IPC: G01D5/36
Filed: 1978-07-13
Abstract: PURPOSE: To reduce the power consumption and the size of a battery by using external lights such as a natural or room light to read out the behaviour of an optically measuring scale.  
     CONSTITUTION: A device body 1, which has a rotary disc 4 formed on its circumferencial edge with a number of transparent slits as an optically measuring scale, an index scale plate 5 formed with similar slits, and a light receiving element 6 made of a photo-electric converting element such as a phototransistor, is formed with an external light inlet 2, to which a collimator lens 3 is attached. Thus, the natural light entering from the outside of the body 1 in the direction of arrow is changed through the leans 3 into a parallel beam, which is received by the element 6 through the rotary disc 4, the index scale plate 5 and the like, especially, through their transparent slits. If the rotary disc 4 is turned a preset angle, the quantity of light received is periodically varied and is measured by a meter so that the rotating speed is detected. As a result, the desired objects can be attained without requiring the light emitting lamp as a light source.

Title: Automatic form measuring method
Inventor: KUROKAWA TOSHIAKI
IPC: G01B21/20
Filed: 1980-06-25
Abstract: PURPOSE: To exclude the production of the shift program of a touch probe, by predicting the direction of the next feedback loop from at least two or more latest contact point coordinates and shifting the touch probe along the predicted feedback loop.  
     CONSTITUTION: As a probe 12 shifts on a loop 100 which is fed back to the present position, the probe 12 surely has a contact with an object to be measured at a certain position on the loop 100. Thus the next point of contact can certainly detected theoretically even though the direction 200 of the loop is set optionally. In such way, the direction 200 is predicted from the preceding data of contact point coordinates, and accordingly the next point of contact is selected normally at the position where the probe has a contact with the object 10 from nearly the direction of normal line. As a result, the entire form can be measured in a fully automatic way.

Filed: 1989-04-05
Abstract: PURPOSE:To obtain a chip resistor whose reliability is high as compared with a present thick-film precision-type chip resistor by using a gold-based electrode material as a surface electrode. CONSTITUTION:The following are provided: first surface electrodes 1 which are faced with each other at both ends in a longitudinal direction on a ceramic base 9; second surface electrodes 3 formed by baking a silver palladium paste for baking use at 600 deg.C; a resistor 2 between the first surface electrodes 1 on the ceramic base 9. The whole surface of the resistor 2 and the first surface electrodes 1 and one part of the second surface electrodes are covered with a protective film 4. Electrodes coming into contact with the resistor 2 are the gold electrodes 1, and electrodes coming into contact with a plating liquid are the silver palladium electrodes 3; they are not influenced by the plating liquid. Since the silver palladium electrodes 3 are for baking use at 600 deg.C, a crack is not caused at a boundary of a contact part with the gold electrodes 1. Thus, reliability with the gold electrodes can be enhanced; and also soldering reliability can be secured.

Abstract: PURPOSE: To simplify the scanning circuit of a gas discharge type indicator and prevent erroneous scanning of the indicator by employing an electrode connecting construction in which no more than two adjacent scanning voltages are mutually applied to respective cathode phases of the indicator.  
     CONSTITUTION: Even if an electric current is branched to an igniter discharging electrode from a cathode K k  of the same phase as the ignitor electrode to cause the adjacent cathode K 2  to become feasible to discharge at the cathode scanning time T 13  when the original igniter discharge is formed at the position of the cathode K 13  belonging to the cathode phase of a cathode phase group K ϕ1 , the scanning voltage is applied to the cathode K 14  belonging to the cathode phase group K ϕ3  to cause no voltage to be applied to the cathode K 2  at the next cathode scanning time T 14 . Accordingly, the igniter discharge is always sequentially scanned from the cathode K 13  to the original cathode K 14 . That is, when eight phases are, for example, scanned, the voltage is applied to the respective cathode phase in the order as shown at the scanning time of the cathode scanning time T 1  to T 24 .

Abstract: PURPOSE:To obtain a focus adjusting device which has no parallax regardless of the illuminance of an object, ambient temperature, etc., by switching outputs for driving a photographic lens according to whether the diameter of a light quantity stop for the photographic lens is larger than a specific value or not. CONSTITUTION:An image of an object 42 is picked up by a video camera circuit 19 and outputted as a video signal to a terminal 43.

A high frequency component comparison part 32 detects the maximum value of the high frequency component of the video signal and then outputs a signal VFY which indicates the stop or driving direction of the zoom lens 13 by the maximum value of the high frequency component of the video signal. Those two control signals VFA and VFY are inputted to a selecting circuit 38, which transmits the VFA when a stop voltage value VA is larger than the specific value, VFY when smaller to a focus adjusting mechanism 39.
