摘要： A handheld engine-driven cutter is provided with a disk blade and a main body that drives the disk blade. The main body comprises a four-stroke engine, an oil supplying opening from which engine oil is supplied, and an oil exhausting opening from which the engine oil is exhausted. In this engine cutter, the oil supplying opening and the oil exhausting opening are both disposed on one side of the main body where one end of a driving axis of the four-stroke engine is located.

摘要： The present invention relates to a fuel cell system in which a high-pressure gas supply tube is connected to a gas supply opening of a fuel cell, a gas pressure regulating valve is installed in the middle of the high-pressure gas supply tube, and upstream-side and downstream-side shut-off valves are provided respectively on the upstream side and the downstream side of the gas pressure regulating valve in the high-pressure gas supply tube. The fuel cell system is activated by opening the upstream-side shut-off valve and thereafter opening the downstream-side shut-off valve. In the fuel cell system, there has been a problem that when the upstream-side shut-off valve is opened and thereafter the downstream-side shut-off valve is opened in a state in which the upstream side of the downstream-side shut-off valve on the hydrogen supply tube is not sufficiently pressurized, high-pressure gas which passes through a throttle section of the hydrogen pressure regulating valve causes pulsation in the supply tube, producing a loud noise. The present invention is to solve the above problem by providing, in the fuel cell system, control means for delaying the timing for opening the downstream-side shut-off valve (33) by a predetermined time period with respect to the timing for opening the upstream-side shut-off valve (31) when the pressure difference between gas pressure (P3) on the upstream side of the upstream-side shut-off valve (31) and gas pressure (P1) on the downstream side of the downstream-side shut-off valve (33) is greater than a reference value.
摘要翻译： 本发明涉及一种燃料电池系统，其中高压气体供应管连接到燃料电池的气体供应开口，气体压力调节阀安装在高压气体供应管的中间，以及 上游侧和下游侧截止阀分别设置在高压气体供给管内的气体压力调节阀的上游侧和下游侧。 通过打开上游侧截止阀然后打开下游侧截止阀来激活燃料电池系统。 在燃料电池系统中，存在以下问题：当上游侧截止阀打开时，下游侧截止阀在下游侧关闭阀的上游侧的状态下打开， 氢供给管上的截止阀不能充分加压，通过氢压力调节阀的节流部的高压气体导致供给管脉动，产生大的噪音。 本发明是为了解决上述问题，在燃料电池系统中，设有将下游侧截止阀33打开的时间相对于打开时间的预定时间延迟的控制装置 上游侧截止阀（31）的上游侧的气体压力（P 3）与下游侧的气压（P 1）之间的压力差与上游侧截止阀 下游侧截止阀（33）大于参考值。

摘要： A handheld work machine comprises a main body comprising a prime mover and a handle fixed to the main body and configured to be gripped by a user. The handle is formed by pipe material and at least one reinforcement member is disposed at a longitudinal portion of the handle that configures a part of the handle. The reinforcement member may be formed by pipe material and preferably disposed inside the handle. The longitudinal portion where the reinforcement member is disposed may preferably include a fixed portion of the handle that is fixed to the main body.

摘要： A handheld engine-driven cutter is provided with a disk blade and a four-stroke engine that drives the disk blade, a filter through which air provided to the four-stroke engine passes, a carburetor that mixes fuel and the air that passed through the filter, a casing that houses the filter and the carburetor, and a filter bracket intervened between the filter and the carburetor, which guides the air having passed the filter to the carburetor. An oil separator is formed integrally with the filter bracket that protrudes out toward the carburetor.

摘要： A handheld engine-driven cutter is provided with a disk blade and a four-stroke engine that drives the disk blade. By employing the four-stroke engine, exhaustion of unburned gas and fuel consumption can be reduced. The engine cutter is further provided with a filter through which air provided to the four-stroke engine passes, a carburetor that mixes fuel and the air that passed through the filter, and a casing that houses the filter and the carburetor. The filter and the carburetor are arranged to align on a straight line along a direction of flow of the air passing through the filter and the carburetor.
