Title: Acrylic emulsion composition for bonding woody material
Inventor: SHINODA KAZUYA
IPC: C09J133/02
Filed: 1994-04-15
Abstract: PURPOSE:To obtain a composition extremely useful as an adhesive for a woody substrate, especially the adhesive for veneer fancy plywood due to its excellence in resistances to warm water and boiling, etc., and further in working environment, etc., without using an amino-based condensation resin in combination therewith as opposed to a conventional adhesive. CONSTITUTION:This acrylic emulsion composition for bonding a woody material is obtained by blending an aqueous solution of ammonium zinc carbonate with an acrylic emulsion comprising a two-layer structure which is a copolymer of an aromatic vinylic monomer, an unsaturated carboxylic acid ester monomer, an acrylic monomer having amide group and an acrylic monomer having carboxyl group (a monocarboxylic acid) having -10 to +90 deg.C) Tg in a core layer and a copolymer of the aromatic vinylic monomer, the unsaturated carboxylic acid ester monomer and an acrylic monomer having the carboxyl group (a dicarboxylic acid) and having -50 to +20 deg.C Tg in a shell layer.

Title: Image forming device
Inventor: SUZUKI YASUYUKI
IPC: G03G15/09
Filed: 1988-03-30
Abstract: PURPOSE:To eliminate possibility that developer drops at the time of removing jammed paper and to prevent the stain in a machine and the stain of an image by delivering the part of a developer carrier where the developer is not carried to an exposure part at the time of opening an upper unit. CONSTITUTION:At the time of opening the upper unit 2, the opened state thereof is detected by a sensor 15. If a developer drawing member 22 is rotated till then, the rotation of the member 22 is stopped with the detection signal of the sensor 15. On the contrary, a developing sleeve 18 starts to rotate with the above-mentioned detection signal. By stopping the rotation of the developer drawing member 22, the developer is not supplied to the developing sleeve 18. And also the developer on the developing sleeve sequentially drops downward with the rotation of said sleeve 18 and it is collected in a developing tank 19. Thus, an area where the developer does not exist can be made to emerge in the exposure part 31 of the developing sleeve 18. Thus, the possibility that the developer drops at the time of removing the jammed paper, etc., can be eliminated.

Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To enable imparting a discharge lamp installation detecting function easily and at low cost to a discharge lamp lighting device in which a common terminal for a plurality of discharge lamps is connected in parallel with an inverter. SOLUTION: This lighting device is designed so that two discharge lamp detecting circuits 12a, 12b are connected in parallel with the electrode side of one of discharge lamps 4a, 4b and, if detecting that one or both of the discharge lamps are not installed, operate a control circuit 3 to reduce the power of high-frequency voltage output from transistors Tr1, Tr2. Therefore, the discharge lamp detecting circuits 12a, 12b can be installed easily without altering the connecting wires of the discharge lamps 4a, 4b. By simply replacing an inverter of the old type with the new type equipped with the discharge lamp detecting circuits 12a, 12b, the specification of the discharge lamp lighting device in which the discharge lamps 4a, 4b are connected in parallel with the inverter can easily be changed at low cost into that which can detect whether or not the discharge lamps are installed.

Title: Dc motor controlling device, its controlling method and printer
Inventor: IWAMURA KATSUTOSHI
IPC: H02P7/06
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To improve the resolving-power of an integral action without increasing the number of bits of D/A conversion in the digital control of a DC motor. SOLUTION: Control deviation ϕi is integrated and outputted as an integral action constituent OUT2 after removing the least-significant bit of the values stored in a memory 28. The same effect with that of virtually halving the gain of a control action constituent OUT2 can be achieved without enlarging the bit width of a D/A converting function, thereby making possible speedy and highly stable control at low cost by using a DC motor. Suitable to improve printing speed and quality in the printing head and the likes of a compact printer, this control makes it possible to provide a compact, high-quality printer.

Filed: 1986-04-03
Abstract: PURPOSE:To dissolve the partial abrasion of a grindstone by shifting the chamfering tool of the flexible grindstone formed into a conical shape at the same angle as the conical shape, processing the mouth section of a work hole, then shifting it along the circumference to chamfer into a curved surface shape. CONSTITUTION:The tip of a chamfering tool 2 is formed into a conical shape 2b by a flexible grindstone 2a such as a rubber grindstone. The diameter of the grindstone 2a is set smaller than that of a work hole 1a, and when the chamfering tool 2 is shifted at the same angle as the conical shape 2b, it is pressed to the mouth section 1b of the work hole 1a from the top section 2c to the end section 2d. This processing action is shifted along the circumference, and the mouth chamfered section of the work hole 1a is processed into a curved surface shape. Thereby, the tip conical shape 2b is uniformly abraded and the conical shape is invariably formed. Accordingly, the partial abrasion of the grindstone can be dissolved, the replacement life is extended, and safe processing can be performed.

Abstract: PURPOSE:To reduce the floating capacity of a floating diffusion amplifier type charge detector, and to improve sensibility by narrowing the width of a first conductivity type impurity region in a floating diffusion region up to the same extent as the width of a contact hole and forming a high-concentration impurity region under the contact hole. CONSTITUTION:In a charge detector 30, an N-type impurity region 31 continuing to a buried channel 12 is shaped, and the width R of the buried channel 12 is made the same as or smaller than that H of a contact hole 23. A high- concentration impurity region 32 is formed through the ion implantation of an N-type impurity (arsenic As<+75> or phosphorus P<+31>) from the contact hole 23. Accordingly, the width W of the impurity region 31 and the high- concentration impurity region 32 is reduced up to the same extent as the width H of the contact hole 23, thus lowering the capacity of a floating diffusion region composed with the high-concentration impurity region 32, then improving the sensibility of detection.
