Abstract: PURPOSE: To position a vehicle with a considerably simple system. CONSTITUTION: The receiver 16 of the vehicle 15 receives signals from multiple NAVSTAR wide positioning system GPS satellites 11, 12, 13 and 14. A part of the signals are accumulated in a memory 18 before they are transmitted again by a transmitter 19. A base station 35 directly receives the signals from the NAVSTAR GPS satellites 11, 12, 13 and 14 using a second receiver 38 and receives transmission from a moving unit using a first receiver 36. A control/calculation means 37 in the base station 35 decides satellite calendar coarse information, measures the transmission time of the signal between the satellites and the vehicle or radio wave delay and the control/calculation means 37 calculates the position of a vehicle unit with the information.

Title: Power-on resetting circuit
Inventor: SUZUKI TOSHITATSU
IPC: H03K3/0231
Filed: 1983-02-26
Abstract: PURPOSE:To perform the stable power-on resetting of a low-voltage operating circuit even in a stationary oscillation state by switching a reference voltage by a resetting release output in power-on operation and setting the reference voltage higher before releasing than in stationary operation. CONSTITUTION:When the application of a source voltage starts, a TRQ3 is off and the reference comparison voltage of a comparator C3 for power-on resetting is 2VBE. When the source voltage rises to charge a capacitor Cosc until its terminal voltage is higher than 2VBE, the output of the comparator C3 is inverted to enter a reset-off state, and the TRQ3 turns on to form a short-circuit across a diode D3; and the reference comparison voltage attains VBE depending upon only a diode D2 and the terminal voltage across the capacitor Cosc drops almost to 1.0V, performing oscillating operation. Therefore, even when this circuit is applied to the low-voltage operating circuit, secure operation is carried out, resetting is released after the source voltage rises sufficiently, and the stationary oscillation operation never becomes unstable.

Filed: 1994-03-02
Abstract: PURPOSE:To eject a paper sheet without taking inside the reverse part feeding part, to omit a miss copy and to reduce an operational load on a user by providing a processing means for forming the image on both sides or one side of the image formation medium and an ejecting means for ejecting the image formation medium after forming the image. CONSTITUTION:The second document is taken in an automatic document feeder 39 and set on the reference position of a document platen 38. Consequently, with respect to the other side of the copying paper sheet taken out from a reverse paper feeding part 49, the copying corresponding to the second document is made by the image forming part and the sheet is ejected to a paper ejecting tray 55. In the process of taking in the first original, when the detection signal from a document detecting means 67 is not supplied, the automatic both side mode is prohibited and converted to the single side mode by the CPU basing on the judgment that the document is single. Thus, the copying paper sheet corresponding to the document is not transported to a reverse paper feeding paper 49, but ejected to the paper ejecting tray 55. In other words, at the time of the single document, the single side mode is selected and the paper sheet is ejected instead of being taken in the inside.
