A chromatic dispersion generating apparatus of the present invention comprises a VIPA plate capable of emitting an incident light to different directions according to wavelengths, a three-dimensional mirror reflecting the light of respective wavelengths emitted from the VIPA plate at a previously set position to return them to the VIPA plate, and a control section that controls a position of the three-dimensional mirror and the temperature of the VIPA plate. The control section computes a target position of the three-dimensional mirror and the target temperature of the VIPA plate, which correspond to an arbitrary wavelength and a chromatic dispersion value, based on data relating to positions of the three-dimensional mirror corresponding to a plurality of chromatic dispersion values of a specific wavelength and a chromatic dispersion slope value, and data relating to the temperatures of the VIPA plate corresponding to a plurality of dispersion values for respective wavelengths on a predetermined wavelength grid and a wavelength temperature coefficient, which are stored in a storage circuit, to optimize the computed target position and the computed target temperature. As a result, it becomes possible to generate the chromatic dispersion with high accuracy at an arbitrary wavelength.

A nonaqueous secondary battery 10 of the invention has an active material compound layer 14 deposed over at least one face of a collector 12 made of metal foil and is equipped with a positive electrode 11 having a portion 13 in a part of which metal is exposed. The positive electrode 11 together with the exposed-metal portion 13 faces a negative electrode 17 through an interposed separator 23, and on that part of the exposed-metal portion 13 that faces the negative electrode 17 through the interposed separator 23 there is formed a protective layer 16 made of a material whose electronic conductivity is lower than that of the metal and which moreover is non-insulative. With such nonaqueous secondary battery 10, should part of an electrode pierce the separator and contact with the other electrode, the battery will be gently discharged, thereby averting abnormal heat generation by the battery and additionally enabling the battery's abnormality to be sensed by the equipment via the fall in battery voltage. Thus, there is provided a nonaqueous secondary battery of excellent safety that can prevent abnormal heat generation due to a short circuit caused by burr, powder or the like piercing the separator.

摘要:
A sealed battery has a generator element enclosed within an external casing. An opening in the external casing is covered by a closure cap in which an injection hole for injecting electrolyte is provided. The injection hole is sealed using a sealing plug which is composed of a support member that is fixed on a surface of the closure cap so as to cover the injection hole and a plugging member that is at least partially formed of an elastic material and is supported by the support member so as to plug the injection hole. The plugging member is formed of an elastic material and is pressed into the injection hole by the support member. As a result, an airtight seal can be easily and securely achieved for the injection hole. The support member can be made large to facilitate handling, thereby reducing the likelihood of the sealing plug being improperly supplied during attachment to the injection hole.

The outside edges of a sealing plate are weld attached to close off an opening in a metal case of a prismatic battery of this invention. The sealing plate has an electrode rivet which passes through an electrode hole and sandwiches an insulating gasket to attach in an electrically insulating fashion. The battery case houses an electrode group with either its positive or negative electrode plate connected to the electrode rivet. The sealing plate has a periphery region or reinforcement rib which is formed thicker than the rivet region where the electrode rivet attaches, and the outside edges of this reinforcement rib are weld attached to the case.

摘要:
A radiant gas heating apparatus of the present invention includes a cylindrical member of a porous ceramic material adapted to be heated by radiation, and a flow passageway which directs gas radially through the pores of the ceramic material from one cylindrical surface of the cylindrical member to the other cylindrical surface thereof. A steam electrolyzing apparatus of the present invention includes a light focusing section having a porous ceramic member disposed within a transparent light-receiving section vessel, an electrolyzing cell having an oxygen electrode and a hydrogen electrode disposed on inner and outer surfaces of a cylindrical electrolyte, and a heat-insulating vessel covering the electrolyzing cell. In the steam electrolyzing apparatus, after low-temperature gas has passed through the space between the porous ceramic member and the light-receiving section vessel, the gas passes through the porous ceramic thereby being heated. The operation can occur under a pressurized condition because the mechanical strength of the light-receiving section vessel is not degraded as it is kept cool by the low-temperature gas flowing in the flow passageway.
