IPC: G06F3/023
Filed: 1981-04-13
Abstract: PURPOSE:To realize a display of a various types of display contents by switching and with a key and facilitate the versatility of input information to a keyboard device, by displaying the information supplied based on the selection information to a display medium at a keying part. CONSTITUTION:An external controller transmits the selection information to a display control part 8 to select a character pattern to be displayed. Based on this selection information, the part 8 reads the pattern information out of a font memory 11 and stores it in a display memory 9 to display it on a liquid crystal display 6 for example via a driving circuit 10. Thus a desired character pattern is displayed at the upper surface part of a key 2. With push of this key 2, the proper key information is transmitted to the external controller. The external controller decides the keyed key input information from the proper information of the key 2 and the above-mentioned selection information.

Title: Controller for engine with supercharger
Inventor: YAMASHITA AKIBUMI
IPC: F02B39/16
Filed: 1987-03-10
Abstract: PURPOSE:To perform optimum supercharging pressure control, by connecting a first pressure lead-in passage, provided with an on-off valve leading in pressure at the down-stream of a supercharger, and a second pressure lead-in passage leading in suction pressure between the supercharger and a throttle valve both to a pressure chamber of a bypass valve. CONSTITUTION:At a supercharging area at the time of high load or the like, supercharging pressure is led into a pressure chamber 13 of the actuator 10 connected to a bypass valve 11 via a first pressure lead-in passage 15. Since pressure to be led from a second pressure lead-in passage 16 is almost equal to atmospheric pressure, if an on-off valve 18 is opened, pressure acting on this actuator 10 comes to such a form that it leaks. Pressure at the pressure chamber 13 of the actuator 10 is controlled whereby the supercharging pressure is controlled. At a nonsupercharging area at the time of idling or the like, the on-off valve 18 is fully opened, and since negative pressure is led into the pressure chamber 13 of the actuator 10, the bypass valve 11 is opened, thus suction air flows bypassing the supercharger 4.
