Patent JP-H04371115-A (JP)
Title: Electric pot
Inventor: TAKACHI HIROSHI
IPC: A47J27/21
Filed: 1991-06-20
Abstract: PURPOSE:To make water-boiling possible even when a power source is turned on immediately after hot water is poured into a receiving vessel. CONSTITUTION:An empty boiling detecting means 17 is composed of a temperature gradient detecting means 23 and a judging means 24. The temperature gradient detecting means 23 reads in the output of a hot water temperature thermistor 7 on the output of a timer means 22 every fixed time after 20 seconds from the resetting of a power source executed by a power source reset detecting means 26 for computing the temperature rise of a receiving vessel 2. The judging means 24 controls a heater 4 and a power source voltage breaking means 28 on the outputs of the hot water temperature thermistor 7 and of the temperature gradient detecting means 23. Thus, since the detection of empty boiling is first executed after 20 seconds from the turning on of the power source, the empty boiling detecting means 17 can certainly detect that hot water has been poured in the receiving vessel 2.

Title: Optical isolator
Inventor: ISU TOSHIRO
IPC: G02B27/28
Filed: 1984-07-16
Abstract: PURPOSE:To obtain a small-sized optical isolator by forming a magnetic material thin film having a strong coersive force on the surface of a waveguide of a thin film isolator. CONSTITUTION:A ferromagnetic material thin film 10 is formed on mode selectors 7a and 7b and a mode converter 9 between them. The light incident from a prism 6a becomes light of the TE mode by the selector 7a and goes in the waveguide of a Farady rotator 3 consisting of a thin film. In this case, the light is subjected to Farady rotation and has the plane of polarization rotated if magnetization of the thin film 3 is saturated. Its length is so set that 45 deg. Farady rotation is generated. Thereafter, the light is converted to light of the TE mode by the converter 9 and is transmitted through the selector 7b and a prism 6b. Meanwhile, the light in the reverse direction is excluded by the selector 7a in accordance with the reciprocity of Farady rotation. Magnetization of the rotator 3 consisting of the thin film is saturated for the purpose of operating this optical isolator.

Abstract: PURPOSE:To obtain a high recording density by branching the top end of a probe to cross-shaped three directions, and allowing a recording medium to have the line-and-space pattern of a specific width and depth. CONSTITUTION:A fine vibration in a three dimensional direction, that is, the fine vibration in x, y, and z axial directions, that is, the vibration of a probe 10 by an amplitude less than 1nm in the x, y, and z-axial directions, is imparted at every one time of scanning of the probe, and the rate of change of tunnel currents at this time is measured, so that the position where the tunnel currents are running between the probe 10 and a sample can be recognized.

IPC: G06V10/147
Filed: 1993-06-21
Abstract: PURPOSE:To improve reliability and to shorten processing time by displaying the group of candidate corresponding points on the straight line representing the group of the candidate corresponding points after the group thereof is obtained. CONSTITUTION:The corresponding point on another image corresponding to a plurality of points on an epi-polar line, which is extracted from one arbitrary image out of a plurality of images, are extracted. At this time, after the group of candidate corresponding points is obtained, the straight line representing the obtained group of the candidate corresponding points is obtained, and the group of the candidate corresponding points is moved to the straight line. Namely, the right epi-polar line LeRj, where the corresponding points should be intrinsically obtained, is obtained by computation. The candidate corresponding point PRj, which is obtained on the right-side image by a conventional corresponding-point extracting method, is moved to a point PRi' at the shortest distance on the obtained right epi-polar line LeRj. Thus, the corresponding relation between a plurality of images is accurately obtained in comparison with a template matching method. Therefore, the corresponding relation at the accuracy of sub-image can be obtained, and the reliability is improved.

Title: Dc motor
Inventor: KAWAKUBO HIROKI
IPC: H02K23/40
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To easily reduce the size of a DC motor and improve the output of the motor by forming the outer core of a revolving armature of the motor in such a way that the axial length of the core becomes longer than that of the inner core of the armature and the tooth sections of the core become thicker in wall thickness, and then, the sections corresponding to slots become thinner in wall thickness. SOLUTION: Since the permanent magnets 28 of a DC motor are elongated in the axial direction of the motor, the magnetic fluxes from the magnets 28 increase, but the magnetic fluxes interlinked with a coil 10 are increased by taking the magnetic fluxes form the magnets 28 in the outer core 23 of a revolving armature 6 which has nearly the same length as those of the magnets 28 in the axial direction and, at the same time, squeezing the magnetic fluxes to the inner core 22 of the armature 6 by means of the thick-wall section of the outer core 23. Consequently, the output of the motor is increased without increasing the size of the motor. In addition, the slots of the rotor core 22 are not opened, because the outer core 23 has a cylindrical shape. Therefore, the rotational accuracy of the DC motor is improved, because the permeance variation of a magnetic circuit is relieved and cogging torque is reduced.
