Abstract: PURPOSE:To prevent a undercut and to increase a welding efficiency by approaching one unit of welding power source and plural electrode wires from a feeding mechanism to a base metal in high current density and at high speed and by changing a main arc between electrode wires. CONSTITUTION:Plural electrode wires 11, 12 are connected to the one unit of welding electric source 10 having dropping characteristic to feed the wires 11, 12 simultaneously by one unit of a driving source. The wire 11, 12 are approached for a base metal 14 with a wire feeding mechanism 13 and a big current is passed from the power source 10 as well, then, a main arc is generated on the near electrode wire 11 of one part first, the welding current is concentrated on the wire 11 and a pool 16 is formed. The main arc is moved to the wire 12 with the wire 11 becoming short, thereafter the movement of the main arc is repeated. The welding efficiency is increased and undercut can be prevented because of the arc length becoming short and current density being raised.

Abstract: PROBLEM TO BE SOLVED: To realize excellent image formation without irregular pitch, etc., even when operation is shifted to normal image forming operation immediately after detecting the density of a patch image by eliminating influence by a discharge product adhering to the sleeve surface of a developing means at the time of patch image forming operation. SOLUTION: At the time of forming the patch image, a developing device 4k on the most downstream side in the rotating direction of a photo-receptor drum 1 is moved to a developing position so as to develop a patch latent image on the drum 1, and the density of the patch image is measured by a sensor 13 and recorded as an initial value. While restoring the device 4k to a home position, developing bias is made off, and a sleeve is stopped, then the image forming operation of a developing device 4m on more upstream side than the device 4k by one is performed in the same procedure. Thus, ozone, etc., from an electrifier 2 carried on the flow of air caused by the rotation of the drum 1 is dammed by the rotating sleeve 44 of the device 4m and prevented from adhering to the surface of the sleeve of the device 4k.  The image forming operation of developing devices 4c and 4y on the upstream side is performed in the same manner successively, and the rotation of the drum 1 is stopped.

IPC: H03L7/14
Filed: 1987-08-05
Abstract: PURPOSE:To execute a PLL operation whose follow-up property to a pilot signal is satisfactory, by providing a loop filter of a PLL circuit by dividing it into two of a wide band and a narrow band, limiting the output voltage width as for the wide band loop filter, and allowing only the narrow band loop filter to have a holding function of an output voltage. CONSTITUTION:A drift until a holding circuit 7 operates after a pilot signal has been cut off instantaneously remains within a limited range of the output voltage width of a wide band loop filter 4. That is, by taking more widely the lead-in width of a PLL circuit by the wide band loop filter 4 only, than the variation width of an output frequency of a VCO 2 corresponding to the limited width of an output voltage, a drift of the output frequency of the VCO 2 until the holding circuit 7 operates after the pilot signal is cut off instantaneously can be held within the lead-in width of the wide band loop filter 4. Accordingly, lead-in can be executed quickly at the time of reinput of the pilot signal. Also, this circuit si constituted so that the lock range width is taken charge of by a narrow band loop filter 6, and the high speed property is taken charge of by the wide band loop filter 4. In such a way, a PLL operation whose follow-up property to the pilot signal is satisfactory can be executed.

Title: Coater
Inventor: ARUFURETSUDO ERUNSUTO BOSAADO
IPC: G03F7/16
Filed: 1984-09-17
Abstract: A pouring head is arranged above a conveyer belt which carries objects to be coated with a coating material being poured from the pouring head in the form of a curtain extending transversely to the direction of travel of the belt. In order to limit the free falling curtain on both sides two rim severing organs are provided on each side of the curtain, one organ above the other, as well as curtain edge-guiding means, one for each severing organ, which are arranged each adjacent the severing organ to which it pertains. The lower severing organs are arranged a short distance above the conveyer belt. The two severing organs comprise blades for cutting off marginal strips from the falling curtain in two successive stages, thus reducing the width of the curtain to a desired size. The lower severing organ serves mainly to cut off the rim bead being conventionally produced on the curtain where it slides downward on the curtain guiding means, thus preventing the occurrence of undesirably thick marginal zones in the coatings produced on the objects being moved underneath the pouring head by the conveyer belt.

Filed: 1987-08-05
Abstract: PURPOSE:To cut torque transmission, work effectively ABS and improve the durability of a power transmitter in a four-wheel drive car provided with ABS by releasing a second friction clutch from engagement in braking. CONSTITUTION:When ABS works in quick braking of a vehicle, torque transmitted to front and rear wheels needs to be cut. Then, a second friction clutch 7 is released from engagement, i.e. when oil sent from a hydraulic device is changed over to discharge pressurized oil from a cylinder chamber 75, contact pressure of respective frictional plates 61, 63 is released and only preload due to an elastic member 73 remains. Also, then, a first friction clutch 5 is not turned on since the internal pressure of a viscous coupling is not increased. As a result, power from an inner hub 11 of input shaft is not transmitted to the output shaft 27 side, and ABS works effectively to prevent four wheels from simultaneous locking in quick braking or the like.

Abstract: PURPOSE:To reduce the vertical smear by extracting the light charge containing the vertical smear, etc. and the charge containing the vertical smear only after separating them from each other and carrying out the subtraction between both charges. CONSTITUTION:A pair of horizontal CCD(10,10'') are used to transfer an electric charge during a repetition mode of one of electrode pairs. In this case, horizontal switch transistors 81...8n and 8'1...8'n are used for two switching actions respectively.
