Title: Vacuum deposition device
Inventor: SHIMOZATO YOSHIO
IPC: C23C14/24
Filed: 1981-12-04
Abstract: PURPOSE:To make the responsiveness of the rate of evaporation fast and to prevent splashing by installing a heater which is a heating soruce in the upper part in a vacuum deposition furnace and floating a carbon block in the bath. CONSTITUTION:When a shutter 4 is opened in the stage of vapor deposition, zinc vapor is plated through an opening 6 on a steel strip 10 which travels in, for example, a right direction above the body 1 of the vapor deposition furnace. Here, molten zinc 7 is heated directly by the heater 8 in the upper part of the inside of the furnace or is heated with a carbon block 11 floating in the zinc 7 and evaporates successively from the surface layer. Thus, the evaporation responds quickly to the change in the rate of heating from the heater 8 and since the time for settling decreases, the generation of off-specification products decreases. The formation of the oxide film on the liquid surface of the zinc is suppressed by the reducing force of the block 11, splashing is made difficult to arise and the sticking of liquid drops upon the products is prevented.

IPC: C21C7/10
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To prevent the breakage of a core metal and a cooling mechanism in the inner part even in the case of invading molten steel through joint and crack of a refractory by constituting the lower end part of the core metal corresponding to invading range of the molten steel with a solid metallic plate without the cooling structure. SOLUTION: In the core metal structure of an immersion tube, the upper part in the core metal 1 from the position almost corresponding to the height of the molten steel surface 10 at the outside of the immersion tube is made to the part having the cooling structure. The solid metallic plate 5 as the other one with the core metal 1 is connected with the lower side from the molten steel surface 10. The thickness of the metallic plate 5 is unnecessary to be the same thickness as the cooling structural part and desirable to be thinner in such range that the refractory at the lower part can structurally be supported. The connecting means is desirable to weld under consideration of the sealness of a vacuum treatment.  Since this core metal structure has the cooling structure in a large part, this core metal can prevent to heat at >=1000 deg.C and the thermal deformation of the core metal 1 is prevented and the structural stability of the refractories 2a, 2b can be secured.

Title: Delaying circuit
Inventor: WATANABE YUKO
IPC: H03K5/133
Filed: 1987-08-05
Abstract: PURPOSE:To secure a large delay time by decreasing a response speed of an inverter circuit, by constituting the titled circuit so that the potential related to a source electrode of the inverter circuit drops due to a voltage drop of a first MOSFET. CONSTITUTION:As for a P type MOSFET 11, the gate electrode and the drain electrode are connected to each other, therefore, a potential difference between the source electrode and the drain electrode, and a potential difference between the gate electrode and the secure electrode become equal, and the potential in the drain electrode becomes the potential being lower than by a threshold portion than the power source potential +VDD of the positive electrode connected by the source electrode. Also, when the potential of the source electrode is low, a response speed of the P type MOSFET becomes low. Accordingly, a response speed of a P type MOSFET 12 becomes lower surely than the case when the P type MOSFET 11 does not exist and the source electrode is connected directly to the power source potential of the positive electrode. In such a way, a large delay time can be secured.
