Title: Filter device using filtration membrane
Inventor: ISHIGAKI EIICHI
IPC: B01D63/02
Filed: 1993-10-25
Abstract: PURPOSE:To easily perform regeneration and replacement of a filter medium by a method wherein a filter room using filtration membranes is divided into small chambers so as to bear high pressure, and cylindrical filtration membranes are parallelly disposed in each of the chambers, wherein the filtration membranes are superposed on one another to form a filter device having a large filtration area and these chambers can easily be opened and closed. CONSTITUTION:Filtration plates 3 each having therein an inwardly recessed filtration room are parallelly, slidably arranged on a pair of parallel rods 2, wherein sealing surfaces are formed on the periphery of the plates 3, so that when these plates 3 are closed, the sealing surfaces are brought into close contact with each other, thereby forming a sealed filtration chamber. Further a large number of cylindrical filtration membranes are parallelly installed in the filtration chamber, while, in the plates 3, there are provided fluid passages 11 which communicate with the filtration chambers and which communicate with each other when the plates are closed, and fluid passages in communication with inner cavities of filtration membranes 10.

Title: Injection timing control device for fuel injection pump
Inventor: ENOMOTO SHIGEIKU
IPC: F16K31/06
Filed: 1995-11-08
Abstract: PURPOSE: To decrease a lift amount and increase a responsiveness to valve opening by setting a hydraulic control valve so that the diameter of a shield edge in which the conical surface of the valve needle is brought in contact with a valve seat of the hydraulic control valve is approximately equal to the diameter of the needle. CONSTITUTION: When current flows through a coil from an electronic control device, a valve needle 43 moves to a valve opening position and fuel in a timer high pressure chamber 22 flows into a timer lower pressure chamber 24, and thus a pressure in the high pressure tank 22 lowers, a timer piston 21 is moved upward in the figure by a spring 25, and an injection timing is changed in the direction of delayed angle. In this case, at the seat part of a control-valve 27, the diameter of a shield edge in which, when the valve is closed, the conical surface of a valve needle 43 is brought in contact with the conical valve seat 37 is set at the same value as that of the diameter of the valve needle 43, and thus a lift amount can be reduced. Therefore, because air gap is also reduced before the coil attracts an armature, the number of windings of the coil can be reduced.  Thus the responsiveness to valve opening of a hydraulic control valve 21 is improved.

IPC: G06F3/12
Filed: 1991-10-09
Abstract: PURPOSE:To execute a ruled line processing so as not to change a printing image by returning a ruled line enlarging direction to an enlarging direction before transformation when a ruled line enlarging direction after the transformation is different from that direction before the transformation in the case of enlarging ruled line width by executing density transformation to image data having different resolution.

The processor 3 executes the processing control of the image data and outputs the printing image to a printing mechanism part 20. A density transformation part 6 executes a density transformation processing so that the image data having the different resolution (240dpi) from the outside can be transformed into the image data having the own resolution (400dpi). The transformed image data are stored in an image memory 4. On the other hand, the line width enlarging direction after the density transformation is temporarily stored in a density transformation storage part 7, and the processor 3 instructs plotting to the printing mechanism.

Abstract: PURPOSE:To easily and accurately measure a sea level at an arbitrary location by discharging ultrasonic waves to the reflector installed in the place whose height above sea level is known, by receiving the reflection ultrasonic wave from the reflector and by calculating the time from transmission to reception. CONSTITUTION:The ultrasonic waves discharged from the transducer 4a ar ranged on a ship 1 is reflected from the reflector 5 mounted on a break water 6 and return again to the detector 4c on the ship 1, a reflection time calculating means calculating the time from transmission to reception of a ultrasonic wave. This time is input in a conversion section 7 to be displayed being converted into the distance X(between the transducer 4a and reflector 5) on a display section 3. The line segment extended in the vertical direction from the reflecting point of the reflector 5 and the horizontal line passing through the transducer 4a are made to cross to take the vertical line segment and horizontal line seg ment as Y and Z respectively. Since the velocity of ultrasonic waves is about 340m/second, X=340X(reflecting time/2), and since Z is known quantity, Y=(X<2>-Z<2>)<1/2>. The fluctuation segment of this vertical line segment Y is equal to the fluctuation segment to the reference sea level.

IPC: G06F13/28
Filed: 1996-11-01
Abstract: PROBLEM TO BE SOLVED: To avoid the deterioration of bus using efficiency even when a proper burst transferring quantity of the opposite side of DMA transfer is unknown. SOLUTION: When a transfer suspending signal is given to a DMA transferring device 1, the device 1 interrupts burst transfer.

Filed: 1988-11-17
Abstract: PURPOSE:To prevent erroneous lighting by resetting the lC counter of a sequence lighting control circuit to an initial mode when a commercial power supply is turned on at the time of power failure recovery and the like. CONSTITUTION:An off-start circuit 20 detects the time when a commercial AC power supply 1 is turned on, and outputs one shot pulse reset signal to the reset terminal R of an IC counter 14, thereby resetting the counter 14 to an initial mode. when the power supply 1 is properly turned on, the counter 14 operates independent of the circuit 20. when power failure takes place and then recovered, the NAND circuit 21 of the circuit 20 outputs a shot pulse signal, thereby resetting the counter 14. According to this construction, the output terminal P1 of the counter 14 becomes a high level immediately after the recovery of the power failure and a relay RY1, operates, thereby opening a contact S1 and turning off a fluorescent lamp 3. Consequently, erroneous lighting is always prevented.

Title: Enclosed lead storage battery
Inventor: YAMASAKA KOICHI
IPC: H01M4/56
Filed: 1986-12-08
Abstract: PURPOSE:To facilitate a temperature control in the manufacture of a positive electrode lattice by specifying the amount of tin oxide mixed with a positive electrode active material. CONSTITUTION:Tin oxide is mixed 15% or less in a weight ratio with a positive electrode active material. Therefore, when a Pb-Ca alloy is used as a positive electrode lattice, the tin oxide in this positive electrode active material exists in a film of lead sulfate generated on an interface between the positive electrode lattice and the positive electrode active material, and conductivity is provided to the film, so that passivation can be suppressed. Therefore, a three-element group alloy of Pb, Ca, and Sn need not be used as the positive electrode lattice, and so a temperature control can be facilitated in the manufacturing process of the positive electrode lattice.

Title: Voice reproducing device
Inventor: SUGIMORI MASAAKI
IPC: G11B20/02
Filed: 1993-11-22
Abstract: PURPOSE:To easily recognize a whole context at a special reproducing time. CONSTITUTION:A reproducing voice signal obtained according to the traveling speed of a tape is A/D-converted and written in a memory 22 while a memory gate pulse (GP) is generated. The gate pulse (GP) is generated when a finish address value (SA) becomes almost equal to a read-out address signal (RA) and continuously generated until the read-out address signal (RA) becomes almost equal to address information (AD). Thus, the gate pulse (GP) whose time width is longer than one circuit of the address information (AD) is formed. Therefore, the reproducing voice signal (A/D converting output) continuously written in the memory 22, that means, continuously read out from the memory 22 becomes longer than one circuit of the address of the memory 22.
