摘要： In order to carry out commercial synchronous exchange for disconnecting an induction motor from its driving power supply and connecting it to a variable frequency power supply, or commercial synchronous switching for disconnecting the induction motor from the variable frequency power supply and connecting it to a commercial power supply, without any accompanying adverse shock, an induction-motor vector control technique is utilized. A phase-locked loop (PLL) is formed to detect the difference in phase between the output voltage from the variable frequency power supply or the magnetic flux phase of the induction motor on the one hand, and the phase of the power supply voltage on the other, so that the difference in phase thus detected can be maintained at a predetermined value.

摘要： A lower mask layer and a first resist layer are formed on a substrate. The first resister is exposed with the use of an exposure mask having a phase shifter. A part of the first resist layer corresponding to the edge of the phase shifter becomes an unexposed part so that an aperture in slit is formed in the first resist layer by developing. The first mask layer is etched through said first resist layer to form an aperture for forming a gate electrode. A second resist layer as an upper mask layer is formed over the lower mask layer. The second resist layer is exposed with the use of the same exposure mask, and is then developed. By setting the exposure strength to a value lower than an exposure strength for exposure to the first resist layer, a wider aperture is formed in the second resist layer. With the use of the lower mask layer having the narrower aperture and the upper mask layer having the wider upper mask layer, a T-shape electrode is formed.

摘要： A tracking servo system for a magnetic recording and reproducing apparatus uses a flexible magnetic disk having thereon at least first, second and third tracks each of which includes a data track portion and a pair of servo track portions located on both sides of the data track portion. Tracking signals having different frequencies are recorded on the first, second and third servo track pairs. Servo and data heads are formed in a unitary structure. When the data head records an information signal on the second data track portion or reads out the recorded information signal therefrom, the servo head reads out the tracking signals recorded on the first and third servo track portions.

摘要： A hydraulic control device for use with an automatic speed change gear device for a diesel engine using a torque convertor and an auxiliary speed change gear device. This hydraulic control device is provided with a back pressure control valve controlled by means of a throttle pressure developed in response to a throttle opening, wherein when the throttle opening is smaller than a given opening, a pressure oil having a pressure lower than a line pressure is introduced to an accumulator, and when the throttle opening is greater than the aforesaid given opening, a pressure oil having the same pressure level as that of said line pressure is fed to said accumulator to thereby obtain a desired engaging pressure for said automatic speed change gear device, thus effectively preventing a shock due to a change in speed. This device may also be used with a gasoline engine.
