摘要： An image forming apparatus usable with a process cartridge detachably mountable thereto. The process cartridge includes a main cartridge containing a photosensitive member and process means as a unit. A subordinate process cartridge is detachably mountable to the main cartridge. The subordinate cartridge includes at least a developing device which is different from the developing device contained in the main cartridge so that a multi-color image can be formed if desired. The photosensitive member is used both for the main process cartridge and the subordinate cartridge.

摘要： Light is emitted to each of right and left eyes, the emission of light is controlled according to light stimulation steps defined by a combination of light intensities and light emission times, and presence or absence of reaction of a test subject to light is detected at the respective stimulation steps. When reactions, the number of times of occurrence of which is a predetermined number of times of occurrence and less, are detected at a given stimulation step, the given stimulation step is regarded as not being viewed, and tests are omitted which would be effected at stimulation steps lower than the given stimulation step by a predetermined number of steps, whereas when reactions, the number of times of occurrence of which is a predetermined number of times of occurrence and more, are detected at a given stimulation step, the given stimulation step is regarded as being viewed, and tests are omitted which would be effected at stimulation steps higher than the given stimulation step by a predetermined number of steps.

摘要： A neodymium/iron/boron permanent magnet is provided with high corrosion resistance by forming a coating layer of a vitrified sodium silicate on the surface. The vitreous coating layer of sodium silicate is formed by coating the surface of the permanent magnet with an aqueous coating solution of water glass followed by drying of the coating layer and vitrification of the dried coating layer by a heat treatment under specified conditions. Characteristically, the thus formed vitreous coating layer of sodium silicate is subjected to a leaching treatment with water at a specified temperature for a specified length of time in order to remove away residual sodium content leachable in water so that the troubles due to absorption of moisture by the alkali constituent in the sodium silicate coating layer can be largely dissolved.

摘要： A rare earth-based permanent magnet such as a neodymium-iron-boron permanent magnet, which is disadvantageous in respect of the low corrosion resistance, can be imparted with high corrosion resistance by providing the surface with a protective coating film of vitrified alkali metal silicate, e.g., sodium silicate, of which the SiO.sub.2 :(alkali metal oxide) molar ratio is in the range from 1.5 to 20. The vitrified alkali metal silicate-based protective coating film can be formed by coating the surface of the magnet with an aqueous coating solution containing sodium silicate to form a coating layer which is dried and subjected to a heat treatment at 50.degree. to 450.degree. C. to effect vitrification of the alkali metal silicate. The thickness of the thus formed protective coating film should be in the range from 5 nm to 10 .mu.m. The protective effect of the vitrified sodium silicate-based coating film can be further improved by admixing the coating solution with finely divided silica particles of 5 to 50 nm average particle diameter.
