Title: Nozzle device for spinning pitch fiber which is precursor of carbon fiber
Inventor: SHIYOUNO HIROAKI
IPC: D01F6/00
Filed: 1984-04-13
Abstract: PURPOSE:To prevent the drift of the molten pitch toward the adjacent nozzle hole, and to enable high-temperature spinning of molten pitch having low viscosity, by protruding the nozzle from the spinning surface of the nozzle plate. CONSTITUTION:Each nozzle 3 is protruded 0.7-6.5mm. from the spinning surface of the nozzle plate. The molten pitch transferred through the path 5 and the nozzle hole 4 is extruded from the nozzle 3 to the outer atmosphere, and is drawn to obtain a fiber. Even if the molten pitch is subjected to the surface tension at the tip of the nozzle 3, the force is not too large to drift the molten pitch upward along the outer surface of the nozzle plate.

Title: Lens system with light shielding plate
Inventor: ORINO TATEKI
IPC: G02B27/00
Filed: 1990-03-24
Abstract: PURPOSE:To obtain high optical performance over the picture plane by arranging plural light shielding plates which have light shielding parts in specific shapes at specific positions of a lens system, reducing the light shielding quantity of on-axis luminous flux, and cutting off the spherically segmental marginal luminous flux of the off-axis luminous flux effectively. CONSTITUTION:Each light shielding plate 2 is constituted by arranging triangular light shield parts 1 radially at equal intervals from the peripheral part of a ring-shaped member 2a toward the center 0 of the circle. Then the light shielding plates 2a - 2c are arranged so that they are observed as if respective light shielding plates 1 were put one over another like one light shielding plate when viewed from the incidence-side front surface of a photography system to decrease the light shielding quantity of the on-axis luminous flux and so that much spherically segmental marginal luminous flux is cut off effectively when the entrance pupil of the lens system is viewed at the largest field angle. Thus, the constitution of the light shielding plates arranged at part of the lens system is set properly to cut off the object spherical segmental marginal luminous flux, thereby obtaining the high optical performance over the entire picture plane.

Title: Communication controller
Inventor: MURATA ICHIRO
IPC: H04L29/08
Filed: 1989-03-29
Abstract: PURPOSE:To avoid overflow of queuing means with a limited storage capacity and to keep the busy state to a minimum value by controlling a threshold level to generate/release the busy state variably in response to the state of a link and a frame. CONSTITUTION:A threshold level is increased or decreased in response to the link multiple factor every time a link is set or released after the initial set of a busy production threshold level. Moreover, when an information frame is sent or received, the busy production threshold level is increased or decreased in response to the length of the information field. Thus, the possibility of overflow of a reply frame output queue 24 is precluded, the reset processing number of times to the overflow of the reply frame output queue 24 is decreased and the busy state to the reply frame output queue 24 is minimized to extend the frame receptible period to the utmost.

Abstract: PURPOSE:To provide the title apparatus having a simple structure, requiring no strict adjustment of an optical system and obtaining high measuring accuracy by forming the reflected image of the target projected on the retina on the two-dimensional detection element of a detection means and binarizing said image by a processing means to reduce information content before operating the same by an operation means. CONSTITUTION:The luminous flux emitted from a light source is projected on the retina Er and the reflected light thereof is reflected by a perforated mirror 4 to be incident to a wedge prism 8 as six luminous fluxes by a six-perforation iris 6 and formed into images on a two-dimensional sensor array 9 at the time of the examination of emmetropia. These formed target images are sent to an image monitor 16 as video signals by a sensor driving circuit 10 and, at the same time, said signals are compared with the threshold value set by an MPU 14 and a D/A converter 15 by a comparator 11 and binarized to be stored in a memory 13 through a memory writing controller 12. The MPU operates the interval between dot images on the basis of the binarized data of the stored target images and the eye refractivity in the corresponding longitude line direction. By this method, the structure of the apparatus becomes relatively simple by the use of a two-dimensional detection element as a detection means and, further, position data utilizable in operational processing are obtained in large quantities and measuring accuracy is not deteriorated.

Title: Method for subjecting steel plate to controlled cooling
Inventor: KIMURA MOTOMU
IPC: C21D9/573
Filed: 1984-04-16
Abstract: PURPOSE:To inhibit the occurrence of defects in shape without hindering improvement in mechanical properties by reducing the amount of cooling water at the time when a specified temp. is attained in case where the cooling finishing temp. is set at <=500 deg.C and it is difficult to maintain stability in shape by a conventional method. CONSTITUTION:When a hot rolled steel plate in a hot state is cooled to <=500 deg.C, the occurrence of defects in shape is increased. In order to prevent the increase, at the time when the average temp. of the steel plate in the direction of the thickness drops to 550-500 deg.C, the amount of cooling water is reduced to 80- 50% of the initial amount. By such a very simple means as reduction in the amount of cooling water, the occurrence of defects in shape is inhibited while maintaining a satisfactory rate of increase in strength.

Abstract: The invention solves the problem of pattern recognition in a temporal signal that is subject to distortions and time warp. The arrangement embodying the invention comprises a neural network, an input interconnection network, and a plurality of signal modification circuits. A plurality of input leads delivers a preselected characteristic stimulus to associated signal modification units, and in response to an applied stimulus, each signal modification unit develops a plurality of output signals that begins at the time of stimulus application, rises to a peak, and decays thereafter. The mean time delay of each output (time to reach the peak) is different for each of the modification unit output signals. The outputs of the signal modification units are applied to the input interconnection unit wherein connections are made in accordance with the sequences that are to be recognized.
