Abstract: PURPOSE:To provide a GPS receiving apparatus which can simply and stably obtain a temporary present position based on which a correct present position is to be calculated. CONSTITUTION:The GPS receiving apparatus is provided with an antenna 1 for receiving satellite signals, a detecting means 2 for taking out a navigation message from the received signals, and a position measuring means 3 for measuring and operating the position through analyzing the navigation message. In the GPS receiving apparatus, an elevation angle detecting means 8 for detecting the angle of elevation of a satellite from the intensity of the receiving signals from the satellite is provided, and a measuring means 3 calculates a temporary measuring position on the basis of the angle of elevation of the satellite detected by the detecting means 8 and the present position of the satellite obtained from the navigation message. The detecting level of the satellite signal is weakened as the signal passes the atmosphere. When the angle of elevation is large, the detecting level is high. On the other hand, when the angle of elevation is small, the detecting level is low. The elevation angle detecting means 8 determines the angle of elevation of each satellite from this correlation, and the measuring means 3 calculates the rough measurement position from a plurality of angles of elevation of satellites and the position of each satellite. The measurement position is calculated based on the rough measurement position.

Title: Coke receiving running control method for coke oven fire extinguishing vehicle
Inventor: SHIMOMURA MOTOYOSHI
IPC: H02P25/098
Filed: 1993-02-18
Abstract: PURPOSE:To allow stabilized coke receiving running by employing a corrected standard coke receiving speed as a speed command signal. CONSTITUTION:Rotational speed (f) of a motor 1 is detected by a speed detector 3 through a generator 2. A first operating circuit 5 compares the rotational speed (f) of the motor 1 with a set value (r) of standard coke receiving speed and the difference DELTAr' is corrected by a correction operating circuit 8 through a dead band 7. A second operating circuit 9 adds the correction value DELTAr' to the set value (r) to produce a corrected set value (r') which is then compared by a third operating circuit 10 with the rotational speed (f) to determine a difference (e). The difference (e) is amplified by an error amplifier 6 in order to control a thyristor stack 11 thus controlling the rotation of the motor 1. This method allows stabilized coke receiving running.

Filed: 1995-03-13
Abstract: PURPOSE: To transmit much data without increasing the transmission speed by sending bus data by a bus data transmitting means right after an effective screen after a measurement taken for a specific time of a timer means ends. CONSTITUTION: When a vertical synchronizing signal is inputted to a vertical synchronizing signal detecting means 1, a vertical synchronizing signal detecting means 1 detects the front edge of the vertical synchronizing signal and informs the timer means 2 of that. The timer means 2 once receiving information from the vertical synchronizing signal detecting means 1 initializes its initial timer. Then its data is decreased at constant time intervals and when the data reaches 0, the bus data transmitting means 3 is informed of that. Then the bus data transmitting means 3 sends the bus data to various ICs (IC-1, IC-2, IC-3, etc.) 4. Consequently, much data can be transmitted without increasing the transmission speed.
