In addition, the first and second external electrodes 14 and 16 are respectively connected to the end faces of the substrates 4 where the members 10 are formed and end faces of the electrodes 8 where the member 12 are provided. Since the silicon oxide forming the dielectric films 6 is compact and high in withstand voltage, the withstand voltage of this capacitor is improved. Moreover, since the substrate 4 are piled up, the capacitance of this capacitor is multiplied and, in addition, since the members 10 and 12 are used for coating, the electrode connecting process can be carried out easily. Therefore, a capacitor having large capacitance and high withstand voltage can be manufactured easily.

IPC: H04M11/00
Filed: 1985-07-19
Abstract: PURPOSE:To improve operability and reliability at line switching by providing the 2nd switching means connecting selectively a detection means to a power supply and a subscriber line through other path than a path having the 1st switching means. CONSTITUTION:In making a call from a network controller 1, a controller 2 releases a relay Y to apply branch connection of a NCU 1 and a telephone set to a subscriber line and the telephone set is hooked off, then a loop current flows to a photodiode PD of a optical coupling element HSO or HS 1 and a photo transistor PTR of the HS 0 or HS 1 is conducted. The controller 2 identified off-hook of the telephone set when an input point HS changes from a +V level to a groundlevel and then releases a relay X. Since the relay Y is released earlier, when the subscriber line is switched from the NCU and a MODEM 1 to the telephone set, no line open state is caused. In applying data communication from the NCU and the MODEM 1 completing the taking, the relay Y is activated after the relay X is operated, then the open state of the subscriber line is avoided.

IPC: H01L21/027
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To control the position of a driven object easily and with high precision. SOLUTION: If a current is applied to a coil 52 fixed to a 2nd member 50, an attractive force is developed between the coil 52 and one permanent magnet 46 and a repulsive force is developed between the coil 52 and the other permanent magnet 48, and the 2nd member 50 is vertically driven relative to a 1st member 44. In this case, as the relationship between the repulsive force and the distance between the coil and the permanent magnet and the relationship between the attractive force and the distance between the coil and the permanent magnet exhibit characteristics opposite to each other, the respective nonlinear changes of the repulsive force and the attractive force cancel each other and a force which has the high linearity to the change of a current is developed regardless of the relative positions of the coil 52 to the permanent magnets 46 and 48.  With this constitution, as long as the current applied to the coil 52 is constant, a driven object 20 to which the 2nd member 50 is attached is driven by an approximately constant force relative to a stage 19 to which the 1st member 44 is fixed.

Abstract: PURPOSE:To reduce the memory amount of the coding code by adding the bit of 1 or 0 to the code showing the relative position error for the changing point of the picture information until the amount reaches the general digit number of the code memorized in the memory. CONSTITUTION:Both the data of under the fixed digit and the data showing the general digit number of the code among the bits of the code indicating the relative position error between the picture information changing point of the binary coded picture signal and its preceding picture informaton changing point are memorized previously into MH (modified Hoffman) table ROM7. Then the picture signals equivalent to one line memorized in RAM5 are read out, the information changing point is read out by the changing point detector 14, and the run length up to the precedig changing point is counted by counter 6. The data showing the general digit number is read out of ROM7 against the counter code of counter 6. The bit of 1 or 0 is added to the reading code via detector 8 or inserter 9 until the general bit number is obtained for transmission in the form of the transmission data. As a result, the memory amount of the coding code can be reduced, thus simplifying the coding code can be reduced, thus simplifying the coding process.
