Title: Earthquake-proof reinforcement method for concrete pole and earthquake-proof reinforcement device therefor
Inventor: MIYAZAKI TOSHINOBU
IPC: E01D21/00
Filed: 1995-02-27
Abstract: PURPOSE: To heighten earthquake-proof strength of a concrete pole by simply reinforcing the concrete pole on an existing viaduct, and by preventing their resonance in an earthquake. CONSTITUTION: An earthquake-proof reinforcement device for a concrete pole 1 is composed of a steel pipe part 10 and a framework 20. The steel pipe part 10 consists of a pair of half-split steel pipes, each of which has a packing member to be brought into close contact with the periphery of the concrete pole 1 on the inside thereof and which are integrally assembled with bolts, and a pair of half-split seat plates, each of which is fixed to the bottom of each of the half-split steel pipes. The framework 20 is fastened to the seat plates and holds a protrusion part 3 of a viaduct.  When a natural frequency of the concrete pole 1 is given as 3.0Hz or more by the reinforcement device, it is made clearly different from a natural frequency of the viaduct, 2.0 to 2.3Hz, and hence such a trouble that the concrete pole 1 resonates with the viaduct does not occur even if the viaduct vibrates. Furthermore, the steel pipe part 10 is made in half-split assemblages and the protrusion part 3 is held and fastened by the framework 20, and hence the concrete pole 1 existing can be simply reinforced.

Title: Burst signal detecting circuit
Inventor: SHIYOUJI NOBORU
IPC: H04L7/10
Filed: 1981-03-17
Abstract: PURPOSE:To detect the break of a burst input, by using a clock regenerating circuit, which outputs a spacific number if pulses for one trigger input, and a circuit which detects that the output of the clock regenerating circuit is broken or intervals of pulses from the clock regenerating circuit are not constant. CONSTITUTION:When a burst CMI code is received, an output control circuit 4 is turned on by the brust rise signal, and the output of a decoder 3 is outputted. A clock regenerating circuit I outputs three continuous clocks for every change of the input from ''1'' to ''0''. The first delay circuit 6 compensates the lag due to the delay (0.75T) of the decoder 3, and clocks 10 and 11 delayed by one period and two periods are obtained in the second and the third delay circuits 7 and 8 respectively and are supplied to an OR circuit 12 to obtain regenerated clocks. The break of the input and the drop-out of regenerated clocks due to the disturbance of the CMI code rule are detected by a monostable multivibrator (T<pulse width<2T) having the retrigger function.

As a method of calculating the thickness data of paper sheets entering the bin 20 of the copying paper sheets, for example, pulses of a tachometer when the elevating device pulls up the stack 33 to the upper limit switch are counted. After that, feeding of paper sheets from the stack 33 is started, and at this time, the number of paper sheets is calculated. After a designated number of paper sheets are counted, the height of the paper stack 33 is again calculated. When the change in paper sheet height is divided by the number of paper sheets fed out from the bin, the thickness of one sheet can be accurately found.
