Title: Structure for reducing axial thrust of centrifugal pump
Inventor: TAKAHASHI SHINICHI
IPC: F04D15/00
Filed: 1990-11-30
Abstract: PURPOSE:To increase a pressure increasing of a wearing ring near an axial vane wheel and reduce a variation of an axial thrust by a method wherein a clearance amount between the wearing ring and a side wall of the vane wheel is larger than an amount of clearance between the wearing ring and a casing wall perpendicular to a rotating shaft. CONSTITUTION:As an axial position of a vane wheel is moved toward a direction A as shown in a figure, a part of a clearance 7 is enclosed by an overlapped part of a wearing ring of a front side wall 1a, a wearing ring 3 and a casing 2, resulting in that an amount of clearance (d) is remarkably reduced, so a back pressure is applied to the part of the clearance 7. Since a clearance amount of the clearance 6 is larger than an amount of clearance (d), a discharging pressure P6d at the clearance 6 is higher than that of a general type pump under an influence of an increased pressure at the clearance 7. With such an arrangement, a pressure distribution between a side wall of the vane wheel and the casing wall is entirely increased and as a result it is possible to reduce a variation in axial thrust generated under a displacement of the axial position of the vane wheel.

Filed: 1988-12-26
Abstract: PURPOSE:To eliminate the filtering time of the filtering system to exclude floating dust in a closed vessel by coating the inside surface of the closed vessel with an adhesive material to catch dust floating in the vessel. CONSTITUTION:An inside surface 2 of the closed vessel is coated with an adhe sive material 1 to catch dust floating in the vessel. For example, when the surface is coated with the adhesive 1 of high adhesion in the case of an air current shown by an arrow 3, dust is caught by only contact to the adhesive surface and is neither scattered nor floated again. Thus, dust floating in the vessel is stuck and is not floated again, and all of dust coming into contact with the surface of the vessel is stuck through air drifts.

CONSTITUTION:When a case body cover is opened during recording paper being replaced with new one a thermal head 2 is separated from a platen roller 3, and a rotary shaft 13 is inserted into a new recording paper roll P, and placed on a bearing 5a. Then, paper Pa is pulled out, and its top edge part which passes through a printing unit 1 is placed on a recording paper receiving plate 11, and a case body cover is closed, and then the head 2 makes contact with the roller 3, and an electromagnetic clutch 3a is put OFF, and a motor 4 is turned reversely. Accordingly, the roll P is turned in the clockwise direction, and the paper Pa is rewound in the B direction. In this case, the top edge of the paper Pa is shifted to a lower part guide plate 8a from the receiving plate 11, and a sensor 6 is detected, and a motor 4 is stopped at the point of time when the head 2 reaches this side of a recording line. In this rewinding generation of slack is prevented, because the recording paper Pa is taken up on the roll P.

Title: Method and device for measuring time interval
Inventor: SOGA HARUAKI
IPC: G01R29/00
Filed: 1991-12-13
Abstract: PURPOSE:To enable positive and negative time to measurement even if there is an unneeded signal within a signal to be measured by generating a delay signal which is shorter than a generation cycle of a timing signal and then measuring time from the generation to generation of the signal to be measured. CONSTITUTION:A signal 100 is input to a delay means 1 by an index signal (cycle time T) which is generated by a motor etc. The means 1 allows a generation timing of the signal 100 to be delayed by a certain time Td (<T) and a delay signal 101 to be input to a counting means 7. A signal 104 is input to the means 7 by the signal to be measured (measurement end signal) which is generated being related to the signal 100. The means 7 monitors the signals 101/104 and then starts/ends counting when counting start/end conditions are met. Counting is performed by counting a reference clock 106. A measurement result processing means 8 reads a count result value by collecting the count data 112 from the means 7 and then converts it to time. Then, a time which is obtained by subtracting a time T-Td from a count result time which is time- converted becomes a measurement result.

Title: Fifo memory-incorporated voice synthesis lsi
Inventor: HOTEI TOSHINAO
IPC: G10L19/00
Filed: 1992-12-11
Abstract: PURPOSE:To improve the development of a data processing program by incorporating a FIFO memory into a voice synthesis LSI which outputs voice waveform signals. CONSTITUTION:In order to generate a synthetic voice, a host CPU 11 inputs instructions to a voice synthesis section 12, data are read from a voice digital memory 13, time sequential data values of voice waveforms are computed by the data processing program of a voice synthesis section 121 and are successively inputted to a FIFO memory 122. When the section 121 gives read clock signals with a prescribed period to the memory 122, the memory 122 inputs time sequential data values stored in the memory 122 to a D/A converter 123 at a constant period. The converter 123 converts the time sequential data into analog voice waveform signals and a voice is generated from a speaker 16. Thus, the limitations imposed on the number of instruction steps and timing of time sequential data values are eliminated while conducting the development of a data processing program.
