Title: Semiconductor integrated circuit, liquid crystal display device and opposite polarity voltage generating circuit
Inventor: OBUCHI ATSUSHI
IPC: H03K17/687
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit having satisfactory operability with respect to a restrictive condition using voltages where voltages of positive and negative polarities are absolutely equal. SOLUTION: A switching part 40 makes a capacitor 60 to be charged with a positive high voltage VLCD and a reference voltage VM in the first state of timing signals CP1, CP2 and impresses the VM on the storage electrode of one side of the capactor 60 instead of the voltage VLCD in the third state of the timing signals. The storage electrode of other side is connected to a smoothing capactor connection terminal 401 and a third voltage VEO having a polarity opposite to that of the first voltage is formed on the electrode based on a second voltage. Since storage electrode terminals 402, 403 are made to be in high impedance states in the second state, the leakage of charged electric charge is not generated in a transition period from the charging operation to an output operation.  The third voltage becomes a polarity opposite to that of the first voltage and the absolute value level of the third voltage is brought near that of the first voltage.

Abstract: PURPOSE:To provide the smooth jam processing by permitting a jam generation place to be confirmed by eyes, by opening a guide means and releasing the pressure supplied from a separating means, in interlocking with the opening of the upper part unit of an image forming device in the half-divided constitution. CONSTITUTION:When a transfer material 13 stops at a part of a transport passage because of a certain reason, an upper part unit 1 which is axially supported on a lower part unit 8 is opened in an crocodile clip form by a hinge 16. Then, a U-turn guide part constituted of a U-turn guide 4 and a link part 3 is opened by a projection part 2 formed on the upper part unit 1. One edge of the U-turn guide 4 is in a pulled state by a lower part unit 8 by a pulling spring 17, and the spring 17 acts in the extension direction by the projection 2 formed on the upper part unit 1. In this case, a pad supporting plate 18 pressed by the U-turn guide 4 is opened, having the supporting plate 18 as turning center, by the return force of a pad spring 7 in a compressed state, and the separating pad is separated slightly from a paper feeding roller 5. Accordingly, the jam processing can be carried out easily.

Title: Structure of semiconductor epitaxial crystal
Inventor: HINO ISAO
IPC: C30B29/40
Filed: 1989-12-25
Abstract: PURPOSE:To obtain a maximum possible energy gap in an average composition of a compound semiconductor mixed-crystal epitaxial film by a method wherein different bonding lengths of a group III element and a group V element are provided, their composition is changed in a specific cycle in the formation direction of a film and a definite composition is provided as an average of the whole. CONSTITUTION:An epitaxial film having a definite composition is structured in such a way that it is composed of a pluralistic mixedcrystal compound semiconductor of a group III element and a group V element having different bonding lengths and that its composition is changed in a cycle of about 10Angstrom  or lower in the formation direction of the film. That is to say, when, in the case of GaInP, the composition of raw-material atoms is changed in the growth-layer direction on each growth surface, a spontaneous superlattice cannot be maintained in the growth-layer direction; many interfaces in which Ga has been replaced by In are formed in the growth-layer direction; the arrangement of Ga and In on a sublattice of the group III element becomes disordered. Thereby, a maximum energy gap which can be expected from an average composition of their mixed crystal can be obtained irrespective of a growth method or a growth condition.
