Title: Cutting blade-changing finger cutter and substituting blade for finger cutter
Inventor: TSUCHIYA ATSUSHI
IPC: B27F1/16
Filed: 1993-05-25
Abstract: PURPOSE:To eliminate the slippage of substituting blades by a method wherein a cutter main body is constituted by laminating a plurality of unit boards, in each of which blade groove is formed at two or more positions and, at the same time, projected parts are provided adjacent in the direction of rotation to the specified blade grooves. CONSTITUTION:Blade grooves 2A-2D are formed at the intervals of 90 deg. on the outer peripheral part of each unit board 1. The cutting flank 1e of each of the blade grooves 2A-2C follows to the periphery 1f. At the blade body abutting surface 1b, a projected part 1g, the length of which is half as much as the interval between the blade grooves, is formed so as to support the cutting force applied to the finger part of each substituting blade. The projected part 1g is formed at the blade grooves 2A and 2C, while no projected part is formed at the blade grooves 2B and 2D, because no cutting blade is provided at the blade grooves 2B and 2D. After ten unit boards are laminated to one another under the state that the projected parts 1g of the unit board 1 are staggered by 90 deg., pins inserted in pin holes 1h so as to compose a set of blade bodies. Accordingly, as the cutting force of a change blade mounted to the blade grooves 2A and 2C is supported by the projected parts 1g, no slippage of the substituting blade occurs.

Title: Semiconductor optical modulator and semiconductor optical element
Inventor: ISHIZAKA MASASHIGE
IPC: H01S5/12
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To correct the deviation of a cross point to obtain a satisfactory optical modulation waveform by devising the structure of an electric field absorption optical modulator to change a nonlinear extinction characteristic to a linear characteristic. SOLUTION: A layer structure is provided where an n-type semiconductor buffer layer 102, a semiconductor light absorption layer 103, and a p-type semiconductor clad layer 105 are successively laminated on a semiconductor substrate 101, and an n-type electric field relaxing layer 104 is interposed between the light absorption layer 103 and the n-type clad layer 105. The n-type density and the thickness of the n-type electric field relaxing layer 104 are adjusted to be able to freely control the electric field intensity change in the light absorption layer to an external voltage. Since the external voltage is relaxed in the n-type electric field relaxing layer 104 at the time of applying a low voltage through electrodes 107 and 108, the intensity of the electric field applied to the light absorption layer 103 has a nonlinear behavior for the external voltage.  This nonlinear electric field intensity change corrects the nonlinear absorption change for the applied electric field of the light absorption layer 104, and thus, cross point reduction of an optical output eye pattern is suppressed to obtain a satisfactory modulation optical output waveform.

IPC: H01L21/205
Filed: 1991-06-19
Abstract: PURPOSE:To enhance the stability and the yield by a method wherein the title compound semiconductor single crystal epitaxial substrate is composed of four element mixed crystal in specific composition and almost equal composition ratios of III group elements in a well layer and a barreir layer. CONSTITUTION:Supposing that x3=0.29, y3=0.63 in the composition of a barrier layer 5 represented by an expression, the composition ratios x of III group elements and the composition ratios y of V group elements in the well layer 4 having the compressive strain of about 1% are respectively to be x2=x3=0.29, y2=0.85 while not only the composition ratios x of the III group elements are equalized but also the difference between the well layer 4 and the barrier layer 5 in the composition ratios y of the V group elements is lessened. On the other hand, the mixed crystallization i.e., the cause of the mutual diffusion of the constituent elements between the well layer 4 and the barrier layer 5 can be attributed to the difference in the composition ratios making the mixed crystallization hardly occur thereby enabling the yield of laser element and the longtime reliability to be enhanced. Furtheremore, the multiquantum well structure can be easily grown by a simple method due to the equalized composition ratios x of III group elements in the well layer 4 and the barrier layer 5.

Abstract: PURPOSE:To prevent the influence of an excessively high white level in picture signals caused by abnormal reflection to the gain of an automatic gain controlling means by fixing the gain of the means while it is highly expected that abnormal reflected light from the leading edge of an original is received by an image sensor. CONSTITUTION:The positional relations between the leading and tailing edges of an original 11 and an original reading position P are detected (original position detecting means) based on the detecting signal of an original sensor 5 and the feeding quantity of the original. A gain fixation control circuit 6 operates based on the output of the original position detecting means. A narrow control zone W is set on both sides of the reading position P, and while the leading and tailing edges of the original 11 pass through the zone W, the control signal C given from the circuit 6 to the ABC circuit 3 is turned off. Then the circuit 3 is fixed to the said gain and automatic gain control is restarted when the signal C is turned on. Therefore, influences of abnormal reflection from the leading and tailing edges of the original can be eliminated and deterioration of the picture quality can be prevented.

Abstract: PURPOSE:To record, display, hold, and rewrite information directly almost without any electric power by forming electrodes in stripes on the surface of light transmissive ceramic which has the Kerr effect of voltage control, coating the electrodes with an insulator, and giving a potential difference to the surface of the light transmissive ceramic by using a head for voltage application. CONSTITUTION:Counter electrodes are formed on a PLZT substrate 1 and a voltage is applied between the electrodes to cause the birefringence of the PLZT substrate. For the purpose, a polarizing film is arranged on both surface of the PLZT substrates and then a difference in brightness is generated between the part where the birefringence is caused and other parts, thus making a display. Then when a switch is opened while the voltage is applied to the PLZT substrate 1, the birefringence of the PLZT substrate 1 is held and a storage state is entered. The state is reset by short-circuiting the substrates. Thus, the characteristics of a PLZT element is utilized, the voltage is applied to electrodes for voltage application optionally while the striped electrodes 2 are held at 0V, and the head is scanned by a head scan driving part to cause the display state and storage state.
