Title: Screen printer
Inventor: SUZUKI KAZUHIRO
IPC: B41F33/14
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To alter printing conditions automatically without waiting dry-up of ink by altering next printing conditions automatically based on the measurement data of a noncontact sensor for measuring the thickness of an undried ink on a matter to be printed. SOLUTION: A noncontact film thickness sensor 20 measures the thickness of an undried ink on a printing matter P being set on a print table 5 from one direction. A control circuit makes a decision whether the thickness of ink measured by the film thickness sensor 20 is equal to a correct value. When it is equal to a correct value, printing operation is continued according to similar procedure without altering the initially set printing conditions. When it is not equal to the correct value, a drive signal is delivered from the control circuit to a printing film thickness altering means 33 based on the difference between a measured thickness and a correct value and the printing conditions are altered automatically with no time loss.

IPC: B01D53/04
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To reduce the use amt. of an adsorbent at a time of adsorptive separation using a PSA method while obtaining high recovering efficiency even by a small-scale apparatus. SOLUTION: Component gas is adsorbed and separated from mixed gas raised in pressure by a gas compressor 1. Adsorbents 16, 17, 18 are housed in two main adsorbing tanks A3, a main adsorbing tank A3 and a sub-adsorbing tank 5 in parts. When the adsorptive separation of the gas is performed using the main adsorbing tanks A3 and the sub-adsorbing tank 5, the desorption of the gas and regeneration are performed with respect to the adsorbent 17 adsorbing the gas up to a saturation point in the main adsorbing tank B4.  The sub-adsorbing tank 5 is used in common to two main adsorbing tanks A3 and the main adsorbing tank B4 and, since the whole amt. of the gas can be recovered in the sub-adsorbing tank 5 at a time of pressure equalizing operation, the recovering amt. of the gas can be increased to a large extent as compared with a conventional method and a product gas recovering ratio can be enhanced. Since the sub-adsorbing tank 5 is also held to a collected gas atmosphere, the product gas can be held to stable high quality.

Title: Environment tester
Inventor: OKADA MASAAKI
IPC: G01N17/00
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To accurately measure the humidity in a storehouse by providing a shielding plate between an air blower and a wet-bulb sensor and eliminating the wind from the air blower from directly blowing on a part of a water absorbing body which does not cover the wet-bulb sensor. SOLUTION: A dry-bulb sensor 8 detects the temperature in a storehouse, a wet-bulb sensor 9 is covered with a water absorbing body 10 whose bottom part is immersed in water in a wick pan 11, the evaporation temperature of the water is detected, and the humidity of the storehouse is measured by the difference between temperatures detected by the sensor 8 and the sensor 9. A shielding plate 14 allows wind to blow on a part 10a of the water absorbing body 10 covering the sensor 9 but does not allow it to blow on a part 10b without covering the sensor 9 so that the evaporation amount from the 10a part is unchanged.  The temperature detection part of the sensor 9 is not affected by the evaporation flow from 10b generated by evaporating water from this part 10b so that the evaporation temperature of the water is more accurately detected by the sensor 9 and the humidity in the storehouse can be accurately measured.

Title: Stratified method of textile takeup product
Inventor: YAKUSHIJI SATOSHI
IPC: B65H67/06
Filed: 1983-01-31
Abstract: PURPOSE:To improve the productivity of labor as well as to aim at keeping off any trouble due to the missclassification of substandard yarn, by installing an entry device for a product notation in conformity with each takeup motion. CONSTITUTION:When the amount of filament yarn winding onto a bobbin 10 reaches the specified one, a turret 8 automatically rotates, while an empty bobbin 10' at the opposite side makes contact with a friction roller 7 whereby yarn changing takes place and then filament yarn Y is taken up to the empty bobbin 10'. Here, the turret 8 turns round by nearly 180 deg. and at that point that a fully winding bobbin 10 comes to a standstill, a printing device 11 goes down after its projecting toward the bobbin holder tip, and touches a part having no yarn layer at the end part of the fully winding bobbin 10, pressing this part, whereby the printing device 11 is set in motion, printing the specified notation on the bobbin end part surface. In this connection, it will do that at a point when the empty bobbin 10' is installed in a bobbin holder 9', the notation may be printed on the end part of the bobbin 10. Since a preset product notation can be automatically printed like this, trouble for spindle stratifying becomes useless and a spindle classification printing miss is eliminated.

On the other hand, at off-time of the ignition switch 60, an opening part of the one canister passage 14A is closed by the closing valve 20. When a level of fuel in the fuel tank 10 reaches a fixed position, the fuel is allowed to flow in a supply oil port side through a breather passage 14, and oil supply is stopped by detecting the fuel by a supply oil gun.

Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To stably supply a part including a curved concave high in accuracy without being affected by the material quality of a work and the like. SOLUTION: A disc shaped grinding wheel 14 which is disposed in such a way as to be directed to the direction parallel with the rotational direction D of a work 24 at a contact point with the work 24 while being located at a position off-set from the rotation center C of the work 24, is rotated.
