Title: Short-circuit recovery device for catv power supply and power supply system using the device
Inventor: MONMA MINORU
IPC: H04N21/647
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To automate power-on operation and eliminate need for fuse replacement by controlling a breaking circuit if current running through an apparatus for CATV exceeds a prescribed value for stopping power supply and, after the power supply is stopped, controlling the breaking circuit after every lapse of prescribed time, and attempting supply power. SOLUTION: A comparator 9 detects a change in DC voltage outputted from the first AC/DC converter 7 with reference to the DC voltage outputted from the second AC/DC converter 8. When it exceeds the reference value, a breaking circuit 1 is opened to stop power output to a feeder line. After a lapse of prescribed time, an integrated timer is actuated to close the breaking circuit 1 again for power output to a feeder line. The breaking circuit 1 is closed repeatedly while the DC voltage of the first AC/DC converter 7 is in excess of the reference value. Even if a short circuit occurs in a feeder line, a fuse is not blown, and automatic power-on operation is attempted, thus it is possible for a worker to eliminate need for manual power-on operation.

Title: Manufacture of semiconductor device
Inventor: YAMAGUCHI HITOSHI
IPC: H01L27/04
Filed: 1990-02-05
Abstract: PURPOSE:To eliminate the use of a circuit for temperature compensation and hence miniaturize an IC by adjusting the sizes of silicon crystalline grains constituting a polycrystalline silicon layer such that the coefficient of a change in resistance of an electric resistor element caused by a temperature change is zero. CONSTITUTION:A silicon layer is formed on a wafer 12 in a predetermined region (CVD process). Upon the formation of the silicon layer on a silicon oxide (SiO2) layer on the wafer 12 by the CVD process, since there is different a crystal structure between SiO2 and silicon formed on the former, the silicon layer becomes polycrystallized. The sizes of crystal grains of a polysilicon layer 30 becomes larger as temperature is raised. Accordingly, as CVD processing temperature is raised, the silicon layer can be increased while as it is lowered, the crystal grains can be reduced.
