Title: Vocal display device
Inventor: TSUMURA MOHOJI
IPC: G10L11/00
Filed: 1992-01-16
Abstract: Conventional karaoke devices simply show lyrics on screen.         This invention displays not only lyrics but also data useful for the enhancement of the singer's presentation such as the strength of the vocals and the pitch.  More precisely, vocal data, which indicates the special requisites of a specific vocal rendition such as its strength and pitch, and the current lyric position indicator, which marks the current position in the lyrics, are correlated with the music data to which they correspond and then stored in memory.  The said vocal data and current lyric position data are then read out of memory and each block of vocal data is displayed on the screen of a visual display medium a little in advance of the music to which it corresponds while the current lyric position within said block of vocal data is indicated in time with the music.  Moreover, the strength and basic frequency of an actual vocal rendition can be detected and compared with the stored vocal data.

Inventor: OGAWA KAZUFUMI
IPC: C09D4/00
Filed: 1992-01-29
Abstract: ABSTRACT       Disclosed  is  an ornament with a thin film formed on the ornament surface.  The thin film includes a fluorocarbon-based  adsorbed  monomolecular  film,  and  the  thin  film  is covalently bonded to the ornament.  By contacting the ornament with the non-aqueous solution containing a chlorosilane group at  one  end  and  a  fluorocarbon  chain  at the  other  end,  a reaction  occurs  between  hydroxyl  groups  at  the  ornament surface and the chlorosilyl groups of the material having a plurality of chlorosilyl groups.   A monomolecular  film which is  covalently  bonded  to  the  ornament  surface  is  thereby obtained.   A  thin,  fluorine-containing,  monomolecular  film thus can be formed on the ornament such that it is chemically bonded to the ornament.  The film is anti-contaminating, water-and oil-repelling, durable and does not spoil the intrinsic luster of the ornament.

Title: Elevator cab guidance assembly
Inventor: TRAKTOVENKO BORIS G
IPC: B66B1/06
Filed: 1992-07-30
Abstract: Abstract An elevator cab assembly is provided with a rail guidance system which provides a substantially vibration-free ride despite uneven passenger loading.  The guidance system includes side-to-side and front-to-back rail guide rollers which are adjustably mounted on the cab frame. The rail guide rollers are pivotally mounted on links which are  spring-biased toward the guide rail blades. Stops are provided on the links to limit the extent of permissible pivotal movement of the rollers away from the guide rail blades.   Actuators are connected to the link springs to selectively increase the spring pressure act-ing on the links when the pivot stops are engaged as a result of uneven passenger loading in the cab.  The actu-ators ensure that the roller links do not ride against the stops,  thereby ensuring a continuous spring biased engagement between the guide rollers and the guide rail blades, and a substantially vibration-free ride.

Filed: 1992-09-02
Abstract: A DNA sequence encoding a potato leafroll virus coat protein having at least one internal translation initiation codon in a different reading frame than the native PLRV coat protein DNA sequence altered to a non-initiator codon is provided. Two translation initiation sites at the start of a 17kd open reading frame in a different reading frame than the native PLRV coat protein DNA sequence are preferably altered. A stronger stop codon is also provided in the modified PLRV DNA sequence. The modified DNA sequence having the internal translation initiation codons at the start of the 17kd open reading frame altered to non-initiator codons can be used in a gene to transform plants of the Solanaceae family to obtain transgenic plants resistant to PLRV. A synthetic modified potato leafroll virus DNA sequence is also provided which has the changes in the translation initiation sites and is further made to be more "plant-like". Multiple copies of the modified or synthetic modified PLRV coat protein DNA sequence driven by different promoters have also been transformed into potato with advantageous results. The modified potato leafroll virus DNA sequences of this invention are particularly useful in obtaining transgenic potato plants resistant to infection by potato leafroll virus.

To produce an engine block, one or more solid salt cores are positioned within a metal mold with the space between the cores and the mold defining a die cavity.  A molten hypereutectic aluminum-silicon alloy containing more than 12% silicon is fed into the die cavity and on solidification of the molten alloy, precipitated silicon crystals are formed, which are distributed throughout the wall thickness of the cast part and also on the surface bordering the salt cores which constitute the cylinder bores in the cast block.  The salt cores are subsequently removed from the cast block by contact with a solvent such as water.

Abstract: ABSTRACT      Owing to the limited land available, environmental issues and the high costs of current funerary arrangements the enclosed prospectus intends to initiate a more efficient use of space at a much reduced cost.      The intention of this concept is to have smaller parcels of land, 16" X 12", the size of our earthstones, arranged in such a way as to create a lightly packed, asethetically, pleasing, alternative.  The flat earthstone wil eliminate maintainance altogether.  The density of arrangement will permit current graveyards to be more efficient and will allow graveyards already considered full, to be reopened, as this method would encourage the relocation of existing "WANTED SPACE" (ie. roadways) to be developed using this proposal.      The VaulteCh compound will be marketed as a permanently sealed container, as the products involved will have a life expectancy of thousands of years.
