Abstract: PURPOSE: To diagnose unbalance positions in a rotor to make rotation of the rotor smooth, by extracting unbalance vibration components, which are synchronized with the number of rotations, from the vibration signal of the rotor of a rotary machine such as a turbine and by utilizing the obtained composite vibration vector.  
     CONSTITUTION: When the number of rotations of rotor 1 obtained by tachometer 4 is equal to the number of rotations determined previously, vibration signals of bearings 2 and 3 detected by vibration detector 5 are supplied to vibration analyzer 7. In this analyzer 7, unbalance vibration components are analyzed on a basis of the phase reference signal obtained from tachometer 4 and the vibration signals above according to high-speed Fourier analysis, etc. Next, vibration vectors of all of the number of rotations for diagnosis for vibrations of bearings 2 and 3 analyzed in this manner are synthesized by vector operator 8, and the amplitude and the phase of vibration in respective numbers of rotations for diagnosis are compared by comparator 9. The relation between unbalance positions and vibration is stored in memory 10 previously, and unbalance distribution is decided on a basis of the result of comparator 9 by pattern recognition equipment 11, thereby diagnosing unbalance positions of rotor 1 simply.

IPC: G03G15/00
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To enhance the operability of a sorting device and to prevent miscopying from being executed by instructing the elimination of a paper on a proof tray according to the compared result of a paper size comparison means by using a warning means. SOLUTION: By a jogger mechanism, paper arrangement is executed by actuating a jogger plate based on paper size received from a main body device. A paper existence detection mechanism is set for detecting whether the paper exists on the proof tray and all the bins of a bin tray for sorting and gathering or not and constituted of a pair of light emitting and receiving sensors. When the existing state of the paper of the bin is changed, a signal showing the existence of the bin is transmitted to the main body device. Then, it is detected by the paper existence detection mechanism whether the paper is left in the sorting device 70 or not. When there is the paper in the sorting device 70, the warning display of a message such as 'remove the paper of a sorter' is executed in the message area of an operation part 20. When the removal of the paper is detected, the warning is canceled.

Title: High frequency defreezing device
Inventor: TACHIKAWA HAJIME
IPC: A23L3/36
Filed: 1978-02-24
Abstract: PURPOSE: To conduct proper defreezing independently of density or the like of the defreezed body by stopping the defreezing when the temperature of the defreezed body has reached a proper temperature.  
     CONSTITUTION: In the starting of defreezing, the temperature of a thermistor 5 is the same with the ambinent temperature in a defreezing chamber 1, so that the resistance is low and the temperature detection voltage V1 is low. Because a capacitor 18  is charged, the reference voltage VR of a comparator 21 is zero, so that V1 is larger than VR. Therefore the comparator 21 feeds a high voltage to the coil 28 of a relay 27, leading to closing of a contact 29 and starting of high-frequency heating. The temperature detected by the thermistor 5 falls once and then rises, and it becomes correspondent to the temperature rise characteristic of the defreezed body as the defreezing proceeds. The reference voltage VR increases with the charging of the capacitor 18; when V1<VR is established, the output voltage of the comparator 21 falls to stop the high-frequency heating.

IPC: F16H61/12
Filed: 1993-02-08
Abstract: PURPOSE:To always control properly an automatic transmission connected with a power distribution device having an auxiliary transmission by correcting the detection speed in a second speed detection means on the basis of the detection result in a transmission state detection means. CONSTITUTION:In the normal state of a first detection sensor 11, when a detection signal P1 of a first speed sensor 11 is inputted to a control portion 24 through a changeover means 21, the control portion 24 controls a transmission 1 with the detection signal P1 as one item of the input information. On the other hand, when an auxiliary transmission 3 is HIGH, a detection signal P2 is not corrected and thus outputs as P3 directly. Accordingly, the control portion 24 controls the transmission 1 with P3 as one item of the input information. Then, in the abnormal state of the first detection sensor 11, when the auxiliary transmission 3 is LOW, an auxiliary means 22 corrects the detection signal P2 and the correction result is outputted as the signal P3. The correction means 22, considering reduction ratio of the auxiliary transmission 3, corrects the contents of the detection signal P2 to a rotational speed of an output shaft 1A.

The end edges of the sides of gas G are pushed by the members 60. The pushing load at this time is allowed to act to the end edges of the sides of glass G in such a state that this load is dispersed at two points. Therefore it is not almost caused that one part of the end edges of the sides of glass G is cracked by the concentration of stress.
