Title: Image forming method
Inventor: YAMAMOTO HAJIME
IPC: G03G13/01
Filed: 1983-12-12
Abstract: PURPOSE:To obtain a sharp image by electrifying an electrophotographic sensitive body contg. a photoconductive material, sticking electrostatically light transmittable particles thereon, exposing an image to the photosensitive body from the particle surface side and electrifying the particles to the same potential as the potential of the exposed photosenesitive body then removing the exposed particles. CONSTITUTION:A photosensitive body 1 contg. a photoconductive material such as ZnO or the like formed on a conductive base plate 2 is electrified - by a corona electrifier 4 and thereafter light transmittable particles 5 consisting of an acrylic resin, etc. having the colored surface are electrostatically stuck on the surface of the body 1. The image of an original 6 is then exposed as shown by arrows. The particles 5 are electrified to approximately the same potential as the potential of the photosensitive body in the exposed part by using the scorotron electrifier 4 having a grid 4'. The adhesive force between the exposed particles 5 and the body 1 is thus made nearly zero and thereafter oscillation is applied to the body 1 faced downward by an exciter 7 to remove the particles 5a. The sharp copy free from a ground fog is thus obtd.

Title: Truck wheel
Inventor: KAJIWARA TOMOYUKI
IPC: B60B17/00
Filed: 1983-12-14
Abstract: PURPOSE:To reduce slip of a truck wheel which rolls on a circular track, on the rail thereof by splitting the wheel in the width direction thereof into a plurality of parts so that the parts may turn independently in close contact with each other. CONSTITUTION:A wheel 2 is splitted into three parts in the direction of the width thereof as that the individual parts turn independently in close contact with each other. When the wheel 2 rolls on the circular track, the internal and external parts with respect to a rail run at different speeds, however, since the wheel 2 is divided into three parts, they roll independently, thereby reducing the slip ratio to one third of the conventional ratio. The number of the parts is inversely proportional to the slippage so that the more the number thereof is increased, the more the slippage can be reduced.

IPC: H03K17/732
Filed: 1989-09-08
Abstract: PURPOSE:To prevent a driving current of a switching element to be controlled due to a voltage fluctuation of a DC power supply by devising the circuit such that a chopping switching element is driven by a hysteresis comparator operated by the output of a current sensing element and the said hysteresis comparator has a large limit when the control switching element is turned on. CONSTITUTION:When a switching element 1 to be controlled is turned on, a control switching element 11 is turned off and the detected value (both upper and lower limits) of a hysteresis comparator 15 is decreased simultaneously. A current set to a high level and flowing to a reactor 14 while the control switching element 11 is turned on is not rapidly decreased by the action of the reactor 14 and the hysteresis comparator 15 keeps the OFF state of the switching element 12 till the hysteresis comparator 15 reaches its lower limit. When the switching element 12 is turned on, a current I1 flows in a path shown in solid lines in figure and is a driving current for the switching element 1 to be controlled.

IPC: G09G1/16
Filed: 1984-11-09
Abstract: PURPOSE:To reduce ringing of a horizontal deflection current caused by the insertion of a linearity coil by adding a circuit where a resistor and a switching element are combined in parallel with the linearity coil. CONSTITUTION:A diode 15 is connected in series with a resistor 14 to block a current flowing to the resistor 14 at the blanking period. Since a capacitor 16 is connected in parallel with a stray capacitance 13 across the linearity coil 6, the ringing frequency is changed by changing the capacitance of the capacitor 16.

Abstract: PROBLEM TO BE SOLVED: To increase the bonding strength of a bump and prevent the bonding failure of the bump, by changing the shape of the bump formed on the front and rear planes of a board-shaped P-type and N-type thermoelectric semiconductor materials by plane. SOLUTION: A shape of a bump that bonds with a substrate is permitted to be square, which is almost the same as a square part left by cutting a thermoelectric semiconductor water 13 by a blade, and a bump 7 is used for a bonding process of a first time.

Abstract: PROBLEM TO BE SOLVED: To investigate communication passing through an exchange unit as regulation objects by individual time zones by referring to a regulation management information registration means by individual time zones and regulating the communication of the exchange unit in accordance with registered regulation management information when a congestion state occurs in the exchange unit. SOLUTION: When a maintenance man inputs the registration request of necessary congestion information by individual time zones (RT) from a maintenance terminal 16, a processing part 124 analyzes information RT and confirms the normality. When it is normal, the registration request of information RT is transmitted to a management part 127. The management part 127 stores information RT and a regulation condition Cr in an information area 132 and gives information to the processing part 124. The processing part 124 informs registration termination of the maintenance terminal 16 and the maintenance man recognizes registration completion. When a communication line control part 121 detects the congestion state of communication in the exchange unit 1, a management part 125 informs it to an execution part 122.  The execution part 122 requests the selection of the communication of the regulation object to a processing part 123. The processing part 123 requests the retrieval of congestion regulation information by individual time zones. The management part 127 informs congestion regulation information of the processing part 123. The processing part 123 informs a regulation object selection answer and the execution part 122 executes a regulation processing.
