    Abstract: The invention is a cellulose derivative wherein some of the carboxyl groups of the cellulose derivative carboxymethylcellulose are replaced with —CO—NH—X—CO—Y—Z, and a hydrogel of the same. In the formula, X is a C1-10 divalent hydrocarbon group, Y is a divalent group derived from polyalkylene oxide having oxygen atoms at both ends, and Z is a C1-24 hydrocarbon group or —CO—R4, where R4 is a C1-23 hydrocarbon group. The hydrogel has excellent viscoelasticity and can be injected into prescribed sites with injecting devices such as syringes, and it can thus be utilized as a medical gel or adhesion barrier.

    Abstract: An in-vehicle apparatus, used in a vehicle having a speed limit release mode, is configured to stop sending trouble occurrence information to an information collection center when the speed limit release mode is being turned on. Stopping of the information sending allows a hard disk drive in the in-vehicle apparatus not to have an access thereto, thereby decreasing possibility of hard disk related problems in the vehicle.

    Abstract: A wire electric discharge machining method capable of improving a machining accuracy of a corner portion. A machining feed speed is gradually reduced from a point A before entering a corner portion machining between points C and D, and in the corner portion between points C and D the machining is performed at a fixed feed speed. The feed speed is gradually increased from the point D, where the machining of the corner portion is completed, and is restored to the original speed. In accordance with the change of the feed speed, an off-state time of the voltage applied between a wire and a workpiece is increased from a point B and is reduced from a point E after completing the corner portion machining, to restore the original off-state time at a point F. Further, a flow rate of machining fluid is reduced depending on the corner portion. The feed speed, the off-state time and the flow rate of the machining fluid are controlled by automatically changing them in dependence on a curvature of the corner portion. A warp of the wire electrode is substantially prevented at the beginning of and during the corner portion machining, to thereby improve the machining accuracy of the corner portion.

    Abstract: A wire disconnection position detecting apparatus of a wire feed path in which wire disconnection is caused and the causes of the disconnection in this section set in advance. Upon disconnection of a wire, as a voltage for disconnection position detection applied to the wire through a conductor is detected by a microprocessor through an electrode disposed on the lower-course side of the conductor (S3), the value in a register for rewinding amount storage is updated, with rewind of the wire by a rewinding motor, in accordance with pulses delivered from a rotary encoder (S4, S5), and thereafter, the rotation of the motor and the application of the voltage are stopped when a cut end of the wire passes the electrode (S6 to S8). Based on the result of comparison between a detected rewinding amount and the distances between the electrode and individual parts arranged along the wire feed path, the microprocessor detects the section of the wire feed path in which the wire is snapped (S9), and displays the wire disconnection section and the causes of the disconnection in this section, in the form of messages, on a CRT screen (S10).

    Abstract: A wire discharge machining power source controls an average machining voltage value applied between a wire electrode (P) and a workpiece (W) to be zero to prevent galvanic corrosion of the workpiece (W). A reverse voltage application time control circuit (2) detects the average machining voltage value and generates a pulse (S5) having a pulse width corresponding to a detected value. A reverse voltage regulating circuit (1) detects a difference between a reference voltage and a voltage applied between a transistor (T2) and a resistor (R2) upon application of the reverse voltage through the transistor (T2) and the resistor (R2), and supplies a difference signal, which corresponds to the detected difference, as an ON control signal to the transistor (T2) for a period corresponding to the width of the pulse (S5), thereby controlling the reverse voltage value and setting the average machining voltage value to zero.
