Title: Footstep
Inventor: TAKAHASHI EIZO
IPC: E06C9/04
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To provide a footstep which enables to rise and fall with safety by forming a tread at the tip on both sides and in the intermediate part and further extending the tread at the tip on both ends and then bending inwardly the tread and connecting that to the intermediate part on the side. SOLUTION: Except for a leg 3, an iron-made core bar 2 is covered with a synthetic resin 4, thereby forming a footstep 1. Treads 5 and 6 are formed at the tip of both sides 7 of the footstep 1 and the intermediate part. Non-slip patterns 8 and 9 are formed on the top of the treads 5 and 6 while a grip 10 is formed on the tread 5. After the tread 5 at the tip is further extended on both ends, it is inwardly bent in the rear so that it may be connected to the intermediate part of the sides 7. A large number of footsteps are set up in the vertical direction on a manhole or a bulkhead or the like. Therefore, this construction makes it possible for any one who rises and falls, to climb up and down with his or her feet with safety extendingly in contact with the tread.

Title: Multi-gradation printer
Inventor: YAMAKAWA TADASHI
IPC: H04N1/23
Filed: 1984-03-22
Abstract: PURPOSE:To reproduce a multi-value picture at a very high speed by transferring a picture data in response to a required gradation number in parallel, storing in parallel it in a storage circuit and counting a value of a stored picture data as an initial value. CONSTITUTION:When output signals X1-X5 of LED drivers 103-1-103-5 are logical 0, since an output terminal is connected to common, corresponding LED 101-1-101-5 are lighted, and when the output signals are logical 1, since the output terminal is released from a common potential, the corresponding LED 101-1-101-5 are extinguished. Thus, the LED101-1 generates optical energy by the period corresponding to 8/15 of the maximum lighting period, the LED102-2 generates no optical energy at all and the LED101-3 generates optical energy over the full period of the maximum lighting period. The value of the picture data stored in this way is counted as the initial value and the picture having a density corresponding to the input picture data is reproduced on a recording paper sheet.
