Abstract: PROBLEM TO BE SOLVED: To provide a bidirectional interface circuit (bidirectional buffer circuit), which is provided with an output circuit that drives the output by means of an N-type MOS transistor only and an input circuit composed of a P-type MOS transistor and an N-type MOS transistor and on which IDDQ tests can be carried out effectively, by interrupting the propagation of intermediate-potential signals even when its outside output terminal incapable of swinging fully to its internal power supply voltage. SOLUTION: In an output mode, in which an enable signal EN is set at 'H' level, an output data signal D in the preceding stage of an output circuit 10 is supplied to an input section 21, by setting one buffer gate 25 in an input selector section 23 to a conducted state. The supply of an intermediate-potential signal outputted to an outside output terminal 101 via an output drive section 12 to the input section 21 is inhibited by setting the other buffer gate 24 in a non-conducted state.

Title: Water ink
Inventor: NAKAGAWA KAZUYA
IPC: C09D11/00
Filed: 1980-02-29
Abstract: PURPOSE: To provide water ink which gives handwriting with excellent water resistance, containing a salt of a basic dye and an anionic surfactant, an ethylene oxide addition type surfactant, a water-soluble org. solvent and water.  
     CONSTITUTION: There is provided an ink containing a salt of a basic dye and an anionic surfactant, an ethylene oxide addition type surfactant, a water-soluble org. solvent and water. The reason why water resistance of the ink is improved may be than a salt is formed from the basic group of the basic dye and the acidic part of the anionic surfactant, and thus the ink is made difficultly soluble or insoluble and exhibits hydrophobicity, whereby water resistance is improved. Said anionic surfactant is used for the purpose of improving water resistance. said ethylene oxide addition type surfactant is used as a solubilizer. Said water-soluble org. solvent has compatibility with water and is used as an auxiliary.

Title: Galvanized steel plate with superior corrosion spalling resistance
Inventor: HIROSE YUUSUKE
IPC: C23C2/06
Filed: 1981-02-24
Abstract: PURPOSE: To enhance the corrosion spalling resistance of a galvanized steel plate by forming an Fe-Zn alloy layer having a specified thickness or above as the alloy layer in the galvanized layer which is in contact with the steel as the base metal of the steel plate.  
     CONSTITUTION: By heating the galvanized layer of a galvanized steel plate coated with zinc or a zinc alloy or reducing the Al content of a galvanizing bath, mutual diffusion between the layer and the steel as the base metal is facilitated to form an Fe-Zn alloy layer having ≥0.2μm average thickness in the galvanized layer. Thus, even if intergranular corrosion proceeds from the zinc layer side, the propagation can be stopped by the Fe-Zn alloy layer, and corrosion spalling is prevented.

Title: Pulse width adjusting system
Inventor: NAKAHARA TAKASHI
IPC: H03K5/04
Filed: 1986-02-06
Abstract: PURPOSE:To obtain an optional pulse width without waveform distortion due to mismatching of a delay element by adjusting a reference voltage to a CML or an ECL circuit. CONSTITUTION:In applying a reference voltage 102b higher than a reference voltage 102a to a reference terminal 102, an output voltage 103b is outputted. This is because a trailing edge reaches the reference voltage 102 earlier than the output voltage 103b by a time DELTAt and the lading edge reaches the reference voltage 102 slower by the time DELTAt, then the pulse width W2 is wider than pulse widths W0, W1 by 2DELTAt. In applying a reference voltage 102c lower than the reference voltage 102a to the reference terminal 102, an output voltage 103c is obtained. Since the trailing edge reaches the reference voltage 102c in comparison with the arrival of the output voltage 103a by a time DELTAt and the lading edge reaches the reference voltage 102c earlier by the time DELTAt, the pulse width W3 is narrower than the pulse widths W0, W1 by 2DELTAt.
