Abstract: PROBLEM TO BE SOLVED: To reduce the number of parts and to attain miniaturization by means of processing the reception of a plurality of frequency bands in a common circuit by up-converting a low frequency signals to match with a high frequency signal. SOLUTION: When receiving the signal of two frequency band, that is, an L-Band and a VHF band, the signal of the 174-245 MHz VHF band separated by a duplexer 101 is synthesized with the local oscillation signal of 126.992 MHz, which is generated by a PLL circuit 131, by means of a mixer 141 and only a 1443.992-1514.992 MHz convert signal passes through a BPF 122 and is up-converted. Then it is selected by a change-over switch 102, passes through an LNA 112 and the BPF 123, is combined with the local oscillation signal of 1230.992-1301.992 MHz, which is generated by the PLL circuit 132, by means of the second mixer 142 and converted into an intermediate frequency signal of 213 MHz.  Then a disturbance wave is removed by a band-pass filter 124, combined with the local oscillation signal of 215 MHz from the PLL circuit 133, converted into a signal of 2 MHz and outputted to a demodulating circuit.

Title: Ultrasonic distance measuring instrument
Inventor: KATAYAMA SUSUMU
IPC: G01S13/10
Filed: 1989-08-28
Abstract: PURPOSE:To measure up to a long distance and to shorten the measurement time by making the numbers of ultrasonic wave transmitters and receivers which are driven at the same time smaller for a shorter distance and larger for a longer distance. CONSTITUTION:This distance measuring instrument drives all ultrasonic wave vibrators 3 at the same time within a range of longer than a preset distance and when measurement data on shorter than a set distance is obtained, the number of ultrasonic wave vibrators 3 which are driven according to the distance is decreased with the distance to decrease output sound pressure and reception sensitivity as the distance is short, thereby measuring the distance in the best state according to the distance. Namely, an unnecessary area due to a side lobe is hardly formed and even when a short distance is measured, an unnecessary reflected signal is hardly generated, so the measurement time can be shortened.

Title: Liquid-cooled type stationary induction apparatus
Inventor: ISHIKAWA KIYOYUKI
IPC: H01F27/10
Filed: 1990-08-22
Abstract: PURPOSE:To prevent the local temperature rise of an core by flowing down a liquid cooling medium uniformly along the side of the iron core by providing a guide for forcibly deflecting the medium, flowing toward the peripheral wall on a tank side, vertically downward thereby feeding the liquid cooling medium downward uniformly along the side face of the care. CONSTITUTION:A liquid cooling medium 6 dropping down on a packing 3 flows to a space G side along a channel 3a and then deflected forcibly by a cooling medium guide 9 to flow downward into a space between the guide 9 and the side peripheral face of a core 2. Since the clearance between the side peripheral face of the core 2 and the guide 9 is narrow, the space between them is filled with the cooling medium 6 and in the vicinity of a bent portion of the guide 9, a turbulent flow comes about. And at a time when the cooling medium reaches the lower end of the guide 9, it turns to a laminar flow and flows down. Since the guide 9 is provided with a vertical guide 9a, a lateral divergent flow of the cooling medium 6 is suppressed. Accordingly, even if the quantity of the liquid cooling medium 6 is not increased, it flows in a condition where the space between the guide 9 and the side peripheral face of the core 2 is full of the cooling medium. And while running through the space between them, the cooling medium flows down along the side peripheral face of the core 2 in a form of laminar flow, whereby the side peripheral face of the core 2 can evenly be cooled down.

Title: Method and device for inputting word of foreign origin word in japanese word processor
Inventor: HIRAMATSU SUMIO
IPC: G06F17/22
Filed: 1985-10-05
Abstract: PURPOSE:To reduce the number of times of keying by inputting the long sound symbol of KATAKANA (square form of Japanese syllabary) with the vowel of the KATAKANA character just before the long sound symbol and making it unnecessary to switch a device to the KATAKANA input state when the words of foreign origin are inputted. CONSTITUTION:When the word of foreign origin which is normally expressed with KATAKANA is inputted, the long sound symbol of KATAKANA is expressed with the vowel of the KATAKANA character just before the long sound symbol and this vowel is inputted. For example, 'user' is read to input 'yuuzaa'. Since the long sound symbol is not inputted, it is unnecessary to operate a shift key to set the KATAKANA input state for the purpose of inputting the long sound symbol, and the number of times of keying is reduced. Even if the long sound symbol is not included in register objects of reading of a user register dictionary 22 where readings of idioms are registered, the words of foreign origin including the long sound symbol are registered in the user register dictionary 22 without remodeling hardware at all.
