Title: Circuit for controlling driving of electric valve
Inventor: OKATSUCHI CHIHIRO
IPC: H02M1/08
Filed: 1979-03-15
Abstract: PURPOSE: To eliminate the effects of power-supply-voltage variation by transmitting pulses having different phases to the sencondary side of a transformer and giving an ON signal thereto; and obtaining an OFF signal by applying a reverse voltage to the transformer.  
     CONSTITUTION: When a driving signal is given to a one-shot circuit 26, transistors 6 and 7 are turned on, the outputs are generated on the secondary sides of transformers 4 and 5, and a base current IB is flown to a main transistor 18. Then, the output of an oscillator 12 alternatingly turns the transistors 6 and 7 on through an AND circuit and an OR circuit, thereby IB is maintained. When the driving signal becomes off, the reverse output voltage of the transformers 4 and 5 are applied to a diode 32, thereby a thyristor 35 is turned on, and IB is flown to the negative direction. Therefore, the base current of the main transistor 18 becomes twice at the time of rise-up, and the ON period is shortened. At the time of OFF, the direction of the current is automatically reversed, and the switching loss can be made small.

Abstract: The object of the invention is a rear-vision mirror for autovehicles, in which the mirror holder is angularly movable relatively to a housing (3) around a horizontal pivot axis (X-X) and around a vertical pivot axis (Y-Y) by means of two driving units (AX,AY) which are accomodated in the housing (3) for the mirror holder and are each associated with one of the said pivot axes. The said driving units (AX,AY) comprise each an electric motor (14) which by means of a mechanical transmission (16,15,17,18,21,20) drives a rack (13) arranged substantially at right angles with the mirror holder (1), which is articulatingly connected thereto (at 113) and is guided in the housing (3) for the mirror holder. A control device is provided which allows to move the mirror holder into the required position by having it angularly moved by means of the two electric motors (14) around the one and/or the other pivot axis (X-X, Y-Y), and which also allows to store one or more positions of the mirror holder and to have the same automatically moved into one or the other of these stored positions by means of a selecting respective control and with the aid of detectors (24) of the angular position of the mirror holder around each one of the two pivot axes (X-X, Y-Y). According to the invention, the detector of the angular position of the mirror holder in relation to each pivot axis (X-X, Y-Y) is in form of a potentiometer (24) the actuation of which is derived from a member (20) of the drive between the electric motor (14) and the rack (13) associated with the respective pivot axis, the rack (13) being not disengageably connected to the member (20) for actuating the potentiometer (24), while in the drive between the said member (20) for actuating the potentiometer (24) and the respective electric motor (14) a friction coupling (21) is interposed.

Title: Quantizing method
Inventor: TE DOU UI
IPC: H04B1/66
Filed: 1993-02-19
Abstract: PURPOSE:To reduce the loss of a quantizer without affecting a bit stream syntax by quantizing entire spectrum samples in an interval by a correcter and quantizer using the entire dynamic range of an intermediate tread quantizer. CONSTITUTION:The quantizer dynamic range when bit distribution data WL = 3 is extended to + or -1-+ or -1.17 or 7/ 6. This syntax is not accepted in the bit stream, and a conversion factor must be reduced to k=1.17 (or 7/6) so that the first bit stream syntax can be maintained. Then, the minimum error epsilon can be applied by an expression I by this reduction. A quantization noise can be logically improved, and the error can be further reduced by quantizing the conversion factor even when the effect is a little reduced. This intensifying method is especially valid for a high frequency to which the rough quantization, that is, the quantization of data less than 3 bit and saving are extremely important.

Title: Method and apparatus for defoaming liquid resin
Inventor: SATO HIDEO
IPC: H01L21/56
Filed: 1992-01-23
Abstract: PURPOSE:To enhance the defoaming treatment efficiency of a liquid resin without scaling up an apparatus. CONSTITUTION:An empty bottomed cylindrical container 3 is provided on the turntable 31 provided in a vacuum tank 1 reduced in pressure and one end part of the liquid resin supply pipe 33 connected to a liquid resin tank 36 is almost brought into contact with the upper part of the inner wall of the container 3. When the liquid resin 2 in the liquid resin tank 36 is supplied to the upper part of the inner wall of the container 3 through the liquid resin supply pipe 33, said resin 2 is supplied to the entire periphery of the upper part of the inner wall of the container 3 because the container 3 is rotated along with the turntable 31 to naturally fall along the inner wall of the container 3 and diffused over the entire inner wall of the container 3 to be received in the container. When air bubbles are generated on the surface of the liquid resin 2 diffused over the entire inner wall of the container and the surface of the liquid resin 2 received in the container 3, the generated air bubbles burst open by the pressure difference between the container 3 and the vacuum tank 1 to defoam the liquid resin 2.

Abstract: PURPOSE:To rapidly adjust a large expansion and contraction by constituting titled adjuster through the relative turn between two members screw-joined so that two members are relatively shifted in the axial direction by releasing the screw-connection between two members. CONSTITUTION:The screw part 3 of a small-diameter body 2 is engaged with the fixed half-divided body 4 and the movable half-divided nut bodfy 6 of a large -diameter body 1, and expansion adjustment is performed by the relative turn between the small-diameter body 2 and the large-diameter body 1.

Abstract: PURPOSE:To decide images with high accuracy by performing orthogonal transformation for each block to obtain the average density value difference between adjacent blocks as well as the edge direction in a block and deciding a halftone spot area and a character area. CONSTITUTION:The original picture data 201 is inputted to a Hadamard transforming part 202 for each (4X4)-picture element block and undergoes the orthogonal transformation for each block. A coefficient Y11 obtained after said transformation is given to an average value difference detecting part 206 via a 1-block delay part 203. Thus the average density value difference is obtained between blocks. A segmentation part 208 sorts image data into four categories according to the edge direction of the input block. Then a deciding part 212 decides whether the image data means a halftone spot area or a character area based on the average density value difference and the edge direction in the block.
