Title: Impeller structure for regenerative pump
Inventor: YANAGIHARA NOBUAKI
IPC: F04D5/00
Filed: 1985-03-13
Abstract: PURPOSE:To prevent the occurrence of a backflow zone in a pressure-up water passage, by setting height of a swirl guide wall to be lower than this height in relation to that of the tooth installed in an impeller, while forming a tip end of the swirl guide wall into a spired shape. CONSTITUTION:Height H from a start end part of a swirl guide wall 3 to a tooth top and height (h) from the swirl guide wall 3 to a swirl guide wall tip end are set to be equal or H>h. And, the tip end of the swirl guide wall is formed into a spired shape whereby it is machined so as to eliminate the end face (an annular circumferential surface). Therefore, a passage section of a swirl flow grows large and, what is more, a backflow zone can be prevented from occurring in a pressure-up water passage on an extension line of the swirl guide wall.

Title: Manufacture of alkaline storage battery
Inventor: MAEDA AKIHIRO
IPC: H01M4/52
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To heighten the coefficient of use of an active material using only a slight amount of a conductive auxiliary agent by aging nickel hydroxide at a prescribed temperature for a prescribed time before initial charging. SOLUTION: This battery comprises a cathode produced by uniting, drying and pressure molding spherical nickel hydroxide, which is mixed with a fine nickel hydroxide particles, with a metal porous supporting body, an anode, a separator, and an alkaline electrolytic solution. Before the initial charging of the battery after assembly, the battery is left still at 40-80 deg.C for 24 hours or longer, so that the fine nickel hydroxide particles are aged. The fine nickel hydroxide is converted into one having a crystal structure easy to be charged and discharged by the aging.  Consequently, electricity quantity of the fine active material particles with which spaces of active material particles and gaps between the active material and a core material are filled can be sufficiently drawn out, so that a high coefficient of use is provided by using only a slight amount of the added conductive agent (e.g. cobalt compound).

IPC: G01D5/36
Filed: 1982-03-31
Abstract: PURPOSE:To make the construction of a sensor part simple by providing a disc of which the radius changes with a rotating angle at a certain function to a revolving shaft, measuring the radius of the disc at all times with an optical fiber displacement sensor, and detecting the rotating angle indirectly by calculation. CONSTITUTION:A disc 6 of which the radius gamma changes with an angle theta at a certain function is provided to a revolving shaft which is desired to measure a rotating position. A light projecting element 2 and a photodetector 3 are provided, and an optical fiber displacement sensor 7 which detects micro displacement from the difference in the quantity of reflected light is placed in the position apart by a distance (x) from the disc 6, and the value of (x) is measured. If the distance between the center of the revolving shaft and the sensor 7 is defined as R, there is the relation r=R-x. On the other hand, there is the relation of a certain function theta=f(r) between the (r) and the theta; therefore, if the (x) is determined, the theta is determined indirectly.

Title: Reversible frequency divider
Inventor: KUROSAWA RIYOUICHI
IPC: H03K23/86
Filed: 1982-03-31
Abstract: PURPOSE:To obtain a pulse signal in response to the freqency difference easily, by inputting a positive or a negative pulse signal, frequency-dividing the frequency between the difference of pulse signal frequencies and outputting the pulse signal of the frequency-divided frequency as a frequency-dividing signal accurately. CONSTITUTION:The positive and negative pulse signals 1, 2 are respectively inputted to a reversible frequency divider 15 and also to an R-S type FF16, and which of the pulse signals is inputted is stored. The content stored in the FF16 is transferred to a D type FF18 at the leading time of the signal 1 or 2. Thus, even if the content of the FF16 is changed with a new pulse signal, the content of a signal before by one is stored in FF18. When a pulse signal 18A inpotted finally is ''1'', an NAND circuit 20 blocks a negative frequency-dividing signal 4. When the signal 2 is inputted, an output signal 18A of the FF18 goes to ''0'', and an output signal 18B of the opposite polarity goes to ''1'', to block the positive frequency-dividing signal 3 with an NAND circuit 19.

Title: Oil pressure moderating device for automatic transmission
Inventor: IWATANI YOSHIMI
IPC: F16H63/02
Filed: 1988-03-08
Abstract: PURPOSE:To prevent the increase in the speed change shock at the time of a low temperature by providing a choke type throttle valve in the oil passage for supplying oil to a pressure increasing port, and always draining the same port via an orifice type throttle valve. CONSTITUTION:The oil pressure in the port 26 being a pressure increasing port has a value that is determined by the balance of the flow passage resistance of a choke type throttle valve 33 and that of an orifice type throttle valve 36. Consequently, in the steady state of oil temperature, for example, of about 80 deg.C, the oil pressure in the port 26 is set to the value in which an appropriate torque capacity is generated in the frictional elements. On the other hand, when oil temperature is low, since the viscosity of oil increases, the flow passage resistance of the choke type throttle valve 33 increases, and the oil pressure in the port 26 becomes lower than that in the case of steady state, so that the stroke of a second spool 12 is delayed. As a result, the regulating pressure by a first spool 10 decreases, thereby the torque capacity of fric tional elements also decreases, so that such a condition as to correspond to the decrease in input torque at the time of a low temperature is caused. Thus, the increase in the speed change shock at the time of a low temperature can be prevented.
