Title: Shaft clamping member and manufacture thereof
Inventor: HORIMURA HIROYUKI
IPC: B21K1/14
Filed: 1993-09-01
Abstract: PURPOSE:To extend a service life over a long time by constituting the first and second half bodies out of light alloy, concurrently forging the bodies within a cavity having a shaft clamping member shape, and further constituting the mating faces of both bodies of an infinite number of projections and recesses having a coupling relationship with each other due to a material flow at a forging process for both faces. CONSTITUTION:A rod member 3 and a cap 6 are aluminum forged parts concurrently forged in a cavity having the shape of a connecting rod. Both mating faces 8 and 10 thereof opposite to each other are formed, using a material flow at a forging process, and have an infinite number of recesses a1 and a2, and projections b1 and b2 having a coupling relationship with each other. As a result, the dislocation of the faces 8 and 10 from a parallel direction is properly prevented with the recesses and projections a1 and a2, and b1 and b2. Also, as the recesses and projections a1 and a2, and b1 and b2 are formed due to a material flow, the array thereof becomes extremely irregular and has a micron size. Thus, stress generated between the faces 8 and 10 is properly dispersed and the durability of the irregularity coupling structure of the faces 8 and 10 can be improved.

Abstract: PURPOSE:To decrease the size of an electric discharge lamp lighting-device by applying a preheating current from a direct current source to one-side filament of an electric discharge lamp during the unlighted session of the lamp, and applying preheating-currents respectively to both side filaments of the electric discharge lamp so as to light the lamp at the time of lighting it. CONSTITUTION:Because each of transistors 5, 6 makes its switching operation during the unlighted session of an electric discharge lamp 1 and the operating frequency f1 hereof accordingly corresponds to the value of sq. rt. 1/2piLC, the operating frequency is determined on inductance in a transformer 7, each of resonance capacitors 13, 14 and the primary conversion capacity of each of preheating-current-limiting capacitors 10, 11 respectively. With a transistor 15 turned OFF a phototriac 16 is set in its OFF condition, and consequently a secondary voltage is not impressed on the electric discharge lamp 1 so that preheating-windings 8, 9 preheat filaments 3 of the electric discharge lamp 1 respectively via the preheating current-limiting capacitors 10, 11. When the transistor 15 is turned ON to turn on a relay 17 by decreasing the voltage of a lighting-signal terminal (a) to its low level at the time of lighting the lamp, the contact (b) of the relay is opened to disconnect the resonance capacitor 13 so that the operating frequency f2 of each of the transformers 5, 6 may be increased as compared with the frequency f1 according to the above-stated formula, sq. rt. 1/2piLC. The limiting impedance of a preheating current is thus decreased more than the value of 1/2piFC to increase the volume of the preheating current.

Abstract: PURPOSE:To ensure automated cooking such as sake heating, milk warming, and rice and subsidiary articles heating in cooking with one button by detecting foods or the width of a food container when a food placement table is rotated and heating the foods based upon a detection result. CONSTITUTION:A rotary mechanism 5 is driven to rotate a food placement table 4 by one revolution. At this time, an optical path from an LED 1a, 2a is projected onto the food placement table 4. For example, when food containers of 80mm diameter and 120mm diameter are placed at the center on the food placement table 4 and placed displaced from the center, the diameter of the food container 8 is estimated from the diameter of a fraction of the container shielded from light using a microcomputer 7 to discriminate the type of the food container 8. Further, when the optical path of a second light sensor is transparent at a reference position and at a location where the food placement table 4 is rotated 180 degree from the reference position, the diameter of the food container 8 is judged to be 100 mm or less. Thus, the type of the food is discriminated and based on a result of the discrimination heating control of the food is performed by the microcomputer 7.
