Title: Terminal power supply controller
Inventor: SANO MASAHIKO
IPC: H04M19/08
Filed: 1991-03-14
Abstract: PURPOSE:To provide a terminal power supply controller which can control the power supply of data terminal equipment in accordance with data transmitted from the other station in a packet switching network. CONSTITUTION:Data terminal equipment DTE is connected to an interface circuit IF from the line terminator DCE of a packet switching network PNW and, further, a terminal power supply controller 10 is branched from the circuit IF. The terminal power supply controller 10 transmits packet data after a link is established and, when it receives a power supply closing command, releases the link and, immediately after that, closes the power supply of the data terminal equipment DTE. Then the packet data transmission is relayed by the data terminal equipment and the terminal power supply controller 10 discontinues the transmission and monitors the packet data transmission. When the terminal power supply controller 10 receives a power supply cut-off command, the controller 10 cuts off the power supply immediately after the link is released by the data terminal equipment DTE.

Abstract: PURPOSE:To improve electromagnetic conversion characteristics, traveling property and durability by using the same kind of the material as the lubricating agent and polishing agent used in the uppermost layer of plural magnetic layers as the lubricating agent and polishing agent of the additives to be incorporated into a back coat layer. CONSTITUTION:The plural magnetic layers formed by dispersing ferromagnetic powder into a binder and incorporating the lubricating agent and polishing material as the additives therein are provided on one face on a nonmagnetic base. The same kind of the materials as the lubricating agent and polishing agent used in the uppermost layer of the plural magnetic layers are adopted as at least the lubricating agent and polishing agent of the additives to be incorporated into the back coat layer. The magnetic layer of the upper layer in the double-layer constitution is formed thin in order to improve the electromagnetic conversion characteristics and the amt. of the additives in the magnetic layer (the upper layer) is confined to the extent of not impairing the electromagnetic conversion characteristics in order to improve the traveling property and durability. Such materials are added to the back coat layer. The lubricating agent and polishing agent are replenished from the back coat layer to the magnetic layers in such a manner and the traveling property and durability of the tape are thereby improved coupled with the presence of the above-mentioned agents in the back coat layer.

Abstract: PURPOSE:To obtain a polymer for a resist material having superior resistance to dry etching and suitable for use in the manufacture of an integrated circuit or the like by polymerizing a monomer mixture contg. trialkylsilylmethyl methacrylate as a constituent unit. CONSTITUTION:A copolymer represented by the formula (where A is a repeating unit from an ethylenic unsatd. compound, R is lower alkyl, and X and Y are the mole fractions of the constituent units) is manufactured by polymerizing a mixture of trialkylsilylmethyl methacrylate with a monomer A such as (meth)acrylic ester, a styrene deriv. or divinylbenzene in an org. solvent. Only the monomer mixture may be polymerized. The resulting polymer soln. or molten polymer is put in a solvent which does not dissolve the polymer such as methanol or hexane, and a white powdery polymer is taken out by filtration and vacuum-dried. When the purified polymer is used, a resist film having high resistance to dry etching with oxygen plasma or the like can be formed. The resist film is suitable for the accurate formation of a fine pattern for manufacturing an integrated circuit or a bubble memory element.

Title: Driving voltage applying method for ink jet print head piezoelectric device
Inventor: MIYAMOTO TSUTOMU
IPC: B41J2/045
Filed: 1990-03-01
Abstract: PURPOSE:To obtain a larger displacement quantity of a piezoelectric device with a voltage whose amplitude is the same as a conventional amplitude by specifying electric potential levels V1, V2 to be applied to the piezoelectric device. CONSTITUTION:A piezoelectric device 1 of an ink jet print head is connected with a vibrating plate 2 by an adhesive and the like. Further, the piezoelectric device 1 is polarized in the direction of thickness, that is, in the vertical direction. When a voltage is applied, a dimensional change occurs to the piezoelectric device 1 in the direction of d31. The piezoelectric device 1 whose dimension is changed generates a vertical displacement quantity Y due to a stress relation with the diaphragm 2, so that an ink is permitted to fly by the ink jet print head making use of the displacement. In the voltage applying method, a larger dimensional change comparing with the conventional method can be obtained by applying to the piezoelectric device 1 pulses of the two potential levels V1, V2 which becomes-Vp<V1<0, 0<V2 (Vp...a voltage to generate a polarization inversion). If the dimensional change of the piezoelectric device 1 becomes large, the displacement quantity Y of a piezoelectric transducer itself also becomes large.

The frequencies of the signal wave and the local oscillation wave are mixed by the mixers 2a and 2b by using the non-linearity of the semiconductor element, the mixed waves are synthesized by a 180 deg. synthesizer 6, and the desired output wave is taken out from an output terminal 5. The outputs of the unit mixers 2a and 2b are synthesized by the synthesizer 6, so that the waves whose phase difference is 180 deg. among the waves outputted from the mixers 2a and 2b are synthesized and outputted, and those whose phase difference is 0 deg. are suppressed. Therefore, the local oscillation wave is controlled, and the input wave is outputted as the output wave. Thus, a band stop filter 16 which controls the input wave is provided at the output of the unit mixer.
