Title: Level sensor
Inventor: OTA NAOKI
IPC: G01F23/28
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To obtain a level sensor which can detect a level in a plurality of places by a method wherein a plurality of light-emitting-side optical-fiber radiant ends and a plurality of light-receiving-side optical-fiber incident ends are arranged on the outer surface of a tubular case along its axial direction in a prism part which is extended to the axial direction at the inside of the tubular case. SOLUTION: A prism part 1A at the inside of a tubular case 1 is formed in such a way that two faces are crossed at right angles and that their crossed ridge line is parallel with the axis of the tubular case 1. A light-emitting-side optical-fiber radiant end 2A and a light- receiving-side optical-fiber incident end 2B are installed on the outer surface of the tubular case 1 along its axial direction. When a liquid is not filled into the tubular case 1, light from the radiant end 2A is totally reflected by the prism part 1A due to the refractive index of the tubular case 1 and that of the air, and it forms an optical path L so as to be incident on the incident end 2B. When a liquid is filled into the tubular case 1, light from the radiant end 2A is refracted to a direction (m) due to the refractive index of the tubular case 1 and that of the liquid, and it is not incident on the incident side 2B. Consequently, when radiant ends 2A and incident ends 2B are installed in a plurality of places so as to investigate whether light is incident on the incident ends 2B or not, the liquid level can be measured at each place.

Title: Controller
Inventor: MIYABE ASAO
IPC: G05B13/02
Filed: 1986-06-20
Abstract: PURPOSE:To set an automatic control state in a short time at the time of start-up by using a start-up processing means. CONSTITUTION:A controller works based on pseudo set value signal outputted in steps from a set value changing part and releases a start-up mode when the process value shows a desirable transient answer to set an automatic control operation mode. In other words, a set value changing part 21 of a start-up processing means 2 outputs the pseudo set value signal SVD which changes in steps by a prescribed amount S1 in a range smaller than that of the set value signal SV. A PI control means 3 outputs the operating signal MV to a process 1 and therefore the process 1 is controlled by the signal MV. Then the process value PV is outputted in accordance with the characteristics of the process 1. An adaptive control processing part 4 observes a transient answer and calculates the PI arithmetic constant of the means 3 to obtain the desirable damping value and the desirable overshoot value. Thus the PI arithmetic constant is set and changed.

CONSTITUTION:A gas is made to flow through a hollow glass tube 15 having a tapered part 17 at the tip and a slit or hole 18 near the tip opening in the direction of arrows 16 and 16''. The gas is then made to offset the inflow of a combustion gas 5 from a burner 1 (arrow 5'') and flow out of the hole 18 in the direction of arrows 16' and 16''. After collision of the gas flow from the burner 1 with the growing end of a porous glass base material 2, the gas flows along the tapered part 17 in the direction of arrow 5' and is discharged in the direction of arrow 14. The growing end of the base material 2 is placed at a distance l0 from the bottom of the part 17 to deposite fine particles of glass, and a starting part 4 is moved in the direction of arrow 7 while rotated in the direction of arrow 8. Thus, a porous glass base material having almost uniform outside diameter and bulk density can be stably prepared to give an optical fiber having uniform band characteristics.

At the same time, the analog waveforms are compared by a comparator 17 with a specific analog reference level and the comparison result is inputted as a section signal preferentially to the digital values to classify the parts between the through holes 7 into plural groups. Then a CPU 8 measures a drawing-out equivalent quantity roughly according to the section signal while following up the drawing-out speed of the tape 5 and also measures the tape from the digital values with high resolution, so that the arithmetic result is displayed 4.

Filed: 1988-06-14
Abstract: PURPOSE:To manufacture a coil composed of an oxide superconductor efficiently and comparatively easily by ejecting superfines as the raw material of the oxide superconductor from a fine nozzle against the circumferential surface of a cylindrical base material heated and rotated and moved in a vacuum vessel and forming the coil. CONSTITUTION:A cylindrical base material 4 of a cylinder rotatably mounted in a vacuum vessel 1 is heated to >=200 deg.C, the inside of the vacuum vessel 1 is evacuated, and the superfines of yttrium, copper or barium are ejected together with a carrier gas consisting of an inert gas or the mixed gas of the inert gas and oxygen gas from a fine nozzle 7 set up toward the surface of the base material 4.

Abstract: PURPOSE:To improve power source utilization and image quality, by a method wherein a heating element for one row is split into a plurality of pieces, and a heat-sensitive head is so placed that the pitch of the rows becomes an integer times of dot pitch. CONSTITUTION:The heating resistors 19, 20 split into M rows are provided on the heat-sensitive recording heat at a pitch of N times or (N+1/M) times (N is an integer) of the recording dot pitch P.

Title: Changing system for setting of digital protective relay
Inventor: MIYATA MITSUFUMI
IPC: H02H3/02
Filed: 1993-06-16
Abstract: PURPOSE:To prevent a digital protective relay from operating at an erroneously inputted new setting value at the time of changing the setting of the relay. CONSTITUTION:When it is confirmed in Step 20 that the setting of a digital protective relay is being done from the presence/absence of inputs to the setting operating section of the relay, the process proceeds to Steps 22 and 24. The presence/absence of the inputted new setting value and, when the input is made, whether or not the new value falls within an inputting range are checked and, when the new value is out of the range, it is indicated that the inputted value is abnormal and the process returns to Step 22. When the inputted value falls within the range, the process proceeds to an AC input comparing section 40. The present AC input value is compared with the new setting value and when a discriminating condition 'AC input value >= new setting value' is 'Yes', the relay operates with the new setting value. Therefore, the information is indicated by flickering the operation displaying section of the relay so as to give the operator warning. After warning, the process returns to Step 22. When the condition is 'No', the process proceeds to the next step and, when 'process is completed' is selected, a setting change completing process is started and, thereafter, the relay is operated at the new setting value.
