Patent JP-H01175407-A (JP)
Title: Semiconductor integrated circuit
Inventor: TETSUKA AKITOSHI
IPC: H03K5/133
Filed: 1987-12-29
Abstract: PURPOSE:To expand the range of a delay time and to improve the manufacture yield by controlling the gate voltage of a 1st constant current source field effect transistor(FET) from the outside of the delay circuit independently of the gate voltage of a 2nd constant current source FET. CONSTITUTION:The gate voltage VC of the constant source FETs T4 and T6 a source follower and the gate voltage VB of the constant current source FET T1 of a differential switch are independent of each other. This gate voltage VB is so set that logical amplitudes generated at R1 and R2 are 0.5-1.0V. The gate voltage of the constant current source FETs, T4 and T6, of the source follower is so controlled from outside as to be given a desired propagation delay time. Hence, the permissible range of variation of the current flowing through the source follower is much larger than that of the current flowing through the differential switch.

Title: Gps receiver
Inventor: PIITAA JIYON MINETSUTO
IPC: G01S1/00
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To make more expensive but less stable parts usable for an internal frequency transmitting source by receiving a sent reference frequency and correcting the error of the frequency transmitting source by using the reference frequency. SOLUTION: Data transmitted form each satellite contain accurate orbital data so that a section F can calculate the positions of the satellites. A navigation analyzing section C calculates the location of a user by using timing information from a tracking section B and positional information from the section F and outputs the location and the calculated error of a crystal oscillator 1 is stored in a section H. Since four or more satellites are tracked, the time of the user can be calculated from satellite signals. Reference information received by means of a receiver G is used so as to facilitate the capture of a timing signal from a first satellite which is caught at the starting time. Even when an inexpensive crystal oscillator, a frequency comparator 6 corrects the drift of the oscillator by using frequency information.

Title: Signal processor
Inventor: MATSUMOTO MASAAKI
IPC: H04N5/262
Filed: 1990-11-30
Abstract: PURPOSE:To obtain an output signal at a prescribed level based on the current of a side path by providing a circuit to form a current side path to a current switch circuit and cutting off the output signal corresponding to an input signal in the case of forming the side path. CONSTITUTION:When a switch S1 is turned on and a switch S2 is turned off, the current side path is formed from a power source to a constant current circuit CS 2 and a current I2 flows. Since the switch S2 is turned off, no current IQ2, flows to a resistor R2 and there is no voltage drop. Since a voltage generated by the current I2 and a resistor R1 is loaded to a transistor Q2, however, the voltage level of the output signal is lowered only for the voltage drop and reduced by half in comparison with the normal operation. Since the current I2 is stabilized, the level can be easily matched in the case of exchanging signals, multi-purpose use is enabled and an adjusting means can be unnecessitated.
