Title: Groove forming method of master disk
Inventor: HAMADA MITSURU
IPC: G11B7/26
Filed: 1983-03-31
Abstract: PURPOSE:To form a trapezoidal groove of a stable form by providing resist layers different in sensitivity between its upper and lower layers on a glass disk and irradiating the laser light of the same wavelength to the resist layer by changing the laser power to form a shallow groove and a deep hole. CONSTITUTION:The 1st resist layer 10 is spin coated on a glass disk 5 with lambda/8 thickness and then prebaked, and then the 2nd resist layer 11 of lambda/8 thickness is spin coated and prebaked. Thus the layer 10 is prebacked twice owing to the prebaking of the layer 11 and therefore the sensitivity of the layer 10 is deteriorated compared with the layer 11. Thus the exposure power is increased to give the exposure up to a glass surface 5 of the layer 10; while only the layer 11 is exposed when the exposure power is reduced. With development and fixing processes, a shallow trapezoidal groove 13' of lambda/8 is especially formed into a stable form. Thus the track following of a head is stabilized for an optical disk medium using such a master disk 14.

Title: Positioning system
Inventor: INOUE TOSHIHIRO
IPC: G01S5/02
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To provide a system for realizing a highly accurate Doppler positioning by enhancing the accuracy of Doppler frequency measurement. SOLUTION: Doppler measurement is repeated a plurality of times within a time interval extremely close to the measuring time and the relationship between an obtained measuring time and Doppler measurements is approximated by a function. If a Doppler measurement is larger than a value preset by the approximate function, it is excludes as an error measurement from the object for averaging the Doppler frequency f. Positioning operation for obtaining a positioning solution (any one of true or false solution) is effected before starting a conventional positioning operation and a logical Doppler frequency to be received by a positioning system is determined from the positioning solution. It is then compared with the Doppler frequency f and a data reflecting incorrect Doppler measurement is removed to obtain an error free Doppler measurement data being employed for positioning.

CONSTITUTION:The diamond-shape polarized beam splitter having a diamond- shape main section is used for a light isolator as a polarizer. Since the reflected light R1 at the incident end surface 11 is reflected at the angle psi1=2theta1=30 deg. against the incident light I and reflected light R3 at a projection end surface 12 is reflected at the angle of psi2=2theta2=19.6 deg., both the reflected light rays are sharply separated from the incident light L and are not returned to the light source side. In addition, an angle formed by the joint surface 13 with the normal line is theta3 47.5 deg. and the dimming ratio (Tp/Ts) of the polarized beam splitter 5 corresponds to that obtained when the incident angle theta3 on the joint surface 13 is 47.5 deg., so that the rate of about 7,600 to 1 is obtained and proper polarization can be attained similarly to the proper incident angle of 45 deg. by a normal beam splitter.
