Title: Drive system for heat gas machine
Inventor: KAWAKITA TSUNEHIRO
IPC: F02G1/053
Filed: 1980-11-04
Abstract: PURPOSE: In a drive system for a heat gas machine where two crank shafts are arranged in parallel and coupled while interlocked, to prevent the single contact to a crank metal by providing a ball and roller bearing which is supported at the fixed side through a hydrualic damper on the end of the crank shaft.  
     CONSTITUTION: When a crank shaft 13 will approach to contact with a crank metal 15 during the operation of an engine, a roller bearing secured to the shaft 13 will move similarly. Since said bearing 29 is supported at the tip of a piston rod 30 of a hydraulic damper 28 the base end of which is supported on a cylinder block, the piston 29 in the damper 28 is pulled in the same direction thereby the oil 35 in the damper 29 will move through a small hole 29a in the piston 29 in the opposite direction of the piston 29. Since the oil will move slowly the shifting of the crank shaft 13 in the direction of single contact is prevented.

     CONSTITUTION: Mixed sand 30 is charged into the spacing formed by a pattern plate 1, flask 6 and build-up flask 7 and compressed air is supplied from air feed port 13 into a cover member 8 by opening a gate valve 16. The compressed air passes through the small-diameter holes 12, 12 of a squeeze plate 11, its outside circumference and the inside surface of the cover member 8, then flows through the inside of the mixed sand 30 in the build-up flask 7 and flask 6, subsequently passes through vent plugs 5, 5, small holes 4, 4, recess 23 and through-hole 24 and is exhausted to the atmosphere. As a result of this, the mixed sand 30 is packed to a high-density state. Thence, a cylinder 9 is operated to lower the squeeze plate 11 and compress and raise the mixed sand 30, after which the gate valve 20 is opened for the specified time to supply the heated low-pressure compressed air to the inside of the cover member 8 through exhaust port 13. The moisture in the mixed sand 30 is evaporated away and the sand particles are firmly bonded by water-soluble binders.

Abstract: PURPOSE:To protect an inverter from overcurrent by providing a protective circuit that operates if a first detector continues detecting the inverter output exceeding a first current level for over a given time or if a second detector detects the inverter output exceeding a second level current. CONSTITUTION:The output current of an inverter device 1 is detected by an inverter output current detector (AD) 7 and conduction time is counted by a conduction time counter 4 when an output current exceeding the first detection level set by a first level comparator 8b is detected. Then, when a specific allowable time is exceeded, H is output to an OR gate 5. Also, when a second detection level where the detection current value of the AD 7 is stored is exceeded by a second level comparator 9b, H is output to the OR gate 5. The first detection level is set greater than the second detection level, thus enabling an inverter control circuit 6 to protect the inverter device 1.
