Title: Automatic lubricator for bearing
Inventor: URUFU BENGERAA
IPC: F16C33/66
Filed: 1988-06-21
Abstract: PURPOSE: To retain a uniform temperature within a bearing housing by controlling a valve body as to stop feeding grease to the bearing housing when a shape memory metal spring stretches sensing the temperature of the bearing housing. CONSTITUTION: Under normal operating condition within the bearing housing, when a shape memory metal spring 5 is in a compressed state, a valve opens and springs 5, 6 operate so that grease can be uniformly supplied inside the bearing housing. When the temperature rises with grease increasing in amount inside of the bearing housing, for example, the established temperature exceeds 60 deg.C, the stretched spring 5 causes the valve body 4 to go up within the valve housing 7 to close an opening 8.

Title: Method for etching one surface of semiconductor wafer
Inventor: ABE KOZO
IPC: H01L21/306
Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To uniformly etch only one surface of a semiconductor wafer over the entire area by immersing the surface in an etchant while the wafer is held by suction with a vacuum chuck with the other surface above the etchant. SOLUTION: When a vacuum pump 10 is started after a stop valve 8 is opened, the pump 10 evacuates air from each suction hole 4 and a vacuum chuck 2 holds a wafer 1 by suction. Then one surface of the wafer 1 is etched by immersing the surface in an etchant 12 contained in an etching container 13 by holding the chuck 2 with a handle 3. After the surface is etched to a prescribed state, the wafer 1 is taken out from the container 13 by means of the handle 3 and the etched surface is immersed in a cleaning solution in the same way. After cleaning the surface, the surface is dried. Then the valve 8 is closed and the wafer 1 is taken out by opening a stop valve 9 and starting a compressed air supplying machine 11.  Therefore, one surface of the wafer 1 can be etched uniformly over the entire area and the one surface etching work can be performed easily and quickly without giving any damage to an oxide film formed on the other surface of the wafer held by the chuck 2 by suction.

Title: Target program transfer system between computer system
Inventor: GOTO YOICHI
IPC: G06F15/16
Filed: 1989-06-13
Abstract: PURPOSE:To connect the systems by a non-transparent mode line so that a target program can be transferred by decomposing the target program into constitution data, converting it in accordance with conversion rule information and transmitting it, bringing received data to reverse conversion to reproduce the target program, and storing this target program. CONSTITUTION:A conversion processing means 12 divides a target program into one digit each of hexadecimal data from a transmitting side storage means 11, and there after, converts it in accordance with conversion rule information stored in a conversion rule table 13 and delivers it to a transmitting means 14. The transmitting means 14 transmits the delivered data by using a communication line 3 of a non-transparent mode procedure. A receiving side computer system 2 receives this data by a receiving means 24, a reverse conversion processing means 22 returns it to the original target program in accordance with reverse conversion rule information stored in a reverse conversion rule table 23, and a receiving side storage means 21 stores the delivered target program. The operation is repeated until the data obtained by dividing the target program into units of one digit of a hexadecimal number is gone. In such a way, the target program can be transferred easily in a short time by using a non- transparent mode line.

Title: Water-permeable concrete block for pavement
Inventor: IKEDA AKIRA
IPC: E01C5/06
Filed: 1992-06-11
Abstract: PURPOSE:To permit downwardly flowing rain water to be stored dispersedly in each place of blocks by a method in which the notches of water-permeable concrete blocks having water-impermeable parts are set orthogonally to the sloped direction of the ground. CONSTITUTION:A set of four water-permeable concrete blocks 1 having notches 9 packed with a cushion material 10 mixed with cement to form a water- impermeable part are arranged in such a way that the notches 9 form a square- shape (planar view) by orthogonally crossing one side of the notch 9 with the sloped direction of the ground. Rain water 13 is once housed in the space 14 surrounded by the surface of the ground 4 and the cushion-sand 10 and flows down through the blocks 1 from the space 14. The rain water 13 flowing along the slope is dispersed into each place and stored. The amount of the water flowing down to the lower final point of the sloped ground can thus be lessened.

Title: Antenna system
Inventor: KOSUKEGAWA KAZUO
IPC: H01Q19/19
Filed: 1985-07-09
Abstract: PURPOSE:To improve the wide angle directivity by providing a sub reflecting mirror supported by plural supports corresponding to a main reflecting mirror and forming a shadow image as a single strip shadow while using an optional single line as a base line at each support so as to suppress the caused sub lobe level. CONSTITUTION:The sub reflecting mirror 2 is arranged corresponding to a main reflecting mirror 1 and the sub reflecting mirror 2 is supported by supports 3-1-3-3. Not a single straight line support but a waving support is used for each support and the support 3-1 is formed corresponding to, e.g., a waving base line 101. Since the shape of equivalent aperture face of the supports 3-1-3-3 formed waving in this way shows waving form in the wide angle directivity within a plane perpendicular to a plane including the supports 3-1-3-3 and their antenna axes, the directivity of the equivalent aperture is scattered in terms of the angle and not deteriorated.

Title: Developing device
Inventor: KUBO TSUTOMU
IPC: G03G15/08
Filed: 1983-08-23
Abstract: PURPOSE:To generate triboelectricity thoroughly in a developer and to obtain a sharp image without fogging by coating an electric charge member on the surface of a carrier body or a member for forming a developer layer. CONSTITUTION:An electric charge member 6 is coated on the surface 3a of a member 3 for forming a developer layer which faces a carrier body 4 and the surface of the body 4. When the body 4 is rotated, a developer 2 is charged by the friction between the surface of the carrier body and the member 3, but the member 6 is coated on the surface of the carrier body and the surface 3a facing the member 3 and therefore the developer 2 is thoroughly charged by the friction to have enough electric charge. The member 6 is selected by taking the triboelectrification series with the developer 2 into consideration. Styrene (acryl, polyester, epoxy, polyamide, fluorine, silicone, polycarbonate, etc.) resins, etc. are utilized for said member. A styrene/methyl methacrylate/vinyltriethoxysilane copolymer is most preferred if the developer is negatively charged.
