Title: Scrap preheating device
Inventor: TAKAHASHI TSUTOMU
IPC: F27D13/00
Filed: 1994-08-12
Abstract: PURPOSE:To prevent the oxidation and melting of scrap due to a local overheating by bringing the scrap thrown into a metal melting furnace into contact with exhaust gas exhausted from the metal melting furnace to be preheated. CONSTITUTION:Scraps S1, S2 charged into a column member 21 from a scrap charging port 35 are charged into respective preheating chambers 51a and 51b by opening and closing a gate 40. They are sequentially moved to the lower side preheating chamber 51b for every prescribed preheating holding time, and thrown into a metal melting furnace 1 from a scrap exhaust port 37 after a plurality of times of preheating. Exhaust gas from the melting furnace 1 is divided into flows in the lower part of the column member 21 and a part of them enters the uppermost preheating chamber 51a via a division flow duct, flows as a descending flow in the scrap S1 layer of the preheating chamber 51a to preheat the scrap S1, layer, and then, flows out of the exhaust duct of the lower preheating chamber 51b. Residual gas flows as an ascending flow in the scrap S2 layer of the other preheating chamber 51b to preheat the scrap S2, and then flows out of the exhaust duct. Thus, high preheating efficiency can be obtained.

Title: Method and apparatus for judging cavitation in internal combustion engine
Inventor: MIZOMATA SUKEYOSHI
IPC: G01M15/00
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To judge at once where cavitation is maximized in one rotation of an internal combustion engine by judging the peak period of the voltage strength of a cavitation signal corresponding to a crank angle. SOLUTION: A ultrasonic signal generated in the crash of a cavity generated in the fuel injection system of an internal combustion engine is received by a piezo-electric element 7 and subjected to the signal process by a detecting rectifier 4 and an amplifier 5 after noises are removed by HPF 3 through a detector 1 and a head amplifier 5. On the other hand, a crank angle signal detector 12 detects a crank angle signal 14 of an engine. An electric signal subjected to the signal process is represented as an electric signal envelope corresponding to cavitation strength so that the peak value is judged by a voltage judging means 11. Further, the crank angle corresponding to the judging time is judged by a crank angle judging means 13. The result of the judgment is indicated as the peak value of the cavitation strength and the time (crank angle) on a indicating part 6.

Title: Overhead and flat simultaneous welding machine
Inventor: SHIRAISHI AKIHO
IPC: B23K9/00
Filed: 1985-09-27
Abstract: PURPOSE:To make a welding bead monitorable from the front and to increase the aiming accuracy of a weld line by separating the main body base from a torch supporting base and by providing a wide monitoring space before and behind the torch supporting base. CONSTITUTION:A roller 5 is oppositely fitted so as to pinch a tube panel 4 from the upper and lower on the main body base 1 of the upper and lower simultaneous welding machine, and the roller 5 is located at the upper part considerably from the foundation of the lower part. An overhead welding torch 2 and flat welding torch 3 are arranged adjoining to the roller 5. An overhead welding torch 2 and the torch supporting base 6 which supports the roller 5 are fitted to the main body base by bolts and the height of this base 6 is made higher than the conventional one. Due to the main body base 1 before and behind the base 6 being set lower a monitoring space S is formed in such extent that a worker can come in and out before and behind the base 6. The weld aiming accuracy is therefore increased because of the worker being able to monitor by coming in and out of the inside of the monitoring space S while under welding.

Title: Powder molding machine
Inventor: NAKAGAWA TAKEO
IPC: B30B15/30
Filed: 1992-07-17
Abstract: PURPOSE:To uniformalize the density of the molding powder to be packed into a die by adopting a mechanism which passes a feeder for the molding powder over the die while laterally oscillating the feeder. CONSTITUTION:A powder feed section 1 formed to an inverted bowl shape is connected to a hopper 30 by a flexible hose 36 to supply the molding powder to the die 2. An arm 31 of the powder feed section 1 is constituted as a rack gear in such a manner that this arm can be advanced and retreated by rotation of a pinion gear 38 of a motor 32 for advancing and retreating. A casing 34 oscillates the powder feed section 1 laterally around a pivot shaft 35 when the eccentric cam 39 of a motor 33 for lateral oscillation rotates. As a result, the powder feed section 1 is so controlled as to stroke the surface of the molding powder packed in the die 2 while oscillating laterally at the time the powder feed section 1 retreats from the surface of the die 2. The density is thereby uniformalized and the strength is maintained.

Inventor: FUJIMAKI MUNEHISA
IPC: C03B37/025
Filed: 1992-08-10

Title: Apparatus for retrieving data track
Inventor: TANEMURA TAKASHI
IPC: G11B7/085
Filed: 1993-08-27
Abstract: PURPOSE:To shorten the re-retreating time by moving a head after detecting a moving direction of the head and retreating the head when a speed of the head to traverse a track is not higher than a predetermined value if the head fails to retreat from the track. CONSTITUTION:A galvano mirror 4 is driven in response to a track error signal from a differential amplifier 16. When the galvano mirror fails to move light spots 10-12 to a target track, a shifting angle of the galvano mirror is adjusted to a predetermined target value. At this time, a controller 30 controls a position 8 so that a relative moving speed of the light spot and a head 1 becomes 0. The controller 30 detects the track error signal with a rise timing of a detecting signal corresponding to a reflecting light on the track via a photodetector 13 and a binary circuit 17, thereby to detect a moving direction of the head and switch a polarity of a generating circuit 20 which generates a speed for the head to traverse the track. When a detecting circuit 19 to detect the traversing speed outputs a signal, the controller makes the light, spots trace the track. Accordingly, the seeking time at a re-retreating occasion is shortened.

Title: Device and method for experiencing visual field of spectacles and record medium
Inventor: KOMATSU AKIRA
IPC: G02C7/06
Filed: 1998-07-28
Abstract: PROBLEM TO BE SOLVED: To experience a shake when the head is moved by forming as a visual-field image a distorted image obtained by giving the distortion of a lens to an image changing as the visual field direction is changed when the angle of the face wearing spectacles is changed. SOLUTION: The visual-field image is the distorted image obtained by giving the distortion of the lens to the image which changes as the visual field direction is changed when the angle of the face wearing the spectacles is changed. Namely, a progressive multifocal lens has the problem that a shake is felt owing to a change in visual field direction when the head is moved since a body is viewed while distorted. The shake felt when the heat is moved is hardly to feel in a still image. For the purpose, an image processing part 13 performs a process for giving the distortion of the lens to a moving picture showing the change of the visual field corresponding to the movement of the head sensed by a head motion sensor 28 to display a distorted image showing the motion, thereby simulating the shake felt as if the face wearing the spectacles of progressive multifocal lenses were shaken.
