Title: System for switching gas in bottom blown converter
Inventor: MORI ATSUSHI
IPC: C21C5/48
Filed: 1982-04-22
Abstract: PURPOSE:To maintain the flow rates of the supply gases in the inside and outside pipes of the tuyere of a converter by throttling the gases to be supplied to the inside and outside pipes on generation of a switching command, flowing the supply gases to be switched to the respective pipes and controlling the flow rate thereof then stopping the supply of the above-described preceding gases. CONSTITUTION:The supply of gases from the 1st pipeline to the 2nd pipeline for an inside pipe 7 and from the 3rd pipeline to the 4th pipeline for an outside pipe 6 is changed over respectively among the 1st and the 2nd pipelines communicating with the inside pipe 7 of the above-described tuyere 8 and the 3rd and the 4th pipelines communicating with the outside pipe 6. The shut-off valves 4D, 4B of the 2nd and the 4th pipelines are opened to start flowing of the 2nd and the 4th gases D, B respectively upon incoming of a switching command. When the opening of the valves 4D, 4B is finished, the set values for controlling the respective flow rates of the 1st and the 3rd gases C, A in the 1st and the 3rd pipelines are stepped down simultaneously. If there is no abnormality after a specified time, the valves 4C, 4D in the 1st and the 3rd pipelines are closed and the automatic control for controlling the respective flow rates of the gases D, B for the 2nd and the 4th pipelines is started and the switching of the gases is completed.

Title: Precision die forging method
Inventor: KONDOU KAZUYOSHI
IPC: B21K1/30
Filed: 1980-05-21
Abstract: PURPOSE:To perfectly fill material into dies with less pressing force by interrupting the working stroke on the way of pressing, opening a hole in the semiprocessed goods then performing pressing again, in closed die forging. CONSTITUTION:When an example is taken of working of a spur gear, forging is carried out by a punch 1 having teeth parts on the outside circumference and a closed type die 2 accepting this. A disc blank material 3 of a diameter close to a dedendum circle is put in the die 2, and is worked by lowering the punch 1. When screwed down, the material 3 flows outward and gradually fills the die until the filling does no longer progress and the working force increases sharply. Here, the screw-down is stopped, and while an unfilled part 5 is kept to exist, the semiprocessed good is taken out and a suitable hole 7 is opened in the center. This is put into the die 2, and again screw-down is carried out. Then, the material 3 flows to the inner side of the hole, and produces outward flow as well, so that the final filling of the material 3 into the die is completed under low load and precision casting is accomplished.

Title: Manufacture of die bonding sheet and semiconductor chip securing carrier
Inventor: AKATA YUZO
IPC: H01L21/58
Filed: 1990-03-16
Abstract: PURPOSE:To make adhesion between a support base and an adhesive layer adjustable by providing an adhesive layer for die bonding over a thermally formable tacky layer prepared on a support base. CONSTITUTION:A thermally formable tacky layer 2 is prepared on a support base 1, and an adhesive layer 3 for die bonding is prepared thereon. When a wafer is diced into small pieces of semiconductor elements, the adhesive layer 3 for die bonding directly adheres to the wafer to serve as a wafer support, and when a semiconductor chip is mounted, it functions as a chip carrier and an adhesive layer for the semiconductor chip. The thermally foamable tacky layer 2 is positioned between the support base 1 and the adhesive layer 3 for die bonding, and when the wafer is diced, it couples them firmly, secures the wafer, prevents chips from scattering, and subsequently foams thermally to cause lowering of adhesion between the adhesive layers. This makes the adhesion between the support base 1 and the adhesive layer 3 adjustable.

Title: Focus and iris adjusting device
Inventor: YAMASHITA TOSHIHIRO
IPC: H04N5/238
Filed: 1990-03-16
Abstract: PURPOSE:To set up a focus and an iris respectively to optimum states by successively differentiating all the picture elements of gradation image data to calculate the differential values of the image, integrating the differential values and adjusting the focus and the iris so that the integrated value is maximized. CONSTITUTION:A CPU 5 measures the size of a specified scanning range and decides whether the measured value exceeds a prescribed value or not. When the measured value is less than the prescribed value, a mask area 30 is selected, and in the case of the measured value more than the prescribed value, a mask area 31 is selected. A focus adjusting motor 12 is driven, and while gradually changing the fucus over the whole range, image pickup operation is executed. Consequently, the CPU 5 successively calculates the differential value integrated value in each adjusting position of the iris and detects the maximum value of respective integrated values. When the maximum value is detected, an iris adjusting motor 13 is driven and fixes an iris adjusting mechanism on an iris position for applying the maximum value. Thus, the focus and the iris can be set up to the optimum states.
