Title: Ultra-fine grain ferrite steel and preparation thereof
Inventor: YADA HIROSHI
IPC: C22C38/04
Filed: 1983-05-02
Abstract: PURPOSE:To obtain ultra-fine grain ferrite steel, especially, in a hot rolling state, by processing steel containing C and Mn respectively in a predetermined ratio by prescribing a sum total draft in a specific temp. region at the final stage of hot processing in a process for cooling said steel from a temp. of an Ac3 transformation point or more. CONSTITUTION:Steel containing 0.02-0.3% of C and 0.1-2% of Mn is subjected to hot processing in a process for cooling said steel from an Ac3 transformation point and, in the final stage of hot processing of said steel, processing such that a sum total draft in one or more times of rollings within one sec in the vicinity of an Ar3 point, that is, a temp. range of (Ar1+50 deg.C)-(Ar3+100 deg.C) is 50% or more is applied to said steel. Subsequently, steel after hot rolling is desirably cooled at a cooling speed of 20 deg.C/sec or more to allow the temp. thereof to reach 600 deg.C or less. As a result, ultra-fine grain ferrite steel with hypo-eutectoid steel with its main component containing no special alloying element such as Nb is obtained, especially in the state of hot rolling.

Title: Position detector for work vehicle guiding device using beam light
Inventor: YOSHIKAWA KOJI
IPC: G05D1/02
Filed: 1988-03-30
Abstract: PURPOSE:To detect the position of a work vehicle body without using any exclusive sensor, etc., by measuring the time covering the time point when a photodetecting means receives the guiding beam light through its next receiving time point and discriminating the position of the vehicle body. CONSTITUTION:A beam light projecting device 1 is set at the ceiling side of a path so that the device 1 can perform the repetitive reciprocating scans of the guiding beam light A along the lengthwise direction of the path. A work vehicle body V contains a pair of front and back photodetectors S1 and S2 for its drive control. Then a timer contained in a controller counts two continuous times T1 and T2 covering the time point when the front photodetector S1 receives the light A through its next receiving time point. Thus the position of the body V is discriminated in the lengthwise direction of the work process based on the ratio between both times T1 and T2. As a result, the position of the body V can be detected on a set locus without using any exclusive detecting means like a sensor for measurement of distance, etc.

Title: Electrical driving device
Inventor: WATANABE NOBUTAKA
IPC: G03B17/42
Filed: 1982-05-11
Abstract: PURPOSE:To stabilize a long-sized film under exposure and to take up the film safely and surely, by braking the driving mechanism for a long-sized film magazine with an electromagnetic brake when the electric power supply to a shutter charging mechanism and a sprocket driving mechanism is interrupted. CONSTITUTION:When photographing is completed, the winding switch 47 of a camera 1 turns on and a film is wound with a main electrical driving device 2. The switch 47 turns off upon completion of the winding, then a transistor Q1 is turned off by the control circuit 50 of the device 2, by which the electric supply to a motor 19 of a shutter charging mechanism and a sprocket driving mechanism is interrupted. Then, a motor 29 of a long-sized magazine 3 is turned by interia and a generator is operated so that the coil 45 of an electromagnet is excited by a transistor Q2 turned on by the electric discharge of a capacitor C1 and the magazine driving mechanism is braked simultaneously with stopping of the shutter charging mechanism and sprocket mechanism. The long-sized film is thus stabilized under exposure even if the film is subjected to continuous photographing and the long-sized film is taken up safely and surely.

Title: Melting furnace for incineration residue of waste
Inventor: NAKAO TSUYOSHI
IPC: F23J1/00
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To obtain a furnace for melting incineration ash with a current flowing between electrodes through a molten slag in a furnace tank in which short circuit is prevented between the electrodes due to fused salt by providing a sleeve for insulating the electrode from a fused salt layer existing between the electrodes on a fused stag layer movably up and down. SOLUTION: When an incineration residue 11 is thrown into a furnace from the supply port 3 of a furnace body 1, the incineration residue 11 is precipitated gradually into a fused salt layer 10 due to the difference of specific gravity and fused gradually. The slag component and the salt component contained in the incineration residue 11 are precipitated, separately, into a fused slag layer 9 and the fused salt layer 10 due to the difference of specific gravity and the fused salt layer 10 is formed thicker gradually. Since the specific gravity of an insulation sleeve 7 is set between those of the fused slag and the fused salt, the insulation sleeve 7 is floating always at the position of the fused salt layer 10 while being guided by an electrode 2.  Since the insulation sleeve 7 separates the electrode 2 and the fused salt layer 10, short circuit is prevented between them and a stabilized operation is ensured.

Inventor: SHIMIZU MASAMI
IPC: G03B7/08
Filed: 1983-05-09
Abstract: PURPOSE:To confirm an exposure arithmetic value by displaying the exposure arithmetic value on an external indicator, at the time of a stopped-down actual diaphragm priority mode. CONSTITUTION:After setting to a stopped-down actual diaphragm priority mode, the first stroke of a release button is pushed in. As a result, a photometric circuit is operated, and an arithmetic value of a shutter second time by an actual diaphragm is displayed by the LED26 of display body 18 in a finder. At the same time, the operated value of the shutter second time is displayed by using the display part of four digits of an external indicator. At the time of the stopped-down actual diaphragm priority, an eyepiece is closed in order to reduce a photometric error due to back incident light to the finder. Accordingly, the display in the finder cannot be seen, but since the exposure arithmetic value is displayed on the external indicator, a photographer can confirm visually the shutter second time. By displaying in this way, the exposure arithmetic value can be confirmed.

CONSTITUTION:When a current collector 9 comes into contact with trolley lines 10 and 11 to press said lines in the arrowed direction P, a bending load in the arrowed direction P is applied on a supporting equipment 15 around the fulcrum corresponding to the lower end thereof. However, the bending load can be borne by a parapet 5 via a bumber mechanism 46 and a link bolt 47, on account of which the supporting equipment 15 will not be bent or deformed under pressing force of the current collector 9. In addition, the supporting equipment 15 is subjected to a bending moment created in the longitudinal direction of a rail around the lower end of the supporting equipment when the position of a link bolt 47 with respect to the bolt 20 of a rail 8 is changed relatively in the longitudinal direction of the rail, under influence of varied temperature, the moment can be cancelled by displacement of a piston 51 against resilient force of a spring 50.

Title: Motive power transmitting mechanism for tape take-up driver of tape recorder
Inventor: ONOZAWA MASAO
IPC: G11B15/26
Filed: 1985-04-15
Abstract: PURPOSE:To break the transmission of drive power at the final stage of rapid traverse or rewinding mode of a tape by providing the rapid traversing and rewinding gears of large diameters separately from an operating pulley to attach them to a shaft with an operating shaft defined as an axial core and providing a clutch between both gears and the pulley for connection. CONSTITUTION:When an operating pulley 6 is rotated, an operating shaft 3 coupled to the pulley 6 via a clutch 10 is rotated. Then a recording/reproduction driving gear 14 of a small diameter is rotated. Thus the drive power of the pulley 6 is transmitted in the form of the drive power for recording/reproduction of a tape by connecting a recording/reproduction gear system to the gear 14. When the tape is not fed any more at the final stage of the tape recording or reproducing mode, the load is applied to the shaft 3. Then the transmission of the drive power is cut off between the pulley 6 and the clutch 10. This prevents the large tension applied to the pulley 6.
