Title: Electrostatic latent image developing toner and image forming method
Inventor: YAMADA HATSUMI
IPC: G03G9/09
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To prevent the decrease of image density and the occurrence of fog or image defects such as black spots and out-of-focus when images are repeatedly formed by controlling fine particles to have a specified average particle size on the volume standard and to include particles having twice or more of the average particle size by specified volume ratio in the distribution of particle size. SOLUTION: The inorg. fine particles in the toner consist of, for example, silica and titanium oxide. It is necessary that the inorg. fine particles have 0.1 to 0.4μm average particle size (D) by the volume standard and that particles having 2×(D) particle size are included by 5 to 20vol.% in the distribution of particle size by the volume standard. When particles having 2×(D) particle size is included by <5vol.%, large particles are less present and a proper polishing effect on a photoreceptor can not be obtd. If the proportion exceeds 20vol.%, large particles are too much, which causes such problems as scratches on a photoreceptor due to an excess polishing effect and as decrease in the rising effect of electrification due to decrease in the electrification effect.

Title: Stepping motor driving device
Inventor: MISUMI HIROYOSHI
IPC: H02P8/12
Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To positively drive an FET for allowing a coil current to flow without requiring any minus power supply, by constantly maintaining a coil current that flows from a drive part to a stepping motor, and controlling the grounding potential of the drive part. SOLUTION: Vref when current is constant is given to a control part 1 from a control signal input terminal 7, and the rotary speed of a motor 6 is set, thus starting the motor. The excitation pattern signal for driving the motor is generated according to an instruction from the control part 1, thus outputting a+ to e+ and a-to e-. Each excitation pattern signal enters pull-up A part 4 and B part 20, is set to a proper voltage, and allows a current to flow to the coil of the motor 6 according to an excitation pattern being inputted to an FET in a drive part 5 for rotation. In this case, a middle-point potential being applied to the drive part 5 is adjusted to Vadj at a potential adjustment part 30, a-side potential is adjusted, a voltage being applied between + and-is minimized according to speed and current values, and the FET can be turned on within the range.

Title: Stairs using non-slip on tread
Inventor: KONDO UEHIKO
IPC: E04F11/17
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To prevent an accident of making a false step by providing a level difference surface on one end of a tread to form a lifted surface at a location higher than a reference surface, and forming a folding portion at an opposite end to the lifted surface, so as to face the ground. SOLUTION: In stairs consisting of treads and handrail portions, at the time of forming the treads, a level difference surface is formed, to thereby provide a lifted surface 1 at a location higher than a reference surface 3. Further, to accelerate to natural dropping of raindrops, a folding portion 4 is formed on one end opposite to the lifted surface 1, in a manner facing the ground when installed, at the time of forming the treads. Next, when one walks up and down the stairs, he walks down the stairs while making sure that his heel makes contact with the reference surface 3 and his toe base makes contact with the lifted surface 1. Therefore, a possibility of an accident of falling or tumbling due to loosing his footing can be decreased.

Title: Terminal structure of transformer and forming method of terminal
Inventor: NODA HIROSHI
IPC: H01F27/28
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To obtain a terminal structure of a transformer which features simple working processes, possible price reduction, low DC resistance, and high performance of the transformer, and to obtain a forming method of the terminal of the transformer. SOLUTION: A coil is divided into one or a plurality of flat type wires which are worked by clockwise or counterclockwise rotation in the direction of the plane of the flat type wires. The coil forms at least a primary winding and a secondary winding respectively. The primary and the secondary windings are inserted into a ferrite core 3 successively to form a magnetic circuit. For the flat type wires which are derived from the ferrite core 3, a primary bending 1-1 is conducted at a point of a fixed length in the direction of the lower part of the ferrite core 3, and then a secondary bending 1-2 is conducted at a point which has reached the lower plane of a transformer in a horizontal direction. Consequently, a first terminal 1a is formed by cutting the flat type wires with a fixed length. Likewise, a second terminal 1b is formed.

Title: Capacity regulator of blower
Inventor: ENDO KO
IPC: F04D29/46
Filed: 1994-09-26
Abstract: PURPOSE: To provide a simple structure capable of easily regulating capacity by disposing a sound absorbing material in the inlet port side of a capacity regulating plate provided opposedly to the inlet port of a casing having a rotary blade pivotably disposed, while the plate can slide to the inlet port side. CONSTITUTION: A motor 8, when driven, rotates a shaft 5 through a pulley.belt, rotates a rotary blade 2 fixed to the shaft 5, sucks air from an inlet port 3 into the casing and dischage the air from an outlet port 4. Then, a clearance between the inlet port 3 and a capacity regulating plate 11 opposed thereto provides a substantial air inlet port area. Thus, when a large blow capacity is needed, the capacity regulating plate 11 is moved on the shaft to be separated from the inlet port 3 and fixed by a fixture. When the capacity is regulated to a small capacity conversely, the capacity regulating plate 11 is adapted to approach the inlet port 3. When the sucked air capacity becomes small, the air velocity near the inlet port is increased to generate noises which however are absorbed by a sound absorbing material to be reduced.
