An electrophotographic toner is formed as a blend of toner particles and external additives. The external additives include (1) first inorganic fine particles having an average primary particle size of 80-800 nm of oxide of a metal selected from the group consisting of titanium, aluminum, zinc and zirconium, (2) second inorganic fine particles other than silica having an average primary particle size of below 80 nm and (3) silica fine particles having an average primary particle size of below 30 nm. As a result, the toner can be made free from difficulties, such as melt-sticking onto an image-bearing member in a low humidity environment, roughening of halftone images in a low humidity environment, toner blot-down after storage at high temperatures or in continuous image formation on a large number of sheets, fog in continuous formations of images of low color area percentage in a low humidity environment, and re-transfer in multi-color image formation. Thus, the toner is suitably used in a multi-color image forming system.

A battery cell includes a battery housing case formed with a through hole communicating with an interior space, a hollow rivet, and a seal rubber. The hollow rivet has a seal surface annularly extending outside the battery housing case, and a hollow portion formed with an exhaust port continuous to the inner edge of the seal surface and positioned at the through hole to allow gas in the interior space to flow out through the exhaust port. The seal rubber has a contact unit extending annularly facing the seal surface to press the seal surface and is provided so as to close the exhaust port. The contact unit is formed to project toward the seal surface so as to contact the seal surface at a position away from the inner edge of the seal surface. Such an arrangement prevents an electrolyte leakage over a long period of time.

A method and device for displaying an underwater detection image is provided, in which an ultrasonic signal having a predetermined beam width is periodically transmitted underwater, receives a signal reflected on a detection target object which moves underwater, generates information on the detection target object based on the received signal, and displays the information on a display module. The method includes periodically detecting the detection target object and a position thereof based on the received signal, coupling the same detection target objects by associating the same based on the detection target object and the position periodically detected, and associating a displacement symbol corresponding to a change in a position of the detection target object with the coupled detection target object, and displaying the displacement symbol at the detected position of the detection target object at least on a two-dimensional position coordinates displayed in the display module.

An object is to provide a sebum secretion inhibiting composition and a food or drink product using the same. The present inventors have conducted extensive studies and consequently found that the sebum secretion is inhibited by orally ingesting a collagen peptide, which is hydrolyzed collagen, and provide an oral sebum secretion inhibiting composition comprising a collagen hydrolysate and a food or drink product containing the composition.

A storage system includes a storage and control units. In each of the control units: a relay unit relays access to the storage; an access controller accesses the storage through one of the relay unit in the control unit and the relay unit in another of the control units; and an operational-state controller determines whether or not the relay unit in the above-mentioned another control unit is usable when the operational-state controller detects occurrence of an abnormality in the above-mentioned another control unit, and makes the above-mentioned another control unit transition to a partially-operational state when the relay unit in the above-mentioned another control unit is usable. In the partially-operational state, at least the access controller in the above-mentioned another control unit is not in operation and the access controller in the control unit can access the storage through the relay unit in the above-mentioned another control unit.

A light emitting element mounting substrate that enables a high quality light emitting element package to be readily manufactured with minimal variations in the chromaticity when manufacturing a white LED, a light emitting element package that employs the substrate, and a display device and illumination device that employs this package, are provided. In the light emitting element mounting substrate, at least a light emitting element mounting portion of a surface of a core metal is coated with a fluorescent enamel layer that consists of a fluorescent material-containing glass. In the light emitting element package, a light emitting element is mounted on the light emitting element mounting substrate, and the light emitting element is sealed with a transparent sealing resin.

An alkaline storage battery 1 has: a cathode 2 containing β-type nickel hydroxide and/or β-type nickel oxyhydroxide as a cathode active material; an anode 3 containing an anode active material; and an alkaline aqueous solution as an electrolytic solution 4. The alkaline storage battery 1 is configured to restrain at least part of a crystal structure of the cathode active material from changing due to charging or discharging and to restrain the cathode active material from exhibiting a new diffraction peak at a position that ranges from 8.4 degrees to 10.4 degrees in X-ray diffraction angle 2θ by X-ray diffraction using CuKα-rays. It is preferable that an anion-exchange membrane layer 25 should be provided on a surface of the cathode 2.

An alkaline storage battery has an electrode terminal that is inserted in a penetration hole, and disposed astride an inside of a battery case and an outside of the battery case, and fastened to a hole periphery portion via a packing. The negative terminal has a seal portion that, together with the hole periphery portion, clamps and compresses the packing to liquid-tightly seal the penetration hole. The seal portion includes an annular seal surface located facing the hole periphery portion, and a seal periphery surface located around the seal surface. The seal surface is protruded from the seal periphery surface toward the hole periphery portion. The surface roughness Ry of the seal surface of the negative terminal is 15 μm or less.
