Title: Jig pallet device
Inventor: HORINO KAZUHIRO
IPC: B23Q7/00
Filed: 1985-01-22
Abstract: PURPOSE:To enable feeding of parts having low positional accuracy to a robot or an automatic by providing a mechanism for moving a jig pallet with small force in a face perpendicular against the take-out direction of work in pallet base thereby providing centripetal function to the pallet itself. CONSTITUTION:Upon supply of air from an air-compressor through an air supply port 6 provided below the pallet base 4, the air will pass through an air hole 5 of the pallet base 4, to float a jig pallet 3 on the pallet base 4. Consequently, the jig pallet can be moved with small force in moving direction of pallet. Upon lowering of robot band 1 under this condition to grip one work 2, the jig pallet mounting the work will slide in automatic centripetal direction 7 to move the work along the innerface of the robot hand. Consequently, centripetal motion of jig pallet 3 is performed automatically through sliding of the jig pallet 3 to enable feeding even of such part as has low positional accuracy to a robot or an automatic machine.

Title: Overspeed preventive device of internal-combustion engine
Inventor: KOMURASAKI SATORU
IPC: F02D17/04
Filed: 1982-01-21
Abstract: PURPOSE:To limit the speed of an engine at high temperature to a low speed and more properly protect the engine, by changing an overspeed preventive setting speed through temperature and decreasing the operating speed at high temperature time. CONSTITUTION:At normal revolution, an ignition signal of an ignition signal generator 1 is converted to an ignition pulse of adequate circuit closing rate by an ignition pulse circuit 2 to interrupt a conduction current of an ignition coil 5 via a switching circuit 3. Now if speed of an engine is increased to at least a preset value, a speed detector 6 outputs a speed detection signal and an ignition stop circuit 7 outputs an ignition stop signal synchronously with the ignition signal accordingly a bypass circuit 8 is operated to connect an ignition pulse input to the circuit 3 to the earth. In this way, overspeed can be prevented, however, a setting speed of the detector 6 is decreased by an output of a temperature detector 9 at high temperature, and an engine can be more properly protected.

Title: Low si operation method for blast furnace
Inventor: JINBO TAKAO
IPC: C21B5/02
Filed: 1987-01-16
Abstract: PURPOSE:To effectively recover Mn contained in slag in an iron making process consisting of blast furnace-desiliconization treatment equipment by increasing the content of Mn in blast furnace pig to desiliconize the molten iron and blowing powder of high Mn-content slag generated at the time of the desiliconization treatment into the furnace from tuyeres. CONSTITUTION:Mn ore is compounded with the raw materials charged into the blast furnace and the Mn oxide in the ore is reduced and is incorporated as Mn in the molten iron. An increase in the activity coefft. of Si in the molten iron is caused from such enrichment of the Mn content in the molten iron, by which the Si content in the molten iron is decreased and Mn is migrated as MnO into the slag. More specifically, Si in the molten iron is oxidized to SiO2 by MnO in the Mn ore and is thereby decreased. Mn formed at this time is oxidized to MnO by FeO in the slag. The MnO-contg. slag is pulverized and is blown together with pulverized coal from the tuyeres into the furnace, by which MnO is reduced to Mn and is recovered and incorporated into the molten iron.
