Title: Production of foam glass
Inventor: TAKEUCHI TETSUHIKO
IPC: C03B8/02
Filed: 1988-03-31
Abstract: PURPOSE:To obtain various kinds of foam glass with a simple process, by drying a wet gel having the composition of the objective glass, diffusing cations acting as sintering assistant into the surface of the obtained glass precursor before the completion of the sintering of the precursor and sintering the product. CONSTITUTION:A metal alkoxide (e.g., ethyl silicate) or the metal alkoxide and fine particles of a metal oxide are mixed with ethanol, water and ammonia water, stirred and aged at normal temperature. The aged liquid is concentrated under reduced pressure, hydrochloric acid is added to the resultant dispersion of fine silica particles and the mixture is stirred to obtain a hydrolyzed solution. The prepared liquid sol is gelatinized, put into a drying vessel made of e.g., PP and dried to obtain a porous gel. The gel is immersed in a solution containing a cation capable of forming a sintering assistant such as Na<+>, dried and heated e.g., at 1350 deg.C. The objective foam glass containing a large number of closed cells in the glass can be produced by this process.

Title: Power control device for automotive internal-combustion engine
Inventor: TOOMASU RIIEMAN
IPC: F02D45/00
Filed: 1990-03-29
Abstract: PURPOSE: To ensure safe operation by detecting changes in the desired value and actual value of the position of an actuator, determining whether or not an electrical failure has occurred according to the changes, and, if the failure of a device recognized to have experienced an electrical failure before has been eliminated, recovering the function of the device with delay. CONSTITUTION: If the function of an actuator 13 has failed, for example, a throttle valve 11 moves to an idling or closed position. A desired value signal which is issued to a lead wire 18 when an accelerator pedal 21 is operated takes a constant value from time t6 to time t10 and the actual value signal VA of the lead wire 16 of the throttle valve 11 takes a value of VA4 at the time t6 . If the function of the actuator 13 fails at time t7 , the valve 11 moves to the closed position as stated above, and therefore the actual value signal also decreases to VA5 at time t8 . If the function of the actuator 13 has recovered the time t8 , then a microcomputer 18 performs a process so that the valve 11 moves to a corresponding position at time9 with a delay of time.

IPC: H01L23/48
Filed: 1987-04-01
Abstract: PURPOSE:To improve the heat resistance and conductivity of a lead having magnetism by forming a skin by oxygen-free copper and an internal layer by alumina dispersion-reinforced copper and shaping a plurality of core materials made of iron or an iron alloy onto the outer circumferential section of the internal layer. CONSTITUTION:A skin 2 is formed by oxygen-free copper and an internal layer 3 by alumina dispersion-reinforced copper, and a plurality of cores 4 made of iron or an iron alloy are shaped onto the outer circumferential section of the layer 3 at regular intervals. The sectional areas of the iron cores are brought to 0.77-10.3% of overall sectional area, and the number of the iron cores is brought to three or nine. It is because conductivity is lowered when these values surpass upper limits, and magnetism is insufficient when they are less than lower limits. The thickness of the skin 2 is brought to 3.8-15.0% to a wire diameter. Heat resistance is deteriorated when the thickness of the skin 2 exceeds an upper limit, and workability and solderability are degraded when it is less than a lower limit. The quantity of aluminum in the layer 3 is kept within a range of 0.02 wt. % or 0.6 wt. %. Conductivity and workability are lowered when the quantity of aluminum in the layer 3 is brought to an upper limit or more, and heat resistance is insufficient when it is brought to a lower limit or less. Accordingly, the heat resistance and conductivity of a lead having magnetism are improved.
