摘要:
An alkaline storage battery includes a positive electrode active material containing nickel hydroxide as a main component. A part of the surface of the nickel hydroxide is unevenly covered with a cobalt compound having an average oxidation number of larger than +2 and containing alkaline cations. Since only a part of the surface of the nickel hydroxide is covered with the cobalt compound, the nickel hydroxide not covered with the cobalt compound is brought into direct contact with the electrolyte, thus improving the high rate discharging characteristic. Since a part of the surface of the nickel hydroxide is covered with the high-order cobalt compound containing alkaline cations, the high-order cobalt compound with high conductivity produces a highly conductive network within the positive electrode so that the rate of using the active material is improved. In this configuration, the alkaline storage battery with high capacity and excellent high rate discharging characteristic can be provided by using a nickel hydroxide active material which permits nickel hydroxide to be brought into direct contact with an electrolyte regardless with high order cobalt oxide on the surface of nickel hydroxide.

摘要:
A biological information processing apparatus includes: a light source 11 that irradiates light 12 to a light irradiation region 13A on a test object 13; an acoustic wave detector 17 that detects an acoustic wave 16 generated by a light absorber 15 in the test object upon its absorption of the light, and outputs a detection signal; and an electronic control system 18 having an amplifier that amplifies the detection signal outputted from the acoustic wave detector 17. The electronic control system controls a gain of the amplifier in such a manner that a gain for a detection signal of an acoustic wave generated at a first location in the test object becomes larger as compared with a gain for a detection signal of an acoustic wave generated at a second location which exists nearer to the light irradiation region than the first location does.
摘要:
A delay adjustment memory is shared by two signal processing channels, a signal in one signal processing channel having a smaller delay time of the two signal processing channels is adjusted in delay by the delay adjustment memory, and another signal in the other signal processing channel having a larger delay time is directly supplied to a subsequent calculation unit without passing through the delay adjustment memory, thereby performing the ultrasonic receiving beam forming processing.

A reference circuit is described for creating a reference signal using a twin MONOS memory cell. A first portion of the twin MONOS memory cell connects to a charged and floating bit line a current source formed in a second portion of the twin MONOS cell that discharges the charged bit line to form a reference signal for a sense amplifier. The sense amplifier compares the reference signal to a signal from a selected memory cell upon which memory operations are being performed comprising read, erase verify and program verify.

A suction inlet port (48) is formed in an inner peripheral surface on a bottom portion side of a differential housing (15), and the suction inlet port (48) is connected to a suction outlet port (42) formed in an outer peripheral surface of the differential housing (15) via a suction pipe line (43). The suction outlet port (42) is formed in a mounting seat (16) to which a lubricating pump (30) is attached. A discharge port (44) introducing lubricating oil discharged from the lubricating pump (30) is formed in an upper position of the mounting seat (16), and a discharge pipe line 45 is connected to the discharge port (44). Each of a first discharge port (46) and a second discharge port (47) is formed in an end portion of the discharge pipe line (45). The suction pipe line (43) and the discharge pipe line (45) are formed integrally with the differential housing (15) by casting or the like.
摘要:
A high capacity alkaline storage battery which exhibits a maintained dischargeability and a reduced excess negative electrode capacity by decreasing the content of γ-NiOOH left in higher order positive active material. To an aqueous solution of a mixture of nickel sulfate, zinc sulfate and cobalt sulfate was gradually added an aqueous solution of sodium hydroxide with stirring to cause the crystallization of nickel hydroxide. Nickel hydroxide thus crystallized was washed, dehydrated, and then dried. To nickel hydroxide was then added dropwise a predetermined amount of an oxidizing agent (NaClO) while being stirred in an aqueous solution of sodium hydroxide which had been kept to a predetermined temperature so that nickel hydroxide as a main component was put in higher order (e.g., average valence is raised to 2.8) Subsequently, to the material was added dropwise a predetermined amount of a reducing agent (H2O2) so that the higher order nickel hydroxide as a main component was reduced (e.g., average valence is lowered to 2.2). Nickel hydroxide was washed, dehydrated, and then dried to obtain a higher order nickel hydroxide active material (positive active material).

摘要:
There is provided a received data processing apparatus of photoacoustic tomography including a minimum constitution unit data composition unit that sequentially reads receiving digital signals from first storage units and composes minimum constitution unit data of the acoustic wave of the minimum constitution units by performing a delay-and-sum processing. A second storage unit stores the minimum constitution unit data of the entire region of the specimen, and an image construction unit constructs an image of the specimen based on the minimum constitution unit data stored in the second storage unit. A control unit sequentially stores the minimum constitution unit data calculated by the minimum constitution unit data composition unit in the second storage unit and reads the stored minimum constitution unit data of the entire region of the specimen to transmit the minimum constitution unit data to the image construction unit.
