Title: Direct light amplifier
Inventor: WATANABE SEIJI
IPC: H01S3/07
Filed: 1994-03-10
Abstract: PURPOSE:To always perform a stable amplification irrespective of the polarization state of exciting light from a light source for excitation. CONSTITUTION:Exciting light from a laser 22 for excitation is changed into unpolarized light by an unpolarized-light generation part 11, and the unpolarized light is made incident on an optical branching and-multiplexing device 23. In the optical-branching and-multiplexing device, an optical signal which is incident via an optical isolator 24 is multiplexed with the exciting light, and multiplexed light is radiated to a rare-earth-doped optical fiber 21. Since the exciting light is the unpolarized light at this time, the propagation loss of the light-branching and-multiplexing device is not changed, and the exciting light whose intensity is definite is incident on the rare-earth-doped optical fiber. The exciting light is propagated through the rare-earth-doped optical fiber, and it excites rare-earth elements. An optical signal which is propagated through the rare-earth-doped optical fiber due to an induced emission by the excited rare-earth elements is amplified, and an amplified optical signal is radiated to the outside via an optical isolator 25.

Title: Garbage treatment apparatus
Inventor: KOYAMOTO MASANORI
IPC: B09B3/00
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To surely sterilize food poisoning bacteria and at the same time to prevent deterioration of garbage treatment efficiency by installing a sterilization operation mode in which the quantity of airflow of a fan to discharge a gas in the inside of a garbage treatment tank is lowered as compared with that at the time of normal gas discharge and the inside of the garbage treatment tank is heated to a specified temperature. SOLUTION: When a sterilization operation mode is selected, a fan 34 is so controlled as to lower the quantity of airflow as compared with that at the time of deodorization-off operation (normal gas discharge operation) and, at the same time, a panel heater 51 and an auxiliary heater 30 are so controlled by control part as to heat the inside of the garbage treatment tank 1 to about 60-70 deg.C. In this case, the object garbage to be treated with which the inside of the garbage treatment tank 1 is filled is heated by the panel heater 51 and, on the other hand, the gas in the space part which is an upper part of the garbage treatment tank 1 and is not filled with the object garbage to be treated is heated by the auxiliary heater 30. Consequently, even if food poisoning bacteria such as Escherichia coil, Salmonella bacteria, etc., exist in the inside of the garbage treatment tank 1, these bacteria are sterilized because all of these bacterial are weak to heat and sterilized at about 60-70 deg.C.

Filed: 1987-02-24
Abstract: PURPOSE:To judge whether the radio wave signal from a frequency diversity radar is received before a predetermined detailed analytical processing, by providing a simultaneous input signal detection circuit and the counter counting the output from said circuit. CONSTITUTION:A simultaneous input detection circuit 10 is constituted of a large number of AND circuits 10a and one OR circuit 10b.

The OR circuit 10b outputs a simultaneous input signal '1' when either one of the circuits 10 outputs a signal '1'. A counter 11 counts the output from the circuit 10, that is, the simultaneous input signal '1' and an output line 12 outputs a count result. On the basis of this count value, the presence of possibility of previously receiving a radio wave signal from frequency diviersity radar is judged.

IPC: C08G12/12
Filed: 1982-03-15
Abstract: PURPOSE:A urea resin modified with polyethylene glycol diglycidyl ether (abbreviated to PEGE) is combined with a specific amount of butyral resin to produce the titled forming material with increase shock resistance and lowered water absorption. CONSTITUTION:Urea and PEGE are made to react and the product is made to react with formaldehyde at a molar ratio of 1.1-1.4 formaldehyde/product to prepare a modified urea resin.

Title: Communication system and data communication method
Inventor: SHIMAKAWA KAZUNORI
IPC: H04W84/12
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To simulate a state where an access request is completed by the same operation as an access operation inside a radio wave range even when a radio wave state is defective in a radio network environment and to complete many planned access requests on the spot without delaying them. SOLUTION: In the case of transmitting data, the radio wave state at present is detected on a portable information terminal side (B11) and whether or not it is a data transmittable state is checked (B12). In the case of the data transmittable state, the data are transmitted to a communicating party through a radio network (B13). In the case of an untransmittable state, a transmission processing is interrupted and the transmission processing is restarted at the time of becoming the transmittable state (B14 and B15). Thus, a transmission request from a portable information terminal to a server computer provided in an office is inputted beforehand even when the radio wave state is defective and a job is efficiently executed.

Abstract: PURPOSE: To prevent the occurrence of burning, etc., caused by the short-circuit of the wire harness of a power source section with an inexpensive constitution without impairing a power source backing-up function. CONSTITUTION: In a power unit which supplies the output of a battery 1 to loads 5-8 through a control switch 4, a normally-opened relay switch 9 is connected between the positive terminal of a battery 1 which is grounded on its negative terminal side and input-side terminal of the switch 4 and a serial circuit of a current limiting element 10 and circuit breaker 11 is connected in parallel with the switch 9. In addition, a relay driving circuit 12 which closes the switch 9 by closing the switch 4 is connected between the output-side terminal of the switch 4 and ground. Therefore, the burning of a wire harness 16 can be prevented even when the wire harness 16 is short-circuited to the input- side terminal of the switch 4, because the circuit breaker 11 becomes opened state due to a large current flowing through the limiting element 10 and circuit breaker 11.

Abstract: PURPOSE:To obtain a device having a high accuracy of detecting maximum value a correlation coefficient, by detecting an area similar to a stored image in an input image, and deriving the correlation coefficient for every picture element in the detected area. CONSTITUTION:A target image data (figure (a)) is stored in advance in an image storage device 15. For instance, when an image (figure (b)) has been inputted by an image pickup device 11, its feature is extracted by the first feature extracting circuit 14, for instance, it becomes as shown by a figure (d), and with regard to the target image data which has been stored in the image storage device 15, as well, its feature is extracted by the second feature extracting circuit 16, and this feature image becomes, for instance, as shown by a figure (c). A similar area detecting circuit 17 detects an area being similar to the target feature image on a screen of an input feature image and drives a correlation calculating circuit 13. Therefore, the correlation calculating circuit 13 derives a correlation coefficient of the input image data and the target image data at every picture element only with regard to the detected area. As a result of operation of the correlation, which has been obtained, a coordinate point for taking the maximum value is derived by a maximum value detecting circuit 18. The image pickup direction of the image pickup device 11 is controlled from the coordinate point so that the target always enters into the visual field.
