Patent EP-0352532-A3 (EP)
Title: Flat-top valve member for an atomizing pump dispenser
IPC: B05B11/00
Filed: 1989-07-08
Abstract: An atomizing pump dispenser which includes a valve 
member (11) having a flattened top so that the diameter of 
the sealing area (14) in the outlet is increased 
substantially. A recess (21) within the valve member (11) is 
modified to provide conical ball sealing portions (27) 
tapered at predetermined angles to provide a tight seal 
between the ball (23) and the valve member (11). The innermost 
end of an inner hollow part (15) of the valve member (11) is a 
reduced diameter portion (18) such that the initial movement 
of the valve member (11) is easier. This in effect, tricks 
the user's finger by easing the initiation of movement 
of the actuator so as to give the feel of free movement. 
The inner part (15) of the valve member (11) is provided with a 
molded-in slotted protrusion (16) for breaking the seal 
between the valve member (11) and a flexible annular seal, 
thus alleviating the creation of the vacuum caused by 
the seal between the ball (23) and the ball seat.

Title: Vehicular anti-roll system for stabilizing the orientation of a vehicle body
IPC: B60G17/04
Filed: 1989-08-17
Abstract: A hydropneumatic suspension (2) for a left wheel 
and a hydropneumatic suspension assembly (3) for a right 
wheel are connected to each other by means of an anti-­
roll cylinder (40). A sub-tank (26, 27) is connected to 
each suspension assembly (2, 3). A spring constant 
switching valve (24, 25) is disposed between each sus­
pension assembly (2, 3) and its corresponding sub-tank 
(26, 27). The sub-tanks (26, 27) are charged with a 
compressed inert gas. When a vehicle turns, the anti-­
roll cylinder (40) operates so that some of oil is dis­
charged from the inside suspension assembly (2 or 3), 
while oil is supplied to the outside suspension assembly 
(2 or 3). While the vehicle is turning, the spring con­
stant switching valve (24 or 25) for outside suspension 
assembly (2 or 3) is opened, so that the outside suspen­
sion assembly (2 or 3) is caused to communicated with 
its corresponding sub-tank (26 or 27), whereby the 
spring constant of the outside suspension assembly (2 
or 3) is lowered. When the turning movement is 
finished, the spring constant switching valve (24 or 25) 
is closed, so that the suspension assembly (2 or 3) is 
disconnected from the sub-tank (26 or 27).

IPC: B29C44/12
Filed: 1989-09-15
Abstract: The object of the description is a method and apparatus for 
attaching two casing parts (1, 6) elastically to each other. 
The first part (1) comprises a protruding edge (2), which is 
attached to a corresponding groove (7) in the other part (6). 
Liquid plastic foam is first moulded into a mould (3) with a 
cavity (4) corresponding substantially to the form of the 
groove (7), which foam then, solidifies and fixes to form a 
plastic foam list (5) at the edge (5). The cavity of the 
mould has been dimensioned a little greater in width than the 
groove (7). When then the elastic list (5) is pressed into 
the groove (7) the list is attached to the groove through its 
elasticity and the friction force. The plastic foam (5) can 
be e.g. a two-component polyurethane foam.
Patent EP-0399092-A3 (EP)
IPC: C09G3/00
Filed: 1989-09-20
Abstract: A synthetic resin composition having particles of metallic 
gallium or gallium alloy dispersed uniformly in a synthetic 
resin is particularly useful for the production of a surfacing 
material for a glider on snow or ice. This is because when a 
molten paraffin wax is applied to such surfacing material, part 
of the wax penetrates into the sheet to form a gallium-paraffin 
mixture on the surface of gallium particles and at lower snow or 
ice temperatures, the gallium particles expand, and 
as the result of their expansion, gallium particles are held 
strongly enough on the gliding surface of ski to maintain good 
water-repelling and glide characteristics over a prolonged 
period without allowing the gallium-paraffin mixture to come off 
the ski.  
     The composition is also useful for many other similar uses 
such as a plastic gear, a constructional material, a marine 
structural material and the like because of its excellent glide, 
water-repelling and wear resisting properties, which can be 
retained for a prolonged period.

Title: Disk scanning apparatus for batch ion implanters
IPC: H01L21/673
Filed: 1989-05-16
Abstract: A mechanical scanning system for a batch ion 
implanter includes a disk for mounting wafers at 
sites near its periphery and a disk drive assembly 
for rotating the disk. The disk and the disk drive 
assembly are supported in an end station vacuum 
chamber by a scan arm which extends through a sealed 
opening in an access door. A scan drive assembly 
attached to the access door scans the scan arm and 
the disk in an arc-shaped path. Simultaneous 
rotation and scanning of the disk cause the ion beam 
to be distributed over the surfaces of the wafers 
mounted on the disk. A pivot drive assembly rotates 
the scan arm and the disk about a pivot axis between 
an implant position and a load/unload position. The 
implant angle can be changed without opening or 
venting the vacuum chamber by loosening the 
attachment of the scan drive assembly to the access 
door and rotating the scan drive assembly, the scan 
arm and the disk about the pivot axis. The access 
door can be moved on rails to an open position for 
access to the disk.
Patent EP-0343927-A3 (EP)
Title: Image-processing apparatus
IPC: H04N1/405
Filed: 1989-05-23
Abstract: An input gray-scale image is converted to a bilevel 
output signal by an image-processing apparatus with two 
binarizing circuits: one employing a uniform threshold and 
the other a dither matrix. The outputs of these circuits 
are selected for each pixel by deciding whether the pixel is 
a bilevel pixel or a gray-scale pixel. The decision is 
based on the maximum and minimum gray levels in a block of 
pixels centered on the pixel in question. Images having 
both bilevel and gray-scale parts can thus be binarized with 
clean reproduction of black-white edges.

Title: Magnetic disk drive with seal
IPC: G11B25/04
Filed: 1990-04-10
Abstract: A disk drive includes a cast base 5 which supports the spindle 
assembly and the actuator assembly, and a cover 11 that is loosely 
received by the cast base to form the head-disk enclosure. The cover 
is secured and sealed to the cast base by a malleable metal foil tape 
30 that surrounds the enclosure and continuously overlies the interface 
between cover and base. The tape complies with the surface 
irregularities and does not creep, to provide permanent shielding and 
sealing between base and cover. Cable exiting the enclosure is sealed 
using a piece of double sided adhesive between the cable and the 
casting, with the malleable foil tape thereover. Thus no significant 
thickness is added to the enclosure by the tape, which also provides 
noise and EMC shielding in addition to securing and sealing the cover.
Patent EP-0398596-A3 (EP)
Title: Atmospheric optical communication link
IPC: H04B10/118
Filed: 1990-05-11
Abstract: This invention is a mobile, short range, high data rate, high availability 
atmospheric optical communication link which can be used to temporarily 
bridge a break in an optical fiber network. Briefly, the invention comprises 
two transceivers, one at each end of a break, to bridge a severed optical 
fiber via an atmospheric optical transmission path which can extend for a 
distance of roughly 5 miles. A special light source is not required. The light 
transmitted through the atmosphere is the low power light emitted from the 
end of an optical fiber and generated by an optical regenerator normally 
used to generate light only for transmission through an optical fiber. The 
light is first expanded and collimated for atmospheric transmission and then 
transmitted to a receiver. At the receiver, the diameter of the received 
beam is optically reduced by focusing it onto the end of an optical fiber for 
coupling the light into the fiber. The optics for the transmitter and receiver 
can be mounted on a platform that adjusts in real time to optimize the 
signal received. Optical alignment can be automatically maintained by 
computer controlled transmitter steering and receiver tracking. The 
transmitters and receivers require no communication other than the 
incoming beam to maintain optical alignment and does not require 
additional bits in the data stream for telemetry.

Title: Semiconductor memory with a sequence of clocked access codes for test mode entry
IPC: G01R31/28
Filed: 1991-08-12
Abstract: An integrated circuit having a normal operating mode and a special operating mode, such as a special test mode, is disclosed. The special test mode is enabled by a series of signals, such as overvoltage excursions at a terminal, rather than by a single such excursion, so that it is less likely that the special test mode is entered inadvertently, such as due to noise or power-down and power-up of the device. The circuit for enabling the test mode includes a series of D-type flip-flops, each of which are clocked upon detection of the overvoltage condition together with a particular logic level applied at another terminal; multiple series of flip-flops may be provided for multiple special test modes. In addition, sequential codes may be used for further security. Logic for evaluating both a sequence of codes received in parallel from a number of address terminals, and also a sequence of serial codes received at single address terminal, are disclosed. Additional features include the provision of a power-on reset circuit which locks out the entry into the test mode during power-up of the device. Acknowledgment of the entry into test mode is provided by the presentation of a low impedance at output terminals while the device is not enabled; chip enable of the device causes the device to exit the test mode. Once in test mode, the output enable terminal of the device can provide a chip enable function. <IMAGE>
