Title: Air-fuel ratio control device
Inventor: KOMAI YUKIRO
IPC: F23N5/18
Filed: 1987-05-22
Abstract: PURPOSE:To keep a stable combustion by a method wherein a signal from a sensor for detecting the number of rotation of a combustion fan is fed back in such a way that the number of rotations shows a specified value and a signal from a current sensor is fed back in such a way that a current value of a motor becomes constant. CONSTITUTION:A combustion adjusting valve 6 is controlled by a controller 10 so as to eliminate a difference between a hot water temperature detected by a hot water temperature sensor 11 and a temperature set by a hot water temperature setting unit 12, an amount of fuel is set and injected from a nozzle 5 and then ignited with a burner 1. The controller 10 feeds back a signal from a current sensor 7 to a driving circuit 9 in such a way that the amount of air is reached in proportion to a desired amount of fuel and further in such a way that a current value detected by a current sensor 7 exceeds a predetermined current value, and then feeds back a signal from a sensor 8 for detecting the number of rotation exceeding the desired number of rotation. An arrangement of air-fuel ratio controlling device enables a countermeasure to be attained against a lack of number of rotation when the combustion fan 3 is started to operate, a disturbance of the combustion fan 3, an inner disturbance such as a fixing of a shaft an increasing of loss of pressure in the combustion device or an outer disturbance of assembly or the like and then stable combustion can be maintained.

Title: Field effect transistor amplifying circuit
Inventor: UCHIUMI YOSHIO
IPC: H03F3/16
Filed: 1980-09-12
Abstract: PURPOSE: To obtain an output signal whose linearly is satisfactory, by constituting so that an input signal and a reverse signal are applied to two FETs having the same characteristics, respectively, and supplying a difference of each drain of each FET to a load.  
     CONSTITUTION: When an input signal V i  is supplied to an input terminal T 1 , a current i 1  flows to the drain of an FET6. Since an FET3 and an FET4 have the same characteristics, a reverse signal of -V i  is generated between the source and the gate of the FET4, and is supplied to an FET8. Since the FET6 and the FET8 have the same characteristics, when a difference current between a current i 2  flowing out from the source of the FET8, and the current i 1  flowing to the FET6 is denoted as i 3 , a current flowing to a load 11 becomes a value which has subtracted the difference current i 3  from a current I flowing out from a constant-current source 10. When voltage V 0  across the load resistance 11 is outputted as an output signal, the output signal whose linearity is satisfactory to the input signal is obtained.

Title: Deposition of film
Inventor: HANAZONO MASANOBU
IPC: H01L21/31
Filed: 1981-08-14
Abstract: PURPOSE:To form a highly accurate film with the desired shape of exposed surface without giving any damage on the substrate by providing thick double layers on the substrate surface and forming it to the prescribed thickness by irradiating the accelerated ion to such layer. CONSTITUTION:The first film 3 is formed on the region where the concave and convex portions of substrate 1 are deposited. Since the first film 3 is formed  almost in the equal thickness, the exposed main surface 301 shows the concave  and convex surface along the concave and convex shape of the substrate surface. The second film 4 is formed on the main surface 301 of the first film 3.  The second film 4 is the positive photo resist film deposited by the rotating coating method. The positive type photo resist increases fluidity when it is heated up to a temperature of about 160-180 deg.C and flows by itself, making small the concave and convex shape. Then, the accelerated ion is irradiated to the exposed surface of the second film 4 and impact of such irradiation removes the convex portion of entire part of the second film 4 or a part of the first film 3. It is desirable to execute this process by the ion beam milling method.

Filed: 1989-05-20
Abstract: PURPOSE:To use the code for the transmission of a bit string and other processing by generating a binary code the same as its position code as to a bit position where a bit code is 1 and generating a code with binary number of each digit of the position code inverted as to a bit position where a bit code is 0. CONSTITUTION:The sequence corresponds to 8 bit locations of a column 1 of a primitive bit string in the order from the left to the right, and when bit codes are sequentially 1, 1,0, 1, 0, 0, 1, 0 sequentially up to 1st-8th bit locations, since the result shows M=1000, N-1=111, n=3, n+1=4 and P=1000, the results are 1000, 1001, 1010, 1011, 1100, 1101, 1110, 1111 sequentially up to the 1st-8th bit locations. Thus, when a bit displacement code 3 representing both each bit location and its bit code of the primitive bit string is formed, the relation of 1000, 1001, 1010, 1011, 1100, 1101, 1110, 1111 is obtained sequentially. Thus, the bit displacement code is used for the transmission or other information processing system processing.
