Title: Method of controlling thyristor rectifier device of dc arc furnace
Inventor: KASUGA TOSHIAKI
IPC: H05B7/148
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To reduce gradually a short circuit current even when short circuit occurs between electrodes by correcting a firing angle of a thyristor with a corrected value of the firing angle equivalent to an increase rate value when an increase rate per unit time of an electrode current exceeds a specified value. SOLUTION: An increase rate computing element 41 is used to compute an increase rate per unit time ΔI from an electrode current. A corrected value arithmetic operation circuit 42 specifies a firing angle corrected value to be zero within the range of the increase rate ΔI from zero up to ΔI1 and increases the firing angle corrected value from ΔI1 to ΔI2 . When ΔI is larger than ΔI2 , an arithmetic operation is made where the firing angle corrected value is used. Furthermore, the firing corrected value is added to a firing angle command value by means of an adding computing element 43. When the increase rate ΔI exceeds a predetermined value of a setting apparatus 45, a timer 46 is started by a comparator 44, which outputs a holding command.  In other words, a holding circuit 47 is arranged to hold an immediately preceding value of the adding computing element 43. This value is output to a firing angle controller 48, thereby controlling a thyristor rectifier device.

Title: Coupling member
Inventor: TAKAHASHI KAZUNARI
IPC: B43K21/00
Filed: 1994-08-31
Abstract: PURPOSE: To attach a coupling member easily to a cylindrical member even when there is certain dispersion in the dimensions of a product by a method in which a groove part is formed between couplers of two cylindrical parts, a frame part which is bonded to the groove part is formed on the cylindrical member, and the groove width of the groove part is made a little larger than the thickness of the frame part. CONSTITUTION: The groove width M of a groove part 16 which is constituted by a frame part 10 which is formed on a coupling member 6 and bonding projections 12, 13 is formed to be a little larger than the thickness T of an inner frame part 1a which is formed on the front end surface of a shaft cylinder 1. Accordingly, a gap S is formed between the tip of the inner frame part 1a and the front end surface of the groove part 16. The gap S is made to be the largest value of the dispersion in the dimensions of a product. In this way, the coupling member can be attached easily to the shaft cylinder 1 even when there is certain dimensional dispersion in the groove width of the groove part 16 or the thickness of the inner frame part 1a of the shaft cylinder 1.

Title: Forming method of semiconductor element isolation layer
Inventor: GI ZAE FU
IPC: H01L21/316
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To prevent an active layer from nonuniformly decreasing, by forming a second material layer of a side wall only on the side surface of the long axis direction both ends of a first material layer, and executing a field oxidizing process by using the first and the second layers as masks. SOLUTION: On the whole surface containing a nitride layer 44 to be patterned, another nitride layer composed of the same part member is again spread, and a nitride side wall 47 is formed on the side surface of the nitride layer 44 by etching back. Patterning is so performed that only the photoresist 45 of a part corresponding to the almost central part of an active region is selectively eliminated, and a nitride side wall 47 on the exposed active region in the short axis direction is eliminated by dry etching. The photoresist 45 for using as a mask is eliminated, and a field oxide film for using as an element isolation layer is formed. In this case, bird's beaks permeate from various directions, especially in the both end portions in the long axis direction, and the active region is narrowed.  The side wall formed in the portions restricts the permeation of the bird's beaks, and almost the same width as the part where the side wall does not exist can be obtained.

Abstract: PROBLEM TO BE SOLVED: To prevent the undesired printing by trouble light and to improve image quality by disposing a light shielding member having a pinhole allowing the passage of a laser beam past a window between a semiconductor laser and a collimator lens. SOLUTION: The light shielding member 44 includes a disk-shaped main body 46 consisting of plastic, etc., and is formed with the pinhole 48 in the central part of this main body 46. When current is imparted to the semiconductor laser 36, the laser beam of an elliptic cross section is emitted from its end face. This laser beam is applied through the window 28, the pinhole 48 and a lens barrel to the collimator lens and is converted to parallel luminous fluxes by the collimator lens. The greater part of the laser beam spreading to a prescribed angle or above from the optical axis A of the semiconductor laser 36 and the laser beam reflected at the inside surface of the window 28 disposed at a case 30 do not pass the pinhole 48 of the light shielding member 44. The greater part of the laser beam reflected at the inside surface of the pinhole 48 is attenuated by reflection.  Then, the generation of the trouble light which is the cause for the undesired printing is averted.

A peak detector 10 detects the amplitude of a sum signal outputted from the adder 9 while a prob position detector 11 detects the position of the probe 4. An equiphase position detector 12 determines the position at which an amplitude distribution reaches its maximum in a maximum position detector 14. Then, an arithmetic processing/display device 15 receives the input of a signal of the resulting maximum position, an ultrasonic frequency from an input unit 16 and the like to calculate and display the position of the defect 2.
