Title: Circuit for controlling/driving servo motor
Inventor: BANZAI HIDEO
IPC: H02P29/00
Filed: 1987-01-20
Abstract: PURPOSE:To insulate a controller and a driver by means of an inexpensive circuit component by PWM-modulating a current command signal and then constructing to insulatively transmit it to the driver. CONSTITUTION:A current command signal (a) input from a controller 1 is modulated by a PWM modulator 8 to a pulse signal (b), and transmitted through digital insulating means 9. In a current source 10, a switch SW1 or SW2 is selectively closed in response to the positive or negative state of the transmitted signal (b), and an output current ic or -ic is output. An integrator 13 outputs a triangular wave signal (f) obtained by integrating a deviation between a current command signal and a widing current signal, the signal (f) is modulated by a comparator 14 to a PWM signal (g), and input to a power bridge circuit 3. Thus, an inexpensive circuit component, such as a photocoupler, can be used as insulating means.

Title: Laminated iron core for transformer
Inventor: YAMAMOTO TAKAAKI
IPC: H01F27/245
Filed: 1981-01-29
Abstract: PURPOSE: To decrease the core loss of the transformer by using a directional silicon steel plate having high orientation, magnetic flux density thereof in H=800A/m magnetizing force exceeds 1.88 Tesla, as a leg section and a directional silicon steel plate having comparatively low orientation as a yoke section.  
     CONSTITUTION: The leg sections 1, 2 and the yoke sections 3, 4 are formed to the core of the three-phase transformer. The directional silicon steel plate having high orientation, magnetic flux density thereof in H=800A/m magnetizing force, that is, B8, exceeds 1.88 Tesla, is used as the leg sections 1, 2. The directional silicon steel plate having comparatively low orientation such as a steel plate, B8 thereof is 1.85 Tesla, is employed as the yoke sections 3, 4. Accordingly, the core loss of the three-phase transformer can be reduced up to the same extent as a transformer using only a silicon steel plate having high orientation. The same result is obtained even when the ratio of density b/a and the joining method of a T joined section differ with each other, and the core loss of an intermediate magnetic flux density region is improved particularly more than the case when the silicon steel plate having high orientation is employed independently. Consequently, the transformer profitable in cost can be manufactured.

Abstract: PURPOSE:To make effective and efficient use of exhaust heat energy so as to help to stabilize the regenerative control of hot water and steam by selective switching between lower temperature control and higher temperature control in channeling the heat transfer medium according to its temperature. CONSTITUTION:When the temperature of the heat transfer medium at the exit of an exhaust heat recovery unit 11 is below a specified point, the heat medium is channeled to a lower temperature heat medium system 12 where a heat exchanger 16 directs the heat conveyed by the medium to heating of feed water channeled through a feed water-heating unit 15; the heated water is stored in a hot water-storage tank 25 so that the heat can be utilized effectively. When the temperature of the heat transfer medium at the exit of the exhaust heat recovery unit 11 is above the specified point, the heat medium is channeled to a higher temperature heat medium system 13 where a heat exchanger 18 transfers the heat to a steam regenerative unit 17, converting the heat to steam which is conveyed to a steam-storage tank 31. With the steam regenerative unit 17 connected to the feed water-heating unit 15, the higher temperature heat exchanger 18 converts the hot water obtained from the feed water-heating unit 15 to steam by heating.

Filed: 1989-01-23
Abstract: PURPOSE:To prevent any one-sided contact at time of shift inclination as well as to reduce the extent of vibration by installing an oil separator between an oil recovery part and a discharge pipe, forming a sliding surface between a bearing and a shaft into a spherical surface for fitting them, and forming an oil groove there, while setting a range of primary characteristic frequency in a turning shaft system to be higher, and thereby making improvements in bearing performance at both low and high speed driving ranges. CONSTITUTION:An oil mist flowing on an air current of discharge gas is collected and separated by an oil filter 12, and it is collected on a bottom part of an oil recovery part 10 and, after passing through a spiral oil groove 10c, recovered in an oil sump on the bottom of a case 16, so that lubrication is sufficiently performed even at a high speed range. Since an upper part of a turning shaft 4 is supportable by such a bearing structure as high in reliability, primary characteristic frequency in a shaft system can be set so high, thus even if rotational speed of a compressor is further speeded up, vibration in the shaft system is checkable to be small enough. In addition, if a sliding surface is formed into a spherical surface, the turning shaft is bent to some extent because of centrifugal force by unbalance of a rotator 5a at the high speed range, so that even when the turning shaft 4 is tilted to a third bearing 10e or this bearing 10e is tilted at time of setting, any contact with the sliding surface is kept uniformly, thus any one-sided contact can be prevented.
