IPC: H01L21/223
Filed: 1979-09-14
Abstract: PURPOSE:To diffuse the zinc in high density distribution at a surface and low density at an inside of a substrate by a method wherein ZnAs2 or ZnP2 and III-V group compound semiconductor wafers are vacuum sealed in the same container and wafers are preserve at a high temperature. CONSTITUTION:To diffuse the Zn on the III-V group compound semiconductor at low density, there are a method using GaZn alloy, a method that an SiO2 mask is coated on the GaAs substrate, and Zn is diffused through the mask or others, but there are problems for the weighing of the diffusion source or a complexness of the process, further the surface density will be reduced when the inside densisty of wafer is lowered, it is very difficult to form an excellent ohmic connection. For this reason the ZnAs2 2 as the diffusion source is vacuum sealed in a quartz pipe 1 with the GaAs substrate 3, and make the temperature of the diffusion source 2 and the substrate 3 as T2, T1, when T1 is preserved at 700-900 deg.C, T2 at 600-700 deg.C, the Zn density can be diffused in the high distribution at the surface of substrate, in the low distribution at the inside. Such a method is simple and very advantageous for the manufacturing of LED or others.

IPC: G01N27/12
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To attain a stable operation for a long period by forming a membrane made of a polymer material into a porous structure capable of holding electrolyte salt after it absorbs moisture and becomes an aqueous solution, and suppressing the electrolyte salt from flowing out of the functional membrane. SOLUTION: A hydrophilic polymer material, e.g. polyvinyl alcohol, is formed into a porous membrane 301. A membrane (holding membrane) 303 of a hydrophobic polymer material, e.g. polyvinyl acetate, is formed on the inner walls of multiple holes 302 formed in the membrane 301. The membrane 303 can be considered as a mixed body of the hydrophilic polymer material and the hydrophobic polymer material. The strength of the membrane 301 is increased by the existance of the membrane 303. When the membrane 301 is impregnated with a lithium chloride aqueous solution, lithium chloride 304 is held in the holes 302. The lithium chloride aqueous solution is held in the porous holes of the functional membrane impregnated with the lithium chloride aqueous solution.

Title: Multiplexer
Inventor: SATO YOSHIO
IPC: H04J3/00
Filed: 1987-05-15
Abstract: PURPOSE:To increase the utilization efficiency of a high-speed digital line and to transmit even a data signal modulated by a data modem by selecting and connecting a CODEC for both a speech signal and a data signal when the data signal is detected from an input signal. CONSTITUTION:When data signal detection parts 12-14 detect no data signal, a switch 15 selects and connects CODECs 16 and 17 dedicated to the speech signal preferentially. Further, when the data signal detection parts 12-14 detects a data signal, the switch 15 selects and connects CODECs 18 and 19 dedicated to the speech data. The CODECs 16 and 17 dedicated to the speech signal and CODECs 18 and 19 dedicated to the speech data convert analog signals into digital data, but the speech signal dedicated CODECs 16 and 17 encode the speech signal into a low bit rate signal with high efficiency. Consequently, the efficient utilization of a high-speed digital line using the high-efficiency CODECs and the transmission of a data signal are both performed.

IPC: C08G59/14
Filed: 1980-08-28
Abstract: PURPOSE: To obtain a flexible epoxy resin with improved flexibility, by modifying a liquid butadiene/acrylonitrile copolymer rubber with an epoxy resin by use of a triphenylphosphine catalyst.  
     CONSTITUTION: One (1) eq. liquid butadiene/acrylonitrile copolymer rubber having, on the average, at least two carboxyl groups per molecule on both molecular ends is modified with at least 2.3eq. epoxy resin having, on the average, at least two epoxy groups per molecule in the absence of a solvent by use of a triphenylphosphine catalyst. The triphenylphosphine catalyst is used pereferably in an amount of 0.05W0.2pt.wt. per 100pts.wt. epoxy resin. The modification reaction is carried out preferably at a temperature of 70W160°C. Temperatures outside the above range are not preferred because the reaction is extremely slow at a temperature below 70°C even in the presence of a catalyst whereas the epoxy resin undergoes thermal polymerization at a temperature of above 160°C, and the flexibility is lowered.

Title: Piston ring
Inventor: NICHIMA KAZUNORI
IPC: C23C14/14
Filed: 1995-04-24
Abstract: PURPOSE: To prevent a piston ring from seizing and reduce oil consumption by making the diameter of the second layer of the piston ring smaller than that of the outermost layer of the piston ring and making the hardness of the upper and lower end sections of both sides of the piston ring than that of the center section. CONSTITUTION: The ring body 12 of a piston ring 11 and the external peripheral surface, on which an arc-like barrel face of R1 in radius is formed, are provided with ordinary chromium plated layers 13. The radius of the external peripheral surface of this chromium plated layer 13 is R2 , and R2 >R1 . The center section of the external peripheral surface of the ring body 12 is made of the base material of the ring body 12 with high hardness, and at the upper and lower end sections on both sides, small layer with hardness of 3 to 30μare formed.  When the piston moves while swinging toward the internal peripheral surface of a cylinder, the upper and lower end sections slidably contact with the internal peripheral surface of the cylinder, and normally, the center section slidably contacts with the internal peripheral surface, as a result, the whole of the external peripheral surface of the ring body is uniformly worn. This makes it possible to keep a barrel form. By this constitution, even if this piston is used for a high speed and high power engine, the characteristics of the external peripheral surface of a ring with a barrel form can always be exhibited.
