Inventor: AWATA YASUHEI
IPC: D01F9/22
Filed: 1982-12-25
Abstract: PURPOSE:To produce a bulky carbon fiber sheet having improved chemical resistance, electric conductivity and strength at a low cost, by impregnating an organic fiber sheet obtained by the paper making method with a solution of an organic high polymer, and carbonizing the impregnated sheet in an inert atmosphere under heating. CONSTITUTION:70-95pts.wt. one or more organic fibers selected from regenerated cellulose fibers and acrylonitrile fibers are mixed with 3-25pts.wt. pulp and 2-15pts.wt. paper making binder, e.g. PVA fibers, and formed into an organic fiber sheet by the paper making method. A solution of an organic high polymer, e.g. a phenolic resin, is then impregnated into the resultant organic fiber sheet, and if necessary a heat resistance improving agent, e.g. magnesium primary phosphate, is impregnated thereinto. The resultant organic fiber sheet is then ifusibilized and carbonized at >=800 deg.C in an inert atmosphere under heating to give the aimed carbon fiber sheet.

IPC: H02N6/00
Filed: 1990-08-28
Abstract: PURPOSE:To expand the applicable field of an optoelectric transducer and improve its technology by a method wherein an optical energy supplied from an optical fiber is converted into an electric energy by an electromotive force produced by light absorption of a group of photoelectric conversion elements. CONSTITUTION:If a laser beam is introduced into an optical fiber 10 and emitted into a scattering chamber 20 from an emitting opening 10a, the most part of the beam is scattered by a scattering miller 14 and, after further multiple reflections, absorbed by solar cells 18. The other parts of the beam are directly absorbed by the solar cells 18 from the emitting opening 10a or reflected by a mirror-surface reflective unit 12 and absorbed by the solar cells 18. Electric energies can be obtained in the respective solar cells 18 by electromotive forces produced by the light absorption. Particularly, as the scattered lights are almost uniformly absorbed by a plurality of the solar cells 18 and converted into electric energies and outputted, the electric energy can be far more efficiently obtained than the energy obtained by the conversion with one solar cell.

Title: Time axis expanding circuit
Inventor: TANAKA HIROMICHI
IPC: H04J3/22
Filed: 1984-10-31
Abstract: PURPOSE:To improve the detecting accuracy of a leap field by protecting missing of a control signal of the leap field due to noise during transmission. CONSTITUTION:When data is missing due to noise during transmission and a control signal detection circuit 4 cannot correctly detect or correct a leap field control signal, a counter 13 outputs no reset signal. Since the counter 13 counts up at a preset period, even when the leap field control signal is missing, the leap filed control signal is substituted to a filed to be detected. Thus, the detecting accuracy of the leap field is improved.

Title: Digital coder
Inventor: ARAZEKI TAKU
IPC: F16C33/66
Filed: 1984-10-30
Abstract: PURPOSE:To realize highly efficient signal coding by using vector quantization and combining both a signal source with a synthesis filter optimizingly at the same time. CONSTITUTION:A framing signal (x) from a buffer 10 is fed to a subtractor 160. When frame signals J, l from a control section 191 are outputted, a signal source series Sj is outputted from a signal source memory 131 and a coefficient set Al is outputted from a coefficient memory 132. A synthesis filter 150 forms a synthesis signal Yjl from the Sj and Al. A subtractor 160 calculates the difference between the Yjl and the voice (x) and an error power calculation section 170 calculates an error power Ejl. The control section 191 receiving it seeks j, l minimizing the error power Ejl while the j, l are changed. Thus, the minimum value of the error voltage Ejl is obtained, the j, l are coded and outputted via a terminal 2. Thus, highly efficient signal coding is realized.

Title: Four-wheel steering device for vehicle
Inventor: MIYOSHI AKIHIKO
IPC: B62D127/00
Filed: 1990-08-29
Abstract: PURPOSE:To prevent the occurrence of abnormal rear wheel control by detecting the failure of a vehicle speed sensor in a four-wheel steering device and stopping rear wheel steering control with a safety control means. CONSTITUTION:When a front wheel steering angle sensor 23, a vehicle speed sensor 22 and a rear wheel steering angle sensor 24 are operating properly, a control signal corresponding to a front wheel steering angle is outputted from the main control means 30 of a controller to a stepping motor driver 28, thereby performing the feedback control of a stepping motor 16 or a rear wheel steering device for controlling a rear wheel steering angle to a desired value. On the other hand, when there is any abnormality in the fluctuation state of the sensor 22 or, for example, when a vehicle speed is changing to such an excessive extent as not seen in normal steering, a sensor failure judgement part 35 judges that the sensor 22 is out of order and outputs an OFF signal to a relay 36, thereby interrupting power supply to the stepping motor 16 and keeping the rear wheel steering angle at zero.

Title: Character recognizing device
Inventor: ISHIZUKA YASUSHI
IPC: G06K9/66
Filed: 1989-09-04
Abstract: PURPOSE:To execute character recognition processing with a high recognition rate and efficiently by referring to a character group to which a recognition pertinent character belongs by a character group discriminating neural network, changing the information which is apt to be brought to erroneous recognition to a correct recogni tion result in accordance with necessity and outputting it. CONSTITUTION:A character determining part 5 stores in advance information of a character which is apt to be brought to erroneous recognition at the time of recogniz ing a character in a character recognizing part 3, based on a result of recognition of a recognition pertinent character from the character recognizing part 3 and a result of discrimination related to a recognition pertinent character from a character group discriminating neural network 4. In such a state, for instance, in the case a result of discrimination of the character group discriminating neural network 4 is a small character 1 against a fact that a first place of a result of recognition by the character recognizing part 3 is a capital character I, a small character (x) becomes a first candidate, based on the information of the stored character which is apt to be brought to erroneous recognition. In such a way, by only executing learning of the character group discriminating neural network, the character recognition processing can be executed efficiently and with a high recognition rate.
