IPC: A23L5/10
Filed: 1992-04-16
Abstract: PURPOSE:To concentrate a high-viscosity food such as a sweet potato in a short time. CONSTITUTION:A high-viscosity food is placed in a hermetically sealed heating vessel 1 and forced ventilation of hot air into the heating vessel 1 with a heated air feeder 29 and decompression of the interior in the heating vessel l with a vacuum pump 30 are alternately repeated many times at an interval of several min while heating the food with pressurized steam from the outside of the heating vessel 1 and stirring the food with inner and outer blades 13 and 14. The volume of the food and evaporation area of water are increased by decompression in the heating vessel 1 and the hot air is applied to the food which is being stirred. Thereby, the water can efficiently be evaporated from the food. Since the interior of the heating vessel 1 is changed into the decompression and atmospheric pressure many times at an interval of several min, the food rapidly repeats the volume change to promote the liberation of bound water.

Title: Exciting circuit for step motor
Inventor: ICHINOSE ATSUNORI
IPC: H02P8/32
Filed: 1984-05-15
Abstract: PURPOSE:To reduce a deviation of positioning position due to the displacing direction of a head by varying a current ratio flowed to two excited phases. CONSTITUTION:An exciting phase is switched while a transistor 14 remains ON from a transistor 11 when displacing in counterclockwise direction. Thus, a deviation of beta exists from the displacing O line. In case of clockwise displacement, a transistor 11 of leading direction (phase A) is turned OFF from the stopping position, and a phase current is flowed through a variable resistor 15. At this time, the transistor 12 of the phase B is turned ON. Thus, the stopping position when displaced in the clockwise direction has a deviation of alpha from the displacing O line. A deviation due to the displacing direction difference of alpha and beta can be almost suppressed to 0 by optimally selecting the value of a variable resistor.
