Title: Finned tube type heat exchanger
Inventor: MATSUSHIMA HIROAKI
IPC: F28F1/32
Filed: 1989-03-27
Abstract: PURPOSE:To eliminate heat conduction between rows of heating tubes in case an operating fluid flowing in said heating tubes has a temperature gradient by selecting plate-shaped fins for slitted fins equipped with slits between rows of the heating tubes and forcing an operating fluid flowing inside the heating tubes to direct at an upper stream side of a heat exchanger fluid flowing on the outside of said fins from its downstream side. CONSTITUTION:An operating fluid which flows into a rear row of heating tubes 4 from an inlet section 8 in the lower part exchanges heat with a heat exchanger fluid by way of slitted fins 3 as it flows in heating tubes 2, and flows to the rear row of heating tubes 4, bend pipes 6 and a front row of heating tubes 4, lowering the temperature gradually, and flows out from an outlet section 9. On the other hand, the heat exchanger fluid absorbs heat from the slitted fins 3 and the heating tubes 2 while it is flowing through the fins, thereby increasing the temperature from TA1 to TA2. Therefore, the differential temperature between the heat exchanger fluid and the heating tubes 2 and the slitted fins 3 is identical with each other substantially, which eliminates heating conduction by way of the front row of heating tubes 5 and the slitted fins 3 for the rear row of heating tubes 4.

Title: Amplifier
Inventor: OOHATA MICHINOBU
IPC: H03G3/00
Filed: 1979-06-11
Abstract: PURPOSE:To prevent the production of transient oscillation in the amplifier and that of interferring voltage to external circuits by clamping the output voltage of amplifier to a given voltage during the period immediately after and before the power down. CONSTITUTION:The reception signal Vin is input to the terminal 11 and fed to the amplifier 12, and no signal Vin is for a certain period. This no-input period is detected at the monitor circuit and the power down command signal PD is fed to the terminal 24. The control circuit 23 of the interface 21 receives the signal PD, the switch switching control signal PS is fed to the switch 22 for closing, and the output of the amplifier 12 is clamped to a given voltage (ground). Next, the circuit 23 delivers the power down command signal PD to the terminal 13 with somewhat delay. When the signal PD is released, the circuit 23 first releases the signal PD, and the switch 22 is OFF with a slight delay than it. Accordingly, the output of the amplifier 12 at the transient period of application of the signal PD and release is clamped at the ground voltage and the interference to the external circuit C is prevented.

Title: Loop pattern detecting system
Inventor: YAMAGUCHI TAKAO
IPC: G03F1/84
Filed: 1983-04-25
Abstract: PURPOSE:To shorten a processing time by noticing on optional one of newly recorded points and when a point connected to the noticed point exists in the lower part of a table judging that the points represent a loop pattern and stopping the process. CONSTITUTION:Noticing on a point A, the point A is recorded on the leftmost position of a table. Then, a point B connected to the point A is recorded on the right of the point A. Hereupon, it is presumed that points connected to the point B are points C and D and they are recorded in the order of C and D. When a point to be noticed is the point C, the point D exists below the point C and the point D is connected with the noticed point C. Therefore, it is judged that the points C-D-B constitute a loop pattern and this process is stopped. In this way the number of data transferring frequency can be reduced and, therefore, the processing time can be shortened.

Abstract: PURPOSE:To reduce the number of parts constituting a drive shaft connecting/ disconnecting mechanism and thereby improve an assembly work by providing a spring member for selectively energyzing a coupling sleeve to the coupling side of both shafts and to the non-coupling side thereof. CONSTITUTION:A connecting/disconnecting mechanism 30 has, as main constituent members, a coupling sleeve 31, an operating rod 32, an operating lever 33, and a compression spring 34. Axial movement of the coupling spring 31 causes coupling of an outer shaft 29b to an inner shaft 29a to be intermittent wherein the sleeve 31 is operated by the operating lever 33 assembled on the operating rod 32. The compression spring 34 is interposed between the outer periphery of the rod 32 and the cylindrical base part 33a of the lever 33, and the lever 33 is energyzed in the direction of movement of the rod 32 due to reaction force of the compression spring. One spring 34 is employed for the above connecting/disconnecting mechanism 30 whereby an operation property is improved together with the reduction of the number of parts and easiness of an assembly work.

Filed: 1981-05-15
Abstract: PURPOSE: To produce a fine powder-free, high-bulk density, particulate product, by coagulating an emulsion latex by injection the latex through a specified orifice into a coagulation solution under specified conditions.  
     CONSTITUTION: An emulsion latex containing particles, particle diameter ≤1μm, is injected into a coagulation solution through an orifice satisfying the condition: L/D≥0.065 Re (where L is the length of the orifice and D is its equivalent diameter) under conditions including a Reynolds number ≤300, thereby forming soft agglomerates 3 consisting of coalesced spheres 1, particle diameter 60W 500μm. The coagulation conditions for these soft agglomerates are strengthened without rupturing the skin 2 by, for example, heating or increasing the coagulation concentration. Then, the skin of an agglomerate having somewhat consolidated spheres 1 is ruptured by a shearing force such as a force of agitation. A  slurry having dispersed coalesced particles 1 is obtained. If necessary, the slurry  is solidified by heating or the like and filtered, washed and dried. It is possible  to obtain a high-bulk density particulate product freed from fine particles and  coarse particles.
