Title: Method for adjusting level of molten steel in tundish at exchanging of ladle
Inventor: IDE TSUTOMU
IPC: B22D11/10
Filed: 1983-12-20
Abstract: PURPOSE:To enable always supply of a molten steel contg. less inclusions by maintaining a constant level of the molten steel on the immersion nozzle side in the stage of exchanging a ladle by means of partition plates disposed freely movably in the longitudinal and height directions of a tundish. CONSTITUTION:A pair of partition plates 5 which are freely movable in the longitudinal and height directions of a tundish 3 are disposed in said tundish and continuous casting is accomplished by supplying a molten steel to the tundish from a ladle 1. While the plates 5 are held lowered in the bottom of the tundish 3 in the stage of starting the exchange of the ladle, the plates 5 are laterally moved to an immersion nozzle 4 side according to the decreased amt. of the molten steel in the tundish 3 and even after the completion of the ladle exchange, the lateral movement is continued until the molten steel head between the plates 5 restores the adequate level. The plates 5 are thereafter ascended and reset to the home position. The specified level of the molten steel in the mounting position of the tundish is thus maintained in the stage of exchanging the ladle, by which the supply of always the molten steel contg. less inclusions is made possible.

Title: Semiconductor laser device
Inventor: MURAKAMI TAKASHI
IPC: H01S5/00
Filed: 1983-12-19
Abstract: PURPOSE:To increase the yield by forming a current stricture layer of a two- layer structure of an n type layer and a p type layer and composing the p-n-p (or n-p-n) structure together with a substrate so as to preventing the current from flowing into the part where a defect is generated. CONSTITUTION:The first layer 2a consisting of n type GaAs and the second layer 2b consisting of p type GaAs are grown in order by liquid-phase growth on the whole surface of a substrate 1 consisting of p type GaAs as a current narrowing layer 2. After that, groove 3 is formed by chemical etching over the second layer 2b. Thus, the p-n-p three-layer structure can be obtained over the whole surface except the groove 3. The manufacturing processes after this are similar in the conventional art. Consequently, even if a defective growth point 10 is generated at crystal growth after a lower clad layer 4 and the lower clad layer 4 and an active layer 5 are cut partly to bring an n type upper clad layer 6 in contact with the current narrowing layer 2 in that part directly, that contact plane is the p type second layer 2b and the p-n-p three-layer structure is formed under that layer so that the current does not flow in that part.

Title: Drive unit for paper feeding tray
Inventor: YOSHINO HIROBUMI
IPC: G03G15/00
Filed: 1986-10-14
Abstract: PURPOSE:To make a condenser-run induction motor miniaturizable, by driving a phase advancing condenser in a way of selecting its capacity separately at starting time and stationary time. CONSTITUTION:Each value of phase advancing condensers 24 and 25 is set to C1+C2 only at the time of starting and started, and after the elapse of the specified time, the value is selected to the C1, driving these condensers. With this, not only large starting torque is securable but also a motor 26 is drivable without entailing any drop in torque and efficiency at the time of stationary drive. The motor 26 in a control system like this is used, thereby as a drive motor not required for constant speed rotation, a yet smaller motor is adoptable. And especially, in case of using it as a paper feeding tray for up-down driving, if it is started only at the time of starting, a load variation at the time of stationary driving afterward is relatively less, so that it is usable by lowering its revolving speed down to somewhere about the operating torque.
