Title: Hot wire welding equipment
Inventor: HORI KATSUYOSHI
IPC: B23K9/073
Filed: 1992-09-08
Abstract: PURPOSE:To prevent an arc current from flowing in the wire power source side by putting a switching element of large capacity into the secondary side of a wire heating power source and turning the switching element on for a pulse energized period of time of an added wire. CONSTITUTION:The pulse output current waveform and a current value of the wire heating power source 16 are controlled by primary side switching transistors 12a and 12b. The primary side switching transistors 12a' and 12b and a switching transistor 17 connected to the secondary side are made in an off state in an unenergized period of time of a pulse current and besides, these transistors are controlled so that these are also made in the off state when the added wire 6 is separated from base metals 1 by utilizing a signal, etc., from a touch detection circuit 10. Consequently, since the path where the arc current flows in the wire heating power source is cut off by the switching transistor 17 even when the tip of the wire 6 is in arc plasma 5, an arc 5b is not generated between a tungsten electrode 2 and the added wire 6.

Title: Method for developing nonsilver salt photosensitive material
Inventor: NAKANO MIEJI
IPC: G03F7/30
Filed: 1987-09-24
Abstract: PURPOSE:To stabilize development processing by using a small amount of developing solution by regulating an angle of immersing the photosensitive material into the repeatedly used developing solution to <=30 deg.. CONSTITUTION:The immersion angle theta2 of the photosensitive material into the repeatedly used developing solution is regulated to <=30 deg. to the horizontal line. If theta2 is >30 deg., the rear end of the photosensitive material kicks up the feeding member 7 of the developing solution and sometimes impairs it, when the end passes by the member 7, and the film of the developing solution at the end becomes thin, and the film is repelled, resulting in poor development. If theta2 is too small, the immersion of the photosensitive material into the developing solution becomes impossible, and it is preferred to select an angle of enabling the immersion, and the range of 4 deg.-10 deg. is optimum, thus permitting development uniformity to be enhanced by using a small amount of developing solution.

Abstract: PURPOSE:To constitute the title device so that a vertical stripe moves in the horizontal direction and becomes invisible in the case of an interlace display by constituting said device by constituting picture elements of the same color component so as to be arranged in the vertical direction between picture element trains in the horizontal direction corresponding to every field. CONSTITUTION:Between picture element trains in the horizontal direction corresponding to each field for constituting one image, picture elements of the same color component are arranged so as to be arranged in the vertical direction without being shifted in the horizontal direction. When an interlace display is executed with respect to such a picture element array, when for instance, a display of R (oblique line part) is taken notice of, in a first field, write is executed in the upper one line of two lines as shown in (a) and displayed, and in a display of a second field, a part where a first field is moved as it is to the lower part by a one--picture element portion as shown in (b) is displayed. Accordingly, when the display of each field for constituting one image is switched, the picture elements of the same color component moves only in the vertical direction. In such a way, it does not occur that the vertical stripe is viewed so as to flow in the horizontal direction, and a stable screen having a high resolution is obtained.

Title: Electrophotographic device
Inventor: YASUBA HIROSHI
IPC: G03G15/20
Filed: 1987-09-28
Abstract: PURPOSE:To prevent defective fixing from being generated and to prevent a copying operation from being interrupted by extending a copying time when the temperature of a heating roll in a fixing device drops less than a constant temperature, and preventing the temperature of the heating roll from being lowered. CONSTITUTION:A first fixing time at a waiting time and a second fixing time for securing fixing in the copying operation are stored in a central control unit 31. Assuming a copying interval between the copy of a k-th sheet and that of a (k+1)th sheet as Sk, the copying interval Sk is set as Sk=Sk+1 while the temperature of the heating roll stays between the first fixing time and the second fixing time in case of performing continuous copying, and when it drops less than the second fixing time, the copying interval Sk is set as Sk<S+1. Thus, by decreasing copying speed, it is possible to prevent the defective fixing from being generated, which enables the continuous copying to be performed.
