Title: I2l circuit
Inventor: KATSUMI CHIAKI
IPC: H03K19/091
Filed: 1985-07-02
Abstract: PURPOSE:To suppress the entire current consumption by increasing the injection current of the 1st I<2>L gate more than the 2nd I<2>L gate injection current so as to improve the duty ratio of an input signal. CONSTITUTION:The injection current IINJ1 of the 1st I<2>L gate 2 is set to a value larger than the injection current IINJ0 of the 2nd I<2>L gate 3. When an input signal IN changes from an 'H' to an 'H' level, the collector potential A of an NPN transistor (TR) 5 of an input circuit 1 is charged by the injection current IINJ1 of the 1st I<2>L gate 2. The delay time in this case is 1/3 in comparison with a conventional constitution. Since the required operating frequency is lowered, it is possible to decrease the injection current of the 2nd I<2>L gate 3 and the entire current consumption is reduced.

Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To realize a laser, wherein the response speed is fully at high speed, when the laser light is directly controlled and control resolution is high by using high-speed optical feedback control function. SOLUTION: Switching circuits 2A, 2B are used in a power source, and an injection current into a stimulation light source 7 is subjected to instantaneous value control. In the instantaneous value control, the quantity of a light outputted from laser medium 8 is monitored with a light quantity detecting means 12, the detected value of the quantity of light is compared with an optical output setting value applied from the outside 90 by using an optical output control means 13, and a laser light output is instantaneously made to converge to a prescribed value, while the output indicating value of the injection current to the pumping light source is corrected, so as to reduce the error amount during the period of the optical output.  In this way, even if the optical output set value is constant, the error amount between the detected value of quantity of light and the optical output set value will change, when the laser light output is changed. High-speed optical feedback control which instantaneously corrects the output indicating value of the injection current into the pumping light source in response to change of the error amount, is performed continuously.

Abstract: PURPOSE:To enable a narrower base width to be achieved by doping impurities whose diffusion coefficient is larger than that at other parts onto a part which is directly below a genuine base of a buried layer when forming a buried layer and by utilizing the plenomenon that the impurities with a larger diffusion coefficient are raised by later heat treatment. CONSTITUTION:When doping impurities of an N<+> buried layer 2a for a P sub strate 1, impurities with a larger diffusion coefficient than that at other parts are doped at a part which is directly below a genuine base and an epitaxial layer 4 is allowed to grow on it, thus forming a separation diffusion layer 3 for element separation. The impurities with a larger diffusion coefficient which are doped directly below the genuine base of the N<+> buried layer 2a is raised as shown in figure by later heat treatment, thus suppressing diffusion of boron ion at the genuine base part of a base diffusion layer 5 due to implanta tion of boron ion, enabling impurity distribution to be sharp, and helping to achieve a narrow base width.
