Patent EP-0357049-A2 (EP)
Inventor: FURUTANI TADASHIGE
IPC: G11B27/30
Filed: 1989-08-30
Abstract: An information recording medium such as an optical recording medium or an optical disk comprises a first defect managing region into which an initial defective region is registered; and a second defect managing region into which a defective region occurring after the registration of the initial defective region into the first defect managing region is registered. In a recording and reproducing apparatus operating on such an information recording medium, identification information is reproduced from each of sectors in the first and second defect managing regions, the identification information representing whether the sector belongs to the first defect managing region or the second defect managing region. Defect managing information is recorded into and erased from each of the sectors in accordance with the reproduced identification information.

Abstract: The described embodiment of the present invention utilizes the regular nature of a large number of arrays by providing a grid scheme In the array to provide a low impedance point to point interconnection. In the described embodiment of the present invention a DRAM includes a number of leads (52, 54, 56) running perpendicular to the sense amplifier (30, 32, 34, 36) layout. For a given signal, each lead is interconnected to a bus lead (52) running parallel to the layout of the sense amplifiers. Thus each lead in the parallel array carries a portion of the current. In addition, in this scheme it can be assured that a substantial number of leads will be near any particular sense amplifier which is drawing on the signal provided on the grid array scheme. Because of the close proximity of the parallel conductors, the bus lines to the sense amplifiers need not be as wide as feeder lines in the prior art. Because the parallel grid leads and the bus leads may be much smaller than the leads in the prior art, they may be more compactly arranged in the array.

Abstract: A device for detecting a quantity of remaining ink includes first and second electrodes (1, 2) provided in an ink supply passage (6) which connects an ink tank (8) for storing an ink to a recording head (9) for emitting the ink, and a detection means for detecting a resistance between the first and second electrodes  (1, 2). The second electrode (2) is provided in the ink supply passage (6) in an area relatively close to the recording head (9), whereas the first electrode (1) is provided in the ink supply passage in an area relatively far from the recording head with the second electrode therebetween. The second electrode is maintained at the same potential as that of a substrate which constitutes the recording head and on which emission energy generating elements driven to emit the ink are disposed, whereas the first electrode is maintained at a potential different from that of the second electrode. IN consequence, the amount of remaining ink can be detected by measuring changes in the resistance between the first and second electrodes (1, 2).

Abstract: The deburring of plastic workpieces, in particular thermosetting fibre composites, has hitherto been carried out mainly by means of manually guided vibratory grinders which have an abrasive belt as a deburring tool. In particular in order to improve the efficiency and with regard to the desired automation of deburring operations, it is proposed that the abrasive belt (10a), which can be drawn off from a supply roller (10), be partly supported on a pressure shoe (1), and that the supply roller (10) as well as the flexibly mounted pressure shoe be attached to a supporting part (4). Behind the working area (1b) of the abrasive belt - as viewed in the direction of its draw-off movement (arrow 18) from the supply roller - the supporting part (4) is equipped with a stepping mechanism (8) which also exerts a clamping action and via which the abrasive belt can be drawn off section by section from the supply roller and, replacing the used belt section, can be guided subsequently into the working area. <IMAGE>

Abstract: A high voltage regulator circuit for maintaining the ultor voltage applied to a picture tube of a television receiver apparatus provides an auxiliary voltage signal for compensation of variations in the ultor voltage caused by variations in the beam current. An improved phase control circuit controls the phase position of the pulses of the auxiliary voltage signal so that they lag with only the leading parts thereof overlapping the retrace voltage signal pulses, in order to prevent the introduction of fluctuations in the ultor voltage due to secondary ringing. The phase control circuit includes a sawtooth waveform generator which generates a sawtooth signal corresponding to the retrace pulses, a reference voltage generator which generates a reference voltage corresponding to the ultor voltage, a comparator for comparing the sawtooth signal to the reference voltage, and a one-shot multivibrator circuit responsive to the comparator output for generating a pulse signal for the auxiliary pulses lagging in phase to the retrace pulses.

Abstract: In a method of and an apparatus for manufacturing a glass fiber mat (19), bundles of glass fibers shake down onto a conveyor unit arranged horizontally (10), to form a non-oriented fiber layer (13). The non-oriented fiber layer is dried by a drier (14). Bundles of uni-directional fibers are supplied onto the dried non-oriented fiber layer, by a bundle supply device (16), to laminate the uni-directional fiber layer onto the dried non-oriented fiber layer. At the laminating, the bundles of uni-directional fibers are guided (17) in parallel relation to each other at regular intervals in a widthwise direction of the conveyor unit. The uni-directional and non-oriented fiber layers, which are laminated one upon the other, are supplied to a needler (18) and are needled thereby, to form the glass fiber mat.
