Title: Common information processing system and work station
Inventor: ISHIZAKI TAKESHI
IPC: G09G5/14
Filed: 1990-11-21
Abstract: PURPOSE:To utilize this common information processing system for electronic interaction without changing an application program by changing a window library module and extending a function. CONSTITUTION:An event acquiring module accessed from a client program 22 temporarily transfers an event received from a window server 21 to an interaction control program, which executes processing necessary for co-operative work and transfers the event to the event acquiring module. When the client program 22 having accessed and event acquiring module is to be driven in a local mode, the module directly transfers the event received from the server 21 to the program 22. Thus the client program 22 can be optionally applied in an electronic interactive environment.

IPC: G03G15/05
Filed: 1988-12-13
Abstract: PURPOSE: To prevent a modulation electrode from becoming corrosive and thereby prolong the life by making a protective surface layer of each of modulation electrodes sufficiently conductive so as to be chemically neutral to corona effluents and also dissipate ionic charges accumulated on the surface to a thin film conductive base layer. CONSTITUTION: A modulation electrode is sufficiently conductive across the entire length of the electrode so that it is not adversely affected and at the same time, is chemically neutral to a corrosive corona effluent. In addition, the modulation electrode has a surface layer which is resistive so that ionic charges flow down to an electrode below passing through a thin film. That is, the modulation electrode comprises numerous thin layers supported on a substrate 42, and the first layer serves as a conductive electrode 58, on which a modulation electrode 60, a TFT contact point and a resistor are patterned after vapor-depositing an n<+> silicone thin film layer. On the surface of the n<+> modulation electrode which is exposed, a thin and insulating intrinsic silicon dioxide layer 62 is caused to grow. An n<+> base layer 60 is conductive adequately in a direction along a modulation electrode finger, so that a modulation current runs, not adversely affected within the range of time when it is actually required for a printer.

Title: Agitation impeller
Inventor: KATO KOICHI
IPC: B01F27/91
Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To provide an impeller having a simple structure and high agitation efficiency by forming the front end of each of the blade units with which the boss is provided so as to allow them to project and extend from the boss, into a shape extending in both the forward and rotational directions, in the impeller consisting of a boss and blade units. SOLUTION: This impeller 1 consists of a boss 3 and three blade units 2 each having a single plate blade, etc. In each of the blade units 2, each of the front edge 2a and the rear edge 2b of the blade are formed into a linear shape and also, the front end of the blade extends in both the forward and rotational directions. Also, each of the blade units 2 is fixed to the boss 3 with a screw 2c so as to have an attack angle to the rotational direction.  Thus, since each of the blade units 2 extends both forward and rotational directions, the streamlines of a fluid in contact with a blade surface are comparatively long and flow along the blade surface and at this time, since the fluid stream first passes the front end of the blade, a pressure difference across the whole blade back surface in the direction toward the base of the blade from its front end is generated to reduce the vortex formation. Accordingly, the separation of the fluid stream from this blade surface is hardly caused to improve the agitation efficiency of the impeller.

Title: Alignment correction system
Inventor: HIRASAWA YUTAKA
IPC: G06F9/44
Filed: 1986-12-26
Abstract: PURPOSE:To attain program conversion irrespective of the system of a structure by means of a common routine by converting the structure based on alignment information of the structure. CONSTITUTION:Since the number of bytes differ in an integer, a real number, character data, and the like on storing data on the structure, an idle space occurs in a memory. Since the directions of the idle space differ in respective computers, the structure also needs to be converted at the time of program conversion. Consequently, an alignment information storage part 13 is provided, and '1' is assigned as to the significant byte of the structure, and '0' is to the byte inserted for alignment. The byte length of the structure stored in a structure storage part for correction 11 is stored in a register part 14, and alignment information is in the alignment information storage part 13. The byte whose alignment information is '0' is ignored, and only the significant byte is fetched, converted into the structure of a new system, and stored in a structure storage part 12 after it is corrected.

The wire rod fed by the feed process is formed into a bending part of one winding by a support roller 16 and a forming roller 17 operated by an actuator 18. Simultaneously with this, a curvature part having different curvature by one winding portion of a floret pattern is formed. The forming roller 17 is operated on the bending process, so that forming of the curvature part is started by the signal of a one rotation detector 58 at every rotation of a rotary plate 26, and motion after that is controlled by a control circuit 20A. Wire rod 9A formed by bending falls in order so as to be wound with a winding drum 22 on a base body 1.

SOLUTION: When a louver 4 is pushed into a frame 2, the clip 9 of the louver 4 abuts, at the front inclining side 11A thereof, against the protrusion 3 of the frame 2 at the rear inclining face 3B thereof. When the engaging part 11 of the clip 9 passes through the protrusion 3 of the frame 2, the clip 9 is recovered resiliently. Consequently, the clip 9 abuts against the front inclining face 11A of the protrusion 3 and enters into a state engaged with the protrusion 3. When the louver 4 is removed, it is taken out from the inside of the frame 2. The clip 9 of the louver 4 abuts, at the rear inclining side 11B thereof, against the protrusion 3 of the frame 2 at the front inclining face 11A to push down the engaging part 11 of the clip 9. When the engaging part 11 of the clip 9 passes through the protrusion 3 of the frame 2, the clip 9 is recovered resiliently and the louver 4 can be taken out from the frame 2.

Title: Refrigerant distributor
Inventor: YOSHITSUBAKI AKIFUMI
IPC: F25B41/00
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To distribute refrigerant uniformly by a method wherein a refrigerant distributor includes a refrigerant inlet pipe, a bag-like collision wall where refrigerant spouted from the inlet pipe collides, and two refrigerant outlet pipes that are formed in the periphery of the collision wall and have openings that are surrounded by the shells and located symmetrically with respect to the axis of the refrigerant inlet pipe. SOLUTION: A refrigerant distributor main body 1 includes a refrigerant inlet pipe 2, a refrigerant outlet pipe 3 connected to the refrigerant inlet pip 2. and a bag-like collision walls 4. When the influent direction of the influent refrigerant does not meet the direction of the axis of the refrigerant distributor main body 1 due to a scatter in connection accuracy of the refrigerant inlet pipe 2 and a velocity vector parallel with the collision wall 4 is produced, the refrigerant is prevented from being unevenly distributed because the influent refrigerant flows into the bag-like collision wall 4 and is agitated. Therefore, a uniform distribution can be attained without influences of a scatter in connection accuracy of the inlet pipe and deflecting flow of influent refrigerant.
