Filed: 1985-02-06
Abstract: PURPOSE:To be able to generate a large amount of heat with a small device by installing a catalyst layer in such a manner that fuel is supplied from one side of the catalyst layer and diffused into it and gas containing molecular oxygen such as air especially is forced to flow out from the other side of the catalyst layer. CONSTITUTION:It is desirable that a catalyst layer takes the shape of a cylinder with one end closed. Fuel is diffused from an inner side of the catalyst layer and air etc. is forced to flow around its outer circumference by a fan.

Filed: 1979-02-22
Abstract: PURPOSE: To ensure the combined use of the 2-band selection circuit and the 3-band display circuit by converting the 2-band channel selection voltage into the 3-band channel selection voltage.  
     CONSTITUTION: Both 2-band band information UI 8  and 2-band channel selection information BTI 8  are given to channel selection control signal unit 8 which converts the 2-band information into the 3-band information.

Abstract: PROBLEM TO BE SOLVED: To provide a method for synthesizing a single crystal diamond covering a large area by specifying a face direction of the generated diamond nuclei on a single crystal preform plate and synthesizing while charging an electric current in the surface of the preform in a gas phase synthetic method. SOLUTION: This method for synthesizing a diamond is to perform a diamond synthesis on a silicon preform plate 10 while charging an electric current between electrodes 12, 14, so as to grow the [100] direction of the nuclei 18 of the synthesized diamond along the [100] direction in the surface of the silicon preform plate, to form the nuclei 18 having the same surface direction with the silicone preform plate 10. Since the electric current is to help the directional growth of the nuclei 18 in the initial period of the growth, there is no need to charge the current after the formation of nuclei 18.  Even by using [110], [111] silicon preform plate, it is possible to make the directional growth of the nuclei by charging the electric current, and even by charging the current in the direction of [110], [111], [112], it is possible to form the diamond nuclei in the same surface direction of the base preform plate. As the base preform plate, even by using a β-SiC, it is possible to make a hetero epitaxial growth of the diamond, and further, even a base preform plate of an alloy consisting of Ni, Cu as main components can be used.

Filed: 1980-02-22
Abstract: PURPOSE:To remove undesired As diffusion by a method wherein after As ions are injected, the insulating film surface is etched and subsequently a heat treatment is applied thereto. CONSTITUTION:Into a P type Si substrate 1, B ions are injected 2 by using an Si3N4 mask 8 and wet-oxidized to form a field oxide film 3. Then, the mask 8 is removed, and a gate oxide film 4 and a polycrystalline Si gate electrode 5 are formed. After As ions have been injected thereinto, this is dipped in an HF solution to selectively etch the surface layer of the ion-injected SiO2. The polycrystalline Si layer 5 and the Si substrate 1 are not etched. Then, this is treated in N2 at approximately 1,000 deg.C to recover the crystal lattice, and N layers 6 and 7 are provided. By said constitution, because As in the field oxide film has been removed, there is no possibility that As invades the channel cut layer 2 in the high-temperature treatment, resulting in lowering in concentration or inversion. Accordingly, reliability of the device improves.

Title: Real time communication system
Inventor: SHIMAKAWA HIROMITSU
IPC: H04Q3/00
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To decide channel establishment utilizing effectively a communication channel by giving a channel use admission to a client node when a new channel is set within a channel use period on request in the case of channel setup and informing the end of communication of a channel. SOLUTION: When a new channel 6 is set within a channel use period on request in the case of channel setup, a channel use admission is given to a client node. Then end of communication is informed to a channel 6 whose communication is finished. Thus, it is avoided that the channel 6 having been once set up remains for a long time and setup of a new channel 6 is difficult as the time using the communication system gets longer. Furthermore, since an exclusive channel 5 adopting the CBR communication system is employed for the channel 6 from a transmission client node 2 to a reception client node 2, data for communication at channel set up and release are communicated in real time without being disturbed by other communication.
