Title: Continuous casting method for strip
Inventor: SHIRAI YOSHIHISA
IPC: B22D11/06
Filed: 1988-07-29
Abstract: PURPOSE:To stably cast a strip having good shape having edge faces by arranging while fixing heat insulating refractories at side faces and edge faces of water cooling roll, respectively and rotating it while synchronizing these heat insulating refractories with the water cooling roll. CONSTITUTION:The water cooling roll 1 builds a water cooling construction in an inner part and is formed with copper, steel, etc., and solidified shell 4 is formed on the surface. The solidified shell is formed by rolling with rolling- reduction roll 5 having the same width, and carried. The heat insulating material 3' is composed of SiO2, etc., to be fixed by covering the side faces and edge faces of the water cooling roll 1. Consequently, the corner parts of the water cooling roll 1, which is insufficiently cooled, are not brought into contact with molten metal 2 and not thermally deformed. Further, since there is no gap between the water cooling roll and the heat insulating refractory 3, the solidified shell (penetration of the molten metal) is not developed in there and the sound solidified shell 4 is developed. In such a manner, the strip having good shape can be obtd. and since there is no penetration 4' of the molten metal, the heat insulating refractory 3' is not damaged and the stable operation can be executed.

Title: Plunger molten metal supplying vacuum die casting device and reduced pressure smelting vacuum die casting device
Inventor: UMEMURA AKIYOSHI
IPC: B22D17/14
Filed: 1988-07-29
Abstract: PURPOSE:To reduce gas defect and to improve the quality by connecting a molten metal supplying tube with a plunger sleeve at back side from the waiting position of a plunger tip at the time of reducing the pressure in a device for supplying the molten metal under reducing pressure in a cavity in a die and supplying the molten metal. CONSTITUTION:The plunger tip 4 is stopped at a front position from the molten metal supplying tube 5 and communicated with a vacuum tank 6 and the pressures in the cavity 2 in the die 1 and in the plunger sleeve 3 are reduced. At the time of shifting the tip 4 to the back side from the molten metal supplying tube 5, by difference between the pressure in the sleeve 3 and the atmospheric air pressure, the molten metal is sucked from a melting furnace 8 to supply the molten metal into the sleeve 3. Control of the molten metal quantity is executed by changing stopping time of the tip 4. At the time of supplying the desired quantity of the molten metal, the plunger 4 is pushed and the molten metal is injected, to obtain a product. The outlet of the molten metal supplying tube 5 becomes the atmospheric air pressure and the molten metal is returned back to the melting furnace 8. In such a manner, the supply of the molten metal is facilitated and the gas defect in the product can be reduced.

Abstract: PURPOSE:To form an appearance resembling a natural fruit on the surface of a container and to attempt to improve beauty and high class feeling of the container, by drawing a plastic sheet on which two or more colors are printed in such a way that color tone differences exist. CONSTITUTION:A plastic sheet 2, on which a printing wherein a color scheme is prepared in two or more colors so as to give color tone differences between them is applied in such a way that a fruit-like appearance is exhibited, is drawn to mold a cup-shape by means of a draw-molding machine. The printed part of the plastic sheet 2 is drawn by drawing and a change in the color tone is exhibited in accordance with the draw ratio. Especially, the color tone part 2c changes stepwisely and a natural gradation-like color tone is formed. Therefore, an appearance resembling a natural fruit is formed on the surface of a fruit-like container 1 and beauty and high class feeling are expressed. The draw ratio at draw-molding is represented by (the depth of the container)/(the diameter of the opening of the container) and the color tone difference shown on the appearance of the fruit-like container is influenced by this draw ratio and in general, the value of the draw ratio is preferably 0.1-2.0.

Title: Voltage ratio detecting circuit
Inventor: KOBAYASHI DAISUKE
IPC: H03K7/08
Filed: 1999-07-06
Abstract: PROBLEM TO BE SOLVED: To improve the output pulse width control speed and precision of a PWM circuit by logarithmically converting reference voltage and input voltage so as to output a voltage ratio signal corresponding to a difference between the output of a reference voltage logarithmic conversion circuit and that of an input voltage logarithmic conversion circuit. SOLUTION: Reference voltage V1 and input voltage V2 are in the range of the supplying voltage of amplifiers AMP1 and AMP2. The potential of the voltage ratio signal output node OUT of a voltage ratio detecting circuit becomes VB=Vin×V2/(V1+V2) to obtain a voltage ratio signal representing the ratio of the voltage V2 with respect to voltage V1 + voltage V2.  Upon inputting this voltage ratio signal VB=Vin×V2/(V1+V2) to the pulse generation circuit of the PWM circuit, the comparator of a pulse generation circuit compares the potential of the voltage ratio signal with the potential of the triangle wave signal of a prescribed period to output a signal which has high- level potential in a period when the potential of the voltage ratio signal is higher than that of the triangle wave signal and has low-level potential in a period when the potential of the voltage ratio signal is lower.

Abstract: PURPOSE:To house smoothly a bottle in a packing bag and to obtain a packed bottle the packed state of which does not change after housing by a method in which a bottle housing is carried out smoothly by using a flapper, a heat contraction of bag film is preliminarily carried out by heating only a periphery of an opening of a bag, and a bottle fixed by the bag film in the vicinity of the opening is heated. CONSTITUTION:At the same pace as a packing bag engages with a flapper 14, an insertion rod is made to extend so that a bottle 22 is inserted together with the rod into an insertion port formed by the flapper 14 and a guide 15. The insertion rod releases an opening of the bag 1 from the flapper 14 just before a head of the bottle reaches a closed part of the bag. At this time, hot air is jetted from a plurality of hot air nozzles 26, while rotating the insertion rod, so that the vicinity of the opening of the packing bag is heated, by which a periphery of the opening is partially heat contracted. When this partial heat contraction is finished, vacuum of a large-sized vacuum pad 23 is released. Then a packing bag attached bottle is made to drop down on a conveyor 27 and transferred to a shrink tunnel, where the bottle undergoes a whole heat contraction.
