Title: Eccentricity measuring apparatus for lens system
Inventor: ARIGA SUSUMU
IPC: G01M11/00
Filed: 1988-10-07
Abstract: PURPOSE:To enable complete correction of misalignment of a collimator lens for measurement by determining a deflection of a reflection image from a lens system to be measured with respect to a reference axis. CONSTITUTION:A measuring apparatus 1 is made up of a light source 2, a capacitor lens 3, an indicator 4, a semipermeable mirror 5, a collimator lens 6 for measurement, a lens system 7 to be measured, an imaging surface 8, a semipermeable mirror 9 composing an optical system for setting axis, an image rotator 10, a collimator lens 11 and a reflecting mirror 12. In measurement, the light source 2 and the collimator lens 6 for measurement are adjusted to project the indicator 4 on a surface to be measured of the lens system 7 to be measured. Then, coordinates are determined for a reflection image of the indicator 4 on the imaging surface 8 while the image rotator 10 is turned to adjust the light source 2 and the collimator lens 11 so that the reflection image of the indicator 4 is projected on an image 8 formed to determine coordinates of the center of rotation. Then, a deflection is determined from a coordinate difference therebetween. This enables complete correction of misalignment of the collimator lens for measurement.

Title: Fluid control valve
Inventor: FURUNO TAKETO
IPC: F16K11/07
Filed: 1988-10-07
Abstract: PURPOSE:To jointly use switching by a solenoid and switching by pilot pressure by passing a main spool through a sub-spool and freely moving both spools relatively in a fluid control valve for switching a spool to control a passage for a fluid. CONSTITUTION:A sub-spool 22 is disposed in a valve main body 1 in such a manner as to freely slide, a main spool 6 is passed through the sub-spool 22 in such a manner as to freely slide, and the sub-spool 22 is usually kept in the neutral position by springs 27, 28. When one solenoid is excited, with pressure in pilot chambers 23, 24 kept to the tank pressure, only the main spool 6 is switched while the sub-spool 22 is still in the neutral position, so that a piston of a cylinder 19 is moved to the right. Further, pilot pressure is introduced into one pilot chamber 24 while with both solenoids still in the non- exciting state, only the sub-spool 22 is switched while the main spool 6 is still neutral, so that the piston is moved to the left. Thus, both a solenoid system and a pilot system can be used by one control valve.

IPC: F02D41/02
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To effectively prevent torque shocks in changing over an engine between an operation on its full cylinders and an operation with its cylinders halted. SOLUTION: In order to prevent torque shocks in changing over an engine from an operation on its full cylinders to an operation with its cylinders halted, an electronic air control valve(EACV) is opened as well as an injection quantity Ti and ignition timing θIG are controlled on the basis of an actual intake back pressure Pb detected by a detector means. Since the use of an actual intake back pressure Pb at transition in the changeover complexes proper control, an injection quantity Ti and ignition timing θIG are controlled on the basis of a predicted intake back pressure Pb stored in advance at a shifted position precedent to the changeover point by a delay period B.  That shifted point is returned to the original control using an actual intake back pressure Pb when the actual intake back pressure Pb becomes equal to the predicted intake back pressure Pb after the completion of the changeover.

Title: Locking condition detecting device of connector
Inventor: KODA TOMOYUKI
IPC: H01R13/639
Filed: 1988-10-12
Abstract: PURPOSE:To make the detecting work easier as well as to reduce the manufacture cost by providing a detecting device to detect the position of the bending direction of a locking arm set to a connector. CONSTITUTION:After a lock detector 23 has been set, the light emitted from a light source is radiated to a connector side from a projector tube 39 of an optical fiber 33. In this case, when the connector is locked adequately, the light radiated from the tube 39 is reflected by a projection 9 for locking, and the reflected light quantity incident to a tube 41 for light receiving is made 100%, a photoelectric switch 38 outputs the signal, and an output device outputs the OK signal. When a male connector 3 is not pushed in sufficiently and the projection 9 is at the near side of a hooking member 19, the radiated light is reflected at the upper side of the base side of an arm 7. In this case, the interval Y between the tip 35 of the optical fiber and the arm 7 is larger than the interval X in the regular locking condition. As a result, since the reflected light quantity incident to the tube 41 does not reach 100%, the photoelectric switch 38 does not output the signal, and the output device outputs the NG signal.
