Title: Production of 4-amino-2-piperazinylpyrimidine
Inventor: FUJIWARA HIROMICHI
IPC: C07D239/48
Filed: 1985-10-04
Abstract: PURPOSE:To advantageously obtain the titled compound from cytosine, by acylating cytosine, halogenating the resultant acylated cytosine, reacting the resultant novel intermediate with piperazine in which either one of NH groups may be protected and hydrolyzing the resultant novel intermediate. CONSTITUTION:Cytosine is reacted with an acylating agent to protect the amino group at the 4-position with an acyl group and the acylated cytosine is then reacted with a halogenating agent to readily afford a novel 2-halogeno-4- acylaminopyrimidine in high yield. The resultant compound is then reacted with piperazine in which either one of NH groups may be protected to readily give a novel substance expressed by formula I (R1 is H, benzyl, ethoxycarbonyl or acetyl; R2 is acyl, e.g. benzoyl or acetyl, etc.), which is then hydrolyzed to carry out deacylation under mild conditions. Thereby, the aimed compound, expressed by formula II and useful as an intermediate for pyrridopyrimidine based antimicrobial compounds can be advantageously produced from naturally occurring cytosine as a raw material.

Title: Image recording device
Inventor: DAITOU CHIAKI
IPC: B41J2/385
Filed: 1983-11-25
Abstract: PURPOSE:To arrange so that high-density recording may be made at low voltage by applying a magnetized polarity and a reversed polarity created by a magnetic toner carrier means to a recording electrode adjusted to a condition where a voltage applied to a recording electrode is off and the shift of a recording medium in a facsimile unit, etc. CONSTITUTION:If a magnetic roller 12 turns clockwise and a magnetic pole shifts off the back surface of a recording electrode 10, the suction force of a toner chain 14a by magnetic power becomes weak. At the same time, if a switch 18a is closed and a magnetic field is generated by a coil 17 so that the tip of the recording electrode 10 may be magnetized as ''S'' pole and the terminal pole as ''N'' pole, a magnetic line of force from the tip of the recording electrode 10 to a recording medium 11 decreases significantly, and shows a weakened suction force on the toner chain 14a. Under this condition, if the recording medium 11 turns counter-clockwise, the quantity of moving toner particles restrained by Coulomb's force of a negative charge is large, resulting in the formation of a toner image of high concentration. Thus it is possible to obtain a picture of high concentration at low voltage.

IPC: B31B50/86
Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To prevent air from accumulating in the header and easily collect the removed piece, by fuse-cutting a grooved first engaging part by a heated cutter in the state where the first engaging part is partly connected to the header and forming an arcuate second engaging part together with the connected part by punching by a cutter. SOLUTION: The periphery of the first engaging part 17a is fuse-cut by a heated cutter. In this time, a connection part 18 is formed by leaving a part of the cutting line and the first engaging part 17a is kept connected to the header 15. Then, the second engaging part 17b is formed by punching by a circular cutter. In this way, waste removed piece 19 produced by the punching falls in only the cutting and hence the piece can be easily collected. Since the second engaging part 17b is not welded, the packaging bag is not sealed in the state where air is accumulated in the header 15.

IPC: F16H3/10
Filed: 1994-09-19
Abstract: PURPOSE: To minimize the overall axial length of a power transmission by providing a common one-way drive member operable in both a forward speed ratio and a reverse speed ratio. CONSTITUTION: An input shaft 22 drives a gear 24, which in turn drives a gear 34. A final forward drive gear 42 is driven by the gear 34 via a one-way device 36 and a friction clutch 40 to establish a low forward speed ratio. The friction clutch 40 is engaged during all forward speed ratios. To establish reverse speed ratios, only a friction clutch 64 is engaged and power from the input shaft 22 is transmitted to the one-way device 36 via the gears 24, 34. The one-way device 36 drives a countershaft 38 and gears 46, 50, which in turn drive a countershaft 52 to drive a final reverse drive gear 68 via the friction clutch 64. Therefore, the one-way device 36 is operable in both the low forward speed ratio and reverse speed ratio. Thus, the axial dimension of the transmission is kept at a minimum value.

IPC: C02F3/22
Filed: 1991-08-08
Abstract: PURPOSE:To provide an aerator capable of respectively blowing out air in the upper limit through air blowout hole parts formed in a plurality of regions different in pressure difference. CONSTITUTION:An aerator is constituted of a structure wherein pressure difference is generated in water by movement of a blade part 1 provided in a rotary shaft and air is sucked and blown out by the pressure difference through hole parts 6 formed in water. The hole parts have a structure connected from underwater to the aquatic part by air passages 5, 5' fitted to the rotary shaft. A plurality of hole parts are formed in the regions different in pressure distribution generated by the rotated blade part. The aerator has a structure wherein air is supplied in the vicinities of the hole parts of the respective distribution regions through a plurality of independent air passages. While the partition 7 of the air passages in the vicinities of the blowout hole parts is formed into a structure wherein it is partitioned and continued from underwater to the length of at least water surface in lower limit, the partition is formed longer than the rising limit by means of the relation of suction force and dead weight of liquid. The suction force acts on the air passage weaker in pressure difference and raises the water level.

Title: Pavement recovering method
Inventor: INOMATA WATARU
IPC: E01C23/00
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To achieve pavement which has high early strength and excellent durability by applying a self-curing cold asphalt mixture as a basic layer, and applying thereto a hardening resin impregnated curing cold asphalt mixture as a surface layer. SOLUTION: A self-curing cold mixture for use as a basic layer is a cold curing material which is cured by using a reaction of an added component, represented by a reaction of a metallic component such as calcium hydroxide with an organic component such as unsaturated fatty acid. This self-curing cold mixture is applied as the basic layer, and an immediate curing and highly durable cold mixture is provided on the basic layer as a surface layer to be combined with the basic layer. The surface layer is formed of a hardening resin impregnated curing cold asphalt mixture. Thus, a problem of curing failure of the cold mixture of the basic layer due to impregnation of the hardening resin of the surface layer can be solved. Further, the strength which is almost equivalent to that of pavement obtained by impregnating the entire layer with the hardening resin can be realized.  Therefore, the durability of cold recovered pavement is ensured, and the used amount of an expensive resin can be reduced, resulting in reduction of recovering construction costs.
