Title: Prolonging method for life of refractory of ladle
Inventor: HIMENO TADASHI
IPC: B22D41/05
Filed: 1981-11-25
Abstract: PURPOSE:To prolong the life of refractories in the bottom part of a ladle and to reduce the costs of refractories considerably by charging beforehand molten slag into the bottom part of the ladle and allowing the same to solidify. CONSTITUTION:Molten slag 5a after refining by decarburization reduction in an AOD furnace 4 is charged into a charging ladle 3. The ladle 3 is kept standing by in order to receive the molten steel 2 of an electric furnace 1. During this time, the slag 5a charged into the ladle 3 cools to solidify to solidified slab 5b which protects the bottom part of the ladle. When the molten steel 2 of the furnace 1 is received by using the ladle 3, charging flow (b) contacts directly with the solidified slag 5b; therefore, the refractories in the bottom part are protected against the heavy impact in an initial period. On the other hand, the slag 5b is melted gradually by the charging flow (b) of the molten steel but at around the time when the bottom part of the ladle exposes, the molten steel accumulates sufficiently in the ladle and the impact of the flow (b) is relieved.

Title: Device for producing thin metal film
Inventor: ANDO TOMOAKI
IPC: C23C14/20
Filed: 1987-07-29
Abstract: PURPOSE:To stably travel a substrate and to prevent the thermal deformation and thermal decomposition of the substrate by making the potential difference between the metallic subbing layer on the substrate of a plastic material traveling along the periphery of a cylindrical can and the cylindrical can lower than that at a vapor deposition part on the input and output sides. CONSTITUTION:The tape-shaped substrate 1 of a plastic material provided with the metal substrate layer is traveled along the periphery of the cylindrical can 2. The vapor of a metal atom from a vaporization source 5 is vacuum-deposited on the substrate 1 at the vapor deposition part under the cylindrical can 2 to form a thin metal film on the metallic subbing layer. In this case, a potential difference is imparted between the metallic subbing layer and the can 2 by an electric power source 12 and a grounded metallic nip roller 11 to firmly attach the substrate 1 to the periphery of the can 2, and the thermal deformation and thermal decomposition of the substrate 1 are prevented. Furthermore, electric power sources 10 and 15 are connected to the metallic subbing layer on the input and output sides of the cylindrical can 2 through free rollers 9 and 14. As a result, the potential difference between the metallic subbing layer and the can 2 on the input and output sides is made lower than that at the vapor deposition part. By this method, the traveling of the substrate 1 is stabilized, and a high-quality thin metal film is obtained.

Title: Engine-driven type air conditioner
Inventor: NAKAMURA MASAHIKO
IPC: F25B27/02
Filed: 1988-07-30
Abstract: PURPOSE:To protect a muffler from being corroded by condensed water produced from exhaust gas by providing the silencer for absorbing noises of the exhaust gas between an engine and an exhaust gas heat exchanger. CONSTITUTION:When an engine 1 is driven, exhaust gas is released into an exhaust gas pipe 6. The exhaust gas passes through a muffler 3 as it is held at high temperature. The exhaust gas whose noise level is lowered is fed in an exhaust gas heat exchanger 2 and the heat of the exhaust gas is recovered. When the temperature of the exhaust gas which passes through the muffler 3 is high, condensed water from the exhaust gas is not produced and the inner wall of the muffler 3 is not corroded by the condensed water. Further the condensed water produced in the exhaust gas heat exchanger 2 is drained from a drain exhaust port 5. Thus, since the condensed water is not produced from the exhaust gas in the muffler 3, the muffler 3 is completely protected from being corroded by the condensed water.

Title: Electrodeless discharge lamp lighting unit
Inventor: SHIMIZU KEIICHI
IPC: H05B41/24
Filed: 1993-07-30
Abstract: PURPOSE:To reduce higher harmonic current components transmitted to the side of an exciting coil without increasing circuit loss and make a high frequency generation source hard to cause ringing. CONSTITUTION:Since the series circuit composed of a coil L1 and a capacitor CS is capacitive with the basic frequency omega0 of a high-frequency current outputted from FETs 1 and 2, it transmits the high-frequency current to the side of an exciting coil 3 without loss, whereby the lighting efficiency of an electrodeless lamp can be improved. Moreover, the synthesized impedance of the said series circuit becomes inductive to the third higher harmonic current or over of the said high frequency current, so the fifth higher harmonic waves or over become hard to be transmitted to the side of the exciting coil 3, therefore the radiation noise caused by the fifth or over higher harmonic components radiated from the said exciting coil 3 can be reduced, and the adverse effect on other equipment by this radiative noise can be lessened. Moreover, since the said synthesized impedance becomes inductive to higher harmonic components, the occurrence of ringing at FETs 1 and 2 can be suppressed.

Filed: 1984-09-11
Abstract: PURPOSE:To facilitate the manufacture and to prevent deterioration in the performance by forming a GaAs solar cell part on a Ge plane by a gas-phase growing method using an organic metal and incorporating a diode in a substrate. CONSTITUTION:A p type Si diffusion part 2 is formed on a lower plane of an n type Si substrate 1 and the substrate 1 and the diffusion part 2 composes a by-pass diode. A Ge layer 5 is formed on the substrate 1 and a p-n junction part 8 of a GaAs solar cell composed of an n type GaAs layer 6 and a p type GaAs layer is formed on the layer 5. A GaAlAs layer 10 is arranged on the layer 7. The junction part 8 and the layer 10 are formed by gas-phase growth using an organic metal which is effected at a relatively low temperature. Accordingly, the manufacture is easy and there is no possibility of deterioration of the performance even if the p-n junction is formed on the substrate by diffusion or the like. Also there is no need of externally attaching a diode for protection of a reverse voltage so that the lightening of the weight of an array can be contrived. Furthermore, by using a Ge substrate, the substrate 1 and the layer 5 can be unified.

Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To precisely judge a period even if a dispersion of defect position or detection miss is caused by a specified algorithm for performing a calculation by use of the data of the scanning directional MD position and lateral TD position of a detected defect and providing a basic period to determine the multiple. SOLUTION: In a main computer 41, a detected defect is sorted in TD position, and its defect number is stored in a two-dimensional buffer. The continued parts of TD are taken out and grouped to determine a typical TD position. The difference in MD position of adjacent defects of one group is calculated, and the same differential values are collected to one. Those having differential values having a small integral multiple are collected as basic period, and those of a large value are collected as integral multiple period. Low basic periods such as half period in MD space, if present, are collected. It is judged whether the individual defect is the defect corresponding to the basic period or not, and the number within the period defect is calculated.  Further, when defect groups are present in a plurality of TD positions, they are successively taken out by one group, and this operation is repeated. The judgment result by the above procedure is outputted to a book.
