Patent number: 5969445Abstract: A brushless motor which includes an arrangement to prevent dielectric breakdown of electronic parts mounted on a control board. The breakdown is caused by a heat sink which becomes electrostatically charged. The potential at the heat sink, which contacts switching devices (for instance, FETS) of the brushless motor, is equalized with the potential at one side of a source line for a drive circuit formed on the control board that includes the switching device. As a result, when the heat sink becomes electrostatically charged, the charge at the heat sink can be discharged to the source line, thereby eliminating the above problem.Type: GrantFiled: March 17, 1998Date of Patent: October 19, 1999Assignee: Zexel CorporationInventors: Kazuyoshi Horiuchi, Koji Ando, Shinichi Ohi, Mitsuji Sekiya, Kanta Arai

Patent number: 5954880Abstract: In a roller support device, an inner peripheral surface of a bearing box is covered with a material having a poor wettability with respect to a molten metal, such as tantalum, graphite, C/C composite, silicon carbide or the like. The molten metal does not adhere to the covered portion, or even if the molten metal adheres to and is solidified on the covered portion, the molten metal can be peeled off with a light force. Therefore, after a support roller is pulled up from the molten metal, the molten metal does not prevent a rolling bearing from shifting in the axial direction thereof so that the roller support device can prevent an excessive force from being applied to the rolling bearing when the support roller, after it is thermally expanded once, is contracted as the temperature falls.Type: GrantFiled: February 28, 1997Date of Patent: September 21, 1999Assignees: NSK Ltd., Sumitomo Metal Industries, Ltd.Inventors: Akio Aoki, Yukio Sato, Shin Niizeki, Takao Hashimoto, Katsuhiro Nojima, Toshihiro Mori, Koji Ando, Atsuhisa Yakawa

Patent number: 5927259Abstract: An ignition coil has a stress absorbing member with a coefficient of linear expansion which is smaller than a coefficient of linear expansion of a potting resin. The stress absorbing member faces along a circuit element of a mold ignition circuit and is buried in the potting resin. Thus, stress, caused by temperature change, which is applied to the circuit element of the mold ignition circuit from the potting resin can be reduced by the stress absorbing member. Therefore, peeling at a bonding portion of the circuit elements or at the crack can be prevented. Furthermore, the stress absorbing member is only facing along the circuit element mounting surface, and the mold ignition circuit is not wrapped by the stress absorbing member. Therefore, heat radiation from the mold ignition circuit is not suppressed by the stress absorbing member. The radiation performance of the ignition apparatus is thus improved, and the durability and credibility of the ignition circuit is improved.Type: GrantFiled: May 29, 1998Date of Patent: July 27, 1999Assignee: Denso CorporationInventors: Koji Ando, Noboru Nagase, Yasuo Tsuzuki

Patent number: 5740787Abstract: An igniter circuit is placed inside the sealing container of an associated ignition device to be sealed. The circuit is accommodated behind a partition wall inside the sealing container. The igniter includes a metallic circuit case, a substrate attached to the inner bottom surface of the circuit case, circuit elements attached to the substrate to form an ignition circuit and silicone gel that fills the circuit case. Using the adhesive properties of the silicone gel, a sheet-like protective member is place over the silicone gel to face the partition wall. The protective member may be made, for example, of aramid paper. The protective member is preferably adhesive to silicone gel, can contain gas (air) and is elastic. When the sealing container is filled with insulating resin, a portion of the insulating resin flows to the igniter from an opening of the partition wall. At this point, the protective member protects and separates the silicone gel from the inflowing insulating resin.Type: GrantFiled: December 24, 1996Date of Patent: April 21, 1998Assignee: Denso CorporationInventor: Koji Ando

Patent number: 4213517Abstract: An elevator control system includes a power source which supplies AC power to an induction motor for driving an elevator car through a first thyristor gate circuit. Another induction motor provided for braking the elevator car is connected to the power source through a second thyristor gate circuit.
