Title: Shaped fiber body and production thereof
Inventor: JIYON AARU MOTSUTO
IPC: B22D11/10
Filed: 1990-04-27
Abstract: A ladle is used in the manufacture of metals and for receiving molten metal for further chemical processing or for transportation. The ladle comprises a glass-cement outer shell (18), refractory linings (20,22) and trunnions (30). The ladle is transparent to a wide range of electromagnetic radiation wavelengths which allows the metal to be heated or stirred by induction without heating the ladle itself. As the ladle is made of glass fibre and an inorganic cement, strength is provided along with high temperature resistance. The ladle is manufactured by winding glass fibre around a mandrel, and incorporating an inorganic cement. The cement may be coated on the fibre as an aqueous slurry, and the product allowed to air cure after winding. Alternatively, the cement may be adhered to the fibre by electrostatic attraction. After winding is complete, additional cement may be added and the product placed in an autoclave supplied with steam whereby the cement takes up water; it is then allowed to cure. After curing, the moulding is preferably sawn in half to form two inductively transparent ladles.

Title: Exposure controller for electronic camera using solid-state image pickup device
Inventor: TANAKA YOSHITO
IPC: G03B7/16
Filed: 1988-05-06
Abstract: PURPOSE:To always obtain proper exposure by measuring the brightness of an object in advance, calculating a prescribed exposure time due to natural light of a solid-state image pickup element based on the result of photometry, exposing a prescribed time by natural light and applying flash light for image pickup, and stopping the exposure so as to obtain optimum exposure for the main object. CONSTITUTION:The brightness of an object is measured in advance and a prescribed exposure time by natural light is calculated based on the photometry information. As soon as the electron charge of the solid-state image pickup element is started, the photometry is started and a flash device is lighted after a prescribed exposure time elapses and the storage of charge of the solid-state image pickup element is stopped when the object has a proper exposure. Thus, the dimmer of the flash light is applied easily by the same photometric means in the same integration time as the direct photometry by the natural light and the exposure is controlled accurately by the flash light and the tracing for proper exposure with respect to brightness change of the object is facilitated.

Title: Mold attachment
Inventor: TOTSUKA YOSHIO
IPC: B29C33/04
Filed: 1993-04-15
Abstract: PURPOSE:To enhance forming efficiency and product yield and realize low cost by a method wherein piping for supplying heating and cooling medium is arranged under the condition that the space is left between the rear surface of a mold and the piping and, in addition, nozzle holes, through which heating and cooling medium is radiated against the back of the mold, are formed on the piping. CONSTITUTION:After molding material W is charged in a product molding part 4, which is between both the upper mold 2 and the lower mold 3 of a molding device 1, heating medium is supplied from medium supplying source to respective pipings arranged on the rear surface 3a side of the lower mold. The heating medium supplied in the pipings 10 is radiated as mist from respective nozzle holes 11 against the rear surface 3a of the lower mold. Since the pipings 10 do not contact the lower mold 3, the heat exchange between the heating medium in the pipings 10 and the outside is small and the temperature change of the heating medium in the pipings 10 is small. Accordingly, the heating medium having nearly uniform temperature is radiated so as to allow to heat uniformly the whole lower mold 3. The heating medium, the heat of which is dissipated to the rear surface 3a of the lower mold, changes heat directly to the lower mold 3, resulting in thermally hardening the molding material.
