Title: Printing method and document preparing device
Inventor: ICHINISHI TAIICHI
IPC: B41J19/32
Filed: 1994-12-26
Abstract: PURPOSE: To print a document by shifting partly the character strings with every character in the digit direction in a print mode. CONSTITUTION: When a character modification request is received from a keyboard 1 in a print mode, a print position change designation processing part 9 reads the type item of a character modification information setting screen out of a memory 4 and shows it on a display 6 via an editing control part 3 and a display control part 5. Thereby, if a left-set mode is selected by a user, a print position change designation processing part 9 shows a shift reference item of the character modification information setting screen on the display 6 in the same way as the type item. Then a print processing part 10 calculates the number of dots corresponding to the digit width equivalent to a single character and also calculates a print position of the digit direction from the calculated number of bits if the user selects the half of the digit width.  A print control part 7 produces the font data on a designated character code at the calculated print position and then sends this font data to a printer 8 to print the designated character with shift.

Title: Mis transistor
Inventor: MATSUO ICHIRO
IPC: H01L29/78
Filed: 1987-12-18
Abstract: PURPOSE:To obtain a MIS transistor high in operational speed and breakdown strength by a method wherein the impurity concentration of a channel section of a transistor is made higher than that of a semiconductor substrate in contact with a highly concentrated drain region so as to make a gate length short. CONSTITUTION:An N-type source region 12 and an N<+>-type drain region 13 are formed along the surface of a P-type semiconductor substrate 11. An N<->-type drain region 14 is formed making contact with the region 13. A P-type well region 15 is formed inside the substrate 11 near to the region 14. A gate insulating film 16 and a gate electrode 17 are successively laminated on a region 15 between the regions 12 and 14. The region 15 is made to start decreasing in impurity concentration from a part under the electrode 17 toward the region 13. Therefore, a gate length can be short as a sufficiently high drain breakdown strength is retained. By these processes, a MIS transistor high in breakdown strength and operational speed can be obtained.

Title: Cassette loading device
Inventor: MATSUDA TAKASHI
IPC: G11B15/675
Filed: 1989-12-14
Abstract: PURPOSE:To surely inject a cassette even when a lid becomes shut by providing a spring with its arm abutted to a guide pin for opening/closing and which guides the guide pin for opening/closing near a link lever. CONSTITUTION:By the variation of the relative position of a guide pin 8a which moves along a guide hole 6a and a guide pin 26 for opening/closing which moves along a guide hole 31 for closing/opening, a link lever 23 is turned, a release lever 19 is turned interlocking with this, and the lid 1a of a cassette 1 is opened and closed. When the lid comes off the release lever and the lid closes while the lid 1a is opening and closing abutted to the release lever 19, the relative position of the guide pin 8a and the guide pin 26 for opening/closing becomes fixed, but a cassette holder 2 must keep on moving to the insertion position direction of the cassette, so the guide pin 26 for opening/closing is positioned to the relief part 32 of the guide hole 31 for closing/opening against the pressing force of a spring 30. Thus, the cassette is surely injected even when an inconvenience of the lid becoming shut during cassette loading occurs.

IPC: B01D53/22
Filed: 1987-12-22
Abstract: PURPOSE:To produce a hydrogen separating membrane having high durability for long time use at low temp. and having high permselectivity for H2 by plating a thin Pd film on the surface of a heat-resistant porous body, plating further a thin Ag film thereon and then heat-treating the plated product. CONSTITUTION:A thin Pd film is formed on the surface of a heat-resistant porous body such as sintered body of fine ceramic particles, etc., by the chemical plating process, and a thin Ag film is formed further thereon by the chemical plating process. In some case, a thin Pd film is formed further thereon by the chemical plating process, and treated by heating. By this heat-treatment, Pd and Ag are diffused into each other, thus a hydrogen separating membrane comprising an alloy consisting primarily of Pd and Ag is obtd. Deterioration of performance and crack generation are not caused in the obtd. membrane even if it is used for a long time at low temp. of <=300 deg.C, and the permselectivity for H2 is extremely good.

Title: New unsaturated fluorocarboxylic acid chloride
Inventor: TARUMI YASURO
IPC: C09K3/18
Filed: 1992-11-06
Abstract: PURPOSE:To provide a new unsaturated fluorocarboxylic acid chloride, 2,2- difluoro-3-butenoic acid chloride, easily convertible into esters, amides or acid fluorides, to be used for polymers, improving the characteristics of Si compounds. CONSTITUTION:A flask equipped with a stirrer, a thermometer, a condenser and a dropping funnel is charged with 2,2-difluoro-3-butenoic acid and dimethylformamide followed by heating to 40 deg.C; thionyl chloride is then gradually added, through a dropping funnel, to the system. With caution so as not to get too vigorous in the generation of SO2 and HCl gases, the dropping is continued at 40-60 deg.C for 5hr. At the point when gas generation is ceased, the product is distilled off the system at reduced pressures followed by further distillation, thus obtaining the objective 2,2-difluoro-3-butenoic acid chloride with a boiling point of 62-66 deg.C at normal pressures. This new compound is highly easily convertible into derivatives such as esters, amides or acid fluorides, and is capable of obtaining fluorogroup-incorporated polymers by its use as a monomer.

Title: Video tape recorder integrated with portable liquid crystal television
Inventor: TORII HIROYUKI
IPC: H04N5/44
Filed: 1990-11-28
Abstract: PURPOSE:To prevent the consumption of a battery in a non-using state by providing a means to make the power source circuit of a set automatically off by a microcomputer output when a microcomputer judges the non-using state which is continued for more than constant time and operational information from an operation button does not exist. CONSTITUTION:When television broadcasting on the air ends or external input does not exist while the television broadcasting received by a receiving circuit 1 and the picture of a video signal for reproducing inputted to an external signal input terminal 2 are seen by a liquid crystal television 4, since a synchronizing signal does not exist for the output of a video signal processing circuit 3, the output signal of a video synchronization detecting circuit 8 becomes 'LOW'. Then, since a mechanism is in a non-operating state, also the output signal of a mechanical operation detecting circuit 6 becomes 'LOW'. A microcomputer 7 executes judgment that the state is a non-using state and transmits a signal to make a power source switch 5 off automatically when an operation button 9 is not pressed within constant time. Thus, the unnecessary consumption of power generated when a set is not used can be prevented.

IPC: C08K3/34
Filed: 1987-12-21
Abstract: PURPOSE:To improve the durability of a packing material and provide the satisfactory freshness retaining ability over an extended time, by adding a porous mineral consisting chiefly of silica and alumina and a low melting point synthetic resin fiber to paper making or synthetic resin material and softening and coalescing the low point synthetic resin fiber thereto. CONSTITUTION:Paper making or synthetic resin material composing a case 2, mixed with a porous mineral consisting of cristobalite, zeolite, etc. and a low melting point synthetic resin fiber, are subjected to an ultrasonic heat treatment after making and drying the paper. The low melting point synthetic resin fibers of a 10-15mm long curl are added to the material in the almost same proportions by weight. The cristobalite and zeolite, both consisting chiefly of silica and alumina and having number of small pores, are capable of satisfactorily adsorbing the ethylene gas being an aging hormone of foods and ammonia gas associated with the food decaying. Moreover, in addition to the intertwisting of the paper making or synthetic resin material itself produced by the addition of the low melting point synthetic resin fibers, the further intertwisting is produced by the ultrasonic heating, permitting the tensile strength of the packing material along the axes X, Y and Z to increase by several times.

IPC: H01L29/812
Filed: 1987-12-23
Abstract: PURPOSE:To reduce a surface space charge density by forming a delta-doped monoatomic layer on a boundary between the surface of a semiconductor or an insulating film and the semiconductor, the surface or at a position within several atom layers from the boundary. CONSTITUTION:When the number of doner impurities to be ionized by a delta- doped monoatomic layer 105 is equalized to that of the surface level of an active layer 103 to be activated as acceptors, a depletion layer of an intermediate region 107 is completely eliminated, and operated as a preferable FET. Since space charge is not provided on the layer 103, an electric field concentration is not provided between a gate electrode 106 and source, drain electrodes 104. Thus, even if the region 107 has a considerable conductivity, the breakdown strength of the electrode 106 is held high.
