Title: Integration circuit and filter circuit using the integration circuit
Inventor: OGAWA ATSUSHI
IPC: H03H11/04
Filed: 1993-12-08
Abstract: PURPOSE:To make it possible to increase maximum amplitude even when power supply voltage is low and to change the integration constant of an integration circuit by connecting a 1st TR connected to an input terminal and a 2nd TR connected to an output terminal by prescribed connection. CONSTITUTION:When it is defined that the resistance values of resistor elements 105, 106 are respectively R11 and R12, the electrostatic capacity of a capacitor 107 is C11 and the current supply of a current source 108 is ICTRL, the integration constant of the integration circuit is obtained by R11.C11.exp{(ICTRL.R12)/Vt}. Provided that V1=k.T/q (k is Boltzmann's constant, T is absolute temperature, q is electric charge, and the Vt is about 26mV at room temperature). When the voltage effect at the time of the R12 (i.e., ICTRL.R12) is set up to 18mV, the integration constant can be changed. Even when production dispersion exists in the resistance voltage R11 of the resistor element 105 or the electrostatic capacity C11 of the capacitor 107, the integration constant can be fixed.

Filed: 1991-11-22
Abstract: PURPOSE:To obtain a liquid fuel burner which gasifies liquid fuels such as petroleum and burns the gasified liquid fuels. CONSTITUTION:A liquid fuel (a) and a combustion air (b) are supplied. A burner head 12 is installed to the upper part of an opening peripheral edge 2c of a vaporizer which uses an electric heater 8 to gasify the liquid fuel (a).
