Title: Type a platelet-derived growth factor receptor gene
Inventor: MATSUI TOSHIMITSU
IPC: A61K51/10
Filed: 1990-02-08
Abstract: Discoveries are disclosed that show particular aspects of recombinant DNA  technology can be used successfully to pro-duce a hitherto unknown type of human Platelet-Derived Growth Factor (PDGF) receptor protein (see genetic map, figure 2) free of other PDGF receptors. These proteins can be produced from DNA segments in cells in various functional forms. These forms variously enable biochemical and functional studies of these novel receptors as well as production of antibodies. Means are de-scribed for determining the level of expression of genes for specific types of PDGF receptor proteins, for example, by measuring mRNA in cell with PDGF receptor type-specific DNA probes or by measuring antigene in biological samples with type-specific antibodies.

Filed: 1991-07-05
Abstract: ABSTRACT OF THE DISCLOSURE    A support beam supports a box type beam on which there is located, essentially tangentially to the shell surface of a guide roll coordinated with it, a contact surface for the adhesive tape.  Perpendicular to the contact surface, a holding slot for the adhesive tape is provided on the box-shaped beam.          The adhesive tape protrudes out of this holding slot with a considerable part, of which the cover foil is removed.  A blowing device or blowing channels with blowing orifices bend the part of the adhesive tape protruding out of the slot upward so that, with the support beam approaching the guide roll, this part of the adhesive tape practically is in contact with the contact surface.  In this way, the adhesive tape can be fastened on the web end wrapping around the guide roll.

Title: Digital signal encoder
Inventor: AKAGIRI KENZO
IPC: G10L19/035
Filed: 1991-08-23
Abstract: An apparatus for encoding an input digital signal divides the input digital signal to produce frequency components of increasing bandwidth as the frequency increases, performs blocking on each of the frequency components to produce blocks of decreasing time length as the frequency increases, performs a fast Fourier transformation on each block and quantizes each block using a quantization characteristic set in accordance with a comparison of the energy of each frequency component in each block with a masking spectrum. The masking spectrum includes both a masking effect on the frequency base of the input signal and masking effect on the time base of the input signal and may further include effects of the minimum audible curve of the human hearing sense characteristic. Utilization of both the temporal and frequency masking effects permits reduction in the bit rate of the encoded signal using real time processing and without deterioration in sound quality.
