Title: Exhaust particulate collecting trap regeneration control device for internal combustion engine
Inventor: AKIYAMA KAZUNARI
IPC: F02B37/10
Filed: 1995-05-30
Abstract: PURPOSE: To detect the plugging of the filter of a trap device to regenerate the filter by providing an exhaust pressure boosting means for boosting exhaust pressure by the motor operation of a motor-generator in the low rotation area of an internal combustion engine. CONSTITUTION: In order to determine the regeneration timing of the filter 3a of an exhaust particulate collecting trap 3, the pressure ratio of pressure sensors 5, 6 is obtained, and in the case of the specified value or more, regenerating action is executed. In the case of the rotation of an internal combustion engine 1 being lower than the specified value, a signal for switching a motor-generator 2c to an exhaust pressure measuring mode is sent to a motor-generator control device 10. Upon receiving this signal, the motor-generator control device 10 switches the motor-generator 2c to a motor operating mode and outputs a control signal for the specified motor operation to the motor-generator 2c. The specified motor operation means the operation of the motor-generator 2c under operating conditions to obtain such exhaust pressure as to stabilize the signals of the pressure sensors.  Stable pressure detection can therefore be performed even in a low rotation area.

Filed: 1982-07-28
Abstract: PURPOSE:To release treated waste water with good quality in a stage for treating the waste water by a biological memberene method, by aerating excessively the waste water temporarily from an ordinary aeration state to remove forcibly the biological membrane periodically from a contact base material. CONSTITUTION:Waste water 1 to be treated is introduced into a treatment tank 2, where the water is subjected to a biological membrane treatment. The treated water 3 is fed to a settling tank 4, where the water is subjected to a solid- liquid sepn. The separated water is released as release water 8. Plural net-like contact base materials 5a-5d are packed in the tank 2, and when the qualtity of the water 8 begins to deteriorate, an excess amt. of air is ejected simultaneously from all the air diffusion pipe 7 groups of an air diffuser 6 attached to the materials 5a-5d to aerate the materials. The biological membrane of the decreased degree of activity sticking to the net-like contact base material are forcibly removed and are made to the fresh biological membrane having a high degree of activity to activate the treatment, whereby the quality of the water released from a settling tank 4 is improved.

Title: Facsimile equipment
Inventor: YOSHIDA TAKEHIRO
IPC: H04N1/00
Filed: 1993-05-10
Abstract: PURPOSE:To improve energy efficiency and to attain cost reduction by detecting a used current value and changing the specification of a facsimile equipment based on the detected used current value. CONSTITUTION:A power source is designed by a current value which is smaller than that of the specification of the power source when a full specification operates and the basic specification of a facsimile is realized at first by the power source for which cost reduction is performed. A specification is added to the basic specification based on both the information on the current value which is being used at present and temperature information. Concretely, a control circuit 46 controls a receiving/recording operation and a reading/ transmission operation independently, judges the possibility of the storage to a reading/memory based on the present temperature information and used current value information when the storage to the reading/memory is selected during the receiving/recording operation and determines the reading speed. Namely, the lower the temperature information is and the smaller the used current value is, the faster the reading is performed. Thus, the operation of the full specification becomes possible with inexpensive power supply in most cases.

Title: Printing apparatus for thermal stencil processing
Inventor: YAMAGUCHI HIDEYUKI
IPC: B41L13/04
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To obtain printed matter having a good imaging property and no set-off by providing a pair of rollers for pressing a thermal stencil original paper in its thickness direction at the prior stage of performing stencil image formation in a thermal processing part. SOLUTION: A pair of pressing rollers 16, 17 capable of pressing thermal stencil original paper 2a in the thickness direction are provided at the prior stage of a thermal head 3. This compresses the thermal stencil original paper 2a in the thickness direction. By pressing the thermal stencil original paper prior to image formation while being passed through two rollers, the density of the porous layer can be heightened without increasing the number of adhesive points between the thermoplastic resin film and the porous layer and set-off can be reduced as maintaining its thermally punching property. Also, the pression roller 16 to be in contact with the porous layer is allowed to be heated among the pair of rollers for pressing the thermal stencil original paper 2a in the thickness direction.  Furthermore, since the pair of rollers 16, 17 have a size to press only an image depicting area, paper feeding can be facilitated by thickened parts left at its both ends.

Filed: 1979-10-16
Abstract: PURPOSE: To improve a water turbine efficiency, by a method wherein a flow-in path is bent in the same direction as that of a casing spiral.  
     CONSTITUTION: A preliminary whirl flow path 6 having a spiral angle ϕO is positioned at an upstream side outside a point A where an outer shell 1a of a casing spiral terminal section crosses a stay vane 3 row. A centrifugal force excercises on a flow from the upper stream at the preliminary whirl flow path 6 and said flow changes from an uniform flow 9 to a free spiral type speed distribution 10 on a flow cross section surface, whereby a well-rectified flow is obtained at a stay vane inlet and over the whole circumference. That is, after the free spiral flow speed distribution is realized at the preliminary whirl flow path 6, the flow reaches a point A and afterwards, whereby the influence by a secondary flow can be uniformalized in the circumferential direction and accordingly, a peak proper of the secondary flow is not produced. After flow-in water passes through the stay vanes 3, it enters into runner blades 5a through guide vanes to rotate runners 5.

CONSTITUTION:A buffer solution in a relevant tank 1 is continuously fed, using a feed pump 2, into a sampler 3, and a thermostat 6 is charged with a pullulan- contg. sample from the sampler 3, and this sample is brought into contact with an immobilized glucoamylase column 4 to produce glucose from the non-reducing terminal, which is, in turn, reduced or oxidized at glucose-detecting enzymatic electrodes 5 into an electrode-active substance; change in current value is detected by a detector 7, and the resulting signals is transmitted to a single board computer 8 where they are converted to glucose concentration. Using this value, the pullulan's molecular weight for the sample is calculated from the relationship between the known molecular weight of pullulan measured in advance and the quantity of the glucose produced, thus determining the objective molecular weight of the pullulan.
