Filed: 1986-07-29
Abstract: PURPOSE:To reduce rotation waiting time as less as possible when data exist in adjacent cylinders and to improve the throughput of a magnetic disk control device by shifting the index patterns of the adjacent servo tracks by a specific angle. CONSTITUTION:An index pattern 3n is recorded in the n-th servo track 2n on a servo track surface 2 and an index pattern 3(n+1) is recorded in the (n+1)th servo track 2(n+1). The index pattern 3(n+1) is recorded on a position shifted from that of the index pattern 3n by 90 deg.. When the index pattern 3n in the servo track 2n on a servo disk surface 1 is passed under a servo head 4, an index signal is detected. Consequently, 'seaking time + rotation waiting time' can be minimized and data transfer time can be also minimized.

Title: Parachute
Inventor: TOMINAGA FUMIAKI
IPC: B64D17/66
Filed: 1991-07-18
Abstract: PURPOSE:To open a parachute surely even under any circumstances in an air current by installing a form memory alloy in a cloth canopy after being folded in its frame form, and restoring it to a beam form by means of heating. CONSTITUTION:A form memory alloy 2 is sewn in a cloth canopy of a parachute after being folded in its frame form. When this parachute is discharged in the air, especially at the time of supersonic speed, it canes to a high temperature because of friction with air, and with this heating, the form memory alloy 2 is restored to the original beam form as unfolded, forcibly opening the parachute wide enough. In addition, for such a case that aerodynamic heating is not fully expected for some reason or other at a time when the parachute is discharged in the air, a heating device 4 is installed in and around the form memory alloy 2 in advance, and after the parachute is released into the air, or simultaneously discharging it, heat is added to the alloy 2 by this heating device 4, having it restored to the original beam form, thereby forcibly opening the parachute. This method may be done as well.

Title: Accelerating power source
Inventor: MATSUOKA MAMORU
IPC: H05H5/02
Filed: 1983-09-27
Abstract: PURPOSE:To enhance the reliability by using a semiconductor switch and a voltage sharing element without using a power tube. CONSTITUTION:The voltage of a load 18 is controlled by controlling ON, OFF the first semiconductor switches 311, 312,..., 31n by a controller 40. When the applied voltage of the load 18 is raised as compared with the set value 22 in the controller 40, an OFF command is applied to any of the first semiconductors 311, 312,..., 31n, such as, for example, to 311. As a result, the applied voltage of the load 18 is decreased by the voltage shared by a voltage sharing element 321, but if the load voltage is still higher than the desired value, the OFF command is applied also to the first semiconductor 312. Thus, the voltage of the load 18 is controlled to the desired value. Thus, since no power tube is used, the reliability can be improved.

Filed: 1984-08-30
Abstract: PURPOSE:To prevent generation of erroneous synchronous pull-in by transmitting a space signal of '1' or '0' instead of sending out data when a departure from the synchronization in the opposite station is detected by a data time- division multiplexer. CONSTITUTION:When a receiving register 18 receives a frame signal RF from a transmitting register 27 in the opposite station, it transmits head information RS and control pattern position information RC to corresponding synchronous signal detector 15 and control pattern receiver 16. If the synchronization is not established, a detector 15 provides an asynchronous signal X to a control pattern transmitter 14, and a control pattern reciever 16 outputs an asynchronous signal Y to a selector 13. Then, a frame which is obtained through replacement of data F1 and F2 of an ordinary frame with a mark signal MARK, is transmitted from a transmitting register 17 to a receiving register 28. A synchronous pattern generator 12 is generated from a synchronous pattern signal SYN. A mark signal MARK which is totally '1' or '0' is generated from a selector 13 under control of signal Y, and a control pattern CONT is generated from a control pattern transmitter 14 under control of signal X, these signals being fed to a transmitting register 17.
