IPC: B28B15/00
Filed: 1989-12-21
Abstract: PURPOSE:To form a chamfered face on a cut surface by a method wherein an extruded and formed belt is formed by an extruder; a groove is embossed on a portion where the belt is cut, during conveyance by a conveyor; the belt is subsequently dried; the groove part is then detected so that the belt is cut by a running cutter in a predetermined length; and further the cut belt is burnt. CONSTITUTION:An extruded and formed belt A is extruded and formed by an extruder 3 and is conveyed by a driving conveyor 10. A groove 'b' is embossed on a portion, at which the belt A is to be cut and whose cut surface is to be formed into a decorative face, by an embossing machine 6 disposed in the vicinity of the mouthpiece 4 of the extruder 3. The belt A then enters a drying chamber 11 to be dried. Then, a detector 12 detects the groove 'b', and a running cutter 13 is operated to cut the extruded and formed belt A in a predetermined length. The resultant dried plate B cut in a predetermined length is sent into a burning furnace 15 to be burnt. After burning, the plate B is sent to a subsequent step by a conveyor 22. Thus, a chamfered face is formed on the cut surface, and design and three-dimensional feeling can be enhanced when the execution of work is done.

Title: Control device for lock-up clutch in automatic transmission
Inventor: OBA HIDEHIRO
IPC: F16H59/14
Filed: 1990-11-29
Abstract: PURPOSE:To reconcile improvement in responsiveness and improvement in stability of a system in high order by combining feed forward control with feed back control according to engine torque and its learning control in the case of controlling slip volume. CONSTITUTION:A lock up clutch 24 is controlled at high speed up to almost close level to desired slip volume by means of duty ratio corresponding to engine torque and learning correction volume, as it were, by means of feed forward control, and further, according to the difference between actual slip volume and the desired slip volume, feed back control is carried out so that the actual slip volume can reach the desired slip volume. As a result of this, correction volume by means of the feed back control becomes a very small value, so that even if feed back gain is not made large so much, that is, if the system is put under a quite stabilized condition, an excellent follow-up ability can be obtained. Furthermore, for example, the control method needs not to be switched according to an acceleration/deceleration time or a constant speed time, so that the slip volume is never changed in a step form in the case of changing speed.

Title: Tool holder
Inventor: KOMINE TAKESHI
IPC: B23Q3/12
Filed: 1993-12-27
Abstract: PURPOSE:To uniformly stick the overall surface of a tapered shank part on a taper axis of a spindle and to secure high machining precision at the time of high speed machining by making threads of the tapered shank part and a screwing part of a pull bolt of saw tooth screws or square screws. CONSTITUTION:A thread part 6e of a pull bolt 6 is made into a saw tooth thread 7, and a receiving surface 7a to receive tightening force at the time of screwing is formed rectangular to the axial direction. Consequently, as the tightening force of the pull bolt 6 works in the axial direction and component force in the diametrical direction is not generated, only the tightening force in the axial direction works on a received surface of a thread part of the head end part of tapered shank part 3 but the component force is not applied in the diametrical direction, and accordingly, the head end part is never expanded. Consequently, the overall surface of the tapered shank part 3 is uniformly stuch against a taper axial hole 12 of a spindle 11 even when the pull bolt 6 is changed.

Title: Small sized electronic device system
Inventor: WATANABE AKIRA
IPC: G06F15/02
Filed: 1991-12-17
Abstract: PURPOSE:To attain the excellent carrying performance and to facilitate the entry job by forming the system with a paging receiver as a 1st electronic device, a connection mechanism connecting the receiver and an electronic notebook as a 2nd electronic device. CONSTITUTION:When a CPU 14 for a paging receiver 10 discriminates the presence of a selective call to itself, received item data are once stored in a RAM 17. A CPU 24 of an electronic notebook 20 discriminates whether or not a reception signal receives via a connector 23 from the receiver 10. Upon the discrimination of the presence of the reception signal, the CPU 24 transfers the item data stored in the RAM 17, expands message data by referencing a conversion table of a RAM 26 and displays and outputs the data onto a display section 22. Thus, the user simply revises the message data, and since the electronic notebook and the paging receiver both have the excellent carrying performance, a message is communicated between users independently of any location.

Title: Document input device
Inventor: SATO JUN
IPC: G06K9/03
Filed: 1990-11-29
Abstract: PURPOSE:To improve the recognizing accuracy of the post-processing by carrying out the post-processing before putting a character code of a null character and a null line into a character code string. CONSTITUTION:A shaping part 27 calculates the average character and line pitches of a character string based on the coordinates of each character read out of a character information buffer 23 and then divides the coordinates of each character by the average character and line pitches for calculation of the row and the column of each character included in the character code string. In this case, the character code of a null character and a null line are put into the character code string outputted from a post-processing part 25 so as to secure the approximation to a character position on an original. Then a coded document is outputted through a terminal 28. In such a way, the post- processing is carried out before the character code of the null character and the null line are put into a character code string. So that the word of the character code string is never divided by the character code of the null character and the null line. Thus the recognizing accuracy is improved for the post- processing.
