Title: Heat exchanging method and heat exchanger
Inventor: BURANISURAFU KORENITSUKU
IPC: F28D5/02
Filed: 1996-04-22
Abstract: PROBLEM TO BE SOLVED: To provide a positive pressure heat exchange apparatus having a compact structure by utilizing the phenomena of sensible heat exchange and evaporating heat exchange. SOLUTION: A heat exchange apparatus 10 is provided with a direct evaporative heat exchange section 90 overlying an indirect evaporative heat exchange section 50. An air entry zone 120 common to both heat exchange sections receives an air stream blown into this zone by a fan, thereby pressurizing the plenum such that the air stream is forced to split and enter each section inside the apparatus. This eliminates the need for separate air entries, thus reducing the size and cost of the apparatus, while increasing heat exchange capacity. A countercurrent airflow pattern through the direct evaporative heat exchange section 90 provides a uniformly cooled evaporative liquid for use in the indirect evaporative heat exchange section 50. The evaporative liquid flow is parallel to the air stream provided in the indirect evaporative heat exchange section 50.  A process fluid inside the indirect evaporative heat exchange section 50 can accept or reject heat from the evaporative liquid received from the direct evaporative heat exchange section 90. The evaporative liquid is collected in a sump and then pumped upwardly by a pump 32 for re-distribution.

Title: Magnetic head
Inventor: MAEDA MASATAKA
IPC: G11B5/23
Filed: 1987-04-22
Abstract: PURPOSE:To decrease an ineffective magnetic flux and to speed up a recording current and a reproducing signal by providing a conductive material to cover a gap at least at a part excluding a side surface opposite to a recording medium. CONSTITUTION:At the side surface and rear surface of a gap 4, a conductive material 6 to cover a gap is bonded. When a gap side surface magnetic flux 7 flows at the conductive material 6, an eddy current 8 flows in the direction to disturb the change of the side surface magnetic flux 7 at the same conductive material 6, the side surface magnetic flux 7 is reduced, comes to be the recording effective magnetic flux and even the gap rear surface magnetic flux is decreased in the same way by the effect of the eddy current. When the eddy current 8 flows at the conductive material 6, a magnetic flux 9 generated by the eddy current 8 itself passes trough the section between the gaps 4, comes to be a recording effective magnetic flux, passes through a coil 3 through a magnetic core 2, and thus, the inductance of the magnetic head 1 itself is lowered. Thus, an ineffective magnetic flux is decreased, the recording reproducing efficiency can be improved and to speed up the recording current and the reproducing signal can be executed.

Title: Production of titanium alloy
Inventor: ARIYASU NOZOMI
IPC: C22F1/18
Filed: 1995-03-30
Abstract: PURPOSE: To eliminate the dispersion of fracture toughness value due to a difference in draft in a forged product and to improve homogeneity in strength by performing prescribed finish forging in a β-phase region and then rapid cooling, at the time of producing a forged product of near beta titanium alloy with complicated shape. CONSTITUTION: At the time of forging, finish forging is carried out at 30-50% draft in the β-phase region higher by 30 deg.C than β-transus temp., followed by rapid cooling. As compared with an alpha plus beta alloy, a near beta titanium alloy has large beta crystalline grain size and the degree of flatness of the crystalline grain is greatly changed with the change in finish draft. Simultaneously, with the increase in draft, the degree of flatness in increased and also the beta crystalline grain boundaries being flat in a direction perpendicular to working direction have continuity and α-phases are liable to precipitate.  Accordingly, in this treatment, finish forging draft is limited in order to refine crystalline grains and also to inhibit the precipitation and growth of the α-phases precipitated in grain boundaries, and further, rapid cooling is carried out from the temp. after forging.

Abstract: PURPOSE:To obtain an inexpensive set value switching circuit of simple circuit constitution which operates precisely and stably by including an oscillation means which outputs a pulse signal, a counting means, a signal converting means, a selecting means, and a filter means. CONSTITUTION:Output signals of comparators 34, 36, and 38 shown in figures C-E are inputted to a multiplexer 46.

For example, when the selection signals SA-SC go up to a level 'H' and the output signals of the comparators 34, 36, and 38 are selected, outputs of the low-pass filters 48 are as shown in figures F-H. Therefore, levels of the output signals of the low-pass filter 48 are proportional to numerals set by digital numeral setters 40, 42, and 44.
