Abstract: A living body monitoring activity system detects major activities, or feeble living body activities. In a method for monitoring existence of human movements or living body activities in living environments (e.g., sleeping activities involving a bed, a Futon-mat, a pad, or a Tatami-mat), an optical fiber type flat shaped body sensor including an optical fiber affixed or fitted to a flat shaped body is used, and light is emitted into the optical fiber from a light source, and changes of polarized wave conditions of light propagating in the optical fiber are brought about by changes in form of the optical fiber type flat shaped body sensor caused by human movements or living body activities and are detected by a measuring apparatus for polarized wave fluctuations so human activities or movements are discriminated based on the detected value of the polarized wave fluctuations.

Abstract: A power take off device for an automatic transmission for taking off auxiliary power has a power take off switch which turns on the power take off device. The automatic transmission includes a torque converter and a lock-up clutch. The torque converter is connected to the power take off device when the power take off switch is turned on. The automatic transmission includes a lock-up control valve operating the lock-up clutch and a 1-2 shift valve for changing gear speed from a first stage to a second stage. The 1-2 shift valve supplies line pressure to the lock-up control valve when the shift lever is in the neutral position or the parking position and cuts off line pressure supplied to the lock-up control valve when the 1-2 shift valve is in the first stage.

Abstract: A control device of an automatic transmission comprises a controller which detects accel off caused by the release of accelerating owing to the accel stamping in which lock-up clutch is released, and which proceeds command which releases the operation thereof or releases temporally the operation thereof to an exhaust brake device when it is decided that the exhaust brake is in operation. When accel off is suddenly conducted at the time of accelerating in which the lock-up clutch is not engaged the phenomenon in which the speed ratio at the torque converter is prevented from occurring by releasing the exhaust brake by the controller. Accordingly, the engaging operation of the lock-up clutch is conducted easily and it is possible to let the engine brake work. When the down shift of the automatic transmission or accel off is conducted a the time of using the exhaust brake, it is possible to conduct the engagement, of the lock-up clutch easily and let the engine brake work effectively.
