Title: Analog reproduction circuit for digital data
Inventor: KISHIMOTO KAZUO
IPC: G11B20/10
Filed: 1987-10-13
Abstract: PURPOSE:To reproduce an analog signal without generating jitter by providing a buffer memory of first-in first-out system, and controlling the driving speed of a recording medium by outputting a reproducing speed control command from a speed control circuit to a servo circuit corresponding to the data storing quantity of the buffer memory. CONSTITUTION:The driving speed (reproducing speed) of the recording medium 1 is controlled positively by providing a FIFO buffer memory 14 just before a D/A conversion circuit 10 and outputting the reproducing speed control command from the speed control circuit 15 to the servo circuit 12 corresponding to the data storing quantity of the FIFO buffer memory 14. In other words, the reproducing speed is decreased as the data storing quantity of the FIFO buffer memory 14 is increased, and adversely, the reproducing speed is increased as the data storing quantity of the FIFO buffer memory 14 is decreased. Therefore, it is possible to prevent the excess or the shortage of data from being generated even when dispersion in the timing of the data reproduced from the reproducing medium 1 is generated due to the nonuniformity of rotation, etc. In such a way, reproduction without generating the jitter can be realized.

IPC: G03G15/04
Filed: 1989-10-04
Abstract: PURPOSE:To project a clear image without blotting by providing an original cover provided with an irregular reflective translucent layer on the original side and a reflecting plate on the opposite side of the original. CONSTITUTION:The platen 13 is provided with the irregular reflective translucent layer 13R, and the reflecting platen 14 is provided on the opposite side of the original 4, looking from the translucent layer 13R side, at some distance. An image 4a of the original 4 becomes a shadow 13b on the translucent layer 13R of the platen 13 with the illuminating lamp 5 but the light transmitted through the original 4 and the translucent layer 13R is reflected irregularly and becomes multi-directional light without directivity. For example, since the light 5b of the illuminating lamp 5 is transmitted through the original 4 and the platen 13, reflected by the reflecting board 14, and the shadow 13b is made to disappear, the clear image of only the image of the original 4 is projected by a lens 7 on a photosensitive material 8. Thus, a clear image can be obtained effectively with a compact and a simple mechanism which does not require a separate power source.

Abstract: PURPOSE:To make the electric power supply efficient to a load without the influence on fluctuation motion of a pendulum by fixing the fixed coil supplied with electric power to a fixed member, which can be closely opposed to a movable coil connected with a load provided to the pendulum. CONSTITUTION:Electric current flows through a driving coil 6 of a pendulum circuit 19 when a permanent magnet 11 of a pendulum 1 is situated near to a detecting coil 5 of a machine body (a electromagnetic driver) 2.

A transistor 26 is on while driving current is flowing and high frequency signals generating in an oscillating circuit 25 are supplied from an AND circuit 30, through a transistor 31, to a fixed coil 7. Induced power generates momentarily in a movable coil 12 of the pendulum 1 in front of it by mutual induction action when the current flows in this coil 7. This power is supplied to LEDs (light emitting diodes) 13a and 13b of an electrical load, and LEDs 13a and 13b emit light. The fluctuation motion of the pendulum 1 is subject to no influence because of this supplying power of noncontact.

Title: Method for naturally opening hole in molten steel well in tundish
Inventor: MAEDA MASAHIRO
IPC: B22D41/42
Filed: 1993-10-18
Abstract: PURPOSE:To eliminate the need of a highly dangerous forced hole opening work and to secure the safety by forming a recessed part on the surface exposed to the inside of a tundish in a sliding plate at the time of closing the hole in a sliding nozzle, receiving the molten steel during receiving the molten steel before starting the casting and operating the slide plate to the hole opening side after receiving a prescribed quantity of the molten steel. CONSTITUTION:At the time of receiving and holding the molten steel M from a ladle before starting the casting, the solidified shell 11 is formed in the recessed part 8 and the inner hole surface of an upper plate 4 accompanying the receive of the molten steel. Therefore, at the time of sliding and changing the slide plate 5 of the sliding nozzle 3 from the recessed part 8 to the opening hole for pouring, the solidified shell 11 formed on the inner hole surface of the upper plate 4 is deformed and broken so as to be sheared between the sliding plate 5 and the upper plate 4 by being pulled by the solidified shell 11 in the recessed part 8. At the same time of opening the hole of the sliding nozzle 3, the unsolidified molten steel 12 in the upper plate 4 is used as a flow passage of the molten steel M and the natural hole opening is attained. Therefore, as the natural hole opening is easily executed, the need of a forced hole opening work is eliminated.
