Abstract: A color image forming apparatus capable of efficiently sensing a color deviation and accurately correcting for it is disclosed. The apparatus includes mark sensing device for sensing register marks on a conveyor belt for determining deviations between colors, a first storage device for storing data representative of the results of past color deviation sensing operations, a recognizing device which recognizes a condition inside the apparatus (e.g. temperature), and a second storage device which stores deviations sensed by the mark sensing device and the apparatus condition in which the deviation occurred. The apparatus will correct for a color deviation on the basis of the stored data in the first storage device. In addition, the timing for executing a sensing operation is determined on the basis of the data stored in the second storage device. Thus the apparatus can execute efficient correction with a minimum frequency of correction in accordance with the variation of the above stored data.

Abstract: In an engine provided with a starter motor for putting the teeth of the starter pinion into the teeth of the ring gear coupled with the crankshaft, the apparatus is intended to detect continuously the rotating direction of the engine in a limited range. A magnetic sensor for outputting a signal depending on the passing of teeth in the specific range of the ring gear is provided. This specific range is determined so as not to overlap with the wear region of the ring gear worn by engagement with the starter pinion, so that the detecting precision of angle is enhanced by preliminarily eliminating the effect of the wear of the teeth of ring gear on the angle detecting precision.

Abstract: A mounting support device allows workpieces to be attached at points intermediate between discrete positions of fixture bases of machine tools. The mounting support device has three support members. A lower support member is slidably attached to an intermediate member allowing the intermediate member to move along an x-axis.

Abstract: An image processing apparatus eliminates a detection error in a color offset detecting operation due to a periodic fluctuation in a speed of a conveying belt which conveys a transfer sheet on which color component images are transferred and superimpose to form a multi-color image. A plurality of image forming units are arranged along the conveying belt, each of the image forming units transferring a color component image on the transfer sheet and also transferring a register mark on the conveying belt. A register mark detecting sensor located along the conveying belt detects the register mark on the conveying belt. A distance between the register mark detecting sensor and one of the plurality of image forming units adjacent to the register mark detecting sensor is a multiple of an integer of a circumference of the drive roller. A distance between adjacent ones of the plurality of image forming units is a multiple of an integer of the circumference of the drive roller.

Abstract: An electrically writable nonvolatile semiconductor memory device capable of writing data to any desired threshold value accurately without resorting to a write confirming operation is disclosed. The memory device senses a current flowing through a memory cell transistor while effecting a writing operation. When the current reaches a preselected value, the memory device stops the writing operation. A relation between a desired threshold voltage and the current to flow through the memory cell transistor during wiring is determined beforehand. This eliminates the need for the confirmation of the threshold voltage relying on a reading operation, and allows a desired threshold voltage to be set rapidly and accurately.

Abstract: A machining device has a base and a fixture. The base is fixedly attached to a pallet or a machining table. The fixture is mounted on the base, contacting the base only at projecting contact surfaces which project above the mounting surface of the base. Cleaning of the base before a fixture is attached is done efficiently because only the minimized projecting contact surfaces area between the base and the fixture needs to be cleaned to permit stable contact between the base and fixture. The base and fixture also include projections and holes for precisely aligning the base and fixture with respect to each other.

Abstract: In a semiconductor device having "N" input terminals, a high voltage for a mode switching is applied to a first input terminal, and mode setting information is supplied to the other input terminals. A latch circuit holds the mode setting information supplied during a predetermined period of time starting from application of the high voltage to the first input terminal, during a period of time in which the high voltage continues to be supplied to the first input terminal. Thus, a test is performed on the basis of the mode switching instruction held in the latch circuit and data applied to the other input terminals. On the other hand, if the high voltage is disconnected, the latch circuit is reset.

Abstract: The non-volatile semiconductor memory disclosed includes an X-decoder and word line potential supply circuits, and a current setting/holding circuit. The X-decoder and the word line potential supply circuits set all word lines ground potential in the flash erasing operation, to a predetermined first over-erasing judgment reference potential in an "on" cell detecting operation, and to a predetermined second over-erasing judgment reference potential for judgment of over-erasing deeper than the first over-erasing judgment reference potential and, in an "on" cell specifying operation, set predetermined selected word lines to the first over-erasing judgment reference potential while setting other word lines than the selected word line to the second over-erasing judgment reference potential. The current setting/holding circuit sets the reference current in an "on" cell specifying reference current setting operation such that the result of the check by a sense amplifier is "on".

Abstract: Described is a fragrancing composition having fragrancing components that are not activated until, e.g., application to the skin of a human. The composition is alkaline or (if anhydrous) capable of producing an alkaline pH when in contact with water, prior to application, and includes (1) a vehicle such that when the composition is in contact with water, prior to application, the composition is at an alkaline pH; and (2) at least one potential fragrance that is at least one compound having little or no odor in the alkaline composition but which, e.g., is hydrolyzed in a lower pH environment to produce compounds having a relatively strong aroma. Upon application of the alkaline composition to the skin surface, the strong buffering capacity of the skin (the surface of which has a normal pH of 5.5-7.0) neutralizes alkalinity of the composition (lowers pH) so as to restore normal skin surface pH; the potential fragrance is then hydrolyzed at the lower pH to release the compound having relatively strong aroma.

Abstract: An intermediate transfer unit is constructed by covering a conductive cylindrical base member of drum-shape with an elastic member of belt-shape, the elastic member of belt-shape being adhesively fixed to the base member with an adhesive agent, grooves or pits being provided on the surface of the cylindrical base member, the elastic member of belt-shape being adhesively fixed by the adhesive agent filled in the grooves or pits. The adhesive agent has a resistivity smaller than at least the resistivity of the elastic member of belt-shape. By doing so, it is possible to construct and keep the uniform distribution of resistivity without change by environment and deterioration with age, and to realize proper transferring. Furthermore, since the diametrical change of the drum due to uneven application of the adhesive agent can be minimized, the effect on misalignment in color can be minimized.
