Title: Level conversion circuit
Inventor: ARIMA TAKAAKI
IPC: H04L25/49
Filed: 1990-06-14
Abstract: PURPOSE:To eliminate waveform distortion due to a low frequency cut-off characteristic by converting a data signal into a ternary level data signal at a level conversion circuit. CONSTITUTION:A middle level voltage is selected as an output voltage at no input of a data signal, a high level voltage is selected as an output voltage when a data signal is logical '1' and a low level voltage is selected as an output voltage when a data signal is logical '0'. That is, gate signals S3-S5 are formed from a data signal S1 and an enable signal S2. The gate signal S4 corresponds to the data signal S1 for non-signal period, the gate signal S3 corresponds to the data signal S1 for logical '1' periods and the gate signal S5 corresponds to the data signal S1 for logical '0' period. Thus, a middle voltage V2 is selected by the gate signal S4, a high level voltage V3 is selected by the gate signal S3 and a low level voltage V1 is selected by the gate signal S5. Thus, waveform distortion due to the low frequency cut-off characteristic is eliminated.

IPC: F02D45/00
Filed: 1983-08-26
Abstract: PURPOSE:To enhance accuracy of controlling the air-fuel ratio by use of a simple apparatus, by detecting the actual pressure in an intake pipe during rotation of a crankshaft within a prescribed range of rotation of the crankshaft, and considering the mean value as the pressure in an intake pipe used for controlling the fuel injection period in an electronic fuel injection control system. CONSTITUTION:In a system, in which a fuel injection valve 6, an idling-speed control valve 13 and an ignitor 16 are controlled by an ECU 20 according to the conditions of engine operation, a turning-angle sensor 18 producing a pulse signal which rises at a predetermined turning angle of a crankshaft before the bottom dead point of suction stroke, for instance, at about 10 deg.CA and falls at a predetermined turning angle of the crankshaft, for instance, at about 20 deg.CA is provided in a distributor 17. Further, the actual presure in an intake pipe during rotation of the crankshaft within the above range of the turning angle is detected by an intake-pressure sensor 8c, and the fuel injection period is calculated from the volumetric efficiency and the mean value of the actual pressure in an intake pipe. With such an arrangement, it is enabled to simplify the apparatus since a two-dimensional map for the actual pressure in an intake pipe is made unnecessary.

Title: Earth carrying ship
Inventor: HARAKAWA YUUICHI
IPC: B63B25/04
Filed: 1978-12-19
Abstract: PURPOSE: To make it possible to open and close doors without using a drive means by making a floating-body doors hinged to the ship's slides open and close by their own weight and the buoyancy exerted thereon.  
     CONSTITUTION: When the ship is unloaded, only the lower end of floating-body door 18 is slightly dipped into the water. Since the buoyant force exerted on floating-body door 18 is smaller than its own weight W, floating-body door 18 is closed on the ship's body by its own weight W. When the ship is loaded with earth and sand to the full, almost all of floating-body door 18 submerges in the water; hence, the buoyant force exerted on floating-body door 18 becomes larger than its own weight W. Consequently, moment of the buoyant force F.l 1 , which tends to open floating-body door 18 becomes much greater than moment of the door's weight W, and further, the moment due to the pressure of earth and sand which tends to open the door operates. Hence, when sealing device 36 is unlocked, floating-body door 18 opens instantly.

Title: Right-turn/left-turn discrimination for vehicle
Inventor: ANDO HITOSHI
IPC: G08G1/0968
Filed: 1986-07-02
Abstract: PURPOSE:To enable the discriminating of right turn and left turn of a vehicle accurately, by determining a curvature radius and the current vehicle speed when a vehicle travels curving for a specified distance. CONSTITUTION:A CPU 7 judges that a vehicle makes a curves when it curves beyond a fixed angle (e.g., 40 deg.) in traveling a fixed distance (e.g., 15m). But when the curvature radius at the curving is below a fixed value (e.g., 3.5m) as criterion of reference min. rotation radius and the vehicle speed is above a fixed value (e.g., 40[km per hour]) as criterion of max. speed, a vehicle is not judged to make a curve. Judgement on the right or left turn can be made from increase or decrease in the bearing of the vehicle. The curvature radius can be determined from the distance for which the vehicle curves and the angle (radian) between bearing lines of the vehicle at both ends of the curve. This enables accurate judgement on the right or left turn free from any error in an output data of an earth magnetism sensor 1 due to disturbance.

Title: Dish washer
Inventor: MORISHIGE MASAKATSU
IPC: A47L15/42
Filed: 1989-06-20
Abstract: PURPOSE:To prevent noise by controlling the discharge power of a pump in accordance with a degree of bumps detected by a piezoelectric element on the inner wall surface of a wash tank so as to restrain the sound of bumps of water jetted from a nozzle onto the inner wall surface of the washing tank, to a lower value. CONSTITUTION:A microcomputer 21 detects a number of pulses from a discharge power detecting circuit 25 in a predetermined time so as to detect a degree of bumps on the inner wall surface of a washing tank 2. Since the discharge power detecting circuit 25 delivers a pulse when an output voltage of a piezoelectric element is higher than a reference voltage, the larger the number of pulses in the predetermined time, the higher the degree of bumps of water jetted from a nozzle 11. The degree of bumps is determined in four stages in accordance with a number of pulses, and a microcomputer 21 set a triac energizing angle of a washing pump 12' in accordance with a detected and determined degree of bumps, that is, the larger the bumps, the smaller than the triac energizing angle is set. When the triac energizing angle is changed, the discharge capacity of the washing pump 12 varies, that is, the larger the degree of bumps, the lower the discharge capacity becomes so as to restrain the degree of bumps to a small value. However, it sometimes causes the efficiency of washing to be lowered. Accordingly, the washing time is prolonged from a regulated time T0, and the number of rinsing is increased from a regulated number No.

Title: Adjacent carrier interference preventing circuit for receiver
Inventor: YUKIYOSHI YOSHISHIRO
IPC: H04B1/16
Filed: 1989-06-20
Abstract: PURPOSE:To suppress adjacent carrier interference effectively while preventing a waveform from being rounded owing to band limitation by varying and limiting the band of one carrier signal which is transmitted to a demodulating circuit according to whether the other carrier signal is large or small. CONSTITUTION:The resonance characteristics of a trap circuit 10 which is provided in front of a band-pass filter 11 are varied with a trap control signal and the band of one carrier signal which is transmitted from the band-pass filter 11 to the demodulating circuit is varied and limited according to whether the other carrier signal is large or small. Therefore, the extracting filter characteristics of one carrier signal are narrowed down in band so that the suppression effect of the adjacent carrier interference increases as the other carrier signal increases and also widened in band so that the waveform is not rounded when the other carrier signal decreases. Consequently, while the waveform is prevented from being rounded owing to band limitation, the adjacent carrier interference is suppressed effectively.
