Filed: 1984-07-20
Abstract: PURPOSE:To eliminate generation of residual material and realize certain clamping of a vice by providing a main vice in the rear of the material feed direction, with a cutting part interposed between itself and a feed vice located ahead, and letting said feed vice hold the front end of material and advance to feed the material according to the cutting length. CONSTITUTION:During cutting, a feed vice 13 is positioned in A and material W is held between a main vice 12 and the feed vice 13, while after cutting, the vice 13 advances by required distance, for example, more than the breadth of a mouth piece 13a while holding the cut off material piece W' and reaches position B. There, releasing the material piece W', the vice 13 promptly passes through the cutting part and retreats to position C and holds the front end part of the material W. At the same time, the main vice 12 is released and the feed vice 13 is advanced to the original position A to feed material, then the main vice 12 is clamped to perform the next cutting. Accordingly, even if the cutting length of material is small, the material piece W' is not left in both vices at the time of the next cutting and the length of residual material comes to be very small, therefore, clamping action is always certain and the yield rate is improved.

Title: Photoconductive photosensor
Inventor: NAKAYAMA SHOICHIRO
IPC: H01L31/0248
Filed: 1984-07-20
Abstract: PURPOSE:To improve the linearity of the output with respect to the amont of incident light, by making the optical forbidden band width of an i-type layer, which is virtually intrinsic, larger than that of an impurity layer. CONSTITUTION:An i-type layer 3i is provided in the center of a photoconductive film 3 which is sandwiched by first and second electrode films 2 and 4. Two n type impurity layers 3n1, 3n2 are respectively disposed on two main surfaces of the layer 3i. When the layer 3i is formed from. e.g., a(amorphous)-SixC1-x and the layers 3n1, 3n2 are formed from a-Si, the optical forbidden band width of the layer 3i becomes larger than that of the layers 3n1, 3n2 on account of the difference therebetween in terms of the film composition. Accordingly, when a bias is applied through lead members 5, 6, the forbidden band width difference acts so as to block carriers flowing in from the outside. In consequence, only a photocurrent in accordance with the amount of irradiation flows, and the linearity of the output with respect to the amount of incident light is improved.

Title: Liquid crystal color display device
Inventor: KATOU YOSHIAKI
IPC: G02F1/133
Filed: 1979-11-22
Abstract: PURPOSE:To obtain devices such as a watch having vivid luminescence and colors and a high inversion effect with a simple constitution, by combining the first polarizing plate of a neutral color,  two liquid crystal layers, and the second and the third color polarizing plates which have polarization axes orthogonal to each other and are different from each other. CONSTITUTION:Colorless, blue and red polarizing plates are used as the first, the second, and the  third polarizing plates; and if the polarization axis of the second polarizing plate is orthogonal to that of other polarizing plates, the transmitted light of the first polarizing plate 1 has the ground  part rotated at 90 by the second layer of liquid crystal cell 2, and the lighted pattern part is not rotated and reaches the second polarizing plate 3. Though the ground part passes through the  second polarizing plate because the polarization direction of the ground part agrees with the polarization axis direction of the second polarizing plate, only blue color permeates it because the  lit pattern part is orthogonal to the polarization axis direction of the second polarizing plate. In  the third polarizing plate 4, the last transmitted light of the ground part orthogonal to the polrization axis is colored with red. The blue light of the light pattern part transmits polarizing plate 4  because it is parallel with the polarization axis, and it is reflected by reflective plate 5, and thus, a  blue pattern is displayed on the red ground.

Abstract: PURPOSE:To eliminate an after image and to obtain a high saturated voltage value by forming a P-type impurity region near the surface of a photodiode, and forming the concentration of a P-type region of reading side high and the concentration of a channel stopper side low. CONSTITUTION:After a photodiode 3 and a channel stopper 4 are formed, they are patterned with resist 17 to ion implant only the photodiode 3, obliquely ion implanted to a reading gate side from one oblique direction with respect to a normal line, and a P<++> type region 13 is formed. Then, the stopper 4 side is obliquely ion implanted from the other oblique direction with respect to the normal line, and a P<+> type region 14 is formed. Accordingly, the reading gate electrode side becomes high concentration, the stopper side becomes low concentration, signal charge stored at an N<-> type region 5 is gathered to an N-type region 7 of the reading gate side of deep potential. When the signal charge is transferred to the stopper 4, all the charge can be transferred. Thus, no after image is generated, and a high saturated voltage value is obtained.
