Title: Capacity detector
Inventor: KODERA YOSHITAKA
IPC: G01R27/26
Filed: 1978-03-10
Abstract: PURPOSE: To prevent malfunction and make possible sure detection by making the electrostatic capacity between counter electrodes constituting a part of the electrostatic capacity of an oscillation circuit adjustable to an optimum detection state with the dielectric factor of the object to be detected by making the opposing area or distance of the electrodes variable.  
     CONSTITUTION: A counter electrode 1 comprises opposing a movable electrode plate 1a and a stationary electrode plate 1b and making the opposing area variable through rotation of the movable electrode 1a. The movable electrode plate 1a is connected to the collector of the TrT 1  of an oscillation circuit 3 and the stationaly electrode plate 1b is connected to terminal θ. The oscillation circuit 3 forms a Colpitts oscillator circuit with a coil L, split capacitors C 1 , C 2 , TrT 1 , feedback resistance R 4  and its oscillation output is connected from the collector of T 1  to the base of the T 2  of an osicllation state detecting circuit 4. The output from the emitter is connected to output terminal E. When the liquid level of the object to be detected 2 rises and makes contact to the electrode plates 1a, 1b, the electrostatic capacity between these increases, resulting in the increased electrostatic capacity of the oscillation circuit 3. When thi changes with the oscillation conditions and the oscillation stops, the T 2  goes off and the DC voltage which had so far existed at the output terminal E goes OFF, thus indicating the detection of the object to be detected 2.

Title: Motor-driven camera
Inventor: HARAGUCHI SHOSUKE
IPC: G03B17/00
Filed: 1988-02-08
Abstract: PURPOSE:To eliminate hourly loss by driving both a spool and a sprocket when film is loaded and switching only the spool to driving afterwards. CONSTITUTION:A film winding transmission system is divided into a route for the spool 52 and that for the sprocket 58. The route for the sprocket 58 is provided with planetary clutches 40 and 46, and a holding mechanism 60 holding a planetary lever 44 when it slightly rocks in the non-engagement direction. The unidirectional rotation of a motor M1 enables a sprocket-free state, and the reverse rotation of the motor M1 can drive other mechanical driving transmission systems. Thus, hourly loss is eliminated, and film winding is accelerated.

Filed: 1978-03-14
Abstract: PURPOSE:To always enable a sliding movement at a constant speed even if ambient temperature changes, by specifying material of a fixing axis and a gear. CONSTITUTION:A fixing axis 24 fixed in a fitting base plate 23 is made of such a material having a large thermal expansion coefficiency as plastic and so on, and a cylindrical gear 25, which is rotatably located at an outer circumference of the fixing axis 24 through the medium of a space, is made of a material, such as a metal and so on, having a smaller thermal expansion coefficiency than the fixing axis 24. And thus, when the ambient temperature lowers, a space between the fixing axis 24 and the gear 25 becomes wider, and the gear 25 easily rotates due to the rotation of a driving gear 28 in spite of a low temperature. If the ambient temperature rises, the space between the fixing axis 24 and the gear 25 becomes narrower, and a sliding resistance becomes large. This causes the gear 25 not to rotate any faster than is necessary, and causes an expected purpose to be achieved.
