IPC: G01J3/427
Filed: 1979-03-02
Abstract: PURPOSE: To improve the stability of diode-feedback system by supplying the absolute value of feedback voltage to the voltage producing circuit in the interval of zero-light signals.  
     CONSTITUTION: Reflected light 34 from a sector mirror, transmitting light 35 and light cut state are input to CPU and processed therein as a reference light signal R, a sample light signal S and a zero-light signal Z, respectively. These signals R and S are directly related to the feedback ratio and suffers great influence by its fluctuation, while the signal Z is not directly related to the feedback ratio. In the measurement of two light flux modes, after judging if the present sampling data belongs to R, S or Z, the maximum data is stored as the larger R or S when the sampling data corresponds to R or S, and at the interval of Z, the previously stored maximum data is compared with the reference value and then the formula of (gain)×[(reference value)-(maximum data)] is calculated as feedback ratio. By so doing, it becomes possible to constitute more stable control system.

Abstract: PURPOSE:To remove troubles in hot rolling and to carry out slab heating without deteriorating electromagnetic properties by carrying out heating at specific temp. rise rate after preheating and regulating the upper limit of slab heating temp. to the solidus temp. or below at the time of soaking treatment prior to rolling. CONSTITUTION:A continuously cast slab of silicon containing steel is preheated at 1000-1250 deg.C for >=30min in a combustion gas heating furnace. Subsequently, this slab is introduced into an induction heating furnace and heated at <=150 deg.C/hr average temp. rise rate until average slab temp. reaches 1300 deg.C, and also the maximum temp. in the slab is regulated to the solidus temp. or below to prevent the coarsening of crystalline grains. Then, the slab is heated at >=1380 deg.C for >=5min to undergo soaking treatment. Successively, the slab is hot-rolled and cold-rolled while process-annealed between the cold rolling stages so as to be formed to the final sheet thickness, to which decarburizing and primary recrystallization annealing and final finish annealing are applied. By this method, a grain-oriented silicon steel sheet excellent in magnetic properties can stably be produced.

Title: Scavenging device for two-cycle internal combustion engine
Inventor: SHIRAI KATSUHIKO
IPC: F02B75/02
Filed: 1994-02-23
Abstract: PURPOSE:To secure the scavenging near a spark plug to prevent the lowering of trapping efficiency, and to improve the ignitability and the combustibility by fully closing one of scavenging ports or partially opening it to reduce a blow-up angle in an operation area at a high scavenging ratio. CONSTITUTION:In an operation area at a low scavenging ratio such as a low load area, since a control valve 10 is operated to open a scavenging port 7 and the charging is blown into a cylinder 1 from the scavenging port 7 in the arrow A direction, scavenging near a spark pug 3 is secured to improve the trapping efficiency. In an operation area at a high scavenging ratio with the increase of load, the control valve 10 is fully closed to stop the blow-up of the charging from the scavenging port 7, and the quantity of charging passing through toward an exhaust port 4 is reduced. In an operation area at a higher scavenging ratio with the more increase of load, the control valve 10 is operated to partially open the scavenging port 7, and a deflection is performed so that the blow-up angle theta1 of the charging is reduced. A rise in the compressed pressure of a displacement type compressor 5 is thereby prevented to restrict an increase in the power loss.
