IPC: G06F3/12
Filed: 1985-05-14
Abstract: PURPOSE:To facilitate control of printing space by handling informations concerning dot images and the informations on printing spacing related to the former as the sets of integral informations. CONSTITUTION:A memory means 1 stores a dot image information and a printing spacing information as a set. Corresponding to a character code designated by an application program, a dot image information and a printing spacing information are read out from the memory means 1, and the dot image information is put out to a dot image printing means 3, and the printing spacing information is put out to a blank printing means 4 seperately. The dot image printing means 3 controls a printer to print the information received as a dot image.

IPC: H01L27/14
Filed: 1988-04-25
Abstract: PURPOSE:To reduce a crosstalk by forming a first conductivity type high impurity-concentration region to a first conductivity type layer section positioned just under a first conductivity type layer isolating adjacent second conductivity type layers.

Title: Membrane treating device
Inventor: SHIOYAMA MASAHIKO
IPC: C02F1/44
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To scrub the face of a membrane with a corresponding amt. of air to the contamination of the membrane and to improve the power consumption by controlling the number of the blowers to be operated to supply air to a diffuser based on the pressure difference between the membranes of a membrane module. SOLUTION: The pressure on the suction side of a pump 13 (the pressure proportional to the pressure difference between the membranes) is measured by a pressure gage 14, the measured pressure is transmitted to a controller 15, and the number of the blowers 9 to be operated is controlled by the controller 15 based on the measured pressure. The number of the blowers 9 is controlled so that the sufficient amt. of air to scrub the face of the ceramic membrane in the initial operation of the membrane treating device of a membrane module 4 is diffused. For example, when the ceramic membrane is not contaminated and the pressure value is R0, only one blower 9 is operated, and, when the ceramic membrane is gradually contaminated and the pressure value is lowered to R1, two of the blowers are operated.  When the ceramic membrane is further contaminated and the pressure value is lowered to the specified value R2, all the blowers 9 are operated.

Filed: 1995-04-27
Abstract: PURPOSE: To enable rewinding without stopping a rewind operation, at the time of changing a rewind speed even after the rewind operation was started by varying the range of the rewind speed capable of switching in response to a detected power supply voltage. CONSTITUTION: A microcomputer 1 systematically controls the operation of a camera in accordance with a program stored in an incorporated ROM and measures the voltage of a power supply battery 18. Further, a feeding control circuit 10 outputs a feeding speed control signal to a film feeding motor, to switch the speed reduction ratio. When a middle speed as the present speed is of a maximum speed capable of feeding the film, at the time of turning on a rewinding switch 13, the speed is temporarily changed to a minimum speed. On the other hand, when the film can be fed at a higher speed, a speed reduction gear is switched to a high-speed side, to feed the film.  When the film is rewound at the middle speed, the rewinding switch 13 is turned on again and it is discriminated whether the speed is to be increased to the middle speed similarly or the present low-speed driving is to be maintained.

Title: Removal of arsenic and silicic acid present in industrial waste water
Inventor: CHIBA SHIGEHIKO
IPC: C02F1/28
Filed: 1978-08-29
Abstract: PURPOSE: To remove arsenic and silicic acid present in industrial waste water inexpensively by adding ferrous salt to the waste water containing dissolved arsenic and silicic acid therein, oxidizing ferrous salt and arsenic with an oxidizing agent and adjusting the pH within the predetermined range.  
     CONSTITUTION: Arsenic ane silicic acid entrained in steam for geothermal electric power generation are dissolved in feed water 1 wihtin a mixer. An oxidizing agent such as H 2 O 2  and ferrous ion are added to the feed water to oxidize at least 40% of the ferrous ion to ferric ion and at the same time arsenious ion to arsenic ion. The pH of the solution is adjusted with an solution of NaOH to 2.5W5. Arsenic and silicic acid together with ferrous salt and ferric salt are precipituted as a co-precipitate 6. If necessary, a coagulant 7 is added to the solution to aggregate the co- precipitate 6 which is then introduced into a settling separator 8. The coprecipitate 6 is separated by means of a dehydrator 10 and the dehydrated liquid is recycled to use. As compared with prior art, the amounts of agents used can be reduced and the amount of the residual arsenic present in the waste water can be reduced to below 0.05 ppm.
