Abstract: PURPOSE:To prevent a frame step-out of the same degree or lower degree group device following a switching system in a switch mode between the using and spare circuits, by using a high-speed switching active element to a switching circuit and at the same time delivering an alarm when the phase difference between input signals exceeds a fixed range. CONSTITUTION:A high-speed switching active element is used to a high-speed switching circuit 18. This eliminates the need to obtain the coincidence between the polarities of signals of two systems which are supplied to the circuit 18. In this case, however, the phases of both signals must be coincident with each other within a fixed range. In this respect, variable delay circuits 13 and 13' are provided. The outputs of both circuits 13 and 13' are applied to the circuit 18 as well as to both wave rectifying circuits 14 ans 14'. The both-wave rectified signal is applied to a phase comparator 15, and the phase difference is detected between bipolar signals of both systems. The phase difference is converted into a voltage signal by an integration circuit 16 and applied to a phase difference deciding circuit 17. The circuit 17 produces an alarm signal when said voltage signal exceeds the threshold voltage set previously to warn that the control is required to circuits 13 and 13'.

Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To provide an optical device which has simple structure with torque limiter function, and following manual operation means to make quickly move movement of automatic operation means. SOLUTION: An operation ring 35 is combined with an outputting cylinder 43 of an ultrasonic motor using the magnetic force combining means 51. The magnetic force combining means 51 fixes a first magnet plate 52 to the outputting cylinder 43, and a yoke plate 54 to the operation ring 35. A second magnetic plate 56 is installed between the first magnetic plate 52 and the yoke plate 54, spacers 57, 58 are secured on both sides of the second magnet plate 56.

IPC: H02K1/27
Filed: 1988-02-17
Abstract: PURPOSE:To rotate a permanent magnet rotor at a high speed by engaging a thin cylindrical sleeve made of ceramics with the outer periphery of a permanent magnet. CONSTITUTION:A permanent magnet 12 is adhered with an adhesive 13 onto the outer periphery of a yoke (made of iron steel) 11.

IPC: B29C43/00
Filed: 1980-03-15
Abstract: PURPOSE:To avoid the internal irregularity of a composition by a method wherein the changing speed of a distance between hot plates is detected to effect the heating control of the hot plate by the detected value in case the formed body is hot-pressed between a pair of hot plates. CONSTITUTION:In case a laminated body Z wherein a plurality of prepregs 2 are laminated is hot-pressed between a pair of hot plates 1, the changing speed of the distance between the hot plates 1 shows the temperatue difference between the inner and outer sides of the laminated body 2. When the changing speed is small, the temperature difference between the outer and inner sides is small, on the other hand, when the changing speed is high, the temperature difference between the outer and inner sides is large. Utilizing the above-described nature, a differential transformer 5 detects the distance between the hot plates 1 and changes it into an electric signal while this signal is changed into the changing speed by a hot plate distance changing speed computer 6 to effect the control of heating of the hot plates 1 by this value. According to this method, a form having no internal irregularity in the composition thereof may be obtained.

Title: Preservation and regeneration of living organism organ and system therefor
Inventor: SEKI KYOKO
IPC: A01N1/02
Filed: 1992-02-20
Abstract: PURPOSE:To provide a preservation and regeneration system capable of rapid freezing, rapid thawing of living organism organs with large heat capacity, causing no organ lesions. CONSTITUTION:Taking advantage of the blood vessels in an organ, these vessels are perfused with a cold liquid/hot liquid, thereby accomplishing uniform freezing/thawing of the entire organ. In freezing, an organ is first precooled to low temperatures under perfusion of the organ with a freeze damage preventive (e.g. glycerin solution, dimethylsulfoxide). Thence, the organ is frozen; however, when a cooling liquid with low evaporation temperature such as liquid nitrogen is used, it evaporates and rapidly expands in the vessels, leading to possible damage thereof; therefore, the entire organ is rapidly frozen using several kinds of cooling liquids differing in evaporation temperature from one another to ensure perfusion in a liquid state at all times. On the other hand, in thawing, the vessels are perfused with a large quantity of a hot liquid with its temperature kept high to effectively raise the temperature of the organ as a whole, thus accomplishing rapid thawing of the organ.

Abstract: PROBLEM TO BE SOLVED: To enable an examiner to concentrate his/her efforts on a measurement work, and eliminate the occurrence of a difference in judgement depending on the examiner regarding the finish of measuring works for improving the accuracy of measurement results by making judgement as to whether the measurement results satisfy the preset finish condition, and informing the examiner accordingly when the condition is satisfied. SOLUTION: When the prescribed number of measurement values except a measurement error is obtained by an ocular refractometer, a control part 70 judges that a measurement finish condition is complete and ends an auto-shot measurement process. Also, a message 'FINISH' is shown on a TV monitor 6, meaning that the measurement of one eye is finished. After the measurement of one eye is complete, the other eye is similarly measured. When the measurement values of both right and left eyes satisfy the prescribed measurement finish condition for measuring cornea curvature and eye refractive power, the control part 70 finishes the measurement and outputs measurement data to a printer 95.
