A head gimbal assembly is provided with a slider that flies above the surface of a disk, and a head for reading/writing data from/onto the surface of the disk. One or more conductive wires are connected to the head and are used to transmit data. A load beam supports the wire(s) thereon and holds the head/slider near a front end of the load beam. Each wire forms a wire loop between the head connecting point edge and the wire fixing point. A predetermined portion of each wire loop is pressed from above on the surface of the load beam, and then pushed toward the head connecting point edge, thereby plastically deforming a section between the head connecting point edge and the predetermined portion of the wire loop.

A method for fabricating a semiconductor device including a semiconductor layer structure, a source electrode and, a drain electrode formed on the semiconductor layer structure, and a source interconnection connected to the source electrode is provided. The method includes the steps of: (a) forming the semiconductor layer structure on a substrate; (b) forming a metal layer structure so as to cover the semiconductor layer structure; (c) forming a resist layer having a predetermined pattern on the metal layer structure: (d) performing a first etching process for the metal layer structure using the resist layer as a mask so as to form the source electrode, the drain electrode and the source interconnection; and (e) performing a second etching process for the semiconductor layer structure using the resist layer as a mask so as to form a transistor gap portion between the source electrode and the drain electrode. The respective first and second etching processes in the steps (d) and (e) are performed using the same resist layer as the mask in the same chamber.

When defective pixels of a solid state image pickup device of a video camera are corrected by signal processes, a white spot noise is detected by closing an iris and by comparing the signal level and a level of only a dark current. Further, in this case, a gain of an AGC circuit for controlling a gain of a video signal is raised and a precise detection is executed. By executing such a detecting operation at the time of turn-on or turn-off of a power source, the user is not annoying. In the ordinary photographing, a reference level in detection of a white spot noise is set to an optimum value in accordance with a temperature of the solid state image pickup device or its peripheral temperature or the gain of the AGC circuit so that the white spot noise detection is not influenced by the temperature of the solid state image pickup device or the operating state of the AGC circuit.

A microwave-assisted plasma processing apparatus has a reaction chamber in which a substrate holder is provided to support a substrate to be treated. The holder is formed congruent with the inside of reaction chamber and located to substantially separate a reaction space in the reaction chamber save for a narrow clearance therebetween through which exhausted gas passes from said reaction space into said auxiliary space. By this structure, high density plasmas can be formed in the reaction chamber without substantial loss of input microwave energy.

A data imprinting device of the type in which data are imprinted on the film surface during the time when the film is transported. The device includes a data exposure device positioned on the presser plate which presses the film against the film gate of the camera in fixedly secured relation at a location corresponding to the vicinity of the path of movement of the film and a prohibitor responsive to accidental interruption of the film transportation for prohibiting further imprinting of data until the next frame, which came across the data exposure making device at the time of the accidental interruption, is brought into alignment with the data exposure making means as the film transportaion has been re-started.
摘要:
A substrate having a film to be etched is coated with a carbon film. The carbon film is then coated with an organic mask. The mask is then patterned to expose portions of the carbon film. Plasma etching is then utilized to remove portions of the carbon film not covered by the mask, followed by wet etching to form a predetermined pattern in the film on the substrate.

A voltage regulator circuit for an AC generator of an automobile is disclosed. The circuit comprises, in addition to the conventional elements, a transistor turned on and off in phase with the power transistor by the control transistor of the voltage detecting circuit. The collector of this additional transistor is coupled to the positive terminal of the battery through a resistor, while the emitter thereof is grounded. A serial circuit of a resistor and a capacitor forming a positive feedback circuit is coupled across the collector of this additional transistor and the base of the control transistor, a biasing resistor being coupled across the base and emitter of the control transistor. Thus, when the control transistor is turned on, the charging current of the capacitor produces a forward bias across the base and emitter of the control transistor; when the control transistor is turned off, the discharging current of the capacitor produces a reverse bias thereacross. A Zener diode is coupled across the collector and emitter of the additional transistor to limit the voltage thereacross under a predetermined level. Thus, the capacitor in the feedback circuit is protected from voltage surges.
