Title: Turbo compressor
Inventor: BABA TOSHIAKI
IPC: F02C6/10
Filed: 1990-09-29
Abstract: PURPOSE:To enable stable operation even when a flow rate of suppling gas for driving an impeller is changed, by installing a fly wheel coaxially to the impeller, which wheel has a variable inertia moment increased according to increase of rotational speed. CONSTITUTION:In a turbo compressor 1, a fly wheel 2 is rotatably arranged coaxially and integrally to a compressor impeller 2 and turbine impeller 2. Spiral long holes 3 are formed on the fly wheel 2 in a circumferential direction, while a weight 5 supported by a first spring 4 is slidably arranged in each of the long holes 3. When acceleration of starting is settled for the time being, for example, under a high engine speed condition, a centrifugal force applied to the weights 5 is enlarged, the first springs 4 are contracted to balance the centrifugal force. Then the weights 5 are located on positions distanced from a rotational center, and an inertia moment of the fly wheel 2 is increased. Rotational speed of a rotational body 6 is hard to change even in case that a flow rate of exhaust gas from a plant 26 is changed, and thereby the turbo compressor 1 keeps a stable rotational condition.

IPC: B23H1/02
Filed: 1986-10-31
Abstract: PURPOSE:To aim at improvements in machining efficiency and finishing accuracy, by repeating a short between a working electrode and a workpiece and their dissociation, impressing a working voltage pulse train between the working electrode and the workpiece and making it discharge for machining. CONSTITUTION:A working electrode 1 and a workpiece 2 are impregnated in a water dielectric fluid 4, while on the basis of a NC command value 7, machining takes place as repeating a short and their dissociation by a drive unit 8 and a feed motor 6. And, if the short is detected by a gap voltage detector 9 and discriminator 10, a signal generator 11 gives a short-dissociation repetitive command of the electrode 1 to the drive unit 8, while it gives a command to a power controller 13 at that point that an electrode dissociation is detected, then a voltage pulse is added a gap between the electrode 1 and the workpiece 2 from a working power 5 as long as timer duration, thus electric discharge machining takes place. Doing like this, even in case of using the water dielectric fluid, machining efficiency of more than equality to kerosine and accuracy of finishing are securable.

Title: Production of thin web wide flange shape h-beam
Inventor: FUJIMOTO YOJI
IPC: B21B45/00
Filed: 1990-09-28
Abstract: PURPOSE:To produce a thin web wide flange shape H-beam without causing deterioration in material and structure due to flange water cooling and also causing no waviness of a web by previously determining the maximum temp. difference between a flange and a web occurring in the course of cooling down to ordinary temp. with respect to size and cooling water volume density and performing heating so that temp. difference lies within the range free from the occurrence of the waviness of a web. CONSTITUTION:In this invention, at least one or more web heating devices 2 are provided to a thin web wide flange shape H-beam producing line. First, water cooling conditions free from the occurrence of abnormal structure and material in a flange face are computed from size, component, and bloom-passing velocity by means of simulation model, and respective temps. of a flange and a web are determined, by which the required amount of temp. rise of the web is determined from the maximum temp. difference free from the occurrence of the waviness of the web. Subsequently, the amount of applied electric power in web heating is determined. Further, whether buckling is caused or not is checked in the course of web heating, and, in the case of NO, heating is done up to the upper limit, and, as to the shortage, the amount of applied electric power in web heating in a former stage is determined. The above procedures are repeated. In the case where buckling does not occur finally, web heating at one spot suffices but stepwise heating at two spots can be used because of heating capacity. The point is that the production of the thin web wide flange shape H-beam can be done by reducing the temp. difference.
