Inventor: MIURA OSAMU
IPC: H04M3/00
Filed: 1984-03-27
Abstract: PURPOSE:To make the contents of received traffic information accurate by transmitting the station information to a central unit if it is changed by an exchange device, and changing automatically the station information of the exchange device at the central unit according to the received station information. CONSTITUTION:The station information is sent to a central unit CT when a maintenance operator changes the station information through an extracting device DETi which is set opposite to an exchange device SWi.

Title: Audio conference device
Inventor: KIMURA JUNICHI
IPC: H04M1/00
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To always obtain a constant listening level even if the position of a voice input device is changed by installing an ultrasonic wave oscillating part in the vicinity of a voice output device, and installing an ultrasonic wave receiving part in the vicinity of the voice input device, and comparing a received signal with a reference signal. SOLUTION: An ultrasonic pulse generated by a carrier oscillator 7, a reference pulse oscillator 8 and a modulator 6 is emitted toward the inside of a conference room from the oscillating part installed in the vicinity of the voice output device (speaker) through a power amplifier 5. The ultrasonic wave receiving part 1 installed in the vicinity of the voice input device (microphone) receives the propagated and delayed ultrasonic pulse, and compares the pulse obtained through a microphone amplifier 2 and a demodulator 3 with a reference pulse in a comparator 9. Distance between the microphone and the speaker is calculated from that pulse time difference, and an audio conference control part 10 controls speaker sound volume in accordance with this distance.  Thus, even if a speaking person moves, and a listening position is changed, the constant listening level can be maintained automatically.

IPC: H02M9/04
Filed: 1990-03-09
Abstract: PURPOSE:To simplify circuit configuration by using a core of a saturable magnetic substance for a transformer, and boosting a pulse and contracting the pulse width simultaneously. CONSTITUTION:The primary winding of a transformer 5 is connected to a charging power source 1 through a capacitor 4, and the core of the transformer 5 is made of a saturable magnetic substance.

Inventor: KATAYAMA TAKASHI
IPC: H01J11/12
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To effectively use ultraviolet rays during discharge without raising an address discharge starting voltage by increasing thickness of a phosphor layer near the top of a rib to be not less than a specific ratio. SOLUTION: Thickness of a phosphor layer formed on the side surface of a barrier rib is set not less than a half of that of a phosphor layer on a groove bottom between barrier ribs. For example, the phosphor layer 28 is formed between the ribs 29, this layer thickness is the same as the layer thickness tb on the groove bottom between the barrier ribs 29 and the layer thickness tw on the side surface of the rib 29, and especially the layer thickness tt near the top of the rib 29 is set the same as the side layer thickness tw. The layer thickness tb of the layer thicknesses of the phosphor layer 28 affects an address discharge starting voltage, and the layer thicknesses tw, tt hardly affect it. Therefore, the layer thickness tb is adequately set for setting the address discharge starting voltage to be an adequate value.  Because high address discharge starting voltage is required following increase of the layer thickness tb the layer thickness tb is set so that this voltage matches to a driving circuit ability of PDP, and the layer thicknesses tw, tt are set to be the same degree as the layer thickness tb.
