Title: Memory protecting circuit
Inventor: TSUCHIYA KEN
IPC: G06F12/16
Filed: 1989-04-27
Abstract: PURPOSE:To execute the memory protection of a short term and a long term by supplying a short term protective power source by a small capacity capacitor, and supplying a long term protective power source by a large capacity capacitor. CONSTITUTION:When a power source is supplied to an input terminal 1, the supplied power source is supplied to a memory through a diode 11 or 2, 8. Simultaneously, the power source is supplied to a large capacity capacitor 9 and a small capacity capacitor, as well through a resistance 10, therefore, these capacitors are charged. Subsequently, when the power source is turned off, the power source is supplied to the memory from the capacitor 3 and 9 and the memory is protected. That is, since the capacitor 3 completes charging in a very short time, when the power source is turned off, the memory is protected by discharge of the capacitor 3. Also, even if the discharge of the capacitor 3 is ended first, since discharge from the capacitor 9 is continued for many hours, the memory can be protected extending over a long term.

CONSTITUTION:A detecting beam 201 for tilt of a recording medium 202 is made incident obliquely to a flat part of the medium 202. The reflected light of the beam 201 is led to a condenser lens 203 set so that its optical axis is paralle to the reflected light. Then the reflected light is received by a position detector 204 which is set approximately at a rear focal position of the lens 203 so that the photodetecting surface is set nearly vertical to the optical axis of the lens 203. Here the medium 202 has a tilt by DELTAtheta as shown by a broken line in the figure. In such a case, the reflecting angle of the beam 201 has a displacement by 2DELTAtheta and the photodetecting point moves by DELTAx on the detector 204. Then DELTAx=2fDELTAtheta is satisfied, where (f) shows the focal distance of the lens 203. Thus the tilt angle DELTAtheta of the medium 202 can be obtained.
