Title: Solar heat collector
Inventor: TAKAGI TADASHI
IPC: F24J2/48
Filed: 1979-04-25
Abstract: PURPOSE: To utilize visible rays of the solar energy in order to heat water effectively by making up the outside part of the circumference of the collector with a transparent material and the inside part with an opaque material.  
     CONSTITUTION: The circumferential wall 1 that forms the hollow part 4 of the solar heat collector is composed of double layers which consist of the outside clear layer 2 and the inside opaque layer 3 that is fairly thinner than the clear layer 2. In this way, the visible rays f 1  that occupies most of solar energy passes through the clear layer 2, reaches the surface 3a of the opaque layer 3, and is absorbed here and converted into heat. The heat conducts in the opaque layer 3, reaches the inner surface 3b and heats water. In this case, since the thickness of the opaque layer 3 is thinner than the clear layer, the thermal conductivity is enhanced. On the other hand, most of infrared rays f 2  is absorbed by the surface 2a of the transparent layer 2, part of which penetrates through the inteior of the layer 2, its thermal energy transfers in the transparent and opaque layers, reaches the inner surface 3b and conducts to the water.

Title: Diazo photosensitive paper
IPC: D21H27/00
Filed: 1992-03-11
Abstract: PURPOSE:To prevent the degradation in the density of an image part and to suppress the yellowing of a texture part by having a photosensitive layer contg. a diazonium compd. and a naphthoic acid coupler component and containing cyclodextrin in this photosensitive layer or precoating layer. CONSTITUTION:The photosensitive layer contg. the diazonium compd. and the naphthoic acid coupler component is formed and the cyclodextrin is contained in this photosensitive layer or the precoating layer. The cyclodextrin has a cyclic structure and forms a clathrate compd. by taking various kinds of org. compds. into the molecular cavities. Therefore, the cyclodextrin prevents photooxidation by including the coupled diazonium compd. and the unreacted couplers therein. Particularly the the hydroxyl groups of the substituents of the naphthoic acid coupler component are made into a quinone structure by the effect of light or oxygen, etc., and the yellowing is prevented by the clathrate effect of the cyclodextrin. Any compds. which couple under the conditions of an azo coupling component are usable as the diazonium compd. to be used in this case.

Abstract: PURPOSE:To decrease the discharge quantity in response to the rise of the rotating speed at the fixed rotating speed or above by providing a damper means functioning to decrease the throttle opening of a variable throttle in sequence from the preset value in response to the rise after the rise to the fixed rotating speed. CONSTITUTION:After the rotating speed of a driving shaft 11 rises to the fixed rotating speed, the throttle opening of a variable throttle valve B is decreased in sequence from the preset value in response to the rise of the rotating speed mainly by the cooperative action of a cam means E and a damper means F. When the throttle opening of the variable throttle valve B is decreased, the front/rear pressure difference of the variable throttle valve B is increased, and a pressure compensating valve C moves a valve body 31 to the balanced position between the action force based on the front/rear pressure difference of the variable throttle valve B with the decreased throttle opening and the elastic force of a spring 33 to guide a pressure fluid to the action chamber 23 of an operation piston 21. The operation piston 21 is moved to displace a swash plate 14 in the discharge quantity decreasing direction, and the discharge quantity of a variable displacement type hydraulic pump A for one rotation is decreased so that the front/rear pressure difference of the variable throttle valve B with the decreased throttle opening is made constant.

Abstract: PURPOSE:To make it possible to provide an interconnection method for a semiconductor integrated circuit characterized by high probability of layout of a three-layer interconnection gate array in which interconnection capacity is less and therefore operation speed is high, by using a third layer interconnection for interconnection among functional cells in this three-layer interconnection gate array at an interconnection part, which is in parallel with the column of input/output terminals, and using a second layer interconnection at a interconnection, part, which is vertical to the column of the input/output terminals. CONSTITUTION:In interconnection among functional cells 1, a third layer interconnection 4 is wired for an interconnection part, which is in parallel to the column of input/output terminals 2. A second layer interconnection 3 is provided for an interconnection part, which is vertical to the column of the input/output terminals. Namely, in a two-layer gate array, a rectangular dedicated interconnection region 12, which is long in parallel to the column of the input/output terminals, is provided among the column of the basic cells. The interconnection part, which is vertical to the column of the input/output terminals is made much shorter than the interconnection part, which is in parallel to said column in this three-layer interconnection gate array. Thus the total interconnection length of the wiring part, which is in parallel to the column of the input/output terminals, is longer than the total interconnection length of the interconnection part, which is vertical to the column of the input/output terminal.

Abstract: PURPOSE:To shorten leading-in time and to prevent mislocking by sampling a burst signal to input one or several-wave components to a circulation type memory and circulating them continuously in one horizontal period to form a burst continuous wave and synchronizing the burst continuous wave with the burst signal in every horizontal period correctly. CONSTITUTION:Since a changeover switch 17 is connected to the A side in the pulse period of a signal SSW, the digital data of a burst signal SSC from an A/D converter 16 is supplied as input data to a memory 18 during this period and is written there successively. Since the changeover switch 17 is connected to the B side when the pulse period of the signal SSW elapses, the circulating state where the output data of the memory 18 is supplied as input data to the memory 18 is set after the elapse of the pulse period of the signal SSW till the next pulse period of the signal SSW. Thus, a burst continuous wave SSC is obtained as the output data from the memory 18 and is converted to an analog data by a D/A converter 19 and is supplied to a PLL circuit 20.

Abstract: PURPOSE:To measure a difference between a surface to be measured and a logical specular surface with high precision by fitting a sensor to a boat-shaped frame for the measurement of a specular surface, and measuring relative position relation with the center of rotation of said frame, namely, logical center. CONSTITUTION:A measuring device is rotated on a reference surface SP and height Z of a sensor S1 from the reference surface of a jig 10 at each angle of rotation is mesured, so that when a center CR of rotation is inclined, the height Z is represented by a sine curve. From heights Z1-Z4 at the maximum point B and minimum point A of the curve and inter-jig sizes X1 and X3, a CR slanting angle alpha is found. Then, distances Xm1 and Xm3 between the jig and center CR are found to find the center of a pin 9. Next, a normal-directional distance between the center of the pin and a logical specular surface 1 is calculated to find a clearance between the sensor and the logical specular surface. This clearance is compared with a measured clearance between the measured specular surface and sensor to measure the precision of the specular surface.
