Title: Multiplexing information signal recording and reproducing method and its recording device
Inventor: TSUTSUMI MASAHITO
IPC: H04N9/85
Filed: 1986-07-03
Abstract: PURPOSE:To record and reproduce a video signal with a wider frequency band by adding the higher frequency component of a video signal to an existing recording and reproducing system corresponding to the transmission frequency band of a recording medium or recording and reproducing device. CONSTITUTION:the luminance signal of wide frequency band filtered and separated by a comb-line filter 2 is respectively supplied to a low-pass filter(LPF) 3 and a high-pass filter(HPF) 4, and the frequency band of said signal is halved with a boundary frequency fM which is set at 3MHz. The lower frequency band of the luminance signal shown as YL taken out from the LPF 3, has the same frequency band(0-3MHz) as that of a band limited luminance signal, while the higher frequency band YH of the luminance signal taken out from the HPF 4 is separated and filtered by an LPF 19 to come with a frequency band YH' which is 4.02-6.22MHz, and thereafter is supplied to an adding circuit 20. As a result, the recording and reproducing of a video signal with a broader frequency band can be executed as maintaining the interchangeability with the existing recording and reproducing system.

Title: Cache memory system
Inventor: SASAKI TORU
IPC: G11C11/401
Filed: 1988-06-27
Abstract: PURPOSE:To attain the high speed of data processing by using SRAM at a memory area to require the high speed of an access speed, using DRAM at the memory area to require the enlargement of a capacity and constructing a cache memory system. CONSTITUTION:An address read out of a tag memory part 17 is compared by a comparator 19, and at the time of coincidence, the data from a data memory part 15 are confirmed to be the desired data, a bit signal is given to a control logic 21 and a condition signal is given to an MPU. At the time of anti-coincidence, an error signal is outputted and the desired data, which are not stored into the data memory part 15 for a main memory, are accessed. Since the tag memory part 17 requires the high speed and the data memory part 15 needs the large capacity, the data memory part 15 is composed of the DRAM and the tag memory part 17 is composed of an SRM. Thus, the high speed of the data processing is attained.

IPC: H04N5/235
Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To immediately execute next photographing operation and also to always acquire an image signal expressing an image by appropriate exposure by allowing an exposure permission signal generating means to transmit an exposure permission signal when a charge control circuit judges that the charge current of a flash light generating device is equal to or less than a specified level. SOLUTION: In stroboscope charging processing, a CPU 29 controls an MC voltage measuring circuit through a stroboscope control circuit 35, and monitors the charge voltage of a main capacitor. By measuring the voltage of the main capacitor, a current quantity flowing into a DC/DC converter at that time is confirmed. When the current quantity flowing into the DC/DC converter and the current quantity flowing in the main capacitor are decreased, electric noise made by the DC/DC converter itself is also reduced. Then, the CPU 29 being the exposure permission signal generating means generates the exposure permission signal when the current quantity flowing into the DC/DC converter is equal to or less than the specified level.
