Title: Device for purifying water
Inventor: NISHITANI JUNICHI
IPC: B01D61/18
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To largely reduce the channel resistance, namely the pressure loss, and to obtain a required water-sealing flow rate without increasing the membrane area of a hollow fiber membrane by providing a water-guiding pipe inside the hollow fiber membrane of a water-sealing injection filter consisting of an ultrafiltration membrane. SOLUTION: The water-guiding pipe for deriving sealing water through a hollow fiber membrane toward an outlet side is provided inside a portion where a number of hollow fiber membrane are arranged in a water-sealing injection filter 18. Water where a floating substance containing a fine particle through the hollow fiber membrane of the water-sealing injection filter 18 consisting of an ultrafiltration membrane is captured and eliminated is divided into a part for directly flowing to the outlet of the water-sealing injection filter 18 from the hollow fiber membrane and a part for flowing to the outlet through the water-guiding pipe after entering the water-guiding pipe through a header part from the hollow fiber membrane. As a result, water is branched into two directions in the hollow fiber membrane and flows.  The pressure loss increases as the inner diameter of a transmission water-guiding pipe 1 is smaller up to 18 mm. On the other hand, when the diameter reaches 8 mm or larger, the inner diameter should preferably be 18 mm or larger to the extent that the pressure loss does not practically interfere with use.

Title: Mounting and dismounting device for manhole lid for escalator
Inventor: OKAMURA TORU
IPC: B66B23/00
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To mount and dismount a manhole lid safely without using a T-shaped handle by storing a handle main body below a top face of the manhole lid at the time other than the time when the manhole lid is mounted or dismounted. SOLUTION: When it is desired to mount and dismount a manhole lid 2, a person in charge of maintenance puts his hand in taper parts 10, 10a to grip a handle body 5 and lift it, and the handle body 5 jumps up from a recessed part 9. The person in charge of maintenance grips the handle body 5 firmly and lifts it in this condition to remove the manhole lid 2 from an opening part. In this case, nuts 7, 7 serve as stoppers so that rod bodies 6, 6a do not come off the manhole lid 2. Moreover, when the handle body 5 jumping out of the recessed part 9 is stored in the recessed part 9, the handle body 5 enters a condition shown in the drawing and does not protrude from a top face of the manhole lid 2, thereby ensuring the safety.

Title: Printer
Inventor: KAMIMURA NAOYA
IPC: B41J11/02
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To rapidly raise temperature of a platen to desired temperature in the case of bringing about necessity of raising the temperature of the platen by providing a printing head moving control means for disposing the head in a printing area of the platen at the time of raising the temperature of the platen by a platen temperature control means. SOLUTION: When an OHP mode is selected, a speed of a fan 14 is decelerated, control temperature of a platen in the mode is set. Preheater 34 and main heater 35 are controlled via a heater circuit 26 based on sensed temperatures of pre-thermistor 30 and main thermistor 31 so as to arrive at a set control temperature. A carriage placing a printing head is moved to a center in a printing area of a platen and steadily stopped. Since a printing head 13 disposed within the area is heated by a head heater, the platen or particularly main platen is heated by radiation heat dissipated from the head 13, and hence can be rapidly raised to the set temperature.
