Title: Method and device for inserting watermark into music information and its program recording medium
Inventor: MATSUURA YUMIKO
IPC: G10L19/018
Filed: 1999-05-25
Abstract: PROBLEM TO BE SOLVED: To make noise caused by inserting a watermark less conspicuous. SOLUTION: In the watermark insertion method, a watermark inserting position is randomly determined with respect to musical sound signals. If one of the binary watermark information is '1', the musical sounds from an insertion position Pn to Xmsec are duplicated and made into as insertion signals. If the information is '0', the musical sounds from Pn+X to Xmsec are duplicated and inserted to an insertion position Pn as insertion signals. Note that before inserting the signals, the musical sounds from the position Pn to Xmsec are duplicated, the sound pressure is increased for 5 dB to produce relative signals, the signals are delayed for Ymsec, that is an allowable delay for the perception characteristic, and the signals are inserted into the musical sounds. Thus, the insertion signals are suppressed hearingwise by the relative signals.

Title: Solid electrolyte fuel cell
Inventor: IPPONMATSU MASAMICHI
IPC: H01M8/04
Filed: 1990-06-01
Abstract: PURPOSE:To enhance the performance of a solid electrolyte fuel cell by feeding oxygen-enriched air to the side of an air electrode and supplying reformed fuel to the side of a fuel electrode, and also recycling fuel. CONSTITUTION:Oxygen-enriched air has its oxygen density raised to more than 90 capacity % by the PSA method, etc. Though the density of an air electrode is increased, diffusion resistance is lowered to reduce inner resistance of the air electrode so as to enhance the output density of a solid electrolyte fuel cell. Raw material hydrocarbon and recycle gas are mixed together and steam reformed. Thus the running cost of the cell is reduced, and at the entrance of a power generating portion the ratio of steam to carbon is 1.0 to 2.0 whereby power generation efficiency of the cell is enhanced. Fuel is stirred in a power generating portion and its temperature is uniformized and cooling of the cell is carried out together with recycling of fuel to prevent deterioration of the cell.

Title: Deflecting device
Inventor: IKEUCHI HIROSHI
IPC: H04N3/18
Filed: 1987-06-10
Abstract: PURPOSE:To eliminate the danger of a rare short circuit by opening a gate and supplying a fusion current when the output voltage of a rare short-circuit detecting circuit exceeds a reference value, and blowing a fuse and inhibiting a voltage from being applied to the low-voltage side coil of a flyback transformer. CONSTITUTION:When a rare short circuit is formed in a high-voltage side coil 25, an alternating current flowing through the lowvoltage side coil 23 increases. A DC voltage outputted by the rare short-circuit detecting circuit 28 also increases according to the current increase and its DC voltage value exceeds the reference value of a voltage which is given to the gate circuit 30 previously, so the gate of the gate circuit 30 is opened. Then the fusion current flows to the fuse 45 connected directly or indirectly to the low-voltage side coil 23 and the fuse 44 is blown. The blowing of this fuse 45 cuts off the input of a driving voltage to the low-voltage side coil 23. Consequently, the danger of the rare short circuit is eliminated.

Title: Clock fault detecting circuit
Inventor: MOMOI AKIRA
IPC: G06F1/04
Filed: 1987-06-12
Abstract: PURPOSE:To detect a fault of a clock distributing part and a supply part of a data processor by providing an FF for inverting an output by synchronizing with a clock pulse, and comparing the outputs of the FFs. CONSTITUTION:As for outputs F1-F3 of FFs 161-163 (in the case of using three pieces of lodical modules), the logical polarity is inverted as far as clocks A1-A3 and reference clocks C1-C3 are inputted correctly. In this case, each output of an all '0' detecting circuit 19 and an all '1' detecting circuit 20 does not coincide, and accordingly, an output of a NOR gate 21, namely, an error signal G always becomes '1'. If an abnormality is generated at the next timing and the reference clock is not inputted to the FF 162, the output F2 does not become '1', an output of the circuit 19 becomes '0', an output of the circuit 20 also becomes '0', and the error signal G becomes '0'. In such a way, a diagnostic processor 23 knows that a fault has been generated in a clock distributing part of a clock generating module 1 or a clock supply part of logical modules 101-103.

Title: Contact device of circuit breaker
Inventor: UCHIDA NAOJI
IPC: H01H77/10
Filed: 1989-06-08
Abstract: PURPOSE:To maintain the effect of a contact spring almost equal to that when a fixed contact is in a closed state, even with opening movement of the fixed contact, to obtain a big opening distance by setting the angle of inclination of a long hole such that a pin located at the lower end portion of the long hole starts to slide toward the upper end portion of the long hole when the fixed contact is rotated to some extent from its closed state against the contact spring. CONSTITUTION:When a fixed contact 3 is rotated the angle of inclination of a long hole 18 is increased as compared to when the contact is in its closed state. Frictional forces between a pin 17 and the inner peripheral face of the long hole 18 are therefore decreased and, when the fixed contact 3 is rotated to some extent the pin 17 starts to slide toward the upper end portion of the long hole 18. The pin 17 locates at the upper end portion of the long hole 18 at that moment when the fixed contact 3 finishes its opening movement. The spring force of a contact spring 15 which temporarily increases is maintained at that condition when the pin 17 starts its sliding movement, and will not increase any more. Even when the opening distance of a movable contact 4 is increased, the spring force of the contact spring is therefore maintained at a value approximating that obtained when the contact is in its closed state.
