Title: Photolithographic device
Inventor: SAKUMA SHIGERU
IPC: H01L21/027
Filed: 1996-08-20
Abstract: PROBLEM TO BE SOLVED: To enhance the exposure throughput of a device by using a calcium fluoride crystal having a prescribed purity value as an optical material, in a photolithographic device using an ArF excimer laser as its light source. SOLUTION: In this device, the calcium fluoride crystal used is required to contain a <=1×10<18> atoms/cm<3> of the total amount of alkaline earth metals as impurities. When this crystal is irradiated with an ArF laser, color centers due to impurities in the crystal are generated. Although an absorption band(s) due to the color centers appears in the wavelength region(s) other than 193nm, since the absorption band(s) is not sharp or steep, the color centers also affect the transmissivity at 193nm of the crystal. Since the concn. of color centers correlates with the concn. of impurities represented by alkaline earth metals and the energy density of the ArF laser used, selection of fluorite having appropriate impurity concn. according to the design and in particular use of fluorite contg. a restricted amount of Sr are important.  Thus, the reduction in transmissivity of the fluorite crystal is decreased and the exposure throughput of the device is enhanced to a level ten times as high as the conventionally attainable throughput.

Title: Maximum likelihood decoder
Inventor: MIYAMOTO YOSHINORI
IPC: H04L25/08
Filed: 1988-09-02
Abstract: PURPOSE:To attain a low bit error rate by detecting an impulse noise having a long amplitude by suppressing its pass likelihood at the time of receiving this impulse noise. CONSTITUTION:A likelihood correcting part 13-1 is placed between a maximum value selecting part 21-1 and a pass memory selecting part 22, and a maximum value Pj of outputs P1 to PM of results of a pass likelihood calculating part 20-1 of a state 1 is inputted to an impulse noise detecting part 11-1, which discriminates whether this maximum value has an extent due to the impulse noise or not, and a discrimination result C and the value Pj are inputted to a likelihood suppressing part 12-1 to obtain an output Pj<1>. The impulse noise detecting part 11-1 compares the output Pj with a preliminarily given threshold value theta to output the discrimination result C. The likelihood suppressing part 12-1 suppresses the likelihood in the case of C=1 but outputs the output Pj as it is in case of C=0. Thus, the bit error rate is reduced.

IPC: G03C3/00
Filed: 1983-11-22
Abstract: PURPOSE:To ensure perfect light interception and sealing strength by further laminating a linear low-density PE type resin layer as a heat sealing layer on cross-laminated layers. CONSTITUTION:Unixially stretched films 1, 2 are laminated so that the stretched direction of each film crosses that of the other film at an angle of 45-90 deg. to form across-laminated film layers. One side of these laminates is coated with an L-LDPE type resin as a heat-sealing layer 4 to raise the heat-sealing strength high enough to package a heavy article. The L-LDPE is a copolymer of ethylene and one of alpha-olefins, and the L-LDPE type resin consists of >=60wt% L- LDPE as a main component, and other polyolefin type resins blended with it. The heat-sealing effect is not lowered by incorporating carbon in it to ensure light interception, and on the contrary, the addition of 1-15wt% carbon black enhances a heat-sealing effect.
