Title: Method for controlling sea water desalting process of multistage flush type
Inventor: HARASHINA HEIHACHI
IPC: B01D3/06
Filed: 1989-08-30
Abstract: PURPOSE:To maintain a specified water making rate by detecting the temp. of sea water and controlling the circulation rate of brine and the outlet temp. of a brine heater according to the detected temp. CONSTITUTION:The detected value of a sea water temp. detector 33 is inputted to a setter 37. The setter 37 determines the circulation rate of the brine and the outlet temp. of the brine according to the detected temp. and outputs the indicated values thereof to a flow meter 32 and a brine temp. detector 34, respectively. The flow meter 32 controls the opening degree of a flow rate control valve 31 so as to attain the circulation rate of the brine instructed from the setter 37 and the detector 34 controls a control valve 36 so as to attain the instructed brine temp. The temp. of the brine flowing in a condenser 8 of a heat recovering section 3 falls to increase the volume of the condensate upon dropping of the sea water temp. The stable automatic operation is executed in this way while the specified water making rate is maintained.

Inventor: KARASAWA MITSUNORI
IPC: B41J29/10
Filed: 1990-08-22
Abstract: PURPOSE:To reduce the noise in printing without controlling a motor of a rotary driving mechanism by a method wherein the rotary driving mechanism is so constructed that displacement speed of a hammer decreases as it approaches a printing position even while rotary materials or the like such as a cam and a link are being rotated at a specific speed. CONSTITUTION:A boss 26 protruded from a side surface of a hammer 10 is always brought into contact with a peripheral fringe of a cam 28 by energizing force of a torsion spring 32, and the hammer 10 is made to move between a stand-by position and a printing position only by rotation of the cam 28. Further, in the case where the hammer 10 exists at the printing position, the hammer varies a magnitude of force pushing a type 16 according to a size of a character to be printed to keep printing density constant. Since for a shape of the outer peripheral fringe of the cam 28 a minimum diameter part is formed clockwise between point B and point D and a maximum diameter part is formed at a point C. Since a radius of curvature of a curve is so formed to increase as point C is approached between the point B and the point C, displacement speed of the hammer 10 decreases as the printing position is approached.

IPC: C30B29/40
Filed: 1993-09-07
Abstract: PURPOSE:To enable a polycrystal to grow making a solid obtained from a melt serve as a seed. CONSTITUTION:A part of GaAs melt 9 is made to flow into a melt pool 10 and solidified. A GaAs solid 11 is used in place of a conventional seed crystal, and a heating oven 7 is so changed in temperature gradient as to move a solid- liquid interface from a growth starting end where the melt pool 10 is located towards the other end. Therefore, the GaAs solid 11 grows after the shape of the melt pool 10, so that an operation such as seed processing or the like can be dispensed with. The GaAs solid 11 also serves to function as both a growth nucleus and a temperature monitor, so that polycrystal used for compound semiconductor material can be manufactured high in reproducibility.

Filed: 1990-08-27
Abstract: PURPOSE:To enhance data processing efficiency to a large extent by mounting a DMA receiving means directly writing the printing data of receiving data using a DMA control part when a data kind judging means judges that printing data is contained in the received data. CONSTITUTION:When receiving data is inputted from an external control part through an interface control circuit 13, the control code contained in the head part of the receiving data for instance is read by a CPU 2 and, on the basis of this control code, it is judged whether or not printing data is contained in the receiving data. When no printing data is contained, since the receiving data is composed only of the control code, usual data receiving processing is carried out by the CPU 2 and, when the printing data is contained, a DMA control part 19 is started and the printing data inputted to the interface control circuit 13 is directly written in a memory part 17. That is, since the greater part of the received data are estimated to be printing data, said printing data can be directly written in the memory part 17 without interposing the processing due to the CPU 2.

Filed: 1995-08-09
Abstract: PROBLEM TO BE SOLVED: To make improvement in startability by installing an exhaust valve to exhaust compression pressure in a cylinder in an engine, in this modeling glow engine or a type of a hot-bulb engine using such fuel as making methyl alcohol a main ingredient. SOLUTION: When operations are started, first of all, an exhaust valve open signal is outputted to an exhaust valve 20 from a controller 50 and thereby this exhaust valve 20 is opened, while a current-off signal is outputted to a glow plug 2. Next, the drive of a starter motor 40 is started, but at this time, since the exhaust valve 20 is already opened, compression pressure in a cylinder is released, thereby making the motor rotatable with very little torque. In succession, fuel is directly sprayed to the inside of an inlet port 17 from a fuel injection system 30, and an air-fuel ratio of a mixture fed into the cylinder is calculated. In case where this air-fuel ratio is so judged to be optimum, a current-on signal is outputted to the glow plug 2 and simultaneously an exhaust valve close-signal is outputted to the exhaust valve 20, starting an engine.

Filed: 1988-09-06
Abstract: PURPOSE:To increase effective DC magnetic flux for a magnetic gap by forming the outer circumference part of a bottom plate i.e., the constituting component of a magnetic circuit into a tapered shape, and making the lower surface outer circumferential diameter of the outer circumference part smaller than the upper surface outer circumferential diameter. CONSTITUTION:The outer circumference part of the bottom plate 1 is formed into the tapered shape, and it is constituted so that the lower surface outer circumferential diameter of a second magnet 4 side of this outer circumference part is made smaller than the upper surface outer circumferential diameter of a first magnet 2 side. In the magnetic circuit by this constitution, the DC magnetic flux is formed at the magnetic gap 6 by the magnet 2 and besides, by aiding the magnet 2 by the magnet 4. In this magnetic circuit, since the outer circumference part of the plate 1 is formed into the tapered shape, the magnetic reluctance of the DC magnetic flux of the loop ineffective for the gap 6 (the DC magnetic flux of the loop to circulate through the magnet 2, the plate 2, a shield cover 5, the top plate 3) is made larger so as to make the magnetic flux difficult to flow. The DC magnetic flux effective for the gap 6 is increased by using this magnetic flux decrease, and high magnetic flux density can be obtained at the gap 6 part.

Abstract: PURPOSE:To obtain a differential amplifier having the variable mutual conductance by applying the selective conduction control to plural transistors which are connected in parallel with each other and perform the differential amplification in order to change the resistances at the source sides of the transistors and to properly change the mutual conductance of the transistors. CONSTITUTION:The transistors TR T6, T5 and T2 and the TR T8, T7 and T4 which are connected in parallel to each other and perform the differential amplification are turned on when the TR P1 - P3 and P4 - P6 are selectively turned on.

In the differential amplification state, the resistance of the differential amplifying TRs change at the source sides in response to the number of selected amplifying TRs and are changed to the corresponding mutual conductances. Thus the mutual conductances of the differential amplifiers can be changed during their amplifying operations.
