Title: Buried pipe probe device
Inventor: SHIYOUKAKU AKIROU
IPC: G01B17/00
Filed: 1994-05-18
Abstract: PURPOSE:To avoid failure of buried pipe due to excess excavation by detecting the magnitude of remaining vibration and probing the depth position of a resonant body in the ground. CONSTITUTION:A resonant part 2 is added nearby a buried pipe 1. A probe device 6 is scanned along the ground surface. When an antenna coil 8b approaches a marker antenna coil 5, a resonant body 3 starts vibration by the exciting signal from a transmission part 8a. If a transmission reception switching part 10b is switched in this state to the reception part 9a side, the excitation signal from the coil 8b terminates. As vibration current remains in the resonant part 2 just after the termination, it is discharged as detection signal from the coil 5. This detection signal is input in the coil 8b and received with the reception part 9a and the buried pipe 1 is detected. Based on the relative relation between the magnitude of the remaining vibration and the ground depth position, the reception part 9a probes also the underground depth of the resonant body 3 from the detected magnitude of the remairing vibration.

Title: Motor-driven camera
Inventor: AKIYAMA KAZUHIRO
IPC: G03B17/00
Filed: 1985-05-17
Abstract: PURPOSE:To reduce the load in rewinding operation and perform the rewinding operation smoothly by setting the length of a film rewound more by a spool than by a cartridge shaft. CONSTITUTION:A sprocket 36 is rotated counterclockwise through gears 25, 28, and 34 through the forward rotation of a motor 1 and the spool 2 is also rotated counterclockwise through gears 38 and 20 to take up the film 4 by one frame. When the motor 1 reverses, the cartridge rewinds the film through the sprocket 36 in reversing motion, pulleys 60 and 62, and coupling plate 95. The spool 2, on the other hand, is rotated clockwise to move the film to right, but the length of the film rewound by the spool is larger than that by the cartridge, so the film is loosened and claws 3 of the spool and the film become easy to disengage, so that the rewinding operation is carried out smoothly.

Title: Spectrum measuring device
IPC: G01J3/36
Filed: 1992-03-31
Abstract: PURPOSE:To calculate the wavelength of spectrum of a light received by a one-dimensional array-type light-receiving element by providing the one- dimensional array-type light-receiving element and a point-type light-receiving element, and measuring the change in the ratio of output intensities of the different, two kinds of light-receiving elements. CONSTITUTION:A diffracted light 6 from a planar ruled-grating 5 is spectrum- focused on a one-dimensional array-type light-receiving element 9, and a non- diffracted light 7 is collected on a point-type light-receiving element, 10. At this time, the optical thickness of the one-dimensional array-type light-receiving element 9 changes in a sinusoidal manner in relation to the wavelength when the thickness is longer than the wavelength of the light-receiving element. Thus, when an object 1 to be measured, of constant radiant intensity such as the sunlight, etc., is measured, the spectrum wavelength of the one-dimensional array-type light-receiving element 9 can be calculated by the change in the quantity of the light received by the element. Besides, by employing the ratio of the quantity of the diffracted light to the quantity of the non-diffracted light, the spectrum wavelength can be calculated without being affetected by degradation of the quantity of received light.

CONSTITUTION:An output shaft 7 is connected to a carrier 34 by squeezing a bit installed in a bit holder 8 to a member to be fastened, and moving rearward the output shaft 7 against a coil spring 67. At the same time, since a slide plate 20 and a control plate 24 are moved rearward to close the contact, power is applied to a motor 2, and a decelerating rotation is transmitted to the output shaft 7. When the fastening torque exceeds a set value in such a condition, the clutch surface 37 of an internal gear 33 in a torque limiter rotates idling while pushing back a ball 74 against a clutch spring 76. As a result, since a thrust plate 72 pushes the control plate 24 to open the contact, the motor is stopped. The output shaft 7 and the slide plate 20 are restored by the coil spring 67.
