Inventor: ITAGAKI KOJI
IPC: D21H17/37
Filed: 1986-06-30
Abstract: PURPOSE:To obtain an N-vinyl formamide copolymer which is hydrophobic and suitable as, e.g., an agglutinant, by polymerizing a mixture of N- vinylformamide with a (meth)-acrylate in the presence of a radical polymerization initiator. CONSTITUTION:N-Vinylformamide (A) is mixed with a compound (B) of formula I (wherein R1 is H or methyl, R2 is 1-4C alkyl or hydroxyethyl), e.g., methyl acrylate or 2-hydroxyethyl methacrylate, at a molar ratio of component A to component B of 20:80-95:5. This mixture is polymerized in the presence of a radical polymerization initiator (e.g., 2,2'-azobis-2-amidinopropane hydrochlo ride) to obtain an N-vinylformamide copolymer consisting of structural units of formulas II and III and having a molar ratio of units of formula II to units of formula III of 20:80-95:5.

Abstract: PURPOSE:To prevent the collision between the teeth by setting one tooth width among a pinion and a ring gear relatively larger than the other tooth groove, thus facilitating the meshing between the gears on the engine side and starter side. CONSTITUTION:In a starter for an automobile equipped with a gas turbine, a spiral-shaped projection part 14 is formed onto the output shaft 7 of an electric motor 7a, and a cylindrical body 4a is installed onto the projection part 14 by a helical spline 4c. A pinion 1 is connected integrally with the clutch inner 3 of a unidirectional clutch 15 through the unidirectional clutch 15, onto the cylindrical body 14. Further, a ring gear 9 on the engine side which has the inward tooth part (b) meshed with several teeth parts (a) on the outer periphery of the pinion 1 by the rightward projection movement of the pinion 1 is installed on the same axis line to the pinion 1. In this case, the tooth width dimension N of the teeth part (a) of the pinion 1 is set so as to be smaller by a relatively large difference than the tooth groove dimension M of the ring gear 9.

Abstract: PURPOSE:To realize the supply of electric power from a fixed side to a rotary side without contacting, by driving an active circuit with the photoelectric conversion output of a solar battery mounted on a rotary cylinder. CONSTITUTION:A prescribed number of solar batteries 9 connected in series or parallel to each other are mounted on an upper end surface of a rotary cylinder 1 in order to obtain the voltage and current capacity which are needed to drive an active circuit 11 consisting of an amplifier which processes or controls picture signals, a relay, etc. At the same time, a light source 10 is provided at a fixed part opposite to the photodetecting surface of the battery 9. Electricity is conducted to the light source 10 to irradiate the light to the battery 9. Then the battery 9 converts the optical energy into the electric energy to produce the electromotive force. This force drives the circuit 11. In such a constitution, the miniaturization and high performance are attained for a rotary magnetic head device with no generation of noises. In addition, the dew condensation due to high humidity is avoided by the heating of the cylinder 1.

Title: Idle control method for internal combustion engine
Inventor: YOSHIDA MINORU
IPC: F02D41/00
Filed: 1986-06-30
Abstract: PURPOSE:To prevent hunting phenomenon, by skipping the basic duty ratio for an idle control valve properly to a small (or large) value during proper interval in which the differentiated value of idle rotation goes to zero when the idle rotation is increasing (or decreasing). CONSTITUTION:When an idle control valve 8 is duty controlled by means of an electronic control unit 12, a basic duty ratio D0 is first calculated on the basis of an actual idle rotation at that time and a target idle rotation, then stored in an executive duty ratio D1. Then, it is decided whether the basic duty ratio D0 is skipped. If the answer is YES, the basic duty ratio is skipped properly to a small value within a proper interval in which the differentiated value of said idle rotation goes to zero when the idle rotation is increasing, while when the idle rotation is decreasing, it is skipped properly to a large value within a proper interval in which the differentiated value of said idle rotation goes to zero.

Abstract: PROBLEM TO BE SOLVED: To provide a small, structurally simple, easily handling and inexpensive detecting device suitable for a simple inspection such as the existence of an ion and ionizing radiation by constituting one electrode of a bar-shaped electrode, earthing the other electrode, and surrounding the bar-shaped electrode by a cylindrical protective cover having a space between it. SOLUTION: A sensor part 2 has an installing base part 5 having a fixing screw 4 in the bottom part, a cross-sectional circular bar-shaped electrode 6 as an anode extends forward from one end side of the installing base part 5, and a cylindrical protective cover 7 having a through hole 7a extends forward so as to surround the bar-shaped electrode 6. A space 8 is arranged between the bar-shaped electrode 6 and the protective cover 7. A power cable is connected, and when AC 100 V is imparted, DC high voltage converted by the driving circuit part is impressed on the bar-shaped electrode 6 as bias voltage. The bar-shaped electrode 6 is an anode, and since an earthed one of a peripheral conductor opposed to this wholly becomes a cathode, excellent detecting sensitivity is obtained though the sensor part 2 is small.

Filed: 1981-09-30
Abstract: PURPOSE:To speed vector operation by outputting a relational operation result as a false output if the condition part of a conditional operation instruction is false when the operation result is used as the condition part of the instruction. CONSTITUTION:A write signal WE is outputted at every time even in case of a conditional operation instruction, and AND gates G1 and G2, and an OR gate G3 are provided. Therefore, in conditional relational operation, a decoder output VCSD comes to ''1'', the gate G1 is closed, and the gate G2 selects a comparison result as it is when a mask Mi is ''1'', thereby writing it in the comparison result Ci through the gate G3. In normal relational operation which is not conditioned, the output VCSD has ''0'' and the comparison result is written in the result Ci after being passed through the gates G1 and G3 as it is. When the mask Mi is ''1'', the comparison result Ci is set to ''0''. Therefore, when the comparison result Ci is used as the condition part of another conditional operation, the need for extra processing is eliminated.

Title: Paper feed device
Inventor: NABETA MASAAKI
IPC: B65H3/12
Filed: 1985-07-16
Abstract: PURPOSE:To surely separate paper sheet which are overlappedly conveyed, by floating up the paper sheets with the use of air jetted from first air nozzle to convey the same by means of a conveyer belt, and by generating a stagnation pressure between the paper sheets with the use of jet air from second air nozzles. CONSTITUTION:A suction duct 16 is connected at its downstream side to an air box 28, and jet air from first air nozzles 29 impinges upon the upper section of the leading end of paper sheets 21 which are therefore floated up. A conveyer belt 12 having absorbing holes is positioned right above the paper sheets 21, and absorbs and conveys the topmost one of the paper sheets 21. Jet air from second air nozzles 30 converges and impinges upon an air stream deflecting plate 31 which is inclined at an angle of alpha with respect to the upper surface of the paper sheets 21, and therefore, a stagnation pressure is created between the topmost one and the next one of the paper sheets 21. This stagnation pressure cancels out any suction force due to static electricity between both paper sheets, thereby it is possible to enhance the separation between paper sheets.
