Title: Controller for internal combustion engine
Inventor: MIZUTANI KOICHI
IPC: F02M25/08
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To detect the concentration of fuel vapor adsorbed into a canister during or before purge control so as to stably control an air-fuel ratio immediately after the beginning of the purge control. SOLUTION: Fuel reserved inside a fuel tank 1 is discharged by a pump 4 to be forcedly fed to an injector 7, which injects the fuel to supply it to an engine 8. When the fuel is purged to the engine 8 from a canister 14 via a pulse control valve 22, an electronic control unit(ECU) 41 calculates the purge concentration of fuel vapor to be purged based on a difference between an intake pressure during purging detected by an intake pressure sensor 32 and an intake pressure in an operating state during non-purging which becomes the same as an operating state during the purging. The ECU 41 adjusts a quantity of the fuel to be supplied from the injector 7 based on the calculated purge concentration and the engine operating state, so as to control an air-fuel ratio.

Abstract: PURPOSE:To improve the reproducing picture quality at the normal reproducing mode and to reduce wear of a recording medium and scanning stylus at the special reproducing mode by making the adjusting operation by an adjusting mechanism ineffective substantially when a video reproducing device is set to the special reproducing mode. CONSTITUTION:When a reproducing signal of a prescribed level is given to an input terminal 9, the 3rd transistor (TR) Q3 is turned off, only a resistor R3 is provided to the emitter of the 4th TRQ4, the amount of negative feedback is increased, a current flowing to a coil L2 is decreased and the standard stylus pressure being smaller in comparison with that at no signal input is provided. When the video reproducing device is set to the normal reproducing mode by a mode command means 1, since a control signal of low level is given to an input terminal 10, the 5-th TRQ5 is turned off and the 1st TRQ1 is activated in response to the reproducing signal from the input terminal 9. When the video reproducing device is set to the special reproducing mode, a control signal of high level is given to the input terminal 10, the 5th TRQ5 is turned on, a standard current flows to the coil L2 to show the standard stylus pressure.

Title: Input switch malfunction preventing circuit
Inventor: FUKUDA SHINICHI
IPC: G06F3/02
Filed: 1979-07-13
Abstract: PURPOSE: To prevent generation of interruption dependent upon a malfunction, by writing an inputtable switch pattern into a ROM previously and by adding the gate circuit, which is controlled by this ROM, to the interruption generating circuit.  
     CONSTITUTION: The next inputtable switch pattern is written at the address designated by address inputs A 0 , A 1  and A 2  of ROM 8 so that this switch pattern may be expressed by outputs P 0 , P 1  and P 2  if this address is used as the preceding switch input pattern. Gate circuits 9...11 are controlled by the output of ROM8 to output the switch input dependent upon the normal operation. Meanwhile, gate circuits 12...14 are controlled by the output of ROM 8 to cause the switch input dependent upon a malfunction to pass through. When switch 1 is turned on due to the malfunction, the input signal passes through circuit 12 and is input to FF 16 through OR circuit 15 to display the malfunction on 17 with luminescence. As a result, generation of interruption dependent upon the malfunction can be prevented.

Abstract: PROBLEM TO BE SOLVED: To obtain a signal confirmation apparatus by which the a starting signal can be confirmed easily even inside a train by a method wherein a signal which corresponds to the starting signal is received and the display of the received signal is generated. SOLUTION: A train advances to a station A, it is stopped in the communication range of a transmitter 2, i.e., in a prescribed position immediately before a start signal 1, and an antenna receives a signal from the transmitter 2. When a receiving circuit receives the signal from the transmitter 2, a lamp L is cleared once, and it is turned on again according to the contents which are received newly. That is to say, when the receiving circuit receives a blue (G) signal, the lamp L is turned on, and a buzzer B is sounded continuously. In addition, when the receiving circuit receives a red (R) signal, the lamp L is turned on in a red color, and the buzzer B is sounded intermittently. In this manner, the train driver of the train can confirms not only the starting signal 1 but also the signal even as a display inside the train.

Title: Inter-frame prediction coding transmission system
Inventor: TANOI HISAYUKI
IPC: H04B14/06
Filed: 1988-04-14
Abstract: PURPOSE:To continue the transmission of a picture data while keeping inter- frame prediction coding and to decrease the effect of occurrence of an error automatically by selecting a prediction coefficient to be less than the unity in the detection of an error of a received picture data and transmitting the information of error detection to an opposite side. CONSTITUTION:The equipment A being the sender side sends a picture data for inter-frame coding through a transmission line E, it is received by an equipment B to apply inter-frame decoding, then a prediction coefficient used for decoding in case of detecting an error in a picture data received by the equipment B is changed from the unity to a value less than the unity. Moreover, the error detection information is sent through a transmission line C and the prediction coefficient used for coding the equipment A is changed similarly. Thus, the effect of error is gradually decreased by continuing the change of the prediction coefficient for a prescribed period and the effect of error is suppressed without reducing the transmission efficiency.

Title: Friction damper device provided with speed-up gear
Inventor: KODAMA TOSHIAKI
IPC: F16L3/202
Filed: 1982-05-31
Abstract: PURPOSE:To maintain a satisfactory damping characteristic even for low cycle vibration and as well to make a damper device compact, by increasing the rotational speed of a screw rod or a nut with the use of a speed-up mechanism including gears so that the increased rotational speed is transmitted to a flywheel. CONSTITUTION:When a slow relative displacement due to a temperature variation is occurred between a pipe line system and a structure, a main casing 1 and a sub-casing 2 in a friction damper device disposed between the pipe line system and the structure move in and out so that a screw rod 3 rotates for rotating an intertial mass member 10 through a flywheel 8 and balls 12. However, when an abrupt relative displacement due to, for example, earth quake, is occurred between the pipe line and the structure, the flywheel 8 rotates in the normal or reverse direction, but the inertial mass member 10 cannot follow the rapid rotation of the flywheel 8 so that the member 10 is pressed against an intermediate wall 1c since the balls 12 run on inclined surfaces of recesses 8a, 10a. Further, a speed-up mechanism including gears 5, 6, 9 enhances the effect of damping.
