Abstract: A protruding rail portion is formed in the slider in a specific width. The core assembly in the specific width is fixed at the trailing side of the protruding rail portion. The ABS surface is formed in the specific width by the protruding rail portion and the core assembly. Since the ABS surface on the trailing side is formed only by the core assembly, the wear resistance is high and wearing is even. The assembling of the core assembly is simple because the core assembly can be set from the side direction of the slider.

Abstract: A magnetic unit according to the present invention has a recess formed in a plate which is capable of accomodating terminals, FPC and conductive joining member, thus preventing the terminals, the conductive joining member, and the like from projecting out in the direction of thickness of a magnetic head, and consistently preventing short circuits in the terminal portion from occuring by preventing contact of the terminals and a base, as well as allowing thinner magnetic head units and FDDs to be produced. A ground circuit pattern portion formed on the FPC and the core are directly connected, such that even when a carriage having a gimbal plate mounted thereto is formed from a metal, no insulating sheets are required, which allows grounding of a magnetic core to be appropriately carried out at an electrical potential different from that of a chassis.

Abstract: In a control apparatus for automobile air-conditioners including a variable displacement compressor and a fast idling device, the operation of the fast idling device is retarded until a predetermined discharge pressure of the variable displacement compressor is detected by a pressure sensor. With this retarded operation, it is possible to prevent the engine from rotating at an undue speed when the engine is operating under the fast idling mode.

Abstract: A method of mounting a magnetic head to a case employs a jig having a grooved placing unit for placing the head and a support for the case formed at a predetermined height from the slidably contacting surface of the head. The method includes placing the slidably contacting surface of the head on the bottom of the placing unit of the jig to position the head in the placing unit, placing the case on the support to set its height at a predetermined gap with respect to the mounting surface of the head, and filling a bonding agent in the gap between the mounting surfaces of the case and the head.

The connecting holes of each tube element are provided at one end of the tube element and the connecting holes in the tank element are formed in one face of the tank element. With this construction, the single tank element can commonly be used for all of the plural tube elements.

Abstract: A magnetic head assembly comprises a carriage on which a first magnetic head is mounted for performing read/write with respect to one face of a disk, a second magnetic head also mounted on the carriage opposite to the first magnetic head for performing read/write with respect to the other face of the disk, and a hold case coupled turnably via a leaf hinge spring to the carriage, wherein the first magnetic head is attached via a gimbal spring to the carriage, and the second magnetic head is secured to the hold case, and is characterized in that the carriage has a support portion abutting directly on the hold case inclusive of the leaf hinge spring to support the same, so that the hold case is supported turnably with the support portion serving as a supporting point, whereby the reference plane of the hold case is defined by the support portion, so that accuracy can be ensured for the reference plane of the second magnetic head with respect to the disk and an enhancement of the follow-up performance can contrib

Abstract: A laminated heat exchanger includes a plurality of parallel spaced tube elements with tanks at one end thereof, and fins disposed between adjacent tube elements. Each tube element has a pair of joint portions projecting from the other end thereof toward two adjacent tube elements and held in abutment with the joint portions of the two adjacent tube elements. The joint portion has a corrugated shape composed of alternate parallel grooves and ridges and hence is rigid enough to withstand external forces. The tube element includes a guide member disposed on a front end of the partition wall for directing a heat transferring medium toward the opposite corners of a guide channel. With the guide member, the heat transferring medium is distributed uniformly over the entire region of the guide channel.

Abstract: A cooling unit for an automotive air-conditioning system, comprising an evaporator, a compressor, an expansion valve connected to the inlet port of the evaporator, an accumulator connected to the outlet port of the evaporator, a temperature sensor for detecting the temperature of the refrigerant at the outlet port or within the evaporator, and temperature control means which controls the degree of opening of the expansion valve so that the temperature of the refrigerant at the outlet port or within the evaporator is maintained above a predetermined temperature which is slightly higher than a temperature at which the evaporator becomes frosted. The degree of opening of the expansion valve is increased to raise the vapor pressure of the refrigerant in the evaporator, instead of stopping the compressor, when the temperature of the refrigerant at the outlet port or within the evaporator drops to the predetermined temperature, so that the frequency of starting and stopping the compressor is reduced.

The upper case assembly includes a plurality of leaf hinge springs extending to the vicinity of the upper magnetic head, which is bonded to a supporting plate, and wire leads from the magnetic head are soldered to the leaf hinge spring ends as lead terminals.

Abstract: An air conditioning system for automotive vehicles wherein the temperature and pressure of refrigerant at the outlet of the evaporator are detected, respectively, by a temperature sensor and a pressure sensor, and the flow rate of refrigerant within the refrigerating cycle is controlled to proper values corresponding to thermal load on the system, by controlling the opening of an expansion valve with a valve control means responsive to output signals from the above sensors. The pressure of refrigerant detected by the pressure sensor is converted by conversion means into a corresponding saturation temperature of the refrigerant. Determining means determines whether or not the refrigerant quantity is insufficient by comparing the difference between the refrigerant temperature and the corresponding saturation temperature of the refrigerant with a predetermined reference value. Indicator means indicates abnormality when the refrigerant quantity is determined to be insufficient.

The cores can be assembled more readily on the leaf spring than on the holder case, thus facilitating the assembly process and miniaturization of the magnetic head.
