Title: Method for controlling air-fuel ratio of internal combustion engine
Inventor: KIMURA HIROSHI
IPC: F02D41/14
Filed: 1990-04-20
Abstract: PURPOSE:To prevent deterioration of emission by changing the rich/lean judgment voltage of an O2 sensor to rich side between air-fuel ratio feedback area and power increasing area, and conducting feedback control of air-fuel ratio on the basis of this voltage. CONSTITUTION:An electronic control device 5 regulates fuel feed quantity on the basis of the starting power of an O2 sensor for detecting oxygen concentration in exhaust gas, sets an air-fuel ratio feedback area for regulating the air- fuel ratio of the mixture supplied to a combustion chamber 4 to about a theoretical air-fuel ratio and a power increasing area for regulating the air-fuel ratio of the mixture rich at a determined high load and high speed time. In this air-fuel ratio control method, the rich/lean judgment voltage of the O2 sensor 12 is changed to rich side between the air-fuel ratio feedback area and the power increasing area, and the feedback control of air-fuel ratio is conducted on the basis of this judgment voltage. Hence, when the control area of air-fuel ratio is changed, drivability can be effectively prevented from rapidly changing, and emission can be improved.

Abstract: PURPOSE: To prevent a processing speed from decreasing by disconnecting a microprogram memory, sequence program memory and scratch pad memory from a common bus and then by making access from other equipments possible.  
     CONSTITUTION: By a multiplexer, input buffer 5 selects state 9 of one process selected by address 112 of input-output controller 12 and holds value 108 at that moment by latch command 103 of input-output controller 12 so as to hold and output it to an input-output processor as signal 111. This signal is written in a fixed bit of input-output memory 20 by input-output processor 12 by way of change- over gate 23. In output buffer 6, a corresponding flip-flop is latched to the value of output data line 111a at that time by latch signal 103a and alternative signal 109 obtained by decoding address 112 of input-output processor 12, thereby driving relay 10.

Title: Make-connection fare adjusting machine
Inventor: TAGAMI HIDEAKI
IPC: G07B15/00
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To receive an accurate fare adjustment amount by detecting the boarding direction based on the boarding station recorded on an original fare adjustment ticket and the station where a fare adjusting machine is installed and calculating a prescribed make-connection fare adjustment amount. SOLUTION: A user of a commutation ticket available in the section between stations A and B of an (a) railroad company line puts his ticket into a make-connection fare adjusting machine installed at a station C to get off at a station D. Under such conditions, the data on the boarding station are read and the so far boarding direction is detected based on the boarding station and the station C where the fare adjusting machine is installed. On a boarding route 1, a normal make-connection state is defined in its own railroad company and accordingly the boarding fare covering the station B of the (a) railroad company through the station D is calculated as a make-connection fare adjustment amount.  On a boarding route 2, the free boarding is decided between stations C and D of a (b) railroad company and accordingly the boarding fare covering the station C through the station D is calculated as the make-connection fare adjustment amount. When this calculated fare adjustment amount is put into the fare adjusting machine, a make-connection fare adjustment ticket available up to the station D is issued.

Title: Manufacture of stainless steel
Inventor: TAKI CHIHIRO
IPC: C21C7/076
Filed: 1993-05-07
Abstract: PURPOSE:To resolve the problem of Cr-loss or resulfrization in the decarburization by executing the reduction so as to realize the prescribed (T, Cr) in the melting-reduction process of Cr, and specifying the slag basicity during blowing and before tapping in the decarburization and blowing process. CONSTITUTION:The molten pig iron containing nitrogen is charged into the refining furnace of a top-blown converter type. Cr ore, carbon or the like are charged thereinto, oxygen is blown from the top-blown oxygen lance, and the stirring gas such as N2 or CO is blown from the bottom-blown tuyere to melt and reduce Cr. After removing slag and tapping, the molten pig iron containing Ni and Cr is obtained. The molten pig iron is charged into the converter and blowing is executed for decarburization. Melting and reduction of Cr is executed so as to obtain the relationship of (T, Cr)<=1.0wt.%, and the slag bacicity during blowing and before tapping in the blowing and decarburization process is made <=1.5. Slag is removed so that the amount of the residual slag may be <=20kg per ton of the molten steel. This constitution lowers the slag bacicity during decarburization and before tapping and reduces the amount of coal to be charged, and facilitates the slag treatment after tapping due to prevention of Cr<6+> from being generated.

Abstract: PURPOSE:To extend the effective portion of a lighting tool, by mounting an auxiliary lens, which makes light rays incident to an inward curved portion by receiving light rays reflected by a focal line type reflection portion, near an inlet of the inward curved portion shaped to the side rear of a lighting chamber. CONSTITUTION:Light rays made incident to a reflector 4 from a light source 1 is made incident to a light guiding lens 5, and each incident ray is refracted or reflected in the light guiding lens 5 and emitted to the lens 7 side of an inward curved portion 3. In this case, light rays made incident to the light guiding lens 5 are divided into light rays, which advance in the lens 5 and are directly radiated from a prism portion 53, and light rays, which is emitted from another prism portion 53 while repeating total reflection in a total reflection portion 54 and an internal flank of a refraction portion 52. Thus, since approximately most of light rays made incident to the lens 5 are radiated to the inward curved portion 3 and the lens 5 ranges over the approximately whole inward curved portion 3, light rays surely enter a front lens 7.
