Title: Correction device for character string
Inventor: KAWADA SHIGERU
IPC: G06F17/24
Filed: 1993-05-27
Abstract: PURPOSE:To correct a character string with less keys. CONSTITUTION:When characters becoming bases are arranged in a matrix shape, the character string to be corrected is displayed in a display area 84. Cursor keys 6L, 6U, 6R and 6D are operated, and a first cursor is moved to the display place of the character to be corrected. When a decision key 6K is depressed, the characters for one line in the matrix are displayed in a display area 83. When the cursor keys 6L and 6R are operated, a second cursor is moved to the direction of the line one character by one in the display area 83. When the cursor keys 6U and 6D are operated, at least the string where the second cursor is displayed is scrawled in the direction of a column in the display of the characters at the display area 83. When a correction key 6S is operated, the character in the place where the second cursor is displayed is displayed in the place where the first cursor is displayed in the character string to be corrected, and the character string of the display result is written into the memory as the character string of a correction result.

IPC: E03F5/14
Filed: 1977-12-09
Abstract: PURPOSE: To provide an automatic dust remover which can smoothly operate with less trouble and corrosions by providing detachably a comb-like damper with convexly curved portion at the side facing with water stream between the front screen top and the rear screen.  
     CONSTITUTION: Dusts and refuse flowing into a water channel are collected at a front screen 1. When this automatic dust remover is stopped, a damper 14 is pushed forwards with a curved portion 17 disposed between the front screen 1 and a plate 2 so that the dusts may not pass through the screen 1. When the dust remover is operated, a drive motor 7 is operated to scrape up the dusts and refuse collected by the screen 1 via a rake 5. The rake 5 thus elevated makes contact with the curved portion 17 of the plate-like rod 15 of the damper 14. When the damper 14 is rocked to move to the left and further raised, it is gradually moved to the right upon energization of a spring means 18 to the original portion without trouble.

Title: Resetting system for automatic equalizer
Inventor: TAKAOKA KAZUHIKO
IPC: H04L25/03
Filed: 1985-07-09
Abstract: PURPOSE:To prevent divergence of an equalizer by saving and storing a coefficient of an automatic equalizer at the end of operation establishment and setting the coefficient of the automatic equalizer saved and stored in advance when the divergence of the automatic equalizer is detected in the reception of message data. CONSTITUTION:A modulated input signal X is demodulated by a demodulation circuit 1 base don a carrier from a carrier generating circuit 8 and equalized by the automatic equalizer comprising an automatic equalizing section 3, a decision section 4 and an error calculating section 5 via a LPF 2. The coefficient of the automatic equalizer when the operation establishment is finished by receiving a training check signal at a phase B is transferred and stored in a RAM 7 storing the coefficient of equalizer via an equalizer coefficient control circuit 6 by using a coefficient preserving command C. When the divergence is detected by a divergence detection circuit 9 while the message data is received at a phase C, the circuit 6 uses a divergence detection signal E to transfer the equalizer coefficient stored in the RAM 7 to a RAM of the equalizing section 3. Thus, the divergence of the equalizer is prevented.

Filed: 1980-10-27
Abstract: PURPOSE:To remove residual charge in a short time by varying the resistance value of resistance for residual charge removal by forming the resistance by a high- resistance insulating liquid and by mixing an electrolytic liquid with the insulating liquid. CONSTITUTION:During charging to a high DC voltage, a main resistance 8 and an auxiliary resistance 9 are filled with high-natural-resistance insulating liquids respectively to operate as insulators. After the charging, a pump 12 is actuated immediately to open a valve 13, mixing and dispersing an electrolytic liquid in a tank 14 with and into the insulating liquids. The main resistance 7 and auxiliary resistance 9 decreses in value with an increase in the mixture quantity of the electrolytic liquid, so the mixture quantity is increased gradually and smoothly through the operation of the valve 13 to remove the residual charge of a cable line 1 without causing sudden variations of a voltage which damage the cable line. The time required for varying the resistances is much shorter than the time for natural discharge, and the time required for a DC dielectric-strength test is shortened greatly.
