Abstract: A position detection element 4 is formed by sequentially depositing an X-axis resistor film 5, a photoconductive film 6 and a Y-axis resistor film 7 on one surface of a glass substrate 2 which is a transparent member. Further, a light screening film 3 is formed on the other surface of the glass substrate 2. At that time, a pin hole 31 through which light is transmitted is formed at a central portion of the light screening film 3. Where the position detection element 4 and the light screening film 3 are formed integrally with and on the glass substrate 2, mounting of the glass substrate 2 on a casing of a sensor enables the position detection element 4 and the light screening film 3 to be mounted on the casing of the sensor, thus improving the mounting property of the light position detection element 4 and the light screening film 3 on the casing.

Abstract: An insolation sensor for detecting a substantial insolation direction from the sun including a light shading film an aperture defined therein and provided on one of the surfaces of a glass substrate. A position detection element having a photoelectric conversion film made of a semiconductor is formed on the other surface. The rays of light from the sun are incident as a spot beam H onto the position detection element through the aperture. The position detection element detects a center of the intensity of photocurrent at the beam receiving portion. Therefore, even when the intensity of each of the direct rays and scattered rays from the sun change on the ground depending on the weather conditions, the center position of the distribution of the insolation intensity can be detected in accordance with the weather conditions, and a substantial insolation direction can be detected.

Abstract: A button feed tape used to supply buttons for a button stitching machine comprising an upper sheet and a lower sheet with the buttons sandwiched therebetween. The upper and lower sheets provide openings to expose the buttons and to allow easy separation of the sheets from the buttons after the buttons are stitched. The button feed tape is fed by sprocket holes provided along the sides of the button feed tape.

Abstract: A game machine has a plurality of targets which unpredictably come out and disappear from their corresponding holes at the surface of a table on a game stand. A player can only strike targets which are positioned above the surface thereof. A main shaft is provided with the target on its upper end and is supported by bearings in such a manner that it can rotate and move up and down. A plunger disposed at the periphery of the main shaft is magnetically attracted by an electromagnetic solenoid. When raised, the main shaft always faces a predetermined direction due to an action of permanent magnets. Hitting of the target can be detected by monitoring abrupt large fluctuations in current flowing through the solenoid during a period of time that the target is caused to appear above the table.

Abstract: A machine adapted to produce on a screen images of a road and motor vehicles, not under the control of an operator of the machine, which run over the road while changing lanes thereover. An illusion of motor vehicles changing lanes while running over the road can be created by the relative movement of a road image forming means represented on a rotary disk and motor vehicle models supported by a rotary body, such relative movement taking place across the width of the road forming means.

Abstract: A foam glass is manufactured by mixing silicate glass, a volcanic glass material (volcanic ashes of a special chemical composition, occurring in the Kyushu District of Japan), water glass and at least one member selected from the group consisting of sodium salts and calcium salts of phosphoric acid, firing the resultant mixture into a fused state and cooling the fused mixture. The foam glass has a high aluminum content, contains numerous fine bubbles less than 1.5mm in diameter, has a bulk density of less than 1 and shows excellent mechanical strength such as, for example, high bending strength.
