Title: Train detecting device
Inventor: MIYAJI MASAKAZU
IPC: B61L1/18
Filed: 1995-03-09
Abstract: PURPOSE: To shorten the time from when a train enters a blocking section until a train entry signal is generated without harming the train detecting capac ity. CONSTITUTION: A train detecting signal from a transmitting circuit 4 is transmitted to a rail 1 from the exit side of a blocked section T through a transmitting coil 2 and the train detecting signal is received by a receiving coil 3 at the entrance side of the blocked section T. If a level examination of the train detecting signal level received conducted by a train detecting first level examination circuit 6 and a train entry detecting second level examination circuit 7 is found below the respective threshold values, a train on-rail detecting signal is generated by dropping a relay 8 by the first level examination circuit 6 and a train entry detecting signal is outputted from the second level examination circuit 7 to the transmitting circuit 4.  The threshold of the first level examination circuit and that of the second level examination circuit are set higher on the second level examination circuit side.

Abstract: PURPOSE:To contrive to reduce cost of a semiconductor device, and to generate no deterioration of bonding strength by a method wherein the inside electrode of the device is made to have the three layer construction of Al - a diffusion preventing metal - Al, and a silver ball is thermocompression bonded to the part thereof. CONSTITUTION:The inside electrode of a semiconductor device is made to have the three layer construction of Al 2-a diffusion checking metal 6-Al 2, and a silver ball 1 is thermocompression bonded to the part thereof. Accordingly, a condition to make silver 6 and Si dioxide 3 to come in contact directly can be checked. As the metal 6, any metal to make no solid solution with silver at least at the temperature of 400 deg.C or less, and moreover having favorable adhesion with Al is favorable. By constructing the semiconductor device in such a way, the Al 2 of the uppermost layer diffuses in the silver ball 1, while diffusion of silver into the Al of the lowest stage and into the copper of the middle layer are hardly generated. Therefore, the value of bonding strength is not changed from the value directly after bonding, and bonding of high reliability can be realized.

Title: Phase locked loop circuit
Inventor: SATO HIDEO
IPC: H03L7/093
Filed: 1987-03-06
Abstract: PURPOSE:To attain frequency ripple reduction of an output signal, excellent response and jitter suppression by providing a smoothing filter separately from a loop filter in a phase locked loop circuit to supply a current without containing ripple to the loop filter. CONSTITUTION:A phase comparator PD detects a phase difference of inputs D1, D2 and a difference in the pulse width of pulses T1, T2 and a pulse T3 not superimposed with the pulses T1, T2 is outputted. A smoothing filter TI receives the pulses T1-T3 to output a current proportional to the time differ ence of pulse widths T'1, T'2. The capacitor CF and the resistor RF connected in series between the output of the filter TI and ground constitute a loop filter. The output f0 of the voltage controlled oscillator VCO is supplied to the phase comparator PD as an input D2 via the counter and the input signal fi is used as the input D1. Through the constitution above the circuit acts like making the frequency and phase coincident. Since the filter TI has not output ripple regardless of high response, no ripple exists in the f0 and since the loop charac teristic is unchanged by the TI, jitter is not increased and stable PLL with high accuracy is realized.

Title: Specimen rotating apparatus in charged particle beam apparatus
Inventor: KIMURA ATSUSHI
IPC: H01J37/20
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To observe a specimen at high magnification by attaching one or a plurality of vibration removing members to a wire and bringing the vibration removing members constantly into contact with a holder holding member while moving the vibration removing members with the movement of the wire. SOLUTION: Vibration removing members 33 are inserted at two positions between a specimen holder 22 of a wire 26 and a driving mechanism and the specimen holder 22 is rotated by the movement of the wire 26. The vibration removing members 33 are like a button and penetrated in the center with a wire 26 and fixed by an adhesive or the like. Moreover, the vibration removing members 33 have a sufficient size just as to be pressure connected with both or either one of the bottom part 21b and a wall part 21c of a groove part of a holder holding member 21. The magnitude of a vibration transmitted through the wire 26 is attenuated due to significant cross section surface change at the vibration removing members 33 in the vibration transmission route and since the vibration removing members 33 are pressure connected with the holder holding member 21, the vibration is transmitted to the holder holding member 21 and attenuated. As a result, this apparatus is made thin and the mechanism is simplified.

Filed: 1992-03-09
Abstract: PURPOSE:To obtain a stable contact resistance and a high electromigration resistivity by surrounding the upper and lower surfaces of an embedded tungsten with a tungsten film that is produced by a sputtering method. CONSTITUTION:An Al-Si-Cu film 4 sandwiched between tungsten films 3 and 5 is patterned onto a silicon oxide film 2, so that a lower interconnection layer is produced. Next, an interlayer dielectric film 6 is formed over the lower interconnection layer. An interlayer connection hole is formed at a specified location on the lower interconnection layer, and tungsten 7 is embedded in this interlayer insulating hole. Finally, an Al-Si-Cu film 9 sandwiched between tungsten films 8 and 10 is patterned, so that an upper interconnection layer is produced. Thereby, the production of any fluoride of aluminium during a selective W-CVD growth is prevented, and hence a stable contact resistance of the upper and lower interconnections is obtained. Also, when a current flows from the upper interconnection to the lower interconnection, the presence of the tungsten film 8 prevents an open-failure from occurring even if a void 11 is produced at a lower part of the upper interconnection.
