Abstract: PURPOSE:To appropriately control the discharge of condensed water, restrain a level from being abruptly changed, and thereby prevent a control valve from being frequently opened/closed by counting the time required for the water level of condensed water tank to reach a specified level while being out of a definite range, and thereby adjusting the opening of the control valve based on the result of the time counted. CONSTITUTION:In the steam using equipment, a water level sensor 5 detecting the water level of a condensed water tank 1 is provided for the condensed water tank 1 having an inflow port 2 through which condensed water and steam flow in, and a discharge port 3 discharging condensed water, and meanwhile, a control valve 4 controlling the discharge of condensed water is provided for the discharge port 3. A water level signal from the water level sensor 5 is inputted to a control section 6 wherein the time is counted, which is required for the level of a water level signal to reach a specified level while being out of a definite range determined based on a reference range. Abrupt change in a water level is thereby restrained by adjusting the opening of the control valve 4 in such a way that a water level is returned to its reference range based on the destination time counted and a specified level.

Title: Method for preventing erroneous transmission of facsimile equipment
Inventor: MURATA TSUNEO
IPC: H04N1/32
Filed: 1982-07-30
Abstract: PURPOSE:To insert originals for discrimination which classify plural originals to be transmitted piled up on an original placing plate for every addressed facsimile equipment and detect these originals for discrimination, so that erroneous transmission is prevented thereafter. CONSTITUTION:When originals P are piled up on an original placing plate 1 and a microswitch 15 is turned on, a control section 30 starts feeding. In this case, if the microswitch remains as turned on even after the paper feeding of a prescribed length is made, it is judged that the originals which are to be fed are originals to be transmitted and the originals P are fed to a point D (read scanning position), and then, the transmission operation is started. When the first original to be transmitted has been transmitted, the main control section 30 detects a completed signal through the output signal (k) of a counter 20 and adds one to the value of the counter 20. When an original for discrimination is fed after a prescribed sheets of originals are transmitted in such way, the microswitch 15 is turned off and a signal (f) becomes ''0'' level. The control section 30 detects this and compares the value of the internal counter at the time with preset data of the number of originals to be transmitted, and judges whether the transmission to the addressed facsimile equipment has been normally performed or not.
