Title: Heating device
Inventor: ITOU MASAO
IPC: H05B6/68
Filed: 1982-09-10
Abstract: PURPOSE:To maintain an even speech level which is inputted from a microphone no matter how remote a speaker and the microphone are located for thereby accomplishing an invariably stable speech recognition, by providing the front surface of heating device with a distance detecting sensor adapted to detect a distance between the speaker and the microphone and a gain control means adapted to control the magnitude of amplification of speech input section responsive to an output signal from a distance detection means consisting of the sensor and an amplifier. CONSTITUTION:A gain control means 26 functions to rectify and smooth an output signal from a distance detecting means 24 for a diode D, a resistor R1 and a condenser C. The signal thus smoothed drives the LED of photocoupler 27 for varying the resistance layer of CDS. The CDS is connected with the resistor R of AMP 2 of speech input means 20 in parallel, and has its resistance value increased for thereby causing a speech input section 20 to increase its magnitude of amplification when, as for instance, a focusing type infra-red ray sensor is used, because a smoothed signal is of small magnitude and the flow of electric current to the LED is marginal. On the contrary, when the distance is short, the smoothed signal is of large magnitude and a greater amount of electric current flows to the LED for reducing the resistance value of CDS, thereby bringing down the magnitude of amplification for the speech input section 20.

IPC: A61M25/00
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To reduce the diameter of a tube of a catheter with a balloon and to reduce the number of necessary parts. SOLUTION: This catheter with the balloon has a double tube type structure consisting of an inner tube 3 and outer tube 4 with which a tube 1 is slidable. The one end of the balloon 2 is fixed to the side of the inner tube 3 and the other end thereof is fixed to the side of the outer tube 4. The bending moment of the inner tube 3 is set in a range where the inner tube 3 has necessary rigidity, i.e., in a range of 20 to 70 g.cm. Consequently, the balloon may be elongated and diametrally reduced and the air venting of the balloon without an air vent tube is made executable by advancing the inner tube 3 relative to the outer tube 4 without a pipe for extension and, therefore, the diameters of both tubes 3, 4 may be reduced and the diameter of the tube 1 may be reduced. The number of the necessary parts may be decreased by dispensing with the pipe for elongation and the air vent tube.

Abstract: PURPOSE:To realize a small-size and low-cost monitor equipment by giving two different threshold levels to the differential amplifier according to the circuit which is under starting or not and then giving monitor to the next subscriber circuit. CONSTITUTION:In case the circuit is not started, contacts 21a and 21b are opened with contact 21c closed respectively; while these contacts become contrary each when the circuit is started. In other words, the bias voltage level of bias circuit 23 varies according to contacts 21b and 21c turned on or off in response to the loop starting signal. And the threshold voltage of differential amplifier 24 features a comparatively high level when the called subscriber is under the idle or blocked state and then a comparatively low value in case the called subscriber is under starting each. While potential difference Vd between channels 11a and 11b varies according to the state of the called subscriber: the idle state; the on-hook state with starting; the off-hook state; and the blocked state each. Thus the monitoring becomes possible for next subscriber circuit 3' by making the output of amplifier 24 plus the signal sent from contact 21d showing the starting or nonstarting state pass through logic circuit 27.
