Title: Bidirectional optical tuner
Inventor: HAGIWARA KIYOKAZU
IPC: G02B6/293
Filed: 1987-11-12
Abstract: PURPOSE:To provide a bidirectional optical tuner having the simple structure capable of receiving only the light of a necessary wavelength from plural wavelengths in a piece of a photodetecting element and capable of condensing and sending an up signal to an output optical fiber by means of a half mirror by providing a rotating mechanism to a holographic diffraction grating and projecting signal light linearly on the photodetecting element, then subjecting the signal light to photo-electric conversion. CONSTITUTION:An electric signal is entrained in a light source 9 and is reflected via a lens 8 by the half mirror 7 and the reflected light is condensed via a lens 2 to an output optical fiber 10 in the case of sending the up signal. The half mirror 7 is provided with such optical film which allows transmission of the light of the wavelength from the input/output optical fibers and reflects the light of the wavelength from the light source. The half mirror 7 is fixed and is capable of sending the signal regardless of rotation of the holographic diffraction grating 1. The wavelengths to be used are particularly arbitrarily selectable in order to transmit the signal for transmission by entraining the same in the independent optical fiber.

Title: Controlling apparatus for dish washer
Inventor: ITO YOSHINOBU
IPC: A47L15/46
Filed: 1987-11-12
Abstract: PURPOSE: To prevent the overflow state of washing water into a washing tank and to prevent the damage of a part such as the seal part of a washing pump, in a control apparatus for a tableware washing machine, by taking a notifying method different corresponding to the kind of an abnormal state when an abnormal state is generated in the float of a float switch. CONSTITUTION: If an output signal is generated from an output signal generation means 5, a clocking means 6 clocks the elapse time after the generation of the output signal and a water supply valve 3 supplies the washing water from a water supply source 1 into a washing tank 2 by the opening thereof. In this state, when the clocking time of the clocking means 6 reaches a first predetermined clocking time though a water level detection signal is not generated from a float switch 4, a first information signal generation means 7 allows the output signal from the output signal generation means 5 to disappear to generate a first information signal. The information means 9 emits information in a predetermined information mode.  When a water level detection signal is generated from a float switch 4 before the clock time of the clocking means 6 reaches a second predetermined clocking time, a second information signal generation means 8 allows the output signal from the output signal generation means 5 to disappear to generate a second information signal.

Filed: 1993-10-22
Abstract: PURPOSE: To surely access a sector immediately after a band boundary which was unusable before when a logic track on an optical disk is grouped into concentric bands. CONSTITUTION: When the sector off an access target is the first sector 60 of the band N, a head is radially moved, a clock frequency is set to fN-1 of a preceding band and a laser beam is lowered to the sector 45 for instance.

A controller 22 is housed in the ROM of a memory 36, identifies the sector 50, calculates delay time, makes mark detection inoperable and switches the fN-1 to fN. The mark after the mark detection is made operable again is the first mark after a boundary between N-1 and N. The mark 605 of the target sector 60 is detected, ID information is read, and when the target is finally found, the sub system accesses the user area of the sector 60 and operates data.
