Title: Controller of electric vehicle
Inventor: MITSUI TOSHISADA
IPC: H02P27/06
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To make an electric vehicle movable even when its monitor device operates abnormally, by making its computer judge the abnormality of its monitor device from the operation of its monitor device or from the own computational result, and by reporting to its driver the abnormality of its monitor device when sensing only the abnormality of its monitor device to continue its motor drive. SOLUTION: In the inside of a monitor-CPU 18, a sensed current value is transferred to a motor-torque estimating portion 42. Further, a torque command value is transferred respectively to a torque comparator 44 and a control computing portion 30, and a motor rotary speed is transferred to the control computing portion 30. From the torque command value and the motor rotary speed, the control computing portion 30 computes a torque current value and an excitation current value to communicate its computational results to a computation-CPU 16. From the sensed current value, the motor-torque estimating portion 42 estimates a motor real torque to transfer its estimating torque value to the torque comparator 44. The torque comparator 44 judge whether the computation-CPU 16 and a motor driver 12 are respectively abnormal or not.  As a result, when only the monitor system is abnormal and the driving system is not abnormal, an electric vehicle can move without help to a safe place or the place of it being repairable therein.

Title: Method and device for dry etching
Inventor: IZAWA MASARU
IPC: H01L21/3065
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To obtain high selectivity ratio on a film of high aspect ratio by a method wherein two or more plasma regions, having different electron temperatures are formed, and the quantity of formed ions and the F with respect to CF2 are controlled independently. SOLUTION: Quantity of ions formed is determined by the electron density in plasma, and the electron density is substantially proportional to the high frequency power to be inputted. Since the dissociation of F/CF2 is generated by the collision of gas molecules and electrons and the electron density depends on high frequency power, the ratio of formation of F/CF2 can be controlled independently of the quantity of ions formed. In a device using an electron cyclotron resonance ECR, a high electron temperature region 103 is formed in an ECR region and a low electron temperature region 102 is formed on the part other than the region. Since the high electron temperature region widens when the gradient of magnetic field is small, the ratio of formation of F/CF2 becomes small, and when the gradient of magnetic field is made larger, the high electron temperature region becomes narrow.  As a result, the ratio of formation of F/CF2 can be made larger, and the processing of a microscopic and deep oxide film becomes possible.
