Title: Moving speed detecting device for object
Inventor: NONAKA OSAMU
IPC: G01C3/06
Filed: 1990-07-04
Abstract: PURPOSE:To detect the moving speed of the object at a high speed with high accuracy and to realize relatively simple constitution by finding the moving speed of the object from an integration result and a range finding result obtained by performing range finding operation plural times. CONSTITUTION:Under the control of a CPU 11, an IRED 12a is made to emit light plural times at equal time intervals. A range finding optical system 12 projects the light from the IRED 12a on the object 10 and converges reflected light from the object 10 to generate signal currents I1 and I2 corresponding to the incidence position of the converged reflected signal light. A distance arithmetic circuit 14 performs the analog processing of the output signal of a PSD 12d based upon the light projected from the IRED 12a to find the distance to the object 10. An integration circuit 15 integrates range finding results in order. A CPU 11 calculates the moving speed of the object 10 to the optical- axis direction from the range finding result ln and integration result VOUT.

Title: Pulley type power transmission device
Inventor: IKEDA EIICHIRO
IPC: F16H9/18
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To reduce an extent of machining processes and the number of part items as well as to aim at simplification of assembly operations by unifying a tension arm, a boss part and a tension shaft aftar being welded with one another. SOLUTION: A tension arm 39, a boss part 39a and a tension shaft 40 are unified into one after being welded with one another. With this constitution, a loose side span of a belt 30 is forcibly pressed, thereby forming it into a tension mechanism 38 to generate a thrust to this belt 30, and since the tension arm 39, the boss part 39a and the tension shaft 40 are handled as one unitized member, the tension mechanism 38 is well simplified in terms of structure and, what is more, a reduction in the number of part items and an improvement in assembleability are achievable. In addition, as the tension shaft 40 is not screwed in the tension arm 39, there is no looseness in this screwed part, and thus sufficient reliability is securable in the connecting part.

Title: Shock detector
Inventor: DEEBUITSUDO BOIDO RITSUCHI
IPC: G01P15/135
Filed: 1992-07-03
Abstract: PURPOSE: To provide an improved impact detector by movably setting a shaking body disposed at a non-displacing position by tension balanced with an electrostatic force to the body displacing position when an impact force of sufficient amount is applied to the electrostatic force. CONSTITUTION: When the impact force having sufficient magnitude and continuing time in upward suitable direction of an impact detector is applied to the detector, the inertial reaction and electrostatic force of a shaking body 18 become larger than the tension applied by a beam 20, and the body 18 moves toward a batch plate 16 (to the operating displacing position). In this case, switch contacts 40, 50 are closed with one another to operate the operating circuit of a passenger protecting unit. When the contacts 40, 50 are once closed, the contacts remain latched by the electrostatic force applied between conductor layers 32 and 42. After a predetermined time period, the voltage between the layers 32 and 42 is reduce the electrostatic force to the tension or less applied by the beam 20 and hence the tension returns the body 18 to the static non- displacing position.

IPC: G06T7/00
Filed: 1988-07-20
Abstract: PURPOSE: To quickly detect the defective shape of each hole of a perforated mask sheet by irradiating the mask sheet with a measuring beam and successively comparing the peak of the light transmitted through each hole with a reference value. CONSTITUTION: When an etched perforated mask sheet 10 is transferred in a sending direction 30 and reaches an inspection station, a light spot 32 is moved in the direction 28 perpendicular to the sending direction 30. When the spot 32 passes through a hole of the sheet 10, a detector 34 generates a high gray value. The signal detected by means of the detector 34 is transferred to a picture bus 38. A convoluting and integrated card (CVC) 46 receives the data and convolutes and integrates the data by forming an electronic convoluting and integrating window. An error detecting section 48 generates a reference value by averaging a series of peak signals outputted from the CVC 46. By comparing newly received peak signals with the reference value, the defective shapes of the holes are detected from the magnitude of the deviation.
