Title: Rotary driving device
Inventor: SATO ICHIRO
IPC: B62M3/06
Filed: 1990-01-10
Abstract: PURPOSE:To improve the efficiency and enable the use for generater or the like in a rotary driving device of a bicycle or the like by fitting an input gear, a compound gear, an internal tooth type output gear and a large diameter stator internal gear to a main shaft in this order, and engaging one of the compound gear with the input gear and the other with the stator internal gear respectively. CONSTITUTION:The rotary driving force to be applied to a crank arm 2 rotates a main shaft 1 through an input gear 3. An external gear 9 is thereby rotated at high speed. External gear 10 that is one body with the gear 9 is rotated with the rotation of the external gear 9, and tries to rotate a stator internal gear 16 for drive. But the internal gear 16 is fixed not to be rotated, the external gear 10 rotates by itself in the inner periphery of the internal gear 16 to be revolved against the main shaft 1 in the direction reverse to the self-rotating direction. Consequently, external gears 11, 12 rotate at high speed, and the rotating force is returned to the crank arm 2 through the external gear 10 is reduced the input. With this structure, an output gear can be driven efficiently.

Title: Multiprogrammed shutter
Inventor: NAKAGAWA TADASHI
IPC: G03B9/24
Filed: 1986-01-09
Abstract: PURPOSE:To improve the operability of a full-automatic camera by switching the rotating speed of a motor to a fast or slow speed according to a selected program. CONSTITUTION:When a photograph is taken through a telephoto lens with which a fast program is effective, a user operates the program changeover switch (not shown in figure) of a camera body to set a frequency division ratio from a frequency dividing circuit or the voltage of a voltage adjusting circuit so as to rotate the driving motor 4 at the preset fast speed. When a release member (not shown in figure) is pressed down in the state shown in the figure, a main switch turns on immediately and the driving motor 4 begins to rotate clockwise at the fast speed to run a driving plate 1 to the left. Consequently, the driving plate 1 drives a scan lever 5 for focusing detection by its cam part 1c, and consequently while focusing is detected by this lever 5, the photographic lens (not shown in figure) is set at the focusing position.

Abstract: PURPOSE:To reduce high-frequency loss, by connecting a capacitor for cutting off DC component in series to a load. CONSTITUTION:With the 1st-2nd switching elements (Tr) Q1...Q2 connected to a DC power source E the power supply is ON and OFF. These Trs Q1-Q2 are alternately driven by a drive circuit 1.

Abstract: PURPOSE:To enable a locating device to be economically and accurately controlled by feeding back controllably the total displacement of a main drive system and fine displacement drive section and the difference between said total displacement and the input amount of the fine drive section respectively to the fine drive section and the main drive system. CONSTITUTION:Only a distance C is mesured and fed back to a piezo-element 7 to control the piezo-element 7 according to the difference D between a command value R and the distance value, while a value F of the distance C minus the displacement of the piezo-element 7 is fed back to a motor 4 to control the motor 4 by the difference G between the value F and the command value R. Thus, the relationship of position of a table 2 + displamcement of piezo-element 7=C=R is established, while the control is carried out so as to provide R-R=O and F=C-E so that E=O is obtained and the table 2 is controlled to reach approximately the command value. The correction amount the due to the piezo- element 7 becomes so fine that it does not exceed a stroke. And since the final position is fed back, the accuracy in location can be improved up to the error of a measuring machine and the minimum displacement of the piezo-element.

IPC: G11B3/12
Filed: 1979-01-12
Abstract: PURPOSE: To secure the high-accuracy detection for the stylus pressure load of the pickup cartridge and then give the optimum stylus pressure to the pickup device by extracting the stylus pressure of the pickup cartridge in the form of the electric signals via the semiconductor stress element.  
     CONSTITUTION: p-Type silicon semiconductor element 23 is attached to substrates 24 and 24 each which are adhered to both surfaces of cantilever 21. Thus element 23 forms the bridge circuit along with resistances 25 and 26. Then power source 27 is connected between connection points A and B of the bridge circuit along with meter 28 connected between connection points C and D respectively. With application of the stylus pressure load to lever 21, output voltage V is caused between points C and D. As a result, the pointer of meter 28 swings for readout of the stylus pressure. The balance can be secured for the bridge circuit with increase/ decrease of resistance R 3 , and thus the zero-adjustment is possible for the meter. Thus the high-accuracy measurement becomes possible for the stylus pressure load of the pickup cartridge.
