Title: Manufacture of lead storage battery
Inventor: SAITOU SHINJI
IPC: H01M50/463
Filed: 1984-02-28
Abstract: PURPOSE:To prevent internal strapping by calculating the protrusion amount of a separator from a plate based on the easiness to make current flow through the separator between positive and negative electrode plates and the easiness to make the current flow applied in an electrolyte through the separator. CONSTITUTION:A separator S is inserted between positive and negative electrode plates and the current path between the plates consists of a path I composed of P A N, path II composed of P (section protruded outside the plate)B N, and path III composed of P C N. The optimum value of the protrusion amount DB of the separator S from the peripheral section of the plates P and N is calculated by comparing the electric conductivity in the path III and the electric conductivity of the path I applied directly in an electrolyte through the separator S and is set as shown in the path II. As a result, life performance can be improved by establishing the matching of an assembled element based on the protrusion amount DB of the separator required for prevention of internal strapping at the minimum.

Title: Recording muse signal reader
Inventor: HAYASHI HIDEKI
IPC: G11B20/02
Filed: 1989-02-17
Abstract: PURPOSE:To prevent the generation of incorrect clamping due to drop-out by clamping a low frequency component in a reproduced MUSE signal at a pre scribed reference potential level only when a drop-out detecting signal does not exist and an HD period detecting signal exists. CONSTITUTION:When drop-out is not generated, a high level drop-out detecting signal (a) is not outputted from a drop-out detecting circuit 15 and a high level signal is supplied to one input terminal of an AND gate 12 connected through an inverter 13. Since a high level HD period detecting signal (b) is supplied to the other input terminal of the AND gate 12 in the HD period, the output of the AND gate 12 is turned to the high level in the HD period. Thereby, an analog switch 11 is turned on in the HD period and a reproduced MUSE signal supplied to the input terminal of a buffer amplifier 7 through a capacitor C is clamped to a reference potential E determined by the output voltage of a constant voltage source 8 through a resistor R. Thus, the generation of misclamping can be prevented.

Abstract: PURPOSE:To prevent an eaves from being formed on the sidewall of a contact hole by anisotropic etching by a method wherein a protective film is formed on the sidewall of the contact hole before the anisotropic etching for making an homic contact is performed. CONSTITUTION:Interlayer insulating films 3-7 are formed and thereafter, a contact hole 8 is formed by anisotropic etching.

Thereby, the infiltration of an etching liquid at the time of anisotropic etching into the films 3-7 is stopped by the film 11 and a probability that an eaves is formed on the sidewall of the hole 8 is eliminated.
