Abstract: A personal computer system enables simultaneous use of a relative-coordinate-mode input device and an absolute-coordinate-mode input device, thereby allowing correct input of absolute coordinate data, such as for characters. A pad-type first input device and a stick-type second input device are provided for a notebook computer. The first input device outputs both absolute coordinate data and relative coordinate data. The second input device outputs only relative coordinate data. When the absolute coordinate data is output, the relative coordinate data format is converted into the same format as the absolute coordinate data, and ID information for distinguishing the relative coordinate data from the absolute coordinate data is added to part of the relative coordinate data format.

Abstract: An information processing apparatus includes tracking process display units representing whether tracking processing functions are available or unavailable, tracking process determining units that determines whether to execute the tracking processes with reference to the tracking process display units, based on input mobile data, that outputs the mobile data when the tracking processing functions are available, and that ignores the mobile data when the tracking processing functions are unavailable, a tracking process executing unit to which the mobile data is input from the tracking process determining units and that executes the tracking processes, and an extension process executing unit which executes extension processes when extension data relating the extension process is input from data input devices.

The USB interface device includes a first-type connector provided to a first surface of a case and/or a second-type connector provided to a second surface of the case opposing the first surface, and a USB hub circuit provided in the case so as to connect the connectors, wherein the first-type and second-type connectors are connectable to each other, and the first-type connector of the USB interface device is connected to the second-type connector of another USB interface device and the second-type connector of the USB interface device is connected to the first-type connector of yet another USB interface device when a plurality of USB interface devices are layered one over another.

Abstract: A coordinate input apparatus for correcting the shift in an input coordinate system between different coordinate input apparatuses relative to an opening of each apparatus. A data processing block captures information from a coordinate detector PD to determine whether a tapping operation has been performed and determine whether the finger is being slid on a sensor board. A data analyzing block compares inputted absolute coordinates (X, y) with minimum coordinate values (Xmin, Ymin) and maximum coordinate values (Xmax, Ymax) indicative of a preset effective pointing area on the sensor board. A control block controls the data analyzing block to transfer replaced minimum coordinate values (Xmin, Ymin), maximum coordinate values (Xmax, Ymax) and the values of absolute coordinates (X, Y) to a data correcting block. Based on these minimum coordinate values (Xmin, Ymin) and maximum coordinate values (Xmax, Ymax), the data correcting block transforms the absolute coordinates (X, Y) into display coordinates.

Abstract: An electronic device having a contact point unit that protrudes from the casing but is protected without the use of a cap is provided. This electronic device includes a contact point unit having at least one contact point protruding from the surface of the casing of the device. This contact point unit includes a main body rotatable supported by a rotational axis extending from both side surfaces of the casing, and at least one contact point attached to the surface of the main body. The main body is rotatively moved so that the contact point moves from a contact point exposing position to a contact point accommodating position. When the contact point unit is not used, the main body of the contact point unit is rotatively moved so that the contact point is accommodated in the casing.

Abstract: The invention relates to a method of preparing 2-chloro-pyridinemethanol represented by the following formula (1). The method includes the steps of: (a) reacting 2-chloro-monochloromethylpyridine with an alkali metal salt of a carboxylic acid and/or a hydrate of the alkali metal salt so as to form an ester derivative; and (b) hydrolyzing the ester derivative so as to form the 2-chloro-pyridinemethanol.

Abstract: The present invention relates to phthalimide compounds represented by the following general formula (I) and their acid-added salts and to methods of producing the same: ##STR1## wherein Y represents --CH.sub.2 --CH.sub.2 -- or --CH.dbd.CH--. The present invention provides phthalimide compounds represented by the above general formula (I) and their acid-added salts, which are useful compounds as intermediates of medicines such as anti-ulcers based on histamine H.sub.2 receptor antagonism. In particular, acid-added salts of the phthalimide compounds can be easily refined by the recrystallization method. Therefore, there is provided an advantage that purity of the anti-ulcers which are derived from phthalimide compounds and their acid-added salts according to the present invention can be improved.

Abstract: 2'-Deoxy-3',5'-diacyl-5-fluorouridines useful as antitumor medicines or intermediates thereof are easily and efficiently obtained by first fluorinating 2'-deoxyuridine in aqueous solution with fluorine gas to thereby form 2'-deoxy-5,6-dihydro-5-fluoro-6-hydroxyuridine, which is a novel compound, and reacting this compound with a carboxylic acid anhydride or halide R--CO--X, where R is an aliphatic group having not more than 20 carbon atoms or a substituted or unsubstituted phenyl group, and X is an acyloxy group RCO.sub.2 or a halogen atom. In the initial fluorination reaction the aqueous solution may contain a carbonate (or a hydrogen carbonate) or a lower fatty acid or its salt to capture hydrogen fluoride formed by the reaction. The next acylating reaction can be promoted by carrying out the reaction in the presence of an organic base such as pyridine.
