Title: Gypsum investment casting method
Inventor: NAKADA MAMORU
IPC: B22C9/04
Filed: 1989-01-17
Abstract: PURPOSE:To obtain a casting having high quality by setting a pattern material having chiller-shape to the prescribed part in a wax pattern, pouring gypsum, taking out the pattern material after solidifying, removing the wax, burning the gypsum to make the gypsum mold, fitting a chiller into the recessed part taking out the pattern material and pouring molten metal into the gypsum mold. CONSTITUTION:The wax pattern 1 composing of a product part 1a and a runner part 1b is charged in an iron-made frame member 2 as turning the bottom part thereof upward. The pattern material 3 having the same shape as the chiller 7 is put on the part, where cooling speed is to quicken in the product part 1a. The gypsum 4 is flowed into spaces among the pattern material 3, wax pattern 1 and the frame member 2. In case the pattern material 3 is metal (alloy), the pattern material 3 is pulled out from the gypsum 4 and in case this is made of soluble resin, the pattern material 3 is left as it is. The whole is heated at about 700 deg.C and the wax pattern 1 is vaporized and removed and the gypsum 4 is burnt to make the gypsum mold 5. The mold 5 is turned upside down and the chiller 7 is inserted into the recessed part 6a at the bottom part and molten metal is poured into the cavity 6b. By this method, the cooling is quickened at the thick part and the shrinkage hole is prevented and the casting having high quality and high strength can be obtd.

IPC: H05B6/12
Filed: 1990-01-18
Abstract: PURPOSE:To keep the internal temperature of a pot uniform at all times, enhance an effect for water absorption into rice and obtain tastily cooked rice by making an induction coil spiral, applying a single layer winding to the inner side of the coil and so forming the outer side thereof as to have a plurality of winding layers for increasing the number of turns per pot area. CONSTITUTION:An induction coil 8 is constituted with a single element wire bundle wound spirally, and divided into an inner side portion for heating the central part of a pot 5 and an outer side portion for heating the peripheral part thereof. The inner side portion has a single layer winding 8a and the outer side portion is formed into a double layer winding 8b with two windings overlapped, thereby making the outer side portion of the oil 8 larger than the inner side portion in terms of the number of turns per area of the pot 5. When high frequency current is supplied to the induction coil 8 via a control board 11, lines of magnetic force are generated and eddy current is generated within the pot 5. In addition, the bottom of the pot 5 itself opposite to the induction coil 8 generates heat and a cooking material is thereby heated. In this case, heat generation at the bottom outer part of the pot 5 becomes higher than on the inner part, thereby actively facilitating the outer turn of water convection in the pot 5. According to the aforesaid construction, the cooking material in the pot 5 is subjected to the uniform and regular temperature rise of water, and it becomes possible to tastily boil rice without formation of a hard core and that in a uniform condition.

Title: Copying machine
Inventor: NAGASHIMA YOSHIYASU
IPC: G03G15/04
Filed: 1984-01-20
Abstract: PURPOSE:To alloy copying operation only when variable power rate is less than a specific value by stopping the operation of an optical system only when reduction magnification or enlargement magnification exceeds the specific value. CONSTITUTION:The calculated variable magnification of a copying machine is compared by a comparing circuit with previously inputted specific magnification which determined a normal use range, and information indicating whether the variable magnification is within the range of the specific magnification is outputted to a CPU. The CPU inhibits the copying operation even when a copy button is pressed unless the variable magnification is within the specific magnification range. In this case, the CPU attracts operator's attention through a display part provided to the copying machine. Consequently, the copying operation is permitted only when the variable power rate is only within the specific magnification range.
