Title: Method and apparatus for measurement of residual stress
Inventor: MOCHIZUKI MASATO
IPC: G01L1/00
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To simply measure a residual stress by a method in which an object in which the residual stress exists is placed in a corrosive environment and the residual stress in the object in which the residual stress exists is converted from information which is represented by the length, the width and the direction of a generated crack. SOLUTION: An object 1 in which a residual stress exists is immersed in a corrosive liquid 2 in a tank 3 in which the corrosive liquid 2 is put, The object 1 is held in this state, the object 1 in which the residual stress exists is then taken out, and a crack is generated in a place in which a tensile residual stress exists. Since the crack is generated in a direction perpendicular to the direction of a maximum main stress, the direction of the measured stress is the direction of the maximum main stress. By using the diagram of a relationship between the crack and the residual stress, the residual stress in a place in which the crack is generated is converted. In the diagram, the product of the length of the crack multiplied by the width of the crack is set on the horizontal axis, and the relationship of the residual stress is expressed on the vertical axis.  In addition, as parameters on the horizontal axis, only the length of the crack, only the width of the crack, the number of cracks and their product are used. In addition, the diagram is prepared according to conditions such as the material of the object 1, the solute of the corrosive liquid 2, the corrosion time, an environment and the like.

Title: Lens barrel
Inventor: OGAWA TAKAO
IPC: G02B7/04
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To easily improve the durability, impact resistance and soundproofing in a drive transmission part of an optical element by providing air holes at positions noncoinciding with a cum groove of a fixed barrel in the both end areas of a movable range of a lens barrel room, at the position coinciding with the same in the central area on a rotary barrel. SOLUTION: Exchange of air is performed from/to the outside of a rotary barrel 6 through cum grooves 42 formed on the fixed barrel 4 and the air holes 6c formed on the rotary barrel 6 as the rotary barrel 6 goes from the infinite side to a closest distance side. As the rotary barrel 6 turns to the closest distance side, the air holes 4c are closed again and an air pressure in a space consisting of first group, second group barrel rooms is increased to become resistance for first group drive. When impulsive force is applied to a connection gear and an inner tooth at an AF time, it is absorbed by circular rubber, vibration and, impulse due to inertia are absorbed by elastic rubber when the first group is driven and a sound at a collision time is reduced by a rotation control pin at the time of arriving at a terminal end.  In such a case, the air holes 6c are arranged so that an air spring is operated at the time of colliding with the terminal end part of the infinite side or the closest distance side so as not to receive the resistance of air in the vicinity of the middle.

IPC: B21D26/021
Filed: 1994-06-23
Abstract: PURPOSE:To enable the formation into an optional shape by clamping the sur rounding of an aluminum-made roll-bond panel before pipe-expanding and execut ing the pipe-expansion work in the clamping condition after forming by an opposite hydraulic forming method. CONSTITUTION:The aluminum-made roll-bond panel material 1 is laid on a lower die 3 incorporated with liquid 2. Both ends of the panel material 1 is clamped with the die 3 and a blank holder 4, and a punch 5 is lowered. The panel material 1 is applied with the pressure of the punch 5 from the upper side and the pressure of the liquid 2 from the lower side and formed along the shape of the punch 5. The punch 5 is further lowered to execute the deep drawing to the panel 1. The pipe expansion work is executed to the panel material 1 by feeding the air having higher pressure than the pressure of the liquid 2 in the clamping condition of the panel 1. This method can be executed by manufacturing only one side of the die, and the die cost can be saved.

Abstract: PURPOSE:To obtain a bearing capable of being used under a high load and high temp.  condition, by a method wherein an element showing special compatible effect such as  Mn or Fe is added to an Al alloy containing tin for the bearing of an internal combustion engine and the dimension and the distribution density of a particle formed by adding said element is specified. CONSTITUTION:An Al alloy containing, on the basis of wt% 1-35 Sn, 0.5-11 one or more of Mo, Ni, Zr, Co, Ti, Sb, Cr and Nb and substantially comprising the remainder  Al is bonded to a backing metal to obtain a bearing. 5 or more particles per 3.56X 10<-2>mm.<2> consisting of >one kind of aforementioned elements and having 5-40mu length  are contained in the optional parts of the alloy of the bearing, which can be used  without an overlay. In this case, when the added element is below the lower limit,  special compatible effect which contributes to the flattening of recessed and protruded  parts of a partner material becomes defficient and, when exceeds the upper limit, said  effect is not enhanced and the lowering in fatigue strength and baking load is apt to  be generated. When the length of the particle is below the lower limit, the special compatible effect is not exhibited and, when exceeds the upper limit, fatigue strength is  lowered. As to the distribution density of the particle, when it is below the lower limit,  the special compatible effect is not recognized.

Title: Measuring apparatus of distance
Inventor: KOYAMA TAKASHI
IPC: G02B7/32
Filed: 1990-06-20
Abstract: PURPOSE:To enable execution of distance measurement free from parallax by a method wherein lights from a plurality of light sources are projected through a first lens unit when ordinary distance measurement is executed, while they are projected through a second lens unit when a distance to a main subject is within a prescribed distance. CONSTITUTION:A main lens unit 4a of a projection lens 4 is adjusted in parallax in relation to an objective lens 2 of a finder in an ordinary state, light fluxes from light sources 6a to 6c are projected toward a subject through the lens unit 4a and thereby multipoint distance measurement is conducted. In the case of ordinary distance measurement, a distance-measuring operation on the basis of a light-sensing element 7d is put off. In the case of distance measurement for an object located at a short distance, on the other hand, the objective lens 2 is moved for correction in parallax in relation to an image pickup lens 1, while the distance-measuring operation on the basis of the element 7d is started. At this time, emission from the light sources 6a and 6b is prohibited. In projection, the light flux from the light source 6c is directed also to a subject 3 in proximity through a subordinate lens unit 4b. A reflected light from the subject 3 located at a short distance is led to the element 7d for proximity image pickup through a reception lens 5 and the distance to the subject 3 is measured in accordance with a triangulation algorism.

The recognition for the unit of a character is performed to this image and when one candidate can be fixed, that candidate is displayed in a block letter β. Afterwards, when the 'KU' can be fixed by post-processing, this is also turned to block letter display γ (figure C). Thus, a since the non-fixed character is displayed in the image, the erroneous recognized candidate can be prevented from being displayed.

SOLUTION: When a screw groove of a screw shaft 22 is being ground by a grinding wheel 30, the shaft 22 is elongated by heat caused by the machining. Since a chuck side of the screw shaft 22 is bound, the elongation occurs on a tailstock 21 side and is reflected as rearward travel amount of a slide shaft through a tailstock center 18 in accordance with it, and travel amount of the slide shaft is detected by a detector 16. This detected value is input into an NC device 28 through an amplifier 32. In the NC device 28, a command to which compensation is added is sent to a servo motor 26 for driving table and a servo motor 27 for driving main spindle.
