Patent JP-S6310134-A (JP)
Title: Waveguide type optical switch
Inventor: OKAYAMA HIDEAKI
IPC: G02B6/12
Filed: 1986-07-01
Abstract: PURPOSE:To reduce a loss of light in a bar state, without increasing a crosstalk in a cross state, by providing an intermediate refractive index area in the vicinity of an intersection part. CONSTITUTION:In case of a cross state, a light beam which is inputted from 1a or 2a of one end of a waveguide 1 or 2 travels straight through an intersection part 12, and outputted from the other end 1b or 2b of the same waveguide part. When a voltage is applied to an electrode 4, a refractive index of an area 3 falls, goes to a bar state, and the light beam which is inputted from one end part 1a or 2a of each waveguide 1 or 2 is brought to a total reflection by an interface to the area 3, and outputted from the other end part 2b or 1b of the different waveguide 2 or 1. In such a case, a part of the light beam passes through intermediate refractive index areas 5a, 5b, and the intermediate refractive index areas 5a, 5b expand effectively width of the waveguide in the intersection part, therefore, a loss of the light beam in the bar state is reduced. On the other hand, in case of the cross state, a crosstalk increases a little, but the refractive index of the areas 5a, 5b is lower than the refractive index of the waveguides 1, 2, therefore, the crosstalk does not become larger than usual.

Title: Electrostatic recorder
Inventor: MASUDA KOJI
IPC: G03G15/05
Filed: 1986-07-01
Abstract: PURPOSE:To contrive a uniform recorded density, by setting an ion recording output to be higher at outside parts of an electrostatic recording head than at a central part of the head, with respect to the circumferential direction of a latent image support drum. CONSTITUTION:For example, ion leading-out controlling means 3 (C1, C2, C3, C4) and ion generating sources 2 (G1, G2, G3, G4) are disposed opposite to a latent image support drum 4, the means 3 being nearer to the drum 4 than the ion generating sources 2. Ion recording outputs from 16 dots formed are controlled by combinations of ON/OFF signals of the ion leading-out controlling means C1-C4 with ON/OFF signals of the ion generating sources G1-G4. DC voltages from DC power sources P2, P3 are applied to the ion generating sources G2, G3 located at central parts near the center of the drum, whereas voltages from DC power sources P1, P2 higher than those from the DC power sources P2, P3 are applied to the ion generating sources G1, G4 located on the tip part sides. With this construction, the charge density of a latent image formed on the drum 4 becomes distributed uniformly with respect to the circumferential direction of the drum 4.

IPC: C03B35/16
Filed: 1989-06-15
Abstract: PURPOSE:To prevent the generation of backlash in the variation of transfer speed and to easily take the countermeasure in the case of damage of a transfer roll by applying rotary force via an endless belt to a transfer roll for transporting a plate glass in horizontal direction and making the transfer roll movable in vertical direction. CONSTITUTION:A number of transfer rolls 10 are arranged in such a manner as to cross their shafts perpendicularly with the transfer direction of a plate to be transferred and to form a horizontal transfer face with the upper end of each transfer roll 10. Both ends of each transfer roll 10 are supported with bearings 11, 12 put into a notch 9 formed on a receiving plate 8. The motions of the transfer roll 10 in transversal and transportation directions are inhibited and the roll is made to be movable exclusively in vertical direction by this structure. An endless belt 2 is placed under the transfer roll 10 in a state contacting with the transfer roll to apply rotational force to the transfer roll 10. When one of the transfer rolls 10 is damaged, a vertically adjustable supporting roll 15 supporting the endless belt 2 from under is lowered to lower the transfer roll 10 and the damaged roll is replaced.

According to it, a voltage at a point C is changed, and the potentials at the point E and point F are always made equal. Since current values i2 and i5 are decided by resistances R2 and R3, the ratio of the currents i2 and i5 are fixed. Since a current i7 is changed according to the i5 when a transistor Q1 is on, the current i7 has the same temperature characteristic as a current i9.
