Title: Speaker diaphragm
Inventor: MARUNO YOSHIAKI
IPC: H04R7/08
Filed: 1982-03-08
Abstract: PURPOSE:To improve the characteristics of a speaker diaphragm, by folding zigzag a rectangular plate-like body to contract the surface of one side and expand the other side to obtain a circular skelton part, adhering a surface material to both sides of the skelton, and varying the folding pitch toward the cirfumference of the skelton. CONSTITUTION:A rectangular plate-like body 1 is folded zigzag. Thus the surface 1A of one side of the plate 1 is contracted to form an inner circumference surface, and the surface 1B of the other side is expanded to form a circular body. At the same time, the folding pitch is varied toward the circumference of the circular body. A surface material 2 is adhered to both sides of a circular skelton member 1. The rough pitch part of the member 1 has small rigidity, and the node gets close to the center with the primary resonance frequency. On the contrary, the rigidity is shown by a curve (a) for the dense pitch part. As a result, the flat characteristics of reproduction are obtained at a high frequency band for a speaker diaphragm.

Abstract: PURPOSE:To separate easily and surely an intermediate tone picture and a binary picture image by deciding that data fall into a binary character region when the result obtained by subtracting the read data of an input picture from its binary coded data is a prescribed value or smaller, and when the result is a prescribed value or greater, the data fall into an intermediate tone picture region. CONSTITUTION:A picture data read by a reading device 3 is stored in a memory 4. A maximum value and a minimum value of the picture data in the memory 4 are detected by a maximum value and minimum value detecting circuit 5 and inputted to a fixed binary-coding circuit 6. An intermediate value between the maximum value and the minimum value is set in the circuit 6 as a threshold value, and the picture data is binary-coded and stored in a memory 7. The contents of the memory 7 are subtracted from the contents of the memory 4 at a subtraction circuit 8, a discriminating circuit 9 discriminates whether or not the subtracted value is nearly 0, and inputs the result to a dot pattern generating circuit 10. The circuit 10 discriminates that the input picture is a data for the binary character image region 2 when the result of subtraction is nearly 0 and discriminates it as a data in the intermediate tone picture region 1 when the result of subtraction is other than nearly 0, thereby using a dot matrix pattern depending on the case and prints the picture on paper.

Subsequently, the retaining plate 2 is vertically erected, the melt 5 and the source substrate 4 are brought to come in contact with each other, and the melt 5 is saturated. Then, the retaining plate is horizontally positioned, the substrate 3 and the melt 5 are contacted, and an epitaxial growth is performed. Lastly, the retaining plate 2 and the melt 5 are separated and cooled. As the specific heat of the sapphire plate is large, the temperature of the substrate 3 is lowered later than the other part, and the melt vapor is not condensed on the substrate 3.

Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To shorten the exchange time of a developer, without making a load on the developer heavy by making the rotational speeds of carrying members variable. SOLUTION: At the time of executing normal printing, the developer in a developing device 4 is carried, while being stirred in the axial direction of a developing roll 12, by the carrying members 11. The revolving speeds of the carrying members 11 at this time are fixed by the property of stirring the developer and the load thereon, to be constant. The developer pushed out by the carrying members 11 is carried to the developing roll 12 by a water tribune type paddle 13, uniformly leveled by a regulating member 14 and then, moved to a developing part, to develop a photoreceptor with toner. The developer after the development with the toner is completed is returned to the carrying members 11 by the paddle 13 again and carried-stirred by the carrying members 11.  Then, the developer is discharged only by the reverse operations of the carrying members 11, bit at this time, only in the initial stage of the discharge, where the load is heaviest, rotation at a normal revolving speed is attained. When the developer is discharged by some degree and the load is light, the rotation is made fast.

Title: Waste gas purifier
Inventor: MACHIDA MINORU
IPC: F01N13/02
Filed: 1994-03-08
Abstract: PURPOSE:To sufficiently remove the harmful components in exhaust gas such as CO, hydrocarbons and NOx when an engine has not been warmed up immediately after its start or when the engine has been warmed up. CONSTITUTION:The exhaust gas discharged from an engine main body 1 is purified by a first exhaust gas purifier 16 and further by a second exhaust gas purifier 17. Since the first purifier 16 has a small volume and the heat capacity of a catalyst carrier is low, the exhaust gas is purified to a high degree even when the main body 1 has not been warmed up. As the second purifier 17 has a large volume and the geometrical surface area of the carrier is large, the harmful components which have not been removed in the first purifier 16 are removed in the second purifier when the main body 1 has been warmed up.
