressure sensitive control valve 39 is connected to detect the input pressure of an evaporator. Control of this valve 39 is inversely proportional to pressure in this evaporator, therefore if the detected pressure is increased, a size in an opening part in the valve is decreased, and in contrast with this, the detected pressure is decreased, the opening part in the valve is increased. In addition, a reference source 38 is connected to a pressure input port 50 of the valve 39, offering a reference pressure, and this pressure is comparable with the evaporator output pressure. This reference source 38 is good enough if it is a fixed type or a variable type, supposing that it is variable, the output pressure of thid source 38 is controllable by a lot of input data.
