Title: Comb line filter
Inventor: YOKOYAMA TAKEO
IPC: H04N9/78
Filed: 1983-05-23
Abstract: PURPOSE:To separate a chrominance signal and a luminance signal in excellent way, by using an anti-resonate coil provided at an input terminal for processing the signals separated in low and high frequencies. CONSTITUTION:An NTSC color television signal is inputted to a glass-made delay line 22 including the anti-resonate coil 26. This circuit has no reactance component at frequencies below the operating band of the glass delay line 22 and no phase shift between a signal voltage applied across a voltage dividing load 14 and an input voltage is caused. The glass delay line and the anti-resonate coil 26 are in parallel resonance within the operating band. The glass delay line 22 is operated in the best efficiency in this case. The characteristics of the comb line filter are formed by synthesizing a signal passing through the glass delay line 22 and the signal applied to the voltage dividing load 24. Since this comb line filter has a broad band, the chrominance signal and the luminance signal are separated in excellent way.

Title: Kana/kanji conversion method
Inventor: KATO TSUNEAKI
IPC: G06F17/22
Filed: 1991-04-22
Abstract: PURPOSE:To simplify an operation to decide the desired one out of the converted KANA (Japanese syllabary)/KANJI (Chinese character) conversion candidates. CONSTITUTION:A fact whether an input character string is identical with a special character string to be decided or not (S2). If not, the KANA/KANJI conversion is carried out and the KANJI string candidates are obtained (S3). Then it is checked whether the character string candidtes are accumulated in a conversion candidate processing part or not (S4). If not, the obtained conversion candidates are accumulated in the conversion candidate processing part (S5). If the candidates are accumulated in the step S4, the input character string is decided as a selected input (S7). If the accumulated conversion candidates show five different types of 'KOSEI' in KANJI to the 'KOSEI' in KANA and if the conversion candidate of the inputted selected input is 'KO' (KANJI) to 'OOYAKE' (KANA), a conversion candidate including the KANJI equal to 'KO' is extracted out of those KANJI conversion candidates and a 'KOSEI' (KANJI) is displayed as the selection result. When an input character string is decided in the step S2, the accumulated candidates of the conversion candidate processing part are cleared away.

Filed: 1985-04-26
Abstract: PURPOSE:To control a limit voltage with high accuracy by amplifying the temperature fluctuation of a terminal voltage of a temperature-sensing element and applying temperature control of a limit voltage to suppress the temperature change in the limit of a multiple rate of an APD. CONSTITUTION:An output signal level of a photodetector 1 photoelectrically converting an incident optical signal is kept always constant by controlling a bias voltage of the photodetector 1 so as to control the multiple rate. The photodetecting circuit equipped with the function above is provided with a limiter circuit 8 limiting the bias voltage controlling the multiple rate of the photodetector 1 lower by a prescribed value when the level of the input optical signal is lowered to limit the abnormal rise of the multiple rate of the photodetector 1. Thus, the limit voltage of the limiter circuit 8 is limited in response to the temperature change of the multiple rate of the photodetector 1 by using a temperature-sensing element 11. For example, a differential amplifier 12 amplifies the change in the terminal voltage of the element 11 due to temperature fluctuation and the temperature fluctuation of the limit value of the multiple rate of an APD 1 is suppressed by applying temperature control of the limit voltage of the limiter circuit 8.

Abstract: PURPOSE:To nicely and uniformly apply a highly viscous coating even under water by a method wherein the coating is fed from a coating feeding pipe to a coating feeding body with a larger crosssection than the pipe to decrease the speed and the coating is distributed into a plurality of ejection holes for the coating and the coating is smoothed by means of a brush. CONSTITUTION:When a coating feeding cock 3 is opened by driving a coating compressor fixed on the base end part of a coating feeding pipe 1, a coating is fed into a coating feeding body 5. As the crosssectional area of the coating feeding body 5 is larger than the crosssectional area of the coating feeding pipe 1, the coating decreases its speed and is guided to a coating guiding member 6 and it is ejected toward a coating face 11a of an article 11 to be coated from a coating ejecting hole 12 at a proper speed. Then, an operator handles the base end part of the coating feeding body 5 and moves this in the coating direction and the coating is smoothed by means of a brush planted on a lid member 8 to coat it on the coating face 11a. In this case, as the coating feeding body is freely rotatably supported by means of a swivel joint 4, the coating feeding body 5 can be rotated to an easily workable position.
