Title: Plastic substrate for optical disk and its production
Inventor: INOTSUKA AKIHIRO
IPC: G11B7/2433
Filed: 1986-03-03
Abstract: PURPOSE:To obtain a recording medium having a high CN ratio by controlling the absolute value of the difference between the refractive index at right angles to the flat surface of a transparent plastic substrate and the refractive index parallel to the flat surface to <=4X10<-4>. CONSTITUTION:Information is carried by an appropriate carrier, and a laser beam is injected through the transparent plastic substrate arranged above the information. When the refractive index nZ at right angles to the surface of the plastic substrate is considered, the transparent plastic substrate 5 is supposed to have refractive indexes nX and nY parallel to the flat surfaces 6 and 7 and at right angles to each other and a refractive index nZ at right angles to the flat surfaces 6 and 7. Since linearly polarized light for observation was injected at right angles to the flat surfaces 6 and 7 in the conventional method for measuring birefringence, the birefringence due to nZ could not be observed. However, since the linearly polarized light 8 is inclined, for example at an incident angle of theta=30 deg., to the flat surface in this method, nZ can be observed. The CN ratio of a photomagnetic disk prepared by forming a photomagnetic recording film on a substrate wherein the values of ¦nZ-nX¦ and ¦nZ-ny¦ are lowered to <=0.0004 can be remarkably improved.

Abstract: PROBLEM TO BE SOLVED: To surely mount a bare chip on a circuit board and to demount the chip easily when the chip is defective and thereby prevent the destruction of the circuit board by forming openings in an interposer at the positions to correspond to input/output terminals of the bare chip. SOLUTION: An interposer 21 is laid on top of a circuit board 22 with openings 25 being aligned with pads 24 of the circuit board 22 and then a bare chip 20 is so laid on top of the interposer 21 that bumps 23 may be inserted into the opening 25.

Abstract: PURPOSE:To reduce the influence of the waveform mismatching of a ladder resistance upon distortion by setting a range of at least 12db from the maximum value of digital data as a maximum compression ratio range. CONSTITUTION:17-bit complementary code data of ''2'' is inputted from a terminal to a compression part; when at leat one of seven bits from the 16th to the 10th bits is 1, a sign bit is added to 13 bits from the 16th to the 4th bits to obtain significant number data and when the 9th and the 8th bits are 1 initially, bits shifted down each by one are regarded as the significant number data, obtaining an analog value from a 14-bit D/A converter 11. Then, it is sent to the resistance ladder circuit 13 of an expansion part 12 to be expanded. Since a large-level linear area is expanded by >16db, waveform mismatching, i.e. distortion due to a ladder resistance error is reduced.

Filed: 1993-03-08
Abstract: PURPOSE:To improve the detection accuracy of a rotation detector at a low rotational speed and, at the same time, to reduce the outside diameter of an FG magnet without deteriorating the detection accuracy. CONSTITUTION:Magnetism sensitive elements 31A and 31D for outputting a rotation detecting signal P1 and magnetism sensitive elements 31B and 3C for outputting another rotation detecting signal P2 are arranged at regular intervals which are equal to 1/6 of the pole width of an FG magnet 13 and a phase difference of about 60 deg. exists between the two signals P1 and P2. When the zero-crossing points of the two signals P1 and P2 and the difference signal 3 between the signals P1 and P2 are counted, the rotating state of the FG magnet 13 can be detected. In this example, the detection accuracy of the rotating state of the magnet 13 can be improved even when the number of poles of the magnet 13 is reduced, since the number of zero-crossing points becomes larger than the conventional ones. Therefore, the rotation of a capstan motor can be easily controlled even when the motor is miniaturized by reducing the outside diameter of the magnet 13.
