Title: Sound resonance arc stabilization device and method of discharge lamp
Inventor: JIEEMUZU TOOMASU DEEKIN
IPC: H05B41/28
Filed: 1994-03-10
Abstract: PURPOSE: To stabilize discharge and keep it close to an arc tube, and to prevent the discharge from swaying and dying out if operation is conducted at a high power level, by modulating an RF signal by a frequency in an acoustic resonance band lower than RF frequencies used for exciting discharge in the arc tube. CONSTITUTION: An electrodeless high intensity discharge(HID) lamp 10 comprizes an arc tube 14 and an excitation coil 16 surrounding that. A gaseous filler composed of sodium iodide, cerium iodide, and xenon is put in the arc tube 14. An RF power generator 18 is coupled to the coil 16 via a matching network 36 and a discharge arc 20 is excited by an RF signal. An RF frequency from the power generator 18 is amplitude-modulated by a frequency close to an acoustic resonance frequency according to a signal from an acoustic modulation signal generator 80. Preferably, an amplitude of this modulation is larger than an amplitude of the RF frequency by 5% or more. Further, it is preferable that the RF frequency is between 3 MHz and 300 MHz and that the modulating frequency is 3 MHz or under.

Abstract: PURPOSE:To simplify the titled apparatus by making it possible to measure a deuterium nucleus by the external lock thereof, by turning the gate circuit of the receiver of an observation system OFF when the observation system is irradiated with a high frequency wave and a lock system is irradiated with a high frequency wave. CONSTITUTION:In a lock system, the high frequency wave of the resonance frequency of a lock nucleus is subjected to pulse modulation by an irradiation gate circuit 10 and applied to a detection coil 3 or an external lock detecting coil 5 through a power amplifier 11 to excite resonance. This resonance signal is imparted to a phase detecting circuit 14 through a coil 15 and a receiver gate circuit 12 and converted to a dispersed wave form to be subjected to negative feedback to a magnetic field feedback coil 6. On the other hand, in an observation system, the high frequency wave of the resonance frequency of an observation nucleus is subjected to pulse modulation by an irradiation gate circuit 19 and applied to a power amplifier 20 and the coil 3 to excite the resonance of a specimen 2 to be observed. This resonance signal is taken in a data treating apparatus 25 as a free induction attenuated signal through the coil 3, a receiver gate circuit 21 and a phase detecting circuit 23. Therefore, the high frequency irradiation pulses of the observation system and the lock system are locked in a time sharing manner by the gate 21.

Title: Piezoelectric bimorph oscillator
Inventor: KOTANINO AKIO
IPC: H01L41/09
Filed: 1981-03-18
Abstract: PURPOSE:To obtain the flat frequency characteristics, by deciding the setting position of the  electrode of a piezoelectric plate so that a general offset is secured for the electric charge  induced on the electrode surface of the 1st resonance. CONSTITUTION:A metallic plate uses a phosphor bronze plate having 0.15mm. thickness, 15mm.  length and 8mm. width, and a piezoelectric plate made of the porcelain of zircon lead titanate  group with the same size is adhered on thesingle surface of the metallic plate. Then another  piezoelectric plate having 5mm. length with the same thickness and width as the first piezoelectric plate is adhered on the other surface of the metallic plate with their polarities set in the  same direction. Thus a piezoelectric bimorph oscillator is obtained. Then the end part of the  oscillator at the side where the shorter piezoelectric plate is adhered is fixed by adhesion to a case with 2mm. width, and a polyimide film having 28mm. diameter and 50mum thickness is formed  into a conical shape at the other end part of the oscillator. This cone of film is then joined to  the center of a diaphragm with its circumference end connected to the case. Thus a sound  generator is obtained. In such constitution, the positive electric charge produced to the short  piezoelectric plate offsets the negative electric charge produced to the long piezoelectric plate.  As a result, no peak part is caused to the output characteristics of the sound generator to  obtain the flat frequency characteristics.

Filed: 1994-03-11
Abstract: PURPOSE:To generate an alarm only in emergency wherein a communication path needs to be by-passed by setting the decision threshold value for alarming experientially based or an actual communication state. CONSTITUTION:The monitoring device 20 sets the initial setting TH (threshold value) of line quality SQD in a memory 27 and also sets the same value in a memory 26 as decision TH for SQD. Further, the same value is set in a modem 2. When operation is started, the line state is monitored in the modem 2, a monitor part 8 generates SQD, and an alarm generation part compares the obtained SQD with the initial setting TH. When SQD<= initial setting TH, an alarm is generated to inform the device 20. The device 20 compares SQD with the decision TH by a comparison part 24 and when SQD>= decision TH, an alarm is generated, but when SQD<= decision TH, an emergency alarm is generated. A decision part 23, on the other hand, inquires the state of a communication of a host 1, and when there is not communication abnormality, a decision alteration part 25 lowers the level of the decision TH in the memory 26 by one step.
