Filed: 1995-02-10
Abstract: PURPOSE: To measure an object with high accuracy regardless of the shape of plane to be measured by detecting the interference fringe while varying the relative positional attitude between the object having the plane to be measured and an interference optical system by a predetermined amount at a time. CONSTITUTION: Light from a coherent light source 1 is expanded through an expander lens 2 and passed through a collimator lens 3 to produce parallel light which passes through a half mirror 4 and reaches a wave front converting section 5. The light irradiates an object 6 to be measured with a wave front similar to the plane to be measured and reflected toward the half mirror 4. The light from the light source 1 reflected on the half mirror 4 is further reflected on a reference mirror 7 toward the half mirror 4. Two lights are superposed on the half mirror 4 and reaches an interference fringe detecting section 9 where the interference fringe is observed.  The relative positional attitude between the object 6 and the wave front converting section 5 is then varied and the interference fringe generated for each partial area of the plane 6a to be measured is detected at each relative positional attitude. Finally, these interference fringes are combined to create the interference fringe on the plane to be measured.

Abstract: PURPOSE:To measure the density of smoke at multiple points by allowing one light emitting device to emit light at continuously varied wavelengths and branching the light thereof to a plurality. CONSTITUTION:The light obtd. by the light emitting device 1 is sent to an optical branching filter 3 via an optical fiber 2. The branched light rays A, B which are obtd. by the optical branching filter 3 and vary in frequency in an f0 to fm range are transmitted via an optical fiber 4 to an optical BPF 5, through which only the light rays of the specific frequencies are passed. The branched light rays A, B of the frequencies fA, fB past the BPF 5 are respectively collimated by a collimator lens of a light projecting side optical system 6 to collimated beams of light. These beams propagate in the space where a measuring object, such as smoke, exist. The light is shut off according to the density of the smoke, etc., during this propagation and the quantity of the light is thereby attenuated. The attenuated light is then condensed by a lens 7 of a light receiving side optical system and is projected via an optical fiber 8 to an optical coupler 9, by which the branched light rays A, B are again coupled and are transmitted via an optical fiber 10 to a light receiving device 11. The respective light rays A, B are photoelectrically converted in the light receiving device 11, by which the density thereof is detected.

Title: Reference signal generating circuit
Inventor: URAGAMI TOYOZO
IPC: H04N5/10
Filed: 1989-01-31
Abstract: PURPOSE:To simplify the constitution of a reference signal generating circuit by changing a set value from a value slightly longer than a vertical synchronizing cycle to another value corresponding to the vertical synchronizing cycle when vertical synchronizing signals, the number of which is more than a certain number, are continuously omitted. CONSTITUTION:When the vertical synchronizing signals are inputted, the value slightly longer than the vertical synchronizing cycle is set, and when the vertical synchronizing signals are omitted, a compensatory signal is generated. When omitted synchronizing signals, the number of which is more the certain number, are continuously omitted, since the compensatory signal is outputted in a cycle equal to the vertical synchronizing cycle, the compensatory signal can be used as a reference signal when the synchronizing signals are not inputted. Thus, in the constitution for compensating the omission of the vertical synchronizing signals, the circuit can operate as a reference signal source by changing the set value, and the constitution can be simplified.

Title: Leakage detector
Inventor: HONDA KAZUYOSHI
IPC: G01R31/02
Filed: 1978-02-28
Abstract: PURPOSE: To ensure the leakage protection even during the phase missing, by rectifying the output of zero-phase current transformer and charging a capacitor then detecting the level of said charging voltage at a switching circuit.  
     CONSTITUTION: Series circuit of diode D1 and capacitor C1 is connected across the coil of zero-phase current transformer ZCT while another series circuit of trap coil TC and swtiching element S is connected across said capacitor. Consequently when a leakage occurs to cause unbalanced current, voltage is induced in the output coil of ZCT to change the capacitor C1 and when said voltage reaches to the breakover voltage of the switching element S1 it is conducted to drive the trip coil TC. Since the tripping is performed by the energy stored in ZCT, the leakage protection is performed reliably even when one line is missed.
