摘要： A substrate 1 for growing nitride semiconductor has a first and second face and has a thermal expansion coefficient that is larger than that of the nitride semiconductor. At least n-type nitride semiconductor layers 3 to 5, an active layer 6 and p-type nitride semiconductor layers 7 to 8 are laminated to form a stack of nitride semiconductor on the first face of the substrate 1. A first bonding layer including more than one metal layer is formed on the p-type nitride semiconductor layer 8. A supporting substrate having a first and second face has a thermal expansion coefficient that is larger than that of the nitride semiconductor and is equal or smaller than that of the substrate 1 for growing nitride semiconductor. A second bonding layer including more than one metal layer is formed on the first face of the supporting substrate. The first bonding layer 9 and the second bonding layer 11 are faced with each other and, then, pressed with heat to bond together. After that, the substrate 1 for growing nitride semiconductor is removed from the stack of nitride semiconductor so that a nitride semiconductor device is provided.

摘要： The invention presents a magnetic recording and reproducing apparatus capable of reducing the size and preventing external force from propagating directly to the internal mechanism. To achieve the object, a main arm 26 and a sub-arm 29 are constituted so as not to intersect with a photo detector 31 always during rotating operation within a plane including the photo detector 31, and the dimension can be hence reduced in the width direction of the apparatus, and moreover as the wall thickness of MIC-SW 46 is reduced, the upper end of the MIC-SW 46 is held by a back plate 48, so that the dimension of the apparatus can be reduced also in the depth direction, and further a cassette holder 13 is locked by a damper 42 to prevent effects from outside when a sub-chassis 19 moves from unloading position to loading position.

摘要： An angled illumination tube is capable of reducing a dark spot behind the reflector, while illuminating the tube uniformly over the length of the tube. The tube is used in combination with a light source providing a light beam and comprises an angled transparent tubular conduit having a first end and a second end on opposite longitudinal ends of the conduit. The conduit has a bend between the first and second longitudinal ends, and is used with the first end receiving the light beam from the light source in order to guide the light beam along the length of the conduit. A reflector is disposed within the bend to reflect the light beam from the first end to direct a reflected light beam towards the second end. The reflector defines an incident light axis along which the light beam is guided to the reflector, and a reflected light axis along which the reflected light beam is directed to said second end. The reflector is composed of a plurality of mirrors arranged in a parallel array along a bisector that divides an included angle between the incident and reflected light axes at an angle (.theta.) with respect to the incident light axis. Two adjacent ones of the mirrors are spaced at a fixed distance (d) along the bisector and of uniform length (L) measured within a plane including the incident and reflected light axes. The mirrors are arranged to satisfy the following relation: ##EQU1##

摘要： A cassette loading/unloading apparatus enables a magnetic recording and reproducing device to be used with both a standard-type tape cassette and a miniature tape cassette without a cassette adapter. When the miniature tape cassette is used, a holding mechanism for the standard-type tape cassette is located at a position where it does not hinder the loading of the miniature tape cassette. When the standard-type tape cassette is used, a holding mechanism for holding the miniature tape cassette is located at a position where it does not hinder the loading of the standard-type tape cassette. Further, only one tape extraction mechanism and only one detection unit for detecting an anti-erasure claw are provided for extracting a magnetic tape from either of the standard type tape cassette and the miniature-tape cassette and for detecting the presence of the anti-erasure claw of either of the two types of tape cassettes.

摘要： A servomotor control method controls a servomotor stably at a high speed. A control loop is switched from a PI control mode to an I-p control mode by varying a gain coefficient of a proportional arithmetic unit (1). This achieves a control process having the advantages of both the PI and I-p control modes.

摘要： A speed control method for a servomotor, capable of smoothly rotating the servomotor without causing pulsating rotation even when the servomotor rotates at low speeds. On the basis of the numbers of feedback pulses (P2k(m-1)-k+1, . . . , P2km) detected and stored at intervals of a period (TS/2k) equal to a value obtained by dividing an estimated speed calculation period (TS) by an integer multiple of 2, the number (A) of feedback pulses in each estimated speed calculation period and the number (B) of pulses in a time period from a midpoint ((m-1)TS-TS/2) of an estimated speed calculation period immediately before each estimated speed calculation period to a midpoint (mTS-TS/2) of each estimated speed calculation period are calculated, and an estimated speed indicative of an actual rotation speed of the servomotor is further calculated on the basis of the thus calculated numbers (A, B) of pulses.

摘要： A reference-point return method for a numerical control system. When a return is made to a reference point, a numerical control unit (21) reads an absolute position of a motor (23) within one revolution thereof from an absolute position detector (24), obtains a distance B from a predetermined motor point (a grid point) to the absolute position that has been read, and initially sets the distance B as a command position REF.sub.n from the grid point. Thereafter, the numerical control unit (21) outputs a move command value .DELTA.R.sub.n to a digital servo-circuit (22) every predetermined time .DELTA.T, updates a commanded position REF.sub.n in accordance with the equationREF.sub.n +.DELTA.R.sub.n .fwdarw.REF.sub.nobtains REF.sub.n after a deceleration limit switch (25) is depressed, and outputs (N-REF.sub.n) to the digital servo-circuit (22) as a final commanded traveling distance .DELTA.R.sub.n to return the movable element to a reference-point position set at a predetermined grid point.

摘要： There are provided a method and an apparatus for absolute position detection, in which position detection is performed with high accuracy by interpolation between feedback pulses generated as an object of position detection moves, and the power-on command displacement can be calculated with high accuracy, the method and the apparatus entailing only small electric power consumption. A stored value in an absolute counter (2), which is indicative of an approximate absolute position of an object of position detection, is updated each time a feedback pulse is generated from a feedback pulse generating circuit (1), and is retentively stored in the counter even after the power is turned off. As the object of position detection moves, moreover, the count value of interpolation pulses, generated during the time interval which elapses from the instant that the power is turned on again until the first one of the feedback pulses is generated, is temporarily stored in a correction counter (5). The power-on absolute position of the object of position detection is calculated by means of a numerical control unit (20), in accordance with the stored value, the count value, and the moving direction designated by a movement command delivered when the power is turned on. Further, the apparatus calculates the command displacement on the basis of the calculated absolute position and a command target position.
