Title: Conference telephone system
Inventor: NIIMURA NAGATO
IPC: H04M9/00
Filed: 1987-05-30
Abstract: PURPOSE:To simply prevent the generation of a ringing condition and to receive not with an earphone by equipping a microphone to have a sound field sensitivity characteristic almost symmetrical to a plain including a soundgathering diaphragm and a speaker whose central axis takes a position in this plain. CONSTITUTION:A microphone 70 to have a sound field sensitivity characteristic almost symmetrical to a plain to include a sound-gathering diaphragm and a speaker 50 provided so that a central axis can take a position in the plain are equipped. Thus, a receiving sound outputted from the speaker forms sound fields almost equal at both sides of the diaphragm of the microphone and since sound pressures on Loth, surfaces of the diaphragm are mutually canceled each other, a power sound-gathered in the microphone is extremely small and a line does not come to be a ringing condition. For a transmitter, by taking the position as near as possible to the front to the microphone, the sound field strength degree of the transmitted sound comes to be unbalanced on both sides of the diaphragm of the microphone and a remaining acoustic power mutually canceled on the diaphragm is sound-gathered, comes to be a power enough to a conversation and transmitted.

Title: Transformer protective-relay
Inventor: NIINUMA SHIGERU
IPC: H02H3/28
Filed: 1988-06-06
Abstract: PURPOSE:To certainly work a relay at the time of an internal accident and prevent error interruption from being generated at the time of a poor condition by using the relay working only at the time of the generation of the accident. CONSTITUTION:When the secondary side of a current transformer 4b is disconnected in a state that load current flows, then current i1 flows into a ratio differential relay 5, and the relay 5 is worked. In the meantime, in variation detecting element 8-1 on an increasing side, current I1 is not changed, and so the element 8-1 is not worked. Besides, in a variation detecting element 8-2 on the increasing side, current I2 is changed by  IX on a reducing side, and so the element 8-2 is not worked. Accordingly, an AND circuit is not materialized, and trip command T is not generated, and so unnecessary working is prevented from being generated. In case of an internal accident, current is increased, and so either variation detecting element 8-1 or 8-2 on the increasing side is worked. Accordingly, the output of the ratio differential relay 5 is worked, and either variation detecting element 8-1 or 8-2 on the increasing side is worked, and so the output T of the AND circuit 10 is generated, and tripping can be performed. Accordingly, on internal and external accidents, a normal reaction is performed, and even if the poor condition of disconnection or the like is generated, unnecessary interruption can be prevented from being generated.

Abstract: PURPOSE:To prevent the occurrence of flame failure of a high-pressure discharge lamp at the time of a start by setting the load characteristic of a lighting circuit to the full-lighting state for a start immediately after a power source is turned on if the dim-lighting mode is selected, and gradually changing the load characteristic to the dim-lighting state while maintaining the tube power nearly constant when the tube power nearly reaches the stable lighting state. CONSTITUTION:The Zener voltage of a Zener diode ZD1 is set so that the Zener diode ZD1 is excited to start the reduction of the current flowing in a bidirectional thyristor Q1 when the lighting state of a high-pressure discharge lamp DL, on the load characteristic in the full-lighting state nearly reaches the stationary lighting power in the dim-lighting state after the high-pressure discharge lamp DL is started before the high-pressure discharge lamp DL is changed to the stationary full-lighting state. When the Zener voltage of the Zener diode ZD1 is thus set, the starting process of the high-pressure discharge lamp DL is moved from the point FS to the point FL0 on a solid line BF as shown by an arrow (1), then it is gradually moved from the point FL0 to the point DM as shown by the arrow (2) by the action of a transistor Q2 while the tube power is kept constant, and the stable dim-lighting state is obtained.
