Title: Vaporized fuel processing device for internal combustion engine
Inventor: KONO AKIHIRO
IPC: F02D41/02
Filed: 1995-09-11
Abstract: PROBLEM TO BE SOLVED: To rationalize air-fuel ratio correction relating to a change of operating condition, by taking a change of purge gas flow amount into account, and learning purge concentration so that true concentration can be calculated. SOLUTION: In S35, a gain learning initial value INGALP is stored in all regions. In S32, whether KDUTY (duty correction coefficient) is 1.0 or not is decided, in S36, PRATE (actual purge rate) is compared with GPRATE (learning permission calculation purge rate), in S37, EVPTR (target purge rate) is compared with GEVPTR (learning permission target purge rate), and when all of conditions are satisfied, in S38, a new gain GNEW is calculated from a deviation eα (=100%-EVALPH) of an air-fuel ratio feedback correction amount α and the actual purge rate. In S39, a gain learning value is retrieved. In S40, a learning table value in a region corresponding to the latest purge gas flow amount equivalent area is updated. In S41, S42, a learning value of learning table in the other region is limited to an upper/lower value.

Filed: 1985-10-17
Abstract: PURPOSE:To prevent the omission of parentheses and to simplify the operation of a character processor by discriminating the large, medium and small parentheses with a single key and supplying successively these large, medium and small parentheses toward the inside from outside. CONSTITUTION:When a key input is given from a keyboard, a parenthesis counter KCO is discriminated.

Abstract: PROBLEM TO BE SOLVED: To provide a radio signal multiplex transmission method with an excellent efficiency use in terms of time and frequency where an incoming signal and an outgoing signal are transmitted simultaneously without setup of a new frequency band in radio communication between a radio base station and a radio terminal station and to provide its system. SOLUTION: A radio base station 1 transmits a non-spread spectrum(SS) signal 3 to radio terminal stations 2-1, 2-2. On the other hand, the radio terminal stations 2-1, 2-2 respectively transmit SS signals 4-1, 4-2 to the radio base station 1. In the case that the non-SS signal 3 and the SS signals 4-1, 4-2 are transmitted at the same time in opposite directions in the same frequency band, the signals are superimposed in a radio block 5. Since the SS signals 4-1, 4-2 are spread- spectrum-processed, interference with the non-SS signal 3 is suppressed and have immunity to the non-SS signal 3 that is made to be an interference signal for the SS signals 4-1, 4-2. Thus, the respective signals are correctly demodulated at receiver sides.

Title: Virtual screen control system in drawing handling system
Inventor: HISAGAI MASAMI
IPC: G06T17/00
Filed: 1982-12-25
Abstract: PURPOSE:To decrease the accesses to a recording medium in the synthesizing process of a drawing by supposing a doughnut physical virtual screen, converting said physical virtual screen into a logical virtual screen and having correspondence between the virtual screen and a real screen. CONSTITUTION:A physical virtual screen is changed into a doughnut form and regarded as a screen in which connections are secured between upper and lower sides as well as left and right sides respectively of the physical virtual screen. Under such conditions, the control of address is carried out. Therefore an address (x, y) is equal to an address (x+L, y+L), where the length of a side of the physical virtual screen is defined as L. Furthermore an address conversion table is used to have correspondence between a logical virtual screen and the physical virtual screen. Thus the screens are put on each other with no shift of a drawing A and just by writing a drawing B. As a result, the drawing B is decomposed into four corners of the physical virtual screen as shown by the oblique line parts and then written. Thus the accessess needed for synthesization of drawings A and B can be reduced greatly.

Title: Control method for actuator and device therefor
Inventor: YOSHIMATSU HIDEAKI
IPC: E02F9/20
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To reduce operation load by discriminating an operation pattern based on the amount of change of an operation signal and changing over an operation mode automatically responding to the discriminated operation pattern. SOLUTION: The manipulated variable of an operation lever 11 is converted into an electric signal M with a potentiometer. In an operation pattern discrimination section 14, an operation pattern is discriminated by the amount of change of the electric signal M. In an operation mode changeover section 15, the operation mode of an actuator is changed over automatically corresponding to the discriminated operation pattern as provided a plurality of preliminarily set patterns. The action directive signal of the actuator responding to this operation mode is output toward an actuator control means which controls the action of the actuator. Therefore, due to this construction which eliminates the troubles which disturb an operator who is required to change over manually operation mode according to the content of work one by one, the operator is allowed to concentrate on only the operation of the actuator, which makes it possible to reduce operation load.
