Title: Treatment of organic sewage and treating device
Inventor: KATAOKA KATSUYUKI
IPC: C02F3/12
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To greatly reduce an excessive sludge quantity and prevent a occurrence of bulking and scum by drawing out at least a portion of a sedimentation component in a sedimentation tank as returning sludge, bringing the returned sludge into contact with ozone-containing gas, while the returning flow rate is periodically increased and decreased, and then returning it to an aeration tank. SOLUTION: Raw water 2 being organic sewage is biologically treated with an aeration tank 1, and a produced activated sludge slurry 3 is subjected to a solid-liquid separation with the sedimentation tank 4, and a separated liquid component is taken out as treated water 5. At that time, a portion of the biological sludge 6 is drawn out from the sedimentation tank 4 to be treated with ozone at the ozone contact part 7 and then is returned to the aeration tank 1.  The ozone-containing gas 12 from the ozone producer 11 is brought into contact with the returned sludge 9 at the ozone contact part 7, and a high polymer of the outside body of bacterium in the returned sludge 9 and an constitutional element of a cell wall are decomposed and become lower molecules to produce BOD and this is decomposed to gaseous carbon dioxide and water with microorganisms in the aeration tank 1, thus excessive sludge quantity is reduced.

Each arm  tip is set at the center of a chuck 10 in the direction opposite to that of the displacement of a sample 21, namely, reversely and slantly in parallel. The surface plates 22'  and 22' of the sample are supported with the upper end support shafts 14', 16', 18' and  20' in such a manner to rotate by an angle of alpha. A reinforcing wall 24 is provided on  the back of the chuck 10 to support the arms 12' and 12'' at a fixed space thereby  maintaining the lower end shafts 14'', 16'', 18'' and 20'' of each arm tip at a fixed space.  The upper ends 14', 16', 18' and 20' are lowered as the sample is pulled down and the  arm tip is displaced horizontally. This increasing chucking pressure evenly on the surface with respect to the sample thereby checking the interruption of the chucking.

Title: Solid state laser oscillator
Inventor: ISHIKAWA KEN
IPC: H01S3/093
Filed: 1986-01-29
Abstract: PURPOSE:To provide a slab shaped solid state laser, whose directivity is slightly de creased but oscillating efficiency is not decreased, by the constitution wherein both end surfaces facing optical resonator are made to be optical planes, said surfaces face exciting lamps and are intersected with both side surfaces at right angles, and a laser medium is made to be a rectangular parallelopiped. CONSTITUTION:The upper and lower surfaces and both end surfaces in the longitudinal direction of a laser material 10 are formed in optical flat planes. Reflection preventing films are applied on these surfaces. Straight tube type exciting lamps 11a and 11b are provided in parallel at one of the upper and lower surfaces. The exciting lamps for the laser material are separated with a light transmitting partitioning plate 12. The laser material 10 is optically excited in the broad planar direction. Laser light L is emitted from one reflecting mirror 20 through resonating actions of the reflecting mirrors 20 and 21. During the resonating process, a zigzag light path and a straight light path are formed in the laser material 10. Since both end surfaces are vertical, diverging light in one direction is formed. The light is made to be parallel light through a collimate lens 22 and the directivity is corrected. Since the laser material 10 acts as a lightguide, optical quality is not deteriorated even if the laser material is long. Thus high output power is obtained.

Title: Heating state detection device of engine
Inventor: MATSUSHITA TOMOHIKO
IPC: F02D45/00
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To properly detect a heating state of an engine. SOLUTION: A water temperature sensor 48 is installed on a cylinder block 28 of a diesel engine 1, and temperature of cooling water in a block side cooling water passage 34a is detected by the sensor 48. A CPU of an electronic control device (ECU) 60 judges whether cooling water temperature detected by the water temperature sensor 48 becomes higher than threshold value temperature or not, and it decreases fuel injection quantity in the case when the cooling water temperature is higher than the threshold value temperature. The CPU renews the threshold value temperature by reading the threshold value temperature corresponding to the lowest temperature from an ROM of the ECU 60 when the cooling water temperature is changed from dropping over to rising and becomes the minimum temperature.  The threshold value temperature stored in the ROM is set at the lower temperature, the lower the minimum temperature is.

Abstract: PURPOSE:To attempt long time operation of a waste changing facilities to load charged waste on a barge on the water surface by reusing a waste charging stage at another work site after it finishes the work at one work site by way of supporting the waste charging stage of the waste transshipping facilities on a floating body. CONSTITUTION:It is possible to reuse waste transit facilities by towing it integrally with auxiliary various mechanical facilities 10 without disassembling it and moving it to another work site after duty at one work site is finished, as its charging stage 2 is supported by floating bodies 12a, 12b. Additionally, in this case, it is required to prepare a circumferential condition possible to tow the stage 2 from the work site where the work is finished to another work site. If the waste transshipping facilities are devised to be reused at another work site after the work is finished at one work site in this way, one set of auxiliary facilities such as the mechanical facilities 10 can be operated for a long period of time by reusing it. Additionally, as the stage has a floating body structure, a draft adjustment can be made in accordance with the land shape and the amount of construction work can be significantly reduced in comparison with a new construction.

Abstract: PURPOSE:To prevent the underflowing of picture signal data at an output buffer by monitoring a data quantity in an input buffer and applying a suitable quantity of the filling bit to the picture signal data at the time of a constant quantity or below. CONSTITUTION:A processing part 2 always monitors the quantity of data in an input buffer 1 and issues a receiving request to the high order when the quantity comes to be b0 or below.
