Title: Vertical pipe for sewage
Inventor: YAMADA YONEKAZU
IPC: E02D29/12
Filed: 1994-07-28
Abstract: PURPOSE:To buffer sewage being on the way of dropping by arranging shielding plates for partially shielding each flow passage in a short pipe in a vertical pipe body in a zigzag-shape. CONSTITUTION:In short pipes 2 which are inserted in a sewage vertical pipe body 1 and stacked up, a shielding plate 21 to shield the half of a flow passage in the short pipe 2 is about horizontally projected and integratedly provided. A small hole 22 is provided in a pipe wall near the root part of the shielding plate 21 to lead in air through a clearance between the main pipe 1 and the short pipe 2 under the force of the sewage flowing down in the pipe for facilitating the smooth flowing down of the sewage without its disturbance. The shielding plate 21 in each short pipe is arranged in a zigzag-shape in the vertical pipe body 1. When one end of a sewage pipe 4 is introduced into an underground structure 3 and connected to the upper end of the vertical pipe body 1, since the sewage flowing from the sewage pipe 4 into the vertical pipe body 1 flows down zigzag, the dropping impact of the sewage onto the bottom of the underground structure 3 is weak, and does not damage the bottom.

Title: Magneto-optical recording medium
Inventor: SHIMIZU TADASHI
IPC: G11B11/10
Filed: 1989-07-10
Abstract: PURPOSE:To always realize recoding or erasing in high efficiency by providing a layer comprising superconducting material adjacent to a recording layer. CONSTITUTION:The superconducting layer 2 is provided adjacent to the recording layer 4 in the medium. When the superconducting layer 2 is provided in this manner, the layer 2 shows perfect diamagnetism, namely, Meissner effect which inhibits magnetic flux 29 of the magnetic field produced by a coil 17 from penetrating the superconducting layer 2 and makes the flux pass through a window 7 of superconductivity. Therefore, even when vertical fluctuation of the medium is rather large, Meissner effect of the superconducting layer is strong enough against the influence of changes in the magnetic field due to vertical fluctuation of the medium. Thereby, the outer magnetic field applied on the medium on recording or erasing concentrates near the recording layer and shows little changes near the recording layer. By this method, recording or erasing can be performed efficiently under any conditions without applying excessively large magnetic field on the medium.

CONSTITUTION:As a humidity in a bath room 1 is increased up to its specified humidity, a dew formation is found at an inner wall surface of the bath room 1 (a point (a)). At this time, a dew formation is also found at a dew formation sensor 5 to detect that the wall surface is in its dew formation and then this is outputted to a ventilation fan control device 6. This output is received and an electrical energization is applied to a weak tap of a motor 8 for the ventilation fan 3 and then a low operation is carried out. Upon completion of taking a bath (a point E), the low operation is continued, a humidity is decreased and finally decreased down to its initial humidity state, resulting in that the dew formation at the wall surface is also started to be diminished. At this point (b), the dew formation at the dew formation sensor 5 is similarly diminished and it is judged that the wall surface is dry and then an output of the sensing signal for the ventilation fan control device 6 is stopped. The ventilation fan control device 6 judged that the ventilation fan 3 should be operated under its high load operation, the operation is carried out for a specified period of time and then the operation is stopped.

Abstract: PURPOSE:To process an optional communication picture among many and unspecified terminals by using a control signal channel set between a picture communication terminal and a wide-band switchboard and attaining transmission/ reception of picture processing signals between terminals or between the terminal and the switchboard in a picture communication mode. CONSTITUTION:One of two picture communication terminals 1 uses a control signal channel 8 while the communication is performed between both terminals 1 via a picture signal channel 7. Thus the picture processing control signal is transmitted to a picture processing control unit VPC6 for output of a picture processing request. Then the VPC6 gives an indication to the CPU of a wide- band switchboard 4 to give an interruption of the picture signal channel of a picture editing processing unit VPU5 to the channel 7 and obtains a connection state as shown in the diagram. Under such conditions, the VPU5 is connected to the channel 7 of both terminals 1. While both terminals 1 are connected to the VPC6 via the channel 8. Thus it is possible to give picture processing to an optional picture which is under communication between both terminals.
