Title: Equipment for removing smoke, etc
Inventor: OONO GENJI
IPC: B03C3/41
Filed: 1979-09-10
Abstract: PURPOSE: To provide a compact structure and to prevent the reduction of smoke removing efficiency during operation by a method wherein a corona discharge electrode is installed so that its discharge projection end directs toward the inlet side of gas stream in a cylindrical smoke passage having internal electrode plates.  
     CONSTITUTION: When a high voltage is applied across discharge electrode 7 and facing electrode 1, corona discharge from the projected end 12 of the discharge electrode 7 produces corona ions, which rush along arrow mark 8 onto the facing electrode 1 in shower form. The projected end 12 which is installed toward the inlet side of passage 2 produces near its end a negative pressure area. Gas stream flowing into the negative pressure area goes along the side surface of the discharge electrode 7 where no corona charge exists, flowing from the outlet side of the passage 2, and causes one-side directional flow toward the projected end 12 as shown by the arrow 17. Contaminated air is introduced from the open end 10 of the inlet side to the passage 2 and is pushed by corona wind toward the facing electrode 1 as shown by the arrow 9, and moves in the passage toward the outlet side.

Title: Controlling system of multivariable function generating device
Inventor: HIBINO KATSUHIKO
IPC: G06F7/64
Filed: 1981-07-23
Abstract: PURPOSE:To eliminate any error from the operation results by obtaining correct operation results from the initial value in terms of operations performed under the cooperation of a digital differential analyzer (DDA) and a multivariable function generating device (DDFG). CONSTITUTION:Control signal outputs LS2-LS4 and AND gates G1-G3 of a control memory MP are individually inserted, and, when a switch S is set to the off condition, each variable latching circuit LX, LY, and LZ do not make any holding operations because the control signal outputs LS2-LS4 and the AND gates G1-G3 are also set to the off condition and no gradient value is sent from a gradient value memory MG. Therefore, when a timing pulse generator TPG is operated under the condition where the switch S is set to the off condition before starting the whole arithmetic operation, an interval definition point memory MNB or a interval definition point controlling circuit DC, a variable memory MV, the control memory MP, the variable latching circuit LX, etc., of a multivariable function generating device (DDFG) operate, and a variable outputted from a register YR at a digital differential analyser (DDA) side is held by the variable latching circuit LX. Moreover, an approximate partition point in an interval definition point memory MN coincides with the outputted variable by the operations of the interval definition point memory MNB or the interval definition point controlling circuit DC.

Title: Repeat copying machine
Inventor: ISHII YASUAKI
IPC: G03B27/14
Filed: 1980-08-26
Abstract: PURPOSE:To separate only photosensitive paper from a printing cylinder by bringing a shifting roller into contact with the printing roller selectively. CONSTITUTION:An original 8 and photosensitive paper 11 are carried in hermetic contact with a printing cylinder 1 by a belt 4. As a rotary arm 13 rotates on a fulcrum 13a, a sliding roller 14 touches the leading edge of the photosensitive paper. At this time, the shifting roller is stopped by releasing the clutch of a driving system or driven at a slower speed than a printing cylinder surface, so the leading edge of the photosensitive paper shifts from the original. Then, when the rotations of the shifting  roller are returned to the original rotations, the photosensitive paper is ejected out through the operation of a pick-off table 5. After prescribed number of sheets of photosensitive paper are printed, any photosensitive paper is supplied any more, so the shifting roller 14 comes into contact with the original to eject the original.

Title: Manufacture of racket frame
Inventor: FURANKU UIRIAMU POTSUPURUUERU
IPC: A63B49/10
Filed: 1980-08-25
Abstract: A method of making a games racket frame by injecting thermoplastics material into the space (13) between a fusible core (14) and a mould at a temperature above the melting point of the core. The core (14) is shaped to have locating lugs (15) to abut against the internal walls of the mould and hold the core in the desired position. The moulding is allowed to set and the core then melted out by raising the temperature sufficiently for that purpose but insufficiently to deform the moulding. The lugs (15) enable the core (14) to be located in the desired position in the mould and to resist displacement from that location during injection. The holes formed in the wall of the frame because of the abutment of lugs and mould wall can conveniently be utilized as stringing holes.
