Title: Capacitance type seating detector
Inventor: TOYOFUKU MASANORI
IPC: A47K13/24
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To surely detect seating at all times by providing a first electrode and a second electrode for constituting a capacitor for detection for detecting the change of capacitance by seating over the almost entire area of a seating part while keeping an almost fixed feeling. SOLUTION: The first and second electrodes 23 and 24 for constituting the capacitor 63 for the detection are arranged side by side and disposed within the almost same surface of a toilet seat with a narrow interval. At the time of seating from a non-seating state, the capacitance of the capacitor 63 for the detection of a resonance circuit 33 rapidly becomes large, the resonance frequency of the resonance circuit 33 becomes lower than the oscillation frequency of an oscillation circuit 32 and the output voltage of a rectifier circuit 35, that is the output voltage of an OP amplifier 36, steeply declines simultaneously with seating. To the contrary, since a reference voltage Vcom gradually drops by the time constant of a compensation circuit 38, the output voltage Vdel of the OP amplifier 36 is turned to the relation of Vdel <Vcom simultaneously with seating.  Thus, the output voltage Vout of a comparator circuit 37 becomes a high level simultaneously with seating and thus, seating is detected.

Abstract: PURPOSE:To reduce the trouble of dialing operation by dialing the facsimile number or telephone number of an opposite party and then automatically sending the other number of the opposite party, and enabling a facsimile communication and a telephone call in parallel by using two lines. CONSTITUTION:Correspondence information on opposite-party facsimile (FAX) numbers and telephone numbers is stored in a system memory 6 and the opposite-party FAX number is inputted from a dial number input means 5 to start the communication operation of the device. Then a network control unit 2 uses a telephone line A to dial the FAX number and the specified FAX communication is started when there is an answer. Then when a communication mode setting means 5b already sets a double mode, a system control part 7 retrieves the telephone number corresponding to the FAX number in the memory 6 and calls the corresponding telephone number through a network control unit 4 by using a telephone line B and starts the telephone call when there is an answer. Consequently, the trouble of dialing operation is reduced and the communications are made efficiently.

CONSTITUTION:When the instruction of the conversion is inputted, a converting means 2 converts the reading information, which are inputted from an input means 1, to the word including the KANJI corresponding to the reading information. When the word is used for a sentence under preparation after the conversion and the instruction of storage is not inputted from the input means 1, the word is stored in a first memory area 3a of a storing means 3 by a first storing means 4. When the instruction of the storage is inputted from the input means 1, the converted word is stored in a second memory area 3b of the storing means 3 in the state that the word is not erased for the desired period by a second storing means 6. Thus, since the stored word is not erased, the learning function can be improved.

Abstract: PURPOSE:To prepare a highly pure bisphenol by recovering water and a phenol from the reaction product of the phenol with acetone, adding a solvent, subjecting to an azeotropic distillation under vacuum, removing the solvent from the distillation product and, if necessary, further washing. CONSTITUTION:A phenol is reacted with acetone in the presence of an acidic catalyst (e.g. hydrochloric acid) and the reaction solution is neutralized with a base at 60-65 deg.C to a pH of 3.5-4.0. The water layer is removed from the neutralized reaction solution and the phenol is recovered up to the inner temperature of 160-170 deg.C. The remained solution is mixed with an azeotropic solvent (e.g. an alkylbenzene) and azeotropically distilled under vacuum. A bisphenol crystallized in the azeotropic solvent is separated and washed with benzene, etc., to provide the highly pure bisphenol. The azeotropic solvent is again employed. The azeotropic distillation permits to provide the objective compound without producing thermally decomposed products.
