Filed: 1985-10-14
Abstract: PURPOSE:To accurately measure internal water content, by forming two holes to the surface of a molded body composed of concrete or mortar and inserting electrodes in respective holes up to a desired depth. CONSTITUTION:At first, holes 4, 4' each having a relatively small diameter are respectively formed at two proper areas at a predetermined interval (d) so as to be inwardly extend in almost parallel to each other. Next, electrodes 5 are respectively arranged in said holes 4, 4'. One end of a lead wire 6 is fixed to one flat surface of each electrode 5 and the other end thereof is inserted in each of the holes 4, 4' from one end of a tubular electrode insert jig 7 to be protruded to the outside from the other end of said jig 7 and the upper surface of the electrode 5 is contacted with one end 8 of the jig 7. Thus contacted electrode 5 is applied to the inlet of the hole 4 or 3' and the other end 10 of the jig 7 is struck by a tool 12 to drive the electrode 5 into a desired depth. When the electrode 5 has been driven into the desired depth, the jig 7 is pulled off from the hole to arrange the electrode 5 at a desired position. By this method, the electrodes 5 are respectively arranged in the holes 4, 4' and connected to an electric resistance type moisture meter to measure the water content in concrete 1.

IPC: G05F1/613
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To obtain a DC/DC converter which can deal satisfactorily with a large current when the large current flows, by a method wherein a voltage at a primary-side input terminal is detected, and a current at the input terminal is bypassed when the voltage at the input terminal becomes a prescribed value or higher. SOLUTION: A DC/DC converter turns on and off a switching transistor 6 on the primary side of a transformer 8 so as to obtain an output voltage on the secondary side. At this time, when a pulse-shaped inrush current or the like is inputted as an input current as a constant current flowing across an input terminal 1 and an input terminal 2, also an input voltage across the input terminals 1, 2 is changed accoridng to the current. When the input voltage exceeds a prescribed value due to a change in the current, the voltage which exceeds the prescribed value is detected by a voltage detection circuit 4. On the bases of its detection output, a part of the current across the input terminals 1, 2 is bypassed by a bypass circuit 3. As a result, when a large current flows, it is possible to deal satisfactorily with the large current.

Title: Discharge method for lithium secondary battery
Inventor: ARAKAWA MASAYASU
IPC: H01M10/05
Filed: 1993-08-23
Abstract: PURPOSE:To prevent deteriorating a battery characteristic and worsening thermal stability due to repeated charge/discharge by performing the prescribed initial discharge at the time of ending the charge or starting the discharge, in a lithium secondary battery using a lithium metal for its negative pole. CONSTITUTION:At the time of ending a charge or starting a discharge of a battery, the initial discharge within 30 seconds is performed by current density of 5mA/cm<2> or more per unit area of a positive or negative pole. A uniform fine hole is opened to a protective film formed in a lithium surface by the discharge of large current thus performed, and in the case of low current discharge thereafter, lithium is uniformly fused to remove the protective film. Thus by preventing producing needle-shaped lithium due to local deposition in the case of charge thereafter, a charge/discharge life and thermal stability are improved. Further by increasing current density of the initial discharge, a discharge time can be shortened.

Abstract: PURPOSE:To easily and quickly perform the returning of an index to a pre scribed reference position, by changing the index being displayed on a display picture to a value representing a relative position for the reference position of the index when a prescribed indication means is operated. CONSTITUTION:The titled device is equipped with a memory means 51 which stores the relative position for the reference position of the index, an instructing means 53 which supplies instruction to return the index to a standard unit, and a control means 55 which changes the relative position of the index stored in the memory means 51 to the reference position according to the instruction from the instruction means 53, and returns the index to the reference position. It is assumed that (0, 0) is set as the coordinate value of a set reference position 21 of the index 20 on the display picture. When a mouse operation is performed, a CPU detects an operated quantity, and performs the arithmetic calculation of an absolute coordinate value (x1, y1) for the set reference position 21, and moved the index 20 to a position of (x2, y1). When an operation to return the index 20 to the set reference position 21 is performed in operating, the CPU resets a current absolute coordinate value (xn, yn), and changes it to (0, 0). In this way, the index 20 is returned to the set reference position 21.
