Abstract: PROBLEM TO BE SOLVED: To manufacture a photographic lens using a common lens and a common control system and having different zoom specification and to provide a camera capable of inexpensively realizing zoom control that the lens is accurately stopped at a zoom end in each specification. SOLUTION: In this camera, zoom position information based on the number of pulses is obtained by a zoom information detection part 6, and a silver seal is stuck to be laid to a 2nd telephoto position at two telephoto ends (1st telephoto position and 2nd telephoto position), then the output of the detection part 6 is changed when the detection part 6 passes through the silver seal. The end (a) of the silver seal on a wide side and the end (b) of the silver seal on the 1st telephoto side are set as the reference of an absolute stop position. A distance to the 2nd telephoto position is converted as the number of pulses with the end (a) as reference. By counting the specified number of pulses after detecting the end (a), the lens exactly reaches the 2nd telephoto position.  In the same manner, a distance to the 1st telephoto position is converted as the number of pulses with the end (b) as reference. By counting the specified number of pulses after detecting the end (b), the lens reaches the 1st telephoto position.

Title: Device for controlling speed change at braking of transmission with infinite gear ratio
Inventor: NISHIO MOTOHARU
IPC: B60W10/18
Filed: 2001-01-17
Abstract: PROBLEM TO BE SOLVED: To prevent a stall, even when wheels are locked before a transmission with infinite gear ratio completes a gear shift to a neutral position through quick braking. SOLUTION: When a gear ratio reaches a rotation synchronizing point by braking (a brake switch 47 is turned on) at an instant t1 and a command to switch from a direct connection mode to a power circulating mode is generated, a high clutch is made to be released, but a low clutch is prevented from engaging. The transmission is brought to neutral position by prohibiting engagement of the low clutch as well as switching the high clutch from engagement to releasing for preventing engine stall due to gear shift lag to the neutral position, even if the wheels are locked at braking. During this time, a target CVT gear ratio icvto is controlled, such that the relative rotation of the low clutch becomes zero. These controls are completed, when the state becomes accelerator pedal stepped state (after an instant t3) to open a throttle opening TVO.  Then the low clutch is allowed to be engaged for preventing re-engagement shock of the low clutch, since the relative rotation of the low clutch becomes zero.
