Title: Structure of installing section of insulated tank
Inventor: KATOU KOUJI
IPC: F17C13/08
Filed: 1981-10-12
Abstract: PURPOSE:To improve the aseismatic strength and the heat insulation performance, by fixing one end of a metallic installing member of an insulated tank to  the insulating member side of the side wall interior or the bottom wall interior while fixing the other end to a shape steel base or a concrete foundation. CONSTITUTION:One end of an installing metal 12 having the sufficient strength is fixed to the side wall interior 8 and the bottom wall interior 9 while the other end is fixed together with the flange section 7 of the exterior 3 to a base 15 through an installing bolt 14. Consequently when the seismic force is applied on a tank, the large inertia produced in a stored liquid is applied on the interiors 8, 9 but said inertia is not transmitted to the insulating material layer 4 but directly transmitted to the base 15 through an installing metal 12 and an installing bolt 14 fixed to the interior. Consequently the aseismatic strength can be improved by reinforcing the interiors 8, 9, installing metal 12 and the installing bolt 14 irrespective of the strength of the exterior 3 and the insulating material layer 4.

Title: Noise elimination circuit
Inventor: INOUE YUICHI
IPC: H03M1/12
Filed: 1991-07-03
Abstract: PURPOSE:To eliminate impulse noise or an abrupt signal fluctuation component superimposed on an analog input signal by allowing a sample-and-hold circuit not to fetch an analog signal but to hold a preceding value when no coincidence signal is outputted from a coincidence circuit. CONSTITUTION:When only an input signal D1 of a coincidence circuit 3-1 is changed while an analog input signal e1 is almost unchanged, outputs D2-D6 of an A/D converter 2 are not entirely changed and then outputs OUT2-0UT6 of circuits 3-2 to 3-6 are all at an H level. When the output OUT, of the circuit 3-1 goes to an H leel, an AND gate 4 is turned on, and a sampling pulse PS with respect to a sample-and-hold circuit 5 is outputted. The pulse PS controls the circuit 5, which fetches a signal e1 only when the pulse PS is applied and holds the preceding value when the pulse PS is at an L level. As a result, impulse noise superimposed onto the analog input signal is eliminated.

Title: Antistatic method at electron beam exposure
Inventor: NAKAGAWA TAKAYUKI
IPC: H01L21/027
Filed: 1978-12-26
Abstract: PURPOSE:To prevent the surface of an insulating layer on a semiconductor substrate from being electrically charged when it is subjected to electron beam exposure for forming a patten thereon, by providing beforhand a grounded reticulate conductive pattern on the mentioned surface. CONSTITUTION:An insulating layer 2 consisting of PSG to be used for multilayer interconnection or SiO2 is fixed on a Si substrate on which a LSI element is formed by a wafer process. A reticulate conductive pattern 3 of Au, Al or Cr is formed on the layer 2 by sputtering such that the pattern 3 corresponds to a chip isolation layer provided on a substrate 1. A resist film 4 is then coated on the whole surface of the substrate 1, and the resulting substrate 1 is set in a substrate support 8, which has a substrate urging plate 7, of an electron beam exposure device such that the substrate 1 is held in the support 8 via a substrate fixing portion 5 thereof and springs 6. Thus, the film 4 is destoryed by the fixing portion 5 to allow the pattern 3 to come into contact with the grounded support 8. When electron beam exposure is conducted in the above manner, electric charge occurring in the vicinity of the layer 2 escapes to the ground so that the electron beam is never deflected in the vicinity of the substrate 1.

When the output voltage V 2  of the circuit A 2  becomes lower than the reference voltage VRE, the voltage corresponding to the lowered voltage is delivered from the circuit 7. Thus the bleeder current Id flow to the feedback side circuit. As a result, the current Id flows when the output circuit current I 1  of the circuit A 1  becomes lower than the minimum current ILO to set the current I 1  to the current I 1  to the current ILO or higher. Accordingly, the output voltage of the circuit A 2  can be set to the regular level or higher even though the load of the circuit A 1  becomes zero.
