Title: "c" program block annotator
IPC: G06F9/44
Filed: 1990-03-21
Abstract: A programming tool for providing a graphical 
representation of the relationships among a plurality of 
nested blocks integrated into a processed "C" source code 
listing is disclosed. For each line of code including a 
"{" character, an outbound arrow is appended. Similarly, 
for each line of code including a "}" character, an 
inbound arrow is appended, and the inbound and outbound 
arrows are tabbed into vertical alignment. A "depth 
number" is developed for each line now having arrows by 
performing an increment when a line having an outbound 
arrow is encountered and a decrement for the starting 
depth number value of the next line when a given line 
having an inbound arrow is encountered. The depth 
numbers, and also one or more (as indicated by the depth 
number for a given line) right justified vertical line 
segments, are appended to the lines having outbound or 
inbound arrows. Intermediate lines have appended the 
same number of vertical line segments as the last arrowed 
line if it was outbound or one less than the last arrowed 
line if it was inbound. Then, horizontal line segment 
characters are entered in the spaces between the depth 
number and the leftmost vertical line segment in a given 
line having an outbound or inbound arrow.

Title: Gas chromatograph having integrated pressure programmer
IPC: G01N30/86
Filed: 1990-03-21
Abstract: Apparatus and methods are disclosed for performing a 
chromatographic separation of a given compound utilizing programmed 
temperature and mass flow wherein the compound is injected into a 
pressurized carrier gas and passed through a column and wherein a 
portion of the column is subjected to a temperature profile, by 
determining the pressure of the carrier gas and generating a 
pressure information signal representative of such pressure, 
storing desired carrier gas mass flow information and temperature 
profile information, and controlling the pressure of the carrier 
gas in response to the mass flow information, the temperature 
profile information and the pressure information signal, so that 
as the temperature profile information changes with time, the 
desired mass flow of carrier gas at a corresponding time is 
maintained by controlling the pressure of the carrier gas.

Title: Process and device for making plaster elements especially imitation marble with visible faces of high surface quality
IPC: B28B3/02
Filed: 1990-03-30
Abstract: The invention relates to the production of plaster elements having decorative visible faces of high surface quality, widely used in the construction industry. The plaster elements can be made in various configurations, in a single colour or marbled. This is achieved according to the invention by a method in which a multi-layer moulding material consisting of a water/plaster mixture and dried plaster powder is covered in a mould with a hygroscopic and/or open-cell material of low compressibility and then water-compacted by pressure elements with simultaneous removal of air and subsequently compressed with the exclusion of air. A positive pressure is built up in the moulding material and the material covering it and this is maintained at least in part until dimensional stability of the plaster element has been attained. The plaster element is then released with the aid of the pressure elements. The device according to the invention is distinguished by the fact that an upper part is designed as a holder with pressure elements articulated on it on the top and bottom. The lower part for holding the moulding material comprises a dimensionally stable frame with an integrated separating frame and is supported in airtight fashion on the mould bottom. The upper part and lower part can be locked together airtightly via a seal. <IMAGE>

Patent EP-0548828-A3 (EP)
IPC: G11B7/2542
Filed: 1992-12-18
Abstract: The optical data recording media is provided on a 
substrate (1) with a recording layer (3) changing its 
optical characteristic dependent upon difference in the 
heat history, or processes of temperature elevation due to 
laser beam irradiation and the following cooling. The 
media is composed of layered structure not only varying its 
own reflectance or transmittance as an integrated media, 
but also changing the optical phase of the reflected light 
or transmitted light, when the optical characteristic of 
the recording layer is changed. In the method of 
recording, erasing and reproducing data using this optical 
data recording media, when the variations of the 
reflectance is to be detected, recording and erasing are 
effected after temporarily setting the recording layer (3) 
in a state having a higher reflectance. On the other hand, 
when the variations of the transmittance is to be detected, 
recording and erasing are effected after temporarily 
setting the recording layer (3) in a state having a higher 
transmittance. The substrate has such guide grooves that 
the width of either the convex portion between the guide 
grooves or the concave portion of the guide grooves is 
smaller than the diameter of the laser beam spot for 
reproduction.

Patent EP-0733891-A3 (EP)
Inventor: HASHIZUME KATSUSHI
IPC: F02P5/152
Filed: 1996-03-21
Abstract: A preignition detecting system capable of detecting
a preigniting condition (PI) at an early time. Vibration
of an internal combustion engine is detected by a
vibration sensor 113, and is fetched by a controller 12.
The crank angle is detected by a crank angle sensor 111.
It is so determined that PI has occurred when a
difference between the ignition timing and the crank
angle at which the vibration level exceeds a
predetermined level becomes smaller than a predetermined
value. It is further determined that the PI is occurring
when the vibration level continues to increase despite
the ignition timing being delayed continuously, enabling
the occurrence of PI to be detected quickly and reliably.
Furthermore, the constitution is simplified by installing
a first gate that opens after the passage of a short
period of time from the ignition timing and a second gate
that opens thereafter.

Abstract: An improved technique for serializing access to multithreading unsafe resources is
described. A baton manager is used to manage the serializing of accesses to a multithreading
unsafe resource. For a thread to access the multithreading unsafe resource, the thread must
first obtain a baton from the baton manager. Then, once the thread has finished accessing the
multithreading unsafe resource, the thread releases the baton to the baton manager. Hence, by
using the baton manager to manage the baton, accesses to multithreading unsafe resources are
serialized while program crashes or deadlocks are minimized. The multithreading unsafe
resource will typically have a plurality of baton objects associated therewith. The baton objects
are objects of object-oriented programming. The baton manager will permit at most one of the
baton objects for a given multithreading unsafe resource to own the baton at a time. The
threads associated with the baton objects waiting to own the baton must wait until they receive
the baton before they can access the multithreading unsafe resource.
