Title: Production of ceramics port liner
Inventor: HAMANAKA TOSHIYUKI
IPC: B28B1/26
Filed: 1987-10-13
Abstract: PURPOSE:To produce a ceramic port liner having accurate valve holes, by forming water-impermeable faces having a profile corresponding to the valve hole on the inner surface of a water-absorptive mold and pouring ceramic slurry thereinto. CONSTITUTION:Water-impermeable faces 4 having a profile corresponding to a valve hole is formed at the positions corresponding to the valve holes of the inner surface 3 of a mold 1 made of gypsum or water-absorptive resin. The water-absorptive molds 1, 2 are closed and ceramic slurry is poured thereinto. The moisture of the slurry in contact with the inner surfaces of the molds 1, 2 is absorbed by the mold, and the slurry gradually deposits on said inner surfaces. Since, however, the water-impermeable faces 4 cannot absorb the moisture, no slurry deposits on these faces at all. Accordingly, when the slurry remaining after the deposition is drained and the molds 1, 2 are opened, a port liner 6 having opened valve holes 5 can be produced.

Abstract: PROBLEM TO BE SOLVED: To improve operability of a door opening handle by arranging each lock device on the front and rear sides of a sliding door, unlocking the lock device by the lever operation of the door opening handle of the door, and rotating a fifth handle always in the same direction. SOLUTION: The automatic opening and closing device is composed of a fourth lever unlocking a rear side auto-lock device rotated by the door opening operation of inner and outer door opening handles 24a. In addition, it is rotated by each door opening operation and constituted of a fifth lever stopping the auto-lock of the rear side auto-lock device. At the time, even if the inner door opening handle 24a and the fifth lever are rotated in either side of the door opening handle 24a, it is the automatic opening and closing device connected for rotating the fifth lever in the same direction. A third lever and a sixth lever 54 are fixed on the rotary shaft 24 of the inner door opening handle 24a, and an arc oblong hole 58 centering the rotary shaft 24 is connected to the fifth lever.  Thereby even if either side rotation of the inner door opening handle 24a is performed, the fifth lever is rotated and it can be easily performed.

Title: Bath purifier
Inventor: TAKETSU SHINJI
IPC: A47K3/00
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To stably maintain a cleaning performance by providing an informing means for requesting a circulating path including a filter tank to be cleaned when a flow rate detecting means detects the descrease of flow rate. SOLUTION: When a purifying operation continues for a long period, scale is accumulated in a circulating means 3, a reciprocating pipeline 2 or a filter tank 6 and a circulating flow rate is gradually lowered. When the circulating flow rate is lowered, the quantity of bathtub water passing through the filter tank 6 per unit time is decreased, so that a purifying performance is lowered. Thus, assuming that the purifying performance can completely meet the decrease as low as about 20% of the circulating flow rate, for instance, when an initial circulating flow rate during the start of operation is 20l/minute, a flow rate informing means 4 detects that the circulating flow rate reaches about 16l/ minute and informs a user of it and an informing means 9 informs a user of a time of cleaning.
