Title: Monolithic refractory containing aluminum silicon carbide
Inventor: YAMAGUCHI AKIRA
IPC: C04B35/66
Filed: 1994-12-15
Abstract: PURPOSE: To densify an applied body, to prevent an oxidation of a material liable to oxidize to prevent a slug penetration and to improve corrosion resistance by incorporating a specified amount of aluminum silicon carbide in a monolithic refractory. CONSTITUTION: 0.5-17wt.% aluminum silicon carbide is incorporated in the monolithic refractory consisting of alumina, magnesia, silicon carbide, etc. In this way, this material can safely be used in the monolithic refractory using water because this material does not react with the water different from aluminum metal and aluminum carbide. Moreover, when the aluminum silicon carbide added in the monolithic refractory is brought into contact with a gaseous carbon monoxide, aluminum is gasified and volatilizes and the silicon carbide and the carbon are left, and since the residual silicon carbide is allowed to react with the gaseous carbon monoxide to generate gaseous SiO2 and carbon, the aluminum silicon carbide exhibits excellent action preventing an oxidation of the carbon.

Filed: 1988-12-28
Abstract: PURPOSE:To simplify the attachment of a speedometer and to prevent the influence by a noise by constituting the speedometer of a magnet attached to a wheel, a transmitting part and a receiving part. CONSTITUTION:By a magnet (m) for rotating together with a wheel, whenever a magnetic flux intersects a lead switch l attached onto a front fork of a transmitting part I, its contact is closed. Subsequently, a pulse generated in this case becomes a trigger and a monostable multivibrator circuit 1 operates, and generates a pulse of prescribed width. This pulse is brought to high frequency modulation, and by this frequency, an infrared LED D1 is lighted. Infrared rays from the LED D1 are received by a light receiving unit III in a photodetecting part II, and pulses of the same number as that of receiving signals are given to a primary side of a photocoupler 6. A secondary side of the photocoupler 6 is connected to a pulse input circuit of the speedometer 7. Also, an output of a counter 5 and a circuit of the speed 7 are insulated electrically. In such a way, since pulses of the number being equal to the speed of revolution of the wheel are given, the speedometer 7 displays correctly a running distance, a running speed, etc. Also, a wireless speedometer can be obtained.

Title: Control device for power take out clutch of tractor
Inventor: DOI YOSHINORI
IPC: B60K25/06
Filed: 1987-12-28
Abstract: PURPOSE:To reduce a slip ratio by providing a control device which makes a clutch engaging pressure full pressure when a power take-out shaft is in a rotating condition and which makes the engaging pressure full pressure by rotation after keeping the rotation under a pressure reduced condition for a certain time at the time of a stopped condition, on a power take-out clutch. CONSTITUTION:In a clutch control device 3, when a power take-out switch 29 is turned on and as the rotation of a power take-out shaft 1 is detected by a rotation sensor 28, a pressure control valve 27 is switched over to output the clutch engaging pressure of a power take-out clutch 2 under full pressure immediately engaging the clutch 2. When it is detected that the power take-out shaft 1 is already in a rotation stopping condition, the clutch 2 is engaged under a clutch engaging pressure which is lower than the full pressure and, at this time, as the power take-out shaft 1 is rotated, after keeping the rotation for a certain time, the clutch engaging pressure is made full pressure to engage the clutch 2. Hence, the control of clutch engagement can be accurately carried out, further enabling efficient power transmission with less clutch slippage.
