Filed: 1986-10-28
Abstract: PURPOSE:To prevent the generation of an end part flaw on a unloaded and piled board like object by decelerating the speed of sending said board like object into a piler by means of a send-in means to piler, from a speed synchronized with the conveying speed of a conveying conveyor to a speed at which a flaw is not generated at the time of unloading and piling said board like object. CONSTITUTION:At the point of time when the conveyance of regular-size board like objects 3 from a shear 1 to a line is started, the high speed rotation of a pinch roller 6 synchronized with the conveying speed is started. And, the board like object 3 is received by the pinch roller 6 and sent into a piler 5 and, after its rear end passed through a sensor 8, a defined time is measured by a counter, to decelerate the rotation of the pinch roller 6. After the board like object 3 is unloaded and piled on a piler 5, the pinch roller 6 is returned to the high speed rotation in line with the arrival of the following board like object 3 by means of a pulse signal. Due to this rotation control of the pinch roller 6, a shock caused by the transferring inertia of the board like object 3 to a stopper 9 can be reduced and controlled to the extent that an end part flaw is not generated.

Title: Picture relay transmission method for facsimile communication system
Inventor: SHIBATA HIROSHI
IPC: H04N1/00
Filed: 1991-09-11
Abstract: PURPOSE:To improve the picture quality of a reception station by allowing each relay station to transmit a line density standard picture to have been transmitted in the unit of millimeter as it is. CONSTITUTION:A request station A transmits a read original picture as it is regardless of the capability of a relay station B, and the station B transmits the picture as it is regardless of the equipment capability of a station C. The station C discriminates the equipment capability of a reception station D and transmits the received picture because the station D can receive the picture. The station D records and outputs the received picture in an original size B4 in a high line density. When the recording capability of the station D is low in comparison with the capacity of the received picture, the station C transmits ancillary data and applies reduction or line density conversion to the picture in response to the reception capability of the station D and transmits the result. In the case of the G4 mode set to the station D, the picture is called to the station D in the setting of the G4 mode, the line density standard picture in the millimeter system received in the G3 mode is converted into the G4 mode inch system. Thus, the station D implements recording output of the picture in the A4 size and in high line density, then the recording picture quality is improved.

Title: Local area network device
Inventor: KATO HARUO
IPC: H04L12/28
Filed: 1984-12-07
Abstract: PURPOSE:To suppress an overhead as much as possible and speed up data transmission by providing the 1st network which sends transmit data and the 2nd network which wends control signals for data transmission carried out through the 1st network. CONSTITUTION:For example, when picture data of one megabytes is transmitted from a node N2 to a node N6, the node N2 after receiving a message signal showing that preparations for data reception is completed from the node N6 through the 2nd network 2 transmits the picture data of one megabytes to the node N6 through the 1st network 1. The completion of the picture data transmission is judged by the both nodes N2 and N6, but the node N6 discriminates whether the picture data is received accurately or not and when it is judged that the picture data is received, that is reported to the node N2 through the 2nd network 2. Consequently, the node N2 confirms that the picture data of one megabytes is transmitted completely.

Title: Mos transistor
Inventor: KUMAMOTO TOSHIO
IPC: H01L27/12
Filed: 1987-10-14
Abstract: PURPOSE:To achieve high speed operation without losing transistor characteristics by providing a potential for a semiconductor substrate and not allowing the capacitance of a depletion layer between a drain and a semiconductor substrate to increase. CONSTITUTION:A source region 2 is not so deep that it does not reach an insulating substrate 4. Ions whose type is similar to a semiconductor substrate are injected into a region adjacent to such source region 2 and opposite to a gate electrode 1 relative to a drain region 3. Accordingly, a potential for the semiconductor substrate can be obtained from such ion injected region, and the kink effect can be prevented. In depletion layers 6, 7 which will become load capacitance for the transistor, since the drain region 3 is so constructed that it reaches the insulating substrate 4, depletion layer capacitance in this region is small. This prevents the transistor from losing its characteristics, whereby the transistor capable of operating at high speeds can be constructed on the insulating substrate.
