Title: Operating method of blast furnace
Inventor: KURIHARA JIYUNSAKU
IPC: C21B5/00
Filed: 1979-06-28
Abstract: PURPOSE:To lower the fuel ratio of a blast furnace and lower the cost of cast iron by blasting only the hot wind without mixing cold wind therein during the furnace condition stabilizing period of the blast furnace. CONSTITUTION:The decision of whether the blast furnace conditions are stable or not is accomplished by the quantitative determination of the changes in the furnace conditions by a computer based on empirical judgement. Namely, overall decisions GO, STOP AND BACK are made by using eight factors including in-furnace full- pressure loss, shaft part pressure loss..., etc. This method is executed at the decision of GO. Namely, cold wind will leak from a butterfly valve 13 when the butterfly valve is only closed and therefore a mixing cold wind shut-off valve 14 being a gate valve is also closed to shut off the cold wind and blast the hot wind alone. On the other hand, at the decision of STOP or BACK, the mixing cold wind shut-off valve 14 and the butterfly valve 13 are both opened and a conventional cold wind mixing method is executed by regulating the opening of the butterfly valve 13.

Title: Optical switch to be controlled
Inventor: SHIRASAWA SUSUMU
IPC: H04B10/00
Filed: 1984-04-24
Abstract: PURPOSE:To attain two ways of connection by one drive by connecting two- terminal optical switch elements located oppositely having two states of cross connection and parallel connection in a lattice form and driving each switch to bring a switch at a cross point of input/output to be connected into parallel connecting state. CONSTITUTION:It is supposed that an optical input terminal 1 and an optical output terminal C are to be connected. When the initial state of the optical switch elements A1-C3 is all in the cross connecting state, 6 ways of drive modes exist, and when a restriction that only an optical switch element placed at a cross point between an input terminal and an output terminal to be connected is brought into the parallel connecting state is given, only the optical switch C1 is brought into the parallel connecting state. In this case, the number of optical switch elements to be driven is minimized. Thus, the two connections of an optical transmitter 12, an optical receiver 22 and an optical transmitter 21, an optical receiver 11 are completed at the same time.

Title: Uniformly sprinkling device
Inventor: ROBAATO DOYUIBETSUTAAZU
IPC: B22D11/108
Filed: 1990-03-29
Abstract: PURPOSE: To uniformly spread a massive material onto a circular surface by suspending a rotating part from a drive shaft, constituting a distribution container recessed and provided with a trough-like member around the drive shaft at its bottom and supporting a cover provided with scrapers on the bottom flank in the fixing portion thereof. CONSTITUTION: A heat shielding body 15 rotates in such a manner that an outflow opening opens during rotation. When a closing slide opens slowly during the rotation of the distribution container, the lifting part falls together with the material to be distributed. The massive material falls onto a steel bath and forms a carpet-like laminated layer. During the outflow of the material, the product already existing on the flat portion in the trough 12 is struck by the stationary scrapes 21, 22. When a lifting cover 4 arrives at the bottom position, the scrapers 21, 22 wipe away the flat part of the rotating part 2 and the product is forced into the trough 12 to empty the distribution vessel. At the point of this time, a limit switch operates and the lifting portion is commanded to occupy its apex position.  After the lapse of some time, the entire amt. of the material is delivered from the distribution vessel and is uniformly spread on the surface layer of the steel bath.

After the slicing of the wave form a medium value MC of the mask mark and a medium value PC of the plate mark are respectively decided, a difference of these are decided and alignment processing is performed. As a result, alignment signals of the substrate and the mask are simultaneously inputted.

Title: Lubricating oil cooling device for gear transmission
Inventor: IMAEDA FUMIMORI
IPC: F16H57/04
Filed: 1991-04-16
Abstract: PURPOSE:To prevent lubricating oil from being fixed in a cooling device by effecting control so that oil is forcibly circulated each time given vehicle running state frequency is detected, in a device which forcibly circulates oil to an oil cooler according to the temperature of lubricating oil in a gear device. CONSTITUTION:During the stop of an engine, a pump 5 with the aid of which lubricating oil is forcibly circulated is stopped. When the engine is run, the temperature of oil in the oil reservoir of a differential carrier 2 is orderly measured by means of an oil temperature sensor 6, based on the measurement, decision is effected by a control means 7 to control running of the pump 5. Namely, since, when an oil temperature is below T1, a viscosity value of lubricating oil is high and a load on the pump 5 is high, forced circulation is not effected. However, when the oil temperature exceeds T1, it is decided by a shift position detecting means 8 whether or not a shift position enters a reverse range, and when it enters the range, the pump 5 is run, and lubricating oil is forcibly circulated. This constitution prevents lubricating oil from being fixed in the pump 5.

Abstract: PURPOSE:To improve precision in position-alignment, by performing positionalignment by the use reflected light, which is a part of exposing lights, coming from a position-alignment pattern of an exposed material. CONSTITUTION:Position-alignment light 11a emitted from a position-alignment light source 10 is irregularly reflected on a position-alignment referential pattern which is imaged on a wafer 6, and a part 11d of the irregular reflecting light passes through a pattern reflecting lens 5 to be projected on a position 13 of a mask 4.

Abstract: PURPOSE:To detect light output and wavelength of light to be detected, from the signal of each photo detector, and to miniaturize the entire system, by providing optical waveguides constituting directional coupling and a plurality of photo detectors optically coupled with said optical waveguides. CONSTITUTION:On a substrate, an optical waveguide 1 and an optical waveguide 2 constitute a directional coupler; a photo detector 3 and a photo detector 4 optically coupled with each of the light output side ends are installed.

As to the directional coupler, the output sum of both of the photo detectors is constant even when the wavelength changes. As a result, by obtaining the summed signal of the optical detector 3 and the optical detector 4 with an adder 13, the light output of the light to be detected can be detected. Thereby the light output and the wavelength of the light to be detected can be detected, control such as tracking of desired light output and wavelength is enabled, and a small-sized photo detector can be realized by integrating components.
