Title: Automatic focusing device provided with correction of change in focus with temperature in camera
Inventor: YAMADA TAKEO
IPC: G02B7/28
Filed: 1983-03-02
Abstract: PURPOSE:To enable correction of the rate at which a lens formed of a plastic is extended by changing the turning amt. of a distance ring in a camera having said lens by forming a stop lever into a bimetal construction so that said stop lever is deformed by following up to temp. CONSTITUTION:The image projected by a projecting lens 18 is reflected by an object and is detected by a photodetecting lens 19. Said image is formed on a photodetector 21, then the conduction of electricity to a coil 31b is interrupted by an arithmetic circuit to release the attractive holding of a stop lever 24 and an armature 30, thus allowing the lever 24 to be turned by the force of a spring 26. The pawl part 24a of the lever jumps into the required one of the pawl teeth 8d of a distance ring 8 to stop turning the ring 8. If a member 27 of a material having the larger coefft. of linear expansion than that of the lever 24 is preliminarily fixed to the lever 24, the lever 24 is deformed so as to incline rightward at a low temp. and an overhang D is obtd. in the part 24a on the outer side of the case in which the member is shrunk by the lever 24 alone. The turning amt. of the distance ring 8 is then made smaller than the turning amt. in the stage of an ordinary temp. when the lever is detained with the pawl tooth 8d of the ring 8 meeting a required object distance. As a result, the rate at which the lens is extended by an extending cam 8b is decreased and the focal position is correctly corrected.

Title: Weld structure gear
Inventor: SHIMAUCHI YOSHINORI
IPC: F16H55/14
Filed: 1987-02-18
Abstract: PURPOSE:To reduce the generation of noise of a gear, by a method wherein a title gear has hollow closed structure formed with a gear rim, a boss, and a web, a damping material is attached to the inner surface of the web of a hollow closed part, and the damping material is used without being influenced by external atmosphere and the possibility of a drop. CONSTITUTION:By attaching a damping material 9 to a web plate, film vibration of a web 3 is reduced. In the case of a weld gear, since the generation of noise of the whole of a gear is highly influenced by vibration of the web 3, by suppression of vibration of the web 3, the generation of noise of a weld structure gear is reduced. Further, since a weld structure part formed with a gear rim 1 and a hub 2 forms hollow closed structure, the interior of the hollow part can be isolated from external atmosphere. This constitution prevents the damping material 9 from being influenced by external atmosphere, resulting in prevention of deterioration and a change of properties of the damping material 9. Moreover, a problem, wherein the damping 9 is dropped and produces a foreign matter in a gear case 6, is prevented from arising.

Title: Balance utilizing electromagnetic-force equilibrium
Inventor: KAWAMOTO AKIRA
IPC: G01G7/04
Filed: 1983-02-28
Abstract: PURPOSE:To facilitate the correction of a static magnetic field and to correct and improve the deviation in linear correlation of the current and electromagnetic force of an electromagnetic coil, by providing a DC for correcting the static magnetic field, even though a pulse current is supplied to the electromagnetic coil. CONSTITUTION:When a load is applied to a measuring pan 1, a displacement sensor 2 detects the deviation of equilibrium. A servo amplifier circuit starts the current supply to a precision-measuring electromagnetic-force generating coil 3 so as to recover the equilibrium of a balance. When the equilibrium is obtained, the current value at this time is converted into a voltage by a resistor 11. The voltage is converted into a digital signal by an A-D converter 13 and inputted to a microcomputer 29. The signal is converted into a weight value and displayed on a display device 28. When the load exceeds the range of the precision-measuring electromagnetic-force generating coil 3, a comparator 14 detects the fact that the input of the A-D converter 13 exceeds a specified value. Then a duty-ratio-determining signal generator 23 is operated according to a program stored in an ROM25 of the microcomputer 29. The operating conditions of an electronic switch 15 is changed. The duty ratio of the pulse current to be flowed to a coarse-measuring electromagnetic-force generating coil 4 is sequentially changed step by step.
