Title: Hall device
Inventor: HOUJIYOU AKIMICHI
IPC: H01L43/06
Filed: 1980-09-30
Abstract: PURPOSE:To hold a Hall device with a high yield within a fixed range of an input resistance therein by a method wherein input/output resistance is different from an arm part to another of the body of a Hall device, and also it is so constructed that any influence is not exerted on a characteristic of the device even some input/output (I/O) terminals are exchanged. CONSTITUTION:The body of a device 20 with two crossarms has input terminals 11 and 12 and output terminals 13 and 14. Crossarms are W1 and W2 wide and l1 and l2 long, respectively. In terms of the length l1 and l2, the difference of the resistance between terminals 11 and 12 from the resistance between terminals 13 and 14 is within + or -10%, and l1/W1 and l2/W2 are selected to be 2 or larger. With this construction, the difference of sensitivity is not practically recognized even if I/O terminals are changed, and it was verfied without any exception in the test at 125 deg.C, too. This structure provides that a large degree of freedom is obtained in a Hall device production process where any approach so far is not available after production of a pellet, and thereby the reliability is not affected even when inputs and outputs are mis-connected.

Title: Device for measuring flow rate of combustible fluid
Inventor: KOHAMA TOKIO
IPC: G01F1/684
Filed: 1983-07-26
Abstract: PURPOSE:To enhance measuring accuracy, by wrapping a flow-rate measuring part of a combustible fluid having temperature dependent resistors with a heat insulating layer, thereby providing a heat insulating structure. CONSTITUTION:An electric heater 3 and temperature dependent resistors 41-43 are enclosed in the inside of a flow-rate measuring pipe 15. A flow-rate measuring part of LPG is formed by those parts. A heat insulating layer 8 is provided so as to wrap the heater 3 and the temperature dependent resistors 41-43, and a heat insulating structure is provided. Therefore, at this part, the heat of the high temperature LPG in comparison with free air is not taken away by the free air. Thus the temperature difference does not occur in the LPG gas when the heater 3 is not operated, and the temperature difference is yielded only when the heater 3 is operated. As a result, the measurement errors caused by the temperature gradient due to heat other than the heater 3 can be removed. In this way, the measuring accuracy can be enhanced.

IPC: H04N1/405
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of a dummy contour caused by a pseudo half tone expression based on multilevel pixels. SOLUTION: The 0th-order interpolation of one pixel 701 in an input multilevel image 400 is performed in main and sub scanning directions and an interpolated image 710 is generated by transforming one pixel (701, for example), to four pixels (711-714, for example). Next, a binary image 720 is generated by binarizing the interpolated image 710 through an average density preservation method (area gradation method). Next, the pixel value of one pixel (731, for example), is determined by adding the pixel values of four pixels (721-724, for example), in the binary image 720 for the unit of these four pixels and an output image 730 composed of quinary pixels is generated.

Abstract: PURPOSE: To ensure the quick and assured detection for the commutaion failure of all phenomena by detecting the time during which the current does not flow for each phase at the AC side and then detecting the commutation failure in case the detected time exceeds 60°+α°.  
     CONSTITUTION: The circuit consists of the following units: AC current detectors 16R, 16S and 16T to detect the current for each phase at the AC side; polarity converters 21R, 21S,and 21T to convert input AC(A) to DC signal (B); zero current detector 22R, 22S and 22T; and comparator 23R, 23S and 23T to generate the outpt when discontinuation period 60°+α° is set with the detection output of DC current detector 15 and when the output of detectors 22R∼22T is more than 60°+α°. In case the current of each phase at the AC side does not flow more than the time of 60°+α°, the commutation failure is detected. Thus, even the commutaion failure of the DC short circuit or the like of SCR converter can be detected assuredly, and furthermore the detection time can be reduced to almost 60°+α° (about 4ms/50Hz).

Filed: 1990-05-29
Abstract: PURPOSE:To uniformly form films of different materials on the surfaces of power- or chip-shaped magnetic substance particles by sticking the film materials while an AC magnetic field is applied to the magnetic substance particles. CONSTITUTION:When an AC magnetic field is applied to powder- or chip-shaped magnetic substance particles, magnetic coupling of the particles is cancelled and the particles are separated from one another by the action of the north and south poles of the AC magnetic field ever-changed by the magnetism of the magnetic substance particles and the separated particles move in the AC magnetic field three-dimensionally. When film materials are attached while the separated particles move three-dimensionally, the film materials are attached uniformly to each of the magnetic substance particles. For effective film formation, the frequency of the AC magnetic field is preferably 10-1,000Hz and its intensity is preferably at least 10 Oe. A frequency under 10Hz and intensity under 10 Oe separate and move the magnetic substance particles insufficiently.
