Title: Dry etching apparatus
Inventor: NAKAMURA MORITAKA
IPC: H01L21/302
Filed: 1986-06-20
Abstract: PURPOSE:To obtain a sheet dry etching apparatus which can process at a high speed by directing downward the surface of a cooling stage which forms a cathode for fixedly holding a substrate to be processed through an electrostatic chuck to prevent the substrate cooling effect from reducing to improve the substrate cooling efficiency. CONSTITUTION:A cooling stage 12 which becomes a cathode 112, and one or a plurality of gas injecting holes 14 which penetrate an electrostatic chuck 13 arranged in contact with the lower surface of the stage are provided, nitrogen, helium or gas, such as CF4, SF6 used for etching is injected in a short time from the holes 14 to separate a substrate S to be processed from the surface of the chuck 13 by the gas pressure. Accordingly, since foreign materials such as dusts dropped from the wall of an etching chamber are not dropped to be adhered to the substrate attracting surface of the chuck, the substrate and the attracting surface of the chuck are always contacted uniformly. Thus, the heat conductivity from the substrate to the chuck is improved stably.

Abstract: PROBLEM TO BE SOLVED: To ease a work during inspection of a factory or during a service work by a method wherein a water storage tank is provided with a high water level detecting device and a low water level detecting device and a time between detection of the high water level detecting device and detection of the low water level detecting device is measured and displayed. SOLUTION: In order to detect a water quantity consumption time, namely, a time in which a low water level switch is turned ON after a high water level switch is turned ON, it is judged at S1 whether the high water level switch is turned ON. When the high water level switch is turned ON, a water feed valve is brought into an OFFstate at S4 and measurement of a timer is started at S5. Consecutively, it is judged at S6 whether the low water level switch is turned ON, namely, whether a low water level is detected. When a low water level is detected and an ice storage process or fixed time drainage is not effected at S7, a timer count time is displayed at S8. This constitution displays ice making capacity at a display means and grasps it even when container, a weight meter, and a clock are not available and improves workability of an operation work and a service work.

Title: Reflective periodic branching filter
Inventor: WATANABE TAKAICHI
IPC: H01P1/213
Filed: 1978-11-28
Abstract: PURPOSE:To secure the sharper rise for the amplitude characteristics by inserting the reflective  periodic delay circuits featuring the equal delay characteristics to each other into the two paths branched off by the coupler. CONSTITUTION:The reflective periodic branching filter consists of polarized wave separator 6,  coupler 7, circular polarized wave generators 8 and 8', periodic delay circuits 9 and 9' plus metal reflector plates 5 and 5' each. When the electromagmetic wave containing the vertical polarized  wave including the signal channels of frequencies f1, f2... is put in through terminal 1, the electromagnetic wave transmitted and converted into the horizontal polarized wave through separator  6 is divided equally into two parts through coupler 7 to be then converted into the circular polarized wave through generators 8 and 8'. The electromagnetic waves branched off to paths 3 and 4  are reflected by plates 5 and 5' after passing through circuits 9 and 9' featuring the same delay  characteristics. Thus the phase receives the staircase-type change, and characteristics 10 and 11 of  the phase variation at paths 3 and 4 feature an integer-fold phase difference of pi via the five frequencies between resonance points 13. As a result, the band featuring the same or opposite  phase is expanded when the electromagnetic waves of paths 3 and 4 are compounded via coupler  7, thus ensuring an extremely sharp rise for the amplitude characteristics.

Title: Protective circuit for supepconducting device
Inventor: OHARA AKINORI
IPC: H02H7/00
Filed: 1986-06-24
Abstract: PURPOSE:To unnecessitate the lead wire to be provided on a normal temperature part by a method wherein all the component parts of the protective circuit to be used for a superconducting device are provided within a cryogenic temperature. CONSTITUTION:When a superconducting switch 2 is quenched, voltage is generated at both ends of the switch. The voltage generated at both ends of the switch 2 in the beginning of the quenching is feeble. Also, the voltage same as above is applied to the primary winding 10a of the transformer 10 connected to the switch 2 in parallel. On the other hand, the number of turns of the secondary winding 10b of the transformer 10 is larger than that of the winding 10, and as a result, amplified voltage is applied to the winding 10b. When a quenching is generated on the switch 2, a thyristor 6 is brought in a conductive state, and the switch 2 is protected by allowing a circulating current to pass. Also, a constant voltage diode 11 is controlled so as to prevent the application of excessive voltage on the thyristor 6.

Title: Labeling processor
Inventor: KOBAYASHI YOSHIKI
IPC: G06T7/60
Filed: 1985-07-05
Abstract: PURPOSE:To attain the high-speed labeling process suited to the real time processing of the ITV camera pictures by using a label separation detecting part to detect and store the separation of the labels sent from a label generating part. CONSTITUTION:The picture data 8 read out of an ITV camera in the raster scan direction is binary-coded by a picture segmenting part 100. Then a local area including 2 vertical picture elements and 3 horizontal picture elements is segmented. In a joint mode of the tentative labeling, just a single writing operation is applied to a label relation table LRT 700 with MAX.MIN of picture elements near the local area. Thus a label conversion table LTT 800 which is integrated to the final label is produced from the LRT information. A label separation detecting part 900 detects and stores the separation of labels in the labeling state where the label conversion is carried out based on the table LTT 800. Thus the separated labels are detected and corrected and therefore it is enough to write the MIN label to the MAX table address of the table LRT just by a single time.
