Title: Manufacture of semiconductor device
Inventor: IWAMATSU SEIICHI
IPC: H01L21/3205
Filed: 1988-03-01
Abstract: PURPOSE:To cope with the increase in current level on a junction part and to decrease the junction resistance by a method wherein a trench is formed in a conductor substrate below a contact hole by a dry etching process and then a semiconductor film is epitaxially deposited to be buried in the trench including both sides thereof. CONSTITUTION:An insulating film 2 is formed on the surface of a semiconductor substrate 1 to make a contact hole in the film 2, a trench (groove) is formed from the surface of the semiconductor substrate 1 on the bottom of the contact hole by dry etching process and then a single crystal semiconductor film is formed burying the trench part and the contact hole part 3 by selective epitaxial deposition so as to make the surface of the buried epitaxial film flush with the surface of the insulating film 2. Through these procedures, the step disconnection in the contact part 3 of later Al wiring, etc., can be prevented from occurring enabling the junction area of the trench epitaxial contact part 3 to be expanded so that the junction part may be supplied with large current and the junction resistance may be lowered.

Title: Multistage collector type electron beam tube
Inventor: KIMURA SHIYUNICHI
IPC: H01J23/027
Filed: 1979-04-19
Abstract: PURPOSE:To remove heat generated in collector by providing plural collectors close to the inside of a cylindrical ceramic with holes for collector leads and fixed its one end on the output side end of a high frequency circuit portion. CONSTITUTION:The cylindrical ceramic 11 whose tiered inside is provided with the first to third collectors 7, 8 and 9 and whose other side end is vacuum-sealed by the ceramic plate 12 by means of soldering, with the holes 13 for taking out collector leads, is fixed by soldering to the output side end of the high frequency circuit 4. Thus, heat generated in the first to third collectors 7-9 is transmitted to the heat radiator 17 through the cylindrical ceramic 11, and therefore the heat transmittance path toward the heat radiator 17 leading to a heat-releasing portion (the holding plate 6) is reduced to one regardless of the divided number of the collector, permitting the structure of the collector portion to be simplified. The thermal resistance between each collector and the heat radiator 17 is determined by the material and dimension of ceramic used.

Title: Telephone system
Inventor: HASE YASUHIKO
IPC: H04M1/274
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To automatically descriminate domestic/international calls and to attain the dial calling via a proper telephone line connection company by providing a comparison means, which compares a code stored in a storage means with a country code included in an input telephone number and a means which changes the input telephone number according to the comparison result of the comparison means. SOLUTION: A control part 1 compares a country code included in the input telephone number with a country code stored in a country code storage area 53 of a call number memory 5. If it is decided that the country number matches with the country code, the part 1 decides the input telephone number as a domestic telephone number and carries on its processing to replace the head symbol '+' of the input telephone number and the following country number with a domestic call number stored in a domestic call number storage area 51 of the memory 5. Thus, it is possible to automatically discriminate domestic/ international calls, simply by examining a telephone number including the country code and then to connect the dial calling via a proper telephone line connection company.

Title: Optical system for original reader
Inventor: TOKUMITSU JIYUN
IPC: G02B27/18
Filed: 1980-04-14
Abstract: PURPOSE:To prevent the change in refractive index for the infiltration of moisture from end parts by keeping the distance between the effective lens parts of a lens array consisting of plastics and the end face of a lens array block at more than half the thickness of the effective lens parts. CONSTITUTION:Effective plastic lens parts 91, 92 are formed to a lens array block 8 of a copying machine or the like formed of plastics such as polymethyl methacrylate (PMMA) by leaving a distance (l) from the end face of the block. If the distance (l) from the end face of the block up to the effective lens parts is kept at >=1/2 the thickness of the effective lens parts, it results in that, when the moisture infiltering from the end face of the block has arrived at the effective lens parts, the moisture having already infiltered from both faces of the lens has already spread over the entire part of the lens. Hence, the distribution in the refractive index in the direction perpendicular to the optical axis harmful for imaging performance does not occur.
