Title: Sheet sorting device
Inventor: KISHINO MINORU
IPC: B65H31/14
Filed: 1986-02-18
Abstract: PURPOSE:To prevent disorder in a stack of sheets caused by catch-up of sheets to be discharged in a wedge-shape gap, by providing sheet side edge correcting and holding surfaces on both side edge of a narrow section in the bottom surfaces of a tray, which are inclined to both right and left of the bottom surface of a tray. CONSTITUTION:When sheets to be discharged are distributed and stacked in a tray 4, the superposed center section of a stack of sheets becomes higher and higher so that the angle between the topmost sheet and each sheet side edge guide member 48 is gradually decreased so that the side edges of the sheet are caught up in the wedge-shape gap 57 between the guide member 48 and the stacked sheets, and therefore, the sheet comes to a stop before it reaches the side edge 52 of a wall section 50, so that the front ends of stacked sheets are not uniformly lined up. Accordingly, side edge correcting surfaces 46, 47 which extend in a substantially horizontal direction, are provided in the right and left corner parts of the bottom surfaces 44, 45 which are inclined to the left and right of the tray 4, and therefore, curls in each side edge which grow as the sheets are stacked are corrected to prevent the formation of the wedge shape gap 57. Thus, it is possible to prevent disorder in a stack of sheets, thereby it is possible to stack and store sheets in order in the tray.

Abstract: PURPOSE:To shape a thermal insulating structure which can follow the shape of a heat-insulated body and can be filled into a gap part by filling synthetic resin foamed particles in a flexible plastic container with a specified oxygen permeability and reducing the gas pressure in the gap part formed in the container to a specified pressure. CONSTITUTION:Synthetic resin foamed particles are filled in a flexible plastic container with an oxygen permeability of at most 100cm<3>/sec cm<2>.cmHg and the gas pressure in the gap part formed in the container is reduced to 1-759Torr. Mutual positional displacement of foamed particles is suppresssed thereby and the whole shape of the filling material is held against the outer pressure. It is possible therefore to obtain shapability following the shape of a heat insulating body in the application, and to obtain self-standing properties as a heat insulating structure.

Filed: 1991-01-31
Abstract: PURPOSE:To improve high frequency characteristics of an N-P-N transistor without increasing steps in a bipolar integrated circuit in which vertical P-N-P transistor is placed in mixture. CONSTITUTION:When an N-type base region 110 of a vertical P-N-P transistor is formed by ion implanting N-type impurities, the ions are implanted directly under a region to be formed with an emitter of an N-P-N transistor thereby to form a relatively high concentration N-type collector region 110'.

Title: Movable beam antenna
Inventor: HONMA YOSHIHIRO
IPC: H01Q3/14
Filed: 1979-03-20
Abstract: PURPOSE:To reduce the size of the movable part where the correction is given to the shift of the beam radial direction and thus reduce the driving energy for the stationary satellite, by providing the movable dielectric lens into the wave propagation path from the primary radiator to the reflector. CONSTITUTION:Dielectric lens L is provided into the wave propagation path between primary radiator H and reflector M1, and thus the travelling directions coincide with each other between wave surfaces W1 and W2. And the wave radiated from horn H enters reflector M1 after passing through lens L. On the other hand, in case the position of the stationary satellite varies from the optimum position, this movement is detected. And then lens L is shifted in order to secure the optimum radial direction of the beam. And the size of lens L can be reduced by providing lens L near the opening of horn H, thus reducing the driving energy.

Title: Variable attenuating circuit
Inventor: ISE TAICHIROU
IPC: H03G3/10
Filed: 1981-03-07
Abstract: PURPOSE:To improve frequency characteristics by interlocking and varying a variable attenuating circuit composed of a pin-diode and a frequency compensating circuit composed of a varactor diode. CONSTITUTION:As the positive potential of a direct current applied to an input terminal 3 nears the ground potential, a current flowing through a pin-diode X1 decreases and the pin-diode X1 has higher resistance. Then, the loss at a high frequency due to a load capacitance C0 increases. In this case, a potential, however, applied to a varactor diode X2 drops, so the capacity increases. As a result, a signal sent to an output terminal 2 through the varactor diode X2 and a capacitor C3 increases to compensate the loss at a high frequency.

Title: Constant velocity universal joint
Inventor: YOSHIDA KAZUHIKO
IPC: F16D3/2237
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To improve strength, durability and life time without increasing dimension of a universal joint, and to provide the stable torque transmitting function, independently of working angle by setting the offset angle of a ball track within a specified range. SOLUTION: An offset angle ϕT formed by the center OTO of the spherical surface of a guide groove 2b of an outside member 2, a cross point Q of a joint flat surface P and PCD, and a center OTI of the spherical surface of a guide groove 3b of an inside member is set at about 5.5-7.5 degrees. This angle is smaller than that of the conventional one, and depth of the guide grooves 2b, 3b become nearly even in the axial direction in comparison with the conventional one (expressed with a broken line). With this structure, since the depth of a groove is large at shallow parts of the guide grooves 2b, 3b and a contact ellipse is hard to ride over a guide groove shoulder part even under high load conditions, generation of notches in the shoulder part can be prevented, and the strength and durability of the guide grooves 2b, 3b can be improved.  Strength and life time of a holder 5 can be improved by forming the holder 5 thick. Furthermore, satisfactory workability is obtained by the offset angle ϕT.
