Title: Spread spectrum receiver
Inventor: IMOTO KATSUYUKI
IPC: H04J13/00
Filed: 1982-05-14
Abstract: PURPOSE:To perform stabilized communication by keeping synchronization even in low receiving conditions, by controlling the threshold level of a synchronizing detector according to the condition of receiving. CONSTITUTION:When shifted to tracking mode, an input signal Vd for a synchronizing detection circuit 10 is inputted to a memory 14 and a terminal 19 of a differential amplifier 5'. The memory 14 picks up the max. value of the signal Vd to input to the other terminal 20 of the amplifier. Since voltages inputted to the terminals 19 and 20 of the amplifier 5' are equal to each other in the effective area of an AGC, the output of the amplifier is zero. Therefore, a controlling part 16 does not operate, and the threshold level voltage Vs of a circuit 13 for setting threshold level continues to be the previous value. However, if enters the ineffective area of the AGC, the signal Vd lowers to induce voltage in the output of the amplifier 5' that lowers the voltage Vs through the control part 16. As a result, a code error rate is not deteriorated, and better communication is realized even in the ineffective area of the AGC.

Title: Optical memory device
Inventor: SATO YOSHIO
IPC: G11B7/0045
Filed: 1986-04-09
Abstract: PURPOSE:To rewrite the contents of an optical memory at a high speed without deteriorating the heat stability by adding a means to a conventional optical memory device to cause the magnetic flux change. CONSTITUTION:An optical disk device 10 records, reproduces and erases the information or data via an optical head 40 which is controlled by a signal processor 150. Here a magnetic flux generator 20 is added to the optical disk 10 for generation of a magnetic field. As a result, an eddy current is produced within the disk 10 and therefore the disk 10 is heated. Then the information or data recorded to the disk 10 are erased when the temperature of a recording medium of the disk 10 reaches an erasing level. The generator 20 also contributes to improvement of the recording sensitivity. That is, the heating load of the head 40 is reduced as long as the heating temperature is kept under the erasion level when the recording medium is heated by the eddy current. Furthermore, the time needed to reach a recording temperature is shortened.

Abstract: PROBLEM TO BE SOLVED: To increase luminance and to prevent ocurrence of an unclear image formed due to parallax by providing a diffusion film with characteristics such as the low rear diffusion, low polarization cancel and no phase difference of light and allowing a polarizing plate to absorbe rear reflection and increase the contrast. SOLUTION: A beam 21 parallel with a polarizing plate light transmission direction out of incident light is passed through a polarizing plate 201 and converted into a circularly polarized light 21a by linear polarization and a transmitted beam 21b is still circularly polarized light by the characteristics of low rear diffusion, low polarization cancel, and no phase difference included in a diffusion film 203. Since the polarization state is not changed when a beam 21d reflected by a reflection layer is passed through the film 203, the circular polarization direction of beams 21e, 21a are mutually reversed.  The beam 21e and rear diffusion light 21c are passed through a 1/4 wavelength phase difference film 202 and converted into linearly polarized light 21f, the polarizing direction of the light 21f becomes rectangular to that of the incident light 21, so that the beams 21c, 21e can not be passed through the polarizing plate 201, rear diffusion is almost removed and a contrast value can be sharply improved.

Filed: 1982-05-17
Abstract: PURPOSE:To facilitate input and output matching and to increase a gain without the need for a DC cutoff capacitor by providing the 1st and the 2nd field effect transistors, a load resistance, a level shifting circuit, and a feedback circuit on the same substrate. CONSTITUTION:The amplifier consists of a source earth amplifier consisting of an n channel FET T1 and a load resistance RL, the source follower equipped with the constant current circuit consisting of the level shifting circuit consisting of diodes D1-D5, FET T2 and an (n) channel FET T3, and a negative feedback resistance Rf. The load resistance is settable to a large value because the input impedance of a trailing-stage source follower is high. Since Vp=-2V, the DC level of an output is equalized to the optimum DC bias level of an input through the level shifting diodes D1-D5, which serve as a gate bias circuit for the input. The number of the diodes is optimized by being varied at Vp. Further, Rf is selected properly to perform input and output matching over a wide range.
