摘要： An off-hook signal and dial pulse generating circuit which has a smaller number of switching devices having a high withstand current characteristic and has a less surge voltage than up to now. A dial pulse circuit and a switch block circuit are connected in parallel with the output side of a full-wave rectifying circuit. The circuit comprises an impedance circuit and a first switch circuit to be turned on/off by a signal. The impedance circuit operates in a state where it has an inductance component in case that a signal synchronized with a signal is off and operates in a state where it has no inductance in case that the signal is on, and an electric current flowing therethrough is turned on/off by the first switch circuit. The circuit comprises a series circuit composed of second and third switch circuits. The second switch circuit is turned on/off in response to a signal synchronized with the signal (where this circuit is off when the signal is on). The third switch circuit is turned on/off in response to the signal.

摘要： In a high voltage detection circuit, a high voltage detection portion 10 constituted with, for instance, two constant voltage circuits 10a and 10c and a current mirror portion 10b, a strobe input 20 and an output communication device 30 are provided. This high voltage detection circuit outputs a high voltage detection signal S30 if an input voltage Vin, which is equal to or greater than a voltage value set by the constant voltage circuits 10a and 10c is supplied while a strobe control signal ST is provided. When high voltage detection on telephone lines is performed by such a high voltage detection circuit by inputting the results of the detection of a polarity inversion at telephone lines as a strobe control signal ST, only reception of bell signal can be detected. In addition, by resetting the results of polarity inversion detection using the results of high voltage detection, it is possible to identify a non-ringing reception that is not accompanied by a bell signal.

摘要： A novel lactase having a molecular weight of about 3.times.10.sup.5, an optimum pH value of about 6.0, an optimum temperature of about 60.degree. C. and at least 1 of the ratio of the activity for hydrolyzing lactose to the activity for hydrolyzing a synthetic substrate: o-nitrophenyl-.beta.-D-galactopyranoside (Lact/ONPG ratio), which is produced by cultivating a microorganism of the genus Bacillus being capable of producing the enzyme, particularly Bacillus circulans LOB 377 (ATCC No. 31382) and isolating from the culture broth. This novel lactase is characteristic in the excellent thermostability and the high Lact/ONPG ratio and hence is useful for treating milk and milk products as well as for preventing diarrhea due to lactose intolerance, especially in babies and infants.
