摘要:
A magnetic bubble memory device according to this invention comprises a plurality of minor loops, a read-out major line is disposed at one end of the minor loops through gates having a replicating function, and a magnetic bubble detector which includes a detecting line is disposed at one end of the major line. Further, a propagation length from the other end of the read-out major line to the detecting line of the magnetic bubble detector is set at a bit length which slightly exceeds four times the number of the minor loops. For this reason, a continuous read-out operation at high speed is permitted without the influence of replicate pulses.

摘要:
An electronic apparatus has a plurality of operating systems. The apparatus includes a setting unit which preselects a program to be displayed or recorded under control of a first operating system, and a notifying unit which makes a notification as to whether the setting unit preselects the program while an application program is being executed under control of a second operating system.
摘要:
Dedicated registers are arranged in a status LCD control gate array connected to a system bus, and the dedicated registers or register group and a keyboard controller are connected through a keyboard interface bus. The keyboard controller has two ports for communicating with a CPU. The keyboard controller transfers existing commands released to an application program or the like and transmits normal key data through the system bus. The keyboard controller transmits hot key data and transfers a command for realizing any other special function through the keyboard interface bus and the dedicated registers.
摘要:
Benzophenone derivatives expressed by the following general expression (1):A(C--B).sub.n (1)wherein A in the above general expression (1) is a residual group obtained by removing one hydroxyl group from sugar or sugar alcohol, andB is a benzophenone group shown by the following general expression (2) ##STR1## wherein R.sub.1 through R.sub.10 each is expressed by hydrogen, hydroxyl group, an alkoxy group, or the aforesaid binder C, and at least one of them is the binder C. In the case of an alkoxy group, preferably the number of carbon atoms is 1 to 4.C is equivalent to --O--R-- (O is oxygen, R is a fatty chain, and the number of carbon atoms therein is preferably 1 to 4), or 1 mole of glycerin with one hydroxyl group therein bound to A and another hydroxyl group to B. The benzophenone derivatives according to the present invention have excellent capability to absorb ultraviolet rays as well as high compatibility with polar solvent. Also the external preparation for skin in which the benzophenone derivatives are mixed can be mixed in a polar base with wide availability for industrial purpose.
