Title: Dynamic gas flow controller
Inventor: MICHAEL E WILLMER
IPC: G05D7/00
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To send a gas flow out with high precision over a wide dynamic range by comparing a signal indicating a desired amount of discharged gas calculated by integrating a desired inflow input signal and a signal indicating the actual amount of gas discharged from a reservoir and generating a calibration signal while a reservoir exit isolation valve is open. SOLUTION: The gas flow from the reservoir 350 to a process chamber 366 is metered by a variable flow rate control valve 356 controlled by a self- calibration type dynamic flow rate control circuit 301. Here, while the reservoir exit isolation valve 352 is open, the desired flow input signal is integrated to calculate desired mass discharged from the reservoir 350. Further, the mass of the gas in the reservoir 350 before the exit isolation valve 352 is opened is compared with the mass of the gas in the reservoir 350 when the exit isolation valve 351 is closed to calculate the actual mass of the gas discharged from the reservoir 350. Then the signal indicating the desired discharge mass is compared with the signal indicating the actual mass to generate an updated calibration signal.

Title: Control device for plural hydraulic pump
Inventor: HIRATA TOICHI
IPC: F04B49/00
Filed: 1987-06-12
Abstract: PURPOSE:To improve pump efficiency by providing a flow rate distributing means which detects hydraulic pressure supplied by a group of hydraulic pumps to compute a necessary flow rate, and sets each hydraulic pump in order to its fixed maximum delivery rate according to the computed necessary flow rate. CONSTITUTION:A hydraulic pressure detector 14 detects delivery hydraulic pressure supplied by hydraulic pumps 2a, 2b, and a control part 16 computes a necessary flow rate on the detected delivery hydraulic pressure. When the computed necessary flow rate is below the maximum delivery flow rate fixed to the hydraulic pump 2a, the hydraulic pump 2a bears the computed necessary flow rate for itself, and when it is above the above-mentioned maximum delivery flow rate, the hydraulic pump 2b functions to bear its excess flow rate. Thus the whole pump efficiency can be improved to achieve energy saving.

Filed: 1985-07-04
Abstract: PURPOSE:To improve the communication efficiency by providing a transmission range designating means to designate the transmission range of the original, a read address calculating means, and a line address designating means and attaining the partial transmission of an original. CONSTITUTION:The transmission range designating means 7 is an inputted means by which an operator designates which part of the original is to be transmitted. Said input information is outputted to the read address calculating means 8. The means 8 calculates the read start line address and the read end line address of a picture signal accumulating means 4, and outputs the line address information. A control circuit 1, using the information from the means 8, sets the read address of the means 4 in the line address designating means 9, reads picture signals from the position where the means 4 is designated, and outputs them to a communication controlling means 6 via a picture signal encoding means 5. Then the circuit 1 modifies the line address of the means 9, and the outputting is continued until the next line address of the means 4 coincides with the read end line address. In such way, the partial transmission of the original is made possible, and the communication efficiency is improved.

Filed: 1981-09-18
Abstract: PURPOSE:To decrease the general resistance of electrodes, by using the electrodes in which molybdenum or tungsten conductive layers are coated with polysilicon. CONSTITUTION:A silicon wafer 11 is subjected to thermal oxidation to form an oxidized  film 12 having several humdreds Angstrom thickness. A nitrided silicon layer 13 having several hundreds Angstrom  thickness is formed by a chemical vapor phase growing method. Then, molybdenum or tungsten is vapor-deposited thereon to form a conductive film, and the molybdenum or tungsten other than electrodes 14, 15 is removed by a photoetching method. Afterward, polysilicon having several hundreds Angstrom  thickness is formed by the chemical vapor phase growing method, and boron or phosphorus ion implanation  is performed for this polysilicon to decrease the electric resistance, and polysilicon electrodes 16, 17 are formed by a photoetching method. Finally, a moisture sensitive material 20 is coated to prepare a moisture sensor. Since the electrode resistance of the moisture sensor constituted in such a way is decreased by <=2 digits as compared with that of an electrode formed only with polysilicon and the resistance of the moisture sensitive material is lowered, it is possible to lower noises from the outside and the influence due to leakage resistance.
