Title: Production of magnetite grain
Inventor: OMORI MASAHIRO
IPC: C01G49/08
Filed: 1990-03-12
Abstract: PURPOSE:To obtain magnetite grains having high oxidation stability without change of saturated magnetization with the lapse of time by adding an organic substance to a reaction system, heating the mixture at a specific temperature and forming oxidation-resistant organic coating film on the surface of the resultant magnetite grains and subjecting to the magnetite grains to partial oxidation treatment when iron oxide is reduced. CONSTITUTION:When an iron oxide (e.g. gamma-Fe2O3) is reduced with a reducing reaction gas to provide the magnetite grains, an organic substance (e.g. petroleum based oil) is added into the reaction gas or iron oxide. Then the mixture is heated to 300-600 deg.C and an oxidation-resistant organic coating film is formed on the surface of the resultant magnetite grains. Then the magnetite grains on which the organic coating film was formed is subjected to partial oxidation treatment and stabilized by a method, etc., treating grains with air enriched in nitrogen to provide the magnetite grains having excellent oxidation stability. Furthermore, the grains can be stabilized also by forming an inorganic oxide coating film on the organic coating film instead of carrying out partial oxidation treatment.

The roller 7 and roller 9 are pressed by springs to the end face 10 of the slider 3 capable of advancing in the axial direction of the feed screw 3. If these are set at la:lb = a:b and the points GA, GB, CB are in the alignment in the case of zero order light, then the spectroscope having the diffraction grating 4 and that having the diffraction grating 5 become always the same in wavelength even if the feed screw 2 is rotated. If the spectroscopes are let phiA, phiB by using the diffraction gratings 4, 5, la:lb is brought to the relation of the formula (A).

Title: Method for solidifying magnesium carbonate
Inventor: SHIBAZAKI YASUO
IPC: C04B28/00
Filed: 1994-03-31
Abstract: PURPOSE:To solidify MgCO3 or a material consisting essentially of MgCO3 under mild conditions. CONSTITUTION:MgCO3 or a material consisting essentially of MgCO3 is solidified by adding a solubilizing material such as alkali salt, etc., to it or using the solubilizing material as the autoclave treating solution and subjecting the resulting mixture to autoclave reaction under consitions of comparatively low temp. and low pressure. Thus, MgCO3 or a material consisting essentially of MgCO3 is easily and efficiently solidified under mild conditions of comaratively low temp. and low pressure by only treating it through using a conventional device, i.e., an autoclave. Accordingly, the reduction in energy consumption and cost in the MgCO3 solidification technique can be attained.

Title: Alkali primary battery
Inventor: OOHIRA TSUKASA
IPC: H01M4/42
Filed: 1983-04-08
Abstract: PURPOSE:To decrease the danger of environmental nuisance from mercury and obtain a battery not inferior in its characteristic to that using an amalgamated zinc electrode, by using a ternary alloy consisting of zinc, lead, and mercury as the negative electrode active material and adding a soluble indium compound to the electrolyte. CONSTITUTION:A ternary alloy consisting of zinc, lead, and mercury is used as the active material for the negative electrode 5 and a soluble indium compound is added to the alkali electrolyte. For example, the composition of the ternary alloy is 98wt% of zinc, 0.5wt% of lead, and 1.5wt% of mercury, and 3wt% of bridge type polyacrylic sodium is added to the powder of the zinc alloy. In the ternary alloy in which the lead is segregated, the mercury on the surface of the zinc particles can maintain, with such a small amount as 1.5wt%, a high hydrogen overvoltage by virtue of synergistic effect of adsorptive action between the same and the indium ion. As to the amount of indium hydroxide, indium oxide, or the like to be added to the electrolyte, 1g/l or thereabout is sufficient.

Title: Optical recording device
Inventor: TORASAWA KENJI
IPC: G11B7/135
Filed: 1986-03-19
Abstract: PURPOSE:To read accurate address signal not influenced by a recording beam modulated by information to be recorded by utilizing a laser diode means provided with two radiant points of a beam for recording and a beam for erasing and irradiating the beams to a remote track. CONSTITUTION:At the time of recording, reflected light of a beam for erasing is made incident on B1 photosensors 19, 22, and the address signal can be led out from either photosensor. At this time, reflected light of beam for recording B2 is not made incident on the photosensors 29, 22 and accordingly, the accurate address signal can be obtained. Reflected light of the beam for recording B2 modulated by information signals to be recorded is made incident on photosensors 20, 23. However, as the frequency band of a record information signal, a focus error signal and a tracking error signal differ largely, no hindrance occurs in detection of the focus error signal and the tracking error signal.

Abstract: PROBLEM TO BE SOLVED: To make the image forming device display stable image quality performance by preventing scatter of toner upon interrupting a soaring transfer electric field, and lowering of the image definition, a blur or the like. SOLUTION: This device is made possible so as to be formed very thin as compared to a conventional guide member by constituting the guide member 28 for guiding a paper sheet to a transferring nip, in a sheet shape on thin layer coating the sheet shape conductive member 29 by means of insulating resin 61. Thus, the guide member 28 can be arranged nearer to the nip part as compared with the conventional practice. Moreover, by coating the guide member 28 by means of the insulating raisin 61, a leakage of a transfer voltage during the time of transferring, or the transfer current leakage under the high humidity environment can be prevented, therefore the inconvenience such as the transfer fall is made possible to restrain.  Furthermore, by preventing the soaring transfer of the toner, by means of interrupting the soaring transfer electric field on the right front of the nip part by the conductive member 29 of the inside layer, the blurless image formation with high sharpness is made possible.

Abstract: PURPOSE:To discriminate the kind of the paper sheets by optical detection without using a white reference plate by controlling the gain of a photoelectric converting means with the output of the photoelectric converting means corresponding to light reflected on a non-print part of the paper sheets. CONSTITUTION:A 1st sensor 11 detects the presence of the paper sheets with the light from a 1st light source and outputs a paper sheet detection signal. A 2nd sensor 14 converts the quantity of the light reflected on the paper sheets into an analog electric signal and outputs it. A CPU 22 calculates a reference value specification signal from the front end part of the paper sheet or the detected analog output of an A/D converter 21 and feeds it back to the A/D converter 21 to specify a reference value. This specified reference value is used to detect the digital output signal, which is A/D-converted by the A/D converter 21, as a detection pattern. Further, the detection pattern is normalized and compared with standard detection patterns by paper sheets which are stored in a memory 23 to discriminate the kind of the conveyed paper sheets, and the discriminated result is outputted.
