Title: Semiconductor device
Inventor: KOYAMA KUNIAKI
IPC: H01L27/02
Filed: 1983-09-13
Abstract: PURPOSE:To enable to readily alter a protecting withstand voltage by forming two or more reverse conductive type wells at the prescribed interval on one conductive type semiconductor substrate, connecting the one well to the substrate to set to the same potential and forming a diode of the other well and the substrate. CONSTITUTION:When a voltage is applied to an input terminal A, a depletion layer expands from a boundary between a P type silicon substrate 1 and a well region, and when N type well regions 3a, 3b are formed at a suitable distance, the regions 3a, 3b are connected via the depletion layer at a voltage lower than a breakdown voltage between the substrate 1 and the N type wells to flow a current. Accordingly, a voltage at a B point is clamped by the potential divided by a resistor R, but the voltage at the B point can be set to a voltage lower than the breakdown voltage between the substrate and the N type wells from lateral N-P-N type bipolar transistor characteristics having negative resistance. Consequently, when the regions 3a, 3b are formed at a suitable distance, the protecting voltage can be altered freely to a low voltage without increasing the density of the N type wells.

Abstract: PURPOSE:To make a more wider range of adjustment of fire power by a method wherein a surface area of the wick and an amount of radiation of a radiator connected to a fire tray through a thermal conductor are simultaneously controlled. CONSTITUTION:When a wick 13 exposed to an ignition chamber 14 is set fire, the ignition is initiated with air flowing from aeration holes 12.

The calorie to be inputted to the wick 13 under a thermal conduction from the storing part 17 is guided to the heat exchanger 6 through the thermal conductor 7. The amount of radiation is controlled by a method wherein an adjusting plate 18 in a cooling chamber 1 is cooperated with a dial 19 to vary a degree of opening and closing. In turn, the wick 13 is cooperated with the dial to move up and down and thereby an area of exposure can be increased or decreased.

Abstract: PURPOSE:To use in common a supervisory device of a subscriber terminal device by using a transmission circuit for a call signal and an alarm signal as one system and transmitting selectively only a required signal at signal transmission in time division. CONSTITUTION:When a talking network 1 detects that a subscriber terminal 2 is in off-hook state for a prescribed time, the talking network 1 commands the transmission of alarm signal to a signal transmission control circuit 4.

When the subscriber terminal devices 2 recognizes it and hooks on, a supervisory circuit 33 detects it and informs it to the control circuit 4. The control circuit 4 stops the contact operation of the signal selection circuit 35 to switch the subscriber terminal device 2 to the talking network 1. The procedure above is executed similarly in case of the transmission of a call signal.
