IPC: C25D21/14
Filed: 1990-03-28
Abstract: PURPOSE:To control the dissolution of contained impurities and to supply a stabilized plating soln. by obliquely arranging many metallic pieces contg. a metal and a metal nobler than the former in a dissolving tank away from one another and injecting a plating soln. from the lower part toward the upper part. CONSTITUTION:A metal ion is supplied to the plating soln. with the concn. of metal ions reduced in Zn-Fe alloy plating. When the metal ion is supplied, one or more metallic pieces 13 contg. Zn and Fe and the Pb, Cd, etc., nobler than the Zn and Fe as impurities 16 and inclined to horizontal are arranged in the dissolving tank 12 away from one another. The piece 13 is arranged through a horizontal shelf 14 having a through hole 18 and an inclined rack 15 having a through hole 19 on the shelf. A plating soln. 3 is then supplied from the injection port 7 from the lower part toward the upper part. Consequently, the base Zn and Fe are selectively dissolved, and the plating soln. contg. the ions is supplied to a plating device through an outlet 8. In this case, the flow velocity of the ion-contg. plating soln. in the tank 12 is preferably made lower than the settling velocity of the impurity particles.

Filed: 1991-03-22
Abstract: PURPOSE:To decrease a necessary inter-processor communication, and to reduce a communication cost by moving an exclusive arbiter of a message onto the same processor as a final target value. CONSTITUTION:When a position of a receiver 21 of a message in a processor being different from an exclusive arbiter 41 is informed to the exclusive arbiter 41, the exclusive arbiter 41 sends the message to the receiver 21 and requests to make a copy of the exclusive arbiter 41.

Title: Electromagnetic valve drive unit
Inventor: ARIKAWA FUMIAKI
IPC: F01L9/04
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To rapidly keep a valve in the closed state by shortening free lengths of a first and second springs facing to each other, and deviating an armature from the center between a first and a second solenoids facing to each other at the time when the current is not fed, in an electromagnetic valve drive unit equipped with a valve-opening side spring and a valve-closing side spring. SOLUTION: A valve 1 is opened or closed by driving a first and a second solenoids 2a, 2b, through a solenoid driving means 11, by a solenoid driving timing deciding means 12 by which a detection signal of a piston position of an engine 10 is inputted. In this case, the position of an armature 6 is deviated by its own weight to the opened-valve side at the time when the current is not fed to the first and the second solenoids 2a, 2b, by shortening free lengths of a first and a second springs 3a, 3b, respectively, which are installed corresponding to each solenoid 2a, 2b. Consequently, an aperture between the first solenoid 2a on the opened-valve side and the armature 6 is narrowed and a pulling force, namely, a keeping force of the valve in the closed state, generated by current feed to the solenoid 2a, is enhanced.

Title: Dynamic focus device
Inventor: KITATSUME SATOSHI
IPC: H04N3/26
Filed: 1993-04-08
Abstract: PURPOSE:To obtain a proper dynamic focus voltage even for plural horizontal frequencies by adding an amplitude control means of an output voltage to a transformer which transforms the modulation voltage having a horizontal deflection frequency to a desired dynamic focus voltage and controlling the amplitude of the transformer output voltage in accordance with the horizontal deflection frequency. CONSTITUTION:In the case of plural horizontal deflection frequencies, the value of a capacitor 6 for S correction with the capacity switching function is switched by horizontal deflection frequencies to generate a parabolic voltage waveform whose amplitude is different by horizontal deflection frequencies. This parabolic voltage waveform is boosted by a transformer 15 with the output voltage amplitude control means and is inverted if necessary. At this time, the tap of the primary winding or the secondary winding of the transformer 15 is switched in accordance with horizontal deflection frequency. Thus, a dynamic focus voltage 13 having a fixed amplitude is outputted from the transformer 15 independently of horizontal deflection frequencies.

Title: Radio transmitter and receiver
IPC: H04Q9/00
Filed: 1992-04-03
Abstract: PURPOSE:To provide a radio transmitter and a radio receiver in a compact size and at the low cost in order to reduce the manhour required for the address setting jobs without using any conventional address setting switch. CONSTITUTION:A conventional address switch can be omitted with use of a transmission address storage means 1 which stores the transmission address information on an EP-PROM contained in a microcomputer 102 of a transmitter 101. Furthermore the address of a receiver 110 can be automatically set with use of a reception address register means 2 which uses a specific transmission address that is sent to the receiver 101 from the transmitter 101 for the first time after the power supply of the receiver 110 is applied as the reception address information on the receiver 110. Thus the conventional reception address setting switch can be omitted. In addition, the address setting job needed to secure the coincidence between the transmission and reception addresses can also be omitted. Thus the working manhour required for the start of operation can be extremely reduced.

Title: Woven fabric of polyester-cellulosic conjugate fiber
Inventor: MATSUMOTO YOSHIKO
IPC: D06M101/16
Filed: 1994-04-20
Abstract: PURPOSE:To produce woven fabric of a polyester/cellulosic conjugate fiber having excellent handling without lowering the strength of the cellulosic fiber by carrying out the alkali thinning of woven fabric of the conjugate fiber without using desizing and scouring treatments of the fabric before the alkali thinning treatment. CONSTITUTION:Woven fabric (e.g. plain fabric, twill weave fabric or satin fabric) woven with a conjugate fiber produced by conjugating a cellulosic fiber to a polyester fiber is subjected, in a state coated with a sizing agent, to alkali thinning treatment by conventional method without desizing and scouring the fabric before the alkali thinning treatment. Woven fabric of conjugate fiber produced by this process keeps the original strength of the cellulosic fiber in contrast with conventional process. The process is especially effective on twill- textured woven fabric produced by using the conjugate fiber as a warp.
