Title: Level controller
Inventor: EGURI SHIGEHARU
IPC: H04L1/00
Filed: 1986-02-20
Abstract: PURPOSE:To always find the optimum slice level to identify an input digital data (digital signal) as a code of '1' or '0' without fail, by obtaining a level correction value corresponding to the error rate of the input digital data. CONSTITUTION:An arithmetic circuit 14 finds an error rate A from A=(counter value (c))/(counter values a+c). The error rate A represents 'a rate of too low level'. Also, an arithmetic circuit 15 finds an error rate B from B=(counter value (d))/(counter values b+d). The error rate B represents 'a rate of too high'. An arithmetic circuit 16 finds a dislocation rate alpha from alpha=1-(B/A). A correction value beta (=Rx beta ) can be found with the dislocation rate alpha and a reference data R, and the correction value beta is added/subtracted on the reference value, then being supplied to a D/A converter 17. The D/A converter 17 converts the correction value beta to an analog offset voltage, then supplying it to an adder 3, and the offset voltage and the reference voltage Eref are added, then being supplied to an input terminal at the other side of a level comparator 2.

Title: Flat type solid electrolyte fuel cell and method for preventing breakage therefor
Inventor: HISHINUMA YUICHI
IPC: H01M8/12
Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To provide a solid electrolyte fuel cell prevented from breakage due to leakage of supplied gas and a breakage preventing method. SOLUTION: This solid electrolyte fuel cell 2 comprises unit cells, separators and spacers in sequential combination. A stack 4 is formed by laminating the plurality of solid electrolyte fuel cells 2, to be tightened by a predetermined pressure. Furthermore, the stack 4 includes heat insulators 10 at the periphery near a supplying passage 52 and a discharging passage 54 for the fuel gas in a predetermined thickness. The heat insulator 10 is made of fibrous ceramic, and has a heat insulating property and an adequate air permeability. That is, the heat insulator 10 fixed to the stack 4 has a property which allows fuel gas leaked from the supplying passage 52 or the like to pass with an adequate air permeable resistance. Consequently, it is possible to avoid such a danger that the leaked gas is burnt in the vicinity of the stack 4.  The leaked gas is burnt with air surrounding the stack 4 inside the heat insulator 10, so that heat is hardly transmitted to the stack 4, thereby preventing any breakage.

Title: Device for detecting contact between cutter and workpiece
Inventor: UMEHARA TOSHIYASU
IPC: B23Q17/22
Filed: 1984-02-27
Abstract: PURPOSE:To make a device simple without any consuming part and reduce a loss in time by providing a coil, which makes an induced current flow through a closed loop at the time of contact of a cutting tool with a workpiece, and a coil for detecting, and interposing a conductive liquid between a spindle and fixed members, which constitute said loop. CONSTITUTION:When a cutting tool 12 is brought in contact with a workpiece 13, an electric loop 15 is closed allowing a current (i) to flow. As a result, a starting force is generated in a secondary coil 16 due to a magnetic field, causing a current to flow, which is detected by a detector 20. Thus, the contacting condition between the cutting tool 12 and the workpiece 13 can be detected from variation in current of the secondary coil 18. Thus, since the input is made through a primary coil, only a weak current flows at the time of machining, while the secondary coil is not affected by noise, etc. on machining. Also, electric resistance in any rotary part, which may exist, can be suppressed low due to the interposed conductive liquid and, further, the lack of any consuming part such as a brush, a slip ring, etc. enables a stable detection for a long time, while the detection, which is automatically carried out, eliminates a loss in time.
