Title: Chucking device for gear-like work
Inventor: SEKIGUCHI SHINGO
IPC: B23Q16/02
Filed: 1991-02-08
Abstract: PURPOSE:To eliminate adjustment of detecting timing accompanying the positioning adjustment of an indexing pin during setup changing time by detecting the completion of indexing of a work, made by the indexing pin installed on a chucking device, with displacement of the indexing pin. CONSTITUTION:The position of an indexing pin 17 is adjusted by turning a detector shaft 18 with the shaft 18 pressed against a spiral stopper surface 36 of a pin stopper 33. Even if the detector shaft 18 is turned, the position of an air port 29 necessary for detecting the completion of indexing relative to that of an air groove 32 is not varied while the detector shaft 18 is pressed against the stopper surface 36 since the spiral air groove 32 is in parallel with the stopper surface 36. Thus the positioning of the indexing pin only is required for detecting completion of indexing.

Filed: 1992-02-03
Abstract: PURPOSE:To eliminate turbulence of control within a control stable range generated by ON-OFF of liquid injection in a freezer, in which pressure reducing degree of a main pressure reducing mechanism is regulated multi-stagedly so that outlet temperature of an evaporator can be constant. CONSTITUTION:A liquid pipe at a condenser outlet and an intake pipe of a compressor in a refrigerant circuit are connected by an injection bypass through an opening/closing valve and a main pressure reducing mechanism. A boundary value Tmd is set within a middle range Rmd between an injection range Rin on a higher side of outlet temperature of an evaporator and a wet and dangerous range Rsi on a lower side. When a set value Tws of the outlet temperature of the evaporator is over the boundary value Tbd, liquid injection is carried out constantly by an opening/closing control means above a lower limit Tdn of a stable range. To the contrary, when the set value Tws is under the boundary value Tbd, the liquid injection is carried out only above an upper limit Tup of the stable range. By this, ON/OFF of the liquid injection within the stable range is eliminated.
