Title: Starting decompressor for engine
Inventor: TERASHITA NOBUYUKI
IPC: F01L13/08
Filed: 1985-09-07
Abstract: PURPOSE:To simplify operation with obtaining the decompression action for a necessary time at the one time lever operation of a decompressor, by pivotably supporting a rocker arm with a hydraulic rush adjustor adjusting automatically the clearance of a tappet mechanism. CONSTITUTION:When the wire of a decompressor is stretched on starting of an engine, the lever 19 of the decompressor is pivotally moved to the position of a full line, so that a decompressor cam 20 presses down a rocker arm 9. Thereby, an exhaust valve 4 is lowered to the position of a full line so as to open against a valve spring 5. At the same time, a hydraulic rush adjustor body 12 also descends to the position of a full line. Then, after oil flows into a high pressure chamber 16 from a reservoir chamber 13 by the action of a check valve 15, this oil leaks through the gap between the adjustor body 12 and a plunger 14, so that the adjustor body 12 is raised gradually. Therefore, the decompressor action of a necessary time can be obtained at a one time operation.

IPC: B29C45/76
Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To prevent defects of a flow mark or the like from occurring due to discontinuity of a resin flow by a method wherein a resin amount to which a calculated cooling solidification shrink amount is added is filled into a cavity, and after an injection speed is reduced to a set value, mold clamp pressure and injection pressure are synchronously controlled. SOLUTION: By using a mold clamping mechanism wherein mold clamp force is loaded by pushing a movable board 20 to a fixed board side with a mold clamp cylinder 3, a cooling solidification shrink amount of resin is calculated. A resin amount to which the shrink amount is added is filled by injection into a mold cavity 28. Besides, a mold is preliminarily held at a specific mold open amount position to the mold clamping mechanism side. Then, after detecting that a detected signal of an injection speed detection part 6 is reduced in speed to a K value, a comparison control part 63 sends a mold clamp start signal to a mold clamp control part 66 via a synchronous control part 62, and besides starts a timer 64.  Thus, the synchronous control part 62 synchronously controls mold clamp pressure and injection pressure, and carries out injection press molding wherein injection is interlocked with mold clamping.

IPC: B02C1/00
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To stabilize crushing reaction by holding the pushing-in thrust of a breaker to a substance to be crushed at set pressure, interrupting an oil passage by the differential pressure of the primary-side pressure and secondary-side pressure of a push-in cylinder and obstructing the sudden change of the push-in movement of the breaker. SOLUTION: A breaker 40 is supplied with a hydraulic fluid and crushing thrust is given by a push-in cylinder 24, and pushing-in thrust supplies the head- side oil pressure chamber 44 of the cylinder 24 with oil pressure. Supply pressure to the cylinder 24 is adjusted at set pressure through a balancing valve 50 in the supply of oil pressure at that time, and works so as to give constant pushing-in thrust to the breaker 40. Consequently, the pushing-in reaction of the breaker 40 is received by crusher itself, and reaction is held constant and the stability of operation is ensured even when the crusher is loaded on a small- sized construction equipment.  When a differential-pressure driving valve 60 is disposed on the outlet side of a rod-side oil pressure chamber 56, a discharge oil passage 58 is interrupted at front-rear differential pressure and an object is punched by a chisel 42, the crusher is shut down automatically at the time of emergency. Accordingly, the safety of crushing operation can be improved.
