Title: Optical filter device
Inventor: NODA HIDEKI
IPC: G02B6/293
Filed: 1983-11-14
Abstract: PURPOSE:To eliminate the need to replace the filter film of an optical demultiplexer and to improve operation efficiency and crosstalk characteristics by adding a detachable optical fiber device to a coupling fiber outside of the optical demultiplexer. CONSTITUTION:Light with wavelengths lambda1 and lambda2 from the incidence-side optical fiber 6 of the optical demultiplexer 1 is transmitted through or reflected by the filter film 3, and transmitted light with the wavelength lambda1 is converted by the 2nd lens 4 to enter the 1st optical fiber device 9 through a projection-side optical fiber 7. The incident light is filtered by the device 9, which transmits a component of the wavelength lambda1 in the light and reflects a component of the wavelength lambda2 that the light contains slightly. The reflected light with the wavelength lambda2 is converged by the 3rd lens 5 to enter an optical device 10 through a projection-side optical fiber 8. Its reflected light is filtered by the device 10, which transmits the contained component with the wavelength lambda1, thus improving the crosstalk characteristics.

Abstract: PURPOSE:To prevent correct recording data from being unable to be reproduced by changing the detecting sensitivity of a tracking abnormality detecting means for generating a control signal for moving an optical head in the tracking direction in response to an operation mode. CONSTITUTION:A summational output of photoelectric transducing elements 1a and 1b is monitored by a summing amplifier 8, and when the sum output is more than a prescribed value, an abnormality signal Sh for indicating a tracking directional abnormality is outputted by an autotracking abnormality detector 10, and the optical head is moved by a drive means in the tracking direction based on said signal.

Title: Electromagnetic vibrator
Inventor: BAN ITSUKI
IPC: H02K11/00
Filed: 1990-08-17
Abstract: PURPOSE:To keep the flat structure while eliminating a weak point of the short life and doing away with noise to be made by a commutator and by a brush filling one of the spaces of the vibrator with non-magnetic substance having weight. CONSTITUTION:A circular plastic magnet 5 is so magnetized that four 90-degree areas 5a, 5b, 5c and 5d may become either of the N or S magnetic pole. At that time, any two adjacent magnetic poles do not have the same polarity. Between the magnetic poles 5a and 5b, a square space 21 is made. This square space 21 is filled with substance having a large specific gravity, such as lead, as shown by a dotted area 21. When an armature coil is placed at the center of each 90-degree area, a Hall element 11a is opposed to the boundary area between the N and S magnetic poles which are located outside the N and S magnetic poles 5a-5d and are magnetized to the same phase with the magnetic poles 5a-5d. Since the space 21a which is shown by the dotted area 21 is filled with the substance having weight, vibration is caused with rotation of a magnet rotor 5. Consequently, this device works as an electromagnetic vibrator effectively.

Title: Storage device
Inventor: GO KENJI
IPC: E04H6/06
Filed: 1993-08-31
Abstract: PURPOSE:To smoothly shift a stored object onto a mount base and reduce the installation area to the utmost. CONSTITUTION:A pallet 24 is liftably arranged among two pairs of front and rear stanchions 4A, 4B, 5A, 5B. The pallet 24 is suspended and supported by chains 8a, 8b between the front stanchions 4A, 5A and between the rear stanchions 4B, 5B.

Filed: 1988-08-30
Abstract: PURPOSE:To prevent any congestion from being caused in the inside of a speech path by controlling the state of input information inputted to a buffer memory even against a traffic having a burst property as in the case of data communication. CONSTITUTION:An output terminal state detection means STij detects the state at every output terminal of a self routing switch Sij and a congestion state detection means CCi detects the congestion state based on the result of detection of the output terminal state detection means STij. Furthermore, a control means Gij controls the state of inputting input information based on the result of the detection of the congestion state detection means CCi. The congestion state at every output terminal of the self routing switch Sij is detected by the congestion state detection means CCi from the state of the output terminal state detection means STij and the control means Gij controls the state inputting the input information in response to the result of detection by the congestion state detection means CCi. Thus, no congestion can take place in the inside of the channel.

Title: High speed signal multiplexer
Inventor: MOTOIKE KOICHI
IPC: H04J3/04
Filed: 1990-08-20
Abstract: PURPOSE:To widen an operation margin at a high frequency band by providing a control means latching an inputted data to a latch means to the multiplexer when the data latched by the latch means differs from the data fed to the latch means. CONSTITUTION:Exclusive OR circuits 140-143 in a latch section 11 compare a data latched in flip-flop circuits 130-133 with a data fed to input terminals 150-153 and when the data are different, the data fed to the input terminals 150-153 is latched by a relevant D flip-flop circuit. A data selection section 12 extracts a data latched in the latch section 11 sequentially synchronously with a clock signal CK. Since the data changing asynchronously with the clock signal is surely latched by the latch means, the operation margin at a high frequency band is expanded and the operation reliability is improved.
