Title: Ferrite magnetic material
Inventor: INUZUKA ATSUSHI
IPC: H01F1/37
Filed: 1989-08-16
Abstract: PURPOSE:To increase the density of a molded object, and obtain magnetic material of high permeability, by constituting ferrite magnetic material which is used for a transformer, an inductor, a magnetic head, etc., by binding highly crystalline ferrite magnetic powder of sphere type by using thermosetting resin or thermoplastic resin. CONSTITUTION:Magnetic material is constituted by using thermosetting or thermoplastic resin 2 for binding highly crystalline ferrite magnetic power 1 of sphere type, air gaps 3, and bores 4 of the magnetic powder 1. The magnetic powder 1 used in this case is powder wherein crystallization is sufficiently progressed by baking at a high temperature. The powder baked at 900 deg.C or more is preferable in the ordinary case. When soft magnetic material is wanted, large grain size is adopted, since small coercive force of magnetic powder is desirable. On the other hand, the filling density of highly crystalline ferrite magnetic powder of sphere type is decreased, so that the diameter up to 100-200mum is desirable in practice. For ferrite material, e.g. Ni-Zn system is used.

Title: Chip size detection, chip pitch detection, automatic chip arrangement data formation, and method and device for inspecting semiconductor substrate using them
Inventor: NAGAISHI HIROSHI
IPC: G06T1/00
Filed: 1989-08-16
Abstract: PURPOSE:To enable chip size and chip pitch detection and automatic chip arrangement data formation and inspection by sampling image data from arbitrary region of a semiconductor substrate and detecting the difference of characteristic amount of the image data between the inner region and the adjacent boundary region of the chip. CONSTITUTION:A histogram of brightness density is sampled from an image data sampling area 2 having a definite area on a wafer 1. Then, the fineness in the sampled region is discriminated based upon the characteristics of the histogram. Next, the sampling is repeated in the adjacent regions in the direction A oblique to the arrangement direction of chips 1a and in the direction B to detect the fineness in each region. Thus, the chip size and the chip pitch can be detected. Further, by moving by predetermined pitches, sampling the image data from the same position of the predetermined adjacent chip region and discriminating the presence of the chip based on the proximity to the reference data, registration and inspection of the chip arrangement data can be carried out automatically.

Abstract: PURPOSE: To estimate the speed of a vehicle regardless of the speeds of the wheels by measuring the sinkage of the front end section of the vehicle when the brakes of the vehicle are applied and integrating the measured values. CONSTITUTION: When the brakes of a vehicle are applied, the front section of the vehicle sinks. A potentiometer 39 converts the vertical displacement of the front end section into the change of the input voltage of an amplifier 49. The voltage from the variable contact of the potentiometer 39 in a state where the sink of the front end section is zero, namely, in a steady state is balanced by appropriately setting a potentiometer 51. The output of the amplifier 49 is supplied to a resistance filter and an A/D converter 57 constituted of a resistor 53 and capacitor 55. The output is converted into acceleration by means of a multiplier 22. The acceleration is integrated by means of an integrator 25 and filtrated by means of a filter 27.  Thereafter, the filtered integrated acceleration is used for estimating the momentary speed of the vehicle which is an input to an anti-lock brake system.

SOLUTION: Moving picture data with frame numbers N and N+1 are extracted on the basis of a value of a frame counter N (step S3), prescribed 9 points of the two moving picture data are extracted, a rank of the extracted moving picture is calculated (step S4), the rank is compared with a threshold value (step S5), and in the case of the threshold value <= the rank, a frame number N+1 is registered in a table TBL (step S6). On the other hand, in the case of the threshold value > the rank, no frame number is registered. Then the counter N is incremented by '1' (step S7), and whether or not a final frame is reached on the basis of the count of the counter N. When the frame is not the final frame, processing is restored to the step S3, where the extract processing of the image is repeated. When the frame reaches the final frame, this index generating processing is finished.

Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To ensure a high cost performance by arranging a base plate and an upper face plate on the opposing side face of a bent fin so that the air flows through the bent fin between the base plate and the upper face plate. SOLUTION: The heat sink 10 comprises a bent fin 12 mounted on a base plate 16 while being stabilized by an upper face plate 18. The heat sink 10 may be made of a copper sheet which is bent at the upper face 14 and the bottom face to form an accordion type fin 12.

Furthermore, a larger volume of air can be led through the cooling fin 12 while sustaining a wide channel between the fins so that the current velocity of the air flowing through the fins 12 is maximized. This structure realizes a highly efficient air-cooled heat sink having high cost performance.
