Abstract: PURPOSE:To enable the improvement of heat transfer performance by a method wherein first flow path is formed in the fine tubes of the group of fine tubes, in which a plurality of fine tubes are neighbored and connected, and a space between the fine tubes while second flow path is formed in the outer periphery of the groups of fine tubes, in the heat exchanger for car cooler or the like. CONSTITUTION:The first flow path, through which fluid B flows, is formed by the groups 1 of fine tubes, in which the round tubes, made of aluminum, copper or the like, are arranged in checkerboard pattern and are bonded or welded with each other. On the other hand, the second flow path, through which the fluid A flows, is formed by the outer walls of the group 1 of fine tubes and side wall plates 2.

Title: Method of controlling rotational speed of internal-combustion engine
Inventor: ISOBE TOSHIAKI
IPC: F02D41/00
Filed: 1983-07-12
Abstract: PURPOSE:To prevent drop of an engine rotational speed and stall at transition, by increasing an amount of air bypassing a throttle valve over a target amount of air under load upon receiving a load and decreasing the amount of air to the target amount at a fixed rate. CONSTITUTION:A target rotational speed NF according to an operational condition and an estimated duty ratio De according to an estimated amount of air are set. When an ISC timing is reached, an average value NE of an engine rotational speed is calculated, and a basic duty ratio Do for feedback controlling the average value NE to the target rotational speed NF is calculated. When a load is received, the estimated duty ratio De for feedforward control is added to the basic duty ratio Do to determine a control duty ratio D. If a feedback control condition is established, an opening degree of an ISC valve is controlled by the control duty ratio D so that the average value of the engine rotational speed may become the target rotational speed.

Title: Carrier separating method for biological reaction tank using carrier combinedly
Inventor: SAKATA YOSHIHARU
IPC: C02F3/12
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To eliminate trouble generated by the sedimentation of a microbe adhered carrier by setting the density of the microbe adhered carrier to be precipitated at the rising speed of treated water at overflow outlets (carrier separating sections) of respective biological reaction tanks. SOLUTION: As far as the density of a microbe adhered carrier is in the given range, no particular restrictions are set, and a carrier can be a polymer containing gels or the like, and from the viewpoint of mechanical strength, a carrier composed of polyolefin foamed body such as polypropylene or polyethylene and having the density adjusted by, for example, an inorganic filler such as calcium carbonate and provided with the density of approximately 0.95-1.10 g/cm<3> is used. The density of the carrier is determined by the relation with the rising speed of treated water in a carrier separating section 4 of the biological reaction tank. Namely, when the rising speed is large, the density is set large, while the rising speed is small, the density is set small.  As the oxygen feed speed is large and also the nitrification speed is large and the sedimentation of the microbe adhered carrier is not generated, the continuous operation can be carried out for a long period of time.
