IPC: H01L21/331
Filed: 1978-01-17
Abstract: PURPOSE: To obtain a lateral transistor which features a high emitter-earthed current amplification factor and good frequency characteristics by forming a high impurity density region which is the same conducting type as the base different from the buried layer right under the emitter within the base region or right under the base draw-out impurity region.  
     CONSTITUTION: N + -buried layer 13 is formed through diffusion on P-type Si substrate 11, and N-type layer 12 to become the base region is epitaxial-grown on the entire surface with its surface covered with SiO 2  film 14. Then the window is drilled to film 14 in a smaller size than the emitter region and the base draw-out high density impurity region and enclosing these regions completely in order to inject the impurity ion. Thus, N + -buried region 15 is formed through the heat treatment. After this, the window is drilled again at the emitter and collector forming regions to form P-type emitter region 16 and P-type collector region 17 through diffusion with base electrode draw-out region 18 added. Then Al wiring 19 is coated to each region to form a lateral transistor.

IPC: H04Q3/52
Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To reduce the cost of an exchange by connecting a subscriber line concentration part to subscriber lines the number of lines of which is equal to the number of subscribers, and scanning the subscriber lines and the arbitrary subscriber circuits the number of circuits of which is smaller than the number of the subscriber lines by a subscriber line concentration control part. SOLUTION: When a subscriber A makes a cell, the call is detected by a subscriber line concentration control part 12 which is already executing scanning, a subscriber line concentration part 11 and an arbitrary subscriber circuit group 13n. The subscriber line of the subscriber A is connected to the subscriber circuit group 13n and a subscriber information multiplex part 14, and the operation of calling an exchange-side is started. When the call is made to a subscriber B connected to a subscriber corresponding device 10, the subscriber concentration control part 12 gives an instruction to connect the subscriber B to the arbitrary subscriber circuit group 13n and the subscriber information multiplex part 14.  In either case, the subscriber concentration control part 12 does not connect or cut the new subscriber to/from the subscriber circuit group 13n and the subscriber information multiplex part 14, until the call is terminated. The connection of a subscriber line 20n is released after the call termination.

Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To omit unnecessary screen display through skipping and to improve the operability by a user by arranging skip keys on respective guide pictures prompting the user to input while sequentially displaying the specific guide pictures. SOLUTION: When the user sets communication, 1st to 5th guide pictures are sequentially displayed. For example, the name, etc., of a destination are inputted to a text box 'transmission destination' on the 1st picture and the FAX number of the destination is inputted to 'FAX number'. Then when 'attachment of a cover' is set ON, a 'cover preview' button is made effective and a cover preview picture is displayed. When a 'transmit' button pressed, the communication setting is completed. When the 'attachment of a cover' is OFF and 'Internet FAX' is ON, the display is updated to the 4th picture and when OFF, the display is updated to the 5th picture. That is, the 2nd and 3rd pictures are guide pictures for cover setting, and so they are skipped when a cover is not attached.

Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a separate type air conditioner in which sufficient cooling capacity can be sustained at low cost through a simple arrangement without requiring a controller on the outdoor unit side while preventing an indoor heat exchanger from freezing even when the outer air temperature is low and cooling performance can be enhanced when the outer air temperature is low.

Title: Division device of rush
Inventor: FURUKAWA KAZUO
IPC: A01C11/02
Filed: 1990-01-12
Abstract: PURPOSE:To always make rotary tools act on a next mother stock in a state of the tool before cutting free from small stubs and fine cut root parts after cutting by equipping a division device of rush with a rotary scraper which comes into space between adjoining rotary tools after division and scrapes away divided small stubs and rotation direction of the rotary scraper in a direction opposite to that of the rotary tools. CONSTITUTION:A rotary scraper 15 comes into space between rotary tools 6. Therefore, even if small stubs and fine cut root parts after cutting are entangled at intervals of the rotary tools 6, the rotary scraper 15 removes the sandwiched small stubs and the fine cut root parts. Moreover, since the rotary scraper 15 is revolved in a direction opposite to that of the rotary tools 6, the small stubs, etc., are scratched off by high relative velocity against the rotary tools 6 and scraping power can be enlarged without much increasing revolving speed of the rotary scraper 15. Consequently, phenomena wherein the rotary tools 6 in a state of entanglement with the small stubs and the fine cut root parts after cutting will act on the next mother stock and the cut small stubs and the fine cut root parts are released unexpectedly before or in the middle of cutting action on the next mother stock can be prevented before they happen.

Abstract: PURPOSE:To attain high-speed access to a file by arranging plural files of the same user at a position near a disk device, and issuing an instruction to move a head to a head driving part based on a user recognizing number. CONSTITUTION:A recognizing number judging part 2 judges the consistency between a device recognizing number sent from a host and the present device recognizing number. When they are inconsistent, the part 2 instructs a judging part 3 to seek a magnetic head in a storage area corresponding to the device recognizing number. The judging part 3 obtains the position to move the magnetic head 9 based on the device recognizing number sent from an interface control part 1 and the information of storage area managing table 4, and issues the instruction to the head driving control part 5. Consequently the magnetic head 9 moves to the target storage area on a disk 6 of the magnetic disk device. Thus the plural files can be held near the disk device at every device recognizing number.
