IPC: H04N5/232
Filed: 1988-02-20
Abstract: PURPOSE:To rapidly and smoothly control a focussing by using the deviation of a focussing position in the focal point depth of the respective areas of a light receiving face based on the inclination of the thickness of a protecting cover body and discriminating the direction of the deviation of the focal point by comparing the levels of the high frequency components of the light receiving signals of the respective areas. CONSTITUTION:An image pickup light passing through a lens 1 is received by an image pickup element 2 through the cover body 3 and the light receiving signals of the respective picture elements of the light receiving face are outputted to a processing circuit 7 from the image pickup element 2. The high frequency component of the light receiving signal of the fields of the respective areas A-C of the image pickup element 1 is separated and extracted by a processing part 4, added and averaged for every area and converted to the data of an evaluation value little in an error for comparing a level. A CPU 5 compares in level the high frequency components of the areas A-C to decide a front pin and a back pin and discriminate the direction of the deviation of the focal point. Thereby, the lens 1 is drawn to the focussing position according to the rapid and smooth focussing control.

Title: Constant pressure type boiling cooler
Inventor: OKADA TEIGO
IPC: F25D9/00
Filed: 1978-04-05
Abstract: PURPOSE: To secure the boiling-cooling at the constant pressure at all times by always setting the  pressure within the cooler to the value slightly larger or smaller than the atmospheric pressure and  then shifting the refrigerant boiling point to the cooling target temperature.   
     CONSTITUTION: The pressure inside the container is the sum of the atmospheric pressure and  weight 10 when the heating value of heat generator 9 is O, which is identical to the saturation  vapor pressure of refrigerant solution 8a and at the target boiling temperature. With generation of  heat, refrigerant vapor 8c and solution 8a reach reservoir 6a via tube 5a. In this case vapor 8c is  liquefied 8b, and companding part 7 expands to secure balance. The temperature increment of  solution 8a becomes O by the circulation of boiling and condensation to be identical to the saturation vapor pressure a the target boiling point. With more intensive heat generation, solution 8a  reduces and the condensation area of condenser 3 increases, and solution 8a is kept at the target  boiling point. With decrement of the heating value, the container's inner pressure lowers down  and solution 8b shifts to cooling container, and part 7 contracts to keep automatically the temperature of 8a at the target boiling point and then to be kept at the saturation vapor pressure then.  Thus, the steady and satisfactory boiling cooling performance can be obtained with selection of  weight 10.

Abstract: PURPOSE:To always obtain a picture having a proper density by making it difficult for a density reference setting part to be influenced by dirt. CONSTITUTION:The outer peripheral surface of a roll 21 as a back platen is colored with a white paint or a white film is wound to form a reference white area 21a as the density reference setting part. This roll 21 is driven at a low speed through a reduction mechanism by a rotation driving transmission system.

Whereupon, the sensor 8 reaches the position 8' approaching a reflecting member 12. Therefore, the sensor 8 can obtain sufficient detection accuracy. Further, when the sensor moves to the position of the thermal head 3'', the sensor 8 does not move from the position 8'. When the sheet cassette is taken out, the thermal head 3 is allowed to move to the original position.
