Title: Microprocessor
Inventor: TSUBOTA MASASHI
IPC: G06F13/42
Filed: 1990-06-21
Abstract: PURPOSE:To attain the application of an existing external input/output (I/O) device despite a high speed clock frequency or the replacement of CPU boards by setting the recovery time in accordance with the I/O device. CONSTITUTION:An inactive state where no bus access is carried out is repetitively inserted after the end of the first I/O access in the continuous I/O accesses. The frequency of the inactive state is counted by a counter circuit 101 and then compared with the value of a recovery register 102 by a comparator 103. When the coincidence of the comparison is secured, a recovery end signal 111 is outputted for start of the next I/O access. Thus the recovery time is set in accordance with an I/O device. Then an existing I/O device can be applied as it is, and the memory access is never affected at all since the recovery processing frequency is equal to the number of continuous I/O accesses.

Filed: 1986-07-16
Abstract: PURPOSE:To prevent the deviation of a picture in case of multiple recording by changing scanning speed magnifications in main scanning/subscanning directions of an original read means independently at the time of each picture recording. CONSTITUTION:A VIDEO signal with a different magnification from that at a 1st time is transferred from a reader section R to a printer section P in a 2nd recording. In storing known degrees of paper shrinkage alpha in advance, the scanning speed v2 of the optical system at the 2nd recording is expressed as v2=v1/alpha and the clock rate f2 is expressed as f2=alphafl, where v1 is the scanning speed of the optical system at 1st recording and f1 is the clock rate at the 1st recording. Furthermore, let the turning speed of a photosensitive drum 7 be (v) and the scanning speed magnification A in the sub scanning direction is expressed as A=v/v1. Thus, the deviation of the picture at every recording due to the shrinkage of the paper in case of multiple recording is minimized.

Title: Photometric control system of single-lens reflex camera
Inventor: TSUNEKAWA TOKUICHI
IPC: G03B7/081
Filed: 1980-11-25
Abstract: PURPOSE:To select photometric distribution optionally and to prevent improper exposure by discriminating the difference between the 1st arithmetic output adjusted by a photometric distribution setting member and the 2nd arithmetic output. CONSTITUTION:The outputs Bv(A) and Bv(S) of an averaged light measuring circuit LM1 and a spot light measuring circuit LM2 are divided internally by a slide terminal BRS adjusted by a photometric part setting member to obtain the 1st arithmetic output and the 2nd arithmetic output which has a 1 internal division ratio. The difference between both the arithmetic outputs is found by an operational amplifier OP2 and when it exceeds a prescribed value, an OR gate OR1 has a level H to turn on an analog gate G2 and to turn off an F1. Consequently, exposure control is exercised by the 2nd arithmetic output. When the difference is below the prescribed value, an L-level OR gate output is generated and while the F2 turns off, the F1 turns on, thereby performing the control by the 1st arithmetic output.
