Title: Method for diagnosing coating film deterioration with laser beam
Inventor: TANAKA MICHIO
IPC: G01N21/3563
Filed: 1987-10-31
Abstract: PURPOSE:To diagnose the degree of deterioration of the coating film of a building, etc., quantitatively without any destruction by irradiating the coating film with a laser beam having specific wavelength, measuring its reflected light, and diagnosing the degree of deterioration of the coating film from the detected value. CONSTITUTION:When a laser driving power source 2 is turned on, a variable wavelength laser device 3 emits a variable-wavelength laser beam, which is projected on the coating film 1 at a specific position through a convergence optical system 4. The projected light is reflected by the surface of the coating film 1 at an angle theta2 of reflection matching with its angle theta1 of incidence, and the light is passed through the convergence optical system 5; and a detector 6 detects the intensity of the laser beam and the intensity of the reflected light with the wavelength is detected by an X-Y recorder 8 through an amplifier 7. Then if the coating film 1 deteriorates, resin constituting the resin film 1 reacts on ultraviolet rays, etc., and is decomposed to change in its molecular structure, thereby obtaining the light intensity corresponding to the degree of its deterioration. The degree of the deterioration is therefore found from the reflected light intensity and incident light intensity.

Title: Film smoothing mechanism of camera
Inventor: OTSUKA YASUNOBU
IPC: G03B17/28
Filed: 1992-10-15
Abstract: PURPOSE:To reduce the power consumption due to the drive using a simple circuit configuration by furnishing a delay means which delays a signal to be given to a solenoid coil. CONSTITUTION:When a mirror-up signal is fed, a delay circuit 1 delays the signal for a certain time as not required to drive a solenoid 5. A solenoid attracting time control circuit 2 receives the output of the delay circuit 1 and makes counting for a certain time. A solenoid hold control circuit 3 receives the outputs of the delay circuit 1 and solenoid attracting time control circuit 2 and gives an appropriate signal to a solenoid drive circuit 4. The circuit 4 receives the signal and performs film attracting and holding motions with the solenoid 5. The holding motion is made with a lesser current to the current at the time of attraction. Thus the film is held in attraction to a pressure plate, and the flatness of the film is secured.

Title: Image expanding processing method
Inventor: NODA HIDEO
IPC: G06T11/20
Filed: 1999-09-29
Abstract: PROBLEM TO BE SOLVED: To prevent the damage of a line segment form without omitting dots in pseudo double accuracy DDA processing for forming dots on zigzag arrangement. SOLUTION: This method is based on DDA processing for forming dots along with vector data by inputting the vector data, storing the gradient corresponding values of vector data in respect to respective coordinate values in the first axis direction of an orthogonal coordinate system specified by these vector data, changing one of coordinate values in the second axis direction of the orthogonal coordinate system at a time point, when the stored quantity exceeds a prescribed value, and subtracting the prescribed value from the stored quantity. DDA processing is executed on the orthogonal coordinate system where accuracy in the first and second axis directions of the orthogonal coordinate system is made double respectively.  When the stored quantity exceeds the prescribed value, one of coordinate values is changed in the second axis direction as long as the position of a dot before changing one of coordinate values in the second axis direction is not located on the zigzag arrangement to be an even number when coordinate values in the first and second axis directions are added.

Title: Single operation detector and detecting method for synchronous generator
Inventor: ISHIGURO MASAHARU
IPC: H02P9/14
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To detect single operation of a synchronous generator for supplying a generated power flow back to an AC commercial power supply surely regardless of fluctuation of load of consumer. SOLUTION: A frequency detector 31 detects the frequency of an output voltage signal SOUT in disturbed state to output a frequency detection signal SFRQ and a disturbance amplitude detector 32 extracts a signal having same frequency component as a disturbance signal contained in the frequency detection signal SFRQ to detect the amplitude of the same frequency component signal. Since a comparator 34 judges whether a synchronous generator is in single operation state or not based on the amplitude of the same frequency component signal detected by the disturbance amplitude detector 32 and a predetermined reference amplitude, single operation can be detected surely regardless of fluctuation in the frequency or voltage of a commercial power system.

Title: Production of hydrogen occluding alloy
Inventor: MORIWAKI YOSHIO
IPC: C22F1/18
Filed: 1984-12-26
Abstract: PURPOSE:To eliminate the need for a pulverizing stage to avert the generation of a pulverization loss and to permit the packing of a uniform alloy in an adequate amt. into a vessel by forming a hydrogen occluding alloy into an ingot having the shape conforming to the internal shape of the vessel for contg. said alloy. CONSTITUTION:The hydrogen occluding alloy is melted and is then cast by a casting mold so that the ingot of the shape conforming to the inside shape of the vessel contg. the specific hydrogen occluding alloy is obtd. The surface of the ingot is preferably partly removed by a mechanical or chemical means. The adjustment of the amt. of the ingot to be packed into the vessel is thus made easy and the packing rate is made uniform in all places in the vessel. The alloy packed into the vessel is easily and automatically pulverized by the hydrogenation and there is no need for preliminary pulverization. The shape of the ingot to be cast may be a simple shape such as circular columnar, cylindrical, polygonal columnar or spherical shape or the divided bodies, a flat plate shape, etc. The above-mentioned method is effective for the hydrogen occluding alloy which is a Ti-Mn alloy permitting relatively easy initial hydrogenation and where the alloy phase is an MgZn2 type Laves phase (hexagonal crystal).
