Title: Signal recording-reproducing system
Inventor: MIMA SOUICHIROU
IPC: G11B20/12
Filed: 1978-02-21
Abstract: PURPOSE:To reduce the effect of drop-out and skew by recording upper bits in the tracks at both side ends of tape and lower bits in the tracks of the central part at the time of recording digital data in multitracks. CONSTITUTION:At the time of parallel recording signals of, e.g., 10 bits in the width direction of a tape (a), they are recorded in b1 thru b10 from the upper bits then the same signals as those of b1 thru b5 are respectively recorded in the tracks of b1' thru b5' so that the entire number of the tracks is made 15. Hence, by letting the central track b be a reference for synchronization and at the reproduction, adding and combining the signals like b1 and b1', b2 and b2', the effect of drop-out and skew may be reduced. In addition, the distance from the reference track and the skew for the reference signal are nearly proportional and therefore the skew of the track signals of b6 thru b10 may be reduced as well.

IPC: F26B5/06
Filed: 1990-01-30
Abstract: PURPOSE:To permit the decision of the finishing time of drying by freezing in a short period of time by a method wherein the removal of refrigerant is detected from the change of weight of frozen body in an evacuated vessel when solution, in which dissolved substance is dissolved, is added with refrigerant to freeze the solution instantaneously, then, the dissolved substance is removed while evacuating and heating in the vessel. CONSTITUTION:The tray unit 1 and a supporting unit 3 on a heating unit 2 of a weight meter are formed of aluminum while both ends of a load cell 4 are held by the aluminum members. Suspension is made by fixing the powder of ZrO2, aluminum sulfate and water, for example, while the suspension is thrown into liquid nitrogen to make a material 5 by making frozen grains. When the material 5 is put on the tray unit 1 of the weight meter and the weight meter is installed in the evacuated vessel of a freezing drying device, then, an evacuating system is operated to evacuate the inside of the vessel and electric power is conducted through the heating unit 2, heat from the heating unit 2 heats the material through the supporting unit 3, the load cell 4 and the tray unit 1. On the other hand, when the weight of the material 5, put on the tray unit 1, is changed, the resistance of the load cell 4 is changed and, therefore, the weight of the material 5 can be known in a high accuracy. The time of drying is determined by a time when the total weight of the powder of ZrO2 and Al2(SO4)3 is achieved.
