Inventor: SUZUKI YASUO
IPC: B23H7/02
Filed: 1985-06-12
Abstract: PURPOSE:To prevent breaking of wire electrode without sacrifice of machining speed by reducing the arc discharge energy upon continuation of such condition as the detected average machining current is higher than predetermined level under concentrated discharge condition more than predetermined time. CONSTITUTION:Entire discharge machining current is detected through current detector 22 then amplified through an amplifier 23 and removed of high frequency components through filter circuit 24 to be fed as average machining current to comparator/amplifier 25. Upon exceeding of the average current over the setting level in setter 26, the output is brought to logical '0' which is fed to the input end of OR gate 21. Upon flowing of average machining current higher than predetermined level to sustain discharge at fixed position, the output of gate 21 is brought to logical '0' thus to release reset condition of counter 28. Consequently, the counter 28 will control the circuit such that the signal is brought to logical '1' upon reaching of clock having predetermined frequency to be produced from oscillator 27 to predetermined count and fed to the circuits 10, 11 thus to shorten ON-time of machining pulse or to lengthen OFF time.

Abstract: PURPOSE:To improve the heat resistance of a substrate for a solar battery, to shorten pore sealing time or to delete pore sealing step by setting the pore sealability of an anodic oxidation alumina of the substrate made of aluminum/ anodic oxidation alumina film to 40% or less. CONSTITUTION:An anodic oxidation alumina film 2 of 40% or less of pore sealability sealed in pressurized steam of 4 atm is formed by subjecting an aluminum plate 1 of 99.99% of purity with 0.3mm thick to an anodic oxidation in an oxalic acid bath to insulate the surface of the plate. The first electrode 3 is formed of a thin metal film made of metal such as stainless steel, chromium or titanium. 4 is an a-Si layer, and formed of a P-type layer, an I-type layer and an N-type layer. The second electrode 5 is of light transmission, and formed of a thin In2O3 film containing 5wt% of SnO2. Since the pore sealability of the alumina film is set to 40% or less, the film can sufficiently endure the accumulating temperature of the a-Si solar battery having heat resistance of 300 deg.C or higher.

Filed: 1985-06-11
Abstract: PURPOSE:To know the actual working time of a transaction facility which performs the transaction of totalization of notes, etc., by counting the processing time for each unit transaction totalize the unit transaction time. CONSTITUTION:When the sorting/counting operation of cash is through together with the manual input of broken notes and the input of securities, an operator pushes an end key. Then a control part 8 compares the amount written on a slip with the amount of transaction and stores the notes in a store box when coincidence is obtained between both amounts. Here the part 8 totalizes the transaction amounts and stores them in a totalization storage area and an account storage area of a memory part 9. Then the part 8 defines the time of a timepiece device 10 as a transaction end time point to store it in a time storage area in a RAM 11 and calculates the time needed for the transaction from the start time and the end time stored in the RAM 11. Thus the part 8 totalizes calculated transaction time (consumed time) and stores it in the account corresponding to the account storage area of the part 9 as well as in the total storage area. Thus it is possible to know the actual working time of a transaction machine.

IPC: H01M10/39
Filed: 1984-06-20
Abstract: PURPOSE:To eliminate influence of temperature increase to an adjacent battery caused by breakage by arranging a mechanism by which supply of sodium is stopped when a solid electrolyte tube is broken, sodium directly reacts with sulfur, and temperature is increased, and connecting a battery to an adjacent battery by a connector which is directly installed in the battery. CONSTITUTION:The bottom of a sodium reservoir 11 is welded to the upper end of a metal tube 10. An anode pipe 12 for exhausting and sodium filling, which is vacuum-sealed after sodium filling, is welded to the upper part of the sodium reservoir 11. An anode terminal 13 is welded to the outer lower side of the sodium reservoir 11. A filler 17 which is resistant to molten sodium is filled in a space formed by the inside of an inner insertion tube 20 and the outside of the metal tube 10. If a solid electrode tube is broken, direct reaction of sodium with sulfur is eased by the filler 17. When temperature is increased by continued reaction, a copper or aluminum rod 14 inserted inside the metal tube 10 is melted and blocks a passage of sodium to stop the supply of sodium.

Title: Method and device for measuring resistivity of fine particles
Inventor: MAKABE AKIRA
IPC: G01R27/02
Filed: 1990-05-18
Abstract: PURPOSE:To compare volume resistivity between fine particles samples by measuring bulk density (percentage of void) and the volume resistivity simultaneously. CONSTITUTION:The fine particle 23 to be measured is packed in the recessed part 24 of a lower cell 22, and after the surface of it is smoothed, an upper cell 21 on which a weight 30 is placed is placed, and the thickness (d) of a fine particle layer after the lapse of prescribed time is measured with a digital micrometer or a non-contact displacement gage until the change of the bulk density is stopped, and the bulk density rhob is calculated. Also, the weight (m) of the fine particle 23 packed in the recessed part 24 of the lower cell 22 is decided in advance. The bulk density rhob is found in equation rhob=m/(s+d). When particle density is known, the percentage (epsilon) of void can be found in equation epsilon=1-(rho6/rhob). Therefore, it is possible to find the volume resistivity by applying a voltage V to the upper cell 21 simultaneously with the measurement of the bulk density and reading a current value (i) with an ammeter 29. In other words, it is possible to compare and study the volume resistivity between the samples by setting the bulk density as a medium.
