Title: Protective apparatus for electric motor vehicle and protecting method therefor
Inventor: OBARA SANSHIRO
IPC: H02P27/08
Filed: 1994-11-07
Abstract: PURPOSE: To allow a controller to normally raw a car by another control system even when a sensor, etc., becomes defective. CONSTITUTION: Current control means 70 sets the output limiter of the means to zero when the fault of at least one of a current senior 7, a speed sensor 6 or an accelerator sensor 8 is detected, and generates a voltage command based on the backup control voltage to be output from AC current command generating means 80. PWM signal generating means 90 generates a PWM signal for controlling an inverter 3 by using the voltage command. If the fault occurs in the speed sensor, the current sensor or the accelerator sensor, a backup control voltage v1 is output as an abnormal signal from a backup control circuit 40. As a result, a backup circuit 60 sets the output limiter of the current control circuit to zero, and switches the control signal to the inverter from a vector control so far to a V/f voltage control.

Title: Housing information transmission equipment
Inventor: KONDO YUJI
IPC: H04Q9/00
Filed: 1986-11-14
Abstract: PURPOSE:To satisfy the transmitting condition of transmitting information by the use of a transmission path by deteriorating the average level of an information transmission code lower than the level of the selection code of a management center when the information transmission code is inputted. CONSTITUTION:The telephone number of the management center is transmitted from a dial signal generating circuit 64, and for instance, the PB code of the level of -4dB is transmitted to the management center from a pat switching circuit 68. When a center signal detection circuit 63 detects an information request code from the management center, the information transmission code is generated from the dial signal generating circuit 64 to transmit the transmitting information such as the periodical meter inspection information for gas to the center. The PB code generated from the circuit 64 at that time goes to the PB code of the level of -8dB half of the selection code, since the information transmission signal is inputted to an inverter 68a from a CPU 5. And the average level of the information transmission code can be deteriorated lower than the level of the telephone number of the management center and transmitted to the management center by the pat switching circuit 68.

Abstract: PROBLEM TO BE SOLVED: To easily and inexpensively form an electrification preventive film having durability, and remove pollution by baking it by applying a solution by dissolving transparent conductive metallic oxide particulates in alcohol of an ethyl silicate, to a cathode-ray tube. SOLUTION: An electrification preventive film 2 is formed on a panel surface of a cathode-ray tube 1, and is connected to the earth through a reinforcing band 3, and 0 electric potential is kept over the whole surface. Here, first of all, a solution by dissolving transparent conductive metallic oxide particulates in alcohol of an ethyl silicate, is dripped on a panel surface of the upward turning cathode ray tube 1. Next, the cathode-ray tube 1 is rotated, and it is thinly and uniformly coated with the solution, and is heated, and is dried, and is also baked. Therefore, the metallic oxide particulates become SiO2 by heat treatment, and are fixed to the panel surface, and form the electrification preventive film 2. In this way, direct coating becomes possible, and a film having durability can be easily and inexpensively formed, and electrification of high electric potential is removed.
