Title: Method for controlling knitting needle in knitting machine and apparatus therefor
Inventor: TAKEGAWA YUJIRO
IPC: D04B15/00
Filed: 1994-10-27
Abstract: PURPOSE: To minimize unfavorable effects of knitting caused by an overshoot by controlling the needle speed at least just before the speed change point so as to keep the extent of the overshoot of the knitting needles constant. CONSTITUTION: The speeds of plural needles are set with a setter so as to keep the extent of overshoot for a knitting speed in a knitting machine of the type in which the plural needles are moved by a linear motor type needle motor. The optimal needle speed corresponding to the knitting speed is selected through a processing circuit to output a driving signal to a driver and the knitting needles are moved to promote the knitting. The extent of the overshoot is sensed during the knitting to compare the sensed value with the preset target value.  The needle speeds at least just before the speed change point are controlled so that the compared value may be zero or a constant value or may be a tolerance of the extent of the overshoot when the compared value exceeds a prescribed value or the knitting speeds may be regulated in the case of a different needle movement pattern in one course by discriminating whether the needle movement pattern differs in the one course.

Title: Arrester fault indicator
Inventor: SHIMOMURA TETSURO
IPC: H02H7/24
Filed: 1989-11-01
Abstract: PURPOSE:To surely indicate a fault by connecting an electrical gap in series with an arrester and operating a fault indicating mechanism by a current flowing through a circuit comprising an inductance element, connected in parallel with the gap, and the inductance element. CONSTITUTION:When an arrester 5 functions on a surge voltage such as a lightning impulse, impedance of a reactor 23 increases because of the quite high frequency of the surge voltage and a high voltage is applied across a gap 21 thus causing flashover thereof. Consequently, lightning current flows from a casing 20 through the gap 21 to the arrester 5. When an inner fault occurs in the arrester 5 and an AC fault current having commercial frequency flows continuously, impedance of the reactor 23 lowers considerably thus lowering the voltage to be applied across the gap 21. Consequently, insulation is maintained and AC fault current flows through a circuit of the reactor 23 and a fusible wire 32.

Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To achieve the high speed reading operation and the high speed verification and simplify the control of the reference voltage generation by a method wherein a number of values are judged by using a plurality of reference voltages simultaneously and reference voltages for verification are set by using the judged results. SOLUTION: Quaternary data which are judged by three different thresholds (Vra, Vrb and Vrc) are stored in a memory cell 11. In an ordinary reading operation, reference signal generators 14a-14c output reference signals Vra-Vrc. Stored datum signals read out of the memory cell 11 are compared with the reference signals Vra-Vrc and judgement signals are supplied to an encoder 15. The encoder 15 outputs a four-value code, for instance '10' in accordance with the threshold region in which the stored datum signal exists and the four- value code is latched by a latching circuit 16. A controller 18 controls the reference voltage generators 14a-14c and makes them output reference signals VraH, VrbL and Vrc.

Title: Manufacture of device
Inventor: KARII JIYOO HANSON
IPC: H05K3/06
Filed: 1994-10-28
Abstract: PURPOSE: To control etching speed by making a reaction product formed by reaction between titanium and etching solution component form a thin film on a titanium surface and reducing the etching speed of titanium. CONSTITUTION: An etching solution is an aqueous solution that contains a propylene glycol of 30 vol.%, an ammonium fluoride of 2.7 M and an HF of 1.9 mol. At first, titanium is etched at a rapid active etching speed 10, which quickly lowers to a controllable etching speed 20 as etching proceeds. The etching solution is a composition that contains ions from a salt which forms a complex with oxidized titanium, and when the concentration of the complex becomes close to its solubility limit, the complex sediments and forms a thin film on the titanium surface. Such thin film changes the etching speed from the rapid active etching speed 10 to the moderate controllable speed 20. The solubility limit of the complex to the etching solution depends on the composition of the etching solution. Therefore, etching speed can be controlled.

Abstract: PURPOSE:To perform necessary minimum edge cutting amount of a semiconductor device by obtaining the edge cut by photoetching. CONSTITUTION:After the entire surface of a wafer 1 is coated thinly with a photoresist 2, a light beam L is emitted through a photomask 7 having a light beam absorbing black pattern 8 at a position corresponding to a periphery to be cut at its edge of the wafer 1 to transfer the pattern 8 onto the photoresist 2. Thereafter, the portion that the beam L is not emitted nor cured is removed by a solvent to obtain the edge cut. Thus, the edge cutting amount is decided in response to the shape of the pattern 8, the edge cutting amount d3 of an orientation flat portion 6 can be equalized to that of other periphery by suitably setting the shape of the pattern 8. Since solvent is not sprayed, no pinhole due to the spraying can be produced.
