Title: Dioxin generation preventing method for scrap melting furnace and its pre-heating device, and dioxin generation preventing device
Inventor: TABUCHI SEIGO
IPC: C21C5/52
Filed: 1991-11-07
Abstract: PURPOSE:To prevent dioxin from generating by a method wherein an exhaust gas discharged from a scrap melting furnace (electric furnace) is burnt by a high combustion to eliminate carbon monoxide in the exhaust gas. CONSTITUTION:An exhaust gas discharged from a scrap melting furnace (electric furnace) 1 enters a combustion chamber 20 through a sliding pipe 19. Then, the exhaust gas discharged from the combustion chamber 20, e.g. passes through a bucket 25 for scrap preheating under a condition in which a switching valve 23 of a by-pass 22 is opened, and a switching valve 24 of the by-pass 22 is closed, and is introduced to a combustion tower 2 under a condition in which a switching valve 29 is opened. When the operation of the scrap melting furnace 1 starts, the quantity of carbon monoxide increases. However, for a few minutes from the start of power connection of the scrap melting furnace 1, the quantity of carbon monoxide is lower than the explosion limit, and carbon monoxide does not burn. For this reason, the inside of the combustion tower 2 is kept at a high temperature which is 800 deg.C or higher from the start of a power connection of the scrap melting furnace 1 to burn and make the exhaust gas stay for 2 seconds or longer, and thus, dioxin is prevented from generating.

Abstract: PROBLEM TO BE SOLVED: To prevent breaking into a room by mounting a camera and a speaker within a monitor camera apparatus and providing a monitor and a microphone for a monitoring center so as to display the video signal of the camera on the monitor and to output voice obtained by the microphone from the speaker to restrict the behavior of an intruder. SOLUTION: Plural monitor camera apparatuses 1a and 1b are arranged in a room to be monitored 21 and a switching switch 23, the monitor 24 and the microphone 25 are installed at the monitoring center 22. Then the video signal from each monitor camera 11 is inputted to the switching switch 23 to switch a picture from a desired monitor camera 11 with an optional timing and it is outputted to the monitor 24 to display. When a monitoring personnel watching the monitor 24 finds the intruder, the personnel properly warns to the intruder's behavior with voice by means of the microphone 25 through the speaker 9. Thereby the intruder's behavior is restricted to prevent breaking into the room.

Title: Image processing device
Inventor: KATO SHINICHI
IPC: G01B11/06
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To obtain an image processing device which keeps the color of an output image in the same state all the time despite a change in a quantity of fixing oil by making an image-processing correction for an image data read by an image input means, based on an image-processing correction coefficient fetched from an image-processing-coefficient storage means. SOLUTION: A fixing oil quantity measuring sensor optically measures a quantity of fixing oil on the surface of a fixing roller, and the optical measurement is conducted by means of brightness measurement, density measurement, or chromaticity measurement. From a transferred digital signal, a fixing-oil monitor 39 calculates a present quantity of fixing oil according to a lookup table. Based on the calculated quantity of fixing oil, an image-processing correction coefficient corresponding to the quantity of fixing oil is fetched from a ROM 37, and is set in the various circuits 31-35 of an image processing part 30.  In the case the quantity of fixing oil is larger than a reference value, the value of the density of an output image decreases, therefore a coefficient for making the density higher than the reference value is sent to the various circuits 31-35 of the image processing art 30.

Title: Generator controller for hybrid electric vehicle
Inventor: ARAI YOSHIHIDE
IPC: B60L50/15
Filed: 1994-12-22
Abstract: PURPOSE: To prevent the drive feeling from lowering by idling the engine during next control period when the smoothed value of power consumption of a motor drops below the minimum output of a generator. CONSTITUTION: When the power consumption Pm of a motor drops below a level Px in the vicinity of the minimum output PgMin of a generator, idling of an engine is started and the throttle is fully opened when the power consumption Pm exceeds a level Py in the vicinity of minimum output PgMin of the generator. Since the idling period B' coincides with the period where the power consumption Pm of motor lowers, deterioration of drive feeling due to actualization of noise can be suppressed.

Abstract: PURPOSE: To decrease the seizure and noise of a brake by decreasing uneven wear of a brake pad. CONSTITUTION: A disc brake 10 comprises a caliper housing 11 having a main body member 12 and an arm member 14 connected to each other by a bridge 16. The leading side of the arm member 14, i.e., the side located on the upstream side with respect to the direction of normal rotation of the rotor of the disc brake, is more rigid than the trailing side of the arm member. A set of stiffening fibers 28, 30 is provided respectively in first and second bridge portions 22, 24 of the bridge 16 to make the density of the stiffening fibers 28 in the first bridge portion 22 greater than that of the stiffening fibers 30 in the second bridge portion 24, for example, to produce a difference in rigidity between the leading and trailing sides of the arm member. Therefore, a brake pad supported by the arm is evenly pressed against a rotor at its leading and trailing sides to thereby avoid uneven wear of the pad.

Title: Resist treatment apparatus
Inventor: AOYAMA HIDEHIKO
IPC: H01L21/677
Filed: 1993-12-21
Abstract: PURPOSE:To eliminate a time waiting for the arrival of a conveying robot from the finish of a resist treatment to the start of conveyance by a method wherein a finish forecast flag is set on a resist treatment unit by a finish announcement unit and a robot controller transfers the conveying robot to that resist treatment unit based on the flag. CONSTITUTION:A forecast finish time calculating unit 12 calculates a treatment finish time to be forecast by subtracting the transfer time of a conveying robot 16 from the treatment finish time of a wafer 18 when a resist treatment is started by a resist treatment unit. A lapse of time counting unit 13 starts counting when the resist treatment is started. A finish forecast unit 14 compares the forecast finish time with the lapse of time and, when both of them agree with each other, sets a finish forecast flag. A robot controller 17 transfers the conveying robot 16 to that resist treatment unit 2 to eliminate a time waiting for the arrival of the conveying robot from the finish of the resist treatment to the start of conveyance. With this constitution, a time required for the whole treatment process can be reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a game machine capable of connecting an electric component arranged on a glass frame to an electric control board arranged on the back side of a game panel and capable of expanding the flexibility of the game panel while reducing the machining time and the manufacturing cost of the game panel. SOLUTION: A lamp 3c on the glass frame 2 and the lamp control board 12 arranged on the back side of the game panel 5 are connected by inserting a connecting component 15 into the through hole 5a of the game panel 5 formed sufficiently larger than the outer shape of the connecting component 15. Since no high precision is required for the through hole 5a, the through hole 5a can be easily bored on the game panel made of veneer, therefore the machining time and the manufacturing cost of the game panel 5 can be reduced. When only the game panel 5 is replaced, another connecting component 15 can be inserted as it is because the through hole 5a is formed sufficiently larger than the outer shape of the connecting component 15, thus the flexibility of the game panel 5 can be expanded.
