Title: Sub-valve for auxiliary hydraulic pressure
Inventor: YONEYAMA FUMIO
IPC: F15B11/08
Filed: 1991-04-05
Abstract: PURPOSE:To prevent reduction in the actuation responsiveness of a control valve which is actuated by a pilot hydraulic pressure which can be obtained without using a subpump. CONSTITUTION:A sub-valve 10 is comprised of by arranging a sequence valve 20 in a main oil passage, and arranging a reducing valve 30 in a sub oil passage. The reducing valve 30 opens the sub oil passage when the oil pressure Pp in the sub oil passage on the downstream side is below the specified hydraulic pressure, while it closes the sub oil passage when the Pp is over the specified value. When the pressure Pp exceeds the specified value by a certain amount, the pressure Pp in the sub oil passage works on the sequence valve 20 which communicates the downstream side of the sub oil passage with a drain in such a direction to close the sequence valve, while the pressure Pp opens the sequence valve when the pressure difference DELTAP between the pressure Pp in the sub oil passage on the downstream side and the pressure P1 in the main oil passage on the upstream side reaches the second specified value, and the working oil is supplied from a hydraulic power source to the main hydraulic pressure port through the main oil passage.

Title: Sand casting mold
Inventor: SATO MITSUYOSHI
IPC: B22C9/02
Filed: 1994-04-14
Abstract: PURPOSE:To easily produce thin regardless of casting materials and to provide the sand casting mold having excellent thermal impact resistance by incorporating metallic chips at specific sizes and ratios into molding sand formed by kneading resins of an org. system in a sandy form. CONSTITUTION:This sand casting mold is used for casting to be executed by immersing the sand mold into, for example, molten metal and sticking the molten metal to the outer periphery thereof. The sand mold receives the heat quantity meeting the length of the immersion time and the metallic chips 3 having 5 to 20mm length, 0.2 to 0.6mm outside diameter at 1.4 to 3.0wt.% ratio to the molding sand 2 forming by kneading the resins of the org. system to sand grains. Crack is, therefore, prevented by the largeness of the heat capacity. The solidification of the molten metal progresses in a short period of time in a coating layer 4 consisting essentially of zirconia and iron powder and, therefore, the thin castings are stably formed.

Abstract: PURPOSE:To obtain a laser element which has a variable phase shifting amount, suppresses concentration of a light to a phase shifter and obtain a flat light distribution in a resonator by etching at least part of a waveguide layer formed with a periodic uneven structure to a desired thickness while controlling the shape of the uneven structure. CONSTITUTION:After a GaInAsP active layer 12 and a waveguide layer 13 are sequentially crystalline-grown on an InP substrate 11 a diffraction grating is formed by a two-beam interference exposure method using a laser. Then, only a phase shifting region near the center of a resonator is exposed by using photoresist 18. Thereafter, it is etched to a thickness of obtaining an equivalent refractive index of a desired active layer by using a sulfuric acid etchant. In this case, since the thickness of the layer 13 weakens coupling of a light in a thin region, the uneven part of the grating is reduced by using the etchant having weak etching anisotropy. Subsequently, a clad layer 14, a contact layer 15 are sequentially crystalline-grown, an electrode 16 is deposited, and AR films are further deposited on both end faces to form an element.

Title: Man-machine interface device

Filed: 1989-04-21
Abstract: PURPOSE:To execute a setting with the operation of a rotary encoder even when an allocation with an operation menu is not executed by coupling pointer data stored in a RAM when the allocation of the rotary encoder is not executed to the program of the operation menu to be set. CONSTITUTION:When the new menu is selected, a function key designated according to the menu to the program itself of the menu and the pointer of the rotary encoder are read from a ROM 12 and coupled. When the rotary encoder is not allocated in the new menu there, the pointer data stored in a RAM 13 are coupled to the program at such a time. Consequently, the design of the menu is executed in one picture unit to contain the function key and rotary encoder in the same way as a conventional way, but the function key and rotary encoder are cut off at the time of executing the operation and only the rotary encoder is dynamically coupled. Thus, even when the allocation with the operation menu is not executed, the setting by the operation of the rotary encoder can be executed.

Filed: 1978-08-24
Abstract: PURPOSE: To reduce the influence of high-degree space frequency components without increasing the number of photoelectric elements by making photoelectric elements into a specific form in the displacement detection unit of an optical image.  
     CONSTITUTION: Element width S in the arrangement direction of photoelectric elements P which constitute photoelectric element array 2 is made equal for every element, and one period d of space frequency components to be extracted is defined as d=4S. Photoelectric elements P are inclined for the arrangement direction of them and go in one adjacent elements. That is, in respect to photoelectric elements P, the boundary line of adjacent photoelectric elements is not parallel with the line vertical to the arrangement direction of elements and is inclined for the vertical line. The photoelectric element form inclined in this manner reduces the influence of three or more-degree space frequency components, so that the photoelectric synthesized output vector can be prevented from being affected by high-degree frequency components when an optical image is projected onto the photoelectric element array.
