Title: Displacement detector
Inventor: AWANO TAKASHI
IPC: G01B21/32
Filed: 1986-12-30
Abstract: PURPOSE:To always enable measurement with a high accuracy and a high sensitivity, by detecting displacement of a pair of opposed levers following the displacement of a test piece with a non-contact type displacement detection sensor. CONSTITUTION:A pair of opposed levers 1 made up of U-shaped displacement detection frames is arranged integral with a connection 2 having a thin elastically deforming part 3 at the center thereof. Following the displacement of the lever 1 and a test piece P, a non-contact type sensor 4 detects a follow-up displacement as displacement of the test piece P. With such an arrangement, elastic deformation of the displacement detection frames can be set as desired thereby always enabling highly accurate measurement without adversely affecting measuring accuracy of a load and displacement regardless of a reduction in the reaction of the lever. In addition, proper selection of sensors prevents the lowering of measuring sensitivity even when the elasticity of the displacement detection frames lowers in a high-temperature atmosphere.

IPC: G02B6/44
Filed: 1989-11-30
Abstract: PURPOSE:To widely reduce the leakage of light between optical fibers while making a reader compact and enabling high-speed reading by covering the optical fiber of an optical fiber array from a prescribed position to the end part on the photodetector array side by a light absorber without covering the optical fiber from the end part on the original picture side to the prescribed position. CONSTITUTION:The respective optical fibers of an optical fiber array 17 are covered with the light absorber and in respect to such a state, the respective optical fibers of an optical fiber array 18 are not covered with the light absorber. Reflected light from an original 10 is advanced only in the optical fibers and emitted like a figure 25 when an incident angle to the optical fiber array 18 is less than the angular aperture of the optical fiber. When the optical fiber array 17 covered with the light absorber is laminated to the optical fiber array 18, leaked reflected beams 26a and 26b are wholly absorbed by the light absorber and as a result, reading can be executed without degrading the S/N of a picture.

Title: Liquid jet device and tank cleaning
Inventor: GOTO TAKUHIRO
IPC: B08B3/02
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To prevent irregularities in cleaning such as too dense washing in an area near a liquid jet device and rough washing in an area far from the device from occurring by providing a control mechanism capable of varying a swing (angle) velocity on a swinging gyration mechanism. SOLUTION: A rotary shaft 11 is of a double construction which does not obstruct a rotating device and a first transmission gear 12 is made to ascend by manually rotating a control part 52 formed integrally with an outer lateral shaft body projecting upward from a storage part 8 and is made to descend by reversing the control part 52 through a switching mechanism. The first transmission gear 12 is disengaged with a first gear 16 by making the control part 52 ascend and in turn, is engaged with a gear for speed reduction 51, and the swing (angle) velocity of a jet cylinder part 4 which gyrates in a swiging motion following the rotation of a first operating rod 22 becomes low. For cleaning an area which is short in a horizontal distance from this liquid jet device, excess washing is controlled by appropriately moderating the jet density through accelerating the swing (angle) velocity.  On the other hand, for cleaning an area which is long in the horizontal distance from the liquid jet device, a high precision washing is performed by increasing the jet density through slowing down the swing (angle) velocity.

Inventor: TAKADA YUJI
IPC: G01C3/06
Filed: 1991-10-31
Abstract: PURPOSE:To perform highly accurate displacement measurement by successively fetching position detecting signals obtained by actuating a plurality of optical heads against an object and calculating the displaced amount of the object at every optical head. CONSTITUTION:Optical heads H1 and H1 respectively output position detecting signals H1 and I2 and I1' and I2' corresponding to the displaced amount of an object from a reference position by emitting laser beams modulated by the oscillating signal of an oscillation circuit 12 upon the object and receiving the reflected rays of light of the beams with their position detecting elements PSD. When switching contacts SWa and SWb are switched and connected to contacts N1 sides by means of a switching control section 11, the signals I1 and I2 outputted from the head H1 are transmitted to and stored in a signal processing section 10. When the contacts SWa and SWb are switched and connected to contacts N2 sides, the signals I1' and I2' outputted from the head H1' are transmitted to and stored in the processing section 10. The section 10 calculates the displaced amount of the object by solving a prescribed expression by using the signals I1 and I2 and I1' and I2' and finds a level difference (a-b).
