摘要： PURPOSE:To raise the yield of moldings by eliminating the deformation of and damage to moldings by using a system in which a projection is provided in the ejecting direction of the molding of the movable mold supporting the open die of molds for injection molding method in such a way as to enable moldings to be automatically dropped or taking out. CONSTITUTION:After a molding 12' is solidified by cooling, fixing metals 1-3 and movable molds 4-7 are separated at a parting face 13, and the movable mold 4 covering the molding 12' is moved toward the direction of (b) and also the central movable core 5a is moved toward the direction of (a). Whereupon, the molding 12' is supported by a supporting projection 15' and separated from the molds. In this case, the movement of the molding 12' is interrupted by the supporting projection 15' of the mold 5 provided on the periphery of the molding 12' and stayed in the same place as the molds are closed, so that products of high dimensional accuracy without any deformation can be obtained because the deviation of undercut by separation is prevented even if the central movable core 5a moves. A mechanism to retract the core 5a in the direction of (a) after retraction is also provided to the projection 15' in order to enable the molding 12' to automatically drop.
摘要翻译：目的：通过使用这样的系统来消除模制品的变形和损坏，其中在其中在支撑用于注塑成型方法的开模模具的可移动模具的成型方向上设置突起的系统一种使模制品自动掉落或取出的方法。构成：通过冷却使模具12'固化后，固定金属1-3和活动模4-7在分型面13处分离，并且覆盖模制件12'的可动模具4向（b）方向移动，并且中心可动铁芯5a也朝向（a）的方向移动。于是，模制件12'由支撑突起15'支撑并与模具分离。在这种情况下，模制件12'的移动被设置在模制件12'的周边上的模具5的支撑突起15'中断，并且与模具关闭时保持在相同的位置，使得高尺寸的产品因为即使中央可动铁芯5a移动也能够防止由分离引起的底切的偏差，所以能够得到无变形的精度。为了使模制件12'能够自动下落，也可以在凸出部15'上设置有使退回后的（a）的芯部5a退回的机构。

摘要： PURPOSE:To improve lubricating performance and the accuracy of dies, by constituting the required number of oil grooves directly and easily on a helicoid which is a sliding part. CONSTITUTION:A lens system L constitutes a part of a focusing system of, for example, a video camera or the like and is used as a camera together with the other lens system. The focusing operation is accomplished by the rotation and sliding of a helicoid 9 with the other helicoid 12 facing said helicoid. An oil groove 10 is constituted preferably to a shape deeper than the trough 9a of the helicoid 9, and is used preferably as a well for grease. Said groove may be formed simply by removing the tooth profile to the same depth as the root of the trough. The groove 10 is constituted freely on the circumference of the helicoid.

摘要： PURPOSE:To smooth focusing function and to prevent the deterioration in optical performance, by providing oil wells in the trough of a screw. CONSTITUTION:Focusing is accomplished by the relative rotation of a male helicoid 4 and a female helicoid 5, and both helicoids are slid by the intermeshing part 9 of the thread ridge 1 and trough 2 of helicoids 8. The helicoids 8 are intermeshed with each other with high accuracy for the purpose of preventing the deviation of optical paths of lens group L1-L3. The lubricating effect for smoothing the sliding movement of the part 9 is attained by the grease which is supplied gradually from oil wells 3. Since the wells 3 are formed in each trough 2 of the helicoids 8, the lubricating oil is supplied naturally to the part 9. The wells 3 function as oil wells even if the wells 3 are formed to a circular, elliptical or square shape or to the shape having the trough 2 deeper than the ordinary trough 2.
摘要翻译：目的：通过在螺丝槽中提供油井，可以平滑聚焦功能，防止光学性能的恶化。构成：聚焦是通过雄性螺旋体4和雌性螺旋体5的相对旋转来实现的，并且两个螺旋体由螺纹脊1的啮合部分9和螺旋体8的槽2滑动。螺旋体8彼此相互啮合高精度，以防止透镜组L1-L3的光路偏离。用于平滑部件9的滑动运动的润滑效果是通过从油井3逐渐供给的润滑脂获得的。由于孔3形成在螺旋体8的每个槽2中，润滑油被自然地供应到部件即使井3形成为圆形，椭圆形或正方形形状，或者具有比普通槽2更深的槽2的形状，井3用作油井。

摘要： PURPOSE:To detect cracked elements surely with simple operation and easy judgement of defectives and non-defectives by producing stress forcibly in the inside and detecting the sound from cracks. CONSTITUTION:A detector 2 has a sound detector 3 mountable to a package 1 contg. a pellet 1' which is an object to be detected, an amplifier 4, a high-pass filter 5 and a display device or deciding device 6. A circuit of the pellet 1' is constituted so as to be applied with voltages E1, E2. If a switch 7 is turned on to apply voltage to the pellet 1', the pellet evolves heat by itself and generates thermal stress. If a microcrack is produced in the pellet, the crack is progressed by the thermal stress and a sound is produced at this time. This sound is detected by the detector 2, by which the presence or absence of the crack is decided visually or by the deciding device. Only the crack progressing vibration discriminated from external vibrations is detected by the filter 5. It is equally well to utilize the on sgnal of the switch 7 for the trigger signal of the display device 6.

摘要： PURPOSE:To obtain a resin seal device of a high impregnation effect by impregnating a resin, a coefficient of linear expansion thereof is larger than that of a package resin, to a sealing body under vacuum at a low temperature in the range of 0 deg.C or less. CONSTITUTION:The semiconductor device sealed with an epoxy resin (a coefficient of linear expansion of 2X10 / deg.C) is dipped in a tank encasing Si rubber group oil (4X10 / deg.C) kept at a temperature such as -50-50 deg.C lower than the normal temperature, and vacuum impregnation-treated. Consequently, an impregnant intrudes to clearances among the header, lead and wires of the semiconductor device and the epoxy resin. The impregnant expands in the clearances during the time when it returns to the normal temperature after treatment, and clogs completely the clearances. According to the constitution, the device of high wetproofing is obtained.
摘要翻译：目的：为了通过浸渍树脂获得具有高浸渍效果的树脂密封装置，其线膨胀系数大于封装树脂的线膨胀系数，在0℃的低温下在真空下对密封体进行加热。 C以下。构成：用环氧树脂密封的半导体器件（线膨胀系数2X10 <-5 /℃）浸入包含Si橡胶组油（4X10-5℃）的罐中，保持在比正常温度低-50-50℃的温度，进行真空浸渍处理。因此，浸渍剂侵入半导体器件和环氧树脂的集管，引线和导线之间的间隙。浸渍剂在处理后恢复正常温度的时间内间隙扩大，完全堵塞间隙。根据该结构，获得了高耐湿性的装置。

摘要： PURPOSE:To provide a cam ring for a zoom lens which is inexpensive and is deformation-free by forming cam grooves on the inside of one halved cylinder of a plastic hollow cylinder consisting of a pair of halved cylinders without penetrating through the same. CONSTITUTION:Cam grooves 5, 6 are formed on the inside of one halved cylinder 4 of a plastic hollow cylinder consisting of a pair of halved cylinders 4 and 7 without penetrating through the same, whereby an intended cam ring for a zoom lens is obtained. Since the cam grooves 5, 6 are not penetrated in the cam ring obtained in such a way, the change in the groove width after formation of the grooves 5, 6 is obviated and since said ring is made of a plastic, the ring is produced inexpensively.
摘要翻译：目的：为了提供廉价的变焦镜头的凸轮环，并且通过在由一对半圆筒组成的塑料中空圆筒的一个半圆柱体的内侧上形成凸轮槽而不穿透该凸轮槽，而不会变形。构成：凸轮槽5,6形成在由一对半圆筒4和7组成的塑料中空圆筒的一个半圆柱体4的内部上，而不会穿过它们，由此获得用于变焦透镜的预期凸轮环。由于凸轮槽5,6没有被贯穿到以这种方式获得的凸轮环中，因此，形成槽5,6之后的槽宽度的变化被消除，并且由于所述环由塑料制成，因此产生环廉价。
