Patent KR-840000206-B1 (KR)
Title: Method for moulding a type for a wheel rim
Inventor: KOOREVAAR ARIE
IPC: B29D30/06
Filed: 1981-04-16
Granted: 1984-02-29
Abstract: A tire having a hollow core (8) surrounded by a foamed outer layer is made by locating the core in a split mold (2) and injecting a foamable plastic material around the core and curing it in situation. The mold may be cooled to form a skin on the foam, and may be rotated to aid the even distribution of the foam.  A typical apparatus comprises a split mold, one half of which receives a rim and the core and the other half of which closes to form a cavity with an injection space surrounding the core.  The tires are low-cost and unpuncturable and are suitable for use in low-speed vehicles, such as wheel barrows.

Title: Adjustable folding ironing board
Inventor: WILSON KERMIT H
IPC: A47B5/04
Filed: 1983-01-14
Granted: 1990-05-04
Abstract: The work surface of the ironing board is attached to a frame which can be swivelled by a support between two horizontal positions of use of different heights and a storage position in a wall cupboard. In either position of use the board can be turned by a turntable 24 set between the frame and the work surface and then locked by a ratchet pawl. To adjust the working height of the board there is a guide rod set between the frame and the cupboard fastening where it can be flxed in each upper and lower useful position by locking pivots. These pivots can be manually operated. To lock the board in its position of use there is a pawl which stops the frame from swivelling. This pawl can be released by hand before folding away the board.

Title: Detecting device and method of fast significant sample
Inventor: THOMSON DAVID LYNN
IPC: G10L25/90
Filed: 1987-08-31
Granted: 1996-02-16
Abstract: Improved significant sample detection for a pitch detector for use with speech analysis and synthesis methods by performing a reverse order search and a forward order search of digitized speech samples. A reverse search detector (12) is responsive to segmented digital samples for determining a set of candidate samples by initially selecting one of the digitized samples as a present candidate sample and comparing in reverse order each of the digitized samples with the present candidate sample until a digitized sample is found whose amplitude is greater than the present candidate sample or the compared sample is greater than a predefined number of samples from the present candidate sample. When either of the previous conditions occurs, the compared digital sample becomes the new present candidate sample and the reverse search continues. During the reverse search, each of the compared samples that has not replaced the present candidate sample is set equal to zero. After the reverse search has been performed and a set of candidate samples has been determined, a forward search detector (14) then initially determines a present significant sample. The latter detector compares this significant sample with each of the candidate samples until a candidate sample is found whose amplitude is greater than the present significant sample or the compared candidate sample is more than a predefined number of samples away from the present significant sample. When either of those conditions occurs, the forward search detector saves the value of the amplitude and location of the candidate sample and replaces the present significant sample with that candidate sample and continues the search. A single forward and reverse search determines all of the significant samples.

Title: Method of injection moulding and moldings produced thereby
Inventor: YAMAZAKI KUNIO
IPC: B29L22/00
Filed: 1988-04-27
Granted: 1995-10-23
Abstract: A resin moulding is produced by introducing molten synthetic thermoplastic resin (19) into a mould cavity (13), sufficient to fill completely the mould cavity. Subsequently, during the cooling of the resin, pressurised gas is introduced into the resin within the mould cavity. The resin moulding cools and hardens in the mould cavity whilst the gas is maintained under pressure. The mould cavity is designed to manufacture mouldings with unevenly distributed thick walled sections (3) connected to at least one gate (4;44) for the introduction of the pressurised gas, which flows only within the resin forming the thick walled sections and immediately adjacent areas of the moulding thereby taking up the shrinkage in the resin.

Abstract: A dual bus microcomputer system including a cache subsystem improves performance under certain circumstances by allowing programmable control over the LOCK function. More particularly, additional logic is coupled between the LOCK output of the CPU and the LOCK input of the cache controller. A control bit from an I/O port is a second input to the additional logic. With the control bit in one state, the logic allows the LOCK input to follow the LOCK output. In the other state of the control bit, the LOCK input is disabled regardless of the state of the LOCK output.
