Patent number: 6831386Abstract: A stator device which prevents the formation of varnish accumulations on jumper wires, thereby preventing jumper wire breakage due to temperature variations. A gap is created between the jumper wire and the stud located on the stator body. When varnish is applied to the stud and the jumper wires, excess varnish flows through the gap and pools underneath. Moreover, when there is a significant accumulation of varnish in the gap, the varnish will flow off from the edge of the stator body.Type: GrantFiled: July 28, 2003Date of Patent: December 14, 2004Assignee: Minebea Co., Ltd.Inventors: Taiichi Miya, Naohiko Aoyama

Patent number: 6829448Abstract: A method and apparatus for image forming includes a hybrid developing apparatus that supplies surly charged toner to a developing roll. The apparatus includes a developing roll that is electrically conductive at least on its surface. The image forming apparatus and the method have a constitution capable of applying an alternating current bias having a duty ratio in the range of 10 to 50% and a direct current bias superposed thereon. The developing roll is directly confronted with a latent image bearing body through an insulative toner thin layer at the nearest region of the developing roll and the latent image bearing body. An independent bias is applied to each of the developing roll and the magnetic roll, and the toner is refreshed by the varying duty ratio of the alternate current bias and the direct current bias after developing.Type: GrantFiled: March 25, 2003Date of Patent: December 7, 2004Assignee: Kyocera CorporationInventors: Yoshio Ozawa, Yuji Kamiyama, Shoichi Sakata, Toshinori Nishimura

Patent number: 6810091Abstract: There is disclosed a reduced-scale digital data deinterleaver of simple structure. In a preferred embodiment each word is comprised of 32 bits of data, and 32 words form a block. In each block, each word is separated into four phases cyclically. The resulting bit lines and word lines are interchanged to produce interleaved data items. One block of the interleaved data items is written into a RAM. A higher significant address of 5 bits and a lower significant address of 5 bits of the RAM are specified by the higher significant 5 bits and the lower significant 5 bits, respectively, of the output from a counter. Whenever a block of data is written to the RAM the higher significant 5 bits and the lower significant 5 bits are interchanged to produce first and second count signals. Data is read from the specified address, 1 bit at a time and data is written, 1 bit at a time, into the address just from which data was read out.Type: GrantFiled: April 21, 1999Date of Patent: October 26, 2004Assignee: Nippion Precision Circuits, Inc.Inventor: Hiroyuki Kawanishi

Patent number: 6764307Abstract: The retainer of the present invention is made of a composite material having a body made from a polymer, a layer of solid lubricant formed over the body by chemically coating the body with a porous layer of solid lubricant and impregnating the solid lubricant with another lubricant using conventional methods such as vacuum impregnation. The retainer is placed between an outer raceway and an inner raceway to form a self-lubricating bearing. The bearing made in this manner has high lubrication tolerance (i.e. it performs well in the absence of external lubrication). Because of its high lubrication tolerance, the bearing is suitable for use in various applications such as dental/medical hand pieces that are periodically sterilized and other applications which occasionally experience periods of lubrication starvation.Type: GrantFiled: March 28, 2001Date of Patent: July 20, 2004Assignee: Minebea Company, Ltd.Inventor: Alex Metrikin

Patent number: 6713699Abstract: A key switch stabilizer mechanism having a first approximately C-shaped stabilizer wire which is connected to both a key top and a base plate, and is further supported so as to be able to turn with respect to the key top; and a second stabilizer wire having a flat portion connected to the base plate, a bent portion, and another flat portion connected to the key top. Therefore, touching even very lightly any part of the key top surface, in particular the top end peripheral edge, allows a pushing pressure to be imparted to the first and second wires arrayed within the key top, by means of which a membrane push mechanism operates. When pressure on the key top is released, the first and second stabilizer wires follow the reaction force from the membrane switch push mechanism and rise, such that the membrane switch can be operated.Type: GrantFiled: March 13, 2003Date of Patent: March 30, 2004Assignee: Minebea Co., Ltd.Inventor: Masayuki Yoneyama

Patent number: 6683264Abstract: This low profile key switch structure provides a substantial reduction in the height or thickness of a key switch as compared to conventional and other low profile switches. Substantial height reduction in key switch structures allows the size and thickness of notebook-type personal computers and the like to be similarly reduced. One feature of this low profile key switch structure is that unlike in conventional key switch structures the membrane switch and frame structures do not over lap to cause unnecessary height in the structure. Another feature of this key switch structure is that the frames are formed to include the free motion range limiters. The frames are further formed so that they may be embedded in the reinforcing base plate in such a manner that allows the height of the key switch to be further reduced. This low profile key switch structure is also designed to eliminate unwanted key top movement that often occurs in conventional and other switches when the key top is depressed.Type: GrantFiled: April 4, 2003Date of Patent: January 27, 2004Assignee: Minebea Co., Ltd.Inventors: Rikuro Obara, Masamitsu Osada, Masayuki Yoneyama

Patent number: 6612762Abstract: The present invention is intended to provide an economical printer which is simple in structure and uses a common tray but is capable of adapting itself to various recording media of different shapes. Adapters in which recording media can be firmly held can be selectively mounted in the tray. An adapter 24 has an oval opening 24a in which a recording medium 30 can be placed. The contour of the adapter 24 can fit into a recessed portion 23a formed in the tray 23. The recording medium 30 is firmly held in the adapter 24. When the adapter 24 is mounted in the recessed portion 23a in the tray 23, a keyway 23b and a protrusion 24b engaging the keyway 23b prevent the adapter 24 from shifting out of position; the adapter is held in the tray 23. Prints can be made in accurate positions on the recording medium 30.Type: GrantFiled: May 30, 2000Date of Patent: September 2, 2003Assignee: Seiko Precision Inc.Inventors: Motoharu Sakurai, Satoru Tada, Naoki Tanabe, Mikio Amakasu

Patent number: 6594161Abstract: A power converter having a transformer with a primary side winding and a secondary side winding, each having a switch. When the primary master switch is switched on, the transformer charges. When it is switched off, the intrinsic capacitance of the secondary slave switch discharges generating the zero voltage switching condition for the secondary slave switch. The secondary slave switch is switched on at a time determined in accordance with the waveform generated by the transformer. When the secondary slave switch is switched on, the transformer discharges and ultimately the charge from an output capacitor flows into the transformer as a backflow which charges the transformer. The secondary slave switch is switched off at a time determined in accordance with a current flowing through said secondary switch. The intrinsic capacitance of primary master switch discharges generating the zero voltage switching condition for primary master switch which is then switched on.Type: GrantFiled: November 9, 2001Date of Patent: July 15, 2003Assignee: Minebea Co., Ltd.Inventors: Arian M.
