Title: Disk player
Inventor: FUJIWARA TOMONORI
IPC: G11B21/08
Filed: 1988-08-10
Abstract: PURPOSE:To perform roll control at the time of generating abnormality where no synchronizing signal is obtained and to prevent the abnormal rotation of a spindle motor by detecting the position of a pickup in the diameter direction of a disk from the quantity of rotation of a gear mechanism. CONSTITUTION:When the pickup and another supporting base 3 are driven and a switch (SW) 98 is turned on, a base 3 is sent from an inner periphery to an outer periphery, and a lower plane is reproduced, and the spindle motor 21 is rotated in a forward direction. The output of the output 15a and 15b of a photosensor are taken out via the gear mechanism, and phase difference is detected at a phase comparison circuit 120, and an up command is issued to a counter 121, and a count value is inputted to a conversion circuit 122, then, the position can be found. After the reproduction of the outermost periphery is completed, the base 3 is driven by the gear mechanism, and it arrives at an upper straight line traveling end via a circular arc shape guide part, then, a SW 97 is turned on. Traveling direction is reversed, and the base 3 is moved from the inner periphery to the outer periphery on a disk plane, and the motor 21 is rotated in a reverse direction, then, an upper plane is reproduced. By employing such constitution, the number of components can be reduced, and also, the abnormal rotation of the spindle motor can be blocked while performing the roll control with high accuracy.

Filed: 1986-08-29
Abstract: PURPOSE:To attain a coding with high quality even with a small signal power by applying the coding while stopping pitch prediction when the signal power of an input sound signal is small and assigning bit number used for the transmission of a pitch prediction coefficient to the quantization of a residual signal. CONSTITUTION:A quantization section quantizes a residual signal according to bit assignment information from the control calculation section 6 of an analysis section 2. Moreover, a pitch prediction section 5 forms a pitch prediction signal according to the pitch predicting coefficient from a control calculation section 6 of the analysis section 2 and uses a sum with a proximity correlation predicting signal from a proximity correlation predicting section 4 as a predicting signal. Moreover, at the silence of the input sound signal and at the interblock, the operation of the pitch predicting section 5 is paused, it is informed to the reception side by a control bit and the bit number used for the transmission of the pitch prediction coefficient is assigned to quantize the residual signal. Thus, the coding of the sound signal with high accuracy is attained.

Abstract: PURPOSE:To simplify the production and to improve the handling efficiency and the economization by providing a reflective face, which branches a part of the light propagated in a fiber and takes it to the outside, on the cut end face of a notch to branch and take out a part of the propagated light easily to the outside without requiring adjustment of an optical axis. CONSTITUTION:A derivative is vapor-deposited or a metallic paint is applied to the cut end face of a notch 7, which is formed on the side face of a plastic optical fiber 6 with a sharp-edged tool such as a razor, to form the reflective face. Since this reflective face which branches a part of the light propagated in the fiber 6 and takes out it to the outside is provided, an input light 8a out of input lights 8a and 8b propagated in the fiber 6 is reflected on the part of the notch 7 and is branched from the other input light 8b. Consequently, when the branch light reflected on the part of the notch 7 is made incident on a plastic optical fiber 9 for branch light output, a part of the optical signal is taken out to the outside and is used for monitoring the state of a light source or a transmission line.

Title: Phase change type optical recording medium and production thereof
Inventor: KAWAKAMI HARUO
IPC: G11B7/24035
Filed: 1990-07-30
Abstract: PURPOSE:To increase an erasing ratio from an initial state by adopting such track patterns as to equal the reflectivity of an unrecording region and erasing region at the time of erasing. CONSTITUTION:Recording marks 4 are formed as a 2nd phase state within a 2nd region zone 2 when writing is executed by irradiation with a laser beam along one line of the 2nd region band 2. The recording marks remain without being erased in the state of the 2nd phase state in the gap region of the diameter of the recording marks and the width of the laser beam if the marks 4 are erased by being irradiated with the low-power laser beam of the width narrower than the diameter of the recording marks 4 from this state. The 2nd region band 2 of the 2nd phase state is previously formed in the unrecording region as well and, therefore, if the reproducing is executed by scanning the laser beam in this state, the difference in the reflected light quantity between the unrecording region and the written and erased region is decreased. The fluctuation in the noise level by the writing and erasing is thereby lessened and the erasing rate is stabilized at a high value. Consequently, the recording medium is usable from the initial state.
