Title: Squeegee and its manufacture
Inventor: TAGAMI YOSHIAKI
IPC: B41F15/44
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To easily change an attack angle by providing a bottom part, a side part, and a tapered part which covers from a bottom part of a squeegee section to the side part in the squeegee section. SOLUTION: In a squeegee section, a tapered part 11t is formed by polishing from a bottom part 11b to a side part 11s. In a squeegee having the tapered part 11t attached to a printing face at an angle α, the angle of the tapered part becomes equal to also angles b1 and b2. An attack angle (c) of the squeegee section and the printing face becomes angle (a)-angle b1 (angle b2). Also, the angle of the bottom part 11b of the squeegee and the tapered part 11t becomes 90 deg. + angle b1 (angle b2). For example, when the angle α of the squeegee is 70 deg. and the angle b1 (angle b2) of the tapered part 11t is 10 deg., the attack angle of the squeegee and the printing face becomes 70 deg.-10 deg.=60 deg..  Thus, the taper angle is changed without changing the angle α of the squeegee which is attached to a screen printing machine, so that the attack angle (c) can be easily changed.

Filed: 1991-01-29
Abstract: PURPOSE:To simultaneously remove organic contaminant and fine particlelike contaminant of a compound semiconductor single crystalline wafer by organically cleaning the wafer by using mixture solution of trichloroethylene and acetone as an organic solvent. CONSTITUTION:As an organic solvent, mixture solution of trichloroethylene and acetone, is used. The mixture in which the trichloroethylene and the acetone are mixed at various ratio, is dropped on a surface of a GaAs mirror-surface wafer 1, and a contact angle theta of the droplet 2 is measured. Then, the more the mixture ratio of the acetone is increased, the less the theta is decreased, the wettability of the GaAs surface with the mixture is improved, and it reaches substantially a constant value at 40 vol.%. Accordingly, since the mixture in which the trichloroethylene and the acetone are mixed in a range of 8: 2 to 6:4 of a volumetric ratio has solubility of wax and excellent wettability on the surface of the wafer, it is expected as a cleanser having performance of simultaneously efficiently cleaning and removing organic contaminant and fine particlelike contaminant.

Title: Fault detecting method for multiprocessor system
Inventor: MUKAI ATSUSHI
IPC: G06F15/16
Filed: 1990-02-05
Abstract: PURPOSE:To speedily notify the generation of abnormality to another processor by making interruption on the other processor by a timer only when generating the abnormality in a processor, and activating a fault processing in each processor corresponding to this interruption. CONSTITUTION:When each processor P1 (P2) executes self diagnosis, a shared timer CWDT is reset when the processor is normal. Therefore, the other processor P2 (P1) can be concentrated in the self-processing without loading the interruption. When the fault is generated or when the processor is turned to a stop state, the shared timer CWDT is not reset, and therefore, the interruption is made on the other processor P2(P1) by operating the shared timer CWDT. Then, a fault processing is executed. Thus, the generation of the fault is speedily detected by a simple software.

Title: Manufacture of electrolyte retaining matrix for fuel cell
Inventor: TAKAHASHI KENZO
IPC: H01M8/02
Filed: 1988-02-08
Abstract: PURPOSE:To increase phosphoric acid permeability and retainability to increase cell performance and lengthy stability by kneading an electrolyte retaining material comprising boron carbide and silicon carbide, a binder, and a plasticizer, and forming, then removing the plasticizer by solvent extract. CONSTITUTION:An electrolyte retaining material comprising boron carbide and silicon carbide, a binder, and a plasticizer are kneaded and formed, then the plasticizer is removed by solvent extract. Since a baking process is not applied, the binder fibrils formed in the kneading process entangle in the electrolyte retaining materials to fix them. This increases phosphoric acid permeability and retainability because the surface of the electrolyte retaining material is not covered with the melted binder different from a conventional process. Phosphoric acid permeability and retainability are increased to increase cell performance and lengthy stability.

Title: Production of thin metallic film
Inventor: HONDA KAZUYOSHI
IPC: G11B5/85
Filed: 1985-02-14
Abstract: PURPOSE:To prevent the generation of wrinkles and to form stably a thin metallic film on a long-sized high-polymer substrate by separating the long-sized high-polymer substrate traveling on a can to multiple lengths and forming the thin metallic film over the entire width of a part of such lengths. CONSTITUTION:The long-sized high-polymer substrate 7 travels along the can 8. The substrate 7 contacts tightly with the can 8 at the same instant when the thin metallic film begins to be formed on the substrate 7 by the impression of the voltage to a bias roller 11. The thermal damage of the substrate 7 is thus prevented. Shearing blades 12 are provided in the mid-way from an unwinding system 6 toward the can 8 to cut the substrate 7 plural lengths such as three lengths; one length for the main part for vapor deposition and two lengths for the part including margins. The generation of the wrinkles is eliminated from the difference in thermal load between the main part for vapor deposition and the margin parts. The film deposited by evaporation is thus formed on the main part for vapor deposition without the wrinkles.
