Title: Manufacture of high purity metallic oxide
Inventor: MIYAZAKI KUNIHIRO
IPC: C01B13/18
Filed: 1981-06-29
Abstract: PURPOSE:To manufacture simply and efficiently fine powder of high purity metallic oxide by thermally decomposing a molten viscous low grade polymer obtd. by thermally polymerizing single or composite metallic alkoxide to form a brittle decomposition product. CONSTITUTION:By thermally polymerizing single metallic alkoxide or composite metallic alkoxide composed of >=2 kinds of metallic alkoxides, the viscosity is increased, and a molten viscous low grade polymer is obtd. The polymer is thermally decomposed. The decomposition product expands remarkably by foaming and is made brittle and very fragile, so it can be reduced to fine powder only by slight crushing. Since the decomposition product is generally amorphous or low crystalline, it is converted into fine powder of crystalline metallic oxide by roasting at a prescribed temp. By this method metallic alkoxide can be purified. Accordingly, fine powder of high purity metallic oxide can be manufactured.

Title: Valve timing regulation device
Inventor: SATO OSAMU
IPC: F01L1/34
Filed: 1998-04-13
Abstract: PROBLEM TO BE SOLVED: To provide a valve timing regulation device capable of securely actuating without deteriorating responsiveness at a normal time in a simple constitution. SOLUTION: A torsion spring 60 energizes a vane rotor 4 on the advancing angle side to a timing pulley 8. Energization force of the torsion spring 60 is an average torque of a cam shaft 1 at the time of idling in high oil temperature or more, and less than twice the average torque. In a normal rotation range of an engine over idling, therefore, the vane rotor 4 can be rotated in an advancing angle direction even when there is no oil pressure, so an exhaust valve can be moved to the foremost advancing angle position. An overlap period in which the exhaust valve and an intake valve are overlapped to open can thus be reduced to such a degree as to be capable of starting the engine at least, so engine startability is improved. By reducing oil flow flowing into each oil pressure chamber formed in a shoe housing 7, phase conversion responsiveness can be improved.

Title: Testing method of cable
Inventor: TSUNODA YOSHIO
IPC: G01R31/02
Filed: 1983-06-06
Abstract: PURPOSE:To facilitate a simultaneous testing of three phases by making the imposed voltage almost equal to the test voltage to shield a high voltage charge section at the final end of a cable on the far end side. CONSTITUTION:The voltage of a power source 7b is made almost equal to the voltage of a power source 7a and current of a cable conductor is measured with a recorder 12 under such an imposed voltage. In this case, the inflow of a leakage current generated at the final end 2a of a cable on the measuring end side to a measuring device can be prevented as was in the past. On the other hand, since the potential of a guard electrode 3b is kept almost equal to that of a cable conductor terminal 21b at the final end 2b of the cable on the far end side, there is no leakage current between the 21b and 3b. The leakage current A flowing into the guard electrode 3b and the leakage current B between the ground and a shield case 4b flows as shown by the dotted line, none to the cable conductor. Thus, no leakage current generated at the final end 2b of the cable on the far end side appears thereby assuring an accurate measurement.
