Title: Oil feeder and oil feeding method
Inventor: IKEDA KIMIO
IPC: B23Q11/10
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To improve machining performance by using an oil feeder for a machining part of a machine for machining such as cutting, grinding and polishing. SOLUTION: An oil feeder 1 is provided with a spray nozzle 2 for jet-feeding oil, an electromagnetic pump 3 for intermittently feeding oil to the spray nozzle 2, an oil tank 4 for storing oil to be fed to the electromagnetic pump 3, an air compressor 5 for supplying high pressure air to the spray nozzle 2, and an air regulator 6 for adjusting the pressure of high pressure air. In this oil feeding method, a mixture of high pressure air and oil particulates, or only high pressure air is alternately spray-fed or jet-fed. With oil thus intermittently spray-fed to a machining place, temperature rise is suppressed by the formation of a thin film (oil film), so that efficient machining can be performed stably at the normal temperature or lower, and cutting resistance is lowered so as to increase machining speed by a large margin and thereby to improve machining efficiency.

CONSTITUTION:Molecules 2... of a dichroic dyestuff having anisotropy in absorbing a light beam in the major axis direction 21 and the minor axis direction 210 of the molecule are arrayed in some prescribed direction and fixed in a transparent medium 3. In this state, an incident light A1 being parallel to the thickness direction of this optical control panel 1 becomes a transparent (colorless) transmission light A2, and an incident light B1 in the (oblique or vertical) direction which intersects with the thickness direction becomes a colored transmission light B2.

Title: Ac output current abnormality detector
Inventor: HIDA MASAYUKI
IPC: H02M7/48
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To operate or protectively stop a converter without damaging a self- extinguishing type element by detecting a one-polarity DC current when it is outputted on the AC output side of a self-excited converter. SOLUTION: An AC output current of a power converter is detected by a current-detecting means 2, and integrated by an integrating circuit 3. The integrated result is compared with a positive set value and a negative set value by a comparing circuit 5. When the integrated result exceeds the positive or negative set value, it is discriminated that the AC output current of the power converter is biased to a single polarity, thereby detecting abnormality of the AC output current. When the AC output current of a self-excited converter outputs a single-polarity DC current, it can be prevented that operation is continued, the duty factor of one side self-extinguishing type element becomes high, generated loss increases, and the element is damaged.
