Abstract: PURPOSE:To manufacture an element having high performance stably by thermally treating a semiconductor substrate at 500-800 deg.C before or after crystal growth. CONSTITUTION:An N-type active layer 2 is formed onto a semi-insulating substrate 1, and a gate 3 consisting of a refractory metal is shaped. An insulating film 4, such as an silicon oxide film, an silicon nitride film, aluminum nitride, etc. is applied on the whole surface, a photo-resist film is shaped, and windows are bored selectively holding the gate metal in regions in which MOCVD N<+> GaAs layers are formed. An N<+> GaAs layer is shaped through selective MOCVD. In this case, a substrate wafer is set in a reactor, the temperature of the wafer is elevated to 500-800 deg.C, the wafer is annealed in a cap-less manner in an arsine atmosphere for several or 30min, the temperature of the wafer is brought to a desired growth temperature, TMG and a dopant are made to flow, and an N<+> GaAs layer 6 is grown.

Title: Production of vibration damping material
Inventor: FURUHATA YUUSAKU
IPC: B29C69/00
Filed: 1978-12-27
Abstract: PURPOSE: To ensure that a number of products can be producted by onetime molding, to improve productivity, and to reduce material loss by a method wherein a material consisting of an epoxy resin, polyamide resin, and filler is molded into a body thicker than a product, and the body is sliced into products.  
     CONSTITUTION: A composition consisting of an epoxy resin and a polyamide resin, together with a filler such as silver particles and mica particles, is charged into a mixer and mixed under stirring. The mixture is injected into a mold 3 thicker than a product, and hardened to a hardness of 35W95 as measured on a spring-type hardness tester according to JIS K6301 to form a block body 4, which is then taken out of the mold 3 and sliced by slicer 5 to obtain objective flat plate-shaped vibration damping materials of a thickness of 15W20mm, for example. Since surface grinding, deburring, and the like are needless, material loss is reduced. The damping material is used for lining sonar rooms, machine rooms, and the like.

Title: Nonaqueous electrolyte secondary battery
Inventor: EDA NOBUO
IPC: H01M10/05
Filed: 1988-06-29
Abstract: PURPOSE:To increase the charge/discharge efficiency of a negative electrode by adding a polyethylene glycol type noionic surface active agent to an electrolytic solution. CONSTITUTION:A polyethylene glycol type noionic surface active agent is added to an electrolytic solution or a positive electrode 6. Then, as the electrolytic solution is permeated uniformly in the positive electrode 6, the charge/discharge reaction occurs uniformly to make the distribution of the ion transporting line connecting the positive electrode 6 and a negative electrode 4 through the electrolytic solution present uniform two dimensionally, and the precipitation of lithium ion on the negative electrode in charging is also made uniform and smooth. Thus, the contacting surface of the negative electrode 4 with the electrolytic solution is reduced to improve the charge/discharge efficiency, and the battery life is improved.

Title: Data transmitter
Inventor: ABE SHIYUUJI
IPC: H03M5/12
Filed: 1981-10-15
Abstract: PURPOSE:To speed up a titled data transmitter and to make it highly reliable, by phase-modulating transmission data into long and short pulses, transmitting signals corresponding to the pulses with different peaks, and detecting and demodulating the signals at the reception side. CONSTITUTION:Transmission data of H, L is inputted from a terminal 3 at a transmission circuit 1, a modulating circuit 4 outputs pulses of one period corresponding to 1-bit of this data and changes the phase of a pulse signal outputted only at the change to L. This phase-modulated signal becomes a long and short pulse signal on the other hand, and this signal is applied to a driving circuit 5. The circuit 5 converts the signal into a signal with a low and high peak value corresponding to the length of pulses and outputs the signal from a transformer T. A reception circuit 2 detects the presence/absence of a reception data signal inputted from the transformer T at a signal detecting circuit 6, this detecting signal demodulates the reception data into an original data at a demodulation circuit 7 and outputs the data signal from a terminal 8. Since one pulse is enough for one bit, the redundancy is less and high-speed transmission can be attained.

Title: Catalyst for purifying exhaust gas, its production, and method for purifying exhaust gas
Inventor: HIRATA HIROTO
IPC: B01D53/94
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To improve the heat-resisting property of a catalyst, of which carrier contains TiO2, for purifying an exhaust gas, and to further improve its durability. SOLUTION: A NOx occlusion element and a noble metal are carried with a carrier prepared by heat-treating a mixture of ultrafinely granulated TiO2 particles and an porous oxide to be heat stabilized, or with a carrier consisting of fibrous, ultrafinely granulated TiO2 2 and a fibrous porous oxide 1. Even when an endurance test is performed, a reaction of the TiO2 with the NOx occlusion element is suppressed to prevent the grain growth of the TiO2 particle, suppressing the grain growth of the noble metal carried on the TiO2. Thereby the heat-resisting property of the catalyst is improved and a high NOx purifying effect is exhibited even after the endurance.

Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To enable a user to conduct image forming operation even in any device even if identification number is registered in either one image forming device without registering the identification number in every devices intending use. SOLUTION: A CPU 211 of a data terminal control part 200B compares a previously registered identification data with a user identification data inputted by a user, and if the registered identification data agrees with the user identification data, permits the execution of image forming operation, and if does not agree, does not permit. If the registered identification data does not agree with the user identification data, the CPU 211 inquires of other copiers whether they have registered identification data agreeing with the user identification data. In the case that the answer having the registered identification data agreed with the user identification data or the answer permitting image forming operation is received, the CPU 211 changes the decision of no permission to permission.
