摘要:
A breathing simulator for use in an evaluation test of respirators is provided, the breathing simulator being able to simulate larger respirations, undergoing a change neither in cycle nor in the amount of ventilation even in a test of respirators having a high pressure drop, able to easily generate not only such regular waveforms as a sine wave, a rectangular wave and a triangular wave but also respiration waveforms of workers and arbitrarily created waveforms as air waveforms, being reduced in size and power consumption, and easy to maintenance. The breathing simulator comprises plural air cylinders (1) for generating an air waveform, a single electric cylinder (2) for actuating the air cylinders, a servo controller (3) for controlling the operation of the electric cylinder, an input/output unit (4) for recording an analog input from the exterior and reproducing the recorded data at an arbitrary magnification, a PC (5) for creating an arbitrary waveform, and a waveform generator 6 for outputting the created waveform.

An electric power steering apparatus is provided which can obtain steering auxiliary power when a steering auxiliary power starting condition is not satisfied and there exists no abnormality in a power source and the like. The electric power steering apparatus controls output of a motor in such a way that through operation of a driver, limited steering auxiliary power that is limited to be smaller than normal steering auxiliary power is exerted on a steering system, and exerts limited steering auxiliary power on the steering system when the vehicle is to be saved, even when due to a vehicle failure or a fuel shortage, the engine stops, so that the load on a driver, which is imposed when the vehicle is moved to a safe place, can be reduced.

Disclosed is a liquid coagulant which can be injected into the inside of a tire without the need of removing the tire from a rim and which can prevent the scattering of a residue of a tire puncture sealing material when the tire is removed from the rim. The liquid coagulant can coagulate an emulsion that contains a natural rubber latex and/or a synthetic resin emulsion. The liquid coagulant contains a foaming agent capable of foaming the emulsion.

A system for decomposing a liquid or gaseous organic compound comprises a ultraviolet decomposition unit and an intermediate product treatment apparatus. The ultraviolet decomposition unit decomposes an organic compound contained in polluted liquid or polluted gas by irradiating ultraviolet rays whose wavelength is less than 300 nm to the polluted liquid or the polluted gas containing the organic compound. An acid electrolytic water feed pipe and an alkali electrolytic water feed pipe are respectively connected to the intermediate product treatment apparatus through valves to neutralize an intermediate product, which results from decomposition of the organic compound, for decomposition by selectively adding strong alkali electrolytic water and strong acid electrolytic water to the polluted liquid or the polluted gas containing the intermediate product.

An electric power steering unit includes: a steering mechanism for steering a wheel under the torque of a steering wheel; a motor for adding a steering assist power to the steering mechanism; a controller for controlling current to be conducted through the motor in accordance with a steering state; a storage element for storing a state of the controller; and initial value setting device for causing the storage device to store a state of the controller when IG (ignition switch) is changed to OFF, and for obtaining a process of overheat state of the controller or the motor to set an initial value of a current limit value to the motor when the IG is changed to ON. As a result, not only a load on a battery when IG is OFF is reduced but also the motor is efficiently driven at the start time.
