Title: Transmission circuit for optical wavelength multiplex transmission
Inventor: TAKAHASHI MASAAKI
IPC: H01S3/23
Filed: 1988-04-11
Abstract: PURPOSE:To realize small size and low cost by constituting the circuit by plural laser diodes connected in series through a guide path, light is emitted in different wavelengths by a driving signal where other laser diodes are light-emitted by an injected wavelength by the injection of its output light when one laser diode is driven and light-emitted. CONSTITUTION:For example, a laser diode LD10-1 is set in the ON state by a control signal from a time division multiplex circuit TDM 95, lighted at a wavelength lambda1 and diodes LD10-2-10-5 are set in the OFF state. Then an electric signal is fed from a driving circuit 90-1 to the LD10-1 to convert the signal into an optical signal and the output light is injected sequentially to the diodes LD10-2-10-5 via a waveguide, they are lighted sequentially by the wavelength lambda1 and the output light of the LD10-5 is sent to an optical fiber via a lens 60. When the LD10-2 is set in the ON state and the other diodes LD10-1, 10-3-10-5 are set in the OFF state, the output light of the LD10-5 is sent to the optical fiber similarly. However, it is controlled that two LDs or over are not simultaneously turned on by time division multiplex processing by a TDM 95.

IPC: F16F13/18
Filed: 1984-05-03
Abstract: PURPOSE:To facilitate setting of the flow resistance and simplify processing of a restrictive passage, which is to communicate two chambers divided by a partition wall, by forming the restrictive passage at the interior surface of the wall of one of the supporting members. CONSTITUTION:No.1 supporting member 1 to be mounted on the frame of a car is formed at a cylindrical basis 12 with its major part given a greater wall thickness, and a partition wall 5 having a movable member 55 interposed between two thin flat plates 51, 52 is fixed to a stepped part 9 provided at this cylindrical basis 12.

Title: Method and device for purifying condensed water
Inventor: ISHIMARU HITOSHI
IPC: G05D7/00
Filed: 1980-07-02
Abstract: PURPOSE: To improve the follow-up property of uniform flow rate control between a plurality of purifying means used in such as a heat power plant by performing the uniform flow rate control of the condensate of the purifying means based on the total condensate flow rate of all the purifying means and the condensate flow rate of the respective purifying means.  
     CONSTITUTION: The total condensate flow rate is detected by a flow rate detector 14 provided on a condensate feeding pipe 3 and the detected value is inputted into a comparator 22. The number of condensate feed pumps in operation is inputted into a preset value selector 25 and also inputted into the comparator 22 via a setting circuit 23 or 24 according to the number to be inputted. The comparator 22 calculates a difference between the 100% flow rate and the total condensate flow rate detected by the detector 14. The resultant is inputted into an average value calculator 40 to obtain an increase in the flow rate for a uniform distribution among the respective condensate purifying means in row 5. The calculation results are inputted into another comparator 26 to be compared with the current flow rate of the respective condensate purifying means 5 provided by another detector 6. The comparator 26 thus provides a control signal based on the comparison to a control valve 7. With this construction, the follow-up property of the uniform flow rate control among the respective purifying means can be much improved.

Filed: 1986-04-17
Abstract: PURPOSE:To automatically adjust the moisture of a casting sand by measuring the moisture of the recovery sand inputted into a sand mill in each short time and calculating the deficient moisture amt. against the target moisture by estimating a holding water weight. CONSTITUTION:A microcomputor 7 stops the work of an infrared moisture gage 6 at the time when the terminal of the recovery sand 2 moved from a belt conveyor 4 reaches the infrared moisture gage 6 and estimates the weight of the recovery sand 2 passed through under the infrared moisture gage 6 and the weight of the water transferred by the belt conveyor 4 until that time. Simultaneously, the belt conveyor 4 is stopped after the time lapse until the recovery sand 2 remaining on the beltconveyor 4 from just under the infrared moisture gage 6 to a sand mill 9 is all dropped on the sand mill 9. The computor 7 then calculates the weight of the water necessary for making the recovery sand 2 the target moisture from the total weight of the water held by the recovery sand 2 and the total weight of the recovery sand 2 and the water of his part is fed to the sand mill 9 by a water feeding device 8.

IPC: G01B11/24
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To provide a method and an equipment for measuring interference in which a shape including a level difference exceeding the wavelength or an absolute distance can be measured accurately at high speed. SOLUTION: A laser light source 60 emits laser a light having a plurality of wavelengths. A light reflected by a surface 4a to be measured interferes with a light reflected by a prototype plane 64 and image pickup tubes 671 -67n detect the fringe pattern image for respective wavelengths individually. A computer 9 selects a set of m-th,..., first wavelengths (m>=2) such that the combined wavelength of a set of two wavelengths selected from among the plurality of wavelengths decreases gradually. Subsequently, the absolute distance between the prototype plane 64 and the surface 4a to be measured is operated roughly and sequentially from the set of m-th wavelength to the set of first wavelength for each set of wavelength based on the phase distribution difference between fringe images corresponding to two wavelengths.  Finally, the absolute distance between the prototype plane 64 and the surface 4a to be measured is operated accurately based on the phase distribution of one of a plurality of wavelengths and the rough absolute distance of the first set of wavelength.

Title: Built-in flash camera
Inventor: ISHIGURO MINORU
IPC: G03B7/16
Filed: 1995-04-14
Abstract: PURPOSE: To control flash light so that the image of an object can be picked up with an optimum exposure amount in accordance with the focal distance of a photographic lens, or image pickup magnification by making a flash switching distance longer as the focal distance at the photographing time is longer by a flash light control part. CONSTITUTION: Luminance in an image pickup visual field is measured by a photometric part 21, a distance up to a main object is measured by a range- finding part, and the focal distance of the photographic lens is detected by a focal distance detecting part. Also, in the flash light control part (CPU 30), such a constant light emission control is executed that the amount of exposure by the flash light is reduced from a standard exposure amount stepwise by taking the measurement results as a parameter. When the distance obtained at switching the reduction amount so as to reduce the amount of exposure by the flash light from the standard exposure amount stepwise based on the distance up to the main object is defined as the flash switching distance, the flash switching distance is made longer as the focal distance at the photographing time is longer in the flash light control part.  Thus, the exposure amount of the main object on an image plane is kept appropriate.
