Title: Laser modulating circuit for optical disk recorder
Inventor: TOKIWA KAZUNORI
IPC: G11B7/125
Filed: 1989-12-18
Abstract: PURPOSE:To prevent the degradation of tone quality by inputting an EFM signal to a laser driving circuit through a delay circuit and controlling the extent of delay of the delay circuit with the error signal of a servo amplifying circuit to the reference speed of a spindle motor. CONSTITUTION:The EFM signal outputted from a CD encoder 10 is delayed by a delay circuit 15 and is inputted to a laser driving circuit 11. The output current of the circuit 11 is modulated by the EFM signal and flows to a laser diode 12 of an optical pickup, and an optical disk 13 is irradiated with the light emitted from the diode 12 to form a bit string. Since the circuit 15 advances or delays the signal in accordance with increase or reduction of a control pulse, the output of an adder 4, namely, the error signal of a servo amplifying circuit 3 has the frequency converted by a voltage controlled oscillator 17 and is inputted as the control pulse. Thus, the frequency of the EFM signal of laser modulation is changed in accordance with the change of the rotational speed of a spindle motor 7 to always form accurate bit length on the disk without an influence of the variance in rotation of the disk.

Title: Reel base elevator for magnetic recording and reproducing machine
Inventor: MIYAWAKI CHIKANORI
IPC: G11B15/32
Filed: 1989-12-18
Abstract: PURPOSE:To smoothly elevate a reel base with an excellent power transmission efficiency and a high reliability by putting the elevating shaft of the reel base and a part, on which the force to elevate the reel base acts, on the same axis. CONSTITUTION:When a gear part 2b of a rotating member 2 is driven by a driving source motor and a gear omitted in the figure, the member 2 is rotated to change the extent of engagement between a screw part 2a and a tapped hole 3a of a base 3, and the height of the base 3 is changed in accordance with this change. Though the base 3 receives the rotating force in a plane parallel with a foundation by rotation of the screw part 2a at this time, the base 3 is not rotated by whirl stop due to a supporting shaft 6 and is only elevated. As the result, a reel base 5 is elevated in accordance with the elevating operation of the base 3. When the reel base 5 reaches a prescribed height, rotation of the driving source motor for the elevating operation is stopped, and a rubber idler or the like is pressed to the outer peripheral surface of the reel base 5 to transmit rotation to the reel base from the external, thereby rotating the reel base 5 in the rise position.

Title: Measuring method for film thickness by x-ray diffraction method
Inventor: ISHIDA HIDENOBU
IPC: G01B15/02
Filed: 1990-11-27
Abstract: PURPOSE:To achieve a highly accurate measurement which are not affected by influence of an orientation property of a polycrystalline film regardless of intensity of diffracted X-rays related to a polycrystalline film by measuring only intensity change of diffracted X-rays from a substrate when incidence angle of X-rays is changed. CONSTITUTION:While an incidence angle of X-rays for a sample 1 is fixed to a speci fied value gamma1, a second solar slit 5 and an X-rays detector 6 are scanned over a speci fied angle range and a diffraction angle 2theta1 of diffracted X-ray peak from a substrate S and a diffraction intensity I1 are measured. Then, an incidence angle of X-rays for the sample 1 is changed for obtaining r2 and a diffraction angle 2theta2 and a diffrac tion intensity I2 of a same diffracted X-rays peak from the substrate S are measured similarly. This procedure is repeated by changing the incidence angle gammai and each diffraction intensity Ii ( i = 1, 2, ... ) and incidence angle gammai ( i = 1, 2, ... ) is mea sured. In this manner, only intensity change of diffracted X-rays from a substrate when the incidence angle from X-rays for the sample is changed is measured, which is not related to intensity of the diffracted X-rays related to a polycrystalline film, thus preventing influence of orientation property of the polycrystalline film.
