A GMR head comprising a spin valve GMR film, which has a free layer containing a Co containing magnetic layer, and a hard magnetic biasing film for inputting a bias magnetic field to the spin valve GMR film. The hard magnetic biasing film is constituted of a film formed by laminating a hard magnetic layer on the magnetic under layer. The hard magnetic layer is disposed adjoining to edge portion of the spin valve GMR film through the magnetic under layer. The magnetic under layer has saturation magnetization Ms.sup.under which satisfies at least one condition of Ms.sup.under .gtoreq.Ms.sup.free and Ms.sup.under .gtoreq.Ms.sup.hard when saturation magnetization of the free layer is Ms.sup.free and saturation magnetization of the hard magnetic layer is Ms.sup.hard. In a MR head of this abutted junction structure, even when the track width is narrowed, occurrence of Barkhausen noise can be effectively suppressed.

A highly accurate compound-eye unit is provided, which can assemble a compound-eye lens member to a lens holder with high positional accuracy even when using the compound-eye lens member that is unsatisfactory in dimensional accuracy of an external shape. A highly accurate compound-eye unit is provided, which can assemble a light shielding member having a plurality of apertures with high positional accuracy. A distance W2 between centers of apertures AP2, AP3 is smaller than a distance W1 between optical axes of convex lens units PL2, PL3, and hence, as illustrated in FIG. 13, when a lens member IM3 is made to approach a lens holder LH along an optical-axis direction, optical surfaces or external portions of peripheral surfaces of convex lens units PL2, PL3 abut on edge portions of the apertures AP2, AP3 at two points P, Q, and a flat surface FP abuts on an abutting portion CT. At this time, the flat surface FP abuts on the abutting portion CT, whereby the lens member IM3 and the lens holder LH are positioned in the optical-axis direction. On the other hand, the optical surfaces or the peripheral surfaces of the convex lens units PL2, PL3 abut on the apertures AP2, AP3, thereby attaining the positioning in an optical-axis orthogonal direction and the positioning around a Z-axis.

摘要:
To provide a highly efficient and compact absorption refrigerating machine with water heated from 60 to 70 degrees Celsius as the heat source. In an absorption refrigerating machine including a regenerator G, condenser C, an absorber A, an evaporator E, an auxiliary regenerator GX and an auxiliary absorber AX, the concentrated solution from G is heated and further concentrated in GX, while the diluted solution from A is cooled in AX, the refrigerant vapor from GX is absorbed. A low temperature heat exchanger XL is provided for heat exchange between the concentrated solution supplied from GX to A, and the diluted solution sent from AX to G, and a high temperature heat exchanger XH is provided for heating the diluted solution leaving from XL and sent to G with the concentrated solution supplied from G to GX.
摘要:
The present invention relates to a plate heat exchanger for simultaneously exchanging heat between two sets of fluids having different temperatures. The plate heat exchanger comprises a heat exchange element (2) comprising two plates facing each other so as to form a inner sealed space as a passage for a first fluid, and a plate surface of the plate serves as a heat transfer surface, and a fluid flowing along an outer surface of the plate is a second fluid. The plate heat exchanger comprises a heat exchange element (2′) comprising two plates facing each other so as to form a inner sealed space as a passage for a third fluid, and a plate surface of the plate serves as a heat transfer surface, and a fluid flowing along an outer surface of the plate is a fourth fluid. A plurality of the heat exchange elements (2) and a plurality of the heat exchange elements (2′) are alternately disposed in such a manner that the plate surfaces of the plates are opposed to each other and a predetermined gap is formed between adjacent the heat exchange elements. A communication pipe communicating with the inner spaces of the heat exchange elements (2) and a communication pipe communicating with the inner spaces of the heat exchange elements (2′) are formed on the plate surfaces of the heat exchange elements (2) and (2′) and integrally formed with the elements.

An information processing apparatus is constructed so that a frequency of an external clock to be supplied to a central processing unit (CPU) which includes a phase locked loop (PLL) circuit is gradually increased from a first frequency to a second frequency within a latency time required for the PLL circuit to make a phase lock, when an operation mode of the CPU is switched from a first mode to a second mode.
