Title: Dreg outlet block for electric furnace
Inventor: SOEDA TOMOMI
IPC: F27D3/14
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To obtain a dreg outlet block excellent in durability in which fusion loss of slug is suppressed. SOLUTION: Carbonic bricks are arranged on the inner wall 2 at the dreg outlet of an electric furnace and the outer circumference thereof is case of a magnesia-carbonic castable 1 to produce an integral molding. Since a uniform block is obtained while minimizing mortar joint, fusion loss of slug through the joint is eliminated and stabilized operation can be realized while substantially doubling the useful life. Furthermore, long time interruption of operation is not required for the electric furnace because brickwork is not required at site.

Title: Radiation temperature measurement
Inventor: INOUCHI TOORU
IPC: G01J5/00
Filed: 1980-05-27
Abstract: PURPOSE:To enable correct measurement of surface temperature of a matter by determining a quantity of energy radiated from the matter itself based on the emissivity of the surface to be measured obtained from the intensity of a laser beam which is emitted from a laser beam source and reflected on the surface like a mirror. CONSTITUTION:First from the intensity of a laser beam which is emitted from a laser beam source and reflected on the surface to be measured like a mirror, an emissivity of the surface is determined. Then, a cooled shielding plate is used to shield a laser beam so that a quantity of energy radiated from the surface only is measured. Thus, the temperature of the surface to be measured is obtained from both values. For example, a laser beam from a laser beam source 20 is reflected like a mirror on the surface 12 to be measured and measured with a radiation thermometer 16. It is possible to determine the emissivity of the surface from the results, quantity of energy of the source and diffused reflection factor of the surface. Then, the laser beam is shielded with a water-cooled shielding plate 18 to be measured. In this manner, the surface temperature of a matter can be measured simply at a high accuracy from the measured value and said emissivity.

Title: Testing device for printed board
Inventor: TAKADA MASASHI
IPC: G01R31/02
Filed: 1988-03-24
Abstract: PURPOSE:To prevent a printed board to be tested from being strained with the pressing force of a probe pin by pressing the head part of through-type probe pins arranged correspondingly to test points of the printed board by a scanning roller in order. CONSTITUTION:A wire driving motor 10 is operated with a command from a scanner 20 to move a roller support table 6 through a driving wire 8 as shown by an arrow X. Consequently, the scanning roller 5 moves while pressing the head parts 1a of the through-type probe pins 1 arranged on a probe panel 2 in order. Only when a pin 1 is pressed against the roller 5, its contactor 1b is projected as shown by an arrow B to contact a test point 19 of the printed board 18. When the roller 5 reaches an X-directional movement end, the motor 10 stops and a motor 13 for scanning block driving operate to move the scanning block 11 as shown by an arrow Y and position it on a next array. Then the motor 10 operates again to move the roller 5 as shown by an arrow X'. Thus, the pins 1 are operated one by one, so the pressing force operating on the printed board 18 is small.
