Title: Polarizer for infrared range
Inventor: MURAKAMI KENSUKE
IPC: G02B5/30
Filed: 1984-11-08
Abstract: PURPOSE:To obtain a polarizer which meets requirements of characteristics and cost by arranging a plate type material which has transmission characteristics in the infrared range so that the angle of incidence of infrared light is a Brewster angle. CONSTITUTION:A plate which is arranged at thetaB and a plate which is arranged at an angle varied within a range thetaB+20 deg. are used in combination. The directivity of the polarizer composed of the plural plates is the composite directivity of the plates, so the tilt angle of each plate is varied within a range thetaB+ or -20 deg. and the polarizer operates for light arriving in wide-range directions so that the directivity is made broad and the visual angle of the polarizer is increased. In another way, plates which are arranged within a range thetaB-thetaB+20 deg. are used. The tilt angle thetaB of a plate itself is set <=(thetaB+20 deg.) larger than a calculated value to reduce a decrease in polarization ability when an incident light beam deviates decreasing in angle of incidence, and the polarization ability characteristic to the angle of incidence is made flat.

Title: Method for controlling and rolling shape of sheet stock
Inventor: KITAHAMA MASANORI
IPC: B21B37/38
Filed: 1987-09-21
Abstract: PURPOSE:To correct local deformations and to prevent shape defects by predictively calculating a shape of a rolled sheet stock under a standard value of roll bending force based on a present value and the standard value of roll bending and controlling a flow rate distribution of a coolant in the roll body length direction. CONSTITUTION:A shape of a sheet stock 16 is controlled by adjusting roll bending forces based on outputs of a sheet shape detector 18. Shape defects of the stock 16 are prevented by effectively performing the shape control by roll bending forces having high responsiveness.

Therefore, a zone coolant is used so that the force Fm does not reach its mechanical high and low limits and to prevent local deformations. Further, shape defects caused by improper flow rate distribution of the zone coolant is prevented.
