Title: Method for measuring apparent specific gravity of porous body
Inventor: KASAMA SHUNJI
IPC: G01N9/04
Filed: 1986-05-19
Abstract: PURPOSE:To calculate apparent specific gravity and to measure a void ratio with high accuracy, by packing a porous body by a water impervious film under vacuum so that said film is closely adhered to the outer surface of said porous body before calculating an apparent volume using a buoyancy measuring method. CONSTITUTION:A specimen 1 is weighed after drying and wrapped in a water impervious film 2 to be introduced into the vacuum chamber 3 of a vacuum packing machine and an upper lid 4 is closed to evacuate the vacuum chamber 3 by a vacuum pump 5 and the film is hermetically closed by a seal apparatus 6. By this method, the outer surface of the specimen 1 is closely adhered to the film in a state packed by the film. Next, the packed specimen is again weighed to calculate only the wt. of the film and the volume of the film is calculated. Subsequently, the apparent volume of the specimen 1 is measured by the measurement of the volume of the specimen immersed in water and the apparent specific gravity thereof is calculated from the measured values. By this method, a void ratio can be measured with high accuracy even with respect to a large diameter void without wetting the specimen with water.

Inventor: TAMURA YASUKI
IPC: F02D41/14
Filed: 1989-05-09
Abstract: PURPOSE:To facilitate air-fuel ratio control by correcting the output from an oxygen detector means according to the concentration of the nitrogen oxides in exhaust gases and making feedback of air-fuel ratio to a specified value according to the corrected value, to enable the increase in exhaust gas characteristic. CONSTITUTION:An electronic control unit 20 calculates a deviation between the output from a sensor 17 and a reference value, the integrated value of the output from an O2 sensor 17 by the use of a fuel injection ratio feedback gain, and the valve opening time of a fuel injection nozzle 8. A driving signal according to the calculated valve opening time is output into the fuel injection nozzle 8 for a cylinder into which fuel is to be injected, to open the valve and to supply the amount of fuel corresponding to the valve opening time into the cylinder. By this, the output from the O2 sensor 17 is corrected according to the amount of NOx to make feedback of air fuel ratio correctly to a theoretical air fuel ratio irrespective of the operating condition of each engine E. Thus, CO, NOx, etc., can be purified simultaneously by a catalyst converter rhodium 9 at the maximum purification efficiency.

Title: Method and device for controlling boundary layer
Inventor: SHIRAISHI SUNAO
IPC: F15D1/06
Filed: 1980-08-20
Abstract: PURPOSE: To prevent separation from occurring because the flow of fluid along a wall surface changes the proceeding direction along the wall surface, by providing a locally accelerating protrusion at the separation point on an inside boundary wall.  
     CONSTITUTION: A locally accelerating protrusion 3, whose outline is smooth and whose upstream part as to the direction of flow of fluid projects sharply to the flow, is provided on at a separation point on an inside boundary wall 2. At a point II of the distribution of velocity of the fluid flow in the presence of the protrusion 3, the fluid flow near the wall 2 is sharply accelerated in a short section by the protrusion 3 so that the velocity u 1  near the protrusion 3 is especially heightened. An effect similar to what is called Coanda effect can be produced by changing the direction of the flow after especially increasing the momentum of the portion with the velocity u 1 . For that reason, the direction of the flow can be changed while holding the pressure loss down and preventing separation, without disturbing the flow and using a separate motive power source.

Abstract: PURPOSE:To protect the circuit from the excessive input voltage without fail, without regard to the interior connecting state of the input and output terminals, by providing the current outgoing path of a protecting circuit against the excessive voltage at the input terminal on a power supply line, which is different from a grounding line. CONSTITUTION:A semiconductor integrated circuit is constituted by a power supply line 22, a grounding line 23, an MOSFET 27 which receives an input signal from a terminal 25, another MOSFET 29, and the like.

IPC: C21D9/00
Filed: 1979-09-10
Abstract: PURPOSE:To cool steel slab efficiently without causing strain in the slab in cooling the steel slab, by pouring water to the slab piled in a water tank to a level under the upper surface of the upper-most slab, and by immersing the slab into water completely after it is kept for a prescribed time. CONSTITUTION:Plural steel slabs 4 are piled on the laid floor 2 in a water tank 1. Then water is poured into the water tank 1 to a water level 3 3/8-5/8 the thickness (t) of the slab lower than the upper surface of the uppermost layer slab 4a. The slabs are kept at the state for 25-45min, so that a cooling zone 5 is formed around the slab 4a and its elasticity is increased because the water around the uppermost slab 4a boils and cools the circumference of the slab 4a. At that time, water is poured once again until it overflows thereby immersing the whole salb 4a in the water, however no cooling strain is formed because the uppermost slab 4a has high elastic limit.

Title: Charge transfer device
Inventor: OOKUBO YOSHIO
IPC: H01L29/78
Filed: 1981-07-24
Abstract: PURPOSE:To save electric power for charge transfer by adding an inductance between the clock voltage supply terminal and substrate of a charge transfer device, and thus forming a resonating circuit. CONSTITUTION:Parallel resonance is caused at a charge transfer frequency between an externally added inductance L, and total electrostatic capacitance C1 to a lumped parameter substrate of the 1st group of transfer clock gates. A V2 which is the sum of the electrostatic capacitance C1 to the substrates of gate groups 7, 8- belonging to a clock phi1 and electrostatic capacitance Cx by overlaps of gate groups 5, 6- belonging to the V2 is a substrate potential in terms of alternating current. When those electrostatic capacitances are represented as CS and CX, C1=CS+CX and when the clock frequency of charge transfer is fC, (2 fC)<2>L(CS+CX) 1 is obtained as the condition of the parallel resonance. Thus, the loss of electric power required for the charge transfer is reduced.
