Title: Odorless stool
Inventor: NAKAMURA TAKAO
IPC: E03D9/05
Filed: 1990-11-29
Abstract: PURPOSE:To install a stool in a living room because of odorlessness by connecting a pipe for ventilation to a washing pipe for connecting a washing water tank to a stool, or directly connecting the same to the stool to prevent odor from being diffused in the toilet. CONSTITUTION:When a ball valve 2 is raised, water in a washing water tank 1 is passed through a washing pipe 3 to enter a conduit 7, and the water is jetted from a lot of nozzles 8 to wash away dirt. An indirect ventilating pipe 11 is connected to the washing pipe 3 to suck odor generated in a stool from the nozzles 8 for washing water backward, and the odor is discharged to the outside by a ventilating fan 10 through the washing pipe 3 and the indirect ventilating pipe 11. As the air in the toilet in addition to the odor generated in the stool is sucked through the stool, a user, does not sense odor. Accordingly, the stool can be installed in a living room, and in the winter, the worries of going to the cold toilet can be eliminated so as to reduce a burden of an old man, a sick person and an attendant.

For example, as the material 3, one of Mo, W, Au, Pt, Rh and so on, is used, and as the material 4, one of C, Si, Be, Al and so on, is used. The soft X-rays is intensified by reflected X-rays from each layer of the multilayered film 5 and interference is induced and thereby a strong reflected X-ray can be obtained, on the whole, and, at the same time, transmitted X-rays which pass through the multilayered film 5 penetrate furthermore the thin film 2 and thereby the transmitted X-rays can be obtained. Consequently, the soft X-ray beam can be splitted in at least two directions.

Abstract: PURPOSE:To accurately measure the dimensions of a room in a short time without requiring experience and skill by generating pulses respectively proportioned to the rotational angle of a rotary table and length of a drawn-out tape and counting the number of the pulses. CONSTITUTION:Up-down counters 36 and 37 are initialized to '0'. While the leading edge of a tape drawn out from a linear encoder 13 is brought to the corner of a room, two-phase pluses are respectively counted 36 and 37 by a number proportional to the relative rotational angle between a rotary table and pedestal generated from a rotary encoder 11 and a number proportional to the moving amount of the tape from the encoder 13. After the leading edge of the tape is set to the corner of the room, the data of each count value 36 and 37 are read 31. This operation is performed on all corners of the room and obtained data are stored 34. After one room, the same measurement is repeated to other rooms. By connecting this room dimension measuring instrument to external equipment 4 through an SIO 35, each stored 34 data are read out at every room and coordinate transformation 4 is performed on the data. Since the transformed data become polar coordinate data, with the center of the polar coordinates being set at the installed location of this measuring instrument, the actual shape of the rooms are measured by finding lengths of opposite sides of the rooms.
