IPC: B29C65/70
Filed: 1990-11-08
Abstract: PURPOSE:To manufacture a laminated rubber plug inexpensively by laminating a synthetic film larger than the diameter of a rubber plug foot section and an unvulcanized rubber sheet, pressure-heating the laminate in a mold, covering the foot section with the unvulcanized rubber sheet with a hole formed separately, pressure-heating and molding, and then cutting-removing flashes. CONSTITUTION:A mold B for primary molding is a mold of the shape slightly deeper than the shape of a foot section of a final product, and a mold A is a mold having the depth slightly less than the depth of a point face section of the final product. A laminate consisting of a synthetic resin film 1 and an unvulcanized rubber sheet 2 is placed between said molds, heated under the pressure and vulcanized. Thus a primary molded product with a laminate having flashes is manufactured. The foot section of the molded product is covered with an elastomer sheet 3 having a hole of same diameter as that of a root of a rubber plug foot section manufactured separately. The molded product is pressure heated between molds C and D fit for the shape of the final product to manufacture a secondarily formed product. The formed product is released out of the mold, and flashes on the peripheral sections are removed by punching to manufactured the final product.

Title: Steering device for working vehicle
Inventor: YUKI NOBUO
IPC: B62D11/10
Filed: 1994-12-07
Abstract: PURPOSE: To improve steering operation performance by adopting a pair of planetary transmission mechanisms and changing the rotating speed of one of three structural elements in mutually righ-and-left opposite operation so that a turning radius can be freely set. CONSTITUTION: When a steering lever 22 is in a neutral position, right and left planetary transmission mechanisms 9, 9 are at the same speed to drive right and left drive axles 8R, 8L at an equal speed for a machine to run straight. When the steering lever 22 is tilted to the right, a piston rod 20a for an operating cylinder 20 is expanded and moved equivalently to the tilting operation of the steering lever 22. That means, the right and left planetary transmission mechanisms 9, 9 are in mutually opposite operation and a relative speed difference between right and left steering devices 5, 5 occurs for the machine to be turned to the right. As the tilting of the steering lever 22 is increased, pressure in an oil passage 25 is higher and a turning radius is smaller. This applies also to left turning.

Title: Communication equipment
Inventor: MIYAMOTO HIROAKI
IPC: G06F13/28
Filed: 1993-12-03
Abstract: PURPOSE:To shorten the time needed for transfer of deta to plural LSIs by providing 8 selector to distribute the data to be continuously transferred to the LSIs based on the interpretation of a header. CONSTITUTION:A CPU 1 starts the transfer of date to all LSIs 8, and a DMA circuit 3 occupies a bus 4 to continuously transfer the date stored in a memory 2 to the bus 4. Then a selector 5 interprets the header of data trensferred to the bus 4 through an interpreting part 6. That is, the part 6 switches a switching part 7 according to the transfer destinations. As a result, only a specific transfer line 9 is connected to the bus 4 and other lines 9 are seperated from the bus 4. The part 6 transmits the data on the bus 4 through the specific line 9 until the transfer of data length acquired by the header is completed. When this transfer of data is finished, the next header emerges. Thus the selector 5 changes the LSI 8 of the transfer destination and performs the transfer of data. The bus 4 is released after all data stored in the memory 2 are continuously transferred.

Title: Connector for optical communication
Inventor: TAMURA KAZUHIRO
IPC: G02B6/38
Filed: 1993-12-03
Abstract: PURPOSE:To lessen the connector loss of light transmission and to improve S/N by removing the dust of a light receiving surface, ensuring the connection of a socket and a plug, improving reliability at the time of connection and suppressing extremely the deterioration in transmission performance by connection of a connector for optical communication. CONSTITUTION:The air between the plug 12 and the socket 1 is hermetically sealed and the air in the socket is compressed when the plug 12 is inserted into the socket 1. The air flow by the internal pressure thereof is generated and the air enters from an air inflow port 8, passes the light receiving surface and enters in an air discharge port 4. Finally, the air escapes a discharge valve 3 and is eventually emitted outside the socket 1. The dust on the light receiving surface is, therefore, blown off by the wind pressure of the air, by which the dust on the light receiving surface is discharged together with the air outside the socket 1. The light receiving surface is thereby self-cleaned.

Title: Fuel pump
Inventor: HONDA YOKO
IPC: F02M37/10
Filed: 1991-10-23
Abstract: PURPOSE:To make the fuel pump compact in size by enabling performance of three actions of a damper, a check valve, and a relief valve by means of a single valve element. CONSTITUTION:An upstream channel 21 and a downstream channel 22 of a fuel discharge passage F1 are formed in a housing end wall 1 of the fuel pump, and a ball valve 4 is disposed in a cylindrical space 23, which ball valve is slidable back and forth in a condition of being kept in liquidtight contact with the inner wall thereof. The ball valve 4 is urged, at its backside, by a coil spring 3 to advance to and abut against an opening of the upstream channel 21, thus closing the opening. Even when the fuel pump ceases to operate and a high fuel pressure remains to exist in the downstream channel 22, the ball valve 4 is kept in abutment and closure, thus functioning as a check valve. When the pump starts being operated with the result that the fuel pressure rises, the ball valve 4 makes open the opening of the upstream channel 21 and is retreated in accordance with the fuel pulsation to absorb the same, thus functioning as a damper. When the fuel pressure excessively rises, the ball valve 4 is further retreated to open a relief channel F2.

Abstract: PURPOSE: To provide the document processor which can display an ordinary character string and an expression calculation result together in one cell. CONSTITUTION: When a character is inputted at a cursor position by a character input means 4, a CRT display device 1 displays the inputted character at the cursor position under the control of control means 6 and 7. A specifying means 5 specifies a cursor position at an optional position of a character string displayed on the CRT display device 1 and when setting operation is done after an expression is inputted by an expression input means 4, the control means 6 and 7 finds the calculation result of the inputted expression. The display means 1 displays the expression calculation result at the cursor position under the control of the control means 6 and 7. Consequently, the expression calculation result can be displayed in the cell where the character string is inputted.  In addition, after the expression calculation result found through the expression input operation and its setting operation is displayed, an optional character string can be inputted before and after the expression calculation result.
