Patent JP-H07220974-A (JP)
Title: Electronic part
Inventor: WANO TETSUO
IPC: H01G4/12
Filed: 1994-01-28
Abstract: PURPOSE:To reduce dielectric loss without changing other electrical characteristics by displacing BaO with MgO and adding manganese as a sub- constituent. CONSTITUTION:An electronic part is provided with a dielectric and at least two electrodes provided to the dielectric. A basis of the dielectric of the electronic part is a composition of 0.001<=k<=0.100 in x[(BaO)1--k(MgO)k].yTiO2.zGdO3/2(x+y+=1) and is expressed inside a square region enclosed with a, b, c, d shown in a table I by three-component constituent figure of x, y, z. Manganese is further added by 0.01 to 1.0 parts by weight in MnO2 as a sub-constituent. Thereby, it is possible to acquire an electronic part having high dielectric constant, small dielectric loss, and large dielectric breakdown voltage and insulation resistance. Furthermore, since a crystal grain diameter of the dielectric porcelain is small, the dielectric can be made thin, resulting in a small-sized multilayer ceramic capacitor of large value.

Filed: 1986-01-17
Abstract: PURPOSE:To easily calibrate a flowmeter after plant installation and to control the accuracy of the flowmeter by inputting respective output pulses at the time of count-up operation to a downstream-side and an upstream-side transmitting and receiving circuit. CONSTITUTION:Respective optional set values of the distance L between probes of the flowmeter, the propagation speed C of ultrasonic wave pulses in stationary air, the velocity V of fluid, and the angle theta between the line connecting the probes and the flow direction of the fluid are inputted to a computing element 9 by a constant input setter 8.

Then, pulses of the counter 10 are inputted to the receiving circuit 4 for the downstream-side probe. Further, output pulses from the counter 11 are inputted to the transmitting circuit 3 for the upstream-side probe. Then, the propagation time as the preset values CP1 and CP2 is measured by an ultrasonic wave pulse generating circuit 5 and computed 7. In this case, if there is an error between the velocity V and a logical flow velocity, the zero point of a circuit 7 is adjusted to calibrate the flowmeter.

Title: Kanji (chinese character)-kana (japanese syllabary) converter
Inventor: NOMURA TORIMASA
IPC: G06F3/01
Filed: 1982-01-22
Abstract: PURPOSE:To convert words in the unit of sentences at high speed, by checking independent words and their ending conjugation with dictionaries and detecting words and adjuncts from the remaining words. CONSTITUTION:Japanese sentences comprising Kanji-Kana mixed sentences are stored in a storage device 1. A sentence section circuit 2 takes the inputted sentences into the units of syllabaries by using parts of changes in Kana and Kanji. Words are picked up from one syllable with a word dictionary 4. Long character trains are taken as candidates of conversion among the words detected with coincidence. An ending conjugation detecting circuit 7 detects the ending conjugation for the Kanas excluding the words being candidates of the sentences based on the grammar provided for the words of the candidates. An adjunct collation circuit 10 searches out adjuncts from the remained character trains. From the result, the Kanji-Kana mixed sentences are converted into Kana sentences of split form to translate easily to braille points.

Filed: 1981-01-26
Abstract: PURPOSE:To obtain a long-life optical information recording element which has high density and large capacity, by forming a low-reflectivity black zone as a  guide one for tracking on a recording medium film, consisting essentially of  chalcogen metal, to desired width and at desired pitch. CONSTITUTION:On a transparent discoidal element base plate 1 made of glass, polyimide resin, etc., a recording medium film 2 consisting of essentially of chalcogen metal, such as Te-N and Te-Se, is formed. Then, the base plate 1 is irradiated with laser light under vacuum to cause a change in phase right before the film 2 is fused, thereby forming black zones 3. The black zones 3 are formed spirally or concentrically at constant intervals and to constant width and used as guide ones for tracking by detecting changes in the quantity of light due to a difference in reflectivity from transparent films 2. Those are formed as a smooth surface without providing guide grooves. The corrosion resistance is improved much more than that of a recording element made of only Te, and the obtained element enables high-sensitivity and low-energy writing.

Title: Contact combustion device
Inventor: UEDA AKIO
IPC: F23G7/06
Filed: 1988-01-19
Abstract: PURPOSE:To improve an efficiency of combustion and enable a stable contact combustion to be carried out by a method wherein a gas flow passage of catalyst block is constructed by at least more than two flow passages with different flow passage sectional area. CONSTITUTION:A gas flow passage of a catalyst block 31 is constructed by at least more than two flow passages 33 and 34 having different flow passage sectional area. The flow passage 34 having a large sectional area has a lower frictional resistance as compared with that of a small flow passage 33, so that a gas flow speed is increased. Since a combustion reaction speed through catalyst is kept constant, a position in the small flow passage showing a maximum temperature is displaced toward an upstream side as compared with the flow passage having a large flow passage sectional area. Accordingly, these flow passages having different flow passage sectional area are combined to form a contact combustion device, thereby a temperature is made smooth and a peak temperature can be decreased, so that any sintering may not occur and a catalyst component is not evaporated and a combustion efficiency can be increased.

At this time, beam not scattered by the blood corpuscle (the zero spectrum of the blood corpuscle) is formed into an image on the focus F of the lens 3. A phase plate 4 for shifting the phase of the zero spectrum of the blood c corpuscle by npi/four cycles to the remaining spectrum is provided to the focus plane. The beam passing the plate 4 is formed into an image at a pinhole 5 and the density of the blood corpuscle image at this time becomes high in proportion to the phase shift of each part of the blood corpuscle. The beam of this blood corpuscle image receives electric conversion by a beam detector 6 and the measurement of the blood corpuscle is performed by a processing apparatus 7.
