Title: Method for detecting water tree deterioration of power cable
Inventor: TSUNODA YOSHIO
IPC: G01R31/12
Filed: 1989-07-19
Abstract: PURPOSE:To accurately detect water tree deterioration by removing the effect of a local battery by monitoring the transmission voltage of a power cable and detecting the water tree deterioration from the change degree of DC component quantity accompanying the change of the transmission voltage. CONSTITUTION:A voltage measuring device 3 for monitoring the transmission voltage to a power cable 1 is connected between a conductor L and the earth. In a cable wherein no water tree deterioration is present, there is no change in the DC component quantity measured by a measuring device 2 even when transmission voltage changes. However, in a cable wherein water tree deterioration is present, the DC component quantity is changed corresponding to deterioration and, therefore, the value of the measuring device 3 and the DC component quantity of the measuring device obtained when the transmission voltage boosts or drops by the load change of one day are measured and the measured values are compared with each other. By this method, even when a local battery is generated between an anti-corrosion layer and the earth, water tree deterioration can be accurately detected.

Title: Voice transmission system
Inventor: KURIHARA HIDEAKI
IPC: H04J3/17
Filed: 1992-07-16
Abstract: PURPOSE:To send a voice signal safely and surely by using a voice information extract section to extract voice information such as a pitch and a period to discriminate a voice signal or a non-voice signal and selecting voice decoding data as an output when the voiced block is discriminated. CONSTITUTION:When a voice information extract section 4 detects a prepattern or a post pattern from an output signal of a voice decoder 1, the section 4 sends a switching control signal to a changeover device 3 so that an output signal of the voice decoder 1 or a background noise from a background noise generator 2 is selected and outputted. However, when no pre-pattern or a post pattern is detected due to a line fault or the like, the voice information extract section 4 extracts voice information such as a pitch or a period from an output signal or an input signal of the voice decoder 1 to discriminate the voiced block or the non-voiced block and sends the switching control signal to the changeover device 3. The changeover device 3 selectively outputs a digital voice signal from the voice decoder 1 similarly to the case with the detection of the pre-pattern when the result of discrimination indicates the voiced block and selectively outputs a background noise when the result of discrimination indicates the non-voiced block.

Title: Objective optical system for endoscope
Inventor: TAKAHASHI SUSUMU
IPC: A61B1/00
Filed: 1987-07-29
Abstract: PURPOSE:To shorten the overall length of an objective optical system by using a material which absorbs light of the oscillation wavelength of a YAG laser to form at least one of optical elements in a front group and rear group and forming interference films on the joint faces of the optical element and/or the exist face of the rear group. CONSTITUTION:At least one piece of the optical elements in the front group and the rear group is formed of the material which absorbs the light of the oscillation wavelength of the YAG laser and the interference films 16, 17 which reflect the light of the oscillation wavelength of the YAG laser are formed on the joint faces in the front group and the rear group and/or the exit face of the rear group and, therefore, IR light can be sufficiently removed without having a filter space. The overall length is consequently short and the size is small. Since an IR absorption type cut filter 15 for adjusting visual sensitivity is disposed in the position behind a planoconvex lens 14 which is the rear side lens, i.e., the position where the main rays are parallel, the colors within the visual field are uniformized.
