Title: Spring clamp
IPC: B60G15/06
Filed: 1987-12-04
Abstract: A spring compressor for large coil springs especially for motor vehicle axle springs comprises first and second disc-like pressure plates which are located at spaced locations along the axis of a cylindrical guide tube and each has a central bore opening. A threaded spindle has a spindle head with a key profile and it is rotatably mounted in an axial thrust bearing of the cylindrical guide tube. The guide tube has a radial support surface on which one of the pressure plates is supported. A cylindrical threaded tube has internal threads insertedly engaged with the threaded spindle and the spindle is connected to the guide tube with an axial mobility so as to rotate with the guide tube. The threaded tube has an end which faces away from the spindle head which has a plurality of radial fingers which fit into corresponding recesses formed in the first pressure plate which includes radial enlargements which form passages for the radial fingers carried by the threaded tube. The fingers of the threaded tube are at least three in number and are substantially wedge-shaped radially extending fingers which taper in a direction away from the spindle head and they engage in a corresponding number of recesses of the second pressure plate. The pressure plate is also provided with enlargements between every two recesses and are countersunk on the exterior of the pressure plate and have diagonal faces shaped so that no planar support surface is present for the fingers outside of the recesses.

IPC: C08J9/20
Filed: 1987-01-19
Abstract: A process for producing expandable styrene-based 
polymer beads comprises adding a low temperature poly­
merization initiator decomposable to half at a temperature of 
from 50 to 80°C for a period of 10 hours to an aqueous 
medium having suspended therein blowing agent-containing 
expandable styrene-based polymer small particles whose 
sizes have been adjusted so as to have a distribution within a 
mean particle size ±20% in a proportion of at least 1/2 the 
amount required for polymerization of a styrene-based mon­
omer to be added to the system, adding a blowing agent in an 
amount to inhibit expansion of said expandable particles 
while the system is heated to a temperature for first stage 
polymerization, continuously or intermittently adding thereto 
a styrene-based monomer to which the rest, if any, of said 
low temperature initiator and a high temperature polymeriza­
tion initiator that is decomposable to the half at a temperature 
of from 80 to 120°C for a period of 10 hours have been added, 
adding blowing agent in an amount for desired expansion of 
the resulting expandable beads, effecting first stage poly­
merization at a temperature from 10°C lower than the dec­
omposition temperature of said low temperature initiator for 
obtaining a half-line of 10 hours to 20°C higher than said dec­
omposition temperature, and subsequently effecting second 
stage polymerization at 100 to 150°C.  
     The process makes effective use of expandable styrene-­
based polymer small particles obtained by suspension poly­
merization in the presence of a blowing agent whose particle 
size is unsuitable for use as expandable beads. The resulting 
expandable beads have a desired particle size with a narrow 
size distribution.

Patent EP-0257819-A3 (EP)
IPC: H04N1/401
Filed: 1987-07-29
Abstract: A laser scanning apparatus is provided with a 
compensating arrangement whereby deviations of a synchronous 
drive are compensated for by adjusting the frequency with which 
the laser beam is modulated. The laser beam is directed 
onto a rotatable spinner (10) which causes the laser beam to scan 
a synchronized moving medium in a number of sequential 
and parallel lines, each of which is determined during a 
cycle of the movement of the spinner. The spinner is driven 
by a synchronous motor. During each cycle, a period error 
is measured to determine a compensating signal which is held 
for the next successive cycle and is used to control the 
frequency of a variable oscillator (62) which determines 
the clocking rate at which information is employed to modulate 
the laser beam. According to the method of the invention, 
lines of information are placed on a synchronized moving medium 
responsive to the aforesaid laser beam during successive cycles. 
The method involves modulating the laser beam in accordance 
with the information and at a frequency which is modified 
for each cycle in accordance with the deviation of the preceding 
cycle with respect to a characteristic normal time period.

Patent EP-0320111-A3 (EP)
Title: Multiple output field effect transistor logic
IPC: H03K19/096
Filed: 1988-11-03
Abstract: In MOS logic circuits with a non-complementary circuit structure 
(for example, dynamic CMOS), a prior art logic gate generated only 
a single output signal. However, the logic tree often implements 
multiple functions, with one function being contained within 
another function. With prior art logic, if two or more of these 
functions are needed as separate available output signals, they have 
to be implemented in several separate gates. The present invention 
utilizes intermediate functions (10) within the logic tree, 
providing gates having multiple outputs. Therefore, the present 
invention reduces the replication of circuitry, thus reducing 
circuit device count. The advantages include reduced integrated circuit 
chip area, speed improvement, and power savings, due to the reduction 
of device count and the corresponding reduction in wire lengths and 
output loading, etc.

Title: Optical memory system
IPC: G11B7/085
Filed: 1989-07-10
Abstract: An optical memory system comprises light beam 
generating means for generating a plurality of light 
beams; a recording medium comprising a plurality of 
guide grooves for guiding each of the light beams, and 
ID sections utilised for identifying a guide groove on 
which each of the light beams is projected; a 
plurality of photo-detectors for detecting the 
intensity of the reflected light or transmitted light 
of each of the light beams projected on the recording 
medium; a plurality of comparators for converting a 
signal released from each of the photo-detectors into 
a binary signal; a majority logic circuit for issuing 
a signal whose level is equivalent to the levels of 
the signals released from the majority of the 
comparators and a moving amount detector for detecting 
the moving amount of the said light beams by counting 
the number of pulses in the pulse signal released from 
the majority logic circuit when the light beams move 
in a direction perpendicular to the guide grooves. 
This optical memory system is designed such that at 
least either the plurality of light beams or the 
plurality of ID sections of the guide grooves are so 
arranged that at least more than half of the light 
beams or more than half of the ID sections are not 
 
 
overlapped in a parallel direction to the guide 
grooves whereby the number of light beams projected on 
the ID sections at the same time is limited to less 
than half of the total number of light beams projected 
on the recording medium. Accordingly, even when the 
light beams are moved in a perpendicular direction to 
the guide grooves, the number of pulses in the pulse 
signal is not influenced by ID signals or the like but 
coincident with the number of the guiding grooves 
through which the light beams have actually passed. 
With use of the optical memory system having such an 
arrangement, the accurate moving amount of a light 
beam is obtained resulting in high accuracy of access 
operation.

positions covering and uncovering the container. A U-shaped member (100) 
having legs is pivotally mounted on the lid flange and is adapted to 
pivot with its legs across the elongated slot near one of the 
enlargements to help keep the rod linkage from inadvertently 
slipping out of the enlargement and into the channel of the slot
