Title: Piston internal-combustion engine with an increased volumetric efficiency by virtue of live gas resonance chugging
IPC: F02B27/00
Filed: 1987-12-30
Abstract: A reciprocating piston-type internal combustion engine includes an intake gas conduit assembly in which intake gas resonance oscillations are generated for increasing the charging efficiency of the cylinders. The intake gas conduit assembly has a feed resonance system including a feed resonator vessel connected with the intake ports of a group of cylinders whose suction strokes do not significantly overlap and a feed resonance pipe communicating with the feed resonator vessel. The intake gas conduit assembly further has an auxiliary resonance system including a closed auxiliary resonator vessel and an auxiliary resonance pipe opening into the auxiliary resonator vessel, an intermediate resonator vessel coupled with the auxiliary resonance pipe and the feed resonance pipe and an intake gas inlet pipe coupled with the intermediate resonator vessel. The feed resonance system and the auxiliary resonance system are tuned to one another by a dimensional selection such that at a predetermined first resonance rpm of the engine the intake gas oscillations generated in the feed resonance pipe and the auxiliary resonance pipe by intermittent suction strokes of the cylinders forming the group are in phase effecting an increase in the charging efficiency and the intermediate resonator vessel is dimensioned such that at a predetermined second resonance rpm of the engine in an operational rpm range the oscillations in the feed resonance pipe and the auxiliary resonance pipe are of opposite phase, effecting an increase in the charging efficiency.

Abstract: A bath, into which water is to be pumped for hydro­
therapy, is disclosed and in which the drain and overflow 
pipes from the bath and the return line to the pump are con­
nected to a junction leading to a waste pipe. A valve in the 
junction directs water from the drain pipe to the return pipe 
but not to the waste pipe while allowing overflow water to 
flow into the waste pipe. After the bath has been used, the 
valve may be opened to drain the bath, drain and return pipes 
to waste.

IPC: H01L23/52
Filed: 1987-03-17
Abstract: A computer-aided automatic wiring method is 
disclosed, which determines a wiring pattern for a 
semiconductor IC device in which function blocks 
(l6, l8, 20, 22) are arranged on a substrate (l0) and 
channels (Cl, C2, C3, C4, C5, C6, C7) are defined 
around the blocks (l6, l8, 20, 22) to serve as wiring 
regions. First, electrical connecting paths between 
associated blocks at one channel (a first channel) are 
determined to obtain a normal wiring pattern in accord­
ance with a bonding request. Subsequently, if another 
channel (a second channel) already subjected to normal 
wiring is present among channels adjacent to the first 
channel, these channels are merged before the next 
channel is subjected to normal wiring, so as to define 
a new expanded channel (a third channel). A combined 
wiring pattern of the third channel, obtained simply 
by combining wiring patterns of the first and second 
channels, is then modified to conform to the shortest 
routing rule. If a vacant space is found in the 
modified wiring pattern the space is removed to reduce 
the size of the third channel. The processing is 
repeatedly executed with respect to every channel, 
thereby optimizing the entire wiring pattern of the 
IC device to maximize its packing density.

Abstract: The movement of a body (1) is determined by mounting 
on or in the body one or more sources (3,4) and one or more 
detectors (12,14) such that each source propagates poly­
chromatic light along a path to a detector. Radiation modula­
tion means (19;25) is supported by the body such that a 
change in the movement of the body causes a displacement 
of the radiation modulation means in at least one light path to 
vary the distributed spectral content of the light reaching the 
detector. The or each detector is adapted to detect the inten­
sity of incident radiation at a plurality of different wave­
lengths, and analysis means (18) interprets the output of each 
detector in terms of the movement of the body.

Abstract: Automated positioning appartus for positioning 
multi-contact components (from 15) on a circuit (on 17) utilizes 
automated members having a high degree of repetitive movement but not 
in themselves accurate, such member realtively inexpensive. A 
positioning member (11) picks up a component and moves it over a first 
viewing head (18). The component is viewed and its orientation 
determined. A viewing head (14) on the positioning member (11) is 
then positioned over a target on a circuit board and its position and 
orientation determined. The results enable the positioning member to 
position the component on the circuit board in the correct position 
and orientation. The viewing heads (14, 18) are calibrated for aspect 
ratio and pixel dimension. Also, the fields of view of the viewing 
heads are calibrated for orientation relative to the positioning 
member (11). The position and orientation of the viewing head on the 
positioning member relative to a pick-up member on the positioning 
member is also obtained.

Title: Mounting structure of a multiple piston ring
IPC: F02B75/02
Filed: 1988-11-29
Abstract: This invention relates to a mounting structure of a 
multiple piston ring for various internal combustion 
engines. A plurality of piston rings (PR1, PR2, PR3) 
are all wrapped in a cylindrical groove formed upon an 
outer surface of a piston (P) so that a gap of one piston 
ring cannot face to a gap (EX1 or EX2) of the other piston 
ring, namely respective gaps of the plurality of piston 
rings are spaced with each other with a certain distance. 
In order to prevent such a facing of two or more gaps 
(EX1, EX2) that may occur due to a rotation of the piston 
rings, a stop pin (3) is mounted on a piston wall so as 
to engage with a gap of one piston ring or formed as a 
convex protrusion on one piston ring so as to engage with 
a gap of the other piston ring. Since respective gaps 
of the piston rings are not faced to each other, it is 
possible to prevent any back pressure gas leakage from 
such gaps of the piston rings.
