Patent EP-0351953-A3 (EP)
Title: Optical head with a tilt correction servo mechanism
IPC: G11B7/135
Filed: 1989-06-16
Abstract: Optical head devices including a tilt servo mechanism 
are disclosed. The tilt servo mechanism uses 
photodetectors 53a, 53b for detecting the rays of light 
reflected from the recording surface of the optical disk 
6; these rays of light for tilt detection are obtained 
from a portion of the light emitted from the laser diode 
1 which constitutes the light source for the information 
reproduction. According to one aspect, prisms 55a, b 
are formed at the flange portion of the converging lens 
5 to refract peripheral portions of the light emitted 
from the laser diode for the purpose of tilt detection; 
according to another aspect, secondary diffraction 
grating domains 3a, 3b are provided at the sides of the 
primary diffraction domain 3c of the diffraction grating 
3 (which resolves the effective or central portion of 
the emitted light into three pencils of rays: the 
central pencil for the information reproduction and two 
lateral pencils for tracking error detection), to 
diffract peripheral portions of the emitted rays of 
light for the purpose of tilt detection; according to 
still another aspect, a mirror 90 is provided to reflect 
 
 
peripheral portions of the emitted rays; and according 
to a further aspect, a mirror 92 is provided to reflect 
the light passing through the beam splitter which 
reflects to the converging lens the light emitted from 
the laser diode. The photodetector receiving the light 
reflected from the recording surface of the disk may be 
partitioned into two detector cells, whereby the tilt 
signal is obtained as the differential output of the two 
cells.

Title: Shielded magnetic assembly for use with a hearing aid
IPC: H04R25/02
Filed: 1989-07-19
Abstract: A shielded magnetic assembly for use in a magnetic hearing aid is described. The shielded assembly uses a disc-shaped magnet (22) with a high permeability, low coercivity material placed on the face of the magnet away from the air gap. Preferably, the shielding material also covers portions of the edge of the magnet to form a cap (24). The shielding focuses the magnet's energy into the air gap to improve coupling and reduce interference from external magnetic fields.
Patent EP-0358410-A3 (EP)
Title: Low cost/power visible light solid state laser
IPC: H01S3/0941
Filed: 1989-08-31
Abstract: A compact, laser diode pumped, high efficiency, 
solid-state laser comprises an output coupler mirror (182) 
forming a front end of a laser cavity. A back end of the 
laser cavity is formed by a rear mirror (172) through 
which emissions from a laser diode (162) pass for pumping 
a laser chip (174) of stoichiometric lasing material. A 
frequency doubler chip (176) is positioned immediately 
adjacent the laser chip to double the frequency of light 
generated by the laser chip and thereby halve its 
wavelength. The laser chip is bonded to the frequency 
doubler chip by coupling material having a refractive 
index matched to the chips to nearly eliminate reflections 
at the bonded chip surfaces. Such bonding increases the 
effective Q of the laser cavity which receives the bonded 
combination of the laser chip and the doubler chip at a 
beam waist defined within the laser cavity by means of 
beam shaping with the laser chip being positioned to 
receive pumping energy from the laser diode through the 
rear mirror of the laser cavity. Spiking or peaking of 
the output laser light is effected by gain switching, 
phase modulation or by imparting vibratory motion to the 
bonded combination of the laser chip and the frequency 
doubler chip.
