Title: Air-fuel ratio controller for internal combustion engine
Inventor: MATSUSHITA SOICHI
IPC: F02D41/10
Filed: 1989-06-23
Abstract: PURPOSE:To stabilize the air-fuel ratio in acceleration, besides the air-fuel ratio after acceleration by renewing the initial value of the acceleration increased quantity so that the integration calculation value of the fuel consumption variation quantity becomes a prescribed value and calculating the acceleration increased quantity by damping the initial value of the acceleration increased quantity by a prescribed damping rate. CONSTITUTION:When an acceleration state judging means judges an acceleration state, a transient period generating means generates the period from the time point to the time point when the fuel consumption rate variation quantity  SFC of an internal combustion engine which is calculated by a calculating means is stabilized as a transient period CTOL. The fuel consumption rate variation quantity SFC during the transient period is integration- calculated by an integration-calculating means, and a learning means learns the acceleration increased quantity initial value GACCi so that the integration calculation value SSFC becomes a prescribed value. Then, the acceleration increased quantity calculating means calculates the acceleration increased quantity TACC by damping the initial value GACCi of the acceleration increased quantity by a prescribed damping rate Galphai, and an air-fuel ratio adjusting means is drive-controlled. Thus, also the air-fuel ratio in acceleration is stabilized, besides the air-fuel ratio after acceleration, and the deterioration of the exhaust quality can be prevented.

Title: Electronic typewriter with spelling check function
Inventor: TANAKA YASUMI
IPC: G06F17/21
Filed: 1987-06-27
Abstract: PURPOSE:To simplify an error correcting operation of a word by cancelling a carriage return processing, when a spelling error is detected by a spelling check which has been executed by a carriage return key operation. CONSTITUTION:When an operation of a space key 12 is executed after a one- word input operation, a spelling check processing to its word is executed. Also, when an operation of a carriage return key 13 is executed after a one-work input operation, unless a spelling error exists, a carriage return processing is executed. On the other hand, when a spelling error is detected, it is stored in an error detection memory, and the carriage return processing is not executed. Accordingly, a carriage 5 can be moved easily to an erroneous character position of the word concerned. Also, even if a spelling error is detected, when an operation of the carriage return key 13 again continuously, the spelling error is disregarded and the carriage return processing is executed.

Filed: 1977-12-29
Abstract: PURPOSE: To form an excellent ohmic contact without forming a (pn) junction by carrying out a heat treatment after providing an electrode window to a glass film containing impurities like PSG.  
     CONSTITUTION: On the surface of P-type layer 14 on n-type Si substrate 11, the double-layer mask of SiO 2  15 and Si 3 N 4  16 is formed selectively. Thermally-oxidized film 12' after being formed is covered with PSG 17, and electrode window 17A is made. Next, a treatment is done at approximate 1100°C to soften PSG into a smooth shape. Even if P diffuses externally, P-type layer 14 is covered with masks 15 and 16, so that since the diffusion is stopped, no (pn) junction will be formed. Next, plasma etching using CF 4  makes it possible to remove selectively film 16 because of difference in etching speed. After thin film 16 is removed by being etched, the etching of PSG 17 is slight and window 17A is not expanded. Then, an electrode is formed of Al, etc., so that the device will be completed.
