CONSTITUTION: At the time of producing a galvanized steel sheet, a plating original sheet subjected to degreasing and pickling is applied with galvanizing of 5 to 100mg/m<2> coating weight at >=100A/dm<2> current density as a primary layer. Next, it is applied with galvanizing of 0.5 to 1g/m<2> coating weight at 10 to 100A/dm<2> current density as a secondary layer, and after that, the secondary layer is dissolved by 0.1 to 0.5g/m<2> in an acidic galvanizing bath. After that. it is furthermore applied with galvanizing at 10 to 100A/dm<2> current density as a third layer to regulate the total of the plating layers to 5 to 100g/m<2> .  Thus, the generation of plating nuclei in the initial stage is increased, the plating nuclei can be generated even in flaws and stain parts similarly to the case of normal parts, new nuclei are generated while the plating is grown at medium current density, and abnormal growing crystals can be removed away by the dissolving.

Abstract: PURPOSE: To reduce the height of an accumulator case and make thinner the same by providing an oil return pipe among a cylindrical ring having a refrigerant passage in a gas/liquid separation chamber and filled with a metal brush shaped wire, a discharge pipe, and a bottom. CONSTITUTION: A gas/liquid separation chamber is provided in a laterally formed accumulator case 1. A gas/liquid mixed refrigerant flowing into the gas/liquid separation chamber 2 from a suction pipe 3 flows into a cylindrical ring 6 where a liquid fraction collides a wire 7 and only liquid is dropped on a bottom of the gas/liquid separation chamber 2 while gas flows from a refrigerant passage 5 to the gas/liquid separation chamber 2 on the side of a discharge port 8 for gas/liquid separation. The separated gas refrigerant is discharged from a discharge pipe 4.  In contrast, although the dropped liquid refrigerant and oil contained in the former are accumulated on the bottom of the gas/liquid separation chamber 2, when a certain amount thereof is accumulated, the liquid refrigerant and the oil are sucked from an oil suction hole 10 in the oil return pipe 9 and are guided to a discharge pipe 4, and are mixed with the gas refrigerant and discharged. Flow rates of the liquid refrigerant and the oil flowing through the oil return pipe 9 are determined by a pressure difference between the gas/liquid separation chamber 2 and the discharge pipe 4, a level of the accumulated liquid refrigerant level, and an inner diameter and a length of the oil return pipe 9.

Title: Air-fuel ratio control device for internal combustion engine
Inventor: HIBINO YOSHITAKA
IPC: F02D41/00
Filed: 1986-10-30
Abstract: PURPOSE:To aim at improvement in drivability, by making a renewal period of command output value for feedback control to be target speed of engine speed longer as compared with that of the output value of air-fuel ratio feedback control at the time of engine's idle running. CONSTITUTION:At the time of the idle running, if an engine speed feedback control condition is satisfied, a command output value CMD is increased or decreased and renewed according to a deviation between the target speed and the equalized speed of engine speed at every specified time t5. Within the specified time t5, so far as the engine speed feedback condition is satisfied, the same command output value CMD is fed to a drive circuit 38b at every specified period T1. Accordingly, when the engine speed feedback control condition is satisfied, air-fuel ratio feedback control takes place so that the engine speed is controlled for feedback at each very long period t5 as compared with the specified period T1 or the renewal period of the output value, thus the engine speed is controllable to be target speed so as not to cause the increase of decrease of a fuel supply to vary an air-fuel ratio.

Title: Electrostatic recording device
Inventor: NAKAZAWA TOSHIHIKO
IPC: G03G15/04
Filed: 1984-12-10
Abstract: PURPOSE:To prevent bundle lines which supply recording signals to respective exposure heads from entwining and twisting even when an exposure scan is made continuously by fitting the bundle lines to a rotary connector, and rotating the rotary connector periodically in a fixed direction. CONSTITUTION:For example, when an exposure head 12 begins to make an exposure scan on a photosensitive belt 1 through the rotation of a timing belt 11, signal bundle lines 19 and 21 connected to exposure heads 12 and 13 also move following it and a rotating shafts also rotates in one direction. At this time, the rotation part 22a of the rotary connector 22 does not rotate and stops because a claw 29 engages a cut 25 formed in its outer periphery as shown in a figure (b), so a coil spring 27 is deformed winding around the rotating shaft 23 through the rotation of the rotating shaft 23 and thus charged with spring force. When a solenoid 30 is excited when the exposure head 12 finishes making the exposure scan on the photosensitive belt 1, the claw 29 disengages from the cut 25 of the rotation part 22a against the force of a spring 28, so it is rotated in one direction (arrow C) with the spring force charged in the coil spring 27 so far.

Title: Intermittent conveying device
Inventor: HARA MASAYUKI
IPC: B65G25/12
Filed: 1991-09-10
Abstract: PURPOSE:To convey plural bodies to be conveyed all at once intermittently at a fixed pitch by engaging a bar with a holding-moving active piston in order to press and move the bar in the circumferential direction which is concentric with a cylinder tube. CONSTITUTION:When a body 16 to be conveyed is placed in the specified position of a straight conveying guide 15, a holding-moving active air-cylinder 30 is operated to move a holding-moving active piston 33 to the right. Then, a bar 25 engaging with the engaging groove 35 of the holding-moving active piston 33 is pressed and moved in its attitude parallel to a cylinder tube 1 to turn a slider 5b and a holing body 20 counterclockwise. When the holding- moving active piston 33 is moved to the left while pressing the bar 25 by the action of the holding-moving active air-cylinder 30, the holding body 20 is turned clockwise to be released from the body 16 to be conveyed. When a movement restricting piston reaches a position close to a sensor, the movement of the holding-moving active piston 33 is stopped by a detected signal from the sensor, and thus the holding body 20 stops its turning in its holding-released attitude.

Filed: 1988-10-14
Abstract: PURPOSE:To minimize the temperature rise of a motor or a solenoid by moving width adjusting plates each time that papers to be contained in a paper containing tray are increased by the prescribed number of papers. CONSTITUTION:In double-sided copy, a tray switch 17 changes according to activating or nonactivating condition determined by the detection of a copying paper which enters into a tray 1. And the number of times the tray switch 17 is turned on, that is, the number of papers to be contained in the paper containing tray 1 is counted, and the counted value is judged whether it is an even number or an odd number. With the even number the width adjusting plates 2 and 3 are activated to arrange neatly the width of the papers to be contained in the paper containing tray 1; with the odd number a paper is judged whether it is the last one to be contained in the paper containing tray 1 or not, and the width adjusting plates 2 and 3 are activated when the paper is the last one. This prevents the temperature of the driving means from being excessively raised.
