Title: Method for evaluating plastic molding
Inventor: WATABE JUN
IPC: G01B11/00
Filed: 1995-02-13
Abstract: PURPOSE: To evaluate the surface accuracy and perpendicularity of a plastic molding having two adjacent planes efficiently with high accuracy. CONSTITUTION: Laser light from a laser interferometer impinges on the planes 2, 3 of a plastic molding, e.g. a roof mirror or a prism, having a right angle ABC defined by two adjacent planes 2, 3. The object is positioned such that the incident laser light 11 is reflected on two planes 2, 3 and the reflected light 12 makes right angle to a laser interferometer thus causing interference between the wave front of the reflected light 12 and the wave front of of reference light reflected on the reference plane in the laser interferometer. When an angular error of (Δθ/2) is present in each of the perpendicular planes 2, 3 of the object, as shown by 2a, 3a, and the phase difference between the reflected light and the reference light is Δλ, the angular error can be represented as follows; Δθ=(2/D)×Δλ. An interference fringe pattern is generated based on this principle and the wave aberration is measured. Finally, the relationship between the profile of wave front and the perpendicularity is determined and the surface accuracy and perpendicularity are evaluated based on the profile of wave front.

Abstract: PURPOSE:To compress an information quantity, to reduce a color noise and to attain a picture expression easy to see by applicably limiting the number of colors according to the attribute of an objective picture. CONSTITUTION:The frequency of each color of an input picture is added successively from the color of a maximum frequency, compared with a threshold value, the frequency-added number of colors is determined as a representative color by the time when the added value of the frequency exceeds the threshold value and the colors of each picture element ot the input picture are encoded by the index of the representative colors of the quantity of the number of the representative colors. Here, the threshold value is changed in accordance with the number of colors added by the time point of a comparison with the added value. For example, the multiplied value of a variable coefficient changing depending on the number of colors by the comparison time point by the full prime numbers of the input picture is made as the threshold value. Processings from a histogram preparation to an encoding are executed by the program processing of a central processor 104 and the input picture is executed by an image scanner 100 under the control of the central processor 104. Thus, the number of colors is limited applicably to various kinds of color pictures, the information quantity is compressed and simultaneously the color noise can be reduced.

Abstract: PURPOSE:To adjust the quantity of light excellently with superior reproducibility even when energy quantity at every pulse is fluctuated by variably constituting the closing working speed of a shutter means, controlling the closing working speed or time width and adjusting the quantity of light. CONSTITUTION:The time until a shutter completes closing operation thereof from the eighth pulse is represented by the sum (tb+Tbeta) of the lag time tb and the time width Tbeta of a fall section until perfect shielding after the actual shielding start of laser luminous flux by the shutter (closing operation time width). A section regarding the working speed of a mechanical system in the lag time tb and the fall time Tbeta can be varied by controlling the working speed of the shutter. Consequently, when closing operation time width is kept within the range of variably controllable closing operation time width (tb+Tbeta), the quantity of shutter transmitting energy during said closing operation time width can be altered by controlling the speed of the shutter. Accordingly, the quantity of light can be adjusted excellently with superior reproducibility even when the quantity of light or energy disperses at every pulse.

Abstract: PURPOSE:To upgrade the high frequency characteristic by enabling the formation of emitter regions having narrow width, by a method wherein the window width is narrowed by oxidizing the part of a polycrystalline Si substrate exposed to the inner wall surface of an emitter-forming window. CONSTITUTION:After a P-type base region 9 is formed in an N-type Si substrate 8 serving as the collector region, a polycrystalline Si film 10 is formed over its surface, and an Si nitride film 11 further thereon. Then, an emitter-forming window 12 penetrating through these films is formed. Next, the Si substrate is heat-treated in an oxidizing atmosphere, thus oxidizing the end surface of the Si film 10 and the surface part of the Si region 9 which are exposed in the window 12, resulting in the formation of an Si dioxide film of about 3,000Angstrom  thickness. Of this, the portion of Si dioxide film lying at the window bottom is anisotropically etched by reactive ion etching. This treatment makes only the Si dioxide film 13 formed at the end surface of the Si film 10 remain inside the window.

The curvature radius r3b at the inner side of the crest 33 is made smaller than the radius r3a by the thickness of the screw part, and the curvature r3b at the inner side is made relatively larger than the radius r3a by the thickness of the screw part. By this construction, the radius r3b can be made relatively large, and prevented from extremely reducing with respect to the radius r3b, and the curvature of the crest and that of the root at the inner side surface of the screw part 11 are not varied so rapidly. Therefore, no compression strain is not generated at the screw part 11 and the generation of cracks can be prevented.

Abstract: PROBLEM TO BE SOLVED: To surely sense an incoming alarm by a carrying person even when there is no margin for the occurrence of malfunction and further in the case of under a noisy environment or violent action and to unnecessitate a stop operation for stopping the alarm operation. SOLUTION: An incoming alarm system 1 is composed of an incoming detection part 13 for outputting a control signal when there is an incoming call to a housed portable radio telephone, power source part 14, portable housing case provided with a switch part, alarm mechanism 30 such as a vibrator, and the line from 50cm to 120cm for the terminal connection of them. First of all, when there is an incoming call, the control signal is applied from the incoming detection part 3 to the switch part, the switch is turned on, and driving power is supplied from the power source part 11 to the alarm device 30.  Thus, since a received electric field gets lower than a threshold value when a user detects the incoming call and takes the portable radio telephone set out of the portable housing case 10, the control signal from the incoming detection part 13 is turned into '0', the switch part is turned off, and the supply of power to the alarm device 30 is cut off.
