Title: Manufacture of speaker diaphragm
Inventor: TERAUCHI SHOICHIRO
IPC: H04R7/02
Filed: 1984-10-31
Abstract: PURPOSE:To form a flat flange port by forming a coaxial annular wave-shaped part due to irregularity as the outer circumference at a flange part cutting and removing said part after the occurrence of the winding of the flange part is prevented by ion plating. CONSTITUTION:At an outer circumference of a cone part 4, a plane flange part 5 is formed, at a central side of the cone part 4, a falling part 6 and an inner flange part 7 are formed and further, the coaxial annular wave-shaped part 8 as the cone part is formed at the cone part 4. A diaphragm base material formed like this is increased up to the temperature before and after 500 deg.C, the ion plating of the metal and compound layer is processed and after the metal and compound layer are formed at the surface, the temperature is returned to the room temperature. At such a time, since the ring-shaped wave part 8 is installed at the flange part 5, this goes to a resistance for the occurrence of the winding, the winding will not occur at the flange part 5 and the flat condition is secured. In the diaphragm, which is returned to the room temperature after the ion plating processing is completed, the ring-shaped wave part 8 is cut and removed by a press-cutter.

Title: Heat transfer pipe of down-flowing liquid film type evaporator
Inventor: YAMASHITA KATSUYA
IPC: F28F1/38
Filed: 1982-12-28
Abstract: PURPOSE:To stabilize and to improve the heat transfer efficiency of the heat transfer pipe by a method wherein two heat exchange promotable corrugated sections are arranged parallel to each other in different phases along the axis of the heat transfer pipe. CONSTITUTION:In the case of the down-flowing liquid film type evaporator, a heated fluid flowing out from a fluid distributor flows down as it covers the heat transfer pipe 21 in the form of a film. When the liquid film begins to flow down, the thickness of the film is not uniform but the fluid 1 flowing down in the concave sections 24 of the second heat exchange promotable corrugated section 23 in the upper stage flows down vertically and is divided into a stream 2 flowing over the convex sections 27 of the first heat exchange promotable corrugated section 22 and streams 3 and 4 flowing separately into the concave sections 26 on both sides of the concave sections 27, respectively. Further, a stream 5 of the fluid flowing down over the upper stage convex sections 25 flows into the lower stage concave sections 26 and joins together. Thus, by such tributory flow and the joined flow of the fluid, the thickness of the fluid is made uniform in the circumferential direction, a dry patch disappears in a short time and the heat transfer efficiency of the heat pipe can be maintained high.

Filed: 1982-12-23
Abstract: PURPOSE:To improve the photoelectric conversion efficiency by continuously reducing the density of B of an I type layer from the boundary of P type layer to the surface of an N type layer as prescribed when forming a P-I-N junction with a non-single crystal layer which mainly contains Si added with H or halogen element. CONSTITUTION:A transparent electrode 2 is formed on a glass plate 1, non-single crystal Si layers 3-5 are superposed by a plasma CVD method to form a P- I-N junction, and a transparent electrode 6, and a reflecting electrode 6' are formed. When forming an I type layer 4, B2H4 is added in the amount of 0- 5ppm to an SinH2n+1, the density of B is continuously reduced at the P type layer side from 2X10<15>-2X10<17>cm<-3>, set to 0-1X10<15>cm<-3> at the N type layer side, and the density of B is reduced to 1/5 or less. At this time, depletion layer 55 of P-N junction and a depletion layer 57 of N-I junction are continued in the layer 4, and a drift field having no flat part is formed in an energy band. In other words, the drift field can be effectively formed except the neutralization of N type of the I type layer, thereby improving the photoelectric conversion efficiency.

Abstract: PURPOSE:To decrease the length of a coded code string by storing an input data to a shift register having a serial output terminal and a parallel output terminal and discriminating whether the mode is a compression mode or a non-compression mode from a parallel data outputted from the parallel output terminal of the shift register. CONSTITUTION:A picture data is stored tentatively in the shift register 1. the shift register 1 has the serial output terminal outputting the stored picture data serially and the parallel output terminal outputting the stored picture data in the lump. A mode switching circuit 2 inputs a parallel data from the parallel output terminal and discriminates whether the picture is to be coded by the picture data compression mode stored in the shift register 1 or by the non-compression mode and outputs the result of discrimination to a coding circuit 3. The coding circuit 3 inputs the picture data from the serial output terminal of the shift register 1, encodes the picture data based on the result of discrimination from the mode switching circuit 2 to output the coded code. The more the bit number of the shift register 1 is, the more properly the mode is switched, and 12-16 bits are enough practically.
