Title: Camera
Inventor: HOSHINO YASUSHI
IPC: G01C3/00
Filed: 1985-04-30
Abstract: PURPOSE:To obtain accurate distance measuring data by taking in the range finding voltage obtained by reflected light as the range finding data after a prescribed time elapses from a point of time when a light emitting element emits light. CONSTITUTION:After a capacitor C1 charged with a CdS initialized, a brightness processing part A of a subject measures a time until the voltage coincides with the reference voltage with a CPU 1 to detect the object brightness. On the other hand, a rang finding processing part B measures a time until the voltage of a capacitor C2 charged with the constant current coincides with the range finding voltage in proportion to the distance to the subject with the CPU 1 to perform a range finding process. At this time, after the prescribed time (about 90ms) elapses from a point of time when the light emitting element for finding a range emits light, a transistor Q2 is made off from on by the CPU 1. Then, the charging of the constant current to the capacitor C2 is started and the range finding voltage is converted into the time and taken in to obtain the accurate distance measuring data.

Abstract: PURPOSE: To provide an assembly of hose and reel, which is designed to be capable of omitting a rotary seal that has been required in conventional arrangements for connecting the hose with an oil supply pipe communicated to a pump, whereby it is enabled to lower the manufacturing costs and at the same time to solve the problem of leakage.  
     CONSTITUTION: A first reel 2 having a relatively large diameter and a second reel 3 having a relatively small diameter are both fixedly mounted on a single turning shaft 1, and a connecting tube 11 is extened between these two reels 2, 3 for connecting the inner end (starting end) 8a of a first hose 8 wigh the inner end (starting end) 10a of a second hose 10. When turning shaft 1 is turned for reeling out hose 8 at the top of which an oil supplying nozzle is to be connected, hose 8 is reeled out of reel 2 whereas hose 10 is turned only at its inner end 10a since its outer end 10b is fixed. Therefore, rotation of reel 3 is absorbed while increasing the diameter of turns of hose 10. Here, spring member 15 functions to extend the turns of hose uniformly in radial direction of the reel.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing coke which keeps the height of coke constant during push-out and thereby prevent the damage of oven wall by reducing the pressure on the push-out side during the push out of coke. SOLUTION: This method for producing coke is characterized in that the expansion pressure of the blended coal to be charged into a coke oven is determined; the compression coefficient of the blended coal is determined based on that the difference between the compression coefficient of the blended coal and the standard compression coefficient in the coke oven is proportional to the expansion pressure of the blended coal; the charging height of the coal to be charged is determined based on the compression coefficient of the blended coal; and thereby the height of coke cake during push-out is held at constant.  The expansion pressure of blended coal can be determined based on the weighted mean of the expansion pressures of individual branded coals constituting a coal blend, blending ratio of non-slightly-caking coal and the total expansion coefficient of coal other than the non-slightly-caking coal.

Title: Heat transfer fins
Inventor: HATADA TOSHIO
IPC: F28F1/32
Filed: 1986-04-25
Abstract: PURPOSE:To improve the heat transfer performance of the heat transfer fins making the projected area in the ventilation direction of a louver larger than that of both side parts in the vicinity of the central part of the louver, in louver-shaped fins. CONSTITUTION:The section in the ventilation direction of a louver is set to a conical shape, for example, and the angle of a conical part in the vicinity of a louver central part is made larger, and the angle at both end parts 3 and 3' of the louver is made small. Both end parts 3 and 3' are used as louvers 6-10 having a small cone angle thetaand the central part 4 of the louver is used as louvers 11-15 having a large cone angle theta'. Since a ventilation resistance becomes large in the vicinity of the central part 4 of the louver, the air flow speed becomes slow, whereas since the ventilation resistance is small at both sides of each of louvers 3 and 3' having a small sectional cone angle, the air flow speed is increased. Since the temperature difference between the air flow and fins is small in the vicinity of the central part 4 of the louver, lowering of the air flow has no large effect on the heat transfer performance. Since the temperature difference between the air flow and fins is large, the increase in the air flow improves largely the heat performance. As a result, the total heat transfer performance of fins is improved.
