Patent JP-S5861410-A (JP)
Title: Induction type flowmeter
Inventor: KAYAMA NAGAOKI
IPC: G01F1/56
Filed: 1981-10-07
Abstract: PURPOSE:To eliminate errors in measurement even when the properties of measuring fluid vary  by using various quantities such as electrostatic capacity in accordance with the dielectric  constant when either one of an electric field or a magnetic field is made zero as references  and determining the flow rate and flow speed from the ratios of change with respect to said  reference quantities. CONSTITUTION:A switch SW1 is provided between electrodes 9a, 9b for application of electric  fields and a DC power source 12 and turns electric fields on and off as its opening and closing are controlled by the timing signal from a timing signal generator 13. Two capacitors CA, CB  are charged alternately through a switch SW2 of which the two contacts C, (d) repeat on and  off alternately in synchronization with the switch SW1 for on and off of electric fields. Therefore, the voltage proportional to the electrostatic capacity C in the stage of measurement appears in the capacitor CA and the voltage proportional to the electrostatic capacity Co corresponding to the zero flow speed appears in the capacitor CB because the electric fields are  made zero. Both voltages are differentially amplified by a differential amplifier 23 and are inputted to a voltage-duty cycle conversion circuit 24. The final output 22 of the duty cycle  proportional to (C-Co)/Co is obtained. Since the same electrostatic capacity as that at zero  flow speed is obtained in an off state by turning the electric field on and off in such a way,  the speed and rate of flow are measured accurately under continuity of flow.

IPC: H01S3/042
Filed: 1991-07-02
Abstract: PURPOSE:To shorten preliminary operation time by switching the flow rate of pure water flowing in a flow route, in two stages of specified ratio of pump discharge. CONSTITUTION:The flow rate of water 9 flowing through the first flow route 14 arranged in a parallel system route 18 is Q1. The flow rate of water 9 flowing through the flow route system 18 is Q2. The ratio Q1/Q2 is set as two stages of 0% and 75%. A flow rate control means for controlling the above ratio is constituted of four valves 21, 22, 24, 25. When first operation 26a is applied to a signal generator 27, and a pump 19 is operated, the total amount of water of pump discharge flows through a water demineralizing apparatus 15. Hence in a cooling equipment 29, purity of the demineralized water 9 can be improved in a short time. When second operation 26b is applied to the signal generator 27 after purity of water 9 is increased in the cooling equipment 29, the valve 24 is wholly opened and the valve 25 is wholly closed. Since the water 9 of high insulation resistance flows through a reflecting mirror chamber 4, it is possible that a high voltage for ignition is immediately applied to a lamp 3, and a laser oscillator 1 is made to start laser oscillation operation.

IPC: H01L21/00
Filed: 1989-06-26
Abstract: PURPOSE: To avoid increasing the process time by determining actual output values from measuring parameters by a process model calculation at a pre- selected time and ending the process when the actual output values equal to nominal values. CONSTITUTION: A process control computer 5 computes actual output values from measured parameter values at pre-selected time by a process model computation. The parameters are the temp. of temp. sensors 6 and gas flow rates measured by flow-meters 10, 11. The computer 5 computes e.g. every second the actual output values from the measured parameter values, compares these output values with nominal values and ends an oxidation process when the output values agree with the nominal ones. As the result, the nominal values are obtained even with interference of control programs. Thus, the increase of the process time is avoided.

Title: Method and device for guiding passing-sheet in leveler
Inventor: TARUI MASAAKI
IPC: B21D1/05
Filed: 1984-07-31
Abstract: PURPOSE:To prevent a metallic strip from meandering and to pass the strip smoothly by moving >=1 pair of upper and lower rolls, used for holding the strip between them in its thickness direction, in the sheet-width direction. CONSTITUTION:A passing-sheet guiding device 2 is installed on the upstream side of a leveler 1, and a meander sensor 3 and an arithmetic control unit 4 are provided to the same side. The device 2 is formed by providing upper and lower guide rolls 15, 12 to a moving frame 6 capable of moving in the width direction of a metallic strip (s). In case of leveling the shape of strip (s) by the leveler 1, the frame 6 is moved to a required position in conformity with the sheet (s) width to hole both ends, in the width direction of strip (s), between the rolls 12, 15. Then the rolls 12, 15 are rotated through gears 11, 14 by driving a motor 16, to force the strip (s) to pass through the leveler 1. When the meandering of strip (s) is generated, the sensor 3 outputs a signal to the unit 4 to compute the meandering quantity by the unit 4, which outputs a command signal to move the frame 6 to the sheet-width direction. The rolls 12, 15 are moved in the sheet-width direction while holding the strip (s) between them, to correct the meandering of strip (s).

Title: Grafting robot
Inventor: OTSUKI HARUKI
IPC: A01G1/06
Filed: 1992-06-19
Abstract: PURPOSE:To provide a grafting robot having excellent workability and provided with a compact scion-holding part. CONSTITUTION:A scion seeding to be placed on a scion supplying plate 14 can easily be held without contacting with other parts by extending a transfer arm 79. In the above process, the scion is stably held by using a hand (composed of a cotyledon-pressing hand 81, a hycopotyl-holding hand 83 and a root-fixing hand 84) to hold at least two parts of the scion. The swing of the root part is prevented and the transfer speed can be increased by supporting the hycopotyl at two points in transfer. The scion cotyledon hand composed of a pair of hands has an opening 96 for supporting the developing base of cotyledon with a notched part on the hycopotyl-contacting face. Since the hycopotyl is not directly held with the opening 96, the pressing of hycopotyl and the damage of seedling can be prevented. The hycopotyl hand 83 simply suspends the developing base of the cotyledon of the scion and, accordingly, the vertical thickness of the hand 83 can be reduced to shorten the length of the hycopotyl.
