Title: Converter for satellite broadcast reception
Inventor: IWAI KEISUKE
IPC: H03D7/00
Filed: 1989-04-11
Abstract: PURPOSE:To use a common board even in the case of different input frequency and local oscillation frequency by constituting the local oscillation circuit with a microstrip line and a high frequency semiconductor amplifier element whose shape is made adjustable so as to vary the oscillating frequency. CONSTITUTION:For example, strip lines 13', 12' are formed to be an optimum pattern in which local oscillating frequency is 10.57kHz. Thus, in the case of European application, the pattern is used without modification. In the case of domestic applications, the strip line 13, and a separation line 23 and the strip line 12' and a separation line 24 are jumpered respectively by adjustment jumpers 25, 26. The local frequency of the domestic applications is slightly lower than that of the European applications. Thus, in the case of domestic applications, the strip lines 13', 12' are prolonged in the optimum pattern of the oscillated frequency, then the board is used for the domestic converter board. Thus, the boards for domestic and European applications are used in common in this way.

Title: Fire extinguishing liquid and fire extinguisher used therefor
Inventor: ISHIKAWA KAZUO
IPC: A62D1/06
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To provide an effect with which the efficacy of fire extinguishment is sufficiently expected and to allow immediate use without the need for preparing water, etc., by bringing potasium hydroxide and sodium carbonate into reaction in water with metal silicon as a catalyst, thereby forming a fire extinguishing liquid. SOLUTION: This fire extinguishing liquid is formed by bringing the sodium hydroxide and the potasium carbonate into reaction in the water with the metal silicon as the catalyst. This fire extinguishing liquid is not a two-pack type and extinguishes a fire by the incombustible liquid which covers the fire when the formed reaction liquid is discharged. The liquid is novel as the fire extinguishing liquid as well and exhibits a remarkable effect as initial fire extinguishment. In case oil burns, an acid-alkali fire extinguisher has no effect but this fire extinguishing liquid acts effectively regardless of the kinds of combustibles.

Title: Electron shower device
Inventor: EGUCHI MASANAO
IPC: H01J37/317
Filed: 1987-04-14
Abstract: PURPOSE:To solve the problem of charge-up phenomenon of a semiconductor substrate with an electron shower by providing a selecting means for secondary electrons which leads only secondary electrons out of secondary electrons and reflected electrons generated at a secondary electron generator into a desired trajectory. CONSTITUTION:Thermoelectrons are generated by energizing a first filament and they are pulled out and accelerated by a pulling out electrode 2. These accelerated electrons generate secondary electrons and some are simply reflected by impinging upon a target 3. When these generated electrons and reflected electrons pass through a static lens 6, according to the voltage which is applied to the lens 6, the electrons which reach an area on the semiconductor substrate 4 to be irradiated by an ion beam are limited to those of a specific energy level. A charge-up phenomenon generated on the surface of the semiconductor substrate 4 can be dissolved by an electron shower produced by low energy electrons which reach the surface of the semiconductor substrate 4.

Filed: 1985-04-30
Abstract: PURPOSE:To obtain a good polished surface with less polishing scratches by providing a large and deep groove and a small and shallow groove on a polishing surface and carrying out a polishing operation using a polishing liquid in which abrasive grains are mixed and also a polishing liquid in which abrasive grains are not mixed. CONSTITUTION:A workpiece 8 mounted on a holder 7 is placed on a polishing surface table 1 on the polishing surface of which a large and deep groove 5 and small and shallow grooves 6 are provided, and a polishing liquid in which abrasive grains 11 are mixed is fed while rotating the workpiece 8, to carry out a polishing operation. After that, when a polishing liquid in which the abrasive grains are not mixed, is fed continuously, the polishing liquid containing the abrasive grains 11 is discharged out form the grooves 6 to the groove 5 due to the centrifugal force caused by the rotation of the polishing surface table, and the action of the workpiece 8 which is rotated while being in contact with the polishing surface. Thus, the abrasive grains are prevented from being caught in on the polishing surface and, as the polishing liquid without abrasive grains is continuously fed, abrasive grains 12 which have been kept laid in due to polishing pressure, enable the polishing liquid to serve as a lubricating agent on carrying out polishing operation. Thereby, a good polished surface with less polishing scratches can be obtained.
