Title: Production of core and electrodeposition bellows using this core
Inventor: MATSUKAWA NORITOMO
IPC: B22C9/10
Filed: 1988-11-30
Abstract: PURPOSE:To obtain the core which is transferred with the surface state of a casting as it is by heating a low melting alloy material to the temp. lower than its m. p. temp. and compressing and forging the material with the compressive strength much smaller than the compressive strength at ordinary temp. to obtain a master pattern core, and heating this core to the m. p. or above in a casting mold, then cooling the core. CONSTITUTION:The low melting alloy material 1 is heated to the temp. lower by about 5 to 70 deg.C than its m. p. temp. and is compressed and forged in this state to form the 3rd master pattern core 4. This master pattern core 4 is disposed into a casting cavity 22 of the casting mold 21 for the core of a segmental die type made into a bellows shape. The master pattern core 4 disposed in such mold is heated to the m. p. temp. of the low melting alloy or above to melt at least the surface of the master pattern core 4. The casting mold 21 for the core is then cooled down to the m. p. temp. of the low melting alloy or below and the molding is parted from the casting mold 21, by which the bellows core 5 is obtd. The bellows core is subjected to chemical plating or electroplating to form a thin metallic film 8 and the core is heated to the temp. above the m. p. of the low melting alloy and below the m. p. of the thin metallic film 8 to dissolve away only the bellows core 5. The metallic bellows having high quality is easily produced in this way.

Title: Image encoding device and decoding device

IPC: H04L9/08
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To accomplish both a high processing speed and secrecy with a simple configuration by fixing data of a specific bit in a template that extracts pixel arrangement information around an attentional pixel. SOLUTION: A template 1 fixes a specific bit, generates pixel arrangement information of input pixel data, outputs it to an entropy encoding means 2 and generates code data with the pixel arrangement information and directly inputted image data to be encoded. In the case of decoding, a decoded pixel is inputted to the template, the pixel arrangement information around an attentional pixel is extracted and an entropy decoding means performs decoding with the information and encoded data. In such cases, because about input decoded data, any pixel in the template is encoded as a fixed value, the template needs to make the pixel of a position that is the same with what is designated at the time of encoding a fixed pixel. Then, it is possible for a standard decoder to decode. Also, a circuit configuration becomes simple and it does not affect a processing speed.
