Title: Electrophotographic copying device
Inventor: HIRANUMA SUSUMU
IPC: G03G21/06
Filed: 1979-10-01
Abstract: PURPOSE:To prevent white blank at the copy tip and make it possible to remove electricity at the tip of the transfer material, by providing corona electrodes for auxiliary transfer, transfer, and separation to eliminate the retransfer phenomenon. CONSTITUTION:Auxiliary transfer corona electrode 5, transfer corona electrode 6, and separation corona electrode 7 are provided, and discharge polarities of respective electrodes are set as shown in table I, and a timer and so on are used to perform the discharge sequence of each electrode by a discharge polarity switching device and so on. In respect to the toner image and photoconductive surface potential after development, the charged polarity of the toner at the tip of the picture is inverted and becomes the + potential. Next, when transfer material 8 reaches transfer electrode 6, only the picture body part is transferred; and when the tip of material 8 reaches electrode 7, the tip toner image is sucked and transferred to the transfer material 8 side. As a result, the retransfer phenomenon can be eliminated, and white blank at the copy tip can be prevented.

Title: Driving tool having no-load operation preventive mechanism
Inventor: AZUMA TAKETO
IPC: B25D17/10
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a driving tool having a no-load operation preventive mechanism capable of properly preventing the no-load driving operation of a tool part, maintaining the strength of a hammer and avoiding the deterioration of a no-load driving preventive function. SOLUTION: A hammer 4 travels in the direction of an arrow 90, with a tool part 10 kept off a machining object, and an air hole 11 is communicated to the first chamber 21. As a result, the hammer 4 does not easily move concurrently, even when the travel of a piston 3 takes place. An air hole 13 communicated to the second chamber 22 is provided with a nonreturn valve 14. The air is thereby made to flow externally from the second chamber 22, but not to enter the chamber 22. As a result, the hammer 4 does not travel in the direction of an arrow 91, but only in the direction of the arrow 90. According to this construction, the rebound of the hammer 4 is restrained and the prevention of the no-load driving operation of the tool part 10 is ensured.

CONSTITUTION:A transmission shaft 32 is rotated when a motor 31 is powered, each of bevel gears 34 and 35, and bevel gears 26 attached on a driving shaft 22 by way of the driving shaft 22 are consequently rotated permitting a conveyor wheel 5 to be simultaneously rotated, since these bevel gears are in mesh of a bevel gear 21 of the inner wheel 8 in each of conveying wheel 5. Accordingly, a cargo starts being conveyed, when placed on a group of conveying wheel 5 which is arranged on the both sides. In this case, a partial change in the conveying speed can be obtained by chaning the outer diameter, i.e. the number of the gear tooth of the bevel gear 21 of the inner wheel 8 in the conveying wheel 5 concerned. That is, decrease (increase) in the number of the gear tooth of the above-mentioned gear 21 results in increase (decrease) in the conveying speed.

Abstract: PURPOSE:To implement high reliability, by using a piece of wire, on which noble metal is plated. CONSTITUTION:A piece of Al or Cu wire, on which Au is plated, indicates high corrosion resistance as a piece of Au wire and can be applied for plastic sealing. With respect to corrosion at the bonding part of the Al wire and a lead frame, the wire, on which Au or Ag is plated, is used. The wire is connected to the lead frame by applying ultrasonic waves on the wire. The plated metal is not exfoliated from the Al wire, on which Au or Ag is plated, by the ultrasonic waves. Therefore, the bonding strength between the plated metal and the lead frame, on which Ag is plated, is high and corrosion does not occur. Thus, high reliability is implemented.

Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To make an accurate timepiece display by synchronizing clock generated by a digital PLL, with synchronizing signals supplied from a digital network, and putting clocking counters in action, making use of this clock. SOLUTION: A digital PLL 71 oscillates crystal at the frequency of 15.36 MHz, for instance. An ISDN line 8 of a digital network inputs signal frames approximately every 2.5 ms, and frame synchronizing signals are detected by a frame detecting part 73. The digital PLL 71 synchronizes its own signals with the frame synchronizing signals. The synchronizing signals are divided by a frequency divider 72 to obtain signals of various frequencies. An 8 kHz signal out of these signals is outputted to a frequency divider 4 in a gate array 5, divided and outputted as one-second signals to a timepiece counter 1. Minute signals are generated from decimal and seneary counters, and hour signals are further generated by the decimal and senary counters. The hour signals are counted by the decimal and binary counters, and all the counters are cleared upon indicating twenty-four hours.

Abstract: PURPOSE:To certainly perform separation between paper sheets by forming a corrugation with an elastic body and exposing it from between belts. CONSTITUTION:A corrugation 27, formed by an elastic body and provided on the upper face of a vaccum box 25, is given the role of a normal corrugation 27 at the time of feeding paper with small rigidity such as thin paper and the like, while at the time of feeding paper with large rigidity such as thick paper and the like, a corrugation 29 is deformed by means of sucking force by the vacuum box 25 and paper so that the paper 28 is closely adhered onto the conveyance belt 22 to raise sucking efficiency. Accordingly, a gap 29, allowing a jet stream to blow in at the time of feeding thin paper, can be sufficiently secured between sheets. This leads to not only certain separation between sheets but also improvement of sucking efficiency of the vacuum box due to adhesion of paper to the belt at the time of feeding thick paper, and a big blower is not required.
