Title: Crystalline fiber
Inventor: TAKAHASHI KENICHI
IPC: G02B1/02
Filed: 1982-03-16
Abstract: PURPOSE:To reduce loss at a contacting point by inserting a fiber of core crystal where infrared light is transmitted into a clad crystal pipe which has a less index of refraction than the core crystal. CONSTITUTION:The core crystal fiber 1 is inserted into the clad crystal pipe 4 to obtain a crystalline fiber having structure shown in a figure. The core crystal fiber is inserted into the pipe, so the diameter of the pipe should be greater than that of the core, but when the insertion is too loose, the pipe is drawn with a die to the extent that the core crystal fiber is not damaged and clamped. This crystalline fiber has no generation of heat even where the core crystal fiber is brought into contact with the pipe because the index of refraction of the clad crystal pipe is small and there is no loss of absorption, so this fiber is suitable to the transmission of large-output laser light and has superior infrared-ray transmission characteristics.

Title: Operation control unit of relay for controlling rotation of motor
Inventor: OGATA HARUO
IPC: H02P1/40
Filed: 1987-02-24
Abstract: PURPOSE:To permit operation control switches to be composed of semiconductors, by providing a timer circuit and an interlock circuit to a normal rotation operation control circuit and a reverse rotation operation control circuit. CONSTITUTION:When a normal rotation operation control switch A is turned ON, a timer circuit 12 outputs the normal rotation signal after the appointed time. An interlock circuit 13 gives the 'ON' signal to a solidstate relay 23 for normal rotation through an output circuit 15 when the normal rotation signal is given. At this time, interlock circuits 18 and 19 on the reverse rotation operation control circuit side will perform interlock action of reverse output and prevent the phase-to-phase short-circuit caused by turning 'ON' of a solid- state relay 24 for reverse rotation. On the other hand, if a reverse operation control switch B is turned ON in normal rotation operation, the reverse rotation signal will rise after the normal rotation signal falls by a timer circuit 17. The phase-to-phase short-circuit can thereby be prevented.

IPC: C21C5/30
Filed: 1978-04-12
Abstract: PURPOSE:To properly control blowing in operation of a pure oxygen top blowing converter with  high accuracy by modifying the temp. and component of a steel bath measured with a sublance in  consideration of prograss of refining reaction and inputting the modified values into a blowing  control model in a computer. CONSTITUTION:The component and temp. of a steel bath measured with a sublance during oxygen blowing in a converter do not represent the true component and temp. of the whole steel bath  at the measuring point of time. The representative values of the component and temp. of the  whole steel bath are values at a point of time at which blowing reaction progresses as compared  to the values measured with the sublance. The steel bath is blown more progressively in an oxygen jet firing range, and the whole steel bath is slowly subjected to decarburization, etc. with supersatd. oxygen present in molten slag and the bath. Therefore, in accordance with actual operation  results the component (C%) and temp. of the steel bath are modified with 0.85-1.0 and 1.0- 1.15 as component and temp. modifying coefficients. By inputting the resulting values in a computer as the representative values of the steel bath, oxygen blowing is controlled in the converter  with high accuracy.
