Title: Analog/digital converting system
Inventor: TANI YASUNORI
IPC: H03M1/12
Filed: 1990-11-07
Abstract: PURPOSE:To simultaneously obtain plural digital signals by dividing the frequency of digital signals obtained by A/D conversion performed by using a frequency corresponding to the common multiple of plural prescribed frequencies of a single clock as a sampling frequency into plural prescribed frequencies. CONSTITUTION:Inputted analog signals are converted into digital signals by means of an A/D converter 10 at a single sampling frequency corresponding to the prescribed frequencies of a clock 1. The output of the converter 10 is limited in signal band by means of digital filters 11 and 12 and becomes digital outputs 1 and 2 of sampling frequencies thinned at prescribed ratio by means of D-type flip flops (D) 13 and 14. Therefore, plural digital signals are obtained simultaneously with a single clock and single A/D converter.

Filed: 1987-12-01
Abstract: PURPOSE:To plan simplicity and short time of preliminary correcting work by obtaining the coordinate of an X-axis index point and a Y-axis index point observed from the side for controlling an electron beam irradiating point and making the control of the side for controlling the electron beam irradiating point a specified coordinate by the movement of an XY dynamic mechanism and the scan of the electron beam. CONSTITUTION:The coordinate axis of XY control for controlling an electron beam irradiating point is made X0Y0 axis, when the coordinate of a center point of a mark 21, namely the coordinate of an origin is made (0, 0) by the movement of a holder 2 and the scan of an electron beam 4 by an XY dynamic mechanism 3, the coordinate of a center point of a mark 22 at the coordinate X0Y0, namely the coordinate (Xx, Yx) of an X-axis index point and the coordinate of a center point of a mark 23, namely the coordinate (Xy, Yy) of a Y-axis index point is obtained. An XY control program receiving the information of the coordinate (X, Y) from a memory in which a piece of exposing pattern information is recorded controls so as to make the irradiating point of the electron beam 4 the point of the coordinate (X+(Xy/ Yy)Y, Y+(Yx/Xx)X) at X0Y0 coordinate by incorporating the data. Since the irradiating point matches the point of the coordinate (X, Y) at XY coordinate, desired correction is performed.

After all pages are received and stored, the central processing section 3 checks a function of a pattern transfer destination terminal equipment based on management information of a contract terminal equipment or the like, compares number of picture elements per line of the destination terminal equipment with a picture element number per line of the received pattern so as to decide how many numbers of the received patterns linked laterally are displayed on the destination terminal equipment. If the lateral connection of m-patterns is possible, the connection of m-patterns is informed to a page connection section 5, a 1st block of m-patterns from the head is read sequentially from the large capacity storage section 4 and transferred to the page connection section 5. Thus, the patterns are connected laterally and displayed, and the listing performance is improved and the quantity to be used of the paper is saved.

IPC: H04L12/28
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To reduce the wait time from occurrence of a transmission request till actual transmission. SOLUTION: Each buffer section 10 (N) stores fixed length data 17 (N) sent from a corresponding terminal T (N) and sends the data according to a scheduled transmission time by a scheduler 12. Furthermore, each buffer section 10 (N) stores one set of fixed length data 17 (N) or over, then sets a transmission request signal 14 (N) to be active. When the plural signals 14 (N) are simultaneously active, an encoder 11 selects any of them according to prescribed priority and selects it when the signal 14 (N) of any of them is set active. The shceduler reserves a transmission time of the buffer section 10(N) every time the signal 14 (N) is selected. The reservation is made in such a way that the transmission interval of the fixed length data 17 (N) is not less than the allowable minimum data transmission interval.

Filed: 1987-12-03
Abstract: PURPOSE: To accurately operate, to improve safety and reliability and to improve assembling property by arranging a temperature sensing element and a an overheat preventing device adjacent to the outer side surface of an evaporating room so as to speedily catch the overheat of an equipment. CONSTITUTION: A temperature sensing element 5 detecting the temperature of a base 1 is fixed to the lower side or the upper side of a fixing member 4 at a position adjacent to the evaporating room 3, and the overheat preventing device 6 is similarly fixed to the member 4. Since water is supplied to the room 3 at the time of steam-ironing, the element 5 can detect lowering of a temperature in the room 3 best. Since the temperature in the room 3 is lowered, the device 6 can keep a sufficient margin though an energizing time to the heater 2 is similarly prolonged at the time of steam-ironing. In dry-ironing, the temperature of the device 6 is not raised much to keep the sufficient margin since it is in the recessed place of the member 4 and the radiation heat of the heater 2 is never directly applied to it.
