Title: Manufacture of tantalum anode member
Inventor: TSUTSUI MAKOTO
IPC: H01G9/00
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a tantalum anode member of a structure, wherein a tantalum wire is secured to the high-density sintered region of a tantalum sintered body, which is provided with a low-density sintered ragion and the high-density sintered region buried in this low-density sintered region, by welding, which can manufacture the tantalum anode member, which generates little leakage current at the time when the anode member is formed into a capacitor compared with a conventional method, wherein a sintering is executed two times, of manufacturing the tantalum anode member. SOLUTION: In a process (a step S2A) of forming a low-density molded material, the formed low-density molded material is kept holded intact in a die, which is used as a molded cavity. In the following process (a step 6A) of welding a tantalum wire, the tantalum wire is welded to the high-density sintered region of a tantalum sintered body in a state remaining as the molded material is held in the die. A sintering for reinforcing the mechanical strength of the molded material, which is necessary in a conventional method of manufacturing a tantalum anode member, becomes unnecessary and as the sintering to be executed is reduced to only one time (a step S7), an oxygen diffusion into the anode member is decreased and the content of oxygen in the anode member is decreased. As a result, a leakage current due to the oxygen, which is contained in the anode member, is decreased.  The productivity of the anode member is also increased.

IPC: H04N5/262
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To obtain the special effect digital device in which a memory capacity to store read addresses in response to the special effect is reduced. SOLUTION: A CPU 32 calculates a read address in response to the special effect designated by a parameter input section 31 and compresses it and stores the result to an address data memory 33. In parallel with processing of writing image data 11 to an image memory 13, the compressed read address is read from the address data memory 33 and expanded sequentially by an expander 36. Image data are read in real time from the image memory 13 by the expanded read address. Since the read address obtained in advance is compressed and stored, the capacity of the memory storing the read address is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a deodorant containing a metal complex catalyst capable of deodorizing acetaldehyde gases contained in the smoke or the like of a cigarette and displaying a stable deodorizing performance for various odor components, and a deodorizing filter using the deodorant. SOLUTION: In the case of a deodorizing material obtained by mixing metal phthalocyanine and water soluble cyclodextrin with each other, the water soluble cyclodextrin first adsorbs an odor molecule and then the metal phthalocyanine decomposes and adsorbs the odor molecule. In this case, as a deodorizing mechanism for an odorous molecule, the odorous molecule must be first arrested and the metal phthalocyanine in the vicinity thereof must decompose the odorous molecule. Cyclodextrin (the example shows the molecular structure of β- cyclodextrin) has several glucose molecules annularly bonded and has a hollow cylindrical structure. In addition, the cavity internal space of the annular structure is hydropholic and the odorous molecule is confined therein.
