Title: Resistance varying element
Inventor: TSUJI MASAYUKI
IPC: G01K7/16
Filed: 1988-06-27
Abstract: PURPOSE:To enable the changing of an electric resistance value at a specified temperature in discontinuity and very greatly by setting a resistance value in the extension or contraction of a shape memory alloy adapted to be extended or contracted at a specified temperature larger than the resistance value when it is contracted. CONSTITUTION:An electric resistance element is formed from a coil-shaped shape memory alloy 1. The memory alloy 1 is folded in a coil in a low temperature phase (martensite phase), where an electric resistance value thereof is low. But the alloy varies in the shape to be extended with a change in the temperature before and after a martensite transformation temperature, where the electric resistance value is very high. Thus, an electric resistance element is obtained with the electric resistance value being very high while changing in discontinuity at a specified temperature and can be used effectively for an ON-OFF control element in a temperature control circuit. Then, an alloy material and a composition ratio are changed thereby enabling the setting of a resistance change starting temperature as desired.

Abstract: PURPOSE:To prevent the interference effect of light without having a large influence on the spectral sensitivity characteristic of a photodiode by a method wherein an amorphous silicon thin film in which a p-layer, an i-layer and an n-layer have been laminated sequentially is included and the layer farthest from the light-incident side out of the layers has a specific thickness. CONSTITUTION:An amorphous silicon thin film in which a p-layer, an i-layer and an n-layer have been laminated sequentially is included; and the layer farthest from the light-incident side out of the layers forms a semiconductor visible photosensor having a thickness of 1000Angstrom  or higher. In a photodiode, the p-layer on the light-incident side has a thickness of 400Angstrom  and the i-layer has a thickness of 4000Angstrom  so as to have a peak sensitivity wavelength within a range of 550 to 560nm. However, the n-layer on the side opposite to the light- incident side has a normal and comparatively thin thickness of 300Angstrom . A fluctuation pattern by the interference effect of light is displayed remarkably on a spectral sensitivity characteristic curve on the side of a wavelength which is longer than 560nm.

Title: Plate-wave ultrasonic testing method and device
Inventor: MURAYAMA RIICHI
IPC: G06T7/00
Filed: 1995-06-27
Abstract: PURPOSE: To enhance the efficiency for determining defects by comparing the signal level of an image located within a set testing range with a specific threshold, and selecting an image which has exceeded the threshold. CONSTITUTION: If a plate ultrasonic wave is made to propagate from an ultrasonic probe placed near one of the edges of a material for flaw detection to the other edge, since an indefinite image resulting from irregular reflections caused near the ultrasonic probe is formed on one side of a two-dimensional flaw detection image, and a beltlike image caused by the other edge is formed on the other side in accordance with the dimension of the material for flaw detection, by setting a flaw detection range from an image of the other edge in the two-dimensional flaw detection image according to the size of the material for flaw detection, meandering of the material for flaw detecting, if any, can be followed.  In this flaw detection range, since the images related to the edges and the image caused by the irregular reflections exist near both ends, by setting a threshold that gets larger toward near both ends and that gets smaller at the portion halfway between the ends and by selecting an image of a signal level exceeding the threshold, images produced by defects are selected at a high rate even near both ends.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of both the underflow and overflow to increase a chip area and to suppress the power noises by varying the division rate of a dividing means, according to the frequency of an input clock signal. SOLUTION: A frequency divider 36 divides a dividing clock or an external clock signal to generate a dummy clock Z of a low level which is equivalent to three cycles at a high level, equivalent to a single cycle and inverts the clock Z to generate a reference clock X of a high level, equivalent to three cycles at a low level equivalent to a single cycle in terms of a clock signal to be supplied. These clocks Z and X are given to a selection circuit 40. Then the divider 38 divides a dividing clock or an external clock signal to generate a dummy clock Z of a low level, equivalent to two cycles at a high level equivalent to two cycles and inverts the clock Z to generate a reference clock X of a high level equivalent to two cycles at a low level equivalent to two cycles in terms of a clock signal to be supplied. These clocks Z and X are added to the selection circuit 40. A clock signal is selected, in response to an input clock signal to prevent the occurrence of both the underflow and overflow.

Title: Device for checking foreign matter
Inventor: TANIMOTO SHIYOUICHI
IPC: G01N21/88
Filed: 1981-10-09
Abstract: PURPOSE:To detect whether foreign matters are adhered on the obverse side of a substance to be checked or on the reverse side thereof by a device wherein the scattered lights are photoelectrically detected on both sides of the checked substance to check the presence of foreign matters based on the difference between both the detected photoelectric signals. CONSTITUTION:Photoelectric signals detected by a photoreceiving unit A become almost same in their levels for foreign matters (i) and (j). But a partial scattered light 1b generated from the foreign matter (i) reaches a photoreceiving unit B after passing through a glass plate 5a. The intensity of the scattered light 1b is generally smaller than that of a scattered light 1b, but photoelectric signals in some degree are generated in both photoreceiving units A and B due to attachment of the foreign matter (i). Meanwhile, the scattered light from the foreign matter (j) attached onto a shielding portion 5b will not reach the photoreceiving unit B. Thus, by measuring the photoelectric signals from both photoreceiving units A and B, it can be judged whether the foreign matter is adhered on the transparent portion or on the shielding portion.

Title: Thin film magnetic head

IPC: G11B5/31
Filed: 1985-07-22
Abstract: PURPOSE:To improve the detection accuracy of a depth length by forming a main marker film for detecting the depth length of a magnetic gap and an auxiliary marker film having the side always spaced equidistantly from one side of the main marker film in the direction of the surface to oppositely contact with a magnetic recording medium on a lower magnetic material. CONSTITUTION:The auxiliary marker film 5 is made into, for example, a trapezoidal shape and is so formed that one side 5b thereof is always spaced equidistantly from the main marker film 4 in the direction X of the surface to oppositely contact with the magnetic recording medium. The length D between respective marker films 4, 5 which expose on magnetic recording medium contact surface 6 is always to be constant. More specifically, the depth length Dp is detected by the sum of A/2 detected by the main marker film 4 and the correction value (D-D')/2 obtd. by the main marker film 4 and the auxiliary marker film 5. The depth length Dp is thus exactly detected as the detection error of the depth length Dp by the patterning error of a resist and the etching error of the main marker film 4 is corrected by the auxiliary marker film 5.
