With the knurled surface disposed upside, the workpiece is sandwiched between the upper foil 6 and a lower foil 5, a sandwich structure 3 is grasped between grasping units 7 and 8 to clamp both the ends. Then, a knob 18 is operated, and an interval between a chariot 13 and a base member is increased, and the structure 3 is elongated. An upward force is added to a lower side of the structure 3 to bend the workpiece, the foil 6 is removed, individual bars are removed from the foil 5 for later treatment. Thus, at the time of cutting a plate-like material such as, for example, a semiconductor wafer, the sectional surfaces are brought into contact with each other to prevent an accident to damage it.

Abstract: PURPOSE:To safely and efficiently obtain a germicidal water having high germicidal power in low concentration with minimal additive quantities of chemicals by adding hypochlorite to water in an anode chamber, adding acids, such as hydrochloric acid, to water in a cathode chamber, performing electrolysis so that the pH value in the anode chamber and the pH value in the cathode chamber are regulated to values in practically specific ranges, respectively, and then mixing the resulting waters. CONSTITUTION:Hypochlorite is added to water in an anode chamber 3' of an electrolytic cell 1 and acid, such as hydrochloric acid, is added to water in a cathode chamber 2', and electrolysis is performed so that pH value of the water, as electrolytic product, in the anode chamber 3' and the pH value of the water, as electrolytic product, in the cathode chamber 2' are regulated to about 3-9 and 4-7, respectively, and the resulting electrolytic water in the anode chamber 3' and electrolytic water in the cathode chamber are joined and mixed and formed into germicidal water containing hypochlorous acid where pH is regulated to about 3-7. Because the electrolytic water neutralized to pH4-7 in the cathode chamber 2' is mixed with the electrolytic water containing hypochlorous acid of pH3-9 formed in the anode chamber 3', the germicidal water containing hypochlorous acid having high germicidal power in low concentration can be obtained without generating chlorine gas. This method is safe and efficient.

Title: Partial discharge measurement method
Inventor: TSUNODA YOSHIO
IPC: G01R31/12
Filed: 1992-07-17
Abstract: PURPOSE:To calibrate electric charge properly and measure partial discharge accurately by using a relatively high frequency where the impedance characteristics of a power cable converge. CONSTITUTION:A detection impedance Zd is connected to an insulation connection part Sa of a power cable S. Also, a pulse generator G is connected to the connection part Sa via a capacitor C. The cable S is pulse-wise divided into two parts by the impedance Zd and impedances at both sides of the connection part Sa are expressed by impedances Z1 and Z2, respectively. When calibrating electric charge of the cable S, a known amount of electric charge is supplied from the generator S. In this case, the impedance Zd becomes constant when the partial discharge is performed using a frequency which is 2kHz or higher where impedance characteristics are converged, thus performing calibration properly without being affected by the reflection within the cable S on calibration.

Abstract: PURPOSE:To make it possible to assure the prescribed flow rate of a fluid even in case of malfunction of the movable part of a valve caused by freezing thereof in the valve used for the electronic fuel injection system of a vehicle etc. CONSTITUTION:Normally, a port 19b is connected to a port 19a via the passage 43 of a movable member 30 and a gap between a valve body 41 and a seat 42, and since the movable member 30 energized by a spring 40 follows the movement of a movable core 15 in the right direction, the gap between the valve body 41 and the seat 42 is gradually narrowed down, and said port 19b is closed when the valve body 41 makes contact with the seat 42. When a movable core 15 is further shifted in the right direction, the rubber valve part 32 of a disc valve 31 separates from the movable member 30 to permit the ports 19a, 19b to be communicated with each other. It is possible with the constitution described above to assure a prescribed flow rate via the passage 43 even if the movable part such as the disc valve 31 and/or the movable member 30 if frozen.

Title: Inputting device for sewing pattern data of sewing machine
Inventor: YAMADA KAZUNORI
IPC: D05B19/10
Filed: 1989-08-19
Abstract: PURPOSE:To prepare data of needle drop points along an inputted sewing pattern by inputting respective necessary coordinate points in a lump with one time of function selection even in a complicated sewing pattern. CONSTITUTION:Groups of input points stored in a memory 22 are grouped by dividing them according to the guide of corner designating points to take out the data in the group unit. Whether the pattern formed of the input point group in the group is a straight line or curve is judged according to whether the number of input points belonging to the group is '1' or at least '2'. When the number of input points is '1', it means the straight line, and when at least '2', the curve. The coordinate values of respective needle drop points are calculated with a seam length set by straight line or curve interpolation in each group, and the data of respective calculated needle drop points are stored sequentially in a memory 22. A prepared sewing pattern is used after the completion of the process of all input pints so that automatic sewing is carried out according to the inputted pattern similarly to the conventional sewing. Thus, the data of needle drop points on a desired sewing pattern are calculated so that the sewing pattern data can be automatically prepared.
