Title: Method for heat-drying ladle
Inventor: MATSUDA KIYOSHI
IPC: B22D41/02
Filed: 1991-08-06
Abstract: PURPOSE:To reduce lowering of molten steel temp. and to prevent dissolution of hydrogen into the molten steel at the time of receiving the steel by making an iron shell at bottom part of a ladle double structure, arranging a combustion gas venting hole in the iron shell contacting with refractory and sucking the burner combustion gas. CONSTITUTION:By burning methane series hydrocarbon with the burner 7, the temp. in the ladle is raised and on the other hand, gas in the double structural iron shells 4 is sucked under reducing pressure from a suction hole 6 with a vacuum pump. By sucking the gas under reducing pressure from the suction hole 6, the burner combustion gas G in a ladle is passed through the brick and joints and discharged to outer part from the combustion gas venting hole 5 through the suction hole 6. In this way, drying and heating to the brick in the ladle bottom part are promoted and unevenness of raised temp. distribution on the brick in the ladle is reduced. Further, by sucking the gas under reducing pressure from the suction hole 6 even at the time of refining in out of the furnace, steam generated from insufficient dried mortar is discharged to the outer part and the dissolution of hydrogen into the molten steel can be prevented.

Title: Production of insulating capsule toner
Inventor: KAKIMI FUJIO
IPC: B01J13/20
Filed: 1983-10-20
Abstract: PURPOSE:To obtain an insulating capsule toner having high electrical resistance by removing the ion material sticking to the surface of the capsule toner in the stage for manufacturing the capsule toner used for electrophotography. CONSTITUTION:The microcapsule formed in an aq. liquid is separated in the form of a slurry material by a method such as centrifugal sepn. and the slurry is dispersed in demineralized water or distilled water, by which the slurry is preliminarily cleaned. The microcapsule is separated from the cleaning water. The slurry is dispersed in water contg. an ion exchange resin to clean the microcapsule. The cleaning is preferably accomplished in a way as to remove both anion and cation sticking to the microscapsule and therefore combination use of the cation exchange resin and anion exchange resin is preferable. The dried capsule toner exhibits high electrical resistance as ionic impurities in particular are less stuck thereto and therefore the capsule toner has an excellent characteristics for electrophotography for which triboelectrification is used.

Title: Fixing device and image forming device
Inventor: UENO SUEO
IPC: G03G15/20
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To inhibit a rush current to a heating element and to prevent adverse effect exerted on the life of the heating element by supplying AC voltage to the heating element so that the current having a frequency component may flow, and making the heating element have a given resistance value to the current of the high frequency component generated just after the supply of the voltage, whereby a current quantity to the heating element is controlled. SOLUTION: When a semiconductor switch SSR is turned on just after power is supplied and power source voltage from an AC power source 140 is applied, the transition waveform of the current when the current rushes in rises steeply and has the frequency component ten times as high as the ordinary one. Therefore, the impedance of a transformer 142 is made ten times as high as that at the normal time and the rush current to a heater lamp 131 being a heat source for fixing is restrained to about 1/10. Once the resistance value of the lamp 131 has been gradually increased with the temperature rise of the lamp 131, the frequency component of the current is gradually changed to a normal value, and the impedance of the transformer 142 to the frequency component of the current is gradually decreased, then the current flowing to the lamp 131 becomes a fixed current value.

Filed: 1991-08-07
Abstract: PURPOSE:To make it possible to form a wiring whose aspect ratio is increased by preliminarily forming a column-shaped metallic layer at a position where a contact hole or a through hole is formed. CONSTITUTION:A silicon substrate 1 is dipped in a gold plating solution where electric current is passed from the back of the substrate 1, which forms a gold plug 6 in an opening section 14 and eliminates a photoresist film 5. Then, after a BPSG film 7 is formed on the whole surface based on a CVD process, a photoresist film is applied thereto. It is etched-back under the condition that the etching rate of the BPSG film 7 is identical to that of the photoresist film where the surface of the gold plug 6 is exposed. Then, after an Si-contained aluminum film is formed based on a sputtering process, anisotropic etching-based patterning is carried out so as to form an aluminum wiring 8 connected with the gold plug 6. This construction improves the coverage of the aluminum wiring 8.

Title: Semiconductor memory
Inventor: NAKAJIMA HIDEHARU
IPC: H01L27/10
Filed: 1991-07-12
Abstract: PURPOSE:To increase a signal level and maintain sufficient noise resistance even when an accumulated capacity is decreased by reduction in a stacked capacitor area by increasing a differential potential between an upper electrode and a lower electrode of a stacked capacitor of a memory cell during data writing. CONSTITUTION:The potential of an upper electrode 11 for a row of stacked capacitors to which a stacked capacitor of a memory cell belongs, is set as -Vcc for example. Write voltage, say, Vcc is applied to a bit line BL. I this case, the differential potential between the upper electrode 11 and the lower electrode 9 during write time is 2Vcc. More specifically, the potential of the upper electrode 11 of the stacked capacitor of a memory cell to write during data writing is lowered to a minus(-) side, which increased the differential voltage between the upper electrode 11 and the lower electrode 9. This construction makes it possible to increase a write signal level and obtain favorable noise resistance even when the accumulated capacity is decreased by the reduction in a stacked capacity area.

Abstract: PURPOSE:To set optimum transfer density even if ambient temperature varies by forming a through hole in a lens barrel and exposing a sensor means and a thermistor to the same atmosphere. CONSTITUTION:When a document is copied, the density of the document 1 is judged first by EE scanning, an exposure lamp 2 is moved along the document 1, and lights reflected at plural measurement points on the document 1 are photodetected by the sensor 4 and photoelectrically converted. The obtained EE signal obtained at this time is converted by an I/V converting circuit 21 into a specific voltage, and the sensor 4 and voltage converting circuit input the output signal of the sensor 4 to an amplifier. In this case, a resistor and a thermistor TH are properly selected to set such composite resistance that the voltage is invariably constant even if the output current of the sensor 4 varies with the temperature. Then, the through hole is bored in the lens barrel in which the sensor 4 is stored, and consequently the thermistor TH outside the lens barrel and the sensor 4 are exposed to the same temperature at all times.

Title: Method for producing crystalline silicon carbide film
Inventor: UEHARA HIROSHI
IPC: H01L21/205
Filed: 1981-12-09
Abstract: PURPOSE:To make it possible to form a crystalline SiC film at a low substrate temperature, by forming a nucleus for the growth of SiC crystal on the substrate in advance to the formation of the SiC film. CONSTITUTION:An element such as Si is deposited on a substrate by an evaporation of sputtering to such a thickness as not to form a continuous film, e.g. 10- several tens of Angstrom , thereby to form a nucleus for the growth of SiC crystal. Subsequently, an SiC film is formed on the substrate by sputtering within a discharge gas containing methane as the reaction gas and using Si as the target, while maintaining the substrate within a predetermined temperature range of, for example, between 400 and 500 deg.C. According to this method, it is possible to lower the substrate temperature, so that the crystalline SiC film can be formed even on a substrate which cannot be heated to high temperature, such as glazed ceramic substrate.
