摘要:
Proposed is a powder of ytterbium phosphate having a non-stoichiometric phosphorus to ytterbium molar ratio of 1.08 to 2.0 and having a specified average particle diameter and specified diameter of the crystallites forming the particles. The powder is useful as an infrared-absorbing pigment in a printing ink invisible to naked eyes but detectable by an infrared detecting means for printing of stealth bar code patterns. The ytterbium phosphate powder can be prepared in a convenient and inexpensive method utilizing the precipitation reaction by mixing an aqueous phosphoric acid solution and ytterbium salt solution under specified conditions followed by calcination of the precipitates at a specified temperature and pulverization of the calcined precipitates to give the specified average particle diameter.

A protection element is provided which is capable of stably retaining a flux on a soluble conductor at a predetermined position, enabling a speedy and precise blowout of the soluble conductor in the event of an abnormality. This protection element includes: a soluble conductor 13 which is disposed on an insulation baseboard 11 and is connected to a power supply path of a device targeted to be protected, to cause a blowout by means of a predetermined abnormal electric power; a flux 19 which is coated onto a surface of the soluble conductor 13; and an insulation cover 14 which is mounted on the baseboard 11 with the soluble conductor 13 being covered therewith. In addition, the protection element is provided with a protrusive stripe portion 20 which is formed on an interior face of the insulation cover 14 in opposite to the soluble conductor 13 and in which a stepped portion 20a for retaining the flux 19 is formed at a predetermined position while in contact with the flux 19. The soluble conductor 13 has a hole portion 13a at which the flux 19 is retained.
摘要:
In a method for producing an electronic component device, a heat bonding step is performed in a state in which low melting point metal layers including low melting point metals including, for example, Sn as the main component, are arranged to sandwich, in the thickness direction, a high melting point metal layer including a high melting point metal including, for example, Cu as the main component, which is the same or substantially the same as high melting point metals defining first and second conductor films to be bonded. In order to generate an intermetallic compound of the high melting point metal and the low melting point metal, the distance in which the high melting point metal is to be diffused in each of the low melting point metal layers is reduced. Thus, the time required for the diffusion is reduced, and the time required for the bonding is reduced.

A thermionic converter includes an emitter electrode and a collector electrode. The emitter electrode includes a P-type diamond semiconductor layer doped with a P-type impurity. The emitter electrode is configured to emit a thermion from the P-type diamond semiconductor layer when heat is applied from an external power source. The collector electrode includes an N-type diamond semiconductor layer doped with an N-type impurity. The N-type diamond semiconductor layer opposes the P-type diamond semiconductor layer and is located at a predetermined distance from the P-type diamond semiconductor layer. The collector electrode is configured to receive the thermion emitted from the emitter electrode at the N-type diamond semiconductor layer.

摘要:
A control section of an IRD sends an identification start request to a digital bus via a digital input/output terminal. The control section generates an identification display message by controlling an identification display message generation section, makes a superimposition section superimpose the identification display message on an analog video signal, and outputs a resulting signal via an analog output terminal. An information input apparatus allows a user to identify an input terminal connected to the output terminal of the IRD among a plurality of input terminals of the self apparatus by reproducing the identification display message and presenting it to the user.
