Title: Image signal processor
Inventor: KUMAKAWA TOSHIAKI
IPC: H04N1/409
Filed: 1986-07-15
Abstract: PURPOSE:To decrease an unevenness that may occur in a contour part of a line drawing and the rounding that may occur at an intersection part by deciding the value of the image signal of an attended picture element among the image signals corresponding to a group of picture elements neighboring each other, based on the image signals of picture elements. CONSTITUTION:A binary image signal DO whole '0' replesents white and '1' black is supplied to an image delay element 2A and line delay dlement 1A so that five- picture-element-share of image signal groups DA, DB, DC, DD, and DE which are one-picture-element-delayed on after another are supplied to a decision circuit 6A. The decision circuit 6A sets the image signal D2-2 as an attended picture element data, and outputs data S1 and S2 corresponding to a pattern that the said data and surrounding picture element data jointly form. In case the data S1 and S2 both are '0', a selector 5A selects '0' for white-processing, but in case the S1 is '1' and the S2 is '0', the selector 5A selects '1' for black-processing, and if both are '1', selects the image signal D2-2 and outputs it as an image signal D5. The image signal D5 is processed by a second image signal processing means in the same manner as a first image signal processing. The recessed and projected part in the contour part of a line drawing is dereased by the first processing, and the rounding at an intersection part of the drawing is decreased by the second processing.

Title: Lighting device
Inventor: KANEKO ISAMU
IPC: G02F1/13357
Filed: 1987-07-03
Abstract: PURPOSE:To obtain a uniform brightness distribution as a plane light source by constituting a light device so that respective groove wall surfaces of a Fresnel surface facing the linear light source side increases in inclination gradually away from the linear light source. CONSTITUTION:Couples of linear light sources 1 and photoconductors 2 are arranged at right and left symmetrical positions and the Fresnel surface 2b of the photoconductor 2 is so constituted that its respective groove wall surfaces increase in inclination gradually away from the linear light sources 1. Therefore, the incident angle of light on the respective groove wall surfaces of the Fresnel surface 2b from the linear light sources 1 decreases away from the linear light sources 1, so the spread of its reflected light decreases away from the linear light sources 1. Further, this operation even on light incident on the Fresnel surface 2b after being reflected totally by the top surfaces 2c of the photoconductors 2 temporarily is similar. Consequently, the uniform brightness distribution is obtained as the surface light source and the thickness is reduced.

Title: Manufacture of printed wiring board
Inventor: OYAMA TATSUYA
IPC: H05K13/06
Filed: 1990-06-26
Abstract: PURPOSE:To freely vary a pressing force of a stylus during securing of an insulated wire by controlling a pressing force of an ultrasonic wave energizing stylus to a conductor in response to the surface of a board and the vertical deviation of the secured wire. CONSTITUTION:When a stylus 6 is disposed on the surface of a board, an output voltage becomes maximum, and as a deviation is increased, the voltage is reduced. When this voltage is amplified and applied to an electromagnetic coil 3, a load becomes maximum when the stylus is disposed on the board, and the load can be reduced at the crossing point of insulated wires 7 or further at the time of multiple crossing points. A time of supplying a current and for the coil 3 to respond is very fast such as 1ms. When a wiring speed is 150inches/ min, a wiring passage time of triple crossing points is 15ms. Accordingly, when a deviation is detected at a moment in which the crossing point is overridden and a signal is sent, the pressing force can be sufficiently controlled at the crossing point.

Title: Optical head
Inventor: SENDA NAOMICHI
IPC: G11B7/135
Filed: 1988-07-05
Abstract: PURPOSE:To prevent stray light, which is caused by reflection on a facing surface and reflection from a monitor optical detector, from being incident to a signal optical detector by inclining the surface, which faces to the monitor optical detector of a beam splitter, to the optical axis of an optical beam which advances from a light source to an optical disk surface. CONSTITUTION:A beam splitter 20 is formed with inclining the angle of an upper surface, at least, by theta to the optical axis of a beam 3. By forming the beam splitter in such a way, a reflected light (stray light 11a) on such an upper surface 12a is reflected in a direction which is inclined by 2theta to the optical axis of the stray light in the case of not-inclination. A reflected light 4 is refracted on the upper surface 12a, goes to be a beam 4a and incident to a monitor optical detector 13. Then, one part of the reflected light is reflected on the surface of the monitor optical detector, goes to be a stray light 14a and advances. This stray light 14a and the stray light 11a are separated from an original signal light 9 in position. Then, a signal detector 10 to be arranged on a signal optical axis can photo-detect only an original effective signal wholly without receiving the influence of the stray lights 11a and 14a.
