Title: Phase shifter
Inventor: KITANO SHINICHIRO
IPC: H01P1/185
Filed: 1992-02-12
Abstract: PURPOSE:To reduce number of PIN diodes in use used to select any of transmission lines. CONSTITUTION:A PIN diode 1 is connected between end points (between points A and B) of transmission lines 4, 6 of a 1/4 wavelength, and a transmission line 5 of a prescribed length is connected between other end points (between points C and D) of the transmission lines 4, 6 of a 1/4 wavelength. Moreover, a PIN diode 2(3) is respectively connected between the point C(D) and ground. Moreover, a forward bias voltage is applied to the PIN diodes 1, 2, 3 via high frequency block circuits 7, 8 to turn on the diodes, then since the impedance is an open state when viewing the transmission lines 4, 6 of a 1/4 wavelength from the points A, B, an RF signal is outputted through the PN diode 1. When a reverse bias voltage is applied to the PIN diodes 1, 2, 3 and they are turned off conversely, the RF output is outputted through the transmission lines 4, 5, 6. A desired phase quantity is obtained by adjusting the length of the transmission line 5.

Title: Paper dust remover
Inventor: ITAYA KEIJI
IPC: B65H3/46
Filed: 1980-02-29
Abstract: PURPOSE:To ensure an electrostatic removal of the paper dust attached to the paper before the paper reaches a picture forming device, by securing a touch between the paper and a paper dust adsorbing roller having the electrifying charge on its surface. CONSTITUTION:The copying paper 11 is carried to the photosensitive drum 16 via the carrying roller 13. In this case, the paper 11 has a touch to the paper dust adsorbing roller 21 that is turned in the direction of the arrow (u). At the same time, the electrifying charge is provided on the surface of the roller 21 by the corona charger 22. Thus the paper 11 produces the inductive polarization due to the charge on the surface of the roller 21 when the paper 11 touches the roller 21 under carrying. Thus the paper 11 is adsorbed electrostatically to the roller 21. As a result, the paper dust can be removed from the surface of the paper 11.

IPC: H02K19/14
Filed: 1988-02-08
Abstract: PURPOSE:To contrive to improve characteristics of an apparatus and to increase the pull-out torque thereof by inserting and fixing a non-magnetic material plate in a rotor core perpendicularly to the quadrature axis of said apparatus to increase the magnetic reluctance of said quadrature axis and by making the gap length to the direction of said axis larger than that to the direction of the direct axis of said apparatus. CONSTITUTION:A stator 1 has a round shape, while a rotor 2 has an elliptic shape of nearly 90% (round). Said ellipse not only makes the gap length of its quadrature axis larger than that of the direct axis but also smoothly changes said gap length in the circumferential direction to control harmonic components in a gap flux density distribution. Also, said ellipse is perpendicular to the direction of the quadrature axis (minor axis) of the rotor 2 and centers on the rotor shaft center, and non-magnetic material plates 3 are inserted and fixed on both sides of said shaft center. Said plates 3 increase the magnetic reluctance of said quadrature axis and are made of material such as copper plates and aluminum plates difficult for a magnetic flux to pass through. In this manner, the gap flux density distribution changes smoothly and the magnetic reluctance varies largely in the quadrature axis.

Title: Oil feed apparatus with residual oil discharge means
Inventor: YASUDA HAJIME
IPC: B67D7/42
Filed: 1989-02-06
Abstract: PURPOSE:To prevent spillage of oil from a feed opening, so that there will be no contamination of a vehicle and occurrence of fire hazard by releasing pressure air into a discharge pipe of a nozzle when the oil feed is limited to expel the oil rapidly therefrom, even if it is full. CONSTITUTION:An air feed valve control circuit 75, when the input of a flow amount pulse signal (a) has stopped beyond a predetermined time, judges that oil feed is terminated and generates a valve opening signal (oil feed limiting signal) w for time Tn preset in an air feed time setting circuit 74 to open an air feed valve 70. When the tank becomes full or oil reaches the preset value to stop oil feed operation, the generation of the flow amount pulse signal (a) is stopped and, therefore, the air feed valve control circuit 75 generates the valve opening signal w for time Tn to open the air feed valve 70. Even within time Tn, however, the output of this signal w is stopped upon the generation of a new flow amount pulse signal (a) and, since there is again stoppage of the generation of the signal (a), the valve opening signal w is generated for time Tn. Upon opening of the air feed valve 70, since pressure air is released into an oil flow passage 20, the oil in a discharge pipe is carried out rapidly.
