Title: Detector for position of maximum in-cylinder pressure
Inventor: MORITA TATSURO
IPC: F02D45/00
Filed: 1987-01-23
Abstract: PURPOSE:To detect the crank angle at which the pressure in an air cylinder is maximum by providing an internal air cylinder pressure detecting means, a crank angle detecting means, a load detecting means, a maximum internal cylinder pressure detecting means, a detecting means for its position, a normalizing means, and a correcting means. CONSTITUTION:An internal cylinder pressure sensor (a) detects the maximum value of the pressure in a cylinder in a specific section. The crank angle at which the pressure in the cylinder is maximum is detected (b) and the maximum position of the pressure in the cylinder in a current combustion stroke is detected (e). Then the maximum value of the pressure in the cylinder in the specific section is normalized according to an engine load (c) and a coefficient of the normalization is calculated (f). When the coefficient of normalization is within a specific range, the output of the maximum position detecting means (e) is determined as a final internal cylinder pressure maximum position and when not, the last value is determined as the final internal cylinder pressure maximum position to perform correction (g). Consequently, the crank angle position at which the air cylinder internal pressure of the engine is maximum is detected to preclude knocking and also control the ignition period where the maximum torque is obtained.

When the already reaped region is placed on the left side, the leave of the grasses or turf grasses on the right side based on the travel direction of the vehicle are judged to be long, and the left light and the right light are turned off and on, respectively. Or whether the leave of the grasses or the turf grasses are long on any of the right and lift sides based on the travel direction of the vehicle is judged from the state of heights of the leave of the grasses or the turf grasses memorized in a memory, and a light on the side having the long leave is turned on. Thereby, the changes of brightness in the boundary part between a worked region and a non-worked region can be highlighted and imaged to surely detect the boundary.

When the sheet is set and pressurized, by a spring 21a for pressurization, the sheet is pressurized by a paper feeding roller 29 and it comes to be possible to feed the sheet. When the sheet is gone, the intermediate plate 3 and the pressurization arm 19a respectively move to B, B' positions. At the time of changing over of the spring for pressurization, when a storage cassette 1 is taken out of a picture image formating device main body, the pressurization arm 19a moves to a C' position of a stopper 25, and it comes to be possible to optional springs 21b-d for pressurization by sliding of the slide shaft 13. Consequently, it is possible to set pressurizing force suitable for various paper size.

IPC: F16H9/12
Filed: 1985-02-01
Abstract: PURPOSE:To prevent temp. rise of members by allowing external air to flow into the weight accommodation space, and by cooling the weight and movable pulley plate. CONSTITUTION:The weight accommodation space S is put in communication to outside through a gap g provided between the periphery of a cam member 9 and the internal edge of a movable pulley plate 6b, and thereby external air is introduced into the weight accommodation space S. This enables direct contact of external air the the weight 8 and the back face of the movable pulley plate 6b, and thereby the heat can be conducted to the external air for cooling. Because the heat of V-belt 7 is conducted to the cooled pulley plate 6b, the V-belt 7 is cooled at the same time. Accordingly such members as weight 8 and V-belt 7 are prevented from bearing high temperature.
