Title: Controlling system of mobile communication system
Inventor: MURASE ATSUSHI
IPC: H04B7/26
Filed: 1983-03-04
Abstract: PURPOSE:To decide exactly a level, and to shorten a connection control time by assigning a different time slot to each base station and sending a control signal. CONSTITUTION:In case when communication between a mobile station and a base station 3 is set in plural radio zones 2 by using a common control channel, each base station determined the position of each transmitting time slot so that it is not overlapped with each station, basing on a synchronizing signal 6. When a signal is transmitted by a timing which is not overlapped with every base station, the mobile station measures a demodulating level at every time slot by which each intrinsic control signal is transmitted with regard to each base station 3, basing on a signal 6. Subsequently, a time slot by which the maximum demodulating level appears is decided. As a result, the base station to which a communication should be executed exactly is decided, and also its decision is executed in advance, therefore, the connection control time is shortened.

Title: Optical fiber simulator
Inventor: MORI MASAKAZU
IPC: H04B10/00
Filed: 1980-03-19
Abstract: PURPOSE:To generate a simulated optical signal which has the similar arbitrary band characteristics of an optical fiber in a simple structure, by employing a Thomsen filter with quartic or more dimensions whose attenuating characteristics are the same as the optical fiber. CONSTITUTION:A cutoff frequency f3dB is based on an equation II for the Thomson filter 2 with quartic or more dimensions whose attenuating characteristic is square Gauss characteristic. A frequency band fCL is based on an equation I for the optical fiber whose attenuation characteristics is the square Gauss characteristic. If the cutoff frequency f3dB is selected so as to obtain fCL/(2<1/2>)with respect to the frequency band fCL, an electrical signal from an analog or digital signal generator 1 is applied to an LED4 via the filter 2 and a light emitting element driving circuit 3. The amount of light emission of the LED4 linearly varies with the amplitude of the applied electric signal. Therefore, the arbitrary band characteristics of the optical fiber can be simulated in a simple structure, the optical signal is outputted, and the accurate test of the optical transmission system can be performed. In this case alpha and alpha' are the optical-signal and the electrical-signal attenuating quantities, respectively, and f is the frequency in the band.

Title: Outer tube of vibration isolating joint
Inventor: FURUYA KATSUMI
IPC: F16F15/126
Filed: 1989-02-16
Abstract: PURPOSE:To reduce shearing force acting on a vibration isolating member so as to largely enhance the durability of the outer tube in the title by forming the load receiving face of a protrusion on the inner face of the outer tube and causing the load receiving face to substantially agree with a face including both the center line of the outer tube and a line in the radial direction. CONSTITUTION:Each side face of a protrusion 7 serves as a load receiving face 8, which is formed in such a manner that it substantially agrees with a face including the center line of a joint outer tube and a line in the radial direction; i.e. the angle theta defined by the line OA linking the center point O with a point A on the load receiving face 8 and by a tangent (a) at the point A is set ideally 0 degree or less than 20 degrees at most. By setting the angle of the load receiving face 8 in this way, a force F perpendicular to the OA when transmission torque acts on the load face, and a component force Fr perpendicular to the tangent A almost agree with each other and the component force Ft in the tangent direction becomes very small. A large part of force acting on a vibration isolating material 3 therefore consists of compressive force and shearing force scarcely acts thereon.

Abstract: PURPOSE:To properly suppress the rolling of a car body by setting the steering angle at which the ground clearance adjustment is necessary on the basis of the car speed and feeding and discharging an aimed quantity of supplied and discharged oil which is estimated at each set steering angle and eliminating the useless operation in feeding and discharging oil. CONSTITUTION:In a controller 11 which receives each detection signal supplied from a number of ground clearance sensors 10a-10d, steering angle sensor 12, and a car speed sensor 13, a means 14 sets the unit steering angle at which the ground clearance adjustment at a prescribed car speed is necessary. Further, a means 15 estimates the lateral acceleration speed generated on a car body at each steering angle. Further, a means 16 calculates the change of the roll angle generated by the lateral acceleration speed and the change of the length of a hydraulic cylinder installed on each wheel. A means 17 sets an aimed oil feed/discharge quantity supplied or discharged from the hydraulic cylinder according to the variation of the length of the hydraulic cylinder. Then, each time when the aimed steering angle and the detected steering angle accord, a CPU 18 controls each oil feed/discharge means 7a-7d on the basis of the aimed oil feed/discharge quantity.

Filed: 1981-03-16
Abstract: PURPOSE:To improve resolution in the vertical direction by twice, by shifting the display positions of plural lines through a vertical deflection means by a half of a line interval in every vertical period. CONSTITUTION:In order to perform vertical deflection, a signal is divided into 16 stages, for example, and a vertical deflection signal (v) with ascending level and a vertical deflection level (v') with descending level are formed and applied to conductive plates 13, 13' of a vertical deflection electrode 4, respectively. Thus, an electron beam is deflected into 16 stages in every division in the vertical direction and rasters of 16 lines can be drawn only by one electron beam. Moreover, stairlike outputs are switched in every vertical synchronization so that the display position of the raster in each line is shifted about an half of the line interval in the vertical direction. At vertical deflection, display positions alphan-pin and alphan+1-pin+1 of each line are shifted each other by about a  half of the line interval. Consequently, pictures are displayed in the condition  that line density on a screen increases twice.
