摘要： Separators for unit cells of a fuel cell each have a plurality of through holes extending therethrough and a recessed portion formed in a surface thereof. In a fuel cell incorporating such separators, the recessed portion of each separator forms an in-cell oxidative gas passage, together with an adjacent cathode. An oxidative gas, supplied from an external device into the fuel cell, is distributed from an oxidative gas supply manifold formed by holes of the separators, to the in-cell oxidative gas passages. The oxidative gas is then collected in an oxidative gas discharge manifold formed by holes of the separators, and conveyed out of the fuel cell by the discharge manifold. During the passage through each in-cell oxidative gas passage, the oxidative gas flows via an oxidative gas transit manifold formed by holes of the separators.

摘要： A semiconductor IC including a resistance element on a circuit substrate. The resistance element includes a resistance layer formed on an insulating layer. The resistance layer is formed using a Si layer obtained by forming an a-Si layer, doping the a-Si layer with impurities, and heating the doped a-Si layer to diffuse the impurities while substantially preserving the fineness of the a-Si layer surface. Preferably, a SiN layer is provided lying beneath the resistance layer. A capacitor may be integrated on the same circuit substrate where the resistance element is formed. In this case, a lower electrode, a SiN dielectric layer, and an upper electrode are formed in this order to constitute a capacitor. The SiN dielectric layer of the capacitor is formed extending from a capacitor formation region to another region, so that the resistance layer of the resistance element is formed on the extending SiN dielectric layer. The lower and upper electrodes of the capacitor may be formed using an a-Si layer, similar to the resistance layer.

摘要： A method of recording a servo signal on each track of a magnetic disk includes a first signal for demagnetizing the magnetic disk and a second signal for forming the servo signal. The recording width (core width) of the magnetic head is made greater than the width of the track. Parts for recording signals and not recording signals are set in each track. The first and second signals are selected and recorded in the signal recording part, thereby to form the servo signal. Current to be conducted to the magnetic head is cut in the part for not recording signals, and the track is skipped to the next part for recording signals. When the recording of the track has ended, the magnetic head is moved to the next track, and the above steps are repeated.

摘要： A head arm for use in a magnetic disk drive, comprising a guide arm disposed between a magnetic head and an actuator so as to transmit actuating force of the actuator to the magnetic head thereby guiding the magnetic head along a plane of a magnetic disk, a printed circuit fixed to the guide arm, and deflection compensating member for making the coefficients of thermal expansion of said guide arm and said printed circuit substantially equal to each other in at least the direction of seek of the head arm. No thermal deformation in an out-of-plane direction occurs on such a head arm regardless of any variation in the temperature of the environment in which the magnetic disk drive is installed. The head arm may also comprise a guide arm and a printed circuit formed of a moisture absorptive material and covered at all or part of its surfaces with a covering layer formed of a moisture resistive material not permeable to moisture. No deformation in an out-of-plane direction occurs on such a head arm regardless of any variation in the humidity of the environment in which the magnetic disk drive is installed. Therefore, the possibility of occurrence of off-track can be minimized.

摘要： An axial force exerting in the axial direction of a rotary actuator is uniformly applied to a plurality of axially arranged ball bearings of a bearing set to hold inner and outer rings of each ball bearing in optimum position, thereby heightening the rigidity of the bearing set. A waved washer is interposed between the ball bearings and distributes the axial force so as to axially slide the ball bearings. While being slidden to the optimum positions, the ball bearings are bonded for fixing.
