摘要： PURPOSE: To reduce a noise to a level where a noise due to the dimming of a inverter is not a problem even in silent environment by arranging an insulating member having an air ventilation passage and a sound absorber above or below an inverter substrate. CONSTITUTION: The insulating member 42 which has the air ventilation passage and the sound absorber 41 are arranged above or below the inverter substrate 8. When a top cover is lifted as shown by an arrow to input characters, a liquid crystal display screen, i.e., the whole LCD unit 2 is raised. At this time, the whole inverter substrate 8 is raised and the reverse side of the inverter substrate 8, therefore, faces the user. Namely, when the information processor is used, the sound absorber 41 is arranged in a direction wherein a sound is easily heard. The insulating member 42 of a thin plastic sheet has the air ventilation passage by providing a saw-tooth space, so this member prevents the temperature of the inverter substrate 8 from rising and the substrate 8 from being short-circuited.

摘要： PURPOSE:To reduce the load of a CPU and to increase a processing speed by shifting write data by the CPU. CONSTITUTION:An adjacent address generating means 102 is provided to an address circuit of a graphic memory 206 as well as a CPU 201 and therefore two writing jobs are carried out to the memory 206 with a single writing process of the CPU 201. In this case, the write address received from the CPU 201 is used for one of two writing jobs to the memory 206 with the adjacent address of the means 102 used for the other writing jobs respectively. Thus data can be written in an (n) address and an (n+1) address of the memory 206 even in case the head position of the data is shifted and the replaced data covers the addresses of two words of the (n) and (n+1) addresses when the CPU 201 updates the data on the (n) address of the memory 206. Thus it is possible to reduce the processing load of the CPU 201 and to increase the processing speed.

摘要： PURPOSE:To improve removing performance of deposit on sand grain surfaces and decrease the abrasion of the apparatus by colliding high-velocity sand grains against the thin sand grain film layers formed by pressing sand grains to the inside wall of a rotating cylinder by centrifugal force. CONSTITUTION:Annular weirs 5 which are taller the nearer to the outer side are secured in plurality concentrically to the top surface of a rotating disc 4. The used molding sand 3 charged onto the used sand receiving tray 2 in the upper part of a vessel 1 is led to the top surface in the central part of the rotary disc 4 and receives rotating motion by the rotary disc 4 which is being rotated at a high speed by a motor 12. Centrifugal force causes the used sand to fly in the normal direction and to collide against the annular weirs 5, thereby forming thin sand grain layers 6 successively from the inner side. In this case, the used sand scattered in the normal direction collides with the thin sand grain films 6 and makes colliding abrasion between the sand grains, thus the sand grains successively repeat collision action toward the outer side, and during this time, the deposits on the sand grain surfaces are ground away. The reclamation sand 7 accumulates in the bottom of the vessel 1 and is taken out through an outlet 8.

摘要： PURPOSE:To reduce the produced quantity of surplus sludge through efficient performance of waste water clarification and self-digestion of active sludge by a method wherein waste water treated in the first aeration tank is guided into the second aeration tank where aeration is conducted to digest biological solid in active sludge. CONSTITUTION:Waste water 13 contg. soluble organic material is guided, together with returned active sludge 27, into the first aeration tank 16 where aeration is performed to reach a 90% or more soluble BOD removal ratio. Then, treated waste water 19 contg. active sludge is introduced into the second aeration tank 20, where aeration is conducted until the active sludge concentration becomes lower at the outlet of the second aeration tank than at its inlet, which means sufficient digestion of biological solid in the sludge. Then, the water is guided into a settling tank 24 and solid and liquid are separated.

摘要： PURPOSE:To improve the activity of microorganism and to increase an air exposure treatment efficiency sharply, by using oxygen in stead of air effectively and repeatedly for an air exposure vessel, at the time of treating organic waste water by activated sludge method. CONSTITUTION:An air exposure vessel is composed of the cylindrical closed vessel 1 and the partition cylinders 2, 3 provided with passages attaching the lower end on the vessel bottom 1a with the upper ends separated from the ceiling 1b, are equipped in the vessel 1. Also, the partition cylindrical bodies 4, 5 attaching the upper ends on the ceiling 1b and separating the lower end from the bottom 1a and then, the cylinders 2, 3 and the bodies 4, 5 are provided by turns. Each waste water to be treated and O2 gas are introduced from the cental bottom of the vessel 1 from the supply tube 6 and gas distribution tube 10 respectively. The waste water is risen with O2 and air exposure treatment of the waste water is carried out. On this occasion, O2 is made foamy by placing the perforated plate 13 on the way. The waste water is descended in the room B1 and is entered in the air exposure room B1 provided the blowing-in tube 10 at the bottom part and then, the air exposure treatment is carrid out. O2 collected in the upper space of the foregoing air exposure room A1, is sent to the room B1 by the pump 14 and is reused for the above treatment. O2 is used effectively by repeating the above process in plural stages and the air exposure effect is improved.
