Title: Magnetic recording medium
Inventor: KAMEDA NAOMI
IPC: C09D7/12
Filed: 1983-12-01
Abstract: PURPOSE:To obtain a durable medium superior in abrasion and impact resistances by forming a magnetic layer on a base and forming on this layer a protective layer composed of a copolymer of vinyl chloride-vinyl acetate-vinyl alcohol, a polyurethane elastomer, and an isocyanate deriv. CONSTITUTION:A vinyl chloride-vinyl acete-vinyl alcohol copolymer forms a comparatively hard film. The compsn. ratio of vinyl chloride to vinyl acetate is, preferably, (97-65):(3-35), and the compsn. ratio of vinyl chloride-vinyl acetate to vinyl alcohol is, preferably, (99-90):(1-10). The polyurethane elastomer forms a comparatively soft film. As the isocyanate deriv., polyisocyanates, such as tolylenediisocyanate and tolylenetriisocyanate, are suitable. The addition of said derivs. to the mixed binders of the vinyl chloride-vinyl acetate copolymer and the polyurethane elastomer forms a cross-linking structure to contribute in enhancement of resistances to abrasion and impact.

IPC: B41F7/26
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To prevent ink from being excessively emulsified and reduce the deposit of dust or the like on a blanket by a method wherein a device for directly feeding water to the blanket installed on a blanket cylinder is arranged in an offset printing machine consisting of a plate, cylinder, the blanket cylinder and an impression cylinder. SOLUTION: To a plate cylinder 21, on which a press plate 20 is installed, an ink arrangement 23 for feeding ink and a dampening water feeding device 25 are arranged and, in addition, a blanket cylinder 29, on which a blanket 27 is installed, and, at the same time, an impression cylinder 31, which presses and pinches a printing paper 30 against the blanket cylinder 29 and between the blanket cylinder 29 and the impression cylinder 31 are arranged. Further, a spraying device 33 for feeding water to the blanket 27 is provided so as to turn the water into mist in order to blast against the blanket 27.  The mist-like water, similarly with dampening water, form a thin water film at a non-image part on the surface of the blanket 27, resulting in preventing dust, the coating agent of paper and the like from being deposited onto the blanket 27 from the printing paper 30 and improving the separability from the blanket. Furthermore, by reducing the feeding amount of the dampening water from the water feeding device 25, the excessive emulsification of ink is prevented from occurring.

Title: Elevator operation device
Inventor: SUZUKI OSAMU
IPC: B66B1/14
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To eliminate inconvenience that a car is started during discrimination, and passes the called floor by permitting the address call to the desired floor to give the time allowance in the address call registry when the car arrives at the landing floor if a specified person is discriminated by a discrimination device. SOLUTION: A card reader 4 is installed on a floor where the use with outsides is frequent, e.g. on the second floor. The card reader 4 waits for the card to be read. A user comes to a landing place on the second floor, and operates his ID card in a reader head 5, and when the card is read, its ID number is collated with the pre-registered number to determine the acceptance/ rejection. If the ID number is judged to be rejection, an NG lamp of an indication lamp 6 is lit. If it is judged to be acceptance, an OK lamp of the indication lamp 6 is lit. Then, the judged ID number judges whether or not the ID number is the number of a person who is permitted to land on the desired plural floors, e.g. the third and fourth floors. This judgment is stored in a RAM 10 to light a lamp of the third and fourth floors of a permitted floor indication lamp 7.  The user waits for an elevator car to stop on the second floor.

Title: Gas transfer line
Inventor: SHIRATO KATSUYUKI
IPC: F15D1/04
Filed: 1995-09-05
Abstract: PROBLEM TO BE SOLVED: To suppress adhesion and accumulation of off-gas powder dust on the inner surface of a gas transfer line by providing a pressure air feed system to feed pressure air, an air feed pipe connected thereto and transferring air, and a pressure air injection nozzle connected to the air feed pipe and extending through the inner side wall part of a curved part and formed along the curve direction of a curve part. SOLUTION: When gas G in a gas transfer line 10 contains powder dust and mist, a control vale 13a is opened and pressure air fed in a chamber 15a is injected in a curve part 11 at a uniform pressure through a pressure air injection nozzle 14. Injected pressure air forms an air curtain A at the periphery of an inner wall part 11a in the curve part 11 along a curve direction. Since, in the air curtain A, the velocity of flow and a flow rate of the injection nozzle are formed by a uniform pressure air, an air layer having an uniform thickness is formed.  During the passage of the gas G through the curve part 11, velocity of flow reduction phenomenon occurs in the vicinity of the inner side wall part 11a but since the gas is separated away from the inner wall part 11a by means of the air curtain A, adhesion and accumulation of powder dust on the inner surface of the inner side wall part 11a are suppressed.

Title: Farm working machine
Inventor: KIMURA HIROTO
IPC: A01C11/02
Filed: 1990-08-29
Abstract: PURPOSE:To correct the inclination of a farm working machine relative to ground caused by local irregularity to the optimum parallel posture by carrying out rolling control of the machine based on the detected value of an angle sensor in place of the output of a ground sensor when the detection signal of the angle sensor exceeds a preset level over a prescribed period. CONSTITUTION:A lift controlling means A and a rolling controlling means are stored in a controlling apparatus 10 in the form of programs. The controlling apparatus 10 is provided with a detection means C and a signal switching means D. The detection means C outputs a detection signal when the detected level by an angle sensor PM3 exceeds a preset level for a preset period and the signal switching means D switches a signal in such a manner as to actuate the rolling controlling means based on the detection value the angle sensor PM3 in place of the output of each grounding sensor 6, 6 for a prescribed period when the detection signal is transmitted from the angle sensor PM3. The rolling cylinder 9 is actuated until the detection value of the angle sensor PM3 enters in a preset range, i.e., a seedling transplantation apparatus 2 gets the optimum posture relative to mud surface. The insufficient control caused by the local irregularity can be corrected by this process to perform the optimum rolling control without fail.

Abstract: PURPOSE:To prevent salts from being adhered to the inner surface of a sheet, maintain performance and useful life of a humidifier and eliminate the need for maintenance, by providing a water-softening device on the upstream side of a water-supplying port. CONSTITUTION:A water-softening device 10 filled with an ion exchange resin is fitted with a connecting pipe 10a for connection with a city water system and a connecting pipe 10b for connection with a saline source at the time of regeneration of the ion exchange resin, and softens hard water, whereby all salts dissolved in water are turned into substances well soluble in water. The softened water is supplied to a water-supplying port 3, and is introduced into a hollow porous member 1 to humidify the air passed through a heat exchanger 6. In this case, only water vapor is discharged through minute holes formed in a sheet 2 of the porous member 1, so that the dissolved salts are precipitated in the member 1. However, since a portion of dehumidifying water is continuously discharged through a water-discharging port 4, the precipitated salts are dissolved in the water, and is discharged from the port 4 to the exterior of the dehumidifier through a polyvinyl tube 4a.
