Abstract: During reading process, an image reading unit read a white pressing plate (reference member) under a state where no original exists between the white pressing plate and an original glass plate. On the basis of the read image data, it is judged whether dirt is detected on the glass plate or not. If dirt is detected, a page in which a black line appears is determined. Information of the page is displayed on a display section. An original of the page is reread by the image reading unit.

Abstract: An output limitation warning lamp is turned on when a possible output Qf of the fuel cell is less than a predetermined value L2. The output limitation warning lamp is provided at a combination meter in an instrument panel. The output limitation warning lamp is also turned on when a possible output Qb of the secondary battery is less than a predetermined value L3. Furthermore, the output limitation warning lamp is also turned on when an allowable drive output Qh, which is the sum of the possible output Qf of the fuel cell and the possible output Qb of the secondary battery, has been less than a required output Ed* calculated at a step before carrying out output limitation to more than a certain extent for longer than a predetermined length of time.

Abstract: An abnormality detector apparatus for an engine water-cooling apparatus has an electronic control unit (ECU) for precisely and quickly determining and detecting an operation abnormality of a thermostat or a water temperature sensor. After the engine is started, the ECU calculates, over time, an engine heat generation quantity, an estimated cooling water temperature or the like on the basis of various engine operating condition parameters, such as cooling water temperature, intake temperature, engine revolution speed, amount of intake air, and the like. After the elapse of a predetermined time, the ECU compares the estimated cooling water temperature and the cooling water temperature actually detected by the water temperature sensor. If the relationship therebetween meets a predetermined condition, the ECU determines whether there is an abnormality in the operating condition of the thermostat and/or the cooling water temperature sensor.

A well brick is disposed on a bottom of a vessel for molten metal, and comprises a product formed into a shape of a cylinder or a frustum of cone by using an isostatic press. The well brick is made by mixing a raw material comprising aggregate of Al.sub.2 O.sub.3 as a main element, 0.3 to 10.0 weight % carbon material, 0.2 to 0.5 weight % metal or metallic powder of at least one element selected from the group consisting of Al, Mg, Ca and Si, and 0.1 to 30 weight % Mg and thermosetting resin as a binding material and by forming them.

Abstract: A stylus for a capacity change detection type disc system which reads information signals such as audio or video signals out of a track which is formed in a disc surface as an arrangement of pits corresponding to the information signals has a body portion which is made of a diamond. Argon plus ions are implanted in the stylus body portion from the surface of the diamond portion to graphitize the diamond to provide a conductive layer which serves as a detecting electrode portion. The graphitizing rate is highest at the surface portion of the electrode portion which consists of the formed conductive layer. The graphitizing rate changes from the surface portion toward a portion remote from the surface portion, where the graphitizing rate is lowest, with a variation rate smaller than that of the graphitizing rate which would result from a single implantation of ions into the diamond.

Abstract: A ferrite core magnetic head useful in a video tape recorder is reinforced in regions near its magnetic gap by the application of a filling material which is a mixture of a glass composition such as a lead glass and a powdered electrically conducting and nonmagnetic material such as a conducting metal oxide or a metal. In thermal expansion coefficient, the glass for the filling material must be comparable to the core material of the head. The use of this filling material precludes cracking of the core by heat treatments during fabrication and deposition of dust on the head surface during operation.
