Title: Abnormality detecting device for bearing
Inventor: NISHIMOTO SHIGETO
IPC: G01M13/04
Filed: 1990-05-29
Abstract: PURPOSE:To improve the accuracy of abnormality detection by dividing the actual frequency of acoustic emission AE which differs with positions by the logical frequency of AE generation by the positions and thus finding AE generation probability, and comparing and AE generation probability with a single threshold value. CONSTITUTION:When an AE sensor 1 detects AE from the bearing and outputs an AE signal, a BPF 3 removes its noise and after envelope detection 5, a comparator 6 compares the signal with a threshold value and outputs a signal indicating that the signal exceeds the threshold value to a computer 7 when so. The computer 7 calculates the period of the AE signal and totalizes the frequency of the generation of the AE signal in each generation period. The totalized frequencies of generation by generation periods are divided by the logical frequencies of AE generation by the positions corresponding to the generation periods to calculate the probability of AE generation by the positions. The AE generation probability is compared with the single threshold value and when the AE generation probability in a generation period exceeds the threshold value, abnormality of the bearing is decided and a warning is outputted. It can be judged which of the inner ring, rolling body, and outer ring damages from the generation period where the AE generation probability exceeds the threshold value.

IPC: H01S3/108
Filed: 1992-05-29
Abstract: PURPOSE:To enlarge the frequency range of signal beams to be splitted. CONSTITUTION:The plural signal beams of multiple frequencies and locally oscillated beams are inputted to a non-linear optical material 28, and the frequency of each signal beam is converted to the differential frequency of the signal beam and the locally osicllated beam. Afterwards, these plural signal beams are inputted to an optical filter 30, and the desire signal beam to be splitted is selectively splitted. In this case, the frequency at the time of inputting the locally osicllated beams to the non-linear optical material is variably controlled while fixing the splitting frequency of the optical filter 30, and the converted frequency of the signal beam desired to be splitted among these plural signal beams is made equal to the splitting frequency of the optical filter. Thus, the purpose can be achieved by splitting the signal beams.

Inventor: SATO HIROYUKI
IPC: G01C21/00
Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To prevent a present position from being displayed at positions at intervals. SOLUTION: When a present position received from a GPS receiver is isolated from a present position measured from a sensor output more than or equal to a specified threshold value, a processor 1 selects the present position obtained by the GPS receiver as the final present position. When the isolation is less than the threshold value, the processor 1 selects the measured present position as the final present position. In the case that a present position on a road is obtained by a map matching process, the obtained present position on a road is set as the final present position, only when the obtained position is not isolated more than the specified threshold value.

IPC: H04M9/00
Filed: 1989-06-01
Abstract: PURPOSE:To allow a slave set at the outside of a gatedoor to recognize the result of detection of a sensor such as the security provided to each part a house by decoding a code signal sent to a television camera of the slave set and outputting the result of detection of each sensor from a speaker of the slave set according to a decoded instruction. CONSTITUTION:A call button 12 is depressed to turn on a television camera 9 and a transmitter 13 sends a signal to a gatedoor slave set 8. The code signal is being decoded while a CPU 18 collates a ROM 18a in which the registered code is stored. For example, when an instruction is an instruction to a gas sensor 5a, the state is sensed and when no fault exists, the CPU 18 controls a voice synthesis section to form a synthesized voice of 'no fault' and it is sounded from a speaker 10 of the slave set 8. Thus, the gatedoor slave set simply recognizes each sensor state by using a television intercom.

IPC: H04N1/04
Filed: 1985-06-26
Abstract: PURPOSE:To attain excellent color reading with a simple construction by setting each filter to an arc shape and the shape of an opening part between filters to a shading correction shape. CONSTITUTION:Respective filters 19a-19c are made in arc shapes, coaxially arranged with a rotating spindle 20 as a center and are generally made in approximately a cylindrical shape. The ends of the filters 19a-19c are bent in a drumlike shape so as to form, and the shapes of the opening parts 22a-22c formed between the filters 19a-19c are set in shading correction shapes. Namely the opening parts 22a-22c are set so that their centers are narrow in width sand become gradually wider as the width go to both sides. Thus it is unnecessary that an exclusively used shading correction plate is separately installed, and the excellent color reading can be possible at a moderate cost with the simple construction.
