A vacuum heat insulator is provided which includes a vacuum heat-insulated space defined between a pair of spaced outer skin members, a portion of the space closer to one of the outer skin members being set as high-temperature side, with a portion closer to the other outer skin member being set as low-temperature side. A laminate is disposed at the high-temperature side of the vacuum heat-insulated space, and a board having an inorganic material is disposed at the low temperature side. The laminate includes inorganic sheet members and metallic foils with low heat emissivity, the sheet members and metallic foils being alternately laid in plural layers.

An outer peripheral sealing surface of an inner surface of a core plate of a header tank is configured into a loop and extends along an outer peripheral edge portion of the core plate and clamps a packing in cooperation with an outer peripheral end portion of a tank main body of the header tank. A transition section of the outer peripheral sealing surface connects between a primary section and a secondary section, which are located in two different planes, respectively, and the plane of the secondary section is the same as a plane of a boundary portion sealing surface held between two tube connecting surfaces in the core plate.

An electrode of a secondary battery is treated to remove an electrode material adhering to the current collector of the electrode. The electrode is treated by exposing to a stripping agent, which is constituted as an aqueous solution containing at least one of an organic sulfonic acid and derivative thereof, and the electrode exposure to each other to strip the electrode material from the current collector constituting the electrode.

Provided is a method for treating lithium batteries (100) having a positive electrode member (155) comprising an aluminum positive current collector (151) and a positive active material layer (152) containing a composite oxide of lithium and transition metal element positive active material (153) which is fixed to the positive current collector (151). The method includes an acid solution treatment process (step S4) wherein an acid solution, namely aqueous phosphoric acid solution, aqueous carbonic acid water or aqueous hydrogen sulfide, is brought into contact with the surface of the positive active material layer (152) and the positive current collector (151) which constitute the positive electrode member (155), and the positive active material layer (152) is separated from the positive current collector (151), and an oxalic acid treatment process (step S8) wherein the material for treatment (PM) containing metal components originating from the positive active material layer (152) is reacted with aqueous oxalic acid solution.

A mechanical seal M1 that can be installed in a simple procedure and thus simplifies maintenance. The positioning of the stationary seal unit 3 and rotary seal unit 4 is effected by setting spacers 5 fixed on the stopper ring 36. The stopper ring 36 is mounted on the sleeve 34 by engaging connection means 37 which include annular grooves 48 formed in the stopper ring 36, pin engaging holes 49 provided in the sleeve 34, headed pins 51 comprising a pin portion 52 to engage with the pin engaging hole 49 and a head portion 53 which engages with the groove 48 and is relatively movable in the annular groove 48 of the stopper ring in the circumferential direction of the ring 36, but is relatively unmovable in the axial direction, and head lead-in inlets that open the annular groove 48.

Hydrates of N-(4-acetyl-1-piperazinyl)-4-fluorobenzamide, which are stable against heat, light, and humidity, are described. The material is easy to handle under ordinary interior humidity conditions. N-(4-acetyl-1-piperazinyl)-4-fluorobenzamide hydrate is useful as a medicament in the treatment of amnesia and senile dementia.
摘要:
A method of monitoring abnormality of a clock driver in an electronic apparatus having a clock supply unit that supplies a clock signal and a plurality of function executing units to which the clock signal is inputted for executing prescribed functions at an identical clock, wherein each function executing unit is provided with a clock driver which, on the basis of the clock signal, oscillates internally to reproduce a clock signal, includes monitoring cut-off of an input clock signal and cut-off of an output clock signal of the clock driver, and outputting an alarm upon judging that the clock driver is abnormal in a case where the output clock signal has been cut off but the input clock signal has not. Alternatively, the method includes monitoring the phase of the input clock signal and the phase of the output clock signal of the clock driver, and outputting an alarm upon judging that the clock driver is abnormal in a case where the output clock signal has developed a phase shift, which is greater than a prescribed value, with respect to the input clock signal.
摘要:
A horizontal rotary hook has an outer rotating hook body provided with a mounting protrusion protruding from the outer circumference of the side wall thereof and provided with an upper mounting surface and a side mounting surface. A thread catching member is placed movably on the upper mounting surface of the mounting protrusion, the horizontal position of the thread catching member relative to the axis of the outer rotating hook body is determined by using a positioning jig, and then the thread catching member is fixed to the mounting protrusion of the outer rotating hook body by welding. A loop expanding member is joined to the thread catching member so as to stand perpendicularly to the upper surface of the thread catching member and a part of the loop expanding member is fixed to the side mounting surface of the mounting protrusion by welding. Since the horizontal position of the thread catching member is adjustable, the component parts of the horizontal rotary hook need not be formed in a very high dimensional accuracy but the horizontal rotary hook can be assembled with a high accuracy in order to prevent stitch skipping and noise generation, and can be manufactured at a reduced cost.
