Patent number: 5436489Abstract: A field effect transistor includes a source electrode and a drain electrode disposed on a compound semiconductor substrate, a gate electrode having a T-shaped cross-section, and a gate pad having a T-shaped cross-section disposed at one side of the gate electrode, the gate electrode and the gate pad having a reinforcing thin metal film reinforcing the gate electrode on the rear surface of an overhanging portion of the head of the gate electrode and gate pad. Therefore, the head of the gate electrode is hardly ever separated from the leg of the gate electrode and a highly reliable T-shaped gate electrode is obtained. The gate electrode leg is produced using a thin film to which a pattern of the gate electrode is transcribed as a mask, thereby reducing the length of the head of the gate electrode. Accordingly, a T-shaped gate electrode is located in a deeper gate recess than ever without causing deterioration in the repeatability of its production.Type: GrantFiled: March 17, 1994Date of Patent: July 25, 1995Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Isao Murase

Patent number: 5193062Abstract: In an automatic test vehicle driving system on a chassis dynamometer, a table between accelerator actuator stroke and engine output torque and a table between engine friction loss power and engine speed are formed and stored by teaching operation before vehicle travel test. During travel test, command accelerator actuator strokes are determined with reference to the formed stroke-torque table when the test vehicle is accelerated or kept at a constant speed to reduce setting time for each test vehicle. Further, it is determined whether vehicle speed can be decelerated by only engine brake or by depression of brake pedal with reference to the formed friction loss power-engine speed table to prevent unnecessary braking operation. Since engine output torque can be determined in open-loop control, complicated control gain adjustment setting work can be eliminated.Type: GrantFiled: January 29, 1991Date of Patent: March 9, 1993Assignee: Nissan Motor Co., Ltd.Inventors: Isao Murase, Akira Shimozono

Patent number: 5034112Abstract: For use on automobiles, the invention provides a compact device for measuring the concentration of a nitrogen oxide in a combustion gas such as an exhaust gas of an internal combustion gas. The device has an ion pumping cell using an oxygen ion conductive solid electrolyte to adjust the partial pressure of oxygen in a gas diffusion chamber and a sensor such as an oxygen concentration cell using a solid electrolyte to detect the partial pressure of oxygen in the chamber. The pumping cell or the concentration cell is provided with a catalyst which decomposes the nitrogen oxide in the diffusion chamber only when the partial pressure of coexisting oxygen is sufficiently low.Type: GrantFiled: May 16, 1989Date of Patent: July 23, 1991Assignee: Nissan Motor Company, Ltd.Inventors: Isao Murase, Akinobu Moriyama, Takao Ito, Akira Shimozono
