Title: Protection circuit protected from overvoltage and overcurrent
Inventor: YOSHIOKA NARUO
IPC: H02H9/02
Filed: 1990-08-20
Abstract: A protection circuit is provided for protecting a semiconductor circuit or a communication line , e. g. a line for telephone and telecopier, a line for a cable television and a cable radio and the like, from a lightning surge as well as from continous overvoltage or overcurrent. The protection circuit comprises an electrical source connected to the equipment or circuit for supplying current to the equipment or circuit, a surge absorbing device arranged in parallel with the equipment or the circuit for absorbing a surge from said electrical source to the equipment or circuit, a positive thermistor having a high positive resistance temperature coefficient, arranged in series to the equipment or the circuit at a position between the electric source and the surge absorbing means, and a resistor connected in series to the semiconductor circuit or the line, at a position between the thermistor and the electric source. The current flowing through the protection circuit can be restricted without opening the circuit by melting a fuse. The electric current flowing through the microgap surge absorbing element can be suppressed by operating the positive thermistor so as to avoid overheating and firing of the circuit, thus providing both personnel and equipment protection. In addition, the protection circuit is passive except for the condition of overload when overvoltage and overcurrent exceed the fuse rating or the firing voltage rating of the surge absorbing element, therefore, it results in no need for calibration.

Abstract: The present invention relates to a method and means for treating pulp. In particular, it is suitable for treating fiber suspensions of the pulp and paper industry, and more specifically, it is related to the development of pulp mill screening plants, making their operation more effective and reducing their equipment requirements, thus enabling a considerable reduction in, for example, the investment costs. 
     As known, screening involves two problems. Firstly, after screening, it is usually desirable to increase the pulp consistency to a range of 10 to 15 % for storing or after-­treatment. Secondly, it is desirable to handle reject by either refining or some other method, but usually in a higher consistency than that of screening. In other words, the pulp flows always have to be thickened after screening. 
     The present invention comprises a method and means for screening pulp in a pressurized, closed space or spaces by means of screens in a consistency range of 1 to 5 % and by means of centrifugal cleaners in a consistency below 1 %, which method is characterized in that the various pulp screening and/or cleaning stages are effected in a pressurized state in a closed space in the screening plant and that access of air to the treated pulp is prevented by carrying out the thickening stages in a pressurized state, at the initial pressure of the preceding screening and/or cleaning stage.

Abstract: This invention provides an in situ monitoring technique and apparatus (20) for chemical/mechanical planarization end point detectionin the process of fabricating semiconductor or optical devices. Fabrication of semiconductor or optical devices often requires smooth planar surfaces, either on the surface of a wafer (2) being processed or at some intermediate stage e.g. a surface of an interleaved layer. The detection in the present invention is accomplished by means of capacitively measuring the thickness of a dielectric layer (4) on a conductive substrate. The measurement involves the dielectric layer (4), a flat electrode structure (25) and a liquid (20) interfacing the article and the electrode structure. Polishing slurry acts as the interfacing liquid. The electrode structure includes a measuring electrode (26), an insulator surrounding the measuring electrode (28,29), a guard electrode (27) and another insulator surrounding the guard electrode. In the measurement a drive voltage is supplied to the measuring electrode, and in a bootstrap arrangement to a surrounding guard electrode, thereby measuring the capacitance of the dielectric layer of interest without interfering effect from shunt leakage resistance. The process and apparatus are useful not only for measuring the thickness of dielectric layers on conductive substrates in situ, during planarizing polishing, but also for measuring the dielectric thickness on substrates in other processes, e.g. measuring the dielectric layer thickness prior to or after an etching process.

Abstract: An optical isolator comprises two birefringent plates one of which (29) separates two light components (c,d) whose planes of polarization are perpendicular to each other to make the two light components spatially separate between the two birefringent plates and pass through two separate optical paths and the other (30) of which thereafter combines the two separate light components, two Faraday rotators (31,32) disposed between the two birefringent plates and having a Faraday rotation angle of approximately 45 degrees, a polarizer (33) disposed between the two Faraday rotators and having a predetermined polarized-light transmitting angle, and a magnetic field device (34,35,36,37) for applying an external magnetic field to the two separate optical paths in the two Faraday rotators to magnetize respective regions near the two optical paths in each of the rotators in opposite magnetization directions to each other. In this arrangement two light components entering the polarizer in the forward direction has the same angle of plane of polarization as the predetermined polarized-light transmitting angle of the polarizer so as to pass through the polarizer, but two light components entering the polarizer in the reverse direction has an angle of plane of polarization perpendicular to the predetermined polarized-light transmitting angle of the polarizer so as not to pass through the polarizer. The high performance polarization-independent optical isolator may be obtained with high isolation of more than 50 dB, which is easy in assembling or manufacturing.

Abstract: An interleaver (34) processes information in a pseudorandom order to provide pseudorandom interleaved data for communication to a deinterleaver (42). The pseudorandom interleaved data is processed at the deinterleaver (42) in a pseudorandom order corresponding to that used at the interleaver (34) means, to recover the original information. The pseudorandom processing at the deinterleaver is synchronized with the pseudorandom processing at the interleaver on a trial and error basis. In one embodiment, full synchronization occurs when a Viterbi decoder (44) receiving data from the deinterleaver has a renormalization rate within a designated threshold and when enough synchronization words are detected in data output from the deinterleaver to meet a predetermined criterion. In another embodiment, a timer is used to initiate a new starting address for the pseudorandom processing at the deinterleaver during successive time intervals. Synchronization is achieved when a start address is found that results in the detection of enough synchronization words in data output from the deinterleaver to meet a predetermined synchronization criterion.
