Title: Ceramic heater
Inventor: SOMA TAKAO
IPC: H05B3/00
Filed: 1990-07-05
Abstract: PURPOSE:To obtain a ceramic heater with high-precision temperature control by providing a heater main body buried with a resistor mainly made of tungsten or molybdenum in a ceramic substrate. CONSTITUTION:A resistor 4 mainly made of tungsten or molybdenum with a simple and large change of resistivity by temperature is buried in a dense ceramic substrate 3 to form a heater main body 1, and a power feed device 2 performs power control based on the change of the resistance value by the temperature of the resistor 4 as the control information. The temperature change of the resistor 4 is immediately detected with no time lag to control the feed power, and the response to disturbances is made very quick. The occurrence of cracks on the buried junction section of a thermocouple and the instability of heat transfer are prevented, and the temperature of the resistor 4 itself can be correctly detected and controlled.

Title: Smelting method for high-cleanliness steel having low oxygen concentration
Inventor: KATO YOSHIHIDE
IPC: C21C7/06
Filed: 1991-07-18
Abstract: PURPOSE:To smelt the high-cleanliness steel having a low oxygen concn. CONSTITUTION:The bottom end of an iron container 6 packed with a synthetic flux 4 for absorbing the resulted product of deoxidation is immersed between the molten steel 3 in a ladle 10 and molten slag 5 flowing out of a converter in the process of tapping and the container 6 is dissolved to add the synthetic flux 4 at the time of tapping the molten steel 3 subjected to refining in the converter to the ladle 10 and subjecting the molten steel to a deoxidation treatment. Since the molten layer of the synthetic flux 4 is formed between the molten steel 3 and the molten slag 5, the resulted product of the deoxidation flocculated and floated in the molten steel 3 is efficiently absorbed in the synthetic flux 4 and the reoxidation of the molten steel component by the molten slag 5 is prevented.

Filed: 1987-07-16
Abstract: PURPOSE:To obtain a fin tube having high joining strength and thermal conductivity by pulling up solidified part near molten metal surface on surface of a tube composing of material having higher melting point than that of this molten metal dipped in the molten metal together with the tube in order at the prescribed interval. CONSTITUTION:After dipping the tube 2 into the molten metal 1 as remaining the upper end part having length B, cooling blast (for example, inert gas) is blown on the molten metal surface 15 from cooling nozzle 16. By this method, the molten metal surface 15 and neighborhood of the surface of the molten metal 11 are cooled to less than the melting point thereof in the range of depth W to form thin solidified layer 3a. The tube 2 is pulled upward by the distance corresponding to the prescribed fin pitch A and shifted upward under fixing condition of the solidified layer 3a to the tube 2 to part from the molten metal 11. By this method, one piece of the fin 3 is formed around the tube 2. Successively, by the same work as the above, the tube 2 is pulled up by the distance A, and a second fin 3 is formed. After that, by repeating the same work, the prescribed number of fins 3 is formed around the tube 2.

Title: Stereoscopic animation system
Inventor: WATANABE NORIO
IPC: G09F13/32
Filed: 1987-07-16
Abstract: PURPOSE: To project a stereoscopic screen as a moving picture by forming a 1st transparent printed matter and a 2nd transparent printed matter which has some patterns cut and other patterns equalized and arranging a polarizing spinner plate and a polarizing remaining pattern plate between a light source and the superposition body of 1st and 2nd printed matters.

The 2nd printed matter is obtained by transfer similarly to the 1st printed matter and has part of the pattern of the 1st transparent printed matter missed. Then the 1st and 2nd printed matters are put one over the other to match the patterns against each other. Then the rotary polarizing spinner plate B1 and a fixed polarizing pattern plate B2 are interposed between the light source and the reverse surface of the 2nd printed matter in the order and polarized light which sequentially projects the pattern of the 1st printed matter while dividing it linearly or from the center to the outer periphery is projected on the 1st and 2nd printed matters. Consequently, the stereoscopic picture can be projected as a moving picture.

IPC: G11C8/00
Filed: 1994-07-29
Abstract: PURPOSE:To realize excellent performance to price and to increase the read speed by simultaneously latching data by latch circuits in all blocks. CONSTITUTION:A ROM where instructions are stored is divided into ROMs 100 to 103, and in each block, data corresponding to addresses 4N, 4N+1,...4N+3 (N is not negative and an integer) are stored in ROMs 100 to 103 respectively. An address decoder 7 expands the address subjected to required translation in an address translation circuit 5 to actually access the memory cells of ROMs 100 and 101. Meanwhile, output data of moss 100 to 103 are latched by data latches 200 to 203. Data buffers 300 and 303 are opened/closed by gate signals 400 to 403 outputted from a data selector 11. Consequently, data in addresses 4N, 4N+1,...4N+3 are certainly read out at each time of one latch operation when the read start address is 4N or 4N+1.

Abstract: PURPOSE:To attain the high speed data transmission without the fluctuation of zero point, by providing a driver outputting a peak value through the change in low and high values in response to a long and a short signal, and reducing to zero the integration value of the signal for an arbitrary period. CONSTITUTION:A modulation circuit 4 consists of the 1st FF41 and the 2nd FF42 receiving transmission data from an input terminal 3 to a clear terminal.
