To provide an endoscopic surgical instrument, which enables to perform ligation in a body without pulling out a suture thread outside the body every time in an endoscopic surgery and to perform the operation safely and easily, and further, a user can easily learn how to use the endoscopic surgical instrument. Therefore, in the endoscopic surgical instrument having a needle holding part configured by a movable jaw and a fixed jaw at a front end of a tubular shaft that is an insertion part into an abdominal cavity, the movable jaw is disposed so as to be capable of rotating around the fixed jaw through a pivot shaft due to the remote control; the opposite side across the pivot shaft of the movable jaw is formed as a thread locking part; when the movable jaw is opened, the thread locking part slightly protrudes outside a tubular shaft; and when the movable jaw is closed, the thread locking part is prevented from protruding outside the tubular shaft.

To increase the force to draw the armature of an electromagnetic valve gear for driving a valve for opening or closing a high-pressure liquid passage and to alleviate valve bouncing, the surface of the core with a coil embedded therein is shaped flat and the surface of the armature facing to the surface of the core is shaped convexly spherical, or the surface of the core is shaped convexly spherical and the surface of the armature is concavely spherical such that the curvature radius of the concavely spherical surface is larger than that of the convexly spherical surface, or the armature is composed by piling thin plates of different diameters such that the surface of the armature facing to the surface of the core forms an approximate convexly spherical surface, so that the gap between the surfaces of core and armature is smaller in the central part compared to that in the peripheral part of the surfaces. By this, the interference of the surfaces is prevented with smaller initial gap in the central portion of the faces even when the armature is installed aslant caused by insufficient accuracy of the component parts, and strong electromagnetic attraction can be secured because the smaller the gap is, the stronger the electromagnetic attraction is.

An integrated air intake system may include an integrated body formed by combining a cylinder head cover at the top of an engine with an air cleaner body at a side of the cylinder head cover, an air duct connected to a side of the air cleaner body to make a channel for air sucked from the outside into the air cleaner body, an upper cover combined in contact with the air cleaner body at the top thereof, an intake hose connected to a side of the upper cover to supply purified air to an engine intake port, and an intake filter disposed in a space formed in the air cleaner body and the upper cover to purify the air sucked from the outside.

A semiconductor module has metallic radiator plates provided at central regions of principal surfaces of a sealing resin so as to expose from these principal surfaces. The metallic radiator plates and the principal surfaces of the sealing resin are bonded via grease gaps to heat receiving members. The grease gaps are widened in outer regions far from the metallic radiator plates compared with inner regions adjacent to the metallic radiator plates, to prevent external air from entering into the grease gaps even when the semiconductor module causes repetitive thermal expansions and contractions.

A wig is fabricated by: a masking sheet, having a great number of openings around 10 mm in diameter formed therein, being applied to a side of a wig base which is to face the scalp of a wearer; a silicone adhesive agent being applied to the wig base through the openings; one end of a tablet formed of a silicone substance, which can be placed within the opening, being adhered to the silicone adhesive agent, and further, a silicone adhesive agent being applied to a surface of the tablet and dried; following which the masking sheet is removed, thereby providing silicone protrusions fixed to the side of the wig base which is to face the scalp of the wearer.
