    Abstract: A method and an apparatus for generating vacuum pressure in an engine is disclosed. The engine includes an intake path, combustion chambers and an exhaust path. Airflow in the intake path is controlled by a throttle valve. An exhaust gas recirculation (EGR) passage deflects a part of flow of the exhaust gas to the intake path from the exhaust path. An EGR valve regulates the flow of exhaust gas passing through the EGR passage. A brake booster is connected to the intake path and increases braking force of the vehicle. A pressure sensor detects the pressure in the booster. A central processing unit determines whether the detected pressure is higher than a predetermined value. The throttle valve is in a relatively open position when the engine performs stratified charge combustion. The throttle valve decreases the pressure in the intake path when the throttle valve restricts flow. The CPU controls the throttle valve to decrease the pressure in the intake path when the booster pressure is higher than the predetermined value and actuates the EGR valve to decrease the gas flow in the EGR passage. This results in better brake and engine performance.

    Abstract translation: 公开了一种在发动机中产生真空压力的方法和装置。 发动机包括进气通道，燃烧室和排气路径。 进气道中的气流由节流阀控制。 排气再循环（EGR）通道将废气流的一部分从排气路径偏转到进气路径。 EGR阀调节通过EGR通道的废气流。 制动助力器连接到进气道并增加车辆的制动力。 压力传感器检测升压器中的压力。 中央处理单元确定检测到的压力是否高于预定值。 当发动机执行分层充气燃烧时，节流阀处于相对打开位置。 当节流阀限制流量时，节流阀减小进气通道中的压力。 当增压压力高于预定值时，CPU控制节流阀以减小进气通道中的压力，并致动EGR阀以减少EGR通道中的气流。 这导致更好的制动和发动机性能。

    Abstract: A plurality of ribs are provided on a cut paper discharge guide and an upper cover which define a discharge port for discharging a cut paper. The ribs hold a cut paper in width direction. Even if a cut paper having a high degree of curl is supplied when a roll diameter of a roll paper is reduced, it is possible to prevent a paper jam such as falling or clogging of the cut paper. It is desirable that the ribs provided on the cut paper discharge guide and the upper cover are disposed in an alternate pattern along the width direction of the discharge port. This arrangement is particularly effective in a printer having an inclined paper passage.

    Abstract: A printer including a lower frame on which roll paper is loaded, a cutter section mounted above the lower frame for cutting the roll paper on which printing is made, and a cover that allows a front of the lower frame to be opened and closed is provided. A slope portion for causing paper dust or a slip of paper, which falls from the cutter section, to slip down toward the front of the lower frame is provided at a portion of the lower frame below the cutter section. The cover is provided with a pocket portion for receiving the paper dust or the slip of paper slipping down on the slope, and the pocket portion is adjacent to the lowest portion of the slope portion when the cover is closed.

    Abstract: In a printer which prints on a roll paper transported toward a discharge port and cuts the roll paper, an exchangeable lower cover is attached to the printer. The exchangeable lower cover defines a lower edge of the discharge port. A change of height of the discharge port is allowed by exchanging the exchangeable lower cover for another one. Hereby, it is possible to change specifications between one for holding a printed slip and the other for allowing the printed slip to fall freely. In the former specification, a brush provided at a periphery of an upper edge of the discharge port is in contact with a lower cover. On the other hand, in the latter specification, the brush is in distant from another lower cover.

    Abstract: A movable blade unit is fixed to a cutter release lever. The cutter release lever is attached to an upper frame by a cutter supporting point shaft so as to freely oscillate. A latch lever holding the upper frame at a closed position and a cutter lock lever locking the cutter release lever are integrated, and are coupled by an opening and closing lever. If the opening and closing lever is pushed down, the cutter lock lever cancels the lock of the cutter release lever while keeping a state in which the latch lever latches the upper frame. Accordingly, in the movable blade unit, a driving force transmission path between the movable blade unit and a cutter driving motor is disconnected, and a movable blade is returned to a home position by a return spring.
