    摘要： A tilt control apparatus includes an orthogonal shift detector (9) which detects an orthogonal shift by comparing a pair of a plurality of tap coefficients (C1, . . . , C7) of a FIR filter and generates an orthogonal shift signal, and an actuator varies the inclination of the optical axis of the light beam to correct the orthogonal shift, and a tilt controller (10) controls the drive of the actuator in accordance with the orhogonal shift signal to minimize the orthogonal shift. In the information recording operation, the orthogonal shift obtained based on a recording track is previously stored in a temporary storage portion and the stored orthogonal shift is used to conduct the tilt control.

    摘要： A recording/producing device for writing data on a recording medium, or reading data from the recording medium, wherein data matching a recording pattern so specified as to include a plurality of mutually different sets of mark lengths and space lengths is written on the recording medium, and the data is then read to generate data signals. An edge shift detector uses data signals to measure the edge shift amount of a mark formed on a recording medium for each set of a mark length and a space length. A record controller sets a recording parameter for each set of a mark length and a space length based on the measured edge shift amount.

    摘要： The front and rear surfaces of plates to be butt-welded are slidably held by front and rear backing shoes, respectively, for defining a welding space in a narrow groove formed by the edges of the plates, and the edges are melted by a plasma arc generating torch, while a plurality of consumable electrodes are fed into the welding space are molten by arcs generated therebetween. The backing shoes, the torch, and the consumable electrodes are moved along the groove to obtain a butt-weld of high quality at high efficiency. In addition, the electrode of the torch has an elongated configuration in section at its end portion, and its restraining nozzle surrounding the electrode has a nozzle opening which also has an elongated configuration in correspondence to the end portion of the electrode. The longitudinal axes of these configurations are aligned with each other to effectively utilize the energy of a plasma arc generated by the torch.
