Abstract: The present invention provides a method of feeding an agent, capable of stabilizing a remaining agent of a feeding part in characteristic and amount just before definitively feeding an agent to each definitive portion. The method includes intermittently moving a feeding part to a plurality of definitive portions defined on a structural object to definitively feed a flowable agent with a predetermined amount to each one of the definitive portions. The structural object includes a semi-finished product part with the definitive portions and a frame to be separated from the semi-finished product part. The frame includes a waste portion for the flowable agent. The waste portion has a same form as the definitive portions. The feeding part wastefully feeds the flowable agent to the waste portion with a same amount as said predetermined amount and thereafter starts the intermittently moving for the definitively feeding of the flowable agent.

Abstract: A probe unit according to the present invention is suitable for allowing a large current to flow. In the probe unit that accommodates a plurality of contact probes for electrically connecting an inspection target object and a signal processing device used to output an inspection signal, both ends of a large current probe (3) are electrically connected to electrodes of a contact target object, and a large current is made to flow via a metal block (50) that comes into contact with both end portions of the large current probe (3).

Abstract: An accumulator according to an embodiment includes, for example, a base member; a cover member welded to the base member, the cover member and the base member defining a pressure chamber therebetween; a stretchable partition member that partitions the pressure chamber into an inner chamber and an outer chamber; and a labyrinth structure provided in at least one of a first part of the base member and a second part of the cover member. The first part is located closer to the outer chamber than a welded part between the base member and the cover member. The second part is located closer to the outer chamber than the welded part, facing the first part.

Abstract: A shift device for a boat includes a lever which can be operated about a predetermined axis, and a lever operation suppression mechanism which suppresses an operation of the lever. The lever operation suppression mechanism includes a load applying portions (a first load applying portion and a second load applying portion) which apply different loads to the lever in a first operation period of operating the lever between a neutral position of the lever and a first position corresponding to a forward movement of the boat, and in a second operation period of operating the lever between the neutral position and a second position corresponding to a backward movement of the boat.
