Title: Magnetic tape loading device
Inventor: MIWA HIROSHI
IPC: G11B15/61
Filed: 1983-05-24
Abstract: PURPOSE:To prevent a magnetic tape and a magnetic head from damaging by varying the inclination of a cylinder so that the angle beta of the entrance of the magnetic tape on the cylinder is equal to the slanting angle eta of a lead for a tape guide which is worked projecting on the cylinder while the magnetic tape is loaded. CONSTITUTION:The cylinder 17 is set at the same slanting angle as the lead slanting angle eta by a driving link 26 which rotates the cylinder in the early stage of tape loading. The magnetic tape is drawn out by a roller after a cassette is loaded on a base 17, and then contacts the cylinder 17. The slanting angle of the cylinder does not vary during said period. The magnetic tape contacting the cylinder 17 is further wound around the cylinder 17 with a pin and the roller and thus loaded lastly. The cylinder 17 rotates around a bearing 23 by a driving link 26 linked to the link driving device for a shaft according to the motion of the pin and roller, and the slanting angle of the cylinder is controlled by the driving link accurately to attain to beta=eta.

Patent JP-S63258170-A (JP)
Title: Automatic focus adjuster
Inventor: SHIMURA HIDEYUKI
IPC: H04N5/232
Filed: 1987-04-15
Abstract: PURPOSE:To prevent an erroneous focus adjusting action because of that no differential signals are obtained due to a large defocussing status by selecting a differential signal whose level exceeds a prescribed level form among plural differentail signals obtained based on plural different delay times, and controlling the focus so that the time duration of the signal comes the shortest. CONSTITUTION:An arithmetic processing circuit 15 checks the signal level of two differential signals obtained from detectors 14a, 14b by comparing and discriminating them, measures the time duration of such one of the differential signals as exceeding the prescribed level, and outputs a control signal to a motor drive circuit 11 so that the time duration of the signal comes the shortest. In the case of a large defocussing amount, the control is so executed that the time duration of a differential signal from a delay element 7b whose delay time is long comes the shortest; when the focusing state is approached due to said control, the level of a differential signal from a delay element 7a whose delay time is short also comes higher. Therefore, by switching the drive-control of such a lens that makes the time duration of a differential signal from the delay element 7a of short delay time shortest, the accuracy of the focussing can be improved.

CONSTITUTION:A transparent film 2 consisting of the fluid synthetic resin having chemical resistance is applied on the surface of a release sheet 1 having a release property and the transparent globules 3, 3' consisting of inorg. microglass are sprayed atop this layer to form the optical retroreflecting layer. The transparent particle film 4 consisting of the fluid synthetic resin is then applied atop the optical retroreflecting layer A so that the transparent particle film 4 is tightly adhered to the optical retroreflecting layer A. The many small reflectors 6 of an arbitrary shape which are segmented separately by sealing cavities 5, 5' are thereafter tightly laminated atop the transparent focus film 4. Further, both of the front surface of the small reflectors 6 and the peripheral end edge surfaces thereof and the surface of the sealing cavities 5 are tightly coated, sealed, dried and vapor deposited with a protective film 7. The corrosion of the optical retroreflector by an alkaline component and the corrosion thereof by a salt component are prevented in this way and the strong reflecting power is maintained. The reflector with withstands long-term use is thus obtd.

Filed: 1989-04-14
Abstract: PURPOSE:To obtain a compact pulse generation circuit at low cost by charging a capacitor with the + side half wave of a power source for capacitor charge and forming the gate driving signal of a thyristor with a - side half wave, CONSTITUTION:The voltage of the + side half wave in an alternative current power source 11 charges capacitors 15a-15c to a prescribed polarity through the coil of a transformer 24, diodes 13a-13c and resistors 14a and 14c. When the alternative current power source 11 is the - side half wave, diodes 26a-26c are conducted and a gate driving current is supplied through resistors 27a-27c to thyristors 17a-17c. Then, the thyristors 17a-17c are turned on. Afterwards, the capacitors 15a-15c are charged by the + side half wave of the alternative current power source 11 again and this operation can be repeatedly executed. Thus, since the gate driving signal of the thyristors 17a-17c is obtained by the - side half wave of the transformer 24 for charge, the gate driving circuit of the thyristor is simplified and the compact pulse generation circuit can be obtained at low price.
