Title: Rotary atomizing head for coating
Inventor: KATO MASAHIRO
IPC: B05B3/10
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To obtain a rotary atomizing head by fitting a mounting body, which is formed to a nearly double cylindrical type, is blinded between an inside cylinder and an outside cylinder and is formed with many coating material through-holes in the outer peripheral part of its base, to the inner peripheral surface of an atomizing head body flared with the inner peripheral surface to a taper shape from the top end toward the bottom end, fitting the front end of the output shaft of an air motor to the inside cylinder and disposing a coating material supply pipe so as to face the eccentric position in the opening of the front surface of the atomizing head body so as to prevent the interference thereof with the output shaft. SOLUTION: A flange 9, which constitutes a slit 8 of nearly an inverted L shape in the section regulating the outflow of the coating material between the outlet surface of the coating material through-holes 6 and the inner peripheral surface of the atomizing head body 1, is fixed to the rear surface of the mounting body 2. As a result, even if a large amt. of the coating material flows down from the coating material through-holes 6 right below the coating material supply pipe 7 larger than from the other coating material through-holes 6, the coating material does not flow down immediately and after the coating material once accumulates in the slit 8, the coating material flows down. The coating material is then stirred by centrifual force while the coating material accumulates in the slit 8.  This coating material flows down uniformly over the entire periphery of the inner peripheral surface of the atomizing head body.

Title: Power amplifier circuit
Inventor: SHIBUYA TOSHIFUMI
IPC: H03F1/08
Filed: 1984-02-01
Abstract: PURPOSE:To decrease the output sound pressure level against the change in a speaker impedance by inserting a resistor in series with a speaker so as to detect a voltage generated across the resistor and injecting the voltage to a negative feedback circuit. CONSTITUTION:When the input impedance of the speaker 8 is changed because of heat or the like, the voltage produced across the resistor 6 is changed. The feedback amount is changed by injecting said voltage to a feedback circuit (comprising resistors 4, 3) via a resistor 5. Thus, when the internal impedance of the speaker 8 is decreased, a current i0 is increased and the voltage across the resistor 6 is increased. Then the potential of an inverting input of a power amplifier circuit 2 is increased, its output voltage v0 is decreased and the current i0 is decreased, resulting that the output change is decreased.

Title: Manufacture of flexible printed board
Inventor: NUMATA SHUNICHI
IPC: H05K1/03
Filed: 1992-01-31
Abstract: PURPOSE:To contrive to give an adhesive force to a flexible printed board without generating curling, twist, warpage and the like in the board even if a heat history is applied to the board by a method wherein a polyamic acid copolymer consisting of a polyamic acid, which is shown by a specified formula, or a blended varnish is directly applied and dried on a conductor foil and is imidated by heating to obtain a laminated material. CONSTITUTION:A polyimide obtainable by heating a polyamic acid, which is shown by the formula, is upright and has a very small linear expansion coefficient. However, in the case the polyimide is formed integrally with a metal foil, such as a copper foil and an aluminium foil, and is used as flexible printed board, there are many cases in which the polyimide's side is too small in linear expansion coefficient and it is necessary that a conventional polyimide, which is flexible and has a comparatively large linear expansion coefficient, is copolymerized or is made to synthesize separately and thereafter, the polyimide is blended in the state of a precursor. The mechanical fragility of the board is eliminated by the introduction of a flexible skeleton and the introduction has an effect on the improvement of the adhesion of the board.

Title: Optical disk device
Inventor: SHIO YUTAKA
IPC: G11B7/095
Filed: 1993-02-03
Abstract: PURPOSE:To eliminate the generation of servo turbulence by holding a difference signal when a sum signal varies rapidly and selecting the normalized difference signal at the time of little fluctuation. CONSTITUTION:Dividing means 9, 10 normalize a focusing difference signal and a tracking difference signal by dividing the focusing difference signal and the tracking difference signal by the sum signal. When the sum signal fluctuates rapidly, the focusing difference signal and the tracking difference signal normalized by the dividing means 9, 10 are held by a holding means i.e., a sample-and- hold means 25, 28 just before or just after the fluctuation. At the time of little fluctuation of the sum signal, the focusing difference signal normalized by the dividing means 9, 10 is selected and the reserved focusing difference signal and the tracking difference signal are selected for a prescribed time interval at the time of the rapid fluctuation of the sum signal. Consequently, the rapid fluctuation of the level for a short time is removed and the generation of turbulences in the focusing servo and the tracking servo is prevented.

Title: Method and device for radio packet communication
Inventor: KAYAMA HIDETOSHI
IPC: H04B7/26
Filed: 1995-02-02
Abstract: PURPOSE: To cooperatively operate the idle line control access and the split tree algorithm by inhibiting transmission of newly occurring incoming packets in the case of collision of incoming packets on a packet channel and permitting retransmission of only the packets which have collided with each other. CONSTITUTION: If incoming packets simultaneously transmitted from two or more of mobile stations 2 collide with each other on the packet channel, a base station 1 reports a collision resolution signal besides an inhibition signal or an idle line signal. When the collision resolution signal is reported, each mobile station 2 inhibits transmission of up packets, which newly occur after the occurrence time of the packet which collide, and retransmits this packet. Thus, the idle line control is used or the idle line control and the reservation control are combined to efficiently perform the random access in the case of the absence of collition, and packets are efficiently retransmitted based on the split tree algorithm in the case of the occurrence of collision.
