IPC: B65G23/00
Filed: 1987-04-13
Abstract: PURPOSE:To prevent discontinuous motion of a casting conveyor by fixing a small gear and a cam between axis of a driving sprocket and a tip thereby partially accelerating or decelerating a conveyor sprocket through operation of the cam. CONSTITUTION:A driving sprocket 4 is slided while rotating on a shaft 11 by means of a driving geared motor 1, a small sprocket 2 and a roller chain 3. Upon rotation of the driving sprocket 4, a small gear 6 engages with a large gear 5 and rolls so as to rotate a cam 7.

Title: Medium housing device
Inventor: FUKUSHIMA TOSHIO
IPC: B65H29/40
Filed: 1985-04-26
Abstract: PURPOSE:To stop a rear end of a medium, making it jump up and turnover, as well as to stock sheets of paper in good order, by making a revolving speed of an impeller provided with plural blades bending each tip end outward slower than that of the recording medium being discharged. CONSTITUTION:When the paper 4 discharged out of a recording device enters a blade 30, the paper 4 gets into the blade 30 because rotation of a rotary shaft 28 is slower than a feed rate of a discharge roller 9, and it hits the root of the blade 30 and held thereat. When further it rotates, the paper 4 collides with the stopper 32 set up in a lower part of the rotary shaft 28, whereby a rear end 31 of the blade 30 uplifts a rear end of the paper 4, having it curved, and the paper 4 is turned over in utilizing its own elasticity. With rotation after that, the paper 4 separates from the inside of the blade and drops down, thus sheets of paper are housed in consecutive order.

Title: Line filter
Inventor: TANIGUCHI AKIRA
IPC: H03H7/09
Filed: 1989-04-12
Abstract: PURPOSE:To reduce noise energy by connecting a couple of rectifier elements back to back so that a connecting point reaches a high level, connecting other couple of rectifier elements back to back whose connecting point reaches a low level, and connecting a capacitor between connecting points of the rectifier element pairs. CONSTITUTION:Diodes D1, D2 of a line filter A are connected at the anodes and diode D3, D4 are connected at the cathodes. When normal mode noise invades on lines l1, l2, the voltage across a capacitor C1 is fluctuated and a current flows to the capacitor. Thus, the noise is bypassed by the capacitor C1 to attenuate noise. In a line filter B, diodes D5,D6 are connected by the cathodes and diodes D7, D8 are connected at the anodes. When common mode noise invades on lines l1, l2, a level of a connecting point (c) or (d) is fluctuated the level of the capacitors C2, C3 is fluctuated, a current flows to them to bypass noise to ground thereby attenuating the noise.

Inventor: TOMABECHI MAKOTO
IPC: B02B7/00
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To provide an extraneous matter removing device for rice husking and milling equipment capable of saving an equipment cost while capable of removing relatively small extraneous matter. SOLUTION: The extraneous matter removing device 20 for removing the extraneous matter, such as saw dust and coins, intruded into unpolished rice is disposed in the position right under the discharge port of a husking device 10 in an unpolished rice supplying path 21 for communicating the husking device 10 with a stone removing device 30. The extraneous matter removing device 20 is composed of two stages of upper and lower receiving members formed with many unpolished rice passage hole parts. The unpolished rice is more liable to be bridging form than unhulled rice and, therefore, even if the unpolished rice passage hole parts of the receiving members are formed to a small hold diameter, the unpolished rice can pass the hole parts without any hindrance and, therefore, the removal of even the small extraneous matter is made possible.

Abstract: PURPOSE:To ensure the stabilized communication by actuating a pseudo random num ber generator with the clock of a master station to spread and modulate signals for wire transmission of them and extracting the clock out of the received signal at a slave station to actuate the pseudo random number generator for spread and demodulation of signals. CONSTITUTION:A master station 12 modulates 34 a carrier wave 19 with the clock of a clock generator 33 to send it to a line 11 and also actuates a pseudo random number generator 14 for production of pseudo random number trains t1, t2...

A common line signal 17 is spreaded and modulated 16 by the random number train t1 and the wave 19 is transmitted to the line 11 after balanced modulation 18. The common line signal received by the station 13a is demodulated 22 and spreaded and demodulated 21 by the random number train t2. The random number trains t3, t4... are allocated for information propert to each slave station and then used for spread/modulation and spread/demodulation like the common line signal. Thus reference clock can be surely reproduced.

Filed: 1988-04-13
Abstract: PURPOSE:To increase the number of characters to be simultaneously entered and displayed on one picture by displaying a character entry frame on a position close adjacent to a character display position for a recognized result. CONSTITUTION:The title system is provided with a means 7 for storing the size of a character entry frame Y to be displayed on a screen, means 5, 6 for storing the display position of a recognized result Z and the size of displayed characters and a means 8 for determining the position of the succeeding character entry frame Y based upon parameters stored in the means 5-7. A hand- written character is entered in the frame Y, a recognized result is displayed on the frame Z, and after erasing a holograph, the frame Y is moved to the succeeding input position only by the size of the frame Z. Since the character entry area and the recognized result display area can be adjacently displayed, the movement of a visual point can be reduced and only one character entry frame Y necessary as an entry area may be prepared, so that a trouble compressing the number of display characters by the character entry area can be suppressed at its minimum and the sufficient number of display characters can be assured.
