IPC: H01L21/265
Filed: 1982-05-21
Abstract: PURPOSE:To prevent a malfunction while a sample is being supplied by shifting the location of a timing detector required for the supply of the sample from the surface of the sample. CONSTITUTION:When a timing detector 15 is set to P1, it detects a branch plates 3 (width c) first and then a sample 4 (width d) since the same sample 4 passes through.

IPC: G05B13/02
Filed: 1989-04-05
Abstract: PURPOSE:To obtain an evaluation index without being influenced by the response time of process output by setting waveform observation time on the basis of the generation time of first deviation. CONSTITUTION:The auto-tuning function 8 of a PID controller 2 consists of a waveform observation instruction function 3, an index calculation function 4 and a control parameter correction function 6. The waveform observation instruction function 3 takes in a deviation (e) between a target value SV and a controlled variable PV at every sampling period, and when its absolute value becomes over a prescribed value e1, it issues a waveform observation start instruction to the index calculation function 4. Next, time required for the absolute value of the deviation (e) becomes below the prescribed value e2 is obtained, and it is made waveform observation base time tb. Then, waveform observation time Rt is calculated by multiplying tb by three. Then, when the time Rt elapses, a waveform observation finish instruction is issued to the index calculation function 4. The index calculation function 4 observes waveform from the waveform observation start instruction to the finish instruction, and calculates the evaluation index according to a given formula, and a control parameter is corrected according to this.

Title: Method and device for controlling clear rate flow in atm network
Inventor: BUCKLEY CLIFFORD JAMES
IPC: H04Q3/00
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To more timely and correctly calculate the resource allocation of a usable bit rate virtual circuit(VC) by updating the state of a VC to which a cell arrives to active state by a switch when the cell arrives at the switch, or incrementing the number of active VC just for '1' when the state is inactive and continuously performing series of processing. SOLUTION: Assuming that the VC is set in an inactive state 302 first, when the cell arrives at the switch, the switch updates the VC state to an active state 304. When the VC state is instructed as a test state 306 and the cell arrives, the state is similarly updates active 304. After the elapse of prescribed time interval, the VC confirmed active is changed into a test state and the VC confirmed as the test state is set to the inactive state. When the VC is changed from the test state to the inactive state, the counted number of active VC during proceedings is incremented just by '1'.

Title: Metal fine particle-supported hydrocarbon modifying catalyst and its production
Inventor: IIDA KOZO
IPC: B01J23/54
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To control the deposition of carbon on a catalyst and to attempt the high activity and long life of the catalyst in a modification reaction for modifying hydrocarbons with water vapor and carbon dioxide by making catalyst components ooze out from the inside to the surface. SOLUTION: Hydrotalcite is used as a precursor, and a catalyst in which Mg and A1 are replaced partially or totally with a noble metal or a transition metal is obtained. In the baking stage in this process, the noble metal and the transition metal, which are active metals, ooze out from the inside to the surface to make the catalyst with highly dispersed metal particles supported. The catalyst is obtained which is especially effective for modifying hydrocarbons with water vapor and CO2 , for example, the CO2 reforming reaction of methane, the partial oxidation reaction of methane, a methanation reaction for synthesizing methane from CO and H2 , the production of synthetic gas by the modification or decomposition reaction of methanol. The variation with the passage of time in the CH4 and CO2 conversion percentages of the catalyst is exhibited.  Every developed catalyst indicates stable, high generation.
