Abstract: PURPOSE:To indicate works to both of a preceding process and a succeeding PROCESS without producing the excessive stock in process in a inter-process buffer by securing syn-chronism even when the number of works as one work object of the preceding process and that of the succeeding process are not equal. CONSTITUTION:Calculating means 11 and 12 for stock in process and between processes calculte the quantity of parts or products in a line and that of parts in the inter-process buffer. A work indication suppression/suppressin release discriminating means 13 compares the standard stock quantity of each aritcle stored in a storage device 4 with the calculated stock in-process quantity to decide suppression of work indications to lines or release of suppressed work indications and suppressed work indications or releases suppression of work indications through a work indication suppressing means 14 and a work indication suppression release means 15. A standard stock proper quantity calculating means 16 calculates the standard stockquantity as the reference of suppression/ suppression release of work indications with respect to each article and keeps the stock quantity between processes in a certain level or lower.

Title: Feed-water controller
Inventor: SATOU MOTOYUKI
IPC: F22D5/26
Filed: 1978-03-31
Abstract: PURPOSE: To safely operate a feed water pump in a voltage transformation shape, by automatically changing over the control of said pump and adjusting valves by automatically discriminating the modes of a safety operation range and a critical speed range when feeding water by means of the feed water pump that the safety operation speed range is limited.  
     CONSTITUTION: When a command signal of the speed of revolution becomes not more than limit value, a first feedwater adjusting valve 61 is operated in the circumferential direction by means of a feedwater adjusting valve control portion 15 while a second feedwater adjusting valve 62 interlocked with said valve 61 is perfectly closed. If the capacity of the adjusting valve 61 is selected not less than a flow rate discharged from a feed water pump 4 in the speed limit at that time, the variation of a feed water flow rate due to the opening and closing of the adjusting valve 62 approximately becomes extinct. When the command signal of the speed of revolution is not more than limit value, the speed of the revolution of a feedwater turbine becomes constant, and the adjusting valve 61 is controlled. When the signal returns not less than limit value, the adjusting valves 61, 62 are perfectly opened and shifts to the control of the speed of the pump, and smoothly changed over.

Filed: 1981-03-18
Abstract: PURPOSE:To monitor the cavitation in a reducing valve by calculating a cavitation coefficient on the basis of water pressure values measured on respective sides of upper stream and downstream of the reducing valve for giving the alarm when the coefficient is under a fixed value. CONSTITUTION:A valve upper stream side water pressure detection pipe 5 is fixed on the upper stream side of a reducing valve 3, while a valve downstream side water pressure detection pipe 6 is fixed on the downstream side.

Abstract: PURPOSE:To make it possible to set independently threshold points at which input and output gains are changed over, by providing a 2nd signal current source connected to a 1st signal current source with an input-output terminal. CONSTITUTION:The emitter of transistor TRQ1, i.e., a 1st signal current source with an input-output terminal, is connected to power supply Vcc via resistance R1, and its collector is grounded via resistance R2 and 2nd signal current source I01. Then, the emitter of TRQ2 is connected to the connection point between resistance R2 and current source I01, its collector is connected to power supply Vcc, and its base is applied with voltage VB. In the formation of this circuit, the threshold point at the input side is determined by current I01 and that on the output side depends upon current I01 and voltage VB. The input and output threshold values can therefore be set to desired values independently.

Title: Message recording system
Inventor: OMORI TAKAYUKI
IPC: H04M1/64
Filed: 1990-02-20
Abstract: PURPOSE:To improve the convenience for use of a telephone set with the message recording function by permitting incoming to the telephone set to record the message of an originating subscriber without closing a DC loop circuit to a subscriber regardless of the off-hook state at the time when the state that the message recording function can be operated is set. CONSTITUTION:When a hook switch 12 is set to the off-hook state, a DC loop closing function 100 closes the DC loop circuit to a subscriber line, and a message recording function 200 records the message of an absence incoming call. When the state that the message recording function 200 can be operated is set, a cut-off means 300 stops the start of the DC loop closing function 100 due to the hook switch 12. Consequently, the DC loop circuit to the subscriber line 2 is not closed regardless of the hook-off state when the state that the message recording function 200 can be operated is set, and therefore, incoming to the telephone set is permitted and the message of the originating subscriber can be recorded. Thus, the convenience for use of the telephone set with the message recording function is improved.
