Title: Formation of thin film
Inventor: SAWABE ATSUHITO
IPC: H01L21/203
Filed: 1993-09-14
Abstract: PURPOSE:To form films to fill the narrow grooves on a substrate at a high speed and to obtain the high-quality thin films by applying an electric field of a prescribed direction to ionized raw material particles to move these particles in parallel with the electric field direction and allowing the particles to progress in parallel with the flanks of the narrow grooves. CONSTITUTION:Inert gaseous ions are brought into collision against a target 7 arranged in a discharge chamber 3 to release the raw material particles. The particles are irradiated with electrons from an electron source 11, by which the raw material particles are ionized. The particle flow is then changed and moved in a direction perpendicular to the surface of the substrate 9 by the electric field generated by an acceleration electrode 13. The particle flow is made to arrive perpendicularly at the thin film forming surface of the substrate 9. The films to fill the narrow grooves are thus formed at a high speed by the particle flow having the unified directivity.

Title: Data transmission system
Inventor: TAKATSU KAZUNORI
IPC: H04L27/00
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To realize flexible data communication by changing the number of bits mapped to a signal point. SOLUTION: An incidence probability predict section 12 receiving a symbol stream from a data source 11 of a transmitter estimates incidence probability based on the incidence frequency of symbols and reports it to an area division section 13. The area division section 13 conducts area division bit share based on the incidence probability of the symbol and reports it to a mapping section 14. The mapping section 14 selects an area in response to the symbol stream from the data source from the area divided by the area division section and sends its representative point to a modulation section 15 as a signal point, from which the signal is sent.  A receiver uses a demodulation section 21 to demodulate waveform data and converts the data into a signal point, a Demapping section 22 inputs a symbol stream corresponding to the area including this signal point to an incidence probability predict section 23, which predicts the incidence probability. As the area division section 24 uses the probability to conduct area division and the result is used by the Demapping section 22.

Title: Method for pulling-in focus servo
Inventor: KAWAMURA KATSUMI
IPC: G11B7/09
Filed: 1988-09-13
Abstract: PURPOSE:To shorten starting time and to stably pull-in a focus servo by moving an objective lens at a high speed in a recording surface direction, after that switching the high speed into a low speed, and closing a focus servo loop based on a focus error signal level to be obtained at the time of low-speed moving. CONSTITUTION:After the objective lens is separated from a disk recording surface at a prescribed distance in the open state of the focus servo loop, first, the objective lens is moved at the large first speed (the high speed) to be determined with constant current sources 11 and 12 in the direction to approach to the recording surface. Continuously, the moving speed is switched into the small second speed (the low speed) to be determined only by the constant current source 12 in prescribed timing, and the focus servo loop is made into a closed state based on the focus error signal level to be obtained at the time of the moving at this low speed. Thus, the starting time necessary for starting a system can be widely shortened, and since the moving speed of the objective lens is the low speed at a point where the servo loop is to be closed, pulling in can be stably executed.

Title: Formed gear
Inventor: TAKEMORI HIROAKI
IPC: F16H55/14
Filed: 1990-08-30
Abstract: PURPOSE:To prevent the generation of a resonance sound, vibration and noise of a base, and periodic vibration and noise by forming a ring damper part from a synthetic resin softer than a disc gear body in the state where it is charged in a circular space between an inside disc part and a ring tooth form part. CONSTITUTION:When a partner gear 60 is rotated by a drive source, the driving force is transmitted from the partner gear 60 to a formed gear 10 through the gearing part of tooth form parts 13, 26 to rotate the formed gear 10. In this driving force transmission, a gearing shock and a vibration by mutual sliding are generated in both the tooth form parts 13, 26. The vibration generated in the ring tooth form part 13 is absorbed and damped by a soft resin ring damper part 21 interposed between the ring tooth form part 13 and an inside disc part 12. Thus, the ratio of the vibration transmitted to the whole formed gear 10 is sufficiently low, and a resonance sound by vibration of the whole formed gear 10 is hardly generated. By the same reason, the ratio of the vibration transmitted to a base 70 is also sufficiently low, and vibration and noise are hardly generated in the base 7.

Title: Filter device
Inventor: SUZUKI SHINICHI
IPC: H03H19/00
Filed: 1984-10-31
Abstract: PURPOSE:To obtain a variable pass band characteristic filter device acting excellently against a broad band input by providing a low pass filter having a cut-off frequency lower than the internal clock frequency of a switched capacitor filter (SCF) to the pre-stage of the SCF having a required characteristic. CONSTITUTION:The cut-off frequency of a switched capacitor low pass filter LPF4 changes depending on the clock frequency fed from a frequency divider 5. The frequency divider 5 frequency-divides the 1st clock frequency fed from a frequency divider 2 to a prescribed ratio to generate the 2nd clock frequency signal. Through the constitution above, the 1st clock fed from a clock oscillator 1 is changed to shift the center frequency of an LPF3, then the cut-off frequency fc of the LPF4 is shifted accordingly. Since a signal of output frequency f3 of the LPF4 produced by an input frequency f4 is apart from the cut-of frequency f1 by 2-3 octaves, the gain is attenuated by -24dB--36dB by the LPF3.
