Filed: 1987-10-07
Abstract: A cleaning method for removing unnecessary matters 
accumulated on a surface on the bottom of a recess so as to 
clean the surface. An adhesive surface (229) on a projection 
projected from an elongated base member (222) is brought into 
contact with the unnecessary matters on the surface to be 
cleaned and is separated forcibly from the surface to be 
cleaned by application of tension to the elongated base 
member (222), whereby the unnecessary matters are lifted off the 
recessed surface to be cleaned. Disclosed also is a 
cleaning cassette (525) for cleaning the bottom surface of a 
recess by removing unnecessary matters from the surface, 
having an elongated tape-like base member (222) carrying a 
plurality of projections each having an adhesive end surface

Patent EP-0301707-A3 (EP)
Title: Apparatus and method for providing an extended processing environment on nonmicrocoded data processing system
IPC: G06F9/318
Filed: 1988-06-30
Abstract: In a data processing system employing microcode 
techniques, complex sequences of microinstructions 
can be initiated by application of a single 
macroinstruction. These complex sequences of 
microinstructions are typically noninterruptible and 
therefore the execution of a macroinstruction is 
atomic (i.e., executed as a single entity). Data 
processing systems that do not employ microcode 
typically have simpler macroinstruction sets that do 
not provide for a similar atomicity for complex 
instruction sequences. In order to obtain the same 
atomicity of instruction execution and to provide a 
nonmicrocoded data processing system with the 
capability to execute complex instruction sequences 
as a atomic operation, the nonmicrocoded data 
processing system is provided with a third mode, in 
addition to the (nonprivileged) user mode and the 
(privileged) kernel mode, of operation that permits 
the execution of instruction sequences with 
interrupting events disabled and certain functions 
and apparatus enabled to facilitate instruction 
sequence execution.

Patent EP-0331162-A3 (EP)
IPC: H04B7/185
Filed: 1989-03-02
Abstract: In a terminal station (11-1), a memory is used 
to memorize a functional mode information signal 
representative of a functional mode which is 
characterized by a specific feature of either hardware 
or software used in the terminal station and in which 
the terminal station is operable. A terminal 
communication section (18) receives a transfer request 
signal from a central control station (10) through a 
radio channel and delivers the transfer request signal 
to a reading circuit. The transfer request signal is 
representative of a request of transfer of the 
functional mode information signal to the central 
control station. The functional mode information signal 
is read out of the memory by the reading circuit and is 
transmitted by the terminal communication section to the 
central control station through the radio channel. In 
the central control station, the transfer request signal 
may be produced by a functional mode information 
management circuit (45). A central communication 
section (14) transmits the transfer request signal to 
the terminal station through the radio channel and 
receives the functional mode information signal to 
deliver the functional mode information signal to the 
functional mode information management circuit, which 
manages the functional mode information signal.

The size of these surfaces is between 0.5 and 2 cm<2>.
Patent EP-0346907-A3 (EP)
Title: Tracking and focus actuator for a holographic optical head
IPC: G11B11/105
Filed: 1989-06-15
Abstract: An actuator for an objective lens (34) in an 
optical head which provides a compact structure that 
does not move the laser beam (29) relative to the 
objective lens in the tracking mode. The low profile 
optical head design is accomplished by designing the 
optical beam path in the same space occupied by the 
tracking and focusing motor (20, 22, 24, 36, 38, 42, 46, 
52; 10, 12, 14, 16, 18, 26, 40). A mirror (48) reflects 
a laser beam (29) from a laser (28) at an angle to an 
objective lens (34). The objective lens (34) and the 
mirror (48) are coupled together in a manner allowing 
movement of the objective lens (34) relative to the 
mirror (48) along the path of a laser beam (29) from 
the mirror (48) to the objective lens (34). The objective 
lens (34), mirror (48) and the coupling mechanism are all 
moved along the path of the laser beam (29) between laser 
(28) and the mirror (48) for tracking control. Because 
the mirror (48) moves with the objective lens (34), there 
is no beam clipping or beam distortion. For focusing, the 
objective lens (34) is moved relative to the mirror (48). 
The laser (28), the detector (58) and their associated 
optics are stationary, with only the mirror (48) and 
objective lens (34) being moved, thus limiting the mass 
moved and the power requirements. The simple structure 
eliminates the need for a fiber optic cable.

order port control units are connected to higher order 
port control units. The port control units of the 
maximum order are connected to the diagnostic processor 
through a similar main port control unit and each of the 
primary control unit are connected to the system units. 
A specific one of the system unit numbers is supplied 
from the diagnostic processor to the primary port 
control units through port control units of the higher 
order control units so as to select a specific one of 
system units as a current diagnosed unit.
