Title: Rotary drum device for magnetic recording and reproducing device
Inventor: UMEHARA HIROSHI
IPC: G11B5/53
Filed: 1991-02-13
Abstract: PURPOSE:To reduce a disturbance of picture at the time of special reproduction by providing four magnetic heads on a rotary drum to respectively record/ reproduce on four tracks and making the azimuth of each magnetic head to be respectively different. CONSTITUTION:Two pairs of magnetic heads 22, 23 and 24, 25 adjacent each other are arranged on the rotary drum 21 to record or reproduce by dividing one screen part of a TV signal into four tracks A1-D1, etc., on a magnetic tape 26. The azimuth of magnetic heads 22-25 are set to +theta1, -theta1, +theta2, -theta2 respectively. By this constitution, when the reproduction is made by the head 2 obliquely crossing each track along the arrow G at the time of special reproduction such as a research reproduction, etc., by a fast feeding or rewinding, the parts 30a-30c are reproduced since the azimuth of head 22 and tracks A3, A2, A1 coincide. Consequently, only the signal of corresponding track can be reproduced by each magnetic head, and the disturbance of picture at the special reproduction time is reduced.

Filed: 1986-02-03
Abstract: PURPOSE:To constitute the titled device so that a display of each part of a picture can be read distinctly in the same way, even in case of a large-sized liquid crystal display device, especially, whose size in the upper and lower directions is long, by applying a high voltage and a low voltage to a part whose visual angle is small, and a part whose visual angle is large, respectively. CONSTITUTION:When no voltage is applied in the upper and lower substrate surfaces, in case of a TN type liquid crystal display device in which liquid crystal molecule orienting directions are orthogonal, when an applied voltage is made high, an angle thetabecomes smaller, and when the applied voltage is made low, the angle theta becomes larger. As a matter of fact, in case when a visual angle is large, a threshold voltage by which a display part comes to be seen darkly becomes lower, and in case the visual angle is small, the voltage by which the display part is seen darkly becomes higher. In each part of the display picture, a difference of how a display image is seen goes to a problem, in case a size in the upper and lower directions of the display device is large, generally, the visual angle is large in the upper part of the display device, and the visual angle is small in the lower part. In such a way, when the angle thetais made to coincide with or approach a visual angle phi as much as possible,m in accordance with a variation of the visual angle phi in each part of the liquid crystal display element, the liquid crystal display comes to be seen distinctly.

Abstract: PURPOSE:To conduct practically the IC connection and switch for MIST, by making selection between an enhancement type and a depression type by the existence or nonexistence of the implanted impurities to the channel part of the MISTr. CONSTITUTION:The drain of the MISTrTre on the side of the load is connected to the power source, which is connected to the gate and again connected to the drain of the MISTrTrd on the side of the driving, and the source is earthed. At the formation of such a logical circuit, when the pattern of ion implantation mask is changed to the first logical circuit wherein the Tre on the side of the load is made to depression type while the Trd on the side of the driving is made to the enhancement type, the circuit becomes the normal invertor circuit. On the other hand, when the reverse change is made to form the second logical circuit wherein the Tre on the side of the load is made to enhancement type while the Trd on the side of the driving is made to depression type, the Tre is always open while the Trd is always closed. Therefore signals of low level can be obtained at the output terminal Out regardless of the signals of the input terminal In. In other words, two completely different logical circuits can be obtained by the existence or nonexistence of the implanted impurities to the channel.
