Title: Method and apparatus for die casting
Inventor: TAKEHISA FUMITAKA
IPC: B22D17/20
Filed: 1985-12-27
Abstract: PURPOSE:To prevent the blistering of a product by forming a high temp. part into a passage connecting a die space and injection sleeve, and blowing a lubricating agent thereto then injecting a molten metal into the die space. CONSTITUTION:A sprue core 20 is provided in the position of a moving die 12 where the die faces the injection sleeve 14. A lubricating oil injection passage is formed to ejector pins 22 near the same. The pins 22 are respectively connected via an air passage 24 and a lubricating agent passage 26 to a compressed air source and lubricating agent reservoir 28. The pins 22 are projected into the die space and the lubricating agent is injected to the sprue core 20 so that the oil-component of the lubricating agent is carbonized and stuck to the surface of the core 20 heated to a high temp. The molten metal is then injected from a sleeve 14 into the die space. Since the molten metal is poured by carbonizing the lubricating agent, the blistering of the product by the expansion of the lubricating agent is prevented.

Title: Manufacture of agglomerate
Inventor: SAKAMOTO NOBORU
IPC: C22B1/14
Filed: 1986-12-15
Abstract: PURPOSE:To reduce the cost of manufacture of agglomerates by reducing the amt. of quick lime added as a flux when agglomerates for a blast furnace are manufactured by adding a flux to fine iron ore, pelletizing them, coating the surfaces of the resulting green pellets with coke breeze and firing the coated pellets. CONSTITUTION:When quick time is used as a flux to be added to fine iron ore, quick lime produces a significant effect because it also acts as a binder, but the cost of quick lime is higher than that of slaked lime, limestone, dolomite, bentonite or water granulated blast furnace slag as other flux, so quick lime is added to fine iron ore by a reduced amt. of 1.0-2.5wt%. They are kneaded with water and pelletized, the surfaces of the resulting green pellets are coated with 2.5-4.0wt% coke breeze and the coated pellets are fired in a firing furnace provided with a travelling endless grate to manufacture agglomerates as starting material for a blast furnace. Since the amt. of quick lime used as a flux is small, the cost of manufacture of agglomerates can be reduced.

Title: Magnetic disk cartridge
Inventor: SUZUKI HIDEO
IPC: G11B23/02
Filed: 1993-11-30
Abstract: PURPOSE:To prevent the generation of an error at the time of recording and reproducing signals by providing this cartridge with a shutter which does not pick up incoming dust by electrification. CONSTITUTION:This magnetic disk cartridge 1 has a jacket 2 which houses a disk-shaped recording medium therein and has a head insertion hole 23. The shutter 5 slides the jacket surface to open and close the insertion hole 23. At least the surface of the shutter consists of a polymer alloy resin, of which the half-life of attenuation to electrification is <=10 seconds and the specific volume resistivity is 1X10<11> to 1X10<13>OMEGA.cm. The polymer alloy resin, such as polyacetal resin, polybutyrene terepthalate resin or polypropylene resin, has an excellent band attenuation characteristic, is suitable for working with high accuracy and is, therefore, preferably as the shutter material. The effect of preventing the pickup of the incoming dust is obtd. not by the antistatic agent added to the material but by the used shutter material and is, therefore, maintained over a long period of time. Since the dust is not attracted on the shutter surface, the dust does not infiltrate the inside of the jacket and the generation of the error is prevented at the time of disk operation.

Title: Method and device for transport and stacking of sheet material
Inventor: SHINOZUKA TOMOYUKI
IPC: B65H29/60
Filed: 1999-10-22
Abstract: PROBLEM TO BE SOLVED: To provide a method and device for transporting and stacking a sheet material capable of certainly preventing enlargement of any trouble in stacking and lessening the burden imposed on the operator. SOLUTION: A sheet material stacking device 34 is equipped with a sensor 44 to sense a PS plate 30 in the case of trouble in stacking. A changeover gate 52 and a conveyor 48 are installed between two conveyors 32A and 32B. When the sensor 44 senses PS plate 30, the gate 52 rotates so that the PS plate 30 is transported by the conveyor 48 to reach an accommodation box 50. Because there is no risk that any additional PS plate 30 is fed to the stacking device 34 or the sheet is pinched by a hold-down belt 58 and a conveyor 32, eventual trouble in stacking can be prevented from enlarging. Because there is no need for the operator to monitor the stacking device 34 as conventional, the operator can have a lessened burden.

Title: Glow plug control unit
Inventor: NOMURA MANABU
IPC: F02P19/02
Filed: 1992-10-12
Abstract: PURPOSE:To restrain a power MOSFET from being heated so as to prevent thermal breaking of products by providing a protective circuit which, when connected to a storage battery with inverted polarity, applies a voltage to a gate to which voltage of inverted polarity is applied to turn on the power MOSFET. CONSTITUTION:While connections to a storage battery 1 are normal, a power MOSFET driving signal output from a control circuit is converted into an appropriate voltage, which is then applied to a gate 3g so that power is applied to a power MOSFET 3. While connections to the storage battery 1 are inverted, a diode 4 is forwardly biased by the inverted-polarity storage battery 1 and power is applied thereto and a bias voltage is applied to the gate 3g to turn on the power MOSFET 3. Then voltage of the storage battery 1 is applied to the source and drain of the power MOSFET 3 via glow plugs 2a-2d and a current tends to flow through a parasite diode 3a; however, since the power MOSFET 3 is conducting at the same time by way of the diode 4, no current flows through the parasite diode 3a. Therefore, thermal breaking can be prevented.
