Title: Motor seal structure
Inventor: YAMAMURA MASASHI
IPC: H02K5/10
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To seal a motor surely while suppressing increase of external dimensions by forming a loading space of a yoke, an end frame and a compositional material of seal within the range of the yoke and the end frame and then loading a sealant. SOLUTION: Under a state where a brush holder 7 is fixed to a yoke 2 by an end frame 10, an annular loading space D is defined by the side face 7b of the holder 7 and the curved surface 3b of a bent part 3. The space D is not located on the outside of the yoke 2 and the end frame 10. The space D communicates with each groove 9 made in the side face 7b of the brush holder 7 and a sufficient quantity of sealant S is loaded in a motor 1 in order to prevent intrusion of liquid, and the like. Since the sealant S flowing over the space D does not flow into the groove 9 or the gap between the end frame 10 and the yoke 2, it causes no error in the dimensions of a motor assembly 1.

Abstract: PROBLEM TO BE SOLVED: To increase the strength of an electric field to be generated in the space between a bare electrode and a grounded work and also to prevent any accident due to the contact of the bare electrode with the work from occurring by disposing an electrode insulated with an insulating material between the grounded work and the bare electrode placed in a flocking chamber of the equipment. SOLUTION: In this equipment, a pile 24 is charged at the time of passing it through a bare electrode 21 and allowed to fly by an electric field generated between the bare electrode 21 and a grounded work 22 and attracted and stuck to the surface of the grounded work 22 by electrostatic force. At this time, in order to increase the strength of the electric field in which the pile 24 flies toward the work 22 from the side of the bare electrode 21, an electrode 23 insulated with an insulating material is placed between the bare electrode 21 and the work 22. Thus, another electric field is generated between the insulated electrode 23 and the work 22 to synergetically increase the strength of the electric field between the bare electrode 21 and the work 22.  Also, any arc discharged is prevented from being generated even at the time of allowing the electrode 23 to contact with the work 22 since the electrode 23 is insulated with an insulating material.

Abstract: PROBLEM TO BE SOLVED: To provide a highly decorative effect by including a board having an image recognizable by human eyes in a laminated substrate contained in a transparent cartridge to reduce the mistaking use of an optical recording medium. SOLUTION: An image recognizable by human eyes is formed in a cover board 22 by the recessed and projected parts of a board inside an optical recording medium. That is, pit-by-pit sequential exposure is performed while rotating a glass original disk coated with photoresist by a laser beam recorder, the photoresist is developed after the exposure of almost full surface, and an image pattern having recessed and projected parts is formed. Since a light reflecting state is different between the area of repeated recessed and projected parts and the area of no such parts, the area of the repeated recessed and projected parts is seen to be different by bare eyes. For example, the expanded black part of a character M is like an image pattern 32. This image pattern 32 is a collection of pits 31, and the pits 31 are arrayed in plural columns.

Abstract: PROBLEM TO BE SOLVED: To make low power loss and noise of a switching power supply unit which is so configured as to obtain its desired secondary current and voltage, by switching a primary current of its transformer. SOLUTION: After accumulation in the inductance components of a primary winding N1 and a choke coil L2, the regenerative powers of their excitation energies when a switching element Q1 is turned on, the energies are once stored in a resonance capacitor C2 by turning off the switching transistor Q1.

IPC: H05B3/00
Filed: 1993-12-24
Abstract: PURPOSE:To prevent the generation of a defective transferred image caused by the fact that a pressure roller in press-contact with a film is thermally expanded, a feeding speed for a transfer paper is changed and tensile force is generated between a transfer part, and a fixing device, in a film fixing device. CONSTITUTION:A one-way rotary clutch 13 is interposed in the driving device of the pressure roller press-contact with a fixing film 9. In a state where the pressure roller 11 is not thermally expanded, the peripheral speed VP of a photoreceptor drum 1 press-contacting with a transfer roller 5 is equal to the peripheral speed VK of the pressure roller 11, but when it is thermally expanded, the peripheral speed VK is higher than the VP and the transfer paper P tends to generate the tensile force. However, the transfer paper P is fed by the paper ejecting roller 8 of peripheral speed VH= the VP, so that the transfer paper P rotates the pressure roller 11 to obtain the state of B from the state of A. Thus, the transfer paper P does not generate the tensile force to prevent a failure in a transfer.
