Title: Voice detection apparatus
IPC: G10L25/00
Filed: 1990-04-09
Abstract: A voice detection apparatus comprises a signal 
power calculation part (11) for calculating a signal 
power of an input voice signal for each frame of the 
input voice signal, a zero crossing counting part (12) 
for counting a number of polarity inversions of the 
input voice signal for each frame of the input voice 
signal, an adaptive prediction filter part (14) for 
obtaining a prediction error signal of the input voice 
signal based on the input voice signal, an error signal 
power calculation part (15) for calculating a signal 
power of the prediction error signal which is received 
from the adaptive prediction filter part, a power 
comparing part (16) for comparing the signal powers of 
the input voice signal and the prediction error signal 
and for obtaining a power ratio between the two signal 
powers, and a discriminating part (13) for 
discriminating voiced and silent intervals of the input 
voice signal based on the signal power calculated in the 
signal power calculation part, the number of polarity 
inversions counted in the zero crossing counting part 
and the power ratio obtained in the power comparing 
part. The discriminating part discriminates the voiced 
and silent intervals of the input voice signal based on 
the number of polarity inversions. On the other hand, 
the discriminating part compares an absolute value of a 
difference of power ratios between frames with a first 
threshold value and discriminates whether a present 
frame is a voiced interval or a silent interval 
depending on whether a previous frame is a voiced 
interval or a silent interval when the signal power of 
the input voice signal is less than a second threshold 
value.

Title: Semiconductor laser device
IPC: H01S5/343
Filed: 1990-06-12
Abstract: Disclosed herein is a semiconductor laser device 
of the field modulation type having a structure in which 
the threshold carrier density for laser oscillation is 
reduced so as to enable an effective action of a modulated 
electric field applied externally on an active region for 
radiating light, thereby enabling an extremely high speed 
modulation. A quantum structure which does not fulfill 
the charge neutrality condition for free-carriers or a 
strained super lattice structure is adopted as the 
structure in which the threshold carrier density is 
reduced.

Title: Rotation of a document through a finite angle
IPC: B65H9/00
Filed: 1992-05-07
Abstract: Sheets (39), such as business forms, are turned so 
that their orientation is changed from landscape to protrait 
mode, or vice versa. Simple apparatus effects sheet 
rotation, and includes a conveyance surface (15) on which a

Patent EP-0576389-A3 (EP)
IPC: C05F7/00
Filed: 1993-06-22
Abstract: The hitherto conventional standard method of direct field application of liquid manure and slurry is burdened with a number of disadvantages such as primarily environmental pollution in the form of odour emissions, giving off ammonia gas and nitrate seepage, as well as high capital expense for the storage and application technology. In the case of domestic sewage (effluents), collection in central sewage treatment plants causes high costs with unsolved disposal problems for the residues. The novel composting process according to the invention is intended to overcome these disadvantages and to be an economically profitable alternative. Slurry, liquid manure and sewage are pumped from a collection pit or vessel (1.0 in the figure) into a fermentation and drying tower (2.0), directly after their production and are discharged centrally above the transport pallet (2.2) filled with wheat straw. The thin slurry dripping off with evaporation of water and leaving behind coarse components is withdrawn via a drain (3.1), incorporated in the floor, into the filtrate vessel (3.0). From there, it is forced via a suction and pressure pump (3.3) to a spray nozzle in the upper tower part (2.3). The spray drops descending in the ascending air stream release water, moisten the compost pallet with their residual water content and return as excess into the filtrate circulation. The ascending air stream escapes (2.4) at the roof via a demisting orifice. The air intake for oxygen supply and drying proceeds from a solar warm air collector (4.0). The result is a compost which is further dried in the tower to below 30% residual water content for loss-free storage. The process is suitable for all animal husbandry businesses and households in an isolated situation instead of conventional disposal methods; because of its low capital expenditure, it is especially suitable also for small-scale businesses. <IMAGE>

Title: Protein expression system.
Inventor: SPANA CARL
IPC: C07K14/705
Filed: 1994-09-30
Abstract: An expression system for producing and isolating large quantities of protein. This system employs an expression vector, comprising (a) a coding region for a glutathione-binding polypeptide (glutathione-s-transferase preferred), operatively connected to a promoter, (b) a second coding region in-frame with the first coding region, and (c) at least one restriction site between the first and second coding regions wherein a fusion protein of the first and second coding regions will result from expression of the vector. This vector is used in a host cell, which in turn is used in a process for isolating and purifying a protein. This process comprises (a) treating the host cell under conditions allowing expression of the vector, whereby a fusion protein of the first and second coding regions will be expressed; (b) exposing proteins from the host cell to glutathione resin, whereby the fusion protein will adhere to the resin; and (c) cleaving the expression product of the second coding region from the resin. Also described is a process for expressing a nucleic acid sequence, which comprises (a) inserting the nucleic acid sequence into a baculovirus expression vector in-frame with the first coding region; (b) placing the vector into a host cell; (c) treating the host cell under conditions allowing expression of the vector, resulting in expression of a fusion protein of the first coding region and the sequence inserted in step (a); (d) exposing proteins from the host cell to glutathione resin, whereby the fusion protein will adhere to the resin; and (e) treating the adhered fusion protein with a protease to release the expression product of the nucleic acid sequence from the resin. A baculovirus/Spodoptera frugiperda expression system is preferred. <IMAGE>

Title: Guide system and method for controlling the lateral inclination of a railway vehicle.
Inventor: JOOS UWE DIPL-ING
IPC: B61F5/22
Filed: 1994-12-05
Abstract: If the lateral acceleration conditions are measured on a rail vehicle and if the inclination of a load floor is correspondingly optimised, problems occur as a result of time delays between the measurement and positioning and as a result of faults which are included in the measurement. This is overcome in that track data which are relevant to the lateral inclination are stored in a track model memory (27), with the detected actual position (1), the track data which are just relevant or will be relevant in future are called up and the inclination ( alpha s) of the load floor which is necessary at that precise moment is calculated (29) and set (11) as a function of the identified instantaneous speed (9) of the vehicle. <IMAGE>
