Title: Method and apparatus for operational processing of pulse value in pulse monitor
Inventor: JIKIBA YASUHIRO
IPC: G06F12/00
Filed: 1989-11-20
Abstract: PURPOSE:To accelerate response by detecting the pulse period between the first pulses and setting a reference pulse rate for averaging on the basis of the pulse period and operating a pulse rate value on the basis of averaging of the respective pulse detection values of the set number of pulse periods. CONSTITUTION:When the initial pulse is inputted from a pulse sensor 11, the timer in a microprocessor 9 is turned ON and, when the next pulse is inputted, the timer is turned OFF and the number of pulses of the timer is read and the number of pulse periods averaged by the pulse value (that is, the time) of the timer is set. That is, a reference pulse rate for averaging is determined by the initial pulse period 6. Now, when the pulse rate for averaging is judged to be the average of four pulse periods in the initial pulse period 6, a pulse period 7 is measured and the result thereof is displayed and, when the pulse rate is judged to be the average of six pulse periods in the initial pulse period 6, a pulse period 8 is measured and the result thereof is displayed.

Abstract: PROBLEM TO BE SOLVED: To absorb vibration only with a change in accelerating modes for returning to an initial stage position and to shorten a copying time, regardless of a smallest shape and a low cost by providing plural accelerating modes for returning to the initial stage position, after an original is scanned. SOLUTION: After the scanning of the original is completed, an original scanner is returned to the initial stage position, through a first stage for imparting acceleration working in a direction opposite to that of the scanning of the original, to return a first scanner 29 and a second scanner 30 to the initial stage position, a second stage for imparting the acceleration in some degree, to move the first and second scanners 29 and 30, in a state where a fixed speed is obtained and a third stage where the first and second scanners 29 and 30 approach the initial stage position and the acceleration working in the direction opposite to that in the first stage is imparted.  At this time, the timing, degree, etc., of the acceleration in the first and third stages are made proper so that the amplitude directions of the rolling of a copying machine are negated each other, to make reduce the rolling. Thus, the accelerating mode for each original scanning condition, the accelerating mode most suitable only for a specific condition or an approximate optimum accelerating mode is selected to prevent the rolling and obtain security and reliability.

IPC: C02F3/12
Filed: 1994-11-12
Abstract: PURPOSE: To provide a rational reconstruction method in the case there is no vacant land for a substitutive facility and there is no room for a sewage treatment capacity. CONSTITUTION: First, existing aeration tanks of three systems are changed to oxygen type aeration tanks OAT and since the need for using an initial settling basin is eliminated by the change, the sewage is introduced directly into the aeration tanks OATs without through the initial settling basin where the sewage is subjected to a sewage treatment. Next, the place provided thus far with the initial settling basin is now a vacant space and, therefore, one system of the sewage treatment facility is constructed in this space. The facility to be constructed may be a facility to be substitutively installed during a reconstruction work period or may be a facility to be permanently installed. In succession, the reconstruction of the aged facility used thus far for the sewage treatment is inaugurated while the sewage treatment is executed by one system of the reconstructed facility.  Finally, the substitutive treatment facility is disassembled and removed after three systems of the aged oxygen type aeration tanks OAT and the final settling basin F are reconstructed.
