Title: Optical soliton transmission method
Inventor: YAMADA HIDEKAZU
IPC: H04B10/00
Filed: 1990-05-11
Abstract: PURPOSE:To suppress the waveform change of optical Soliton pulses to propagate them without distortion by providing an amplifying mechanism which keeps the amplitude of an amplified optical signal constant without an influence of the variance in amplitude of the input optical signal. CONSTITUTION:An electric signal is converted to an optical Soliton pulse by an electric-optical converter 1, and this pulse is propagated in an optical fiber 8 in the first stage. After this pulse is amplified by an optical amplifier 9 for the purpose of compensating the reduction of the amplitude of the optical Soliton pulse due to the light loss of the optical fiber 8, the pulse is made incident on the optical fiber 8 in the next stage. After repeat of these propagation and amplification of the optical Soliton pulse, it is converged to an electric signal by an optical-electric converter 6. An erbium (Er) added optical fiber amplifier operated in the saturation area (Er added optical amplifier) is used as the optical amplifier 9. Thus, the stable optical Soliton pulse free from the waveform change is propagated for a long distance.

Title: Hot-air circulation unit
Inventor: NAKAMURA YOSHIHARU
IPC: F24C1/00
Filed: 1985-06-06
Abstract: PURPOSE:To provide a balanced volume of hot air between those discharged through the two openings by a method wherein a reflection plate is positioned between an air blowing side and a separator and at a side opposite to the separator with a clearance being left thereagainst when the air from the air blowing part is separately heated and blown out through the two openings. CONSTITUTION:Since the air from the blower part 11 is flowed directly down from the blowing port 12 in opposition to the clearance 22 for its most portion, no presence of the reflection plate 20 causes the hot air to show the rate of hot air heated by the second portion 18 of the heater 14. With the arrangement of the reflection plate 20, the hot air is struck against this reflection plate to enable the air heated at the first portion 17 of the heater 14 i.e. the hot air blown from the first opening 2 to be increased. A length of and a fixing position of the reflection plate 20 are varied to enable an amount of hot air from the first opening 2 and the second opening 3 to be balanced at a desired ratio.

Title: Faulty area detecting device of sequence circuit
Inventor: OKUYAMA HIDENORI
IPC: G05B23/02
Filed: 1984-06-14
Abstract: PURPOSE:To obtain the data with which a faulty area can be easily discriminated by setting previously a fault pattern and detecting the coincidence between this fault pattern and an input pattern. CONSTITUTION:When a sequence action has a fault and the coincidence is secured between either one of fault patterns set previously and an input signal change pattern, a stop signal is delivered to an address counter circuit 15 from a fault pattern detecting circuit 11. Thus the writing is discontinued at and after the next step to a read/write memory circuit 16. In a write mode of the circuit 16, the address numbers are written successively at and after No.1 every time the input signal pattern changes every step. When the writing proceeds up to an address step set previously to the circuit 15, the writing order is reset to No.1 and then carried out repetitively. Thus this sequential writing system is stopped if a falut pattern is produced. Therefore a specific area where a fault occurs is recorded to the memory.

Abstract: PURPOSE:To suppress unnecessary current consumption by judging that it is unnecessary to perform the vibration-proof operation to stop the driving of a driving means at the time of fixing a device. CONSTITUTION:If the whole of the device is shaked, a relative angle corresponding to the extent of shake is generated between an outer cylinder 161 and a sensing blade 163, and the luminous flux which is emitted from a light emitting element 167 and is reflected by a reflection face 166 appears as the position change of a spot formed on the light reception face of a photodetector 168, and a signal corresponding to this variation is outputted from the photodetector 168. This output is inputted to control circuits 17a and 17b to calculate magnitude information of the vertical angle of a variable vertical angle prism required to eliminate this shake. Control circuits 17a and 17b calculate the differences between the calculated magnitude of the vertical angle and output values of photodetectors 15a and 15b and output them to coil driving circuits 18a and 18b as coil driving command signals. Circuits 18a and 18b supply the driving currents corresponding to signals to coils 8a and 8b to generate a coil driving force. The variable vertical angle prism is rotated around axes 5a and 5b by this driving force and is so deformed that the vertical angle coincides with the calculated magnitude.
