Title: Discharge flow controller for immersion nozzle for continuous casting
Inventor: KATO MASANORI
IPC: B22D11/115
Filed: 1986-11-06
Abstract: PURPOSE:To decrease the defects occurring in the inclusions and bubbles generated in a slab by providing an electromagnetic brake to the lower part of the long side wall surface of a mold for continuous casting and decelerating the discharge flow from a nozzle. CONSTITUTION:The discharge flow V1 from the immersion nozzle 3 in the continuous casting mold is decelerated by the electromagnetic brake 4 provided in the lower surface of the long side wall 2 surface to prevent the capturing of the inclusions, bubbles, etc., under the skin or in an ingot at the time of continuous casting. Horizontal flow V3 is further generated in a molten steel by an electromagnetic stirrer 5 in the region near the meniscus of the molten steel supplied into the casting mold. Cleaning of the front surface of the solidified shell and the joining of the bubbles are positively executed to accelerate the floating of the inclusions and bubbles without assisting the slag patches generated by the intrusion of a mold flux into the molten steel by the fluctuation in the meniscus 6 of the molten steel.

Title: Electrophotographic device
Inventor: HOSOYA MASAHIRO
IPC: G03G15/10
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To minimize the adhesion of solvent to a latent image holding body and a paper and to prevent the solvent from being discharged outside a machine by providing the surface of a developing means with many conducive projection parts, forming a concentrated electric field between the latent image holding body and the conductive projection parts and developing an electrostatic latent image by making the droplets of liquid developer fly toward the latent image holding body from the conductive projection parts by the concentrated electric field. SOLUTION: A developer carrier 25 is provided with many needle-like or fiber-like projection parts 27 formed at the outside circumference of a conductive roller substrate 26. The developer is held by the projection parts 27 and carried to a position opposed to the latent image holding body 24 by the rotation of the carrier 25. When an electrode approaches this area, the solid part of the developer is aggregated at the tip part of the needle-like electrode by the concentration of the developer because the electric field is intensively concentrated at the tip part of the needle-like electrode. This aggregate is torn off and made into the droplets so as to fly. While the droplets are adhered to a latent image, the latent image is developed.  In order to make the droplets sufficiently fly, the electric field being at least 500 V/mm is required to be formed between the needle-like electrode and the holding body 24.

Its reflected wave from the mirror 7 is transmitted through the element 6 and glass body 1 again and then guided to a projection optical fiber 5 through the 2nd uniaxial plane crystal 3. In this case, the reflected light beam whose incidence light beam is closest to the glass body 1 on the interface of the uniaxial lane crystals 2 and 3 is selected among four projection light beams l11-l22 projected by the lane crystal 3 and admitted into a projection optical fiber 5.

Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To prevent falling of a bump by placing resin or a film covering a specified ratio of the volume of bump between the bumps on a solder bump plane. SOLUTION: Resin 5 is placed between bumps on a bump plane corresponding to the rear surface of a printed wiring board 2 to cover 50% or more of the volume of a bump 4, i.e., to cover the bump 4 while straddling the maximum diameter thereof. Forward end of the bump 4 projecting from the resin or film 5 is flattened by pressing or polishing along the resin or film 5. Since the resin or film 5 can support the bump 4 from below, the bump 4 can be prevented from falling resulting in uniform height of the solder electrode plane of a BGA-(ball grid array) package.

Title: Cooling module
Inventor: OKAMOTO SHIGEKI
IPC: H01L23/473
Filed: 1989-10-11
Abstract: PURPOSE:To improve productivity based on enhanced cooling efficiency and reduced manpower by forming at least the section of a plate, to be welded to a bellows, of nickel and the other sections of said plate of copper. CONSTITUTION:A nickel layer 20a is formed on a part of a plate 20 to be welded to the end face 3b of a bellows 3. Since nickel has lower heat conductivity than the prior art beryllium copper, welding can be carried out with sufficient depth. The central part of the plate 20 which adheres to the surface of LSI comprises a pure copper section 20b. The heat conductivity of copper is increased by about four times compared with that of the prior art beryllium copper and the heat from the surface of LSI is extremely efficiently transmitted to pure water circulating through the plate, which improves the cooling efficiency of LSI sharply.
