Title: Indicating mechanism for video cassette
Inventor: MATSUI KAZUHIRO
IPC: G11B23/38
Filed: 1988-05-19
Abstract: PURPOSE:To properly classify a cassette and to put it in order by providing an indicating plate to describe an item to distinguish the cassette and an indicating part to indicate one of the described items of the indicating plate, at least, on the outside of a video cassette, and moving the indicating plate. CONSTITUTION:When a handle 16 is slided in the direction of an arrow mark 18 along the longitudinal direction of an open part 13, an indicated item on the indicating plate 12 is indicated in the open part 15. Then, when it is moved up to a position where a notch inside a mechanism storing part 10 is anchored to the anchoring groove 17 of the indicating plate 12, force to anchor it acts on the indicating plate 12, but when the handle 16 is slided further, anchorage between the anchroing groove 17 and the notch is released, and the indicating plate 12 can be moved without a break. Thus, the objective indicated item is indicated in the open part 15. In a state that the groove 17 is anchored to the notch inside the storing part 10, the indicating plate 12 never moves even if a case 1 is tilted. Accordingly, the item to distinguish the cassette can be easily indicated, and the picture-recording cassette is never demagnetized and re-recorded by mistake, and the cassette can be used effectively.

Title: Circuit for detecting backup power supply voltage
Inventor: SANO SHINYA
IPC: H02J9/06
Filed: 1982-07-14
Abstract: PURPOSE:To prolong the time available for backing up to the limit of the ability of an individual IC, by starting the reset of backup power supply voltage only when the backup power voltage is reduced down to VTP (threshold voltage of p- channel MOS FET) + VTN (threshold voltage of n-channel MOS FET) of individual IC. CONSTITUTION:When the backup power supply voltage V1 is higher than VTP+ VTN if a positive power source V2 which is not backed up is raised, current I1 flows into the MOS FETs P1 and N1 in the area of V2>VTN, but when lower than VTP+VTN, current I1 flows into the MOS FETs P1, N1 in the area of V1> VTP+VTN. Consequently, detection whether current flows into the MOS FETs P1, N1 in the area of VTN<V2<VTP+VTN makes it possible to discriminate whether the voltage V1 of the backup power supply is higher than VTP+VTN or not.
