Title: Coffee mill
Inventor: FUKUDA TAKAYUMI
IPC: A47J42/26
Filed: 1987-09-30
Abstract: PURPOSE: To automatically crush coffee beans into optimum grain size by controlling the stop of a motor by providing a piezoelectric element for detecting the rotational vibration of the motor and a detection circuit for detecting crushed state of coffee beams from the output of this piezoelectric element. CONSTITUTION: The piezoelectric element 1 is attached near a motor 4, and the rotational vibrations of the motor 4 are detected. The detection circuit 2 receives the output of the element 1 and detects a waveform (e) at a point C before the end of coffee bean milling. Besides, a waveform (f) is detected at the point C after the end of coffee bean milling. The waveforms detected at this point C are stored in a control circuit 3 and when the waveform (f) after the end of milling of coffee beans is detected, the motor 4 is stopped. Thus, the coffee beans can be automatically crushed into optimum grain size.

Title: Oil level detector for compressor
Inventor: MICHIHASHI HIROSHI
IPC: F25B1/00
Filed: 1997-09-11
Abstract: PROBLEM TO BE SOLVED: To detect an oil level accurately by matching the height of an oil conduction pipe with the height of the working point of an oil level detecting means in an oil level detector. SOLUTION: A float type oil level detector 11 coupled with an oil separator 10 is provided with a pressure equalizing conduction pipe 1 and an oil moving conduction pipe 9 wherein the height of the oil conduction pipe 9 is matched with the height of working point A of a float switch in the oil level detector 11. Even if the oil level in the oil separator 10 is different from that in the oil level detector 11, they are conducted through a gas-liquid two phase in the conduction pipe 9 in the vicinity of the working point A. Consequently, the oil moves from a high oil level toward a low oil level and the oil levels are eventually matched thus ensuring accurate operation at the working point A. This system is applicable to a case for detecting and controlling the liquid level in an L tank, or the like.

Abstract: PURPOSE:To improve a yield of products by quantifying friction of rolls by means of a load curve of Abbot and determining a management reference value of the rolls. CONSTITUTION:A plurality of rolls from new rolls to rolls with large friction having different surface conditions are classified by degrees of friction, while a roll surface fine shape on each stage is detected by a load curve of Abbot and degrees of friction are quantified to determine roll management criteria. The load curve of Abbot is represented by a curve wherein a horizontal axis is ratio tp of a total sum of a real body part cut by a line which passes through an optional depth DH from a peak of a waveform 10 and is parallel to a center line (average line) and a measurement length lm. H refers to difference in height between the highest point and the lowest point in an entire measurement length lm in the waveform 10. By using such criteria for managing the rolls, friction conditions of the rolls can be captured so that appropriate roll replacement is possible, thereby improving a yield of products.
