Title: Method for correcting offset of optical disc device
Inventor: YOSHIMOTO KYOSUKE
IPC: G11B7/095
Filed: 1990-11-09
Abstract: PURPOSE:To eliminate the offset of an OR signal caused by stray lights created in an optical head securely by a method wherein the existence of an optical disc to which a light is projected is detected and, when it is detected that the disc exists, a focusing lens is moved along the direction of a light axis and then the level of the OR signal is adjusted. CONSTITUTION:If a focusing point can not be obtained at the projection position of an optical disc 6 when a focusing lens 4 is moved, the level of the output PPM of an optical head PH is zero and the level of an OR signal detected by an OR signal level detecting circuit 24 is zero. However, if stray lights are created in the optical head PH, the stray lights which are lights other than the lights reflected by the optical disc 6 are concentrated to a halving photodetector in the optical head PH and the output PPM of the optical head PH is not zero and an offset is created in the OR signal detected by the circuit 24. In order to eliminate the offset caused by the stray lights, the OR signal level when a laser diode 1 emits a light and the OR signal when the laser diode 1 does not emit a light are made to be equal to each other. Then, after the lens 4 is moved along the direction of a light axis by a CPU 21, the optical head PH is made to emit a light intermittently.

IPC: H04H20/88
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To remarkably reduce the influence of a multipath effect to a reproduced tone by allowing time for returning from monophonic reproduction to stereophonic reproduction to depend on the relative frequency, intensity and length of the multipath effect. SOLUTION: A multiplex received signal reaches a stereophonic recoder 1 and is outputted from there as a sound frequency signal for right and left reproducing channel. In addition the received signal is guided through a multipath detector 2 detecting the generation of multipath interference. A circuit 3 recognizes the frequency, intensity and length of multipath interference, and the output signals of the circuit 3 and the detector 2 form a signal for controlling a stereophonic base area by means of a processing circuit 4. This processing circuit 4 determines the reproducing components of stereo reception by depending on a rate to the reproducing components of monophonic components and when receiving a signal given intense and long multipath interference, the reproduced tone is generated to be permissible in view of the received signal being interfered.

Title: Variable wavelength filter control method, variable wavelength filter control equipment, and optical communication system using the same
Inventor: KUBOTA OICHI
IPC: H04B10/564
Filed: 1993-12-06
Abstract: PURPOSE:To eliminate synchronous wavelength fluctuation due to micromodulation, by pulling the center wavelength of a wavelength filter into the wavelength of an optical signal by feedback control, stabilizing the center wavelength, and controlling a variable wavelength filter into which optical signal for receiving is introduced by an error signal. CONSTITUTION:An optical signal from an optical divider passes an optical waveguide 104, and enters a variable wavelength filter 401. According to a control signal from a filter driving circuit 404, the filter 401 transmits an optical signal having an arbitrary wavelength. A photodetector 402 converts the transmitted light from the variable wavelength filter 401 into an electric signal. An adder 403 adds an offset control signal 113 from a receiving part to an error signal 114 from a wavelength switching circuit, and delivers the obtained signal to the filter driving circuit 404. The injection current to the variable wavelength filter 401 is outputted according to the control signal from the adder. Since the center wavelength lambdaC<1> of the variable wavelength filter 401 is not modulated, the intensity fluctuation due to modulation is not generated in the optical signal after filtering.

Title: Cylindrical type guide apparatus having idle compensation of operation for fuel injection system
Inventor: MITOO MARUKU
IPC: F02M59/44
Filed: 1988-12-05
Abstract: PURPOSE: To control a volume of leakage fluid by making a hole of a needle as a passageway for the fluid be in association with a volume under a pressure effect for eliminating and/ or reversing the increase of the play of a guide in the hole. CONSTITUTION: A pressurized fluid from a canal 3A fills a volume 3 formed in a nozzle 2 and is distributed by a throat portion 1A of a needle 1 after having flowed through canal 2B. A flow of the leakage fluid is established in space 2C in the direction of two ends 4 and 5 of the contact between the needle valve 1 and the nozzle 2. Since the deformation of this kind of part is essentially determined by pressure difference between the exterior and the interior of the part, the external side of the inner material of the nozzle 2 constructing a guide is subjected to a certain pressure by the volume 3 while the internal side thereof is subjected to a pressure decreasing gradually due to space 2C, and the differential pressure compensates and decreases the change of the space 2C at a point 1A. As a consequence, the change of the initial play is compensated in some portions while decreased in other portions. In such a manner, a static leakage flow from the space can be controlled.
