Title: Facsimile equipment
Inventor: HAMADA HIROSHI
IPC: H04N1/387
Filed: 1989-07-10
Abstract: PURPOSE:To suppress deterioration in a picture and distortion by applying recording based on resolution at the recording with respect to plural standards whose resolution differs. CONSTITUTION:When a transmission request comes from other terminal equipment, conventional negotiation is executed. In this case, the information of picture density handled at the sender terminal equipment, that is, the information of resolution is received and the resolution is discriminated in the receiver facsimile equipment. When the resolution is discriminated to be 400dpiX400dpi of the G4 standard, since the frequency is set to be 1/2 frequency division of fo, a CPU 3 sends a select signal d to select a signal a to the selector 104. When the synchronizing clock set simultaneously is set to an LBP 9, the reception of the picture data is sequentially started and print-out of the set synchronizing clock is implemented by the LBP 9 simultaneously. Thus, the data reception and printout are repeated and when the transmission is finished from the sender, this processing uses the normal procedure to interrupt the line and to terminate the processing.

Title: Solar cell
Inventor: HAYASHI TSUKASA
IPC: H01L31/04
Filed: 1992-07-03
Abstract: PURPOSE:To generate electric power in a high efficiency by forming a structure in which a quantum wire base material having many quantum fine lines is interposed between an n-type semiconductor and a p-type semiconductor. CONSTITUTION:The solar cell has a structure in which a quantum wire base material layer 1 having many quantum wires 11 is interposed between a p-type semiconductor layer 2 and an n-type semiconductor layer 3. An electrode wiring of a transparent conductive film is provided on the semiconductor 2, and a metal electrode wiring 5 is provided on the layer 3. The lines 11 of the layer 1 are so formed that their diameters are small on the side of a transparent electrode 4 where solar light is incident and gradually increased toward the side of the metal electrode 5. Light incident on the layer 1 is absorbed in such a manner that light having a short wavelength is first absorbed by a region having a wide quantization level and light having a long wavelength is absorbed by a region having a narrow quantization level. Thus, since the light is absorbed in a wide wavelength range, the efficiency of power generation by the solar light is improved. When the wires are formed of a diameter distribution in which light can be absorbed in a wide wavelength range, a high efficiency power generation is performed.

Title: Synchronizer ring
Inventor: YAMAMOTO YOSHIKAZU
IPC: F16D23/12
Filed: 1986-07-25
Abstract: PURPOSE:To reduce a deterioration with the passage of time in the friction characteristic of the synchronizer ring in the caption by forming a sliding part with a wet friction member and arranging friction members with a large porosity and a small porosity alternately in the axial center direction of a ring-shaped base. CONSTITUTION:A sliding part 30 is formed with a wet friction member on a base inner periphery 3, and the wet friction member is formed by arranging friction members with a large porosity and a small porosity alternately in the axial center direction of a ring-shaped base 1. Therefore, a friction surface is cooled by a circulating flow of a lubricating oil and seizure with a mating gear cone is prevented in the large porosity area. And a mechanical strength is kept and good performance in friction and abrasion characteristics can be shown in the small porosity area. Therefore, a friction coefficient can be maintained within a range of some 0.08-0.13 and a malfunction such as the unsmooth shifting or the faulty synchronizing can be prevented. Also, a deterioration with the passage of time in the friction characteristic can be reduced with a stable contact condition and frictional force, as a sliding part 3 is made in flat and a contact area can be kept constant even in case of its abrasion.

Title: Ptfe composition containing anisotropic melt forming polymer
Inventor: DAARITSUKU SHIDONII BEIRII
IPC: C08L27/18
Filed: 1981-11-06
Abstract: Compositions containing a polymer of PTFE and a polymer capable of exhibiting an anisotropic melt characterised in that the compositions contain between 0.05 and 99.5% of PTFE and 0.5 to 99.95% by weight of the polymer capable of forming an anisotropic melt. The presence of a minor amount of the anisotropic melt-forming polymer, that is, from 0.5 to 50% by weight of the composition enables the processability of PTFE to be improved, even to the extent of providing an injection mouldable PTFE composition. Compositions containing 20 to 50% by weight of PTFE confer benefits on anisotropic melt-forming polymers, such as lubricity and greater versatility in fabrication operations. Concentration of 0.05 to 5.0% by weight of PTFE are particularly suitable for modifying the viscosity characteristics of the low melt viscosity anisotropic melt-forming polymers so that such anisotropic melt polymers are less subject to problems such as flashing and jetting during moulding.
