Abstract: This invention relates to a recording medium (10) in which one sector (S0, S1,...) is divided into a plurality of segments and information is recorded in the segments, and to a reproducing method in which information is reproduced optically from this medium (10). The recording medium (10) has an area in which no embossed pit is formed beforehand comprising at least one segment (2, 4) among a plurality of segments (1, 2, 3, 4) and embossed pits (5, 6, 7) indicative of the head of the sector (S0, S1,...) which is formed in correspondence to the head position of the sector. Clocks are reproduced by detecting the pit for clock reproduction on the basis of the area in the recording medium (10) in which no embossed pit is formed beforehand. The head position of the sector is detected by detecting whether the pit indicative of the head of the sector is present or not at a timing based on the clock. With this method, the head position of the sector can be detected correctly even if information was recorded by modulating system which does not have a signal pattern which is impossible on modulating rule.

Abstract: Diffusion-alloying techniques are used to introduce low quantities of powdered metal additives into hot-worked Nd-Fe-B magnets. The powdered metal is added to rapidly solidified ribbons of the magnetic alloy prior to hot working. Diffusion-alloying during hot-working permits the final chemistry of the magnet and more specifically the grain boundaries to be determined during the final processing steps. Elements which diffuse into the matrix, such as zinc, copper and nickel, enhance the coercivity by as much as 100 percent in die-upset magnets. At optimum levels, approximately 0.5-0.8 weight percent, the metal additives do not diminish the remanence or energy product of the magnet.

Abstract: A system for providing stable tape-travel in a recording and/or reproducing apparatus includes a tape travel-direction switching mechanism and a tape tension regulating mechanism. The tape travel-direction switching mechanism forces a pendulum gear to engage one of a supply or take-up reel table when the traveling direction of tape is switched between forward and reverse directions so as to prevent the occurrence of slack in the tape. The tape tension regulating mechanism takes up the slack in the tape before a capstan axle causes the tape to travel in the reverse direction, so as to prevent the tape from being loosened when the traveling direction of the tape is switched from the forward direction to the reverse direction.

Abstract: The use of alternating n and p type regions asymmetrically spaced in a semiconductor material yields extremely advantageous properties. In particular, by controlling the doping level and the spatial configuration of the doped region both the device response and its optical properties are controllable. Therefore, in applications such as those involving optical switches LEDs, lasers and long wavelength detectors, both the speed of device and its optical properties are controllable. As a result, greater fabrication flexibility than previously available is possible.

Abstract: A switching power supply apparatus includes a high frequency switching power supply circuit (1) supplied with a direct current voltage from a direct current power source (E). Switching elements (S1, S2) included in the high frequency switching power supply circuit alternately become conductive in response to a control pulse, whereby high frequency power is generated. The high frequency power is transferred through an isolation barrier (45) formed of capacitors (C1, C2) to a frequency converting circuit (7) wherein the high frequency power is frequency-converted into direct current power and then supplied to a load circuit (4). Accordingly, a conventionally used transformer is not required, so that no iron loss nor copper loss is generated in a isolation circuit (20), which allows the apparatus to be made more compact and lighter.

Abstract: This invention relates to a high pressure sealed window assembly (36) which does not result in substantial shear forces being applied to the window (38), and in particular to such a window assembly (36) for transmitting ultraviolet light in high pressure chromatographic detectors. The window (38) has opposed surfaces (46,48) through which light is transmitted and angled surfaces (50,52) extending toward each other from corresponding points on the outer edge of the opposed surfaces. Sealing rings (40,42), preferably shaped to conform to the shape of the angled surfaces (50, 52) bear against such surfaces and precompressed forces are applied through the sealing rings to precompress the window (38), preferably over substantially its entire volume. When pressure is applied to one face of the window, the precompression forces must be overcome before such pressure can result in shear forces being developed in the window (38). Thus, by sufficiently precompressing the window, shear stresses can either be eliminated or reduced to a level which does not pose a danger to the window (38).

Abstract: An information reading device for an optical disk has a peak level detector (1), a coupling capacitor (2), a comparator (4), and a resetting circuit (5, 6, 7, 8). The comparator (4) produces an on-track signal based on a detected peak signal from the peak level detector (1). Information tracks on the optical disk are searched based on a count of pulses of the on-track signal. The resetting circuit (5, 6, 7, 8) has a boundary detector (5, 6) and a switching circuit (7, 8). The boundary detector produces a boundary signal indicative of the boundary between recorded and unrecorded regions on the optical disk. In response to the boundary signal, the switching circuit (7, 8) discharges stored charges of the coupling capacitor (2) in the unrecorded region, causing detected peak signals in the recorded and unrecorded region to vary in amplitude across a common reference level.
