Title: Isdn telephone system
Inventor: YAMAMURA SHUNEI
IPC: H04M1/253
Filed: 1991-08-30
Abstract: PURPOSE:To attain extension talking free of charge between telephone sets by not sending a message to an ISDN but returning it to a telephone set when a TEI value of a setup message received from the telephone set is not a non- automatic allocated value. CONSTITUTION:When a connector 2 receives a setup message from a telephone set 4a, the connector discriminates whether or not a TEI value received together with the message indicates a non-automatic allocated value. When the TEI value corresponds to the non-automatic allocated value, the setup message using the content of an incoming address/incoming subaddress information element as an extension number is set based on the received message and the message is sent to a telephone set. As a result an opposite telephone set is called and an extension talking not via the ISDN is implemented with the telephone set 4a through the reply of the above telephone set. Thus, the talking charge is made free.

Title: Video correction circuit
Inventor: HAMAGUCHI MITSUHIRO
IPC: H04N1/40
Filed: 1988-09-30
Abstract: PURPOSE:To switch the picture quality simply by correcting a digitized gradation data depending on a data selected by a switching signal among plural kinds of correction data stored in a memory. CONSTITUTION:A video correction circuit 8 has 3 ROMs 10 storing respectively a correction data correcting the gradation data of each color and the gradation data of each color outputted by each A/D converter 6 is inputted respectively to a low-order address line of each ROM 10. Moreover, two kinds of the correction data are stored to each area of a high-order address represented by 2 kinds of switching signals such as 0 and 1. The input video signal is subject to color conversion by a color decoder 2 and converted into an 8-bit gradation data corresponding to the brightness of each picture element by the A/D converter 6 and inputted sequentially to a low-order address line of the ROM 10. Then the correction data V' corresponding to the low-order address designated sequentially by the gradation data is read sequentially from the ROM 10. When the displayed video image changes to a whity image entirely due to a scene with mist and is not easily observed, the switching signal is changed over to use the correction data V'.

Title: Medium aligning device
Inventor: SHIMAOKA TAKASHI
IPC: B65H9/10
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To accurately align a medium along a medium reference face while correcting the inclination of the medium. SOLUTION: A pair of movable bodies 10, 11 are moved in mutually approaching directions to clamp a medium 2 on a medium conveying path 1 by medium clamping rollers 20, and the movable bodies 10, 11 are moved toward the outside of a medium reference face 5 to make the medium 2 abut on the medium reference face 5 to align the medium 2. In the case of the side edge of the medium 2 being inclined with respect to the medium reference face 5, the conveying direction front side or rear side of the medium 2 first abuts on the medium reference face 5.  The force of drawing the medium 2 toward the medium reference face 5 side by the further movement of the movable bodies 10, 11 thereby acts as the force of rotating the medium 2 within a plane parallel with the medium conveying path 1 with the abutting part of the medium 2 abutting the medium reference face 5 first, as a fulcrum, but the medium clamping rollers 20 are made rotatable around an axis orthogonal to the medium conveying path 1 to easily correct the inclination of the medium 2.
