CONSTITUTION:A steel band is r...

The timing control system includes a dummy instruction with the first control field indicating a dummy instruction and the second control field indicating a number of dummy cycles is defined. A decoder detects a dummy instruction by decoding the first field. A counter is connected to the decoder, in which an initial value depending on a value of the second field is set when a dummy instruction is ...

PURPOSE:To simplify an automatic duplex copying work by executing first a reverse side copying of the number of sheets which generates shortage by a jam, storing a form whose one face is copied, in a sub-intermediate tray, changing an original, carrying the form from the sub-intermediate tray to a copying process part, and executing a copying operation. CONSTITUTION:In case when a jam is generated...

PURPOSE:To attain the simple and accurate input of coordinates by means of an ordinary pen or a finger by driving in time series a group of polarizing elements to which the light beams are supplied. CONSTITUTION:A pair of a polarizing element array 10X and a photoreceptor array 12X for input of X coordinates are set opposite to each other on the two counter sides of a rectangular frame. While a pa...

PURPOSE:To perform the input of coordinates with high stability and high accuracy without receiving the effects of the external light, by providing a light shielding means to prevent the external light excepting the light beams from entering a group of photoreceptors. CONSTITUTION:A light shielding means 20 contains a pair of light masking plates 22a and 22b set approximately parallel to the scan ...

PURPOSE:To reduce the variance of the output level of a photoreceptor due to the position shift of a light beam and to attain the stable and accurate input of coordinates, by providing a gradient index lens at the front of a group of photoreceptors. CONSTITUTION:A gradient index lens array 18 is set at the front of a photoreceptor array 12X. The focal points of lenses 18-1-18-n of the array 18 are...

PURPOSE:To attain the input of coordinates with high stability and accuracy by using a correction data storage means and a correction means for correction of the output variance of each photoreceptor. CONSTITUTION:A ROM 32 storing the correction data serves as a correction data storage means. A microprocessor 26 delivers a read address to the ROM 32 with the timing synchronous with the reading of ...

A furnace for manufacturing silicon carbide comprises a broken ring (8) of raw materials in which is embedded a graphite electrical heating element (12). The ring (8) is free-standing and defines a central working space (32) in which is located a support (36). The furnace is enclosed by an annular wall (44) spaced from the ring (8) to define an annular working space. A track (38) is mounted on top...

A new process for the preparation of the known 4'-deoxydaunorubicin and 4'-deoxydoxorubicin is disclosed. The used starting material is 4'-eip-N-trifluoroacetyldaunorubicin which is converted into 4'-deoxy-4'-iodo-N-trifluoroacetyl-daunorubicin from which 4'-deoxy-daunorubicin can be reductively obtained and eventually transformed, by known methods, into 4'-deoxy-doxorubicin.

A probe comprising a nucleic acid fragment covalently linked to an iodinatable residue. Such nucleic acid probes can be readily radiolabeled such as by prelabeling the nucleic acid with a nonradioactive iodinatable residue, and then reacting with radioactive iodine.

PURPOSE:To detect completely the abnormal output of a specific port by integrating the output of the specific port of a microprocessor MPU with no saturation and applying this output to a hysteresis comparator. CONSTITUTION:The output A of an I/O port of a MPU is integrated with no saturation by an integration circuit R'C' having a large time constant. Then this output signal B of integration is s...

This invention is directed to the retreading of steel belted radial tires by removing and replacing more than the protector ply. Initially, the tire is inspected to determine if it is retreadable. The tire is then buffed so that the protector ply will be located and removed. The first working belt is then located and removed. A steel belt incapulated in uncured rubber will be placed on the tire. T...
