摘要： A control system for a variable displacement pump driven by a drive source for driving a vehicle is provided. The variable displacement pump pressurizes hydraulic oil, and is switchable between a full capacity operation in which a discharge flow rate is maximized and a partial capacity operation in which the discharge flow rate is lower than that in the full capacity operation. It is determined whether an operation for starting the drive source has been performed. A rotational speed of the drive source and a temperature of the hydraulic oil are detected. When the rotational speed of the drive source is equal to or higher than a predetermined rotational speed and the hydraulic oil temperature is equal to or lower than a predetermined temperature, immediately after the operation for starting the drive source is performed, the partial capacity operation of the variable displacement pump is performed. This control suppresses generation of untoward noises caused by the operation of the variable displacement pump when starting to drive the vehicle.

摘要： An insert clamped tool includes a tool holder, a cutting insert, a clamp and a pressing mechanism for pressing the clamp to urge the cutting insert against the bottom and the side walls of the insert-receiving pocket. The tool holder includes an insert-receiving pocket formed at a forward end thereof and having a bottom and side walls. The tool holder has an inclined surface sloping inward in a direction away from the insert-receiving pocket. The cutting insert is received on the insert-receiving pocket. The clamp is held into abutting engagement with the cutting insert. The clamp has a sliding face held in contacting engagement with the inclined surface of the tool holder.

摘要： A vehicle deceleration force control device of the invention reduces deceleration force (assist braking force) during implementation of engine brake assist control over a predetermined time (t2-t0) when a vehicle state is changed to an acceleration state by operation of an accelerator. A change amount of the deceleration force over time during reduction is limited to a predetermined value or less. This predetermined value is set to a larger value the steeper the road gradient during hill descent and is set to a smaller value the steeper the road gradient during hill climbing. The vehicle deceleration force control device enables smooth acceleration when shifting from deceleration to acceleration.
摘要翻译：本发明的车辆减速力控制装置通过加速器的运转将车辆状态改变为加速状态时，在规定时间（t2-t0）内实现发动机制动辅助控制时的减速力（辅助制动力）减小。在减速期间随着时间的减速力的变化量被限制在预定值以下。这个预定值被设定为较大的值，在山坡下降时道路坡度越陡，并且在爬坡期将道路坡度设置得越小越小。车辆减速力控制装置能够在从减速向加速度变化时平滑加速。

摘要： The vehicle deceleration control apparatus adjusts the assist braking force to be applied to each wheel, by adjusting each linear valve and pressure-reducing valve forming the brake system of a vehicle according to shift-position information transmitted from an AT ECU (Automatic Transmission Electronic Control Unit). Thus, generation of driver's unintended assist braking force is controlled, whereby drivability is improved.

摘要： An end mill is disclosed which includes a tool body having a shaft-like shape. The tool body has a cutting edge portion formed at one end thereof. The cutting edge portion has a plurality of circumferential cutting edges formed on the circumference thereof along the longitudinal axis of the tool body. The end mill is characterized in that the cutting edge portion has the circumferential surface thereof which includes rake faces and flanks. Each of the rake faces adjoins one of two adjacent circumferential cutting edges. Each of the flanks intersects with one of the rake faces at one end and adjoins the other of the two adjacent circumferential cutting edges at the other end. The rake faces have a rake angle arranged between a range of 5.degree. to -45.degree. at a cross section perpendicular to the axis of the tool body. The flanks have a relief angle arranged between a range of 20.degree. to 45.degree. at a cross section perpendicular to the axis of the tool body. In one embodiment, the circumferential surface of the cutting edge portion is formed of an alternately connected plurality of concave surfaces receding inwardly toward the center of the cutting edge portion, with different ranges of rake and relief angles.
