Abstract: PROBLEM TO BE SOLVED: To obtain the subject highly dispersible particulate iron oxide aggregated particles by aggregating iron oxide primary particles with a number-average particle size within a specific range through dry process so as to bring the number-average particle size to a specific range and ignition loss to a specific wt.% range. SOLUTION: The readily dispersible particulate iron oxide aggregated particles with a number-average size of 30-300 μm, ignition loss of 0.05-2 wt.% and compression degree of <=40% are obtained by aggregating iron oxide primary particles 0.05-1 μm in number-average size through dry process. Furthermore, the aggregated particles thus obtained are pref. <=40 deg. in angle of repose and >=1 g/cm3 in apparent bulk density. More precisely, the iron oxide aggregated particles are produced through the following process: a 80-95 wt.% equivalent of ground and micronized iron oxide particles are kneaded using a Nauta mixer or the like of closed structure with two kinds of kneading actions at 0-50 deg.C and 10-90% RH followed by charging the mixer with the pest of the feedstock in a time distribution corresponding to the weight ratio and then conducting a further kneading.  The iron oxide aggregated particles thus obtained are suitably used as a raw material for electrostatically copying magnetic toners, carriers for developing electrostatically latent images and black pigments.

IPC: G06F12/04
Filed: 1987-08-17
Abstract: PURPOSE:To improve the information processing speed by using the memories of both plane and pixel constitutions and converting data at a high speed between both memories. CONSTITUTION:The 4-word data obtained by scattering and storing the data on a single noticed picture element are read out of a memory of a plain constitution and stored in the internal registers 1-4. Then said 4-word data are rearranged and stored successively into a memory of a pixel constitution. In other words, the 4-word data of the plane constitution memory are converted into a form where four picture elements consisting of four bits (RGBI) respectively are packed into one word. Thus the data are converted at a high speed between memories of different storing types. Then the information processing speed is improved.

IPC: G01N29/26
Filed: 1988-08-19
Abstract: PURPOSE:To improve the rate of flaw detection of a lattice board by placing two probes so that they make an isosceles triangle together with a probe rotating mechanism. CONSTITUTION:An upper lattice board of an atomic reactor consists of thin plates 20 with cuts being provided, and after inserting a flaw detector into it and fixing it with device fixing mechanisms 1, 2, flaw detection is performed by scanning probes 3, 4 vertically and laterally. The probes 3, 4 are placed so that they make an isosceles triangle together with a rotation center of a probe rotating mechanism 5 and offset so that they protrude from the end of a flaw detecting arm 6. The probes 3, 4 are placed so that their direction is made variable owing to the rotating mechanism 5 and one of the probes protrudes from the end of an arm 6 when the rotating mechanism 5 moves on the arm 6 to be located at the end of the arm 6. This enables approaching limitation to be improved without being adversely affected by a main unit even if an incident angle of the probe is varied.

Abstract: PURPOSE:To obtain a nonlinear equipment whose characteristic is changed over easily by using a signal path where a high pass filter, a buffer amplifier, a limiter and an attenuator are connected in cascade in the order as a signal bypass of a nonlinear emphasis equipment and a negative feedback path of a nonlinear de-emphasis equipment. CONSTITUTION:Assuming the amplification factor of an amplifier 2 as B and the transfer function of a signal path comprising a high pass filter 4, a buffer amplifier 5, a limiter 6 and an attenuator 7 be I(s); the transfer function J(s) of the nonlinear emphasis equipment goes to J(s)=B+I(s), and the transfer function K(s) of the nonlinear de-emphasis equipment goes to K(s)=1/[(1/C)+I (s)], where C is the amplification factor of a feedback amplifier 10. Assuming the amplification factor C as C=1/B, the nonlinear emphasis characteristic and the nonlinear de-emphasis characteristic are completely inverted in characteristics. In selecting the attenuation of an attenuator 7 by the recording time length of a VTR, the nonlinear emphasis and the nonlinear de-emphasis characteristic are switched easily by the recording time length.

IPC: H04L9/34
Filed: 1987-08-18
Abstract: PURPOSE:To maintain a recording and reproducing system subject to encryption with high quality by randomizing a consecutive error of a data after decoding when an error takes place in the cryptographic data by means of a de-interleave means so as to apply error correction. CONSTITUTION:The encryption is applied to a data subjected to interleaving after error correction coding in a cryptographic recording means and de- interleave and error correction decoding is applied to a data reproduced and decoded from an optional recording medium in the cryptographic reproducing means. The consecutive error caused in applying decoding to the cryptographic data including an error at recording and reproduction is diffused by the data rearrangement by the de-interleave means and the data error is corrected. Thus, even in the cryptographic system having a high intensity, the propagation of data error at the reproduction by the decoding means 5 depending on the procedure at decoding is reduced and the recording and reproducing system subjected to encryption is kept with high quality.

Title: Surface treatment for stainless steel products
Inventor: YOSHIDA KAZUO
IPC: C21D6/00
Filed: 1985-09-18
Abstract: PURPOSE:To provide stress corrosion cracking resistance to the surface of a stainless steel product by successively melting the surface of the stainless steel product by a local heating means then gradully cooling the steel product so that a specific ratio of delta ferrite is deposited and formed on the surface thereof. CONSTITUTION:An inert gas 3 such as gaseous Ar is ejected from a gas nozzle 4 to form a gas seal 5; at the same time, voltage is impressed via a conductor 6 to a tungsten electrode 7 to generate an arc 8, by which the surface 9 to be treated of the stainless steel product 2 is locally melted. While a TIG torch 1 is moved, the surface 9 is once melted and is then slowly cooled by air cooling to form a melt-treated layer 10 over the entire surface 9. Some delta ferrite phase is thus formed in the crystal grains and grain boundaries of the austenite structure. The delta ferrite phase is deposited and formed at 8-15% of the melt thickness by adjusting the quantity of the heat input to the torch 1. The propagation and growth of cracks are thereby suppressed and the substantial stress corrosion cracking resistance is provided to the surface 9 of the stainless steel product.
