IPC: G01N27/333
Filed: 1980-11-20
Abstract: PURPOSE:To improve durability and stability, by a method wherein a compound, having a sterilizing power or a propagation-proofing and development-proofing action against a microorganism, is contained in a forming member of an ion selective electrode. CONSTITUTION:An electrode body 1, which has an opening and is divided into two chambers, is formed of a polyvinyl chloride. For example, a chlorine ion selective film 2 is placed at an open end, and the partition chamber so formed with the film 2 is filled with a conductive material 3 to insert a reference electrode 5, made of silver-silver chloride, through a small aperture in a partition 4. A given amount of a compound, e.g., myristyl-trimethylammoniumchloride, cetyltrimethylammoniumbromide or other surface active agents, not interrupting an ion selection but having a sterilizing power or a propagation-proofing and development-proofing action against a microorganism, is added to either of a body 1 of the ion selective electrode so formed, the conductive material 3, and the ion selective film 2.

It is enough to form the chromium oxide film as the oxidized film 13 to the thickness to control the growth of crystals of the base film 14 and is in about several nm range. Immediately after the oxidized film 13 is formed, the substrate is heated at about 250 deg.C in a heating room, and then a Cr-15Ti base film 14 of about 20nm thickness, Co-18Cr-SPt magnetic film 15 of about 20nm thickness and a carbon protective film 16 of about 15nm thickness are formed by DC magnetron sputtering method.  Thereby, the obtd. medium has high coercive force and high coercivity squareness ratio and decreases the medium noise.

Abstract: PURPOSE:To make the interruption of a voice signal during the reception of an electronic tuner tolerable by letting a phase locked frequency synthesizer converge as quickly as possible when broadcasting electric field intensity is checked, in a frequency modulated ratio receiver. CONSTITUTION:When the reception state of a radio broadcast at a frequency f0 is continued for about 5 seconds, a mute circuit 10 is interrupted at time t1, a frequency division ratio setting signal responding to a frequency f1 to be received is supplied by changing the circuit to a frequency divider circuit 21 at the time t2 and thereafter, and at the same time, a common contact 35 of a changeover switch 32 is switched from an individual contact 33 to an individual contact 34. From the contact 35, a voltage is supplied to a voltage controlled oscillation circuit 24, and when the period from the time t2 to the time t3, for example, 0.5ms passes, the voltage imparted to a circuit 24 is changed to a voltage which is equal to the voltage responding to the frequency f1 to be received. Next, when the contact 35 is switched to the individual contact 33, whether the time W2 from the time t3 to t4 passed is judged. If the time is judged to have passed, the locking of a phase locked frequency synthesizer 6 is converged in short time W4.

Title: Discharge lamp lighting device
Inventor: NAGAI SATOSHI
IPC: H02M7/5387
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To make a compact and inexpensive coil usable to reduce the cost by delivering the power so as to fill up the valley of voltage of a rectifying circuit output, and storing and releasing a part of the power to be imparted to a discharge lamp in a smoothing capacitor. SOLUTION: A coil 10 is formed of first and second coils 10a, 10b. An independently operating first resonance circuit is formed by the first coil 10a and a first capacitor 12 connected in parallel to a discharge lamp 11 to limit the current of the discharge lamp 11. An independently operating second resonance circuit is formed by the second coil 10b and a second capacitor 13. When a first transistor 4 is ON by the drive signal of an oscillating circuit 8, a third capacitor 4 is charged from a rectifying circuit 3 through the first transistor 4 when the resonance voltage generated in the second resonance circuit is zero.  Since the charge current performs the power delivery of carrying a high frequency current corresponding to the voltage of a commercial power source 1 and filling up the valley of the output voltage of the rectifying circuit 3, the input waveform of the high frequency current becomes close to the input voltage waveform, and the generation of power source harmonic wave can be reduced at a high power rate.

Title: Production of formed material of gelatinous thin film having plasticity
Inventor: TOKUMOTO JUNICHI
IPC: C04B35/622
Filed: 1988-06-30
Abstract: PURPOSE:To improve the plasticity of a molded article by hydrolyzing a metal alkoxide solution, adjusting the pH of the sol to a specific level and lowering and then raising the pH with an acid and an alkali to form a formed article. CONSTITUTION:A solution of a metal alkoxide is hydrolyzed with an acid to form a sol having a pH of 2-3. The pH of the sol is lowered to about 1.2-1.6 with nitric acid, etc., and then adjusted to 1.5-3.5 with an alkali. The sol of the above state is dried and cast to obtain a formed material of gelatinous thin film. Since the formed material is produced by the lowering and raising of the pH of the sol without using any organic binder, the processability of the formed material can be improved to prevent the damage and deformation of the material in processing. The plasticity of the formed article can be improved by this process.
