Abstract: PURPOSE:To obtain a semiconductor device with an Al electrode pad having high strength for bonding and manufacture thereof by controlling the value of physical properties of a thin-film within the predetermined shear strength range on the formation of the Al electrode pad at a time when Cu and a Cu alloy are used as a wire for bonding. CONSTITUTION:An Al electrode pad into which an impurity element is mixed is employed as an electrode pad 6, and the quality of materials of a metallic small-gage wire 8 for bonding is of Cu or a Cu alloy. Pressure force P on a break increases with the augmentation of the shear strength of a film, and saturates in a short time. In the experiment it has been proved that the form of the break is brought to a break within the film in the film having F=8kg/ mm<2> or less as a saturation point, the state of the break of an excellent break in the vicinity of the interface is brought when F exceeds 8kg/mm<2>, and a semiconductor chip is damaged by its own internal stress when F exceeds 12kg/mm<2>. Accordingly, the shear strength of the film is controlled to 8-12kg/mm<2>, thus stably ensuring the high strength of connections.

Abstract: An inter-shaft bearing in a multiple body turbo-engine having an outer first shaft and an inner second shaft comprises bearing rollers disposed between an outer ring mounted on the first shaft and an inner ring mounted on the second shaft. The first shaft and the outer ring are provided with cooperating conical surfaces, and a plurality of fly-weights are disposed between the rear face of the outer ring and a retaining nut mounted on the first shaft. Each of the fly-weights has an inclined rear face which cooperates with a conical surface of the nut so that when centrifugal action during operation of the engine causes the fly-weights to move radially outwards they are simultaneously forced axially forwards to exert a thrust on the outer ring which thus tends to restrain the bearing through the action of the cooperating conical surfaces of the outer ring and the first shaft, thereby controlling bearing play.

Abstract: PURPOSE:To provide a dehumidifier for a highly humid internal air utilizing a natural energy, by making use of block-like member cooled in contact with an outer air as a heat exchanger. CONSTITUTION:A clearance 3 is formed between a block-like member 1 with a small resistivity in contact with an outer air and a wall body 2. The block-like member 1 is cooled in night and an air inside the clearance 3 is consequentially cooled with the result of temperature difference between it and the outer air. Thus, the outer air enters into a room through the lower opening 4 of wall body 2. In reverse, an internal air flows into the clearance 3 through an upper opening 5, causing a natural ventilation to take place continuously. Upon the drop of temperature of block-like member 1 at its internal side surface below the dew point of internal air, the surface condenses a part of vapor in the clearance 3 into dews thereon and the air falling downwardly along the clearance 3 is dehumidified for its return to the room. Drops of dew drip into a water receiving trough 6 and drained outside. A fan 7 is utilized to increase the volume of air flowing into the clearance 3 if necessary, in which case a dehumidified air has its temperature elevated to a desired level by means of a heater 8 and then returned to the room.

Abstract: 2.1. Known electromagnetically actuated valve devices for controlling the connection between a hydraulic fluid source and a consumer system (inlet valve) or for controlling the pressure relief of a consumer system, have the disadvantage that they have only limited suitability for finely adjusting the consumer pressure, since they operate with a relatively large pressure drop between the inlet pressure and the consumer pressure with a large flow rate, which leads to the consumer pressure overshooting and undershooting. Other known valve devices of this type have a consumer-pressure-dependent response and therefore likewise have only limited suitability for the described purpose. The invention proposes solutions which permit fine adjustment of the consumer pressure in each consumer pressure range. 
<??>2.2. The invention proposes that the opening cross-section of an initial control valve, known per se, be made continuously adjustable by means of an actuating magnet, likewise known per se, having a flow- dependent movement characteristic; it is additionally proposed that the opening cross-section of a main valve, known per se, also be made continuously adjustable as a function of the flow, by coupling an initial control valve member in a fixed manner to a main valve member. 
<??>2.3. An advantageous area of application of the invention is for electrically controlled and/or electrically regulated motor vehicle brake systems (for example anti-lock braking systems).
