Filed: 1982-03-30
Abstract: PURPOSE:To improve the yield under mild conditions in obtaining the titled compound useful as a raw material for perfumes, etc. by condensing a gamma-lactone through the dehydration, by advancing the reaction in the presence of a strongly protonating catalyst in an inert solvent while removing the water formed by the reaction to the outside of the system. CONSTITUTION:A gamma-lactone of formula I (R<1> and R<2> are H or alkyl) is condensed through the dehydration. In the process, a water-insoluble inert solvent is used, and the gamma-lactone is heated in the presence of a sulfonic acid catalyst at 90- 230 deg.C while removing the water formed by the reaction to the outside of the system to give a 2-cyclopentenone of formula II. An aromatic hydrocarbon, e.g. toluene, is preferred for the water-insoluble inert solvent, and the amount thereof to be used is preferably 5-100pts.wt. based on 1pts.wt. raw material. p-Toluenesulfonic acid, methanesulfonic acid, etc. may be cited as the catalyst. The molar amount of the catalyst to be used is preferably 0.2-5 times of that of the raw material gamma-lactone. The reaction solution is treated by the ordinary method.

Abstract: PROBLEM TO BE SOLVED: To simplify a communication system for an interrogator and to improve the safety of communication by switching the connection lines set between a central controller and plural communication terminals and authenticating whether the communication terminals are proper or not. SOLUTION: A multiplexer 5 of a repeater 3 switches the connection lines set between the reader/writer units 21-2n and a PC(personal computer) 4. An authentication circuit 6 detects the authentication signals (rolling codes) which are transmitted from the units 21-2n and also authenticates the units 21-2n by these authentication signals. An arithmetic circuit 7 generates the authentication signals by applying the prescribed arithmetic processing f10() to the authentication signals received from the units 21-2n. Thus, the authentication processing is carried out between the units 21-2n and the repeater 3. The repeater 3 stores the authentication results of the units 21-2n in the circuit 6 and also transmits these results to the PC4 from the circuit 6.

Filed: 1983-03-29
Abstract: PURPOSE:To enable the controlling of frequency characteristics with a large freedom by laminating a plurality of ultrasonic vibrators sandwiching a delay material to regulate excitation amplitudes thereof. CONSTITUTION:A plurality of ultrasonic vibrators 1 are laminated sandwiching a delay material 6 as an impulse excitation is performed, the vibrator 1 with a smaller value of the registance 7 excite an ultrasonic wave with a larger amplitude level and hence, ultrasonic waves excited by the vibrators 1 are delayed the more in the time of arriving at the surface of a material to be detected, the closer to a backing material 3 the vibrators are positioned. The ultrasonic pulse to be the material being detected is synthesized allowed for the amplitude level and time delay. Thus, waveforms can be controlled by varying the value of resistance 7 providing for each vibrator 1 thereby increasing the freedom of the constant allowing the controlling frequency characteristics.
