Title: Recording and reproducing device
Inventor: KOBAYASHI MASAAKI
IPC: G11B20/06
Filed: 1984-06-20
Abstract: PURPOSE:To perform narrow-band transmission and to obtain a good-S/N playback signal by recording an input signal after frequency modulation of carrier frequency higher than the highest frequency, and multiplying the frequency-modulated wave substantially by four for demodulation during reproducing operation. CONSTITUTION:The input signal is inputted to an input terminal 1 and converted into an FM wave by a voltage-controlled oscillator 2. The carrier frequency of the FM modulated wave is set higher than the maximum frequency of the input signal and this FM wave is recorded on a magnetic tape 4 through a magnetic head 3. The FM signal recorded on the tape 4 is reproduced by a magnetic head 5 and the reproduced FM wave is supplied to a four-multiplication type demodulator 6. The demodulator 6 consists of a 90 deg. phase shifter 8 composed of a transversal filter and an FM demodulator 11 which is connected to the phase shifter 8 and multiplies signals from input terminals 12 and 13 by two to perform substantially four multiplication, and the output of the demodulator 6 is supplied to an output terminal 7. Thus, narrow-band recording and reproduction are performed and the S/N is improved.

Title: Film image reader
Inventor: OGOSHI TAKESHI
IPC: H04N5/253
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To obtain an image with high quality in a short time by revising an exposure time to be a prescribed time when the calculated exposure time exceeds the prescribed time to compress an input level. SOLUTION: A gamma LUT section 73 is made up of a memory, in which N/P inversion and gamma conversion of G, R, B signals are conducted. A data arithmetic section 204 uses image data or the like sent from a film scanner 100 to calculate a ratio of a calculated exposure time to a prescribed time when an exposure time of a CCD 2, an analog gain of an amplifier section 3 and the calculated exposure time exceed the prescribed time. When a film 13 is a negative film, table data to be set to the gamma LUT section 73 are calculated for N/P inversion and gamma conversion. In the case that the calculated exposure time exceeds the prescribed time, when the table data of the gamma LUT section 73 are calculated, an input level of the data is compressed by the ratio and the exposure time when an image is received is set to be the prescribed time.

Filed: 1981-08-17
Abstract: PURPOSE:To confirm the normalcy of a stand-by system without interrupting control operation by deciding that a switchboard is not sending a dial tone to any of extensions and then switching systems. CONSTITUTION:If a fault occurs to an ACT system processor or main storage device, a fault monitoring system switching circuit 1 detects that, and sends a control signal 11 to an SBY system processor to start processing as an ACT system and slao changes ACT system specifying signal to a channel controller. In this case, when the processor specified newly as the ACT system is an SBY system, control over the channel device 7 is to be started by call data transferred from the ACT system processor, but the halfway result of the counting of dial pulses, etc., is not transferred to the SBY system, so system switching operation is started on the condition that there is no extension receiving a dial tone.
