Title: Light guide
Inventor: TSUMANUMA KOUJI
IPC: G02B6/04
Filed: 1989-08-08
Abstract: PURPOSE:To improve the durability of a light guide by arraying many pieces of optical fibers and fixing the ends of these fibers into a fixing member by means of a heat-resistant transparent adhesive. CONSTITUTION:The heat-resistant transparent adhesive 10 is used for fixing the ends 5, 5... of the optical fibers 1, 1... in a terminal part 9 on a light source side. This adhesive 10 exhibits the heat resistance of <5% degradation in light transmittance at 0.38 to 0.78mum wavelength by heating at, for example, 250 deg.C for 24 hours. This adhesive is colorless and transparent and has the transparency of >=90% light transmittance in an IR region (0.4 to 5mum) from a visible region. Examples of the heat-resistant transparent adhesive 10 satisfying such conditions include silicone adhesive without contg. fillers and coloring agents. The adhesive layer at the ends consist of the heat-resistant transparent adhesive and, therefore, even if light of high energy is made incident to the end of such light guide, the ratio at which the light energy is converted to heat energy is small and the adhesive does not generate heat.

Filed: 1989-08-10
Abstract: PURPOSE:To prevent a servo motor from generating malfunction by stopping the drive of the servo motor in assuming as absolute position detecting abnormality when a difference between the rotational frequency of the servo motor which is obtained from the output pulse of a position detector and that obtained from the output pulse of a rotational frequency detector exceeds an allowable range. CONSTITUTION:A difference between the rotational frequency of the servo motor 5 from a reference point calculated from the accumulated value of position feedback variable and the total number of pulses generated by the one revolution of the position detector 6 and the rotational frequency of the servo motor 5 from the reference point counted up by the rotational frequency detector 7 is calculated, and when the calculated result exceeds a previously determined prescribed value, absolute position detecting abnormality is outputted. Namely, the rotational frequency from the reference point counted up by the detector 7 is compared with the rotational frequency calculated from the accumulated value of position feedback variable obtained from the detector 6, and when both the corresponding rotational frequency is shifted more than the prescribed allowable range, the operation of the servo control device is stopped in assuming as the absolute position detecting abnormality. Consequently, the generation of malfunction can be previously prevented.

Title: Disk cartridge
Inventor: KANO KIYOSHI
IPC: G11B23/28
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To discriminate similar but, different kinds of cartridges by providing deletion sections which are formed by deleting the external surface parallel to the disk surface of a disk against a different kind of a disk cartridge as a discriminating means and a stopping means. SOLUTION: A CD caddie discrimination hole 4s is provided on a side surface section 4c of a shutter 4 and a projecting section 210 is provided on a device 200 side corresponding to the hole 4s at the position where a disk cartridge is inserted to an innermost position. Then, the insertion of the disk cartridge is completed only when the section 210 fits into the hole 4s. When a sensor detects the fact that the cartridge is completely inserted to the completion position, the entire disk cartridge is moved to the disk rotation direction and the loading is completed for a reproducing. Since a CD caddie has no hole 4s, the section 4c of the shutter 4 impacts against the tip of the section 210 and an insertion is not completed.
