Patent EP-0337448-A3 (EP)
IPC: H01L23/057
Filed: 1989-04-13
Abstract: Disclosed is a semiconductor device and its method for 
production in which the Pin Grid Array (PGA) is improved 
so that a plurality of lead pins (7) project from the 
undersurface of a metal stem (1) as a package substrate 
as input and output terminals of a Large Scale 
Integrated-circuit (LSI). The device comprises a 
semiconductor chip (3) mounted on a heat sink (2) to the 
stem (1), a printed circuit board (5) superposed on the 
stem (1) and electrical lead pins (7) connected to the 
outer ends of wiring patterns (4) which are formed 
radially and downwardly projecting through the stem (1), 
and a metal shell (10) assembled to the upper surface of 
the stem (1) and covering the chip (3), bonding wires 
(6) and wiring patterns (4), wherein the patterns (4) 
are formed such that the outer ends of the patterns are 
located within the vicinity over the outermost rows and 
columns of through holes (1a,5a) for connecting lead 
pins (7). Furthermore, in producing the device, a 
central portion palterning wiring layer, which is 
electrically short-circuited for gold plating, is 
provided in order to stabilize the connection with the 
bonding wires (6), and this center layer is cut off 
after the short circuit is performed.

Title: Process and apparatus for rapid solidification of melted ceramic composition
IPC: C04B35/653
Filed: 1989-04-19
Abstract: A novel process for rapid solidification of 
ceramic melts combines certain features of cooling by 
atomization and by contact with chilling surfaces. The 
material to be solidified is divided into fine liquid 
droplets (21) that are propelled by a rapid flow of gas toward a 
rapidly moving chill surface, striking the surface with 
sufficient velocity to flatten each drop into a flat flake-­
like shape, or the temperature of the chilling surface may 
be such as to cause a substantially rounded shape. 
Apparatus for the process (6, 7) is also disclosed. The process is 
particularly applicable to making very fine grained, or even 
amorphous, ceramic materials that can be powdered and then 
sintered into strong, tough ceramic structures.

Title: Loudspeaker diaphragm
IPC: H04R7/24
Filed: 1989-02-21
Abstract: A loudspeaker has a diaphragm 2 made of elastic material 
for example rubber. The diaphragm is under permanent 
tension by virtue of the manner in which it is mounted 
on a peripheral frame 2 and/or by the action of a spring 
5′ pulling the diaphragm centre backwards or pushing it 
forwards. The diaphragm is excited at its centre e.g. 
by a voice coil 3′. Vibrations applied to the centre of 
the diaphragm decrease in amplitude with radius and have 
zero amplitude at the periphery of the diaphragm. As a 
result, destructive interference between the air in 
front of and behind the diaphragm is reduced or 
eleminated and good-quality reproduction of a range of 
frequencies is possible without an enclosure.

Title: Metal gasket for joint structure
IPC: F01P7/16
Filed: 1989-04-19
Abstract: A metal gasket (4) for sealing a three-component joint 
structure in which first and second joint members (1, 2) are 
disposed in confronting relation so as to align their 
respective holes with each other and in which an outer 
peripheral portion of a third joint member (3) is fitted in a 
recess in the confronting surface of the first joint member 
(1). The metal gasket (4) has an opening (4B) and is adapted 
to be placed between the first and second joint members (1, 2) 
so as to align the opening (4B) with the holes of the two 
joint members (1, 2). The metal gasket (4) also has, at a 
position near the opening (4B), a stepped portion (41) defined 
by first and second bends (41a, 41b) engageable with the first 
and second joint members (1, 2), respectively, as the metal 
gasket (4) is placed between the two joint members (1, 2). As 
the first and second joint members (1, 2) are tightened so as

Patent EP-0339952-A3 (EP)
IPC: B27N3/08
Filed: 1989-04-26
Abstract: The subject invention relates to a novel press 
apparatus and method for steam pressing a mat (8) of compressible 
material and an uncured thermosetting binder into a formed 
product and has particular application to the steam pressing 
of lignocellulosic material and a binder to form composite 
board. The novelty resides in making provision for 
projection means (10) generally configured to the outline of the 
end product to be produced and which is carried by a press 
platen, preferably the upper press platen (1), and which is 
intended to impinge into the mat during its compression and 
to effect a steam pressure seal at the impingement area of 
the mat. As a pressure seal of the compressed mat is created 
about the mat edges, steam can then be built up in the mat 
in order to cure the binder. If desired, cool air can be 
passed through the mat after steaming to condense residual 
steam in the mat. The compressed mat after steaming, can 
also be subject to vacuum prior to releasing it from the 
press. The edges of the cured mat which have been subject to 
impingement, can subsequently be trimmed off.

Title: Barrrier means for intraoral radiography
IPC: G03B42/02
Filed: 1989-09-29
Abstract: In oral radiography, there is a risk of 
cross-contamination as a result of inserting and removing 
dental x-ray packets from a patient's mouth. It is 
desired that the risk of cross-contamination be reduced. 
Described herein is an arrangement in which a dental x-ray 
film packet (28) is inserted into a disposable envelope 
(10) prior to insertion into the patient's mouth. The 
envelope (10) comprises a pair of flat, substantially 
rectangular wall members (12, 13) which are joined 
together along three adjacent edges by means of a heat 
seal (14). After the x-ray packet has been inserted into 
the envelope (10), flaps (18, 20) are sealed by means of 
an adhesive layer (26) applied to at least one of the 
flaps (18, 20). Once the x-ray packet has been exposed, 
it can be removed from the patient's mouth and then from 
its envelope (10) prior to normal processing and 
development. The presence of the envelope (10) around the 
packet (28) during exposure prevents contamination of the 
packet (28) itself by saliva-borne microorganisms.
