Abstract: An automatic telephone answering and recording device, wherein if an incoming call is received when an incoming message tape is full or an owner fails to set the telephone answering device to an automatic answering mode prior to leaving, the telephone line is nevertheless engaged to operate the telephone answering device. Then an outgoing message for answering only, such as "Please call back later", is generated by a voice synthesizer and sent out to a calling party, so that the calling party can understand the situation and know what to do.

Abstract: An electrolytic apparatus for applying a voltage to a workpiece (1) and a counter electrode (5) both immersed in an electrolyte (3) contained in a vessel (4) thereby processing the workpiece (1) comprises a voltage source (15, 15') for applying voltage between the workpiece (1) and the counter electrode (5) in the form of pulses whose polarity is periodically changed, a beam generator (16) for irradiating a subsidiary energy beam (17) on a selected region of the workpiece (17) by generating the beam (17) in the form of periodic pulses and a timing control device (21) for synchronizing the periods of the voltage pulses and the beam pulses.
