Title: Method and device for detecting focus
Inventor: MUSHIYA TOORU
IPC: G02B7/28
Filed: 1980-09-30
Abstract: PURPOSE:To reduce the size of the optical system and, at the same time, to always detect an accurate focusing condition, by setting the surface of reflection of the detection prism so that it becomes larger than the critical angle to the incident ray when the ray is in focus. CONSTITUTION:Lights from a light source 21 is made into a prallel luminous flux at a collimater lens 22, and the flux is focused on a desk 26 through a polarized prism 23, a 1/4 wavelength plate 24 and an objective lens 25. The light reflected by the desk 26 is reflected by the polarized prism 23. The reflected luminous flux is made incident to a detection prism 27 and the luminous flux reflected by the reflection surface 27 is photodetected by a light detector 28. This surface of reflection 27a is set so that it becomes larger than the critical angle to at least a part of the incident ray when the ray is in focus. Since, when this arrangement is made, only a detection prism having a constant inclined angle is required, the optical adjustment can be made easily. Moreover, focusing error signals of the light detector 28 become 0 in a range with the focusing location as the center and the range becomes an blind sector, and thus, accurate focusing conditions can always be detected.

Filed: 1993-05-13
Abstract: PURPOSE:To correct an image with white blur, black floating or the like by detecting the distributed state of display picture elements in a dark luminance part and a bright luminance part on a display screen and adjusting brightness and contrast in accordance with the distributed state. CONSTITUTION:An input picture obtained from a matrix part 2 is converted into a digital signal by an A/D conversion part 10. A black area control part 11 detects a dark luminance part in a display picture based upon a luminance signal in the input video signal. A white area control part 12 detects a bright part in the display picture. When the contrast of the display screen is not formed and both of the distribution value of display picture elements in the black area and that in the white area are less than reference values, the control parts 11, 12 respectively output control signals for reducing brightness and increasing contrast. The brightness and contrast signals are corrected by a control part 13 so that the brightness of the display screen is reduced and the contrast is increased.

Abstract: PURPOSE: To improve productivity by pulling both ends of a metal wire in the longitudinal direction by holding both ends and energizing between both ends of the metal wire and heating/softening the metal wire and certainly straightening the metal wire so as to prevent generation of a defective product. CONSTITUTION: Both ends of a metal wire W are respectively held by holding means 11, 12, the metal wire W is pulled by a prescribed tension T while the holding means 12 is moved by a drive means 15, an electric current of a prescribed value is caused to flow into the metal wire W by a power unit 18. Thus, by energizing the metal wire W while maintaining a tension state, the strain generated in the inside of the metal wire W is gradually eliminated so as to be straightened. After a prescribed time elapses, energizing is stopped, at the same time the tension state is released and the metal wire W is left as it is until the temp. of metal wire W is lowered, and straightening of bends of the metal wire W is completed.

Title: Method and apparatus for detecting frequency and power system stabilization system
Inventor: TAKAHASHI TORU
IPC: H02H3/46
Filed: 1994-06-17
Abstract: PURPOSE:To detect the frequency with higher accuracy than linear approximation during a half cycle detection period by calculating the actual detection time of half cycle using a sampling phase time difference operated according to an inverse trigonometric function and then determining the frequency based on the reciprocal. CONSTITUTION:An AC amount Vi is sampled at a constant period DELTAT(e.g. 30 deg. of electric angle) and inputted while counting Ki. A current Vi is multiplied by a previous Vi-1 and the sign is determined. If the sign is negative, a zero point of AC is present and the time difference DELTAti between the zero point and current sampling point is calculated and stored. The time Ts of detecting section (between zero points) is then calculated based on the previous phase time difference DELTAti(i) to be stored, the number of sampling times KXDELTAT, and the current DELTAti. The detection frequency is determined as one half of the reciprocal of the time Ts and then the K is cleared thus waiting next input. Since the detecting section can be extended to a multiple of half cycle while sustaining the half cycle detection period, the accuracy can be enhanced.

Title: Heat exchanger
Inventor: NAKAYAMA KOICHI
IPC: F28F1/30
Filed: 1993-06-07
Abstract: PURPOSE:To prevent water from scattering into a room by a method wherein a mesh fin is attached at the leeward end of a corrugated fin so that condensate water gathering on the corrugated fin is absorbed by the mesh fin. CONSTITUTION:Refrigerant evaporates in a flat pipe 21 to cool air passing through a corrugated fin 22, and moisture condenses on the corrugated fin 22. The condensate water is washed away backward from the corrugated fin 22 by air flow and absorbed by a mesh fin 23 attached at the leeward end of the corrugated fin 22. Then, the condensate water flows along the mesh fin 23 and is discharged outside without scattering into a room. Therefore, the draft resistance can be reduced.
