Title: Air-fuel ratio control method for internal combustion engine
Inventor: AMANO MATSUO
IPC: F02D41/14
Filed: 1991-07-12
Abstract: PURPOSE:To reduce fuel consumption in a power operation region and to reduce the occurrence of pollution of exhaust gas by performing logic air-fuel ratio operation in other state than the running-up-a-slope state and the acceleration state of a vehicle on which an internal combustion engine is mounted even when a vehicle is in the power operation region of the internal combustion engine. CONSTITUTION:The air-fuel ratio of an internal combustion engine 1 is detected by a means 3, and various operation states are detected by a means 5. Based on a detecting operation state, a target air-fuel ratio is decided by a means 7 and a fuel feed amount is decided by a means 9. Further, based on a detecting air-fuel ratio and a decided target air-fuel ratio, an air-fuel ratio is corrected by a means 11. Based on a corrected air-fuel ratio, a fuel feed amount is set by a means 13. In this case, even when a vehicle is in the power operation region, such as low rotation and a high load, of the internal combustion 1, when a vehicle on which the internal combustion engine 1 is mounted is in other state than a running-up-a-slop state and an acceleration state, logic air-fuel ratio operation is performed. This constitution reduces fuel consumption in a power operation region and reduces the occurrence of pollution of exhaust gas.

Title: Heat transfer color recording device
Inventor: YAGI TOMOHITO
IPC: B41J13/02
Filed: 1990-06-29
Abstract: PURPOSE:To prevent the positional shift of a colored ribbon and permit a color picture free from out-of-register of the colors to be printed on a recording paper by a method wherein the central part of a reverse roller is made somewhat larger than the other parts thereof and the parts of a feed roller other than its central part and both the ends thereof is made somewhat larger in diameter than the central part thereof. CONSTITUTION:A pinch roller 4 is urged against a feed roller 13 by application of a load to both ends of the pinch roller and, even if the pinch roller 4 is deflected under such a load, its pressing force per unit area is not insufficient as compared to the pressing force at the left and right side thereof due to the division of the pinch roller into two parts sections. By retaining in this way a uniform pressing force against recording paper 11, the trouble of the recording paper 11 being fed with a lateral shifting can be prevented. On the other hand, since the length of the pressing part of the pinch roller 4 against the feed roller 13 is smaller than the width of the recording paper 11 and since there is no difference in feed force between the left and right side of the recording paper 11 due to the division of the pinch roller into two sections, no rotary movement of the recording paper 11 takes place and, therefore, it is fed straight in order to avoid an inexact imposition of successive colors on the recording paper as they are printed over each other.

Title: Radio selective calling receiver and radio-calling system using it
Inventor: UDA YOSHIHIDE
IPC: H04W88/02
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a call disable state and adverse effects on a moving source traffic by enhancing the convenience of the user through automatically revising the position registration. SOLUTION: A pager 100 has a reception function of a radio call signal from each of transmission base stations 104, 105 and a 2-way radio communication function with a personal handy phone system(PHS) radio base station 103. In the case that the pager moves from a pager area A (B), whose position has been registered to another area B (A), a reception frequency of a moving destination is retrieved and the received area ID is collated with a message receptible area ID stored in advance. When the revision of position registration is required, a position registration request is made with respect to radio call exchanges 107, 106 via a PHS radio base station and a public network 108. When the pager is moved to a message reception inhibited area, the transmission of the position registration request is inhibited, and this is informed to the user by means of display or ringing.

Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To decompose water and to generate hydrogen at a relatively low temp. range by applying a high temp. solar chemistry technique by allowing manganese iron oxide to react with a carbonate and water by the use of heat energy such as converged solar energy. SOLUTION: Preferably the manganese iron oxide is MnFe2 O4 , the carbonate is Na2 CO3 and a reaction product is Na(Mn1/3 Fe2/3 )O2 . The powdery manganese iron oxide (manganese ferrite) and carbonate are mixed at a molar ratio of 2:3 and steam is passed there by using a gaseous argon as a carrier at 873 K to generate hydrogen due to the reaction expressed by the formula. When the gaseous CO2 secondarily generated together with the hydrogen is passed through the reaction product at the second stage, an original manganese iron oxide and carbonate are regenerated and oxygen is generated. In this way, the complete closed system of the thermochemical cycle is realized.
