Title: Method and apparatus for detection of exposure amount of gas
Inventor: TAKAHASHI RYOJI
IPC: G01F1/00
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus in which the exposure amount of a gas is detected with good operability. SOLUTION: A specific kind of gas which flows in a conduit 10 is diffused toward one end from the other end of an indicator 13. An indicator layer 16 on the indicator 13 is discolored in a part which comes into contact with the gas, i.e., toward one end from the other end of the indicator 13. When the indicator 13 is irradiated with light from a light source 20, a quantity of transmitted light which is transmitted through a discolored part in the indicator layer 16 and that which is transmitted through an undiscolored part are different while a discoloration boundary is boundary is used as a boundary. Consequently, a light receiving element 21 is moved by a movement means 22 along the indicator 13 together with the light source 20, the transmitted light is received by the light receiving element 21, and the discoloration boundary can be detected.  Since the position of the discoloration boundary is proportional to the exposure amount of the gas, the exposure amount of the gas can be detected on the basis of the discoloration boundary.

Title: Cycloconverter device
Inventor: TATARA SHINJI
IPC: H02P27/16
Filed: 1990-08-09
Abstract: PURPOSE:To make high power factor operation possible making the best use of the feature of asymmertrical control, without raising the secondary voltage of a transformer, even in the case of driving a synchronous motor by low voltage, by changing the value of constant voltage along with changing beta limit according to the amplitude of phase voltage. CONSTITUTION:Low-voltage output voltage EVL at below the speed N(Valpha) of a synchronous motor and output voltage EUH at speeds exceeding N(Valpha) in time of a constant voltage Valpha are shown by the figures. By these characteristics, in the low-voltage region, it becomes possible for beta limit to cancel sufficiently by enlarging the beta limit and by suppressing asymmetrical fixed-side voltage low, as inversion operation is done during half-cycle periods. And in the high-voltage region, it becomes possible to commutate safely by making the beta limit smaller and the symmetrical fixed-side voltage higher, as the inversion operation region becomes narrower and current value commutable in this region becomes smaller compared to a maximum peak value. Incidentally, the beta limit can also be changed continuously corresponding to an output voltage reference or speed signal.

IPC: H03H9/44
Filed: 1982-12-01
Abstract: PURPOSE:To avoid being influenced by such secondary effects as a reflection a spurious excitation, etc. and to correct easily a characteristic by constituting so that an elastic surface wave is propagated through other propagating paths being parallel to each other in accordance with frequency. CONSTITUTION:Chirp type electrodes 8, 8' on which electrode fingers 7, 7' and buses 6, 6' cross with each other diagonally are used for input/output electrodes. Between these electrodes and reflecting lattices 4, 4', an elastic surface wave is propagated through different propagating paths being parallel to each other in accordance with frequency, crosses and passes through the electrode finger and the reflecting lattice for other frequency, and avoids receiving bad influence such as a reflection, a spurious excitation, etc. Also, since the chirp type electrode is used, the weighting of the electrode crossing width can be executed, therefore, a side lobe, flatness in a band, etc. are corrected easily, and the input/output impedance also does not become large.

Title: Focusing detecting device
Inventor: SUZUKI TAKEOMI
IPC: G02B7/34
Filed: 1982-12-01
Abstract: PURPOSE:To detect exactly a focused position by providing a phase plate in the vicinity of a photodetector train face, correcting a distortion, and making an image forming face coincide exactly with the photodetector train face, in a device for detecting a focused position of an image forming lens. CONSTITUTION:Photodetectors 5A, 5B, 6A and 6B are vertical to a paper surface, are arrayed in parallel to each other and are on the same plane 7. An image forming face 8 of two split luminous fluxes generates a step difference between the two luminous fluxes concerned by a phase plate 4, and also generates a distortion by an aberration, etc. generated generally in a luminous flux splitting means. For instance, in case when photodetector trains 5, 6 are parallel and consist of plural trains, and a distortion of the image forming face 8 is regarded as almost uniform in the direction of the photodetector train, a phase plate 9 is constituted of a face which is uniform in the direction of the photodetector train and whose direction is changed discontinuously, the distortion of the image forming face is nearly corrected only on each photodetector, and an image forming face 10 is obtained. Also, it is not always necessary that the phase plate 9 covers all the photodetector trains, and as a matter of course, the distortion of the image forming face 10 can be corrected in the same way by covering only a part of the photodetector trains.
