Title: Method for improved low-pressure chemical vapor deposition for deposition of titanium nitride thin film provided with stable and low electric conductivity
Inventor: GAATEEJIYU ESU SANDEYUU
IPC: C30B29/38
Filed: 1992-09-07
Abstract: PURPOSE: To provide a stable, low electric resistivity and to form a thin film which is conformal in hardness by introducing a substrate into a chemical vapor-deposition chamber, purging oxidation in the chamber, forming a flow of a mixture of gaseous ammonia and titanium-metal organic compound having a specific flow-velocity ratio and heating the substrate. CONSTITUTION: Deposition is performed in a chamber, wherein the pressure is reduced to 0.1-2Torr. As a precursor, ammonia and tetrakis (dimethylamide) titanium are used. A flow velocity is maintained at 30 times or more of the ammonia flow velocity in the depositing chamber and the flow velocity of the tetrakis (dimethylamide) titanium. Furthermore, a substrate is heated to at least 200 deg.C. Thus, an obtained TiN thin film has a low bulk electric resistivity and has a constant resistance with respect to in time passage, even when exposed in an oxidizing atmosphere.

Filed: 1988-10-19
Abstract: PURPOSE:To constantly stably hold a table to an external exciting force by measuring displacement due to the vibration of the table by the use of laser light and exciting the table to a direction for cancelling the displacement automatically. CONSTITUTION:A laser oscillator 10 for irradiating laser light on an article 1 to be measured on a table 2 is disposed thereon. The laser light 11 produced by this laser oscillator 10 is separated by a half mirror 8 and inputted to a detecting and amplifying part 12. The detecting and amplifying part 12 calculates the displacement of the table 2 from a phase difference between the progressing wave and the reflected wave of the laser light 11 and feeds the signal of a negative phase synchronous with the displacement to a piezoelectric element 3 through electrodes 4, 5. The piezoelectric element 3 generates mechanical distortion according to the fed signal and vertically moves the displacement of the table 2 to a direction for cancelling it. Thus, the table 2 is stabilized to an external exciting force.

Title: Variable superconducting delay line
Inventor: MIURA SADAHIKO
IPC: H01L39/22
Filed: 1994-10-27
Abstract: PURPOSE: To obtain the variable superconducting delay line with a low insertion loss and a large phase shift and a circuit utilizing the delay line. CONSTITUTION: A superconducting strip 1 is formed on a substrate made of a low dielectric loss material 5 with a superconducting ground 3 on its rear side. A DC block capacitor 4, an RF input output terminal 7 and an impedance matching device 8 are provided to the substrate. The low dielectric loss material 5 under the strip 1 and in the vicinity is replaced with a ferroelectric material 2. A DC voltage is applied between the strip 1 and the ground 3 to change a dielectric constant of the ferroelectric material 2 thereby controlling a phase. Since a superconducting material is used for the strip 1 onto which a current is concentrated, a high frequency loss of an electrode is very low.  Furthermore, the phase is controlled by changing the dielectric constant of the ferroelectric material being an intermediate layer inserted between the conductors and the property of the superconducting material is not used. Thus, problems such as the element characteristic changed by temperature or no phase change is caused at a high input power are avoided and the amount of phase shift is large.

Title: Servo agc circuit for optical disk device
Inventor: OZAWA YASUYUKI
IPC: G11B7/09
Filed: 1988-10-21
Abstract: PURPOSE:To simplify the circuit configuration of the title circuit and to eliminate the necessity of offset voltage adjustment by providing switch circuits to each division of a photodetector between the photodetector and subtractor and performing a damping operation before a difference is calculated by the subtractor. CONSTITUTION:A photodetector 20 divides reflected light from a medium into plural parts. A subtractor 21 obtains a servo error signal by performing subtraction on each divided output of the detector 20. An adder circuit 22 adds each divided output of the detector 20 to each other. Switch circuits 24 are switched to each other by the pulse output of a pulse generation circuit 23 and the switching output of the circuit 24 is averaged. In the case of writing time when the quantity of the reflected light increases is started, the output of the circuit 22 becomes larger than a target value and the duty ratio of the output pulse of the circuit 23 becomes smaller. Therefore, the damping factor of the circuit 24 increases and the servo gain can be made constant, because the circuit 22 is controlled so that the output of the circuit 22 can be dropped. In such a case, no bipolar circuit is required for the subtractor 21. Moreover, it is not necessary to generate an offset voltage, since digital operations by means of PWN control are performed.

Abstract: PURPOSE:To obtain a sound with feeling of spread by eliminating a sound signal from a signal of a channel on which no listening of a sound multiplex signal is desired and adding it to a desired channel. CONSTITUTION:A main sound and a sub-sound are demodulated respectively by a main sound demodulator 1 and a sub-sound demodulator 2 from an inputted sound multiplex signal. Switches SW1, SW2 are interlocked and either the main sound or the sub-sound is selected. Suppose that the switch SW2 is thrown on the position of B' and the main sound is selected. Since the switch SW1 is thrown to the position of B, the sound is eliminated by a filter 3 from the sub sound not selected in this case. The filter 3 is a band eliminating filter or a simple high pass filter, which attenuates a signal of a frequency of about several hundreds Hz. Then the signal from which the sound is eliminated is added to the main sound at an adder circuit.

Abstract: PURPOSE:To offer a synchronous rotation control method between a main spindle and a sub-spindle in a numerically controlled lathe which can deliver not only round materials but also square materials by conforming the phases of the main spindle and sub-spindle at the time of delivering a workpiece from the main spindle to the sub-spindle during rotation. CONSTITUTION:In order to conform the phase difference between a main spindle 1 and a sub-spindle 7, the position PP of the sub-spindle 7 is detected based on the position detecting signal PPS of a position detector 11 by a sub-spindle position detecting portion 126.
