Title: Four way change-over valve
Inventor: NAGAI MAKOTO
IPC: F16K11/10
Filed: 1981-04-30
Abstract: PURPOSE:To provide a four way change-over valve with simple construction and few number of parts by inserting a valve rod combined with a check valve mechanism into a valve body utilizing an universal piping used for refrigerating cycle piping and using such two valve rods. CONSTITUTION:A mandrel 2a provided at both ends with piston mechanisms 16a, 16b is inserted in a first valve pipe 1a. Valves 4a, 4b provided on the mandrel 2a are seated alternatively on valve seats 3a, 3b fixed to the valve pipe by the vertical movement of the mandrel. The respective valves 4a, 4b are provided with through holes (not shown). While similar mechanism is incorporated in a second valve pipe 1b, the positional relationship between the valve and valve seat is reversed. When current is supplied to a pilot valve 11, high pressure refrigerant flows from a piping 6 leading to a compressor as shown by the solid line so that a circuit from a piping 7 through a condenser and evaporator to a piping 8 and then from a piping 9 back to the compressor is formed. When the current to the pilot valve is stopped, the refrigerant flows as shown by the dotted line.

Abstract: PURPOSE: To reduce damage of hull by cutting ice at below the surface of water with a revolving disc saw by enabling the accommodation an arm thereof provided with a revolving edge for ice cutting at its tip, having a base plate pivotted to the bow with a cylinder.  
     CONSTITUTION: An arm 3 provided with a revolving disc saw 2 at a tip being pivotted at a bow with a base plate which can be accommodated in a bow space by means of a cylinder 4. For ice breaking, ice is cut by the revolving saw after the revolving saw is positioned underneath an ice plate 6 by adjusting the arm 3 with the cylinder 4. Ice breaking is performed by either bumping or stranding the hull against or on the ice plate of after prepg. cut grooves at the lower part thereof. Since grooves are formed prior to the breaking of ice, the breaking work is performed easily and securely with a least damage to the hull.

Title: Storage tank structure
Inventor: MIYOSHI YOICHI
IPC: F17C13/00
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To make an oil surface level in which a suction filter starts sucking oil as low as possible, and increase the amount of oil effectively usable. SOLUTION: A suction filter 2 is covered with a filter cover 4, and the inside space of the filter cover 4 is communicated with the outside of a tank main body 1 through a ventilation pipe 5. When oil is supplied from an oil supply part 8, air within the filter cover 4 is expelled through the ventilation pipe 5. When after a cap 9 and a seal bolt 7 are fit and the oil surface level falls, the oil surface level within the filter cover 4 and the pipe 5 becomes always higher than that within the tank main body 1. If the oil surface level within the tank main body 1 does not reach an opening part 6, the suction filter 2 does not suck air.

Filed: 1991-03-28
Abstract: PURPOSE:To shorten the overall tact time in a robot job where the position error of a work is detected to a teaching point and then corrected by shortening the time needed for detection and correction of the work position error. CONSTITUTION:The P1-1-P13-1 are taught to the works 7 and 8, and the error is detected between the work 7 set at P2-1 and P5-1 and a teaching point. An instruction is carried out so that the detected error is written into a designated memory position, and such instructions are shown after the P2-1 and P5-1 so as to correct the teaching position with the error value. Then an instruction is shown to read the error of the work 7 produced between P10-1 and P2-1 and to correct this error. If both works 7 and 8 are set at the positions shown by the broken lines, the error of the work 7 is corrected at the P10-1. As a result, the correction is possible at all positions just with detection of the error between the P2-1 and P5-1. Then the robot working time is extremely reduced.

IPC: B41J2/21
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To provide a color imaging apparatus in which even a plain paper can be recorded by multi level halftoning for reducing inter-color blur while keeping the gray level. SOLUTION: A record control section 18 can represent gradation by overlapping up to two ink drops in recording through use of an ink jet head 20. K (black) ink is slow dry type and other color inks are quick dry type. An N-state converting section 12 converts an image data into a ternary data. A processing pixel extracting section 14 makes a decision whether a color image region exists in a specified region or not for the pixels in black image region based on the logical operation results of ternary 2 bits and extracts pixels in a region adjacent to the color image region. According this extraction result, each region is divided by a region dividing section. A converting section 16 converts the adjacent region such that the number of K ink drops decreases for the entire adjacent region thus reducing inter-color blur.

Filed: 1993-03-24
Abstract: PURPOSE: To hold a machine tool in an accurate straight condition along its running track by providing a means measuring a position of a movable base for a reference line fixed on a bed and a compensation means controllably moving the machine tool relative to the movable base in accordance with a deviation from the straight movement of the movable base. CONSTITUTION: An RID 38 monitors a position of a reference wire 28 to generate a signal read and translated by an electronic signal processing device 46. This signal is sent to a differential amplifier 78 of a position control block 68. If the signal received from the electronic signal processing device 46 differs from a predetermined initial signal meaning a straight position expressed as a desired part side face position command, the position control block 68 generates a position command in which straightness is compensated. This command is compared with actual positions of a machine tool 48 and a grinding wheel 52 through a lead wire 82. When the compensation is necessary, a position error speed command is sent to a servo control block 72 to adjust a position of the machine tool.
