Title: Fuel injection control device for internal combustion engine
Inventor: KAWABATA TAKESHI
IPC: F02M69/00
Filed: 1995-03-20
Abstract: PURPOSE: To correct reduction of a fuel injection amount due to increase of pressure loss of a fuel filter at the time of open loop control. CONSTITUTION: An air-fuel ratio is feedback-controlled to substantially be a theoretical value based on an output signal of an oxygen sensor 29 provided on an exhaust system during normal driving (air-fuel ratio feedback controlling). In case that the sensed air-fuel ratio is in a lean state, correction is performed so as to increase a fuel injection amount. When it is inverted to a rich state, correction is performed so as to decrease the fuel injection amount. During this air-fuel ratio feedback control, a feedback correction rate which is influenced by pressure loss of a fuel filter 24 is learned. In high rotation and load operation state, afterward, the air-fuel feedback control is suspended and shifting to an open loop control is executed.  During the open loop control, fuel pressure reduction rate due to pressure loss of the fuel filter 24 is estimated from a learning value of the feedback correction rate, and the fuel injection amount is corrected.

Title: Semiconductor light-emitting device
Inventor: FURUYA AKIRA
IPC: H01S5/042
Filed: 1988-03-15
Abstract: PURPOSE:To reduce parasitic capacitance and leakage currents, and to enable operation at high speed by forming the shapes of mutually isolated and formed trench sections to an inverted mesa shape and shaping the bottom sections of the trenches near an active layer. CONSTITUTION:A clad layer 2, a multiple quantum well active layer 3, a clad layer 4 and a GaAs layer 5 as a contact layer are grown successively onto a substrate 1 first. A pair of inverted mesa type trench sections 18, 19 having depth reaching up to sections near the active layer from the upper section of the GaAs layer and demarcating the active layer to a striped shape are formed. One conductive type first impurity region 12 having a shape along one of the mutually isolated trench sections is shaped to the trench section. A reverse conductive type second impurity region 15 having a shape along the other of the trench sections is formed to the trench section. Accordingly, since both diffusion regions are formed along the shapes of the trench sections, a space (striped width l) between the diffusion regions is most narrowed in the vicinity of the active layer, and the space is widened in other regions, thus reducing parasitic capacitance C and leakage currents.

Title: Method for sending electronic mail and warning message, and system therefor
Inventor: HENDERSON DONNIE
IPC: G06F13/00
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To enable a sender of electronic mail to discriminate between an urgent and a nonurgent electronic mail message by providing codes which control functions of a warning message and a specific escape sequence for the sender which makes the code operate. SOLUTION: When the sender generates an electronic mail, the mail appears at in a mail spool 5 of an electronic mail server 2 first. A subject list routine 6 searches the mail spool 5 for an electronic mail message including a specific code (e.g. escape sequence in the subject line of the electronic mail message). When the electronic mail message includes the code, the subject list routine 6 reads out and copies a specific part (e.g. the subject line of the electronic mail message) in the message and saves the part in a subject data base 4. Consequently, the receiver of the electronic mail can discriminates between an urgent and a nonurgent electronic mail.

At this time, the thermal medium (fluorocarbon or the like) flowing in an evaporator 1 for the thermal medium as an ex-pipe fluid is substance having a feature of high resistance in electrical characteristic as well known in the art and thus a high voltage of 10-oddkV can be applied. Due to this fact, a mere adjustment of this high applied voltage enables a load at the evaporator 1 to be easily controlled. A sectional shape of the electrode rod 11 is made into a star shape, that is, the electrode surface is divided into some segments, a distribution of an electric field is concentrated at each of the extremity ends of the divided segments, resulting in that an electric force can be improved and then an effect of promoting boiling action can be further improved.

Title: Common bus occupation control system
Inventor: YAMAZAKI YUJI
IPC: G06F13/362
Filed: 1989-03-14
Abstract: PURPOSE:To attain the flexible common bus occupation control at a high speed by finishing the transmission of an internal permission signal when the transmission is through with a 1st occupation request signal during the detection of a 1st occupation permission signal. CONSTITUTION:When the transmission is through with a 1st internal request signal, a request signal transmission means 111 finishes the transmission of a 1st occupation request signal. Then a permission signal detection means 113 finishes the transmission of the 1st internal permission signal with the end of transmission of the occupation request signal supplied also to the means 113. A 2nd occupation request signal is transmitted when a 2nd internal request signal is sent to the means 111 while the 1st occupation permission signal is not detected. Under such conditions, the transmission of the 2nd occupation request signal is delayed by the means 111 until the detection is through with the 1st occupation permission signal while detecting the 1st occupation permission signal supplied also to the means 111. Thus the flexible common bus occupation control is attained at a high speed.
