Title: Mobile object communication equipment
Inventor: ITO KOICHI
IPC: H04W92/04
Filed: 1993-06-25
Abstract: PURPOSE:To simplify the configuration of a retransmission base station and to reduce cost by relaxing characteristics requested to elements or transmission lines used for the retransmission base station when performing communication between a repeater station and the retransmission base station with optical signals performing analog AM modulation to radio signals to be respectively communicated between a base station and the repeater station and between a mobile station and the retransmission base station. CONSTITUTION:A repeater station 1 separates respective carrier wave signals, which are provided by receiving radio waves, with filter circuits 13a...13n and loads a fixed amplitude to those signals respectively with limiter circuits 14a...14n. Thus, since the amplitudes of signal waves contained in the respective carrier waves are matched, a low-priced Fabry-Pero resonator type laser diode can be used as an optical converting element, and a graded index optical fiber can be used as an optical fiber.

Title: Servo-signal recording method
Inventor: SETO HIDEKAZU
IPC: G11B21/10
Filed: 1991-05-31
Abstract: PURPOSE:To prevent the generation of a thermal off-track by detecting an off-track amount in a working temperature range, and correcting the off-track amount by using the off-track amount corresponding to roughly an average value of the range of the off-track amount. CONSTITUTION:When a servo-signal SS is written in a reference track, data DCO of a correction amount calculated, based on an instruction CTC of the number of moving tracks and data DIP read out of a memory 18 is supplied to a servo-controller 16 from a CPU 15. In this case, an off-track amount is corrected by using an off-track amount corresponding to roughly an average value of a range of the off-track amount in a working temperature range. The servo-signal SS is written by shifting from the center of the reference track by this correction amount. In such manner, an off-track margin is maximized, and generation of a thermal off-track in a secured temperature range of a wide range can be prevented.

Inventor: TSUKAHARA MAKOTO
IPC: G01J3/50
Filed: 1985-07-15
Abstract: PURPOSE:To obtain a device which can detect automatically and with a high accuracy a hue of a color surface, by obtaining color separation signals from light of the color surface, multiplying each of them by three basic vectors whose vector sum becomes zero, and thereafter, operating an angle of a composite vector. CONSTITUTION:Light of a color surface is brought to a photoelectric conversion by a color information reader (camera) 15, and three color separation signals R, G and B are generated and inputted to a color information processor 18.

Title: Method for measuring focal position of laser beam machine
Inventor: EDO TERUO
IPC: B23K26/046
Filed: 1989-06-20
Abstract: PURPOSE:To simplify measurement and control of the focal position of a lens by moving a working head to the direction of a work while the work is irradiated with laser beam from the working head, detecting the reflected light from the work and taking its maximum value for the focal position of the lens. CONSTITUTION:The working head 1 is lowered from the top dead center toward the work 5. At this time, when the focal position of the lens 4 is located above the upper surface of the work 5, the reflected light 2' reflected on the upper surface of the work 5 is diffused, only part of the reflected light returns to the lens 4 and since an amount of the reflected light detected by a power sensor 7 is small, the indicated value on a display 8 is small. Thereafter, when the focal position of the lens 4 reaches the upper surface of the work 5, the majority of the laser beams 2 returns to the lens 4 as the reflected light 2', consequently, the maximum value is indicated on the display 8. Further, when the working head 1 is lowered and the focal position of the lens 4 comes under the upper surface of the work 5, the reflected light 2' is diffused and the value of the display 8, too, reduces. Consequently, the maximum of the values of the display 8 indicates the focal position of the lens.

Title: Optical recording disk and optical recording and reproducing method
Inventor: AOI TOSHIKI
IPC: G11B7/24062
Filed: 1992-05-22
Abstract: PURPOSE:To precisely detect a tracking error by forming groups so that a tracking control loop gain is a specific value larger than the gain when a compact disk put on the market is reproduced. CONSTITUTION:The refractive index of a recording layer 3, the depth of grooves 23, and the thickness of the recording layer 3 at the groove parts are set within specific ranges. Consequently, when this disk is reproduced by a CD reproducing device, the tracking control loop gain at the time of tracking error detection by a phase difference method can be larger than -2 dB of the CD put on the market. Therefore, the tracking error detection is performed with the high gain value and tracking control becomes accurate; and a chapter search is made accurate and the access time is shortened.

Abstract: PURPOSE: To enable DC output to be clipped when pulse width becomes a fixed value or over and the clip value to be selected as desired by a monostable multivibrator circuit which is capable of arbitrarily adjusting the time whidth of output signal as well as AND circuit and averaging circuit.  
     CONSTITUTION: A monostable multivibrator 2 generates a pulse signal S 2  at the same instant when it is inputted with the pulse signal S 1  of a period T. Here, while the time widths T 1  and T 2  of level 1 of the signals S 1  and S 2  are holding the conditions of T 1  < T 2 , the output S 4  of an averaging circuit 4 is not clipped. Next, when these become time widths T 1  > T 2 , the averaging output S 4  is determined by the time T 2  and the DC output does not increase any more and it turns out that the output S 4  has been clipped. Hence, the clip value of the output S 4  is also changed by changing the output time width T 2  of the monostable multivibrator 2.
