Title: Structured document converter
Inventor: TONOMURA YOSHINOBU
IPC: H04L13/00
Filed: 1986-07-31
Abstract: PURPOSE:To attain handling of a structural document data such as a mix mode including a drawing by providing an image memory expanding image information corresponding to a page. CONSTITUTION:When a data outputted from a reception buffer memory 1 is a block of a character code, it is converted into a character pattern by a character pattern conversion section 3. In case of a block of facsimile image, a decoding section 4 decodes the facsimile image data, and in case of a block of drawing command, it is converted into a drawing pattern by a drawing generating section 5. The conversion data is expanded on one face of the image memory 7 by a control section 6 according to the structure information included in the reception data. In completing the processing by one block, the data of the memory is coded by a coding section 8 from the upper end of the page as to the line whose content in the said page is confirmed and the result is outputted to a transmission buffer memory 2. The similar processing is applied also to the next processing block succeedingly.

Inventor: ITOU YUKIHIRO
IPC: G03G21/00
Filed: 1981-11-12
Abstract: PURPOSE:To catch even fine particles and increase the quantity of caught particles, by using a purifier where an internal filtering type purifying means is arranged in the preceding stage in the direction of flow-in of air and a surface filtering type purifying means is arranged in the succeeding stage. CONSTITUTION:Fine particles of a developing powder are carried to a filter 6 through an air duct by a discharge blower 7. Most of fine particles are caught on an internal filtering type filter 14 in the filter 6 by adhering. A small quantity of particles passing through the filter 14 are caught on a surface filtering type filter 15 arranged on the inside face of the filter 14. Therefore, the time required for causing clogging becomes about 6 times as long as that in case of the use of only the internal filtering filter. Thus, the running cost is reduced considerably.

IPC: C08L91/00
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To obtain a thermoplastic resin compsn. which has excellent adhesion to a substrate, adhesion to a printing ink or a coating, and secondary processability such as coating by incorporating a thermoplastic resin and a hydroxyl-contg. fatty acid or a deriv. thereof. SOLUTION: This thermoplastic resin compsn. comprises: a thermoplastic resin; and a hydroxyl-contg. fatty acid or a deriv. thereof. This resin compsn., when printed or applied to moldings having various shapes, develops high adhesion to an ink or a coating. In particular, the resin compsn., when brought into contact with water during use thereof, an org. solvent, such as an alcohol or kerosene, hardly causes a lowering in adhesion. This compsn., particularly in the case of a nonpolar polyolefin resin, has high adhesion to a substrate and excellent adhesion to an ink, a coating or the like. Further, by virtue of the adhesion, there is no need to enhance the molding temp. Therefore, it is possible to reduce the occurrence of an offensive odor and emission of smoke at the time of molding and a deterioration in heat sealing properties and mechanical strength.

Title: Film forming method
Inventor: SAKAI KUNIHIRO
IPC: B05D1/18
Filed: 1984-09-03
Abstract: PURPOSE:To improve the adhesiveness between a substrate and monomolecular film and to prevent the exfoliation of the film in a film forming method which is applicable for production of biochips by using a liquid mixture composed of water and alcohol as an aq. phase. CONSTITUTION:Water soluble alcohol such as ethyl alcohol or methyl alcohol which has the b.p. lower than the b.p. of water is used as the alcohol at 5-25wt% content by the weight of pure water. The soln. of a film constituting material dissolved in a volatile medium such as benzene or chloroform is dropped onto the liquid surface 3 of a liquid tank 1 contg. the above-mentioned liquid mixture as the aq. phase and is diffused on the surface 3. The monomolecular film is formed by facing downward the hydrophilic group and facing upward the hydrophobic group on the surface 3 when the solvent volatizes. A film forming frame 4 is thereupon moved to reduce the region of the surface 3 and to intensify the interaction among the molecules, thereby forming a two-dimensional solid film. When the substrate 5 is vertically moved in this state, the monomolecular film formed as the above-mentioned solid film is stuck and transferred onto the surface of the substrate 5.

Title: Automatic on-off and circuit selector using 'radio calling receiver'
Inventor: SUNAKAWA KUNIO
IPC: H04W92/08
Filed: 1996-06-08
Abstract: PROBLEM TO BE SOLVED: To remotely control an object by activating an operation sequence with a reception output of a radio receiver called by a radio wave. SOLUTION: A desired object is specified by calling the radio calling receiver with a usual method. The called receiver receiving a number provides an electronic output of a conventional buzzer or vibrator for a terminal A. A coil B receives the electric output at the terminal A to generate an electromagnetic force in an iron core C of an electromagnet. An iron piece E is attracted by the iron core C against a tension of a spring D with the electromagnetic force of the iron core C. A contact G is in contact with a contact F by the operation of the iron piece E to make a circuit between terminals H, I conductive. The terminals H, I close a self-hold circuit or the like such as a logic sequence circuit to start the object.  For example, when a radio calling telephone set of an automobile parking on a place under the burning sun is called by a prescribed number, the receiver starts an engine and drives a cooler.

Title: Magnetic recording medium
Inventor: WATANABE NOBORU
IPC: G11B5/716
Filed: 1985-08-20
Abstract: PURPOSE:To permit magnetic recording and reproduction over a wide frequency range at a high density by forming the 2nd magnetic layer in which magnetic particles having large coercive force are oriented in a vertical direction or non-oriented on the 1st magnetic layer in which the magnetic particles are oriented in the longitudinal direction in such a manner that said layer is thinner in thickness than the 1st magnetic layer. CONSTITUTION:The acicular magnetic particles of, for example, iron oxide having the coercive force as low as 200-300Oe are coated on a base 1 and thereafter the 1st magnetic layer 2 subjected to the intra-surface orientation is formed thereon. The planar magnetic particles of, for example, barium ferrite having about 500-1,000Oe coercive force larger than the coercive force of said magnetic layer 2 are coated thereon and thereafter the 2nd magnetic layer 3 subjected to the vertical orientation or non-orientation is formed thereon. The thickness of the magnetic layer 3 is preferably <=1mum. A long wavelength component is recorded by a longitudinal recording system to the magnetic layer 2 and therefore, the demagnetization field is small. On the other hand, the short wavelength component is recorded by a vertical recording system to the magnetic layer 3 and therefore, the demagnetization field is small. The recording and reproduction with the small demagnetization field are thus made possible from the short wavelength component to the long wavelength component.

Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of a switching regulator during light load. SOLUTION: The output voltage of a switching regulator and the output of a reference voltage circuit 10 are inputted to an error amplifier 13, which outputs a difference voltage between them. The difference voltage and the output of a reference voltage circuit 110 are inputted to a compactor 115, which discriminates whether or not, the differential voltage is higher than the reference voltage. An oscillation circuit 114 is constructed so as to change an oscillation frequency in accordance with the discriminating result. If the difference voltage is lower than the reference voltage, the oscillation frequency is lowered so as to lower a switching frequency, and efficiency during light load can be improved.
