Title: Radiant energy detecting device
Inventor: FUSE MASAO
IPC: G01J1/42
Filed: 1984-12-06
Abstract: PURPOSE:To know a position of a radiant energy source by providing a rotary drum, a radiation detector, an incident position detecting means, and a discriminating means for discriminating which zone the radiant energy source is positioned in. CONSTITUTION:Radiant energies L1-L5 reflected by reflection mirrors M1-M5 are irradiated in parallel roughly onto an (l) line in the longitudinal direction of a rotary drum 2. Opening O1-O5 of the rotary drum 2 come successively onto the (l) line, therefore, only one opening is always positioned on the (l) line, and the radiant energy L3 is made incident on a radiation detector 3 from the opening O3. In this way, when the rotary drum 2 rotates, the openings O1-O5 reach successively on the (l) line. When there is a radiant energy source in one of each zone Z1-Z5, its radiant energies L1-L5 are reflected by reflectors M1-M5, and when the corresponding openings O1-O5 exist on the (l) line, they are made to pass through them, made incident on the detector 3, and an output signal is generated. In this case, an incident position detector 4 also detects which opening has come to the (l) line, and a discriminating means 5 discriminates from which zone the radiant energy has come.

Title: Synchronizing clock generating circuit
Inventor: TAKETOMI HISASHI
IPC: H04L7/033
Filed: 1991-09-10
Abstract: PURPOSE:To preliminarily avoid an unexpected state by providing another filter different from a loop filter by time constant and generating a clock switching signal at the time when the difference value between output signals of these filters exceeds a threshold indicating the clock switching and allowing lower-order devices to detect that the clock is switched. CONSTITUTION:When an input clock is switched, the output voltage of a phase comparator 1 is generated in accordance with the phase difference. That is, the output voltage is larger according as the phase difference is larger, and the output voltage is smaller according as the phase difference is smaller. Since filters 2 and 20 which receive this output voltage of the phase comparator 1 have different time constants, the voltage difference is gradually increased till arrival at an input voltage (the output voltage of the comparator 1) when the output voltage of the phase comparator 1 is increased by the increase of the phase difference due to switching of the input clock. Consequently, an abnormality detecting circuit 4 generates the clock switching signal when the voltage difference of time constants is large enough to indicate the clock switching.

Title: Still video camera
Inventor: TAMURA TOMOAKI
IPC: H04N5/225
Filed: 1987-10-15
Abstract: PURPOSE:To prevent a video floppy during magnetic recording from being ejected by blocking the eject of the eject operating member of the video floppy while a finder is being projected. CONSTITUTION:While the finder 4 is projected and a lock member 4b blocks the horizontal movement of a lock release member 8, the eject operation member 5 is moved to the left to disable the floppy to be ejected. Thus, in order to eject the floppy, the finder 4 is depressed down to the storage position to bring the camera in the non-pickup state and the engagement of the lock 4b with the lock release member 8 is released to release the blocking of the lock release member 8 to the left. Thus, the eject of the floppy during magnetic recording is prevented completely.
