Title: Treatment of water by electrolytic deionization method and device used therefor
Inventor: KOYAMA HIROYOSHI
IPC: C02F1/469
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To excellently control the operation to produce treated water in accordance with the amt. of water to be used at the time of electrolytically deionizing water by operating an electrolytic desalter and sending the treated water to a treated water feed line or treated water ciculating line in accordance with the supply of treated water. SOLUTION: When treated water is supplied to produce ultrapure water, the water to be treated from a feed line 12 is filtered by a pretreating device 9 and then introduced into a filtered water tank 13. The filtered water is then passed through a reverse-osmosis membrane device 10 and desalted, and the hardness component is separated and removed. The water is separated into permeated water and concd. water (RO concd. water), the permeated water is sent to an electrolytic desalter 11, and the RO concd. water is discharged from a line 24 or circulated to a high-pressure pump 14 through a concd. water circulating line 26 and a concd. water and electrode water circulating line 22. At this time, a three-way valve 19 is switched by the electric signal of a level switch 30, and a high water quality is maintained.

Title: Automatic exposure adjusting device
Inventor: HARUKI TOSHINOBU
IPC: H04N5/238
Filed: 1989-09-12
Abstract: PURPOSE:To prevent a screen from being dark by comparing the brightness level of a priority area with that of a nonpriority area and increasing the priority of the nonpriority area when the priority area is discriminated to be in a bright forward light state to limit excess correction. CONSTITUTION:An image picking-up screen is divided into areas A1-A6, in which the area A1 is located in the center of the pattern, the area A2 is located on the outer periphery of the area A1 and further the areas A3-A6 are arranged on the circumference of the area A2. Then the highest priority is given to the area A1 where a major object exists with high possibility and the 2nd priority is placed on the area A2. When the brightness level of the area A1 having the higher brightness is larger than the brightness level of the areas A3-A6 with smaller priority, the priority of the areas A3-A6 with smaller brightness level is increased to apply the adjustment of the exposure. Thus, excess correction with respect to the area of excessive forward light is limited to prevent that the entire screen is dark.

Title: Hot-water supplier
Inventor: KURACHI YASUHIKO
IPC: F24H9/12
Filed: 1987-09-21
Abstract: PURPOSE:To prevent the seasonal fluctuation of a supplying hot-water temperature as well as the generation of noise, by a method wherein the title supplier is provided with a guide pipe, guiding water, guided through a lower check valve, into a bubble pump through a pipe wall after effecting heat exchange between the water and water in the bubble pump. CONSTITUTION:When power is supplied to an electric heater 24a, water in a bubble pump 20 is heated and boiling is started, whereby a pressure in the pump 20 is increased and an upper check valve 26 is opened. Accordingly, the hot-water is sent out to the upper part of a hot-water reserving tank 11 through the upper check valve 26. On the other hand, bubbles, produced by the boiling, ascend to the vicinity of the outlet port of a guide pipe 39, then, the bubbles are cooled by water in the outlet port and are condensed. When the bubbles are eliminated, the pressure in the pump 20 is reduced and water flows into the pump 20 from the lower part of the hot-water reserving tank 11 through a lower check valve 25. The temperature of this feed water is increased during passing through the guide pipe 36 by heat exchange effected between high-temperature water in the pump 20. According to this method, the fluctuating width of the temperature of the hot-water, sent out of the bubble pump 20, may be reduced even when the temperature of water, supplied into the hot-water reserving tank 11 through a feed water pipe 14, is fluctuated due to the change of season; further, the rupturing sound of bubbles may be reduced much more.

Title: Moving picture compression device
Inventor: ISHIKAWA HIROYUKI
IPC: H04N19/527
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To provide a moving picture compression device in which the number of frames that are actually compressed can be reduced and smooth movement can be realized without deteriorating picture quality. SOLUTION: A movement retrieval means 12 obtains with which part in a reference frame the respective blocks of a present frame has high correlation. A distance to the block having the highest correlation is set to be the moving distance of the block from the reference frame. A movement judgment means 13 obtains the total of moving quantity in a whole screen based on the moving distances of the respective blocks and judges whether the present frame is a picture having movement or not. When the present frame is judged to be a picture with less movement, a processing up to the movement judgment means 13 is executed by the previously decided number of frames. Then, the compression processings of a frequency conversion means 14 and subsequent means are executed after the number of frames exceeds the previously decided number.  When the picture of much movement is detected in the movement judgement means even if the number of frames does not continuously satisfy the previously decided number, the compression processing is executed without a system waits for the previously decided number of frames.
