Title: Optical disk device
Inventor: KUMAGAI EIJI
IPC: G11B7/004
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To always discriminate correctly a kind of a loaded optical disk, e.g. whether the optical disk is a CD or a DVD. SOLUTION: In the case of loading, e.g. a DVD 100, a time difference Ths between a pulse 107 resulting from a peak 103 caused by surface reflection and a pulse 108 resulting from a peak 104 caused by reflection on a signal side in a signal binarizing a sum signal based on a reflected light is measured. Furthermore, a time difference Tfs between pulses 111, 112 based on S-shaped signals resulting from reflection on the signal side in a signal binarizing a focus error signal is measured. A ratio Ths /Tfs is calculated from the measured values. Similarly to the case above, a ratio Ths /Tfs of a CD 200 is calculated.  Since the ratio Ths /Tfs denotes it that the effect of dispersion in the sensitivity in a focus direction of an actuator moving an objective lens 24 is eliminated based on the time Ths reflecting a thickness of a substrate of the optical disk, a type of the optical disk is correctly discriminated based on the ratio Ths /Tfs .

Filed: 1987-12-14
Abstract: PURPOSE: To simplify a sorting mechanism and to facilitate manufacture by inverting fresh flower receiving arms by disengaging floating shaft turning preventive pins in the sections corresponding to the detected lengths of fresh flowers in the transporting direction of the fresh flower receiving arms. CONSTITUTION: While the floating shaft turning preventive pins are slid on stationary guide rods 4 by turning of a chain 10, the transportation of the fresh flower receiving arms 17 is started. The fresh flowers transferred from guides 321 to the fresh flower receiving arms 17 pass the lower side of microswtiches 302A to 302D as they are transported. Detecting rods 303A to 303D are pressed according to the lengths thereof and the corresponding solenoid devices 301A to 301D are actuated by the switches of the changed over contacts. Consequently, independent moving short rods 3 part from the stationary guide rods 4 and the engagement with the floating shaft turning preventive pins is disturbed and, therefore, floating shafts 6 are inverted by their own weights of the fresh flower receiving arms 17 and the fresh flowers.  The fresh flowers are thus dropped and housed into prescribed fresh flower receivers.

IPC: H04L1/00
Filed: 1987-12-16
Abstract: PURPOSE:To attain error correction in an error correction decoder by connecting a delay circuit compensating a delay due to a delay circuit corresponding to a signal of each series to an error correction decoder so as to make equivalent to one bit error. CONSTITUTION:An output signal of each series of the error correction coder 1 is subject to a different delay corresponding to each series by a delay circuit 9 to apply gray coding and the result is subject to orthogonal amplitude modulation and sent. The reception side demodulates the signal and converts it into a digital signal by an A/D converter 6 and the gray code is converted into a natural binary code by a gray decoder and the result is retarded by a delay circuit 10 compensating the delay of the delay circuit 9 at the sender side and the result is given to an error correction decoder 8. Thus, even if all bits in one symbol are in error by a mis-coding in the A/D converter 6, it is possible to apply error correction by the error correction decoder 8 as one bit error.
