Title: Feeding tool in aquarium
Inventor: OGAWA SOUICHI
IPC: A01K61/02
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To provide a feeding tool capable of easily giving a feed to all fishes in an aquarium by floating a feed container on water in the aquarium, wherein the feed container is hung and supported on a decorative supporter loaded on the lid of the aquarium through a hanging line. SOLUTION: A feed container F hung and supported on a fishing rod 6 through a hanging line 7 is floated on water in an aquarium T. The fishing rod 6 is held with a decorative support S comprising a character doll and loaded on the glass lid L of the aquarium T. Therein, the top of a linear hanger 5 is allowed to approximately coincide with a virtual perpendicular line L-L passing through the gravity center G of the feed container F, and the feed container main body 1 is thereby stably held in an approximately horizontal state with the hanging line 7. A feed-receiving portion 2 capable of being filled with a flaky or granular feed f is disposed in the feed container main body 1 floated on the water in the aquarium T to form the feeding tool in the aquarium T.

Title: Rolling bearing
Inventor: HATTORI TOMOYA
IPC: F16C19/20
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To improve a rolling characteristic by stabilizing rolling action of a rolling element, in a rolling bearing having a separator. SOLUTION: On the condition that a separator 5 be formed in a shape incapable of rolling, when the separator 5 is moved in a peripheral direction according to rolling action of a rolling unit 3, while the separator 5 is guided by both shoulder parts of an outer ring 2 and stepped parts 4b, 4b of annular plates 4, 4 so as to be slid in a peripheral direction. In this way, even when the rolling element 3, at its rolling time, abuts against the separator 5, by making it difficult to act as a brake element, rolling action of the rolling element 3 is prevented from being impeded. Furthermore, by preventing the separator 5 from being easily displaced in an axial direction and diametric direction with an attitude stabilized, peripheral directional movement thereof is smoothed.

Title: Image forming device
Inventor: MAKINO MASAMI
IPC: G03G21/10
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To maintain image quality in an initial condition over a long period and to reduce running costs by discharging development impurities which increase with the increment of the frequency of use. SOLUTION: A given bias voltages are applied to a developing roller 20 and a transfer unit 34 by a high voltage power sources 32 and 36, respectively. Potential and polarity control is exerted to the high voltage power sources 32 and 36 by a controller 16. When a refresh process is specified, a second developing bias voltage having a small absolute value is applied to the developing roller 20. As a result, toner electrified to an opposite polarity and sticking to the surface of the developing roller 20 is attracted to a photoreceptor 12. Further, a transfer bias voltage having the same polarity as that of the developing bias voltage is applied to the transfer unit 34. Thus, the toner electrified mainly to the opposite polarity, as impurity, is transferred to a transfer material 40 and discharged soon.

Title: Differential amplifier for semiconductor integrated circuit
Inventor: SATO HIDEAKI
IPC: H03F3/45
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To make an output bias voltage stable. SOLUTION: Load resistors 5, 6 have the same resistance, the resistance of resistors 11, 12 used to output a mean voltage Vom (in this embodiment, Vom =Vout1=Vout2) of output bias voltages Vout1, Vout2 of output terminals out1, out2 to a detection terminal dtc is sufficiently larger than that of the load resistors and is equal to each other. A voltage comparator 8 is an operational amplifier, a designed output bias voltage VrQ is given to its inverting input terminal (-). In the case of Vom >VrQ, an output voltage of the voltage comparator 8 rises to raise a gate voltage of a current source FET 3, resulting that an operating current Is of the current source FET 3 is increased, the bias current flowing to the load resistors is increased, the Vom is decreased and controlled to be the same as the voltage VrQ.  Furthermore, in the case of Vom <VrQ, since the output voltage of the voltage comparator 8 is decreased to decrease the Is, the bias current flowing to the load resistors is decreased and the Vom is controlled to be the same as the voltage VrQ.

Abstract: PURPOSE: To easily form an insulating film on the surface of an electromagnetic steel sheet within a short period, by applying a powdery resin onto the surface of the steel sheet during the production of the electromagnetic steel sheet in an ultrarapid cooling method.  
     CONSTITUTION: A steel melt as a material for an electromagnetic steel sheet is dropped from a crucible 1 through a nozzle 2 onto a roll 3 rotating at a high speed and cooled super-rapidly, to continuously produce an electromagnetic steel sheet 5. The electromagnetic steel sheet 5 is passed through a space between temperature- control rolls 4a, 4b, so as to maintain the temperature of the steel sheet 5 at a level higher by about 10°C than the melting point of an insulating film-forming powdery resin 7 to be applied. Thereafter, the thermosetting or thermoplastic resin powder 7 injected from an electrostatic flow-dip device 6 located below the steel sheet 5 is sprayed onto the steel sheet 5 during its running toward a guide foll 9. The powder 7 is charged with high voltage electricity by an anode 6a to which a voltage of 40'60kV is charged from a high voltage power source 8. The steel sheet 5 is kept at an earth potential by the temperature-control roll 4a, so that the powder 7 closely adherse onto the steel sheet 5 and melted. Consequently, the insulating film  layer can be formed within a short period.
