Title: Method for preparing boron nitride
Inventor: HIRANO SHIN-ICHI
IPC: C01B21/064
Filed: 1984-12-05
Granted: 1989-07-20
Abstract: There is disclosed a method for preparing boron nitride comprising pyrolyzing at least one compound selected from the group consisting of borazine and/or a borazine derivative at a temperature of 150 to 700 DEG C and a pressure of 10 MPa or more. The boron nitride manufacturing method of this invention makes possible to manufacture amorphous boron nitride in which the conversion rate into cubic boron nitride is high, since the activation energy of the conversion reaction into cubic boron nitride is very small.
Patent DE-3484447-D1 (DE)

IPC: H04B1/66

Granted: 1991-05-23
Abstract: Apparatus and a method are disclosed for digitizing a voice signal as it occurs and the digitized signal is compressed and stored for subsequent reconversion to a voice signal at a latter time. Binary words derived from digitizing the signal in an analog-to-digital converter represent the voice non lineary and are first linearized by a first processor and then stored in a first memory until a block of binary words are assembled. Next the block of binary words are transferred to a second buffer memory and a second processor compresses it using time domain harmonic scaling processing which extracts the pitch of the original voice and also compresses the voice frequency spectrum to affect a 2:1 reduction in the number of stored binary words representing the digitized voice signal. This reduced amout of data is then upsampled by a factor of four using linear interpolation to derive a pseudo higher sample rate required for further processing using continuously variable slope delta modulation processing which yields one binary bit out for every binary word processed. The resultant bits are assembled into eight bit words and then stored in a third memory. Another binary word representing the pitch is added and the result is a 4:1 compression of the original digitized data. The compressed digitized data is stored in a bulk memory. Thereafter, more digitized samples of the voice signal undergo this same processing. Compressed digitized voice signals may be reconverted to a voice signal for playback by processing the digitized and compressed voice signals generally in the reverse order. Playback speed control may also be accomplished without changing the pitch of the voice. To double the playback speed the time domain harmonic scaling processing is deleted in playback, thus leaving the frequency spectrum compressed and a 2:1 reduction in binary words representing the digitized voice. To slow the playback speed the digitized voice signals undergo modified TDHS processing.

Abstract: A method of encoding time encoded data in which a stream of time encoded symbols representing the data is divided into a number of successive time frames. The repetition frequency of each symbol in each time frame is determined and a precursor code, indicative of the symbols according to their repetition frequency, is derived for each time frame. A linear or non linear code, or any combination thereof, is assigned to the symbols in accordance with the precursor codes to produce a code series for each time frame. The precursor codes and code series for the time frames are then combined thereby to achieve a reduction in the bit rate of the digital data stream representing the data. The combined precursor codes and code series may be stored before or after transmission.

Title: Sunshade device
Inventor: RIEHL HORST
IPC: E04F10/00
Filed: 1986-03-06
Granted: 1989-02-09
Abstract: A signal generator equipped with a shading device and two light sensors is arranged on the upper side of a slat equipped with retro-reflective prisms and rotatable about a longitudinal axis. Depending upon the sun's position relative to the slat, the light sensors are variously shaded or illuminated by means of the shading device, and when the slat is rotated about its longitudinal axis, the light sensors supply electrical code values which change in opposing directions. A difference between the code values is fed via an amplifier to a servo-motor which rotates the slat about its longitudinal axis until the plane of incidence of the sun's rays, which passes through the longitudinal axis, is at right angles to the upper side of the slat. This ensures that sun's rays which hit the slat are reflected regardless of the sun's position, the time of year, and the alignment of the facade plane in which the slat is arranged.
