Patent JP-2000329586-A (JP)
Title: Optical encoder and production thereof
Inventor: YANAGAWA KATSUHIKO
IPC: G01D5/36
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To reduce the manufacturing cost, shorten the manufacturing time and enhance the reliability by setting the modulus of elasticity of a UV-curing elastic adhesive layer for bonding a hollow rotary shaft and a silt disc lower than that of the silt disc. SOLUTION: A hole 1a is made in the center of an aluminum hollow rotary shaft 1 and acry1-based UV-curing elastic adhesive is irradiated with UV-rays to form a UV-curing elastic adhesive layer 2. Even if a stress is generated due to difference in the coefficient of thermal expansion between the elastic adhesive 2 and a slit disc 3 using a polyester film substrate when an optical encoder is used under high temperature environment, the elastic adhesive layer 2 having a low modulus of elasticity absorbs the stress thus preventing the slit disc 3 for warping. Furthermore, a light emitting element 4 and a light receiving element 5 are disposed oppositely to each other interposing the slit disc 3 between them.  Light form the light emitting element 4 is intercepted by a slit part 3a or passed when the slit part 3a is not present and the light receiving element 5 outputs a detection signal correspondingly. A signal processing circuit 6 operates and output r.p.m. and rotational angle.

Title: Tape protecting device
Inventor: IWAIBANA KUNIO
IPC: G11B15/02
Filed: 1979-10-25
Abstract: PURPOSE: To prevent damages of magnetic tape, by providing the 2nd pulse generator and the like generating pulses in synchronizing with the rotation of a reel stand and the 1st pulse generator generating pulses repeated in a given period, and detecting the rotating state of the reel stand.  
     CONSTITUTION: A reference pulse repeated in a given period is fed to a counter 7 from a pulse generator 8 at recording/reproducing, and the count is started every reset. If the tape run stops due to any cause and the winding reel stand is not turned, since no reset pulse is fed from an amplifier 6, the 1st detected output is given to a filp flop (FF) circuit 9 by the counter 7 counting the reference pulses by N 1  units. Thus, the 1st control output which releases back tension is output from a terminal 11 to reduce the load of the reel stand. After that, when the counter 7 further keeps count and the 2nd detected output is given to a FF circuit 10, the 2nd control output is output from the terminal 12 and the tape recorder is at stop mode.

Filed: 1993-06-10
Abstract: PURPOSE:To enable automatic restoration when a signal conversion is abnormal by switching the driving signal of an operation terminal from the operation output of a 1st signal converting means to the operation output of a 2nd signal converting means according to an alarm signal. CONSTITUTION:An output backup device 20 includes a signal conversion part 21 equal to a signal conversion part 9 which inputs an analog control signal outputted by a D/A conversion part 7 and a switch 22 which switches the outputs of the signal conversion parts 9 and 21 with a read-back error signal 5c outputted by an arithmetic part 5. When the signal conversion part 9, i.e., a read-back signal 2 is normal, the signal to the operation terminal 11 is supplied from the signal conversion part 9. If, however, the signal conversion part 9, i.e., read-back signal 2 becomes abnormal, the arithmetic part 5 outputs the read-back error signal 5c as an alarm, the switch 22 switches the signal conversion part 9 to the part 21. Thus, even if the signal conversion part 9 becomes abnormal, normal operation can be carried on.
