Abstract:
A pen light bulb which is self aligning in conventional pen light flashlights is disclosed. Applicable pen light flashlights rely upon pressure bearing retention of the bulb therein. A focusing lens protective element of the pen light bulb has various features which provide for a more stable seating surface thereon to contact the housing of the pen light flashlight. These features provide for the axis of projection of the beam of light from the bulb to match, or nearly match, a central axis of the pen light flashlight. A wider and larger spring contact surface on a circular base of the housing of the pen light bulb provides for a truer application of pressure by a spring to the pen light bulb to assist in proper alignment within conventional pen light flashlights.
Abstract:
A relay device for a concatenated sensor system includes first and second relay units (14, 16) and a relay cable (28) connecting the two relay units. When the first relay unit is located in intimate contact with one side of a sensor unit (8) that is situated at one end of a sensor unit group (4) or with one side of a master unit (2), a linking connector of the relay unit is connected to an input-output connector provided on one side of the master unit or on one side of the sensor unit. When the second relay unit is located in intimate contact with the other side of a sensor unit that is situated at the other end of a sensor unit group (4 or 6), a linking connector of the relay unit is connected to an input-output connector provided on the other side of the sensor unit. Thus, electrical connection between the master unit and the sensor unit group and between the sensor unit groups of the concatenated sensor system can be established with reliability.
Abstract:
A radiation sensing system for detecting electromagnetic radiation and transmitting a sensory signal therefrom includes a body, a radiation sensor inserted substantially into an outlet portion of the body, a plug inserted substantially into an inlet portion of the body, a lens placed over the inlet of the plug, and a cap secured over the inlet portion of the body. A method for making the radiation sensing system includes forming the body from an inexpensive material, forming the radiation sensor and inserting it substantially into the outlet portion of the body, forming the plug from material resistant to radiation damage and inserting it substantially into the inlet portion of the body, placing the lens over the inlet of the plug, and forming a cap and placing it over the inlet portion of the body.
Abstract:
A photoelectric switch device for detecting an object within a field of detection on the basis of a position of the object is presented. The position is determined on the basis of a value relating to light that is reflected by the object. The photoelectric switch device has a light projecting and receiving optical arrangement disposed on a front wall of a box shaped casing, a display unit and a push type of adjusting switch disposed on a rear wall of the box shaped casing. The photoelectric switch device also has a push type of selecting/fixing/setting switch and an indicator disposed on one of walls of the box shaped casing, except the front and rear walls, and an output cable extending from a corner between the rear wall and another wall opposite to the one wall. The selecting/fixing/setting switch is used to select types of information that is to be displayed on the display unit in order to set and fix the value. The adjusting switch is used to adjust the value of information displayed on the display unit.
Abstract:
The invention relates to a pressure sensor comprising a housing (12), a membrane (26) arranged in said housing and which can be deflected by the pressure to be measured, a light source (LED) having an optical axis, a light detector having an optical axis and a light blocker (36) that is coupled to the membrane and that can be deflected thereby, the blocker being arranged in the beam path of the light source. The light source and the light detector are arranged inside the housing (12), wherein their optical axes lie parallel to one another. A first prism (40) is assigned to the light source and a second prism (42) is assigned to the light detector in such a way that an uninterrupted beam path from the light source through both prisms to the light detector is obtained. To this end, the light blocker (36) is arranged between the two prisms.
Abstract:
A cylinder of the invention can precisely send out a piston rod 3 into four different positions and comprises: a spring receiving member 14 placed coaxially with piston rod 3 in a piston room (I-II) of a cylinder tube 2 so that the movement of spring receiving member 14 is limited by one end of the piston room; a first spring member 15 to separate the spring receiving member from the piston; a stopper 8 formed on piston rod 3 to limit spring receiving member 14 from moving in the opposite direction to piston 4, a hollow 9 formed on the periphery of piston rod 3 at farther position from piston 4 than stopper 8; and a stop pin 11 installed in the cylinder tube to be pressed in the direction of hollow 9 by a second spring member 12 to engage with hollow 9, wherein the movable length of piston rod 9 while stop pin 11 is engaged with hollow 9 is larger than movable distance of spring receiving member 14 from the piston. A load port and a production system of this invention are constructed using the cylinder.
Abstract:
A mounting apparatus for an optical sensor, applied to an optical scan module. A screw pile with a filet slot head, a washer and a screw nut are used to mount the base plate of the charged-couple device to the main body. Therefore, it is easy to adjust the skew in the direction parallel to the base plate of the charged-couple device and the depth of focus.
Abstract:
A semiconductor optical sensing apparatus is formed of a casing made of an electrically insulative material and having at least one opening at a bottom portion; a wiring device extending from an inside to an outside of the casing; a semiconductor optical sensor chip bonded to the bottom portion of the casing; and a connecting device for connecting a terminal of the sensor chip and the wiring device. A transparent filler is filled in a space inside the casing to cover the sensor chip, wherein the opening absorbs a volume change of the transparent filler caused by expansion or contraction thereof. A focusing device is connected to the casing and located at a position to focus an image on the sensor chip. The focusing device and casing are made of the same material or materials having substantially same thermal expansion coefficients. The semiconductor apparatus has a simple structure less affected by temperature variations and facilitates preventing deterioration and variation of optical characteristics, elongating life and improving reliability of the apparatus.
