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 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.

Abstract: A method of manufacturing a hollow stabilizer includes a forming step of subjecting an element pipe to a bending process, to form a product shape including bent portions, and a quenching step of quenching the element pipe subjected to the bending process. In the quenching step, a cooling process is performed by immersing the element pipe made of steel in coolant and by spraying the coolant to an outer surface of the bent portion.

Abstract: A coil spring modeling apparatus includes a first attachment member disposed on a lower spring seat, a second attachment member disposed on an upper spring seat, an actuator unit formed of a Stewart-platform-type parallel mechanism, a spring height detection mechanism, and a controller. The spring height detection mechanism is constituted of displacement gauges such as a linear variable differential transformer. These gauges are provided on hydraulic cylinders, and detect amounts of displacement relative to the reference lengths of the hydraulic cylinders, respectively. A hydraulic pressure supply device is controlled by the controller and supplies fluid pressure according to the displacement detected by the gauges to the respective hydraulic cylinders.
