Title: Spark plug for internal-combustion engine
Inventor: MATSUBARA YOSHIHIRO
IPC: H01T13/52
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a spark plug for internal combustion engine having superior durability. SOLUTION: A thickness tp of an insulator at the forefront of a leg part 24 of insulator is made less than 1.0 mm, and a discharge voltage is impressed in such a condition that the center electrode 12 is made positive in polarity. Thereby the center electrode 12 is charged positively while the leg part 24 is charged negatively, so that negatively charged particles generated from the end 12g of the center electrode 12d receive electrostatic repelling effect from that end face 24f of the leg part 24 on the side with the firing part and advance via a discharge path S, detouring the forefront face 24f so as to reach the top 16c of the firing surface 16a. This allows decreasing of channeling of the end face 24f on the firing part side due to spark discharge.

Title: Burning prevention device of printer printing head
Inventor: MATSUMOTO HISAYOSHI
IPC: B41J2/30
Filed: 1991-03-26
Abstract: PURPOSE:To prevent a printing head coil from being burnt by enabling interpretation of whether a driver operates normally or abnormally immediately after a power supply is turned ON to a printer, when the driver is shortcircuited. CONSTITUTION:MPU 1 is activated before a power supply for the drive of a head pin of a printing head is turned ON so that the head pin is ready to be driven. Under this state, MPU 1 turns the power supply ON for a short time and then turns it OFF, and at the same time, enters the potential of the power supply 5 using a voltage monitor 6, then records the potential data. Further, MPU 1 enters the potential of the power supply 5 using the monitor 6 after the lapse of a certain time and compares this potential with a previously entered and stored potential. In addition, MPU 1 interprets whether a driver 3 operates normally or abnormally based on this difference value, and makes the power supply 5 inoperative so that it is not turned ON, if the driver is abnormal. Subsequently, if the driver 3 is shortcircuited, the coil of a solenoid 4 is not energized continuously, unless the power supply 5 is turned ON. Thus the coil can be prevented from being burnt.

IPC: C01B33/023
Filed: 1980-06-24
Abstract: PURPOSE: To prepare high purity silicon with simple procedures, economically, by melting a mixture of an alkali metal silicofluoride and metallic Al at a temperature above a specific temperature and below the eutectic point of Si and Al, and then removing the unreacted material and by-products.  
     CONSTITUTION: 3 Moles of an alkali silicofluoride (e.g. Na 2 SiF 6 ) is mixed with 2W6mol of metallic Al, and the mixture is molten at a temperature above 400°C  and below the eutective point of Si and Al (575°C). The melting is pref. carried out under reduced pressure or in an inert gas atmosphere (e.g. Ar) to prevent the oxidation of Al and Si. When AlF 3  is absent in the product, Si can be separated only by easily dissolving the alkali fluoride and the fluoroaluminic acid salt with an acid or a salt solution. When AlF 3  is present in the product, high purity Si can be recovered by treating the product with an acid or a salt solution, and heating the residue at or above the sublimation temperature of AlF 3  (1,200°C) to effect the sublimation of AlF 3 .

Title: High-pass filter controller
Inventor: WASHISU KOICHI
IPC: G01H11/00
Filed: 1986-04-14
Abstract: PURPOSE:To shorten an initial unstable period at the time of the start of input by providing an R1C1 series circuit for removing a bias output, an R2C2 parallel circuit which removes noises and also determined an operational amplification degree, and a high-pass filter, and combining the high-pass filter with a changeover switch means. CONSTITUTION:When a switch knob 25 is pressed in as shown by an arrow 32, switch states 39 and 40 are both on for an extremely short initial time and a signal from an input terminal 11 is inputted to both resistances 91 and 93 at this time. Consequently, a time tau up to the stabilization of the high-pass filter 21 is proportional to the product of the resistance 91 and a capacitor 101, so the resistance value of the series R1C1 circuit becomes temporarily small because the resistance 93 is connected in parallel. The time constant of this circuit, therefore, decreases below the initial value temporarily and the time up to the stabilization is short. For example, when the resistance 91 is set to 3 MOMEGA, the capacitor 101 is set to 1 muF, and the resistance is set to 100 kOMEGA, the time up to the stabilization of the high-pass filter 21 is about 0.1 second.
