Title: Power transmission shaft
Inventor: NAKAJIMA TATSUO
IPC: B32B1/08
Filed: 1999-08-05
Abstract: PROBLEM TO BE SOLVED: To provide a lightweight and high-rigidity power transmission shaft having high connecting strength at a low cost by inserting an FRP pipe into a metal pipe to form the power transmission shaft connected a metal joint element and the metal pipe. SOLUTION: An FRP pipe 20A is inserted into with a metal pipe 10 to form a composite shaft as a power transmission shaft. Since a metal is used for the connection portion as the shaft end section of the composite shaft, power can be transmitted with sufficient endurance strength even when large shearing occurs. The FRP pipe 20A has a slit 21, thus facilitating the assembling when it is inserted into the metal pipe 10. The slit width W is preferably set to 0.01-40% of the outer periphery of the FRP pipe 20A in the natural state. The FRP pipe 20A is preferably combined and laminated with FRP layers having the fiber orientation angles of 0 deg. and ±45 deg. against the axial direction of the metal pipe 10.

Title: Magnetic tape running device
Inventor: HASEGAWA KYOICHI
IPC: G11B15/60
Filed: 1986-09-19
Abstract: PURPOSE:To prevent the longitudinal vibration of a magnetic tape by providing a magnetic tape running guide coupled mechanically with a laminated type piezoelectric actuator and varying the drive voltage of the actuator so as to vary the tilt between the magnetic head tape running face and the magnetic tape running guide freely. CONSTITUTION:In applying the drive voltage to the laminated type piezoelectric actuators 2, 3 so as to allow the magnetic tape running guide 6 to be displaced in the direction of arrows A, A', a tilt angle theta is produced between the magnetic head 1 and the magnetic tape running guide 6. A force in the direction of arrow B is exerted onto the magnetic tape 12 in running by the tilt angle theta and the magnetic tape moves under the lower side of the magnetic head 1. In applying a voltage in opposite polarity to the drive voltage, the magnetic tape 12 moves to the upper side of the magnetic head. Moreover, in applying the drive voltage to the laminated type piezoelectric actuators 2, 3 and 4, 5 so as to allow the magnetic tape guides 6, 7 to move toward the arrows A, C respectively, the magnetic tape 12 receives a force in the direction of arrows B, D and runs at an optional position of the magnetic head 1. Thus, in applying the drive voltage by a tracking error signal, the longitudinal vibration due to the error of the magnetic tape width is prevented.

Title: Protective device for system interconnection
Inventor: KOZUKI RYOSUKE
IPC: H02J3/38
Filed: 1994-09-19
Abstract: PURPOSE: To detect the single operation of a generator upon occurrence of failure on the system side in a nonutility generator when a reverse power flow is present by detecting power interruption on the system side based on the comparison results of a voltage passed through an active filter circuit and a set voltage. CONSTITUTION: A nonutility power generation facility 1a and a nonutility power generation facility 1b for other consumer generate power from respective generators 11a. The load 15a of each nonutility power generation facility is fed with power from the generator 11a and the system side or power is fed from each generator 11a to the load 15a and the system side during reverse power flow operation. When a circuit breaker 5 on the system side is opened due to some cause, the nonutility power generation facility is operated independently. The voltage on the private system bus contains a frequency component generated from a signal generator 17a which is detected through an active filter in a protective unit 18a thus detecting power interruption on the system side. Consequently, the circuit breaker at a power receiving point can be opened quickly.

Title: Formation of polycrystalline silicon film
Inventor: KUWABARA TAKASHI
IPC: H01L21/20
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming, on a glass substrate, a polycrystalline silicon film which has little unevenness on its surface and little attachment of impurities. SOLUTION: As amorphous silicon film 2 is formed on a glass substrate 1, and etched into a specified shape. Thereafter, the silicon film 2 is annealed and made into a polycrystalline silicon film 3. Since the silicon crystals grow also in the transverse direction of the substrate, there occurs hardly conflict in the crystal growth, and therefore the surface of the polycrystalline silicon film 3 is flattened. Hydrogen in the film is easily detached, so impurities can be prevented from sticking on the surface of the polycrystalline silicon film 3 by forming a cap film 10.

Title: Transmission system and transmitter
Inventor: AKAMINE MASAMI
IPC: H04B14/04
Filed: 1988-09-08
Abstract: PURPOSE:To prevent the locking into the communication disable state due to difference decoding system between a coder and a decoder by assingning one of m-set of codes as an inhibition code and allowing the decoder to detect a faulty state through the detection of the inhibition code thereby immediately attaining automatic restoration to the normal state. CONSTITUTION:Let the quantization level of voice or nonvoice coder 1 and 2 be (m) and let the quantization level of nonvoice or voice coder 1 and decoder 2 be (m-1), then one level code is assigned to the inhibition code and it is used to detect a voice or nonvoice signal. Thus, even if the mode of the coder 1 and the decoder 2 differs, the normal state restoration is quickly realized by using the inhibition code included in the signal. Then the locking into the circuit disable state is prevented.

Title: Automatic gain control circuit
Inventor: FUKUSHIMA NORIYUKI
IPC: H03H11/12
Filed: 1983-11-28
Abstract: PURPOSE:To relax the restriction of a dynamic range due to an active filter by inserting the active filter giving a frequency characteristic to an input signal after a gain control amplifier in a loop of a gain control system. CONSTITUTION:After the gain of an input chrominance signal of a television receiver is adjusted by a gain control amplifier 2, the result is led to the post- stage through the active filter 1 providing the frequency characteristic. An output of the filter 1 is given also to a detection circuit 3 and the level detecting output of the circuit 3 is given to the amplifier 2 as a gain control signal through an LPF4. Since a signal passing through the filter 1 is limited to a prescribed amplitude by the amplifier 2, the dynamic range of the filter 1 is small enough to allow the filter 1 to be formed with a building block of an RC element and an active element. The change in the filter characteristic due to variation in constants of the components of the filter 1 is corrected by negative feedback.
