Title: Pla and pla module generator forming the pla
Inventor: KURIMOTO MASAHIRO
IPC: G06F17/50
Filed: 1994-10-11
Abstract: PURPOSE: To reduce the area of a PLA and also to reduce the total area of an LSI. CONSTITUTION: In the PLA, the input lines I1, I1/, I2, I2/, I3 and I3/, the output lines O1 and O2, and the product term lines P1 to P4 are arranged crossing each other on a P type substrate. The NMOS T1, T2... are added among those input, output and product term lines based on the given truth table so that the logical output of the truth value table is acquired. In such a constitution, an AND array 1 and an OR array are constructed. The substrate potential fixing subcontacts A13, A32, O12, O21, O41 and O42 are provided in the frames where the NMOS T1, T2... are not arranged among those frames that are formed by the input, output and product term lines of both AND and OR arrays. Thus, these subcontacts stabilize the substrate potential and secure a sure operation of the PLA.

Title: Mounting structure of external wall panel of gable wall in gambrel roof
Inventor: NISHINOMIYA TAKU
IPC: E04B7/00
Filed: 1994-10-11
Abstract: PURPOSE: To simplify the installation by screwing external-wall receiving frames at both ends of a lower chord material forming triangular gable walls by combining a plurality of panels and mounting the lastly mounted external-wall panels of triangles on both sides from the outside. CONSTITUTION: External-wall receiving frames 22 prepared by bending channel steel in an L shape are screwed at both ends of the lower chord material 18 of a framework frame. The trinagular gable walls of gambrel roofs are composed along the lower chord materials 18. Central-section framework frames 11 and intermediate-section framework frames 12 are set up successively while triangular framework frames 13 at both ends are installed lastly. When the last framework frames 13 are fitted, the framework frames 13 are attached onto the external-wall receiving frames 22 by screws, etc., from the outside, and mounting difficult to be worked from the rear sides is unnecessitated. Since the framework frames 13 are not conspicuous from the outside, appearance is not deteriorated even when the heads of the screws are exposed. Accordingly, the mounting operation can be conducted efficiently.

Title: Catalyst for preparing ammonia
Inventor: AKISHIKA KENICHI
IPC: B01J23/58
Filed: 1989-09-21
Abstract: PURPOSE:To obtain a highly active catalyst by removing the poisoning of the catalyst due to chlorine by impregnating a hardly reducible oxide carrier with a ruthenium metal component using a ruthenium compound containing no chlorine. CONSTITUTION:A ruthenium compound containing no chlorine such as a ruthenium carbonyl complex or ruthenium nitrate is supported by hardly reducible oxide such as alumina or magnesia and reduced under vacuum and/or a hydrogen gas stream to obtain a metalloid ruthenium catalyst.

Abstract: PURPOSE:To decrease the refractive index difference between the optical waveguide and a clad by setting the grating constant of the optical waveguide smaller than the grating constant of a clad layer or attaining the grating matching an optical waveguide layer and the clad layer with InP and forming the waveguide layer or clad layer of quaternary mixed crystal of AlGaAs or AlGaAsSb. CONSTITUTION:When the grating constant of a semiconductor layer is small and tensile stress is applied from a peripheral semiconductor layer, the refractive index increases and when the grating constant is large and the layer is compressed, the refractive index decreases. For the purpose, the grating constant of the optical waveguide 6 is set a little bit smaller than those of clads 4 and 8 and then a waveguide which has a small refractive index difference is obtained. Further, while the grating matching of the optical waveguide 16 and clads 14 and 18 with the InP is performed, at least either of the optical waveguide and clads are formed of quaternary mixed crystal of AlGaInAs or AlGaAsSb. While the grating matching with the InP is performed by adjusting the quaternary composition ratio, the refractive index of the clads can be adjusted to a little bit less than the refractive index of the waveguide and the adjustment can be made much easier than a conventional quaternary system of InGaAsP and the waveguide which is suitable for, specially, a 1mum-band optical communication is obtained.
