Title: Abnormality detecting equipment for driving shaft system
Inventor: MATSUMOTO MOTOO
IPC: H02P29/00
Filed: 1983-01-28
Abstract: PURPOSE:To enable mechanical abnormality such as breakage of the driving shaft joint of a conveying equipment to be easily detected by comparing the signal of a differential current between the main electric currents of a plurality of motors which drive the conveying equipment, with the preset value and by outputting, if they differ with other, an abnormality detecting signal. CONSTITUTION:Signal 24 of a differential current between main electric currents 21 and 22 of a plurality of motors M1 and M2, which drive conveying equipment such as a conveyor or a roller table, is detected by a transducer 20, while the signal 24 of the differential current is converted into d.c. by means of a rectifier 23 and is smoothed out by a smoothing circuit 25. A differential current signal 27 from the smoothing circuit 25 is compared with the preset value by using a set circuit 26. If the both differ with each other, an abnormality detecting signal 28 is output by using a switching circuit that is built-in in the circuit 26. Thus, a mechanical abnormality such as breakage of a joint for a driving shaft or wear-down or sticking of a bearing of the conveying equipment can be found easily.

Filed: 1979-02-04
Abstract: PURPOSE:To prevent leakage of a fluid perfectly and enable removing yokes and a magnet easily as necessary for conducting inspection of and maintenance work for the interior of a housing, by sealing with a magnetic fluid both the shaft side portions and housing side portions of the yokes. CONSTITUTION:An annular magnet 11 is held between intermediate portions of annular yokes 12, 13. The yoke 13, which is one of the yokes 12, 13, is spaced slightly at its whole outer and inner circumferential surfaces from housing 14 and a shaft 15, respectively. The other yoke 12 is fixedly fitted in a suitable manner into the housing 14, and slightly spaced from the shaft 15. A magnetic field 16 is injected into narrow gaps between the yoke 13 and housing 14 and between the yoke 13 and shaft 15. Assuming that the housing 14 and shaft 15 consist of a ferromagnetic material, a magnetic flux from the magnet 11 is bifurcated to flow to the housing 14 and shaft 15. As a result, the magnetic flux is collected in the narrow gaps at the inner and outer circumferential surfaces of the yoke 13 so that the magnetic fluid  16 injected therein displays its sealing effect.

Title: Bond issuing device
Inventor: MOROSAWA AKIHIRO
IPC: G07B1/00
Filed: 1989-01-20
Abstract: PURPOSE:To prevent a bond from being erroneously issued by an artificial miss by successively reading a number, which is described on the issued bond, by a reading means and successively collating this number with a number in a storing means. CONSTITUTION:An inserter part 5 takes in a reception slip, to which bond issue data such as the type of the bond and the number of the bonds to be issued, etc., are registered, and reads the recorded bond issue data. Then, the data are written to a memory in a control part 7 and the type of the bond to be issued and the number of the bonds to be issued are discriminated from the read bond issue data. According to these data, the control part 7 extracts the bond to be issued out of the bonds housed in a housing part 2 and carries out the bond one by one from the housing part 2. When the carried-out bond is passed through a reading means 6A, the data such as a bond number, etc., described on the surface of the bond are read and kept in the memory of the control part 7. Next, the bond number kept in the internal memory of the control part 7 is compared with the bond number to be read just now to decided whether the both numbers are coincident or not. When the both numbers are not coincident, the display of an error message is executed.

Title: Optical switch device
Inventor: MORI YASUSHI
IPC: G02B6/35
Filed: 1980-02-03
Abstract: PURPOSE:To maintain excellent matching precision and to simplify the operation by opposing end surfaces of a couple of optical fibers to each other all the time by an elastic body, and by excluding a light transmission line by deforming the elastic body by pressure. CONSTITUTION:A couple of optical fibers 1 are arranged opposing to each other at any time by elastic body 5. At need, liqud 6 with a refractive index greater than that of elastic body 5 and equal to that of a core part is sealed in and elastic body 5 is pressurized by pressurizing mechanism 7 to close the part of liquid 6. Consequently, light transmitted via optical fibers 1 and liquid 6 is occluded. When liquid 6 is not sealed in, one end of elastic body 5 is displaced via displacing mechanism 8 to cut off the transmitted light. As the pressure is releaved, elastic body 5 is restored, so that while the excellent matching precision is maintained, the operation is simplified.

IPC: H03H17/02
Filed: 1981-01-29
Abstract: PURPOSE:To prevent the extension of operation error and deterioration in S/N and to simplify circuit, by attenuating output gain at the final stage and making the operation for gain adjustment of a digital filter with a figure corresponding to a large signal level. CONSTITUTION:When a differential equation of a digital attenuation equalizer by means of a digital filter is expressed as equation (1), coefficients a0, a1, a2 in equation (1) are replaced as a0=A0K, a1=A1K, and a2=A2K, and the result  of replacement is divided by K, resulting in equation (2a). When the output gain  of the digital filter is attenuated, since K is smaller than 1, Yn in equation (2a), i.e. an output obtained from an adder 19 is greater than the Yn. The Yn of the  adder 19 is multiplied by K at a multiplier 20 to obtain a new output signal Yn  and this is given to an output terminal 7, allowing the operation at a greater  signal level. Thus, signal processing can be made without extension of operation  error and deterioration in S/N.

Title: Humidity controller
Inventor: KAWAMURA TAKEYA
IPC: G05D22/00
Filed: 1993-01-28
Abstract: PURPOSE:To reduce the size and weigt of the whole device by preparing a section for executing both of heating and cooling in an air passage requiring humidity control and removing/applying humidity in the section. CONSTITUTION:Air sucked from a chamber 1 by a pump 2 is temporarily stayed in a humidity control chamber 3. In the case of applying humidity, moisture 13 (hatching part) is supplied from a water tank 4 to the chamber 3 through a valve 6, and when a thermoelectric element 5 is operated in a heating mode, moisture 13 in the chamber 3 is evaporated and the air in the chamber 3 is humidified. The humidified air is returned to the chamber 1 through a valve 15. On the other hand, in the case of removing humidity, the element 5 is operated in a cooling mode, so that moisture in the air is dew-condensed and the dew-condensed moisture is returned to the tank 4 through a valve 14 to recover the moisture. Thus the air from which moisture is removed is returned to the chamber 1 through a valve 16.
