Abstract: PURPOSE:To reduce an operating voltage of a field effect transistor and to improve the charge injection efficiency of the transistor by forming an insulating film between a floating gate and the surface of semiconductor in a laminated structure of dioxidized silicon film and a nitrided silicon film of specific thickness. CONSTITUTION:In a transistor in which a floating gate 8 having no conductive coupling with an external circuit is formed in an insulating film interposed between a gate electrode G and the surface of a semiconductor of an insulated gate field effect transistor, an insulating film between the gate 8 and the surface of the semiconductor is formed of a laminated structure of dioxidized silicon film 11 of 20-400Angstrom  and a nitrided silicon film 7 of 50-500Angstrom . For example, the surface of the semiconductor is thermally oxidized to grow a dioxidized silicon film 11 of 20-400Angstrom , a nitrided silicon film 7 of 50-500Angstrom  is covered on the dioxidized silicon film, the nitrided silicon film is thereafter preferably introduced into thermally oxidizing atmosphere.

Title: Disk device
Inventor: HOSHI TATSURO
IPC: G11B27/10
Filed: 1994-04-21
Abstract: PURPOSE:To perform recovery processing without feeling a sense of incongruity at the time of turning on/off a power source at low cost without complicated processing operation by stopping an optical head in a position at the time of turning off the power source and resuming reproducing from this position at the time of turning on the power source. CONSTITUTION:When an Acc switch 11 is turned off, a disk D is stopped, while a feed motor M2 for the optical head H is also stopped, and the optical head H is stopped in its position. In addition, a lock of a servo control part 7 is released, and contents held in a memory 5 are erased to release TOC data, and also subcode data of the memory 5 are erased to make a changeover to a standby mode. When the Acc switch 11 is turned on, the position of the optical head is slightly moved back by controlling the feed motor M2, and reproducing operation is resumed under an operation mode without using TOC. At this time, the subcode data are sent from a decoder 2 to the memory 5 to set that music number under the reproduction. By this method, you can listen to a CD at the resuming time after interruption by simple control processing without feeling a sense of incongruity.

Title: Ink-jet recording sheet
Inventor: OTA YOSHIHIKO
IPC: B41M5/52
Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To clearly record a full color image by using a printer and a plotter and to make ink drying properties fast and to make spreading of an image less by making a coating layer just above a substrate to be a solvent-base coating agent and a coating layer of the outermost surface layer to be a water- base coating agent. SOLUTION: As a tracing paper for obtaining the second original drawing exhibits poor dimensional stability, tear strength and water resistance and especially, remarkably poor processability such as coating operation, a solvent- base coating agent is applied on the first coating layer being a layer just above a substrate. This first coating layer has water resistance with good adhesiveness with the tracing paper and the second coating layer. On the first coating layer thus obtd., an ink receiving layer contg. a silica and a hydrophilic polymer compd. is applied. For a purpose for providing an applicability for the second original drawing paper, a silica with a mean particle diameter of 3.0-10.0μm is used.  When such a silica that has a mean particle diameter exceeding this value is used, good transparency is not obtd. and clarity of an image is inferior and spreading occurs and when it is smaller than that, the transparency decreases.

Filed: 1983-06-14
Abstract: PURPOSE:To perform partial erasure accurately even in a system equipped with plural graphic input devices by deciding on whether the partial erasure is carried out or not on the basis of input starting-point information and input ending-point information in coordinate value information on a figure. CONSTITUTION:The system is actuated and coordinate value information on a figure inputted on the pen input surface 103 of a graphic input device 100 is extracted and sent out to the arithmetic circuit 105 of a processor 101 through a signal line 107. Then, the circuit 105 stores coordinate value information on an input starting point in a video memory 106 with a partial erasure indication signal, and coordinate value information on a point which is determined as an input ending point because the pressure decreases below a threshold value is inputted in an exclusive-use address of the memory 106. Then, the circuit 105 reads the pieces of coordinate value information on the input starting point and input ending point out of the memory 106 to calculate the distance L between those two points, and decides on whether the partial erasure is performed or not on the basis of the distance. Thus, the system equipped with plural devices performs the partial erasure accurately.

Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To efficiently remove a remaining liquid semiconductor material having high toxicity by evacuating the inside of piping including a container in which the liquid semiconductor material remains to a vacuum state and filling an inert gas therein, then discharging this inert gas from the inside of the piping. SOLUTION: The vacuum evacuation in the piping route is executed by opening a valve 31.

Again after standing-by for a specified time, the valve 33 is closed and the valve 31 is opened to evacuate the inside of the piping route. The dilution of the liquid semiconductor material by the inert gas filling, the discharge of the inert gas containing the liquid semiconductor material by the vacuum evacuation and the vaporization of the liquid semiconductor material are repeated by repetition of a series of these operations exclusive of the leak check by the first vacuum evacuation, by which the efficiency of removing the liquid semiconductor material may be enhanced. The time for removing the liquid semiconductor material may be shortened.
