Title: Signal converter
Inventor: ERITSUKU FUAA ESERITSUJI
IPC: H03K19/0175
Filed: 1989-12-19
Abstract: PURPOSE: To simplify constitution and to set a signal converter to be integrated in a single chip with a CMOS circuit by generating a reference signal from an ECL clock signal and a signal obtained by level-shifting an inverted ECL signal and comparing the reference signal with the level-shifted data signal. CONSTITUTION: The two clock signals which are level-shifted by level shift circuits 16 and 18 are compared by a CMOS comparator 22. Thus, the clock signal fitted to CMOS is generated. The clock signal where the phase is alternated becomes the reference voltage of the comparator 22. ECL data which is shifted by a level shift circuit 12 by four volts in a positive direction is compared with reference voltage outputted from a voltage divider by means of the CMOS comparator 20. The output of the CMOS comparator 20 becomes a data output signal fitted to CMOS logic. The signal converter can be integrated in a single chip by using a standard CMOS process and it can be driven by a single 5 volt power source.

Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To monitor the state of a driver from a driver's picture obtained by a camera. SOLUTION: A driver is successively photographed by a camera 10, and supplied to a facial direction detecting device 12. The facial direction detecting device 12 calculates a difference between the inputted driver's pictures, and segments a part whose difference value is a constant value or more as a facial position. The facial direction of the driver is detected based on the segmented facial picture and outputted to a looking-aside calculating part 14. The looking- aside calculating part 14 judges the presence or absence of the looking-aside of the driver from the facial direction and a steering angle or speed. Also, when the finite difference value can not be obtained, the time interval of the picture is increased, and the difference value is calculated gain.  When the difference value can not be obtained even after the time interval of the picture is increased by more than a constant time, the looking-aside calculating part 14 judges that the consciousness of the driver is lowered.

Abstract: PURPOSE:To prevent excessive rise in the temperature generated in a feedback operation using a temperature sensor alone by determining a temperature rise from a difference between the humidity at a green house and a set humidity to repeat a raising of temperature within a specified range with the ON or OFF operation of a burner. CONSTITUTION:When a humidity sensor 12 detects room humidity reaching set humidity 15 set on a humidity controller 11A, the room temperature at the moment is detected with a humidity sensor 13.

Title: Power-on resetting device
Inventor: IKEDA ISATO
IPC: G06F1/24
Filed: 1990-11-27
Abstract: PURPOSE:To obtain a reset signal which has a delay time required to reset an internal circuit by outputting a signal which is later between the outputs of two reset circuits whose power-on reset signal differs in rising characteristic. CONSTITUTION:When Vcc rises steeply, POP1 follows up it with a sufficient time, but POR2 reacts immediately and also follows up it. At this time, a signal POP is generated by ANDing the POR1 and POR2 and follows up the Vcc with a sufficient time. When the Vcc rises slowly, on the other hand, the POR1 reacts to the rise of the Vcc relatively early, but the POR2 follows up it with a sufficient time. Thus, the signal POR which has an enough time to reset the internal circuits regardless of the rising state of the Vcc can be generated.
