Title: Production of work roll for cold rolling mill
Inventor: KIKUHARA TAKASHI
IPC: C21D8/00
Filed: 1986-07-04
Abstract: PURPOSE:To produce a work roll for a cold rolling mill having excellent wear resistance by forging a high-carbon high alloy cold working tool steel to a roll shape, then subjecting the steel to hardening by heating the same to the temp. of an austenite state then to cooling and hardening the same in multiple stages and tempering the hardened steel at a low temp. CONSTITUTION:The high-carbon high alloy tool steel for a cold working die is forged to the roll shape. The roll 1 obtd. in such a manner is subjected to progressive induction heating in an arrow direction by an induction heating furnace 2 provided with a heating coil 3 and is thereby heated to the temp. of the austenite state. The roll 1 is thereafter subjected to the hardening by changing the cooling rate to >=3 stages by a water spray cooler 4 having a draining plate 5 provided with a seal, a spray color 6 having a draining plate provided with a seal, a cooler 7 having a cooling pipe 8 to allow the flow of compressed air therein, etc. The roll is then subjected preferably to a sub-zero treatment to decompose the residual austenite to martensite. Such roll is subjected to the tempering treatment at <=200 deg.C to temper the surface layer and to provide toughness to the martensite. The work roll for the cold rolling mill having excellent wear resistance is thus obtd.

Abstract: PURPOSE:To sort recording materials after image formation in different modes according to the modes by controlling a stacking means on the basis of data stored in a memory means. CONSTITUTION:An elevator 210 is lifted up previously and all shelves 202 are mounted on the upper side of a cam 108. When copy paper is ejected from a main body and detected by paper detectors 106 and 107, the elevator is lowered by one stage and the lowermost shelf falls from the cam to stack the copy paper on the shelf. When the next copy paper is detected, the elevator is further lowered to stack the copy paper. When one group is copied completely, a solenoid 105 operates to free the cam 108, and the elevator 210 is lifted up. This operation is repeated until the quantity SET stored in a RAM, then the copying operation is all stopped. For example, when A4, 5, CHANGE, SET, ENT, 10, SET, and ENT are inputted with keys, five groups of ten sheets are copied.

Title: Hybrid integrated circuit
Inventor: HIDA HIROYUKI
IPC: H05K1/16
Filed: 1992-06-16
Abstract: PURPOSE:To simplify and assuring a functional trimming in a hybrid integrated circuit and to enhance a density of surface mounting by mixing a plurality of shapes, sizes of a functional trimming resistor components to be placed on the circuit. CONSTITUTION:A functional trimming resistor component 2 uses smaller shape and size than those of a functional trimming resistor component 1, and an initial set value 11 is so set as to become a value out of a target value. An electric signal is applied to a terminal 4, and a functional trimming is so conducted as to approach a target value while observing an output 9. Since the value 11 is so set as to be the value out of the target value, the component 1 is mostly finished only by regulating. On the other hand, even if it does not reach the target value if the component 2 is not trimmed, a regulating margin of the component 2 may be small, and a resistance value variable amount may be sufficient to be small. Therefore, a functional regulation can be simplified.

IPC: H01H33/59
Filed: 1991-06-27
Abstract: PURPOSE:To provide a pole mounted switch of a small size at a reduced cost. CONSTITUTION:On a cable way between a terminal 10 on a power source side and a terminal on a load side, a disconnector 2 and a PTC resistance element 3 are insertingly connected in series, respectively. A short-circuit switch 4 is connected to the cable way in parallel to the PTC resistance element 3, thus constituting a pole mounted switch 1. In shutting the cable way, the short-circuit switch 4 is opened by an electromagnetic drive circuit incorporating a timer therein prior to the opening of the disconnector 2. Meanwhile, in connecting on the cable way, the short-circuit switch 4 is closed after the closure of the disconnector 2 so that a current flowing in the cable way can be rapidly reduced by the PTC resistance element 3 immediately before the opening of the disconnector 2 and immediately after the closure thereof. Since a load exerted on the disconnector 2 can be remarkably reduced, the disconnector 2 and other parts items can be miniaturized at a reduced cost.

Abstract: PURPOSE:To give arbitrary ductility to film by making a rotation proportional flow valve function by tension of the film on an object to be packaged, making a hydraulic motor operate, and making the rotation peripheral speed of a secondary roller larger than that of a primary roller. CONSTITUTION:One end of film (a), which is held on a roll out shaft 7, is pulled out, the film (a) is passed in order around a primary roller 1 and a secondary roller 2, and wound around an object to be packaged (b) on a turn table 8. When the film (a) is pulled by tension due to the rotation of the turn table 8, a coupling 9 in a rota tion proportional flow valve 3 function; oil in an external hydraulic circuit 11, in which a hydraulic pump 10 is built-in is taken into the rotation proportional flow valve 3 by an amount witch is proportional to the number of rotations. The oil is sent out of a G rotor 12 to a closed circuit 5. When a uniform amount of oil is sent out to the closed circuit 5, a hydraulic motor 4 rotates, and the secondary roller 2 also rotates. For example, if the rotor of the hydraulic motor 4 is set to rotate twice as much as the rotor of the G rotor, the secondary roller 2 always rotates twice as much as the primary roller 1; and the film (a) is elongated by the differential in the number of the rotations. When a valve 6 is opened, the rotation speeds of both hydrau lic motors become uniform, and the number of rotation speeds of both rollers become uniform also.
