Title: Magnetic recording and reproducing device
Inventor: NISHIMA AKIRA
IPC: G11B15/61
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To provide the helical scan type VTR which stably conducts a variable speed reproducing. SOLUTION: The winding range of a magnetic tape against the peripheral surfaces of an up drum Du and a down drum Dd is set more than 180/N degrees (where N is the number larger than 2) which is the angle viewed against the both ends of the winding range of the tape on the drum peripheries from the center of the drums. Moreover, rotary magnetic heads Ha, Hb, Hc and Hd are provided at the positions which are determined by equally dividing the peripheral surfaces of the drums by 2N.  During a variable speed reproducing, even though the central shaft of the drums is tilted so that the angle defined by a reference edge Te of the magnetic tape, which is wound to a portion of the surfaces of the peirpheries of the up and down drums, and the rotary locus surfaces of the heads Ha to Hd are matched with the normal track angle of the recording track of the tape, the gap between the position control surface of the edge Te formed on the top surface of a read ring Lr of the device and the edge Te is made small. Thus, the position of the edge Te of the tape is surely controlled by the position control surface of the ring Lr during a variable speed reproducing. Furthermore, the recording and reproducing operations by the magnetic tape, which is made of the base material that is thin and has a lower rigidity, are conducted without any problems.

Filed: 1986-08-06
Abstract: PURPOSE:To prevent overvoltage, by connecting a main output winding and an excitor winding in series and by making up an auxiliary output winding by the use of a part of the excitor winding. CONSTITUTION:In order to prevent the danger from cross contact, a separated winding structure from a main output winding Mw is adopted in making use of a part of an excitor winding EXw for the auxiliary output winding DCw. On the other hand, so as to eliminate undesirable influence on the auxiliary output due to a magnetic flux, the excitor winding EXw is divided into two in approximately equal parts and the windings thus divided are arranged at both angles almost symmetrical to the line forming a space angle of 90 deg. with the main output winding Mw. The both windings are connected in series, while an auxiliary output winding DCw is formed in making use of a part of the excitor winding on the side arranged at the angle smaller than 90 deg.. Thus, the combined flux direction with the connection in series with the main output winding Mw is almost the same as the flux direction when the excitor winding EXw is arranged at the angle of 90 deg..

IPC: H01L21/027
Filed: 1985-08-22
Abstract: PURPOSE:To contrive expansion of effective region by a method wherein the field of exposure is formed into an equilateral hexagon. CONSTITUTION:The equilateral hexagon 3 inscribed to the circle showing an effective resolving region 1 is used as the field of exposure. The coefficient of utilization in this case is worked out as 82.7% by making a simple calculation. Also, as it is considered that the number of shots is approximately in inverse proportion to the field of exposure, the number of shots required can be reduced approximately to 78% of the number required before, and when the number of shots is the main factor of the through put, the through put of approximately 1.3 times can be obtained. Also, when an equilateral hexagon is regarded as one chip, a scribe line does not become a straight line. However, the equilateral hexagon is divided into six parts, one chip becomes an equilateral triangle, all the scribe lines 11 become the straight lines inclined at the angle of 120 deg. with one another, and the trouble arising from pelletizing can be removed. As a result, through-puts can be obtained when compared with the optical system having the efficiency equal to that of the device manufactured heretofore.

Title: Drive mechanism of video tape recorder
Inventor: TSUYAMA MANABU
IPC: G11B15/30
Filed: 1984-09-06
Abstract: PURPOSE:To use parts in common between supply and take-up reel drive disks by attaching a yoke plate to the opposite side of a magnet set opposite to a hiss plate of either one of both reel drive disks and giving different torques to both drive disks. CONSTITUTION:The gear of a drive mechanism engages the tooth 2A of a lower reel drive disk 2 or a gear 6 and revolves at a take-up reel drive disk T. Thus the disk T also revolves. When the drive gear 6 is revolved, a magnetic flux generated from the other side of a magnet 3 is sent back to a magnet 3 through a yoke 11 since this yoke 11 is attached to the magnet 3. In this case, the density of the magnetic flux is higher than the disk T having no yoke plate 11. Then the revolving torque of the disk T is larger than that of a supply reel drive disk. Thus different torques can give to the supply and take-up reel drive disks although both disks have almost the same structure. Therefore the components parts can be used in common to both drive disks. This attains the reduction of cost.
