Title: Binary coding device for image
Inventor: FUJII KENJIRO
IPC: H04N1/403
Filed: 1985-07-17
Abstract: PURPOSE:To shorten a threshold setting time independently of the contrast ratio of an object by previously finding out the relation between the quantity of incident light upon a sensor and the lightness value of multilevel image data. CONSTITUTION:If an average lightness value P0 is changed to P1 when a reference illumination measuring area 3 is monitored and an average value of optional four points is found out, the optimum reference threshold value T1 of a threshold T1 changed from T0 is calculated from the shown curve on the basis of the average lightness value P1. When the optimum reference threshold T1 is expressed as a function f(alpha), the threshold T1 can be expressed as a secondary function including no common logarithm. In this case, K and alpha form the formula II. Provided that K is a constant determined by initial conditions P0, T0 and alphais a variable based upon the inverse P of the average lightness value of the reference illumination measuring area. At the binary coding of multilevel image data, the threshold can be set up within a short period corresponding to the illuminating condition.

Title: Thin film magnetic head
Inventor: YAMAZAKI HIDEKI
IPC: G11B5/31
Filed: 1988-06-24
Abstract: PURPOSE:To evade the deterioration of the reproduction output without deteriorating the magnetic permeability of a magnetic film by controlling the growing direction of the crystal grains at the sloping part of an upper magnetic film. CONSTITUTION:A lower magnetic film 3 is patterned in a magnetic core form by an ion milling process and then a magnetic gap layer 4 is formed by a sputtering process. In the same way, a conductor coil 6 is formed into an inter- layer insulated film 5 of an organic system. Then the 1st and 2nd upper magnetic films 71 and 72 are formed by a sputtering process and an Al2O3 layer is added between both films 71 and 72 as a protecting layer 8. Thus a thin film magnetic head 10 is obtained. Then the crystal grain growing directions of the slopping parts 7A of both films 71 and 72 are set approximately in the normal line direction. As a result, the aspect ratio of a pillar crystal is reduced and the magnetizing direction is not easily set toward the film thickness. Therefore the dispersion due to the vertical magnetic anisotropy is reduced for reduction of the coercive force. In such a way, the deterioration of the magnetic permeability can be evaded.

Title: Inter-frame compression coding device for picture signal
Inventor: NAMETAKE TAKESHI
IPC: H04N7/32
Filed: 1987-06-24
Abstract: PURPOSE: To improve picture quality by vector-quantizing an orthogonally transformed coefficient to a representative vector number in accordance with the character.  
     CONSTITUTION: A vector quantizing device 108 vector-quantizes the coefficient from an orthogonal transform circuit 406 to the representative vector number, and outputs it to a line and a vector quantizing decoding circuit 110. The representative vector is decided in accordance with the statistical property of the orthogonally transformed coefficient. The vector quantizing decoding device 110 reproduces the coefficient into the orthogonally transformed coefficient by the representative vector number from the vector quantizing device 108. An orthogonal inverse transform circuit 412 reproduces the decoded coefficient into a predictive error. An adder 414 adds the predictive error reproduced by the orthogonal inverse transform circuit 412 and that from a predicting circuit 419, reproduces a picture element value and writes it into a frame memory 417. Thus, the deterioration of picture quality is prevented to a part where the predictive error signal has much low frequency component such as the flat part of a picture, and a part where the predictive error signal has much high frequency component such as the edge part of the picture.

Title: Print controller, printer, method therefor and printing system
Inventor: FURUYA YOJI
IPC: H04N1/32
Filed: 1996-06-18
Abstract: PROBLEM TO BE SOLVED: To provide a low-cost host base printer in which an overrun scarcely occurs. SOLUTION: A host system 1 delimits compressed image data into blocks of predetermined size, and sends them to a printer. The printer stores the respective blocks in reception buffers 9. If one page cannot be sufficiently stored in the buffer, first block is started to be output, and the residual block is stored in the area occupied of the vacant first block. Thereafter, the blocks for constituting the page are sequentially stored in the buffers 9 in parallel with succeeding printing of the blocks. Since the second block and following blocks are sufficiently smaller than the first block, the expanding process of the image by an image expanding/video transfer circuit 6 is scarcely delayed from a print output, and hence overrun scarcely occurs.

Title: Suspension control device
Inventor: WADA SHUNICHI
IPC: B60G17/00
Filed: 1988-06-24
Abstract: PURPOSE:To control the characteristics of a suspension optimally by carrying out drift correcting calculations of the height of the suspension, the elasticity of a spring, the torsional action of a stabilizer, and the neutral acceleration, based on the output signal of an acceleration sensor. CONSTITUTION:An acceleration sensor 8 can synthesize and simultaneously output the vertical acceleration and the lateral acceleration of a vehicle body. Thus, the characteristics of a suspension is controlled by judging the state of the vertical and lateral accelerations by the output of said acceleration sensor. When a drift resulting from moisture and using period is caused in the output of the acceleration sensor 8, an offset is formed in the value of the neutral acceleration. A suitable correction of this offset enables the roll suppression control at the time of turning in an optimal condition. According to this invention, the use of th4 acceleration sensor 8 enables a simplified correction processing, and the number of acceleration sensors can be reduced.

Abstract: PROBLEM TO BE SOLVED: To improve heat exchanging efficiency of an air-cooled oil cooler by disposing the air-cooled oil cooler at a downwind position of air blowing of a condensing part formed at the end part on the downstream side of a refrigerant flow passage. SOLUTION: In the engine compartment of an automobile, a condenser 1, a radiator 5, and an air-cooled oil cooler 4 are disposed in order from its front end. By introducing the air flow (blowing air) 2 generated by the rotation of a fan 12 between the respective fins of the condenser 1, refrigerant gas is flowed gradually from the upper part of a tube 1a to its lower part for cooling, and is condensed at its lower end to be changed into liquid at medium temperature. The blowing air 2 which has passed through the condensing part 3 at the lower part of the condenser 1 is kept at a lower temperature than the one that has passed through other parts. Therefore, by disposing the air-cooled oil cooler 4 on the back side of the condensing part 3 of the condenser 1 and the low water temperature part 6 of the radiator 5, it is possible to improve its cooling efficiency.
