Abstract: PURPOSE:To estimate the amount of looseness without removing an inner plate and the like every time as the method for inspecting the abrasion and the elongation of a handrail chain. CONSTITUTION:A main body 20 is provided at a footstep 6. Scales 30 are provided on moving handrails 12 on both sides. After the lifting operation, the movement is stopped. The vertical sides of the handrail chains are pulled with the hands, and the amplitude, i.e., the amount of looseness, is measured with a steel scale 14. The corresponding relative displacement Y is read, and the actually measured data of the corresponding relationship are obtained. Thereafter, the relative displacement Y is read. Thus, the maintenance and inspecting works can be simplified. On-site setting is individually performed based on the above described actually measured data. The maintenance and inspection are made easy by reading the externally displayed value on the scale at the next working time.

IPC: H01H71/02
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To prevent a main circuit terminal from being short-circuited with a mounting device when a detecting bar is inserted to a thread fastening hole through a detecting hole from the outside of a panel by setting the outer diameter of the detecting hole larger than the outer diameter of the thread fastening hole. SOLUTION: The detecting bar 10A of a voltage detecting device 10 is passed through a detecting hole 14 and a thread fastening hole 7, and the tip of the detecting bar 10A is brought into contact with a terminal screw 12 to detect the voltage. When the detecting bar 10A is substantially horizontally inserted to the detecting hole 14, a main circuit terminal 11 is never short-circuited with a mounting device 1 since the detecting bar 10A only touches the edge of the insulating thread fastening hole 7 even if the hand holding the detecting bar is shaken. Thus, a worker can safely execute the detection. The part to be contact with the tip of the detecting bar 10A may be the plate-like main circuit terminal 11 without being limited to the terminal screw 12, and it is sufficient for the tip to be in conductive contact with the main circuit terminal 11.

Abstract: PURPOSE:To markedly enhance the efficiency in using an ink ribbon, by controlling the feed quantity of the ink ribbon at the time of correction, according to the kind of the ink ribbon being mounted. CONSTITUTION:When a correcting command is given, the relevant type of a daisy wheel is selected for correction, and a type-selecting motor is so driven that the type is brought to a position at which an impact for correction can be given to the type by a recording head 3. If required, a carriage 1 is moved to a correcting position. Next, a correction tape 8 is shifted up to a correcting position by rotating a cam 15. Then, the kind of the correction tape is discriminated based on the content of a correction tape kind register. In the case of a general correctable ribbon, the ink ribbon 6 is taken up to such an extent that the ribbon 6 is not damaged or broken. In the case of a multi-ink ribbon or a fabric ink ribbon which has a relatively high strength, the ink ribbon 6 is taken up to such a very slight extent that the ribbon is not damaged or broken, the extent being less than that in the case of the correctable ribbon. Then, an impact for correction is given to the ribbon by the head 3, thereby performing correcting.

Abstract: PURPOSE:To realize the quick detection for the error of the data signal at the transmission side, by transmitting the data to each terminal unit connected to the loop- type transmission line and then transferring the transmitted data to the central unit for checking. CONSTITUTION:The serial loop-type connection is given via common transmission line 3 between central unit 1 and terminal units 2-1-2-n. Then central transmitter 4 for data transmission and central receiver 5 for data reception are provided to unit 1; and terminal receivers 6-1-6-n are connected in series to line 3 for units 2-1-2-n respectively. Thus processors 7-1-7-n of units 2-1-2-n process the data transmitted from transmitter 4 and received, and at the same time terminal transmitters 8-1-8-n are connected directly to terminal receivers 6-1-6-n each. Then the data are transmitted to the next terminal units from transmitters 8-1-8-n as soon as the data signals enter processors 7-1-7-n, and then the data are sent back to unit 1 from the last terminal unit via the loop-type transmission line. Thus the central unit itself gives the error checking to the data transmitted.
