摘要： PURPOSE: To provide a structure of a light transmission body which is a light transmission body used for illumination, is formable to arbitrary shapes and allows the reduction of light loss and a process for producing the same. CONSTITUTION: This light transmission body is produced by previously providing the inside wall surfaces 3 of an upper mold 1 and a lower mold 2 with fine ruggedness and loading a hollow resin tube 4 formed by using a synthetic resin having a low refractive index to a small thickness into these metal molds, then injecting a synthetic resin 6 having the refractive index higher than the refractive index of the this tube into the resin tube 4 under pressurization. The fine ruggedness is transferred to the resin tube 4 at the time when the resin tube 4 bulges in the process of the pressurized injection of the synthetic resin 6 and the resin tube 4 comes into pressurized contact with the inside wall surfaces 3 of the metal molds. The rugged parts function to scatter light to the boundary between the resin tube 4 and the synthetic resin 6, thereby generating exit light from the entire area on the outside surface of the light transmission body.

摘要： PURPOSE:To enable the certain detection of wire breakage, by a method wherein the brightness of cable transmitted light is caught by a sensing camera and discriminated by a slice level to be divided into light and darkness at an interface while the count value of this pattern is compared with a reference count value. CONSTITUTION:Light from a light emitting lamp 10 is permeated through a multi-core flat cable 11 and the permeated image of the cable 11 is received by the line sensor camera main body 13 of a lens system 12. The camera 13 outputs this permeated image while converting the same to a video wave form. This video wave form is discriminated in a pattern selector 14 by a slice level to output the wave form as shown by the drawing. The outputs of the pattern selector 14 are counted by a pattern counter 15 to be compared with the preset pattern number of the flat cable and, when the counted value is equal to said pattern number, the cable is regarded as normality but, when it is infinitely, it is considered that there is abnormality such as the omission of a core wire and a signal is sent to the next event counter 16. This event counter 16 counts the succeeding scanning number of pattern abnormality to issue an alarm as abnormality when the length of abnormality is equal to or more than a prescribed value and wire breakage can be certainly detected.

摘要： PURPOSE:To prevent a wire from being cut by furnishing a guide rail with a group of movable sheaves as practicable to approach or go apart from the side of stationary sheave group, wherein the movable sheaves shall be capable of rotating as well as going up and down from the horizontal position with the axis of the stationary sheaves as its center, thereby eliminating risk of applying an excessive tension to the wire. CONSTITUTION:During the wire in accumulation, a group of movable sheaves 2 are pulled with a set tension same as in synchronous condition in which the incoming and outgoing speeds of the wire into/out of the accumulator, and the incoming speed is constant. However the outgoing speed decreases, and when the wire 12 is stopped, the tension applied thereto lowers below the external tension, and the movable sheave group 2 move in the direction of arrow 8 for accumulation of the wire. When out of wire, on the other hand, the incoming speed of wire into the accumulator is constant same as in synchronization and accumulation, but the outlet wire speed becomes higher than the inlet for the purpose of collection, which can be performed only under the condition wherein the tension is greater than the external tension to cause the wire 12 with increased tension, so that rotating and tilting a guide rail 3 will allow the movable sheave group 2 to move toward the stationary sheave group 1 by their own weight to lead to setoff of the increased tension, which will ensure prevention of elongation or cutting.
摘要翻译：目的：为了防止电线由一组可动滑轮提供导轨，切实可行，以便从固定滑轮组的一侧接近或离开，其中可动滑轮应能够旋转和上升，从水平位置下降到固定滑轮的轴线为中心，从而消除了对线材施加过大张力的风险。构成：在电线堆积期间，一组可动滑轮2以与进入/离开蓄电池的输入和输出速度以及进入速度恒定的同步状态相同的设定张力被拉动。然而，输出速度降低，并且当线12停止时，施加到其上的张力低于外部张力，并且可动滑轮组2沿着箭头8的方向移动以累积线。另一方面，当断线时，进入蓄能器的进线速度与同步和累积恒定不变，但是为了收集的目的，出线速度高于入口，这只能在其中张力大于外部张力，导致线12增加张力，使得导轨3的旋转和倾斜将允许可动滑轮组2通过其自身的重量朝向固定滑轮组1移动，以导致切断增加的张力，这将确保防止伸长或切割。

摘要： PROBLEM TO BE SOLVED: To provide the light transmission unit which has small connection loss between an optical fiber and a terminal transparent member and superior heat resistance and is easily assembled. SOLUTION: The core 1 of the optical fiber 3 is elastic and a core 1a which is led out of the end part of the optical fiber 1 is spliced to a terminal transparent member 4 to bring the core 1 of the optical fiber 3 and terminal transparent member 4 into contact without any gap, thereby greatly reducing the light loss of the connection part. The clad 2a at the end of the optical fiber 3 is formed in a tubular shape and the terminal transparent member is inserted into the clad 2a to facilitate the assembly and greatly reduce the light loss at the connection part. The optical fiber 3 and terminal transparent member 4 are joined together across an intermediate layer formed of transparent silicone or silicone gel to improve the heat resistance and also greatly reduce the light loss at the connection part.

摘要： PURPOSE:To constitute a multiple core flat cable by passing a plurality of extruded flat cables through oppositely arranged forming guide rollers with slits, and blowing hot air from the opposing part of the rollers to fuse a composition plane between the cables. CONSTITUTION:Two extruded flat cables 1 are passed respectively through oppositely arranged rotatable forming guide rollers 2 with slits, and hot air 3 is blown from the opposing part of the forming guide rollers 2 with slits so as to fuse a composition plane between the extruded cables 1 passing through the forming guide rollers 2 with slits. The two extruded flat cables 1 are passed through the forming guide rollers 2 with slits. An hot air generation device 4 capable of temperature and flow-rate control is provided upstream of a delivery side of a junction point of the forming guide rollers 2 with slits. The composition plane between the two extruded cables 1 is fused by the hot air 3 generated from a nozzle part of the hot air generation device 4. A fused flat cable 1a is manufactured by means of the forming guide rollers 2 with slits.

摘要： PROBLEM TO BE SOLVED: To provide a plastic light guide body unit capable of being manufactured easily and inexpensively without lowering moisture resistance. SOLUTION: This unit can be easily and inexpensively manufactured without lowering moisture resistance by using transparent resin at least in the light guide body connected to the end face of one side of an optical fiber 1. The price of the light guide body is suppressed by especially using a light guide body 2 made of glass having heat resistance in the incident part 6a of a light source side and by using a light guide body 3 made of resin in an irradiating part 6. Moreover, the unit is enabled to be manufactured more inexpensively by using acrylic resin or polycarbonate resin as the material of the resin.
