Title: Electrostatic latent image developer and electrostatic latent image developing method using the same
Inventor: SATO KISHO
IPC: G03G9/083
Filed: 1994-07-14
Abstract: PURPOSE:To enhance the sharpness of lines and characters by making it effectively suppressing fogging on non-image printed parts by electric field control agents in an electrostatic latent image developer and effectively executing development faithful to the latent image formed on a photoreceptor. CONSTITUTION:This electrostatic latent image developer is prepd. by compounding specific carriers 36, toners 40 and electric field control agents 38 at a ratio of the carriers: the toners: the electric field control agents =50 to 80%:10 to 40%:5 to 40%, by weight. The average particle size of the electric field control agents 38 is within a range of 5 to 30mum. The average particle size thereof is smaller than the average particle size of the carriers 36 and the electric field control agents are electrostatically charged to a polarity reverse from the polarity of the toners 40 and, therefore, the fogging on the non-image printed parts is effectively suppressed by the presence of such electric field control agents 38. Since the faithful adhesion of the toners 40 to the electrostatic latent image formed on the photoreceptor 10 is possible, the sharpness of the characters or lines is effectively improved.

Title: Optical switch circuit
Inventor: SUZUKI FUMINORI
IPC: H03K17/78
Filed: 1981-10-13
Abstract: PURPOSE:To assure a switching operation without causing chattering, by providing hysteresis characteristics to the inverting action of an inverter that produces an optical switch signal. CONSTITUTION:The main body 6 of a timepiece circuit can receive a signal PS from an optical switch circuit 1 via a switch (not shown in the diagram) in addition to its original timing action. When illumination light is weak to the circuit 1, the voltage generated from a solar battery 2 has a low level and is then lowered less by a load resistance 3a. The input voltage of an inverter 5 is set at a level close to the positive potential of a battery 7, and the output of the inverter 5 is set at a low level. As a result, a switch 4 is turned on and a resistance 3b is turned into a load. Thus the above-mentioned state progresses further. While the inverter output is set at a high level with the switch 4 turned off in case the illumination light is intensive. In such a way, the hystresis is secured to the inverting action of the inverter 5 in response to the intensity of the illumination light. Therefore the optical switch circuit 1 never has chattering.
