Title: Optical waveguide type displacement sensor
Inventor: SATO KENJI
IPC: G01B9/02
Filed: 1994-02-10
Abstract: PURPOSE:To provide an optical waveguide type displacement sensor which does not require any reflection preventing film, does not produce much noise, and can be reduced in size and cost. CONSTITUTION:An optical waveguide substrate A is constituted by forming optical waveguides 2 and 3 on an electrooptic crystal substrate 1 and a directional coupler 4 at the adjoining part of the waveguides 2 and 3. The end faces 1c and 1d of the substrate 1 and end faces 6a and 6b of a SELFOC lens 6 are respectively cut diagonally to their length directions. Since the end faces 1d, 6a, and 6b are oblique to the advancing direction of light, the quantity of reflected light which return to the coupler 4 as noise is reduced. The coupler 4 spectrally splits laser light L1 and output interference light L3 by causing measuring light returning from an object to be measured and reference light returning from a reflection mirror 5 to interfere with each other.

The output voltage of the terminal B is set to a value lower than the necessary voltage, and is superposed through the element 61. Thus, the switching power of the element 61 can be reduced to reduce the size of the circuit, thereby decreasing the cost.

Abstract: PURPOSE:To prevent the mixing of colors in multicolor printing to obtain clear printing by a method in which a guider to hold a printing ribbon is moved to the straight line direction crossing the moving direction of a carrier, and a ribbon roller is provided to the guider. CONSTITUTION:A guider 19 to guide a part of a printing ribbon 8 slidably along the moving direction of a carrier 2 is provided movably toward straight line direction crossing the moving direction of the carrier 2 connectly to a ribbon switching mechanism 26. Plural ribbon rollers 20 to define the path of the ribbon 8 are provided to the guider 19 in a turnable manner. The ribbon 8 is always faced a printing section 1 in parallel and the guider 19 is moved to the switching direction. Since the path of the ribbon 8 is defined by the rollers 20, however, the running resistance of the ribbon 8 is smaller, and therefore, the ribbon 8 quickly follows the switching action of the guider 19 to prevent the occurrence of wrinkle in the ribbon 8. Since the ribbon 8 can be run smoothly, the mixing of colors in multicolor printing can be prevented.

Title: Synthesized picture output device
Inventor: KAMO YASUSHI
IPC: H04N1/387
Filed: 1992-02-03
Abstract: PURPOSE:To eliminate the need for a trial print by limiting an intermediate tone density of a character pattern within a prescribed range based on a detected highest density to automate the adjustment of the intermediate tone density. CONSTITUTION:A digital comparator 212 compares a value latched in a latch 211 and a density of gradation picture data applied from a picture quality processing circuit 205. When the density of input data is larger, the latch 211 revises the latched value and finally latches a highest density value. Furthermore, data are in advance written to each address of a ROM 315 so as to act like a conversion table, a detected highest density is inputted to its address terminal, a value multiplied with a prescribed coefficient is outputted and the value is converted into an intermediate density of additional information. Since the coefficient is variable, the additional information density is automatically decided based on the highest density, the accumulated frequency by density or a background density. Thus, the density is limited to the intermediate density within a range between predetermined upper and lower limits, the adjustment is automated and no trial print is required.

IPC: F16H61/12
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To properly control the engagement and disengagement of friction clutch along with the shifting and prevent double engagement. SOLUTION: The friction clutch CL1, CL2, CL3 may double engage when all engaged. The receiving surface ratio of the port 21, 22, 23 is set to be equal to the ratio of torque value produced by control pressure per unit applied to respective friction clutch. When a proper output pressure from the three way solenoid valve 1, 2, 3 is applied to the friction clutch CL1, CL2, CL3, a fail save valve 20 is balanced at the position as shown in figure. If at least one of the control hydraulic pressure applied to the friction clutch CL1, CL2, CL3 is increased beyond a specified pressure value, the fail-safe valve 20 moves to left to prevent the application of abnormal pressure. Therefore, the sum of engaging torque of each of respective friction clutches is limited to a fixed value so that the double engagement of the friction clutches CL1, CL2, CL3 will be avoided.
