Title: Crankshaft
Inventor: OZEKI HISASHI
IPC: F02B75/22
Filed: 1993-04-16
Abstract: PURPOSE:To reduce longitudinal length of an engine and improve mountability of the engine by reducing both end counter weights which cancel unbalanceness of a whole crankshaft in weight and thickness compared to other counter weights. CONSTITUTION:A first and a fifth counter weights 26-1, 26-5 located on the sides of both ends 4A, 4B of a crankshaft 4 are set not greater than second to fourth counter weights 26-2, 26-3, 26-4 in weight. Smooth rotational operation of the crank-shaft 4 is kept by holding balances of the first to fifth counter weights 26-1, 26-2, 26-3, 26-4, 26-5. Thickness TA, TE of the first and fifth counter weights are thus smaller than thicknesses TB, TC, TD of the second to fourth counter weights. Total length of the crank-shaft 4 can be reduced, and longitudinal length of a V-tape engine is reduced.

Abstract: PURPOSE:To easily open and close an inspection cover so as to improve safety with no interference at the time of opening and closing the cover by sliding the inspection cover, for inspecting and repairing a floor display, vertically along a guide arranged in a position wider than a width of an elevator gate. CONSTITUTION:In the case of inspection and repair for lighting devices or the like in an indicator main unit 8 in which a floor display device 9 is housed, a handle 2b is operated to the upper from a cage room by a worker, and a back surface of the indicator main unit 8 is opened by moving an inspection cover 2 in a direction of an arrow head 6 along a guide 1. Here even when the guide 1, in which the cover 2 is slid, is arranged in a lift path side 17 from an end part 13a of a door 13 in an opened condition, because no member interferes with the inspection cover 2 when it is opened and closed, work of inspection and repair can be easily performed from an opening port of the inspection cover 2. Also because no space, visible from the lower, is provided between the door placed in opening and an inspection port device, no trouble is generated such that a building structure 16 or the like in a lift path is seen by elevator passengers.

Title: Rolling method for controlling plane camber of rolled material in rolling mill line including vertical rolling stand
Inventor: HAMAUZU SHIYUUICHI
IPC: B21B37/00
Filed: 1980-08-22
Abstract: PURPOSE:To control the direction and size of a plane camber of such a rolled material as a steel slab on the runout side of a rolling pass line, by permitting a roll pair of a vertical rolling stand in a rolling pass line to shift in the direction of breadth of the rolled material. CONSTITUTION:If a runout side camber detector 6 detects a rolled material 1, an arithmetic device 10 operates the size and direction of the camber against the preset pass line, and the output signal of the device 10 is inputted to an arithmetic device 13. The unit 13, by its internally equipped PID control circuit for example, operates the direction and amount of shifting the rolled material 1 on the basis of the said output signal of the unit 10, and sends a command signal to a vertical roll position controller 12. The controller 12, according to this command signal, actuates a shifter 8 to shift a vertical roll pair 4-1, 4-2. If the camber is formed in the illustrated direction, the rolled material 1 is shifted toward the roll 4-2. On the other hand, the unit 13 receives a load signal of each mill for the purpose of controlling the rolling sequence, so that the passing condition of the bottom end of the material to be rolled through the vertical rolling stand 2 can be judged by the unit 13.

Title: Method and device for detecting linear flaw on steel plate
Inventor: SHIOZUMI MOTOHITO
IPC: G01N21/892
Filed: 1990-04-27
Abstract: PURPOSE:To surely detect the linear flaw on the surface of a steel plate extending over the overall length by generating a difference signal between a scanning signal outputted successively from a one-dimensional CCD camera at a prescribed interval against the surface of a running steel plate, and other scanning signal. CONSTITUTION:By a synchronizing signal inputted through a timing controller 16 from a pulse generator (PLG) 30, a video controll 14 scans a one-dimensional CCD camera 10 by a moving amount of a steel plate S, for instance, at every 5mm, and only a red signal among obtained signals is A/D-converted 18 and stored 20. Subsequently, a differential amplifier 22 generates a difference signal by subtracting a signal of an (N + 1)-th scan from a signal of an N-th scan fetched from the memory 20, and a level comparator 24 extracts the difference signal exceeding a reference value as a defect signal. Next, whether the defect signal moves in the width direction of the steel plate S at a prescribed pitch at every scanning interval of the camera 10 in accordance with a synchronizing signal or not is judged 26 by an arithmetic processing, and when it is moving at a prescribed pitch substantially, it is decided that there is continuity, and from its defect signal, a stripe flaw is specified.
