Abstract: To provide a high-frequency-vibration-assisted electrolytic grinding method and a device therefor in which micro abrasive grains can be used so as to improve the grinding accuracy and efficiency. A high-frequency-vibration-assisted electrolytic grinding method in which a work is grinded by a grinding stone while electrolytic reaction is performed by applying a voltage between the grinding stone and the work through an electrolytic solution and high-frequency vibration is transmitted to the grinding stone or the work wherein; the grinding stone has non-conductive micro abrasive grains with grain sizes of less than #400 in accordance with the JIS R6001 standard of grinding stones for precision polishing projecting from its surface formed of conductive binding material, and the distance between the grinding stone and the work, which is regulated by the projecting lengths of the micro abrasive grains from the base of the grinding stone, is set to less than 0.02 mm.

Abstract: A window display enables a user to easily identify a window to which a selected object belongs. A computer system displays a plurality of windows, each of which includes one or a plurality of objects, and which displays a window to which a selected object belongs. The window field to which a selected object belongs is, in response to the selection of the object, displayed with an attribute, e.g., with a domain (background) color, that differs from that of other window fields. In this manner, it is possible for a user to easily identify the window of the selected object.

Abstract: The present invention provides a scheduler that is able to display two weeks of a last or a next month with the current month with legible fonts. When a zoom key is input by an operator, a monthly calendar is displayed with another week. If a particular date of the month is an early date of the month, one week of the last month is additionally displayed. If a particular date of the month is a late date of the month, one week of the next month is additionally displayed. When a centering key is input by an operator, five weeks are displayed so that a week with a particular date is displayed in the middle of the five weeks.

Abstract: A GUI permits an object to be selected without using a click button, and can be easily operated with few erroneous operations. When a user wants to select an upper scroll button 20, the user brings a pointer 32 in contact with the button 20. When the pointer 32 is moved (step 120) and contacts the scroll button 20 (step 140), the scroll button 20 is reduced by four dots toward the frame side, and the movable range of the pointer 32 is increased by four dots (step 150). The user continues to move the pointer 32 to the scroll button 20 side (step 170). When the pointer 32 contacts the scroll button 20 again (step 190), the scroll button 20 is reduced by four dots, and the movable range of the pointer 32 is increased by four dots again (150). This operation is repeated. Finally, when a count has exceeded a specific value, 3 (step 210), a depression event for the scroll button 20 is transmitted to an application program (step 220), which in turn performs scrolling of the display area (step 230).

Abstract: A control channel junction line system for use with a digital switching network wherein a talking channel used in a control channel is used in a high efficiency is disclosed. Each exchange of the system includes a digital junction line trunk, a low rate information multiplexing trunk, a low rate control channel processing section and a multiplexing/demultiplexing section. When the low rate information multiplexing trunk is connected to a channel on which the control channel is to be carried, one of the circuits corresponding to a time slot used for control channel information is disabled. Upon transmission, the control channel information from the low rate control channel processing section and information from the low rate information multiplexing trunk are multiplexed with each other by and sent out from the multiplexing/demultiplexing section.
