Title: Thermal seed for treatment of tumors
IPC: A61F7/00
Filed: 1989-03-10
Abstract: A heater (seed) and system for subjecting 
tumors to closely controlled hypothermia or higher 
temperatures includes a core of ferromagnetic material 
having a high resistivity or resistivity of a non-­
conductor enclosed with a bio-compatible non-magnetic 
conductive sheath and excited by a coil positioned to 
establish a magnetic field coupled to the seed. The 
core is dimensioned so as to reduce demagnetizing 
effects to acceptable levels. The thickness of the 
conductive sheath is optimized to achieve a heat 
generating capacity which is considerably greater than 
that of the bare ferromagnetic material.

Patent EP-0354639-A3 (EP)
IPC: G05B19/18
Filed: 1989-04-25
Abstract: In a machine tool for cutting a non-circular cross section on a 
workpiece, sensing means are provided to detect the rotational angle 
of the main shaft which rotates the workpiece and the signals thus 
obtained are used to control the longitudinal displacement of a non-­
rotary tool shaft disposed perpendicularly to the main shaft and which 
can advance and retreat axially relatively to the main shaft axis but 
cannot be rotated. An armature on the tool shaft lies between a pair 
of electromagnets that are energized in accordance with the signals 
indicating the rotational angle of the main shaft and thereby the 
tool shaft is displaced longitudinally accordingly. The axial position 
and the speed of longitudinal displacement of the tool shaft are also 
sensed to obtain feedback for stabilizing the travel and positioning 
of the tool.

Title: Object lens driving device
IPC: G11B7/09
Filed: 1989-05-25
Abstract: An object lens driving device causes partial rotation 
of movable members (2, 11) holding an object lens (1) on 
an X-Y frame perpendicular to the optical axis of the 
object lens (1) about a resilient hinge member (16) as the 
fulcrum. The movable members (2, 11) are supported by 
base members (4, 12). The hinge member (16) interconnects 
the movable members (2, 11) and the base members (4, 12). 
The electro-magnetic coils (81, 82, 83, 84) and the 
magnets (65, 66) cause relative rotation of the movable 
members (2, 11) with respect to the base members (4, 12) 
about the hinge member (16) as center. The rotational 
axis passing through the hinge member (16) passes through 
the position of center of gravity of the movable members 
(2, 11) and the balanced position of moment of inertia of 
the movable members (2, 11).

Title: Printer with a printhead adjustment mechanism
IPC: B41J25/308
Filed: 1989-08-15
Abstract: After a printer lid (2) has been opened, when a signal 
indicating that the lid (2) is closed again and a signal 
indicating that there is a sheet in a print mechanism (1) 
are received, the spacing or distance (Δh) between a print 
head (5) and the face of a sheet (P) held against a platen 
(8) is automatically adjusted to a desired value. Therefore, 
when a printing process is to be resumed after the lid (2) 
has been opened during printing operation, the spacing (Δh) 
between the print head (5) and the face of the sheet (P) is 
corrected even if the spacing (Δh) may have been varied due 
to physical contact to the print head (5) or a carriage 
mounting the print head (5) by the operator, so that desired 
print quality will be maintained after the printing process 
is resumed.
