Patent JP-H0384396-A (JP)
Title: Heat exchanger
Inventor: ASANO KAZUHIKO
IPC: F28F3/06
Filed: 1989-08-26
Abstract: PURPOSE:To control the reduction of local heat transfer and improve heat exchanging efficiency by a method wherein the slit of an inner fin is cut deeply from a primary lateral wall part into a secondary lateral wall part passing vertically a longitudinal wall part. CONSTITUTION:At a primary longitudinal wall part 3 a fin part 31 and a slit 7 are alternately formed in parallel direction to the flow of supercharged air. At a secondary longitudinal wall part 4 a fin part 4 and slits 8 are alternately formed in the parallel direction to the flow of the supercharged air. Respective fin parts 31 and 41 are securely cut apart by the slits 7 and 8 cut deeply into a primary lateral wall part 5 and a secondary lateral wall part 6 so that there is no such a longitudinal wall part that is continuously connected with the wall parts 3 and 4. Accordingly, flow boundary layers generated at the wall parts 3 and 4 are securely cut apart by respective slits 7 and 8. For this reason, the flow boundary layers are not developed and therefore, the reduction of local heat transfer can be controlled and the supercharged air in a high temp. can be cooled efficiently.

IPC: G03C1/005
Filed: 1988-09-02
Abstract: PURPOSE:To make sampling of an emulsion unnecessary by measuring the viscosity change of an emulsion with time by a torque detector and preparing an emulsion while estimating the grain size of the emulsion according to the detected torque. CONSTITUTION:In preparation of an oil-in-water type emulsion such as a photo sensitive material, a torque detector 7 is installed in a rotating shaft 1a of a high speed mixer 1A and a detected torque value is brought to be taken in a grain size controlling apparatus 8. An aqueous solution and an oily solution are emulsified and dispersed each other and the torque change of the resulting emulsion with time is measured by the torque detector 7. A specified average grain size of the emulsion is estimated from the detected torque, and when the grain size reaches a desired average value, a mixing motor is stopped. As a result, sampling of the emulsion is not needed and emulsifying process is carried out speedily without time loss.

Abstract: PURPOSE:To enable pallets to be individually transported and regulated with respect to their positions by providing slots on both ends of the pallet in the feeding direction and feeding pins and antiskid pins fixed to a feeding lever and by operating with combination of inserting the feeding pins and antiskid pins into the slots. CONSTITUTION:In the transportation of pallets 2 arranged without gaps therebetween, a feeding lever 1 is a bit lifted to insert respective feeding pins 11 into slots 20 in the pallet 2. Since then the total length of the pallet 2 is different a bit from the interval between the pins 11, a gap is formed between the pallets 2 when the feeding lever 1 is moved in the feeding direction to cause the respective pins 11 to come into contact with the pallet 2. The pallet is moved to a predetermined position under such a condition and the feeding lever 1 is further lifted before the completion of the movement so that antiskid pins 12 are located in slots 20 on the front side of the respective pallets in the feeding direction to stop the pallet 2. Next, the feeding lever 1 is lowered to retreat the pins 11, 12. Thus, the pallets can be regulated with respect to their positions and individually fed.
