Abstract: PROBLEM TO BE SOLVED: To touch and fix a contact to a land pattern formed on a PCB without soldering by providing a contact to be mounted on the surface of the land pattern with elasticity in the vertical direction. SOLUTION: A contact 202 which is mounted on the surface of a land pattern 211 formed on a printed circuit board 210 an formed to have elasticity in the vertical direction is fabricated by being inserted into a housing 201. In this case, the end 203 of the contact 202 is molded into a projected square shape or into a hook-shape, namely, a J-shape, so as to facilitate its contact with the land pattern 211. The contact 202 is thus mounted on the surface of the land pattern 211 formed on the printed circuit board 210 and can touch the land pattern 211 without being soldered to the printed circuit board 210 nor using a separate-body receptacle, so that this constitution can prevent the occurrence of a short circuit, etc., caused by the soldering.

Abstract: PURPOSE:To make sure the movements of a land mine which keeps its end faces always in the direction of up-and-down by providing the upper and lower faces of the land mine which has a circular cross section and the thickness shorter than the diameter with an ultra sonic wave receiver which sends ultrasonic waves in the vertical direction and dropping the land mine from a moving body always with the upper and lower end faces lying in the up-and-down direction. CONSTITUTION:A scatterable mine has a shape of cylinder which has the height shorter than the diameter. Consequently, when it is dropped form a helicopter, etc. either end face of the upper and lower end faces upwards when it lands the earth. Those upper and lower end faces are provided with ultrasonic wave transmitting and receiving devices 11 and 21 respectively, and the ultrasonic waves are sent perpendicularly to the end face and outwards. The echo of an ultrasonic wave that is sent is limited in a certain range and this range is the range of detection. For instance since the transmitting and receiving device 21 on the lower side is in contact with the ground surface, the echo is made ineffective and the transmitting and echo of receiving device 11 on the upper side becomes ineffective when the distance to an object which is supposed to be subject to the mine explosion is over the range of detection. As a result, only when an object to be hit by mine comes in the range of detection the explosive is actuated and the destruction of the object becomes certain.

Filed: 1995-02-24
Abstract: PURPOSE: To read an image having a high contrast and a high definition, to easily handle a device, and to eliminate a bad influence upon a control system and peripheral mechanisms by using a laser light source as the light source of read light. CONSTITUTION: The laser light source like an argon laser 80, a krypton laser, or a helium-cadmium laser is used as the read light source. For example, the argon laser 80 is used as the light source to emit the light whose wavelength is 488nm, and this light beam passes a pinhole 81 and is expanded by a magnifying lens 82. The expanded laser light illuminates the face of a liquid crystal recording medium 20 with a prescribed spread as convergent light by an illumination lens 7. The image of transmitted light modulated by the liquid crystal recording medium 20 is formed on a CCD sensor 75 by an image forming lens 74 and is converted to an electric signal. Thus, image read data having a high contrast and a high definition is obtained.  Further, the laser like the argon laser 80 is easily handled and doesn't require a high voltage required for a xenon light source and has no influences upon the control system and peripheral devices.
