Abstract: An excellent waveform signal with less jitter is obtained as an output signal from a reproducing optical pickup, irrespective of a relative reading speed. Thus there is no need for an equalizing circuit on a reproducing apparatus side. An input bit sequence or a recording NRZI signal is combined with spatial frequency characteristics G(fs) by a G(fs) converter. An output signal from the G(fs) converter is combined with equalizing frequency characteristics EQ(fs) necessary on a reproducing side by an EQ(fs) converter. An output from the EQ(fs) converter is saturation-amplified by a saturation amplifier, thereby producing an ideally pre-jittered recording signal that has equivalent enhanced high-frequency component. The recording signal is recorded on an optical disk.

Accordingly, the fall of temperature of warm water in the tank by the newly supplied water is prevented, and it is possible to dispense warm water having appropriate temperature at any time.

Abstract: In an infra-red surveillance system, a digital memory (1) has a storage location for each of a number of zones, defined by azimuth and elevation co-ordinates, the zones together covering 360.degree. in azimuth and 20.degree., for example, in elevation. In each location there is stored a data word built up from the responses on a zone in successive scans. Each word can be read into a decoder (5) which selects an appropriate video display level in the form of a two-bit word which is then stored in a buffer store (6). A buffer store data controls the display on a cathode ray tube (2). A manually controlled cursor circuit (8) generates a cursor address which results in a cursor display at the corresponding position on the cathode ray tube. The display is in the form of four strips, one above the other, each representing a quadrant of azimuth.
