Title: Fuel injection controller for engine
Inventor: SASAKI TAKEO
IPC: F02D41/36
Filed: 1988-08-19
Abstract: PURPOSE:To make it possible to detect a misfire inexpensively and surely by discriminating a misfire cylinder with a misfire sensor detecting deflection of an engine, and when a misfire state has continued as long as more than the specified time, stopping a fuel injection valve for the said cylinder. CONSTITUTION:A signal of a misfire sensor 5 detecting deflection of an engine 1 attached to a car body is transmitted to an electronic controller 10. Then, a signal process is carried out by a microcomputer 102 and a misfire is judged, while a phase angle between a crank angle signal 7a of a crank angle sensor 7 and a cylinder discriminating signal 7b of a crank angle sensor 7 is found, thereby discriminating a misfire cylinder. Here, when a misfire has continued in a specified cylinder as long as the specified time in succession, operating time of fuel injection valves 6a-6d for the said cylinder is set to zero, namely, their injection is stopped. With this suspension, any fuel supply to the said cylinder is cut off, and thereby unburnt gas is prevented from occurring. Therefore any damage to a catalyzer is obviable in a way of very low cost.

Title: Multidisk frictional engager with unified drum and retaining plate
Inventor: KITABAYASHI NAGAARI
IPC: F16D13/52
Filed: 1993-07-30
Abstract: PURPOSE:To aggrandize the extent of transmission capacity despite small in size by unifying a drum and a retaining plate as one body, and forming an opening part at the side of a piston of this drum. CONSTITUTION:Both inner and outer disks 32 and 33 are built in a drum 31 from the side of an opening part 39 and then a piston 36, a side plate 46 and a snap ring 40 are all built in as well. Therefore this piston 36 is formable to be larger than a circle to be made up at a top face 60 of a key 34. With this constitution, an outer diameter of the piston 36 is made larger without enlarging that of the drum 31, thereby making the pressing force of this piston 36 increasable. During torque transmission, the pressing force of the piston 36 is added to a retaining plate 37, and tangential force made by a spline 38 of the outer disk 33 and centrifugal force of the outer disk 33 both are added too. However, the retaining plate 37 and the drum 31 are unified as one body and reinforced with each other in terms of structure, so it is unnecessary to lengthen the drum 31 and to thicken this drum 31 and the retaining plate 37. Accordingly, any possible enlargement in this drum 31 is thus avoidable.

IPC: H03L3/00
Filed: 1993-07-29
Abstract: PURPOSE:To suppress the delay of an output signal at the time of its production and to suppress the generation of jitters by producing the output signal from a prescribed phase in accordance with the output of a free-running oscillator and a prescribed transition point of a control signal. CONSTITUTION:An oscillator 2 produces a sinusoidal wave signal cos (omegat+alpha) and supplies it to a phase splitter 10. The signals of the same phase undergone the division of phase are outputted to a node 11, and an orthogonal sinusoidal wave signal sin (omegat+alpha) is outputted to a node 12. The sinusoidal wave signals of the same phase supplied from the splitter 10 are inputted to a 4-phase multiplier 31 and a track holding circuit 21. The circuit 21 has the track and enable states according to the 1st and 2nd states of the control signal supplied from a control signal source 20 respectively. The output of the circuit 21 is inputted to the multiplier 31, and the multiplication output of the amplifier 31 is sent to an adder 40. The output of the splitter 10 is inputted to a track holding circuit 22 and a multiplier 32. A positive control signal and a sinusoidal wave signal are multiplied by each other by the multiplier 32 and added together by the adder 40. Then a fixed output and a sinusoidal wave signal are outputted in the 1st and 2nd states respectively.

Title: Step feed actuator device having variable stop position
Inventor: NOTOHARA YASUO
IPC: G05D3/00
Filed: 1984-10-04
Abstract: PURPOSE:To stop an actuator device at an optional position and also to attain the miniaturization and high working efficiency of said device by providing a sensor at a position opposite to a mobile part for the generation of an n-phase output. CONSTITUTION:A sensor 3A is set opposite to the mobile part 2A of an actuator and produces outputs A and B of two phases different from each other by 90 deg.. A signal processing circuit 6A produces signals (a) and (b) and their adversely converted signals (-a) and (-b) according to both outputs A and B of the sensor 3A. An electric current command circuit 5A selects just one of those signals (a), (b), (-a) and (-b) sent from the circuit 6A based on the commands thetaP and thetar given from a command production circuit 7A. Thus a current command signal iC is produced according to the signal selected by the circuit 5A. A stop position varying circuit 8A changes the bias of the signal iC and produces a correction current command signal iCO. A current control circuit 4A controls the current (i) of a fixed part 1A or the part 2A of the actuator based on the signal iCO. Thus the direction and the level of the current of the actuator are decided by the signals (a), (b), (-a) and (-b) obtained by the outputs A and B of the sensor 3A.

When the contour is similar to the inside shape of the container, the gap to the internal wall of the opening part is reducible. When the container is made of a material larger in specific gravity than the liquid, a hollow part is formed so as to make the bulk specific gravity smaller than the specific gravity of the liquid. The material of the float member 5 need to be selected so that the liquid composition is not affected.

Title: Semiconductor storage device
Inventor: MIYATAKE HIDEJI
IPC: G11C11/409
Filed: 1990-08-03
Abstract: PURPOSE:To minimize the loss of reading voltage even when an integrated degree is improved by executing the precharging operation of a reference bit line by a precharging means also at the time of memory cell connecting operation. CONSTITUTION:When storage data from a memory cell are read in a selecting bit line SBL, the electric potential of the selecting bit line SBL ascends/descends for DELTAV1 than 1/2 Vcc corresponding to the storage contents of the memory cell. On the other hand, since a reference bit line RBL in precharging, even when some electric potential change is generated by capacity coupling between the selecting bit line SBL and the reference bit line RBL to the reference bit line RBL, the electric potential is recovered quickly. Accordingly, an electric potential difference between the selecting bit line SBL and the reference bit line RBL becomes DELTAV1 substantially and reading voltage is not lost.
