Title: Adjusting apparatus
Inventor: BOBII DABURIYUU HOOKU
IPC: B01F7/04
Filed: 1987-10-14
Abstract: A conditioning device for an extruder (14) includes two juxtaposed, frustocylindrical, intercommunicated chambers (24-26), one chamber of which has a greater cross sectional area than the other chamber. A mixing shaft (28) centrally located within the small chamber carries a number of radially extending beaters which rotate at a speed twice that of the rotational speed of paddles mounted on a second mixing shaft (36) located in the large chamber and material introduced into the vessel is passed from side-to-side between the two chambers while being advanced along the length of the vessel. The use of relatively fast moving beaters within a small mixing chamber in combination with relatively slow moving paddles in a larger mixing chamber enables flour-like materials to be properly blended with water with both sufficient agitation and proper retention times within the vessel. In an alternate embodiment of the invention, the vessel is tiltable about an axis parallel to the longitudinal axis thereof, in order to bias the materials under the influence of gravity toward one chamber or the other and to thereby vary the residence time of the materials within the vessel and the mixing characteristics of the device.

Title: Method and apparatus for image coding
Inventor: ZEN SHIYOUKIYUU
IPC: H04N19/136
Filed: 1994-10-25
Abstract: PURPOSE: To facilitate bit allocation fitted to a specified area by detecting a picture in an auxiliary block unit constituted of the prescribed number of unit blocks and deciding the compression integer for cording video data at the fixed bit rate adapted to complexity. CONSTITUTION: A complexity degree is calculated by using the pixel value of an input value in a complexity degree calculation part 52. A complexity degree normalization part 53 normalizes the complexity degree for respective specified areas. A zero coefficient counting part 54 counts a zero coefficient smaller than ±1 among discrete cosine conversion coefficients converted at a discrete cosine conversion rate 51. A zero coefficient normalization part 55 normalizes the zero coefficient for the respective areas. A weighting value calculation part 56 calculates the zero coefficient counted by the counting part 54 and a shift weighting value at the compression rate for the respective specified areas. An adder 57 adds the values, generates a compression integer and outputs it to a quantizer 58. Thus, a quantization interval with respect to the discrete cosine conversion coefficient is decided by the compression integer and a quantization matrix.

Title: Optical card
Inventor: OGAWA YOSHIHIRO
IPC: G11B7/24012
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To reduce generation of warpage even in the case of an optical card with embossment made of polycarbonate by forming projecting parts in an embossed part on both surfaces of a transparent substrate and a protective substrate. SOLUTION: A contour part of a letter '0' (zero) in the embossed part 14 is an embossed projecting part 13 for information display displaying characters and a central part of the letter '0' is unnecessary for reading embossment. Accordingly this part is extruded as a projecting part to a reverse surface to make an embossed projecting part 11 for adjusting warpage. Consequently, generation of warpage can be suppressed to a minimum even when the optical card is subjected to embossing finish by designing the height of the embossed projecting part 11 for adjusting warpage so that the embossed projecting part 13 for information display and the embossed projecting part 11 for adjusting warpage have the same elongation.

Title: Differential current amplifier circuit
Inventor: TANAKA TATSUO
IPC: H03F3/45
Filed: 1989-10-06
Abstract: PURPOSE:To increase a current gain and to reduce current consumption with simple circuit constitution by supplying a clean DC current with no signal current superimposed thereon. CONSTITUTION:When a signal current (I+i) being the superimposition of a signal component (+i) on a DC component I is inputted to a signal input terminal IN1 and a signal current (I-i) being the superimposition of a differential signal component (-i) on a DC component I is inputted to a signal input terminal IN2, a base common connection point of transistors(TRs) Q1, Q2 reaches an imaginary ground level, a signal current component i1(=i) flows to resistors R1, R2 and does not flow to the Trs Q1, Q2. Thus, a clean DC current with no signal current superimposed thereon flows to the Tr Q3 and a DC current of 2n.I flows to a Tr Q4 in current mirror connection to the Tr Q3 in a ratio of 1:n.

Title: Automatic mask device
Inventor: HACHIMAN MAKOTO
IPC: G03F7/20
Filed: 1988-10-14
Abstract: PURPOSE:To form mask aperture regulating plates in the form of thin films and to prevent the out-of-focus regions in the peripheral part of an exposing area from expanding largely by separately disposing the mask aperture regulating plates and light shielding film leading plates by a pair of leading means so that the tension of light shielding films do not act on the mask aperture regulating plates. CONSTITUTION:This device consists of the mask aperture regulating plates 14a, 14b disposed with a pair of the leading means 3a, 3b in proximity to a light transparent plate 5 and the light shielding film leading plates 15a, 15b fixed with the light shielding films 12a, 12b. Since the light shielding film leading plates 15a, 15b and the mask aperture regulating plates 14a, 14b are separately disposed on top and bottom, the take-up force of light shielding film take-up rollers 11a, 11b act only on the light shielding film leading plates 15a, 15b and do not act on the mask aperture regulating plates 14a, 14b. The formation of the mask aperture regulating plates 14a, 14b of thin sheet materials is, therefore, possible. On the other hand, the mask aperture regulating plates 14a, 14b formed in the form of thin films are disposed in proximity to the light transparent plate 5 and the mask aperture regulating plates 14a, 14b of the other one pair of the leading means are disposed thereon in proximity thereto so as to intersect with each other. The out-of-focus regions in the peripheral part of the exposing area by the mask aperture regulating plates are substantially prevented from expanding in this way.

Abstract: PURPOSE:To correctly hold an electronic part in a prescribed state even if the outer shape and insertion state are different, by installing a holding means for holding the electronic part in a prescribed state according to the outer shape and the insertion state of the electronic part. CONSTITUTION:When an electronic part 17 is nipped by the inserting fingers 16 and 22, a steel ball 24 moves in sliding in an electromagnetic holder 14 according to the tilt of the outer shape of the electronic part 17, outer strain or outer shape, and the electromagnetic holder 14 is floated up by blowing out the compressed air from the air blow-out ports 12 and 27 and other plural air blow-out ports. The tilt of the inserting fingers 16 and 22 and the position of the electromagnetic holder 14 are determined according to a slide block 9 and the outer shape of the electromagnetic part 17 in light sliding state, and then the electromagnetic holder 14 is excited, and fixation is performed when an inserting head center and the center of the inserting center are allowed to coincide. The inserting fingers 16 and 22 rise in the state nipping the electronic part 17, and shift insertion to an insertion position is carried out.

Title: Vehicle control device
Inventor: FUKUMOTO TETSUYA
IPC: B60T8/1761
Filed: 1992-09-03
Abstract: PURPOSE:To heighten vehicle control performance by estimating a road surface condition accurately by fuzzy inference. CONSTITUTION:Output of a vehicle body vertical direction G sensor 1 and wheel speed sensors 2-5 is inputted to a microcomputer 10, and a vibration degree of a specific frequency component and a low (mu) road degree are calculated, and according to these parameters, an estimate value of a road surface condition such as a 'good road' or a 'bad road' is obtained by fuzzy inference, and control is identified. According to output of a vehicle speed sensor 51, operation is carried out on a control value to carry out control, for example, roller control, dive control and so on except a suspension. According to these control values, the optimal damping force is selected, and a damping force control value is outputted to variable suspensions 2-24. Thereby, unlike operation to estimate only a road surface (mu), since the 'bad road' such as a gravel road or an earth and sand road or the 'good road' unlike that are judged accurately and this estimate value is applied to vehicle travel control, control performance is heightened further, so that comfortableness to ride and maneuvering stability can be reconciled with each other.

Inventor: SHIRAISHI TOMOHIRO
IPC: H01L23/12
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To ensure proper through-hole conductors and further reduce the pitch of the conductors. SOLUTION: A BGA 2 of a BGA.IC 1 is provided with a base 3 as a core 4. A ground conductor 5 is formed on the first major surface of the core 4, and an insulating film 9 is formed on the entire ground conductor 5, a plurality of signal lines 10 being formed on the insulating film 9 into a radial pattern. A bonding pad 11 is formed on the inside ends of the signal lines 10, and a pad 12 for bump is connected electrically with the outside ends of the signal lines 10 through the through-hole conductors 15 formed into narrow through- holes 14. Since the pitch of the signal lines can be reduced by forming the through-holes into narrow shape, the wiring density of the signal lines can be improved. In addition, the diameter of the through-holes is small but their length is large and sufficient areas can be ensured on the inner surface of the through-holes.  Therefore, the through-hole conductors can be formed properly, and degradation in the electrical characteristics of the through-hole conductors can be prevented.

IPC: H01L23/12
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To adjust the thickness of a sealing film, between columnar electrodes of a semiconductor device, in its early stages. SOLUTION: The sealing film 16 is formed with a print mask and a squeegee 15. In this case, the tip of the squeegee 15 has a flank almost in a V-shape and is pressed in between columnar electrodes 12 for printing. Then the sealing film 16 is recessed between the columnar electrodes 12. In this case, the thickness of the sealing film 16 is directly proportional to the weight of liquid sealing resin printed on a silicon substrate 11. The print quantity (weight) of the liquid sealing resin printed on the silicon substrate 11, is in inversely proportional to the intrusion quantity of the squeegee 15 (how much the tip part of the squeegee 15 is pressed inbetwen the columnar electrodes 12 from the top surface of the columnar electrodes 12).  For the purpose, the press-in quantity of the squeegee 15 is adjusted to suppress the weight of the liquid sealing resin printed on the silicon substrate 11, and consequently the thickness of the sealing film 16 can be controlled.
