Title: Method for transferring toner image
Inventor: HANEDA SATORU
IPC: G03G15/16
Filed: 1983-07-29
Abstract: PURPOSE:To enhance sharpness of an image by forming a toner image with toner particles each having a light transmitting part in illuminating the surface of the toner image attached to an image bearing body with light and transferring the toner image on a transfer material. CONSTITUTION:In illuminating the surface of a toner image with light before or during image transfer, the illumination light is easily transmitted even through a large stack of attached toner particles to an image bearing body, and electrostatic charge on the body is easily erased, and transfer efficiency is enhanced when the toner image is transferred by corona discharge or the like. A transparent resin is used for toner particles or a transparent resin is mixed with the toner particles to provide a transparent part in each toner particle. As a result, transfer efficiency is improved and a sharp good image is obtained by illuminating the toner image on the image bearing body to transfer the image.

Title: Solenoid valve control device
Inventor: UCHIUMI YASUTAKA
IPC: F16K31/06
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To reduce dispersion of working time due to manufacturing dispersion by prohibiting rising of a detection value of an electric current detection means beyond a specified electric current value until a specified period of time passes after voltage is applied on a solenoid coil and allowing rising of the electric current value at the time when the specified period of time passes. SOLUTION: Rising of an electric current value I beyond a specified electric current value Is is prohibited until a specified period of time Ts passes after voltage is applied on a solenoid coil. Thereafter, when the specified period of time Ts passes, rising of the electric current value I is allowed. Consequently, a fuel injection valve stands by once in a state before the fuel injection valve is actually opened until the specified period of time Ts passes, and thereafter, the fuel injection valve is actually opened. That is, dispersion of delay time is decided by time required for the specified electric current value Is to reach an electric current value Ia from an electrified stand-by state, and the specified period of time Ts is not concerned in dispersion of the delay time. Consequently, it is possible to reduce dispersion of working time.

Title: Brick for lining for container for molten metal
Inventor: ISHIKAWA MINORU
IPC: F27D1/08
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To relax the generation of a thermal stress due to repetition of heating and cooling by embedding a metallic wire vertically to a contact surface between an internal part and the molten metal, to cause breakage to hardly occur by increasing the strength of a brick, and further to cause a part, to which breakage occurs, to hardly fall even when the breakage occurs. SOLUTION: Metallic wires 1 are embedded at intervals of a specified distance through the overall length in a longitudinal direction of a brick, and an opening part 2 for inserting a tuyere is formed in a central part. In a case of a tuyere brick, since a thermal stress is generated vertical to a working surface, the embedded metallic wires reinforce a brick and prevents breakage of the brick. The material of the brick is not especially limited but may be magnesia carbon, and the other alumina carbon brick may be an alumina-SIC- carbon brick. The material of the embedding metallic wire is especially limited, and preferably a stainless steel being a material, such as SUS304 and SUS410, having high thermal conductivity.

Abstract: PROBLEM TO BE SOLVED: To provide an original reader which can surely remove a foreign matters such as dirt or dusts stuck on the reflection plane of the mirror. SOLUTION: Near a position facing a reflection plane 31 of 1st mirror 3, a tungsten wire 11 is installed on a 1st traveling body 8 at a position where the optical path of reflected light from an original (a) is not shielded. First of all, since mutually inverse voltages are supplied to the tungsten wire 11 and the reflection plane 31 of the 1st mirror 3, dusts on the reflection plane 31 is charged. Afterwards, a control circuit 18 controls a high voltage power source 17 for the 1st mirror so that the output voltage of the high voltage power source 17 for the 1st mirror can become a turned-on/off voltage. Therefore, the dusts stuck and charged on the reflection plane 31 is attracted to the side of the tungsten wire 11 and stuck on the tungsten wire 11. Thus, the reflection plane 31 of the 1st mirror 3 is prevented from shielding light.

Abstract: PURPOSE:To rotate a rotor securely even if a shift in phase is caused as a result of hand correction, by generating out-of-phase hand advance pulses when the advancing operation of a step motor by the 1st hand advance pulse is not performed after time adjustment. CONSTITUTION:If a step motor is not in phase after time correction is made by driving the rotor of the step motor through an external operating member, the motor is not driven even if the 1st hand advance pulse is applied through a  motor driving circuit 6 to the coil 7a of the step motor. Therefore, no counter  electromotive force is not generated at the coil 7a and the resetting of a correction storage circuit 10 through an operation detecting circuit 8 is not performed. Consequently, a correction signal generator 5 generates a pulse out of phase with the hand advance pulse and the step motor is driven through the circuit 6 to perform phase matching. As a result, even if a shift in phase is caused as a result of hand correction, the rotor of the step motor is rotated securely.
