Title: Variable phase shifter
Inventor: KAMIYA NOBUYUKI
IPC: H03H7/18
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To make a circuit small-sized by constituting the phase shifter by using an FET as a switch, switching a case wherein the whole circuit is seen as a series capacitor as a phase-leading circuit as to passing signal and a case, wherein the whole circuit is seen as a mere transmission line, and shifting a passing phase. SOLUTION: An FET 3, when applied with an on voltage at its gate, outputs a signal inputted from the drain from the source as is to enter a through state. On the basis of the phase of a high-frequency signal which is inputted to an input terminal 11 and outputted from an output terminal 12 in this state, and a gate pinch-off voltage is applied to the gate of the FET 13 next. At this time, the FET 13 goes into an on state wherein a signal cannot pass, so that the signal passes through a capacitance 14 and the high-frequency signal from the input terminal 11 is advanced in phase, based on the reference and outputted from an output terminal 12. Consequently, this shifter operates as a variable phase shifter which changes the passing phase in two ways by changing the state of the FET 13 and can be made small-sized.

Title: Waveguide high-pass filter
Inventor: KURONO MASAKAZU
IPC: H01P1/207
Filed: 1995-01-24
Abstract: PURPOSE: To prevent VSWR in the neighborhood of a passing lower limit frequency from deteriorating and to attain impedance matching in a wide frequency band area by defining the length of a cutoff waveguide at specific length. CONSTITUTION: The minor diameter side of waveguide impedance transformers 2A, 2B consisting of a 1/4-wavelength step impedance transformer is connected to both terminals of the cutoff waveguide 1, and standard waveguides 3A, 3B are connected to the major diameter side of the waveguide impedance transformers 2A, 2B. An impedance matching point can be set at a frequency not being too low below the passing lower limit frequency in which an impedance matching state may be deteriorated by setting the length of the cutoff waveguide 1 at that of (n) times 1/4 guide wave length in the lower limit frequency of a high-pass required passing frequency band area assuming (n) as an odd number. Moreover, since the worst VSWR in another passing frequency is predicted, impedance deterioration in the specific frequency of a passing area can be evaded.

Title: Rotational power transmission device
Inventor: NONAKA HIROKI
IPC: B23Q5/04
Filed: 1999-01-18
Abstract: PROBLEM TO BE SOLVED: To restrain vibration at high speed rotation by providing a first torque transmission route through rollers and a second torque transmission route by gears in parallel with each other between an input shaft and an output shaft. SOLUTION: In traction drive through rollers 14, 15, 20, 21, torque is transmitted by the shearing effect of high viscous oil. The larger the relative slip between a drive side and a output side grows, the larger transmission torque becomes but the torque becomes constant at over prescribed slipping rate. Meanwhile, in gear drive through gears 5, 16, 17, 23, 22, 12, the larger the transmission torque grows, the larger the deformation of meshing gears becomes. Consequently vibration due to load variation is generated in the second torque transmission route of the gear drive mechanism. On the contray, in the first torque transmission route of the traction drive mechanism, torque is transmitted through of film, and hence it functions as a damper against elastic vibration.
