Title: Radio communication system
Inventor: WATANABE FUMIO
IPC: H04W16/24
Filed: 1986-08-13
Abstract: PURPOSE:To subdivide a zone without increasing the number of antennas of a base station, by executing the communication by radiating simultaneously and densely plural beams into a horizontal plane by an antenna of a master radio station. CONSTITUTION:The inside of a horizontal plane is divided into N pieces of zones alpha, and also, the inside of one zone alpha is divided into M pieces of smaller sub-zones beta. In this state, an antenna of a multi-beam, which can radiate M pieces of beams 4 is used for an antenna of a base station. In order to realize this communication system, it is necessary that the zone alpha in the horizontal plane is covered densely and fully with plural beams 4. Therefore, the radiation beams 4 of adjacent feeding horns are superposed to each other in the horizontal plane. In this way, the number of antennas of the base station can be made smaller than the number of radio zones.

Abstract: PROBLEM TO BE SOLVED: To allow the side wall of a case to have desired strength by forming a case by filling resin almost from the center of the side edge of the upper surface of its ceiling plate, using the resin composed of a fiber-reinforced resin, and by making the fiber direction after the filling top-to-bottom along the side wall. SOLUTION: The case 3 is formed in the shape of a box whose bottom is open by means of injection molding by using polyethylene terephthalate containing glass fiber as a resin material. Almost at the center of the side edge of its ceiling plate 18, a recessed part 20 that is recessed from the upper surface by a predetermined dimension is so formed as to be used for filling the resin in the injection molding of the case 3 and for preventing a protrusion such as a burr that may develop after the injection molding from protruding from the upper surface of the ceiling plate 18. The resin flows from the ceiling plate 18 toward a side wall 21 in the injection molding. Thus, the flow direction of the resin is top-to-bottom and that of the glass fiber is the same so that the vertical strength can be enhanced.

Title: Vehicle height control method
Inventor: HIBINO MASAMI
IPC: B60G17/015
Filed: 1984-09-09
Abstract: PURPOSE:To improve vehicle height control speed and accuracy in a vehicle height control method of a pneumatic control type, by detecting a difference between a time average vehicle height and a target vehicle height, and shortening a control time according to whether the difference is positive or negative. CONSTITUTION:When a vehicle height is detected by a sensor 1 and applied to a controller 2A, an operating unit 11 computes a time average vehicle height Ha every vehicle height operating time, and calculates a difference DELTAs between the time average vehicle height Ha and a target vehicle height St. Then, the operating unit 11 determines a control time DELTAt corresponding to the difference DELTAs in a control map, and detects whether the difference DELTAs is positive or negative. If DELTAs is positive, a suction valve 3 and an exhaust valve 4 are opened to reduce an air pressure in a suspension to thereby lower the vehicle height. If DELTAs is negative, the suction valve 3 and a compressor 7 are operated to increase the vehicle height. At this time, the control map is divided into a lowering and a lifting control map, and a lifting control time is increased. Thus, vehicle height control accuracy and speed may be improved.

Title: Motor torque controller of electric vehicle
Inventor: OZAKI MASAHITO
IPC: B60L15/20
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To provide a motor torque controller of an electric vehicle which realizes smooth and natural acceleration corresponding to accelerator operation, when the vehicle pulls away and on other occasions. SOLUTION: A creep torque is set based on a vehicle speed detected by a vehicle speed detecting means 13, and an accelerator torque is set based on the amount of accelerator operation detected by an accelerator operated amount setting means 12. The detected creep torque and accelerator torque are added together to calculate a powering torque command value. As a result, it is possible to increase accelerator torque, immediately after accelerator operation is started to pull away, so that the vehicle can swiftly drive off. Furthermore, after pulling away, creep torque is reflected in powering torque command value to prevent its abrupt drop.
