Filed: 1994-10-28
Abstract: PURPOSE: To reduce the discrimination time for a digital data signal by allowing a receiver side standard facsimile equipment to make hand-shake with a transmitter side communication equipment and interrupting line connection to the receiver side standard facsimile equipment when a succeedingly sent signal is digital data. CONSTITUTION: When a receiver side communication equipment B generates a ring signal by a call from a transmitter side communication equipment A, a standard facsimile equipment b2 is connected to a line and the facsimile equipment b2 sends back a facsimile control signal (DIS) to the communication equipment A. In the case of facsimile communication by the communication equipment A, the facsimile communication state is set as it is. When the communication equipment A desires digital communication, the interrupt of line is informed to the receiver side. The communication equipment B uses a time between the facsimile communication time and a DIS generating time to discriminate whether or not facsimile communication is made.  After a digital facsimile equipment (DFAX) b3 detects a line interrupt state, the equipment b3 itself makes line connection to make communication with a DFAX equipment a3 of the communication equipment A.

Title: Insulated-gate field-effect semiconductor device
Inventor: YAMADA KOICHI
IPC: H01L21/336
Filed: 1990-10-26
Abstract: PURPOSE:To easily shorten the length of a channel by assigning the opposite conductivity type to the edge of a gate electrode to that of an impurity diffused region for a drain region. CONSTITUTION:The conductivity type of edge 5'' of a gate electrode 5 is set to be the opposite to that of an impurity diffused region 3 for a drain region. That is, if the conductivity type of a doped polysilicon edge 5'' of the electrode 5 is a p type, the conductivity type of the region 3 is an n type. On the contrary, if the conductivity type of the edge 5'' is an n type, the conductivity type of the region 3 is a p type. The doped polysilicon 5'' except the edge 5'' of the electrode 5 may be the same conductivity type as that of the edge 5'', or opposite to it. Accordingly, an electric field effect due to a drain voltage is alleviated. Thus, the length of a channel can be easily shortened.

Title: Treating method and apparatus
Inventor: TOKUNAGA KENJI
IPC: H01L21/306
Filed: 1986-12-08
Abstract: PURPOSE:To enable an object to be treated in various ways and to be treated in a particular manner in a particular part thereof in a treating chamber, by applying light intermittently to the object for heating it to adequate temperatures appropriate for respective treatments each of which is performed by supplying a treating fluid to the object heated to a predetermined temperature within the treating chamber. CONSTITUTION:A semiconductor wafer 3 positioned within a treating chamber is heated by intermittent irradiation of light 11 such as infrared radiation or the like emitted from a flashing light source 9. By changing properly the flashing cycle or duration of one lighting of the light source, the temperature of the semiconductor wafer 3 can be varied rapidly to a desired value. This makes it possible to combine as desired various treating fluids 7 with appropriate temperatures of the wafer 3. Accordingly, various treatments can be performed sequentially within the same treating chamber 1. For example, a cleaning treatment for removing a natural oxide film from the surface of the wafer by means of vapor-phase etching can be followed by the formation of thin film by means of chemical vapor-phase deposition.

Title: N-isopropyl(meth)acrylamide polymer and its production
Inventor: NANBA TAKASHI
IPC: C08F2/38
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To obtain an N-isopropyl(meth)acrylamide polymer easy in controlling its cloud point, and having a sensitivity to e.g. pH, electric potential or salt concentration, adsorbability or the like by including an N-isopropyl(meth) acrylamide unit and cysteamine unit. SOLUTION: This polymer comprises an N-isopropyl(meth)acrylamide unit of formula I (R1 is e.g. H or a 1-4C alkyl), and a cysteamine unit of formula II or its neutralization salt, and it is obtained by polymerizing an ethylenic unsaturated monomer composition containing an N-isopropyl(meth)acrylamide monomer in the presence of cysteamine. A usage of the cysteamine and its neutralization salt pref. lies in the molar ratio (500 to 1) to (10 to 1) of the ethylenic unsaturated group to the unit of formula II. Furthermore, it is preferable to include a unit of formula III (X is NH or C=O; and R2 and R3 are each a 1-4C alkyl) or its neutralization salt because of enabling the polymer to be imparted with the above sensitivity and a high cloud point while allowing it to keep a function derived from the unit of formula I.
