A cover body includes: a multi-color molded body including a first resin portion having a gate mark on an outer surface thereof, and a second resin portion having a color different from a color of the first resin portion and adhering to the outer surface of the first resin portion to cover the gate mark. An outer surface of the second resin portion includes a stepped portion that overlaps with the gate mark.

Cover body

A resin molded product () includes a resin molded product main body (), and a protrusion () integrally formed with the resin molded product main body () and protruding from the resin molded product main body (). At injection molding of the resin molded product (), molten resin flows through a portion (C-) corresponding to the protrusion () in a cavity (C) defined by a pair of molds (). A concave portion () is formed on a rear side of the protrusion (), and a bulging portion () having a hollow bag shape is formed on a front side of the protrusion ().

Resin molded product and method for producing resin molded product

An alkyl phenyl sulfide derivative represented by the general formula [I] or an agriculturally acceptable salt thereof, and a pest control agent containing the derivative or the salt as an active ingredient. [in the above formula, Ris, for example, a C&#x2dc;Calkyl group which is mono- or poly-substituted with halogen atom; Ris, for example, a halogen atom or a C&#x2dc;Calkyl group; Ris, for example, a hydrogen atom or a halogen atom; and Ris, for example, a hydrogen atom or a C&#x2dc;Calkyl group.] The derivative or the salt has an excellent pest control effect.

A vehicle lamp includes a lamp body having an opening, a resin cover attached to the opening to form a lamp chamber together with the lamp body; and a light source disposed inside the lamp chamber to irradiate light through the resin cover. The resin cover includes a design surface portion, and a peripheral edge portion surrounding the design surface portion. The peripheral edge portion includes a gate mark, and a thick-walled portion having a greater wall thickness than the other part of the peripheral edge portion and extending from the gate mark toward the design surface portion.

The present invention provides a portable power source comprising a fuel cell generating electricity using hydrogen as fuel, a hydrogen storage unit filled with hydrogen absorbing alloy for supplying hydrogen to the fuel cell, a case enclosing the fuel cell and hydrogen storage unit, and a lid for sealing a part of the case when the portable power source is not in use, wherein the lid seals a surface of the case on which at least one air inlet for taking in the air necessary for the fuel cell to generate electricity and a reactant gas outlet for exhausting reactant gas produced by the generation of electricity are formed.

Portable power source

The present invention discloses a preservation device for lead storage battery comprising: a lead storage battery including at least one negative plate, at least one positive plate, at least one separator between said negative and positive plates, an electrolyte holdingly impregnated by said negative & positive plates and said separator and limited in amount such that substantially there is no electrolyte liberated from said negative & positive plates and said separator, and external terminals having one ends respectively connected to said negative and positive plates and the other ends exposed to the outside of the lead storage battery vessel; and an impedance means connected between said external terminals of said lead storage battery during its preservation. Such preservation device permits to prevent a battery preserved in such device from being decreased in capacity without requiring troublesome maintenance such as supplementary charging at regular intervals, even if it is preserved for a long period of time.

Preservation device for lead storage battery

Electrophotographic photosensitive element using zinc oxide in a photosensitive layer thereof formed in conductive support are described. Zinc oxide is used in combination with polycarbonate binder and a compound of the specific type. The compound is represented by the formula ##STR1## in which R.sub.1, R.sub.2, R.sub.3 and R.sub.4 independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, a cycloalkyl group, an alkenyl group, or an aryl group, R.sub.5 and R.sub.6 independently represent a hydrogen atom, a substituted or unsubstituted alkyl group, a cycloalkyl group, an alkenyl group, a cycloalkenyl group, or an aryl group, R.sub.7, R.sub.8, R.sub.9 and R.sub.10 independently represent a hydrogen atom, a hydroxyl group, a substituted or unsubstituted alkyl group, a cycloalkyl group, an alkenyl group, an aryl group, an alkoxy group or an amino group. Optionally, R.sub.5 and R.sub.6 may jointly form a saturated or unsaturated hydrocarbon ring having from 3 to 10 carbon atoms.

Electrophotographic photoconductive elements

A lead acid battery comprising: a positive plate; a negative plate having higher capacity than said positive plate; a separator interposed between said plates; and an electrolyte, said plates and said separator being impregnated with said electrolyte, the amount of said electrolyte being limited so that a free electrolyte is not substantially present therein, the theoretical capacity of said positive plate being more than 2.5 times as much as the theoretical capacity of said electrolyte, and thus having an excellent discharge storage property; and a method of storing the retainer type lead acid batteries including above battery to improve the discharge storage property comprising permitting said battery to stand under such a condition that a load is connected between said positive and negative plates when said battery is allowed to stand after the discharge has been finished.
