Title: Hydraulic controller
Inventor: SATOU MASAYUKI
IPC: F15B21/14
Filed: 1980-02-15
Abstract: PURPOSE: To save the fuel comsumption of a prime mover by controlling a hydraulic pump motor for making up for mechanical loss of a prime mover or the like with a position energy or an inertia energy by means of a solenoid change-over valve for a construction machine such as hydraulic shovel.  
     CONSTITUTION: As a control lever 3 is operated from O to A to lower a boom 11, a link 56 is moved to close a switch 59. Therefore, a solenoid direction change- over valve 66 goes to an upper position where a link 57 works to move a direction change-over valve 62 to the right. Oil discharged from a hydraulic pump 61 flows to the right side of a cylinder 63 to move a rod 64 to the right thereby making a hydraulic pump motor 65 ready to work as motor. The oil from the bottom side of a boom cylinder 12 passes through the solenoid direction change-over valve 66 and a pipe-line 113 to drive the hydraulic pump motor 65. Thus, a prime mover 21 is driven. At this point, while the hydraulic pump does not work, the position energy of the boom 11 is used to make up for mechanical loss of the prime mover 21 and the hydraulic pumps 68 and 69.

Title: Multiport memory device
Inventor: ISHIBASHI KOICHIRO
IPC: G11C11/41
Filed: 1995-02-03
Abstract: PURPOSE: To obtain a multiport memory which is low-cost and whose speed is high by generating a clock whose phase is different from that of an external clock, inputting a plurality of sets of address signals to an internal memory according to a second clock signal, and outputting data for a memory cell to the outside by a first clock. CONSTITUTION: When an external clock EX.CLK is input to a PLL 21 for a multiport memory device 11, the PLL 21 generates clocks CLK2 to CLK4 whose frequency is identical to that of the EX.CKL and whose phase is different from that of a synchronized clock CLK1. Address signals of respective ports A to C are input to address buffer 12 to 14 by using the CLK1. A multiplexer 15 time-divides the address signals supplied from the buffers 12 to 14 by means of the CLK2 to the CLK4 so as to be supplied to an internal memory device 16 sequentially. Data which are read out from the device 16 are output, by a data signal distributor 17, to data output buffers 18 to 20 for respective parts by using clocks CLK5 to CLK7.

Title: Manufacture of chip inductor
Inventor: URYU HIDEKAZU
IPC: H01F41/04
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a delamination between ceramic sheets by a method wherein the ceramic sheets formed by mixing heat-treated ceramic powder with untreated ceramic powder are used for a chip inductor. SOLUTION: A manufacturing method of a chip inductor is a method, wherein ceramic sheets formed by mixing heat-treated ceramic powder, with untreated ceramic powder are used for the chip inductor. According to this manufacturing method, the particles of each ceramic powder are sintered to a certain degree and when a laminated material is pressed, the ceramic sheets shrink. As this result, when a thick internal conductor is formed between the ceramic sheets, the conductor fully bites into the ceramic sheets. Therefore, a delamination is not generated between the ceramic sheets. In addition to this, as the untreated ceramic powder is also used as the material for the ceramic sheets, the density of the sheets can be made high when the particles of each ceramic powder are sintered.

Title: Optical system with flare stopper
Inventor: SATO HARUO
IPC: G02B7/02
Filed: 1994-01-17
Abstract: PURPOSE:To obtain the optical system which has a sufficient quantity of marginal light in each focusing state and also has excellent image forming performance by varying the aperture diameter of the flare stopper at the time of focusing. CONSTITUTION:The flare stopper FS which is properly varied in aperture diameter is provided in a 1st lens group G1 as a lens group for focusing, and the aperture diameter of the flare stopper FS is varied associatively with the movement of the 1st lens group G1 in focusing operation. Consequently, an oblique light beam on a wide-angle side which has a large angle of incidence is limited by the flare stopper FS which is relatively small in aperture diameter in an infinitedistance focusing state and an unnecessary light beam which causes the generation of a lower coma, etc. is cut off so that excellent image forming performance is obtained even in the infinite-distance focusing state. When the optical system is put in focus on a short-distance object point, the aperture diameter of the flare stopper FS is increased while the 1st lens group G1 is extended to the body side along the optical axis to decrease the limitation of the quantity of the oblique light beam, thereby securing a sufficient quantity of marginal light even in a short-distance focusing state.

Abstract: PURPOSE:To recover In and Sn from an aqueous solution acidified with sulfuric acid or  an aqueous solution of hydrofluorosilicic acid containing ions of In and Sn, in high recovery, by the combination of the extraction with an organic solvent containing alkyl  phosphate with the back extraction with sulfuric acid containing free sulfuric acid at a  specific concentration. CONSTITUTION:An aqueous solution acidified with sulfuric acid or an aqueous solution  of hydrofluorosilicic acid containing indium ion and tin ion is brought into contact  with an organic solvent solution containing alkyl phosphate to extract the indium ion  and the tin ion in the organic solvent solution. The organic solvent solution containing  the extracted indium ion and tin ion is brought into contact with an aqueous solution  acidified with sulfuric acid containing 550-1,000g/1 of free sulfuric acid to convert the  tin ion to the crystal of tin sulfate. The selective removal of tin can be carried out by  the above back extraction with the aqueous solution acidified with sulfuric acid. When  the concentration of the free sulfuric acid is <550g/1, the ratio of tin removal by the  back extraction is lowered and the amount of tin remaining in the organic phase is increased. When the concentration of the free sulfuric acid exceeds 1,000g/1, the amount  of indium extracted together with tin by the back extraction becomes undesirably high.

Title: Separation preventive coupling
Inventor: KAJIWARA HIDEKI
IPC: F16L21/08
Filed: 1992-02-03
Abstract: PURPOSE:To enhance work execution as well as to secure sufficient flexibility and elasticity in a coupling by providing it with a coupling main body, a spherical outer surface, a housing, a rubber ring accepted by an acceptor, and with a separation preventive coupling. CONSTITUTION:When a pipeline is expanded, a pipe 38 inserted into the faucet 14 of a coupling main body 16, is inserted to the depth of the main body 16, and when the pipeline is contracted, the pipe 38 is drawn out of the faucet 14 in response to the quantity of contraction. When the pipe 38 is drawn out, a separation preventive ring 46 is moved in the axial direction within a ring housing section 36 as the pipe 38 is moved, and when the pipe 38 is to be drawn out beyond a point where the ring 46 abuts against the tapered surface 40 of the ring housing section 36, the separation preventive ring 46 is made small in diameter by the tapered surface 40 so as to be firmly locked on the outer circumferential surface of the pipe 38, and thereby separation is prevented. Under this condition, the outer surface of the pipe 38 is supported by two points, that is, a rubber ring 22 and the separation preventive ring 46. Bending stress applied to the pipeline, however, can be thoroughly absorbed because the coupling main body 16 and a housing 26 are connected to each other in such a way as to be freely flexible over the spherical surface of an adapter 26.
