Title: Operating circuit for hydraulic actuator
Inventor: ITOU DAIJIROU
IPC: F15B11/16
Filed: 1980-02-21
Abstract: PURPOSE: To provide a low-priced unit and symplify its operation by connecting a plurality of actuators to a direction shift valve and by installing in each connection circuit a pilot check valve which is opened by a pilot pressure from each open/close change-over valve.  
     CONSTITUTION: A plurality of actuators 1a, 1b and 1c are connected to a direction shift valve 2. A pilot check valve 4 is installed in each connection circuit respectively. Open/close change-over valves 5a, 5b and 5c are provided between the pilot  circuits of the pilot check valves 4 and a hydraulic power source 3. As a plurality of  actuators 1a, 1b and 1c can be controlled by one direction shift valve and open/close change-over valves through this construction, the mumber of direction shift valves where a large quantity of oil flows can be reduced. This makes the unit low-priced and reduces the number of levers as well, symplifying the operation.

Title: Optical head
Inventor: SASAKI YOSHINORI
IPC: G11B11/10
Filed: 1987-01-29
Abstract: PURPOSE:To attain the miniaturization of an optical head by detecting a magneto- optical change of a recording medium depending on the difference from the intensity of two beams whose intensity is varied depending on the polarized state and using a beam having no intensity change due to the polarized light so as to detect an error signal for the servo control and the reflectance change of the recording medium. CONSTITUTION:A Wollaston prism 33 is arranged in the optical path of a reflected light or a transmitted light to separate the reflected light or the transmitted light into two beams 700, 900 whose intensity is changed depending on the polarized state and into one beam 800 whose light intensity is unchanged due to polarization A photodetector 34 with elements a-b receiving the three beams separately respectively arranged on one and same face is provided and the magneto-optical change in the recording medium is detected depending on the difference of intensity of the two beams 700, 900 whose intensity is changed due to the polarized light state and the reflectance change of the recording medium and the error signal for the servo control are detected by using the beam 800 whose intensity is not changed due to the polarization. That is, the head is constituted by one optical system. Thus, the miniaturization of the optical head is attained.

Title: Vibration isolator of reciprocating engine
Inventor: DOBASHI YUTAKA
IPC: F16F15/02
Filed: 1987-01-30
Abstract: PURPOSE:To make it possible to install a reciprocating machine having a reciprocating motion element even on a high-storied floor, by providing an anti-motion element, which moves in the reverse direction with respect to a reciprocating element, to a vibration isolator of the reciprocating machine. CONSTITUTION:When a high-speed crank press 11 operates in order to move a slide 15 up and down, vibration occurs because of this operation. However, since a weight 18 is moved up and down in the reverse direction with respect to the slide 15 via a chain 17, the vibration energy accompanying the vertical motion of the slide 15 and that accompanying the vertical motion of the weight 18 cancel each other, the vibration can be prevented. In addition, since the main body 14 of the high-speed crank press 11 is installed on a fixed floor 12 via an air spring 13, vibration isolation by the air spring 13 is also carried out. As a result, installation of the vibration isolator on a high-storied floor such as the second or third floor, which has been considered impossible so far, becomes possible.

Title: Production of lactone-modified diol
Inventor: ISOBE TOMOHISA
IPC: C08G63/08
Filed: 1986-02-03
Abstract: PURPOSE:To produce a lactone-modified diol which can give a urethane resin which by itself can eixibit weathering resistance, by reacting 2,2,6,6- tetramethyl-4-hydroxypiperidine with a lactone. CONSTITUTION:1mol of 2,2,6,6-tetramethyl-4-hydroxypiperidine of formula I is reacted with 2-15mol of a 4-8C lactone to obtain a lactone-modified diol of formula II. When the amount of the lactone added is below 2mol, the flexibility inherent in lactone chains cannot be fully imparted to the formed lactone adduct. When this amount is above 15mol, the MW is excessively large and the viscosity is high, which makes handling in urethane formation difficult. epsilon-Caprolactone is a particularly desirable lactone in many respects.

IPC: H04N1/46
Filed: 1988-01-30
Abstract: PURPOSE:To obtain a hard copy with high picture quality and fidelity to color reproduction by applying color ghost correction only as to an area discriminated to be a binary picture by an area discrimination means. CONSTITUTION:A digital picture signal subject to shading correction is discriminated as to whether its area is a binary picture area or a contrast picture area by area discrimination circuits 13-15, the result is fed to an OR circuit 20. The output of the OR circuit 20 is fed to a color ghost correction circuit 13 as an area discrimination signal via a memory 21. That is, when any of the area discrimination circuits 13-15 discriminates it as a binary picture, the output applies color ghost correction. proper color ghost correction is applied to a picture data before multi-value processing by discriminating the picture as to whether it is the binary picture or the contrast picture and applying color ghost correction to the binary picture only in this way. Thus, a hard copy with high picture quality and fidelity to color reproduction is obtained with simple circuit constitution.

Filed: 1982-02-13
Abstract: PURPOSE:To permit almost no influence of generation of distortion at carburization hardening to machining accuracy and generate a crowning effect, by integrally forming a flange to the central part of an external wall in the outer cylinder of a spline bearing. CONSTITUTION:A limitlessly sliding ball spline is constituted by a spline bearing B and spline shaft S supported by balls 3 built in the bearing B to perform linear motion in the axial direction and rotary motion of torque transmission respectively in a single or combined state, in which a flange 2 is integrally formed to the almost central part of an external wall in an outer cylinder 1 of the bearing B. That is, even if the flange 2 is formed to the external wall of the outer cylinder 1 before carburization hardening, generation of distortion due to the carburization hardening is not almost influenced to machining accuracy, on the contrary, the distortion due to the carburization causes a crowning effect, and turning work for forming the flange before carburization can be performed when the outer cylinder with the flange is manufactured.

Abstract: PURPOSE:To cut cost by adopting a vertical shaft pump equipped with a vacuum breakage device which has a vane wheel arranged at the position higher than the min. water level which is characteristic for the pump, as a part of a plurality of vertical shaft pumps. CONSTITUTION:In the ordinary vertical shaft pumps 201 and 301, each position of the suction bell-mouths 214 and 314 is set higher than the min. lowest water level LWL1 of an air suction type vertical shaft pump 101.
