摘要： The method of the present invention comprises detecting a recording pattern, which is different for each tract, in each of track groups consisting of a predetermined number N or tracks recorded in advance on an optical disk(1), generating a tracking signal S.sub.ET whose signal level changes on the positive and negative sides of a target track T.sub.0 as the center, and moving the optical spot to the target track T.sub.0 on the basis of this tracking signal S.sub.ET. In this manner, it becomes possible to prevent uncontrollable movement of the optical spot and align the optical spot to a desired recording track within a short period of time.

摘要： A tracking servo system in a recordable optical disk player apparatus utilizes clock signals to be produced by irradiating laser beam to clock pits in servo areas as a reference signal for on-track adjustment. Based on the clock signal, polarity of a tracking error signal is detected for selectively opening and closing servo loop of the tracking servo system. CLOSED LOOP on-track adjustment will be performed while a laser beam spot is in a range where the tracking error indicative value is gradually reduced according to decreasing of the distance of the laser beam spot to the track center. On the other hand, OPEN LOOP on-track adjustment will be performed while the laser beam spot is in a range where the tracking error indicative value is increased according to decreasing of the distance between the laser beam spot and the track center. Since the polarity of the tracking error signal may indicate the range of the laser beam spot position, selection of the CLOSED LOOP and OPEN LOOP can be made without requiring the signal to be reproduced from the data area. :

摘要： A second harmonic generating element radiates a laser beam having a wavelength of 532 nm onto a substrate surface. The laser beam corresponds to the second harmonic beam of a fundamental laser beam having a wavelength of 1064 nm. An emitting optical system emits the laser beam vertically to the substrate surface so that the laser beam is made linear. An observing means has a optical axis Lo oriented in a different direction from a optical axis Li of the emitting optical system and provides a CCD image sensor served as a two-dimensional imaging device located in conjugation with the height or thickness of the substrate surface. The observing means operates to observe a light section image formed by the linear beam fired by the emitting optical system onto the substrate surface. Then, an image processing means precisely measures the form of the surface of an object to be measured as suppressing degrade of an S/N ratio, on the basis of the image data of the light section image observed by the observing means.

摘要： A control circuit for an inverter for converting DC voltage to AC voltage, operable in an individual mode and an interconnection mode, and including a synchronous compensating circuit in which, when the inverter is operating in a power system synchronous operation mode under control of a synchronous-interconnection control system, a quantity of an instantaneous voltage variation component occurring in the power system is separated, in order to detect respectively, a quantity of the variation of the component in same phase with a reference voltage vector of the output voltage of the inverter, and a quantity of the variation of the component orthogonal to the reference voltage vector. The detected variation quantities are respectively added to the outputs of a voltage adjuster and a phase adjuster in the synchronous-interconnection control system. The circuit is capable of compensating an instantaneous variation of the power system without a decrease of circuit stability.

摘要： In an image projection on a screen, an image projection apparatus improves the safety of entry into a projection region by the human body and does not bring about the increase of complexity of the configuration thereof owing to the improvement of the safety. A monitoring area is regulated on the outside of the projection area (3) of the screen (2). A detection wave such as infrared rays is emitted from a detection wave source (1c) of the image projection apparatus (1). A reflection wave from the monitoring area is detected by reflection wave detection means (1d) such as a CCD sensor. Whether the human body or an obstacle enters the monitoring space, which is surrounded by a detection wave (4) between the main body unit of the image projection apparatus (1) and the screen (2), or not is detected. Once the entry is detected, the intensity of the radiation light traveling toward the projection area (3) is reduced or cut off according to the situation or the degree of the entry.
