A semiconductor device sealed with mold resin is disclosed. The device includes a semiconductor substrate having a main surface and an element formed on the main surface of the semiconductor substrate. A stress buffering film for protecting at least the element from stress of the mold resin is provided on the semiconductor substrate so as to cover at least the element. The entire semiconductor device is covered and sealed with mold resin. The stress buffering film is formed of organo-silicone ladder polymer having a hydroxyl group at its end. In the semiconductor device, water does not get into an interface of the stress buffering film and the underlying substrate, resulting in an enhancement of the moisture resistance of the semiconductor device.

It is an object of the present invention to provide a recording ink which contains at least a pigment, a dispersant, a water-soluble solvent, a wetting agent and water, wherein the pigment contains at least one of diketopyrrolopyrrole red pigment and phthalocyanine green pigment in order to obtain a recording ink and ink set which excel in discharge stability with no head clogging during printing and can obtain high quality images with good color tone on the regular paper as well as on an exclusive recording paper; and ink cartridge, ink record, inkjet recording apparatus and inkjet recording method which utilize the recording ink and ink set respectively.
摘要:
A magnetic sensor is constituted using magnetic sensor chips mounted on stages supported by interconnecting members and a frame having leads in a lead frame. Herein, the stages are inclined upon plastic deformation of the interconnecting members. When the frame is held in a metal mold and the stages are pressed, the interconnecting members are elastically deformed, so that the magnetic sensor chips are bonded onto the stages placed substantially in the same plane and are then wired with the leads. Thereafter, the stages are released from pressure, so that the interconnecting members are restored from the elastically deformed states thereof. When the magnetic sensor chips are combined together to realize three sensing directions, it is possible to accurately measure three-dimensional bearings of magnetism, and the magnetic sensor can be reduced in dimensions and manufactured with a reduced cost therefor.

摘要:
A treating liquid composition containing fine particles being so configured that their dispersion is kept or broken by an external factor such as contact between substance or ultraviolet irradiation, and a recording liquid composition containing a colorant being so configured that its dispersion or dissolution is kept or broken by the external factor are ejected separately onto a recording medium by ink-jet system. Droplets of the treating liquid composition and of the recording liquid composition are brought into contact with each other to cause a condition change such as a pH change or solubility change. The fine particles and the colorant aggregate separately without being substantially mixed with each other. This ink set produces a deep, colorful, sharp and glossy print in exact accordance with an original while effectively preventing feathering and color bleed on whichever of absorbable recording media and nonabsorbable recording media.

A testing system for voice system equipment in a switchboard includes a testing maintenance terminal for inputting telephone number information of an ordinary subscriber's telephone that is to be designated as a maintenance party telephone. The testing maintenance terminal can be a testing maintenance terminal of a general-purpose information processing unit. A call processing block inside a control unit of the switchboard includes a test accepting module for accepting the telephone number information from the testing maintenance terminal and for transmitting a call message to a call control module, in addition to the call control module and a translation module. Therefore, when the telephones number information of the ordinary subscriber's telephone designated as the maintenance party telephone is inputted from the testing maintenance terminal, the call control module and the translation module execute an emulation processing for the call connection processing to the ordinary subscriber's telephone designated as the maintenance party telephone in accordance with the call message transmitted from the test accepting module, in the same way as the ordinary call connection processing. Consequently, various tests can be conducted by using the ordinary subscriber's telephone as the maintenance party telephone for the test of the voice system equipment of the switchboard.
摘要:
A combination tool exchanger and storage device adapted to be fitted to a die cutter for exchanging and storing a plurality of profiled cutter dies each having a cutter blade of a different configuration. The die cutter is for cutting a sheet-like material by urging the sheet-like material against a selected one of the profiled cutter dies retained within a cutter die mounting chamber. The combination tool exchanger and storage device includes retaining arms for holding one of the profiled cutter dies so as to confront a first entrance leading to the cutter die mounting chamber and for sliding the profiled cutter die horizontally towards the cutter die mounting chamber, a cutter die storage chamber disposed above or below the die cutter, and an elevator unit for selectively driving the retaining arms between a first position aligned with the first entrance leading to the cutter mounting chamber and a second position aligned with a second entrance leading to the cutter die storage chamber.
