Patent number: 6603341Abstract: A charge pump circuit receives a battery voltage of a power line, and outputs a raising voltage proportional to the battery voltage. A low voltage detecting circuit detects a low voltage state in which a detecting voltage obtained by dividing the raising voltage. Thus, it is possible to indirectly detect a low voltage state in which the battery voltage is lower than a predetermined threshold value. When the low voltage state is detected, a drive circuit turns off a MOSFET. At this time, the battery voltage is temporarily varied, but the charge pump circuit has a filter action and a delay action, whereby temporary variation does not easily appear in the raising voltage (detecting voltage), and an error in operation of the MOSFET can be prevented.Type: GrantFiled: June 21, 2001Date of Patent: August 5, 2003Assignees: Denso Corporation, Anden Co., Ltd.Inventors: Naoya Tuchiya, Takeshi Ishikawa, Fukuo Ishikawa

Publication number: 20020185752Abstract: The adhesion between a protective layer, which covers a wiring layer, and a potting material, which covers a microchip, in a hybrid IC is improved without placing an additional material between the protective layer and the potting material. The potting material is separated from other electronic devices on the hybrid IC. To improve adhesion, the surface roughness of the protective layer is increased by adding insulating particles to the protective layer, striking the surface of the protective layer with ceramic particles, or replicating a mesh pattern of a screen mask on the surface of the protective layer. To keep the potting material separated from the other electronic devices, another potting material for covering the electronic devices, which is more viscous than the potting material for covering the microchip, is potted and hardened before the potting material for covering the microchip is potted.Type: ApplicationFiled: May 15, 2002Publication date: December 12, 2002Inventors: Takeshi Ishikawa, Takashi Nagasaka

Patent number: 6447934Abstract: An organic electroluminescent panel having two luminescent layers interposed between a pair of electrode layers emits white light or colored light. One luminescent layer is composed of a hole transport host material and a first fluorescent material doped in the host material, and the other luminescent layer is composed of an electron transport host material and a second fluorescent material doped in the host material. Both luminescent layers simultaneously emit respective lights which in turn are mixed into a white light or colored light.
