Title: Drive device
Inventor: HAGIWARA MAKOTO
IPC: F16D48/02
Filed: 1985-09-06
Abstract: PURPOSE:To prevent both drive shafts from the inability to rotate by inter locking a clutch device mounted between the drive shafts and a hydraulic operating mechanism for controlling the clutch device with each other so that at least one of the drive shafts is maintained under the power transmitting condition. CONSTITUTION:When a left electromagnetic coil 26 is turned off for example and a right electromagnetic coil 27 is turned on for example, a left pressure chamber 17 of a spool 14 is compressed with a right rod 21 pressed by the electromagnetic coil 27, while a right pressure chamber 18 is extended. Then, a right concave groove 23 closes communication to a pressure supply source 28 and cmmunicates to the atmospheric pressure side liquid tank 29. Thus, pressure in a clutch cylinder 16 is reduced to turn off said cylinder. However, since said groove 22 is left communicating to said source 28, the clutch cylinder 15 is left turned on and a drive force is transmitted to a left drive wheel 11a through a left rotary shaft 11. On the other hand, in the case reverse to such condition, a right drive wheel 12a is rotated through a right drive shaft 12.

The circuit 6 switches the output signal of the circuit 7 and that of the circuit 3 and outputs the result to a binary frequency divider circuit 5. Moreover, a variable frequency divider counter circuit 8 counts the output signal of the variable frequency divider circuit 4 and sends switching control information of the switch 6 to the circuit 9 with a frequency division ratio set by the logic circuit 9. That is, the circuit 8 counts the output number of the output signals of the circuit 4, when the count is equal to a prescribed value, the output signal of the circuit 3 sends the control information of the switch 6 to the circuit 9 so that the output signal of the circuit 3 is an input signal to the circuit 5. The circuit 9 sends the switching signal to the switch 6, and sends a signal to set the frequency division value of the circuit 3. Thus, a prescribed frequency division value is set other than an integer number without incurring a complicated circuit.

Title: Picture reader and white criterion reading method
Inventor: MAKI YOICHIRO
IPC: H04N1/401
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To provide a picture reader which can easily read high-quality pictures without increasing the cost and a white criterion reading method. SOLUTION: In a white criterion reading method, the white criteria of a plurality of lines are read in a subscanning direction with respect to each image pickup element of a line sensor and an averaging section 21 of a white criterion setting section 20 averages first and second line groups corresponding to both end sections of the read white criteria in the subscanning direction. Then a comparator circuit 22 compares the average values with each other and a setting circuit 23 sets the larger average value as white criterion data. Consequently, even when a white criterion plate is contaminated with dust or scratched, the dust-and scratch-free portions of the criterion plate can be fetched as the white criterion data, because the possibility of the existence of the dust and scratches over both end sections of the plate is extremely low.  Therefore, the set white criterion data become equivalent to the original white criterion value and the S/N can be improved by reducing noise components.
