Title: Rotation discriminating device for rotary body
Inventor: TANAKA YASUSHI
IPC: G01P3/42
Filed: 1985-10-03
Abstract: PURPOSE:To securely decide the rotational speed of a rotary body even if a reference signal for rotation decision making is interrupted by detecting at least two kinds of signals having periods corresponding to the rotational speed of the rotary body. CONSTITUTION:A signal passage limiting circuit 8 inhibits an ignition signal S4 from being passed for a specific time T after the reference signal S1 is inputted. This signal S1 when outputted normally and continuously or the signal S4 when the specific time T is elapsed after the signal S1 is interrupted is used as a signal for detecting the abnormality of the rotation of an engine. Further, the specific time T is shorter than the period wherein an inhibiting signal is outputted by an engine rotation decrease deciding circuit 3 and longer than the reference signal period of the lowest rotational speed at which engine rotations can be maintained. Thus, the signal S1 or S4 is inputted to a period arithmetic circuit 2 through an OR circuit 9 to calculate the period, which is then decided by the circuit 3; when the period is longer than a specific reference value, the inhibiting signal is outputted to inhibit data in a storage circuit from being updated.

IPC: C12N1/14
Filed: 1987-09-02
Abstract: PURPOSE:To obtain porous and spongy water-resistant bran pellets not readily collapsing in shape, having improved permeability and water retention characteristics, by drying bran alone or blending bran with starch, rain flour and water, forming and drying and steaming the dried formed blend. CONSTITUTION:Bran having proper particle size is blended with water or water and small amounts of starch and one or more grain flour selected from corn starch and wheat flour as a binder and formed.
