Title: Vtr device
Inventor: YAMADA ICHIRO
IPC: H04N5/782
Filed: 1993-02-24
Abstract: PURPOSE:To automatically generate and output a basic video image by outputting a video image to a receiver via an RT converter, tuning the video image to a receiver so as to reproduce the video image thereby having only to turn on a power supply at the start of use. CONSTITUTION:An on-screen IC used for video recording reservation or time setting or the like is used for an on-screen IC2 being a component of a VTR 1. The operation modes are two modes such as external synchronization mode and internal synchronization mode and in the case of external synchronization mode, a microcomputer 8 allows a video signal inputted to the screen IC2 to be outputted as it is to a video circuit 4 based on a display-off instruction from a computer 3. In the case of display-ON instruction, the microcomputer superimposes a character onto the video signal inputted to the screen IC to provide an output. In the case of the internal mode, the video signal inputted to the screen IC2 is interrupted based on display-OFF and only a blue-back picture is outputted to the circuit 4 and in the case of display-ON instruction, the video signal is interrupted and a character is superimposed on the video signal of the blue back picture to provide an output.

Title: Dust collecting electrode
Inventor: TAKASHIMA KAZUNARI
IPC: B03C3/45
Filed: 1988-02-18
Abstract: PURPOSE:To reduce the lowering of dust collectivity with the lapse of time and stabilize the dust collectivity, by defining a large space between either of a first or second conductive layer and the facing insulating layer than those defined between the other layers. CONSTITUTION:A first conductive layer 1, a first insulating layer 3, a second conductive layer 2 and a second insulating layer 4 are stacked and wound in such manner as to make a space t3 between the second conductive layer 2 and the second insulating layer 4 layer than the other spaces t1 and t2. The dusts electrically charged by the dust collecting electrode thus formed are adhered to only the surface of the second conductive layer 2 with the largest space of the spaces t1-t3, while the dusts will not adhere inevitably to the surface of the insulating layer with a smaller space. Since the positively charged dusts adhered to this second conductive layer 2 are neutralized electrically, the electric field of the space t3 between the second conductive layer 2 and the second insulating layer 4 is not relaxed, thereby preventing an abrupt drop in the dust collectivity with the lapse of time.

Title: Method and device for analyzing sentence
Inventor: FUKUSHIGE TAKAO
IPC: G06F17/27
Filed: 1989-02-16
Abstract: PURPOSE:To analyze sentences at a high speed and with high efficiency by securing the correspondence of units, i.e., the elements to various grammar elements and analyzing the sentences through the interaction of these elements. CONSTITUTION:A proper element type is decided to each word separated from an input sentence by reference of a vocabulary dictionary part 12 and based on the information on this reference. At the same time, a corresponding element is produced by reference to an element template part 13. An analyzing process is carried on via the reception of a message produced by the elements, the evaluation of the condition part having an element rule, and the production of an autonomous pattern through the repetition of a proper act based on the result of the evaluation. Then the analyzing process is through when no rule to be applied is available any more to all elements. Thus a sentence can be locally analyzed and therefore the parallel analyzing processes are easily attained. Then the analyzing speed is increased by giving previously the behavior rule of the element belonging to each type to each element.

Abstract: PROBLEM TO BE SOLVED: To make a number so as to be checkable even in a modicum of light by using fluorescent material and a luminous substance in a full or partial section of letters and the like and other than these letters and the like. SOLUTION: A part 1 of letters and the like is used with fluorescent material and a luminous substance irrespective of unevenness.

Otherwise, the fluorescent material and the luminous substance are used in both of the part 1 of the letter or the like and the part 2 other than the letter or the like. Since a number plate is brightly seeable even in the case of being utterly no light, or even in a modicum of light owing to the effect of those of fluorescent material and luminous substance, the recognition of numbers becomes facilitated.

Abstract: PURPOSE:To keep a stance and energizing force of a strap plate constant, and reduce a manufacturing cost without influcencing on an abrasion adjusting mechanism by fixing the strap plate of a clutch cover assembly to a support member which is not displaced in an axial direction. CONSTITUTION:When abrasion occurs at a facing 23 at the usage of a clutch, fulcrum ring 24 and a pressure plate 21 are moved to the side of a flywheel 15 by the pressurizing force of a diaphragm spring 22. A wedge collar 31 of a moving mechanism 40 is abutted against the flywheel 15 so that the wedge collar 31, a wedge 32 and a bolt 33 are not moved in respect to the flywheel 15.

As a result, a gap is generated between a flange 24b of the fulcrum ring 24 and a head 33a of the bolt 33, correspondingly to abrasion. The position of the fulcrum ring 24 is not varied in respect to a clutch cover 20.
