Title: Shift register
Inventor: NISHIMOTO TOSHIO
IPC: G11C7/10
Filed: 1986-02-18
Abstract: PURPOSE:To quickly drive a large capacity load by low power consumption by constituting such that each output of a dynamic type comparator is given to a buffer and its output is linked to a latch circuit. CONSTITUTION:The 1st clock phi1 fetches an input to the dynamic type comparator C, while the 2nd clock phi2 secures its output. However, since the comparator is of a dynamic type, a conducting current is not conducted. Afterward, the 3rd clock phi3 drives the buffer B to amplify the output of the comparator C. Thus the comparator and amplification are made individually, whereby the large capacity load can be quickly driven, and a quick action can be obtained in spite of low power consumption. As the output is provided with a latch circuit, the output is connected to a power source voltage or a grounding potential in a low impedance state even if the clock phi3 comes to a low level, and therefore the output holding time has no limit.

Title: Flame detector
Inventor: TAKECHI HIROSHI
IPC: F23N5/12
Filed: 1987-02-18
Abstract: PURPOSE:To make it possible to detect a flame at a low voltage by detecting the difference between the positive and negative values of a current across the burner and terminal. CONSTITUTION:When there is a flame at a burner 24, an electric current flows from a terminal 25 to the burner 24 if VA=VCC to cause to voltage to drop at a resistor 23, and so, the VC becomes a voltage lower than VCC by VFR. If VA is at the GND level, a current does not flow from the burner 24 to the terminal 25 due to a rectifying action of the flame, and so, the VC becomes the GND level; whereas VD is (VCC-VFR), VE is at the GND level and VF is 2VK. By setting VK between VCC/2 and (VCC-VFR), the output VO from an operation amplifier 34 becomes HIGH if there is a flame at the burner 24, and LOW if there is no flame. In this instance, the difference between the positive and negative values of current across the burner 24 and terminal 25 is detected, thus enabling the flame to be detected even at a low voltage.
