Title: Method for discriminating quality of zinc oxide
Inventor: WATANABE MITSUYOSHI
IPC: G01N23/223
Filed: 1989-08-04
Abstract: PURPOSE:To discriminate quality of zinc oxide and to estimate fraction defective of ZnO element utilized as a product by separating impurities contained in zinc oxide as residue and analyzing the characteristics of the impurities. CONSTITUTION:In a first stage, a prescribed soln. is produced by dissolving zinc oxide contg. impurities by liquid incorporating at least one kind of acid, e.g. hydrochloric acid. In a second stage, this soln. is filtered by utilizing a proper filtration film e.g. filter paper. Insoluble material is separated as residue on the filtration film. In a third stage, quality of zinc oxide contg. the impurities is discriminated from the prescribed characteristics of residue e.g. the characteristics of X-ray fluorescence analysis. For example, fraction deflective of ZnO element which is produced from zinc oxide contg. the impurities can be estimated by previously obtaining both the prescribed characteristics of residue and the characteristics of the fraction deflective when ZnO element being a product is produced from zinc oxide contg. the impurities.

Abstract: PURPOSE:To remove dew without operating a refrigerator by providing by-pass tubes which connect the entrance valve upstream side of a 1st dehumidifier connected in series to the exit valve upstream side of a final dehumidifier and also connect the entrance valve downstream side to the exit downstream side. CONSTITUTION:Off gas which is cooled by an after-cooler on the upstream side of a dehumidifier 8 with saturated air enters a cooling part from the lower nozzle of a dehumidifier 8A after cooling operation and contributes to remove dew. Sensible heat is absorbed as a result of the dew removal to lower the temperature, so the temperature is about 5-7 deg.C at the entrance of the dehumidifier 8B. Consequently, the heat quantity removed by the dehumidifier 8B is small and precooling operation that a conventional dehumidifier 8B performs before cooling operation is unnecessary. Further, when the dehumidifier 8A is put in operation, the valve 47 of a 1st by-pass tube is open, and the exit valve 45 of the dehumidifier 8C is open; and the valve 49 of a 2nd by-pass tube is open and the entrance valve 42 of the dehumidifier 8A is closed, so that the off gas flow. At this time, the off gas enters the cooling part from the exit side of the dehumidifier 8B to remove the dew and enters the cooling part from the exit side of the dehumidifier 8A, so that cooling operation is carried out.

SOLUTION: A synthetic resin substrate 10 has a cavity section 11 for mounting a semiconductor integrated circuit element at its central part, and a step section 14 on the outer peripheral end face 13 side of the main surface 12 opposite to a flat surface 16 of the substrate 10, on which the cavity section 11 is formed. The step section 14 has a minute flat section 141 and a relatively large slope 142 formed from the outer peripheral end face 13 side, and minute flat sections 143 and 145 and slopes 144 and 146 formed in the boundary section between the slope 142 and main surface 12. The boundary sections 147 between the three flat sections and three slopes are all formed with smooth curved surfaces, having radii of curvature in the range of 0.02-0.2 mm.  Therefore, even if the substrate 10 comes into collision with other members, the occurrence of the chipping and cracking of the substrate 10 can be prevented, because the step section 14 can absorb shocks.

Abstract: PURPOSE:To obtain the stability of a resistance value with the elapse of time and excellent initual rumbling characteristics by forming a gas sensitive layer by adding metal oxide with a large specific surface area having a noble metal catalyst supported thereon to a metal oxide semiconductor. CONSTITUTION:A first oxide combustion layer 3A perfectly covers a substrate 1 and the gas sensitive layer 4 formed on an electrode 2 and a heater 8 is formed on the other main surface of the substrate 1 and an electrode 2A.

Title: Production of liquid jet recording head
Inventor: MIYAGAWA MASASHI
IPC: B41J2/16
Filed: 1992-07-30
Abstract: PURPOSE:To obtain a liquid jet recording head of low cost, high accuracy, high reliability, and high resolution by a method wherein after a pattern of a common liquid chamber is made out of a photosensitive material, a top plate member is laminated. CONSTITUTION:A pattern of ink flow paths is made on a substrate 1 out of a soluble resin. Such a resin pattern may be formed using a screen printing means or the like, but in many cases it is preferable for an accuracy that the resin pattern is made out of a photosensitive resin by a photolithography. Since a top plate member 7 is laminated after a liquid chamber is formed, a low-cost material or a processed material can be selected without limiting the material (light transmittance, refractive index, and the like) and shape of the top plate member 7, in comparison with a means for forming the pattern of the ink liquid chamber by light exposure after the lamination of the top plate member 7.

IPC: G11B20/18
Filed: 1983-10-31
Abstract: PURPOSE:To prevent mis-recognition for a data as an erroneous data in case the synchronism between a reading frequency and the recording data are incomplete by inhibiting the operation of a defective discriminating means before prescribed time required for adjustment of the reading frequency. CONSTITUTION:When the operation of a mark detection circuit is delayed for example, while a format on a stripe is normal, its output signal rises through the burst detection of a burst detection circuit 1, then a command of high gain operation is outputted from a reproducing data control circuit 6 to a VFO circuit 2 at that point of time, an inhibiting circuit 8 is activated and a de-mark pattern recognition circuit 7 is inhibited for the operation. Thus, if the reading frequency and the recorded data are not completely synchronized, the recorded data is prevented from being mis-recognized as a defective discrimination pattern.

Filed: 1986-08-29
Abstract: PURPOSE:To provide the same gain as that of a conventional circuit and to increase the input impedance by combining an input stage receiving directly a differential input and two current mirror circuits so as to form the titled circuit. CONSTITUTION:Differential inputs V1, V2 from input terminals 11, 12 are fed directly to each gate of FETs T3, T4. The input stage FETs T3, T4 are connected respectively to current mirror circuits comprising FETs T1, T5 and FETs T2, T6 respectively. Then the differential outputs V01, V02 are extracted from between the two current mirror circuits. Let the differential input be (V1-V2) and the gain be R2/R1, then the dfferential output (V01-V02) is expressed as (R2/R1)(V1-V2) and the gain R2/R1 is the same as that of a conventional circuit. Since the differential input is directly fed to the input stage FET, the input impedance is increased.
