Title: Optical device
Inventor: ONO TAKEO
IPC: G02F1/025
Filed: 1990-10-27
Abstract: PURPOSE:To realize a function that, in a wavelength range, the absorption does not change but only the refractive index changes due to the application of voltage, by a method wherein the width of a deeper quantum well is configured narrower than that of the shallow quantum well. CONSTITUTION:A nonsymmetric quantum well layer 33 is configured in such a way that a barrier layer 43 is positioned between two wells 41, 42, both sides are made barrier 44 to form tow quantum well layers being multi-quantum well. Light is combined to a well layer having higher refractive index 33 from outside to guide the wave. The wavelength dependency of the absorption coefficient of this well layer having this structure in each applied voltage does not change little due to the changes in voltage. On the other hand, the wavelength dependency in each applied voltage of the changes in the refractive index due to the electric field in this instance shows the change in a degree of a specified value also in the light less than the specified value eV having lower absorption. Moreover, when the length of the waveguide is specified, and light with a specified wavelength is guided in this waveguide, only a specified applied voltage is required to pi-modulate the phase, with the fluctuation of the intensity of the optical output being maintained within a specified value, thereby making it possible to realize a phase-modulation element with a high degree of modulation and stable output.

Title: Manufacture of varistor
Inventor: TAIRA HIROAKI
IPC: H01C7/10
Filed: 1988-11-16
Abstract: PURPOSE:To obtain a varistor excellent in a non-linear coefficient in a high current region by a method wherein a specific amount of an element selected from group III or its oxide is added to ZnO for heat treatment to make ZnO semiconductive followed by crushing for making material powder to be molded into a desired shape and baked so as to obtain a sintered body. CONSTITUTION:Not less than 0.01mol% and not exceeding 5mol% of an element selected from group III or its oxide is added to ZnO for heat treatment to make ZnO semiconductive and crushed. Next, an auxiliary component functioning as varistor is added to make raw material powder and this raw material powder is molded into a desired shape and sintered to obtain a sintered body. In this case, when an amount of addition is less than 0.01mol%, almost no semiconductive effect is obtained and in case 5mol% is exceeded, instead a varistor characteristic is worsened. As a result, when resistance value is lowered by heat treatment, especially by solid solution of an addition metal in ZnO to reduce resistance value, a non-linear coefficient can be so much enlarged. Thereby, the non-linear coefficient in a high current region can be sharply improved so as to obtain the varistor excellent in a surge absorption characteristic by lowering limit voltage.

Title: Image forming method
Inventor: YOSHIHARA YOSHIYUKI
IPC: G03G15/00
Filed: 1994-11-24
Abstract: PURPOSE: To prevent image fogging from occurring and to always stably obtain high image quality by controlling an electrostatic charge member to be a DC constant voltage when the electrostatic charge member directly corresponds to the non-image forming area of a photoreceptor and detecting the quantity of a DC current corresponding to the film thickness of the photoreceptor and controlling the electrostatic charge member to be the DC constant voltage by the quantity of the DC current based on the detected result when it corresponds to the image forming area of the photoreceptor. CONSTITUTION: In the case of the film thickness of the photoreceptor is thinned because the surface of a drum is shaved because of endurance, the DC current detected in the control term of the DC constant voltage executed when an electrostatic charge roller 2 corresponds to the non-image forming area surface of the drum 1 becomes high and an image forming action is executed by electrostatically charging the image forming area surface of the drum 2 by the roller 2 in a state where the roller 2 is controlled to the DC constant voltage by drop-correction voltage corresponding to the detected DC current. Besides, toner is developed to a toner supply body by the drop-correction voltage corresponding to the detected DC current. By dropping surface potential by correcting the impressing voltage, an electric field is suppressed to be excessively strong.

IPC: B21D5/02
Filed: 1989-11-09
Abstract: PURPOSE:To take out a work easily, safely and smoothly by providing a projecting member with which the bend surface of work is supported in the state that the work is lifted upward from the upside of die by projecting it upward from the upside of die when the work is taken out of between a punch and a die after an end of bending. CONSTITUTION:The projecting member which is projected upward from the upside of the die 2 when the work W is taken out is provided. A work bending can be made in the state that it is lifted from die grooves when the work is taken out and the work can be easily taken out of between the punch 1 and the die 2. The takeout of work is smoothly done by arranging the rollers 16 for carrying in/out the work in the approximately same level to the upside of the die. The projecting member is constituted of a pin member 5 with a rounded tip and the work isn't applied with excess force because the projecting member is controlled its inclination so as to freely appear and disappear from the upside of the die and excess force is absorbed by performing the inclination to the pin member 5 with an air cylinder. In this way, even if the work is relatively large size, a bend part is easily knocked out of the die gooves and safely taken out and an automation line is achievable.
