IPC: A23L29/00
Filed: 1997-02-26
Abstract: The invention concerns bacteria having byle salt hydrolysis activity  and  optionally  and  preferably  also  bile  salt polymerisation  activity.   Food  products  comprising  such bacteria have been found to be capable to reduce the blood cholesterol level in the human blood. The  effect is obtained by  interference  with  the    cholesterol  and/or  bile  salt metabolism and   is based on BSH activity of the bacteria. Food products which,  on  the  basis  of  their normal  daily intake  provide  a  daily-BSH-intake  of  0.3  micro-mol/min/kg bodyweight, are preferred, and even more preferred are food products  providing at least a daily-BSH-intake of 0.6 micro-mol/min/kg bodyweight.  In a further preferred embodiment a BSH  activity  of  at  least  0.8  micro-mol/min/1e10  cfu  is obtained  by  the  common,  daily  intake  of  food  products comprising the bacteria. Further preferred are food products comprising fat,  wherein at least 40% of the fat are poly unsaturated fatty acids.

Title: Electric power steering device
Inventor: KODAIRA TADAO
IPC: B62D5/04
Filed: 1997-06-24
Abstract: In an electric power steering device comprising a yoke made of a tubular member and carrying permanent magnets, and a hollow motor shaft coaxially and rotatably received in the yoke to carry a motor armature which cooperates with the permanent magnets to form an electric motor for the power steering device, a section of the yoke extending from an axial end thereof to a part thereof surrounding an axial end of the motor shaft defines an inner diameter which is greater than an outer diameter of the nut member so that the output torque of the electric motor can be measured during the course of assembling the power steering device by allowing a testing tool to be inserted from the open end of the yoke without any interference and to be applied to an suitable part of the nut member or the motor shaft. Thus, the performance of the electric motor can be directly evaluated before the power steering device is fully assembled so that any faulty electric motor can be either rejected or repaired before any further assembling work is conducted.
