Title: Variable-voltage variable-frequency controller
Inventor: TOYODA EIICHI
IPC: B60L9/18
Filed: 1988-12-02
Abstract: PURPOSE:To bring a train automatically into highest speed operation mode through a controller by employing a value corresponding to a highest speed limit signal, e.g. an ATC signal, as a target speed thereby bringing the train speed, as close as possible, to a limit speed. CONSTITUTION:The ratio between a train speed signal Vo and an output from a speed sensor 3 is obtained through a wheel diameter coefficient detecting section 9. Outputs from the detecting section 9 and the speed sensor 3 are fed to a wheel diameter correcting section 10 and the output from the speed sensor 3 is converted into a train speed. On the other hand, a speed pattern generator 11 for generating a target speed based on a highest train speed limit signal S is provided. Then a current value corresponding to necessary drive force is produced through a constant speed current pattern generator 12 based on the difference between the output from the generator 11 and the output from the wheel diameter correcting section 10.

IPC: H01L21/86
Filed: 1986-12-19
Abstract: PURPOSE:To form a magnesia spinel film having a substantially stoichiometric composition, when the magnesia spinel film is formed on a single crystal silicon substrate by an electron beam evaporation method, by using a mixture of magnesium oxide and alumina for an evaporating source, and specifying the composition ratio of said mixture. CONSTITUTION:A substrate 2 is a single crystal silicon substrate. An evaporating source 6 is a mixture of magnesium oxide and alumina, and its mixture ratio [MgO]/[Al2O3] is made to be 1.8-3.0. The evaporating source 6 is heated with an electron gun 7 and evaporated. The vapor is partially ionized in an ionizing mechanism 5 before the vapor reaches the substrate 2. The ions are accelerated by a voltage applied on the substrate 2 and made to hit the substrate. Thus a magnesia spinel film is formed. In this way, decrease in Mg component in the vicinity of the substrate can be suppressed. Therefore, the composition ratio in the film can be made to be a value close to the stoichimetric ratio.

The output signals of the subtractor circuit 16 are previously subjected to the correction of the phase quantity via the phase shift circuit 18 and thereafter, the phase thereof is changed only by the phase quantity via the low-pass filter 20. The signals are outputted with the flat phase characteristics in this way. The amplitude characteristics of the reproduction signals SPBIN are so corrected as to attain a peak near the Nyquist frequency (4.7MHz) via the filter 20. The reproduction signals are thereby corrected to the frequency characteristics approximate to the frequency characteristics of an ideal filter as the entire part of the recording and reproducing system and are outputted.
