Title: Self-excited shunt device for ac exciter
Inventor: KORENAGA HITOSHI
IPC: H02P9/30
Filed: 1991-12-10
Abstract: PURPOSE:To reduce a capacity of an excited shunt device, to reduce in size the device and to improve stability by self-exciting to supply a predetermined field current to an AC exciter by a thyristor rectifier and a constant-excited controller. CONSTITUTION:When an output voltage of an AC exciter (AM) 1 is raised due to any cause, a voltage applied to a thyristor rectifier (ST) 15 is raised. Thus, the ST 15 is so controlled from a constant-excited controller 13 as to lower a DC voltage. As a result, a current to be supplied to a field winding 1b is lowered, an output voltage of the AM 1 is also lowered, and the output voltage is regulated. Thus, the output of the AM 1 is supplied to a main rectifier 11, a rectified DC current is supplied to a field winding 1b of a synchronous machine 12, and output from the machine 12 to a bus side. In this manner, since the constant exciting current is supplied to the winding 1b of the AM 1, a stable point can be obtained by holding at a predetermined position of a field resistance curve.

Title: Portable gas measuring device
Inventor: KUWABARA TAKASHI
IPC: G01N27/12
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To prevent the undesirable exhaustion of a battery. SOLUTION: A gas inlet 3 is bulged from a case 1. A small hole 1c is bored through in the periphery of the gas inlet 3, an movable piece 6b is protruded forward from the small hole 1c, and a switch main body is embedded. The switch is a power supply switch, and at the time when a sensor cap 5 is placed to a bulged part 1b at the time of non measurement, the movable piece 6b of the switch is pressed to open a contact and to turn the power off. At the time when the sensor cap 5 is removed for gas measurement, the pressure on the movable piece 6b is removed to close the contact and to turn the power on. Therefore, as electrical components are energized with current only at the time of measurement, the power supply switch is not left on to use a battery effectively.
