Title: Reflection type variable resistance attenuator
Inventor: YODA YOUICHIROU
IPC: H03G1/00
Filed: 1988-05-23
Abstract: PURPOSE:To obtain sufficient attenuation quantity even in a high-frequency area by distributingly connecting one electrode of a PIN diode to input and output terminals separately provided for a package. CONSTITUTION:Since one electrode of a PIN diode 2 is distributingly connected to respective input and output terminals 3 and 4 separately provided in a reflection type variable resistance attenuator, the attenuation quantity is determined by the ratio of the impedance of the PIN diode 2 to change according to a bias current to the impedance of bonding wires 5 and 6 connected to input and output ports 7 and 8. Consequently, the impedance ratio can be larger even in the high-frequency area, and the sufficient attenuation quantity can be obtained.

IPC: B41F13/04
Filed: 1983-07-06
Abstract: PURPOSE:To eliminate a plate cylinder for each printing length by a method wherein a peripheral length of a plate cylinder is made longer than the maximum printing length and a sheet is moved back and forth so as to make advancing length and retreating length from the finish of the printing to the start of the next printing coincide. CONSTITUTION:A peripheral length L of a plate cylinder 22 and a printing length LO are set in a setter 40. Sheet lengths between adjacent printing parts 141-14n are integral multiples of LO. The plate cylinder 22 is rotated with a peripheral speed VB to make sheets 10 run with a speed LO/L.VB. By controlling a control motor 29, the speed is made identical to the peripheral speed VB from a printing starting point T12 to a printing finishing point T12 and, from the printing finishing point T12 to the next printing starting point T21, the speed is reduced and once reversed and then accelerated again and made coincide with the peripheral speed VB at the printing starting point T21 to make the movement zero. By repeating such control, the sheets 10, on which multicolor printing is applied, are continuously discharged from pulling rollers 17.

Title: Controlling returned sludge
Inventor: YOKOYAMA TAKESHI
IPC: C02F3/12
Filed: 1978-10-12
Abstract: PURPOSE: To compensate time delay of settlement quantity variations in the sludge collecting hopper, due to sludge settling time in the final sedimentation tank, the quantity of mixed liquid charged from the aeration tank is corrected in response to the quantity of sewage that flows in, and the flow rate of return sludge is controlled.  
     CONSTITUTION: The detector 13 for the quantity of sewage that flows in detects the change in the flow rate of sewage 5 that flows into the aeration tank 1. Meanwhile, the detector 14 for the quantity of returned sludge detects the quantity of sludge 11 returned to the aeration tank 1. The quantity of returned sludge 11 is determined by calculation of the return-sludge calculator and controller 15 using the quantity of flowing-in sewage 5 and other data. The determined quantity is used to correct the charge of mixed solution 6 from the aeration tank 1 to the final sedimentation tank 2. This means when the flow-in sewage is increasing, the sludge charge to the aeration tank 1 is increased in advance, and when decreasing, the sludge decreased. Thus, the process eliminates a deffective control in the quantity of returned sludge due to shortage or surplus in sludge collected in the final sedimentation tank.

Title: Data collection system
Inventor: SAITOU SATORU
IPC: G07G1/14
Filed: 1982-07-16
Abstract: PURPOSE:To prevent the duplicated transmission of data, by inhibiting data from being fetched from a terminal equipment when a counted value that a CPU receives from the terminal equipment coincides with the counted value of its own coungint means. CONSTITUTION:The CPU1 sends a polling signal to an electronic cash register ECR2. In response to this polling signal, the ECR2 transmits Z (clearing) reckoning data and the counted value of a counter 25a to the CPU1. The CPU1 compares the received counted value with the counted value of its counter 15a and when the both do not coincide with each other, the received Z reckoning data is stored in a Z reckoning data collection area 15b. Then, a clear command is transmitted to the ECR2. In this case, the counter 25a is not updated unless the Z reckoning data in the ECR2 is cleared in response to the clear command because of, for example, an error of transmission. Therefore, the counted values of the counters 15a and 25a coincide with each other. When this coincidence is judged, the fetch of the Z reckoning data is inhibited.
