Title: Driving method of noise at still reproducing
Inventor: YAMADA KOUICHI
IPC: G11B15/467
Filed: 1984-03-05
Abstract: PURPOSE:To drive the noise of a reproduced picture into both sides of a picture plane by transferring intermittently a magnetic tape until the center of a tracking error voltage obtained by processing a pilot signal enters into a set voltage range. CONSTITUTION:A tracking error signal is generated in accordance with the level difference of pilot signals reproduced as crosstalks from recording tracks adjacent to the front and back of a recording track to be reproduced and supplied to a terminal 31. A head switching signal H-SW synchronized with the rotational phase of a cylinder is inputted to a terminal 28 and a sampling pulse generated with a prescribed time delay by monostable multivibrator 29, 20 holds the tracking error signal. The holding voltage is detected by an absolute value detecting circuit 33 and a comparator 34 operates a pulse feeding circuit 36 until the holding voltage enters into the previously set up voltage range to transfer the magnetic tape intermittently. Thus, the noise can be driven into both the sides of the picture plane.

Title: Method for stably painting back surface of long metal plate in continuous painting
Inventor: MAKI NOBORU
IPC: B05D7/14
Filed: 1985-03-04
Abstract: PURPOSE:To perform back surface painting such that the effect of the vibration and lateral shaking of the thin metal mountings in a drying oven is not exerted on the back surface painting, by sucking a long metal plate after front and back surface painting by a suction apparatus to run the same in a curved state. CONSTITUTION:A long metal plate S is passed to a back surface painting roll 3 while closely contacted with the outer peripheral surface of a receiving roll 1 and run to the drying oven of a succeeding process. The metal plate S is run in a state closely contacted with the receiving roll 1 by a surface painting roll 2 and the shape thereof is corrected to well perform the coating of a paint. At the position of the back surface painting roll 3, the metal plate S is sucked and drawn down through a vacuum housing 5 by a fan 6 so as to increase the contact angle of said plate S in the direction of the back surface painting roll 3. By this method, the running shape of the metal plate S comes to a curve state and wavy wrinkles generated to the metal plate S are corrected by running tension.

IPC: H01J1/20
Filed: 1983-03-16
Abstract: PURPOSE:To enable a matrix cathode which is a unified construction including a barrier layer to be massproduced without widely changing the conventional manufacturing process by alternately applying a metallic powder and an electron-discharging matter powder over a heat-resisting thin metallic plate to make a layered construction, then compressing it to stick the plate and powders together, being followed by working the thus formed body into a cathode-like shape. CONSTITUTION:A metallic powder layer 2 principally consisting of Ni is formed on a heat-resisting thin metallic plate 1 working as a barrier layer by either application or spraying carried out with a spray gun. Next, an electron-discharging matter layer 3 composed of an oxide of an alkaline earth metal is formed on the layer 2. Following that, formation of the layers 2 and 3 are repeated to make a multilayer construction 4 which is then compressed or rolled with a pressing machine or a rolling machine to stick the layers 1, 2 and 3 together. The thus formed construction 4 is worked into a cathode-like pellet 5, thereby manufacturing a matrix cathode. Here, the thin plate 1 may consist of either a simple substance chosen from among Ni, W, Mo, Ta and Re or a thin alloy plate.

Abstract: PURPOSE:To increase the amplification factor hFE of effective p-n-p in an integrated implantation logic element (I<2>L) by forming an n type region for preventing the reverse implantation of holes to an n type epitaxial layer from the base of an inverter. CONSTITUTION:An n<+> type buried layer 6 is formed on a p type Si substrate 1, and an n type Si layer 2 is formed by epitaxial growth. B ions are implanted to form a p type region to become an injector, an n<+> type region 7 is formed by implanting P ions, B ions are implanted to form a p type region 4 to become the base of an n-p-n type inverter, As ions are implanted to form an n<+> type region 5. The impurity density of the region 7 is increased higher than that of the region 4 so that the implantation efficiency of the holes from the injector 3 to the layer 2 is good and the implantation efficiency of the holes from the base 4 is small, thereby preventing the decrease in the effective hFE of the p-n-p transistor.

Filed: 1993-03-03
Abstract: PURPOSE:To cope with various forming methods by one set of press by providing a continuously variable transmission cable of attaining an arbitrary sliding motion between a slide driving mechanism and a main motor. CONSTITUTION:The revolution of a main motor 18 is transmitted from a continuously variable transmission 8 to a slide drive mechanism 2, and a slide 3 is vertically driven by the slide drive mechanism 2. When the transmission gear ratio of the continuously variable transmission 8 is 1:1, since the rotational speed A' of a crank shaft 6 is constant, a slide motion becomes as shown in a curve A. Next, when performing a deep draw forming, etc., a slide motion shown in a curve B, is necessary. Accordingly, a crank shaft rotational speed shown in a curve B', is attained by sending an oil pressure to the hydraulic cylinder 13 of the continuously variable transmission 8 as the slide 3 starts to lower from the top dead center, and controlling the variable speed of the continuously variable transmission 8. Thus, a drawing, etc., can be performed by an optimum slide motion for a drawing.

The stator poles are disposed at an interval of 120 deg. with respect to the rotary shaft while keeping a constant gap with respect to the rotor. Since a space having no stator part can be produced over 120 deg. with respect to the rotary shaft, three stator poles can be disposed at same interval on the outer periphery of the rotor.

Filed: 1981-03-23
Abstract: PURPOSE:To exactly prevent burn-back and buckling of an electrode, by stopping a motor and electric power for welding interlockingly with each other when an output of an operating circuit has exceeded a reference value. CONSTITUTION:A comparator 15 subtracts an output of a reference setting device 16 from an output of an operating circuit 14, and outputs a signal when the output of the operating circuit 14 has exceeded the output of the reference setting device 16. The operating circuit 14 subtracts accelerating torque from generating torque of a motor, and obtains an output T. This signal T is compared with a reference value (r), and at the time T>r, the comparator 15 generates an output (a), therefore, when a set value (r) of the reference setting device 16 is decided so as to be equal to supplying torque of the normal time, containing dynamic friction torque, it can be detected with high accuracy that the motor has become an overload state due to occurrence of a fault in supplying power to a consumption electrode. The output of the comparator 15 is supplied to a motor controlling circuit 8 and an electric power source for welding 1, and supplying power to the consumption electrode and suppling the elecctric power for welding are stopped interlockingly with each other.
