Abstract: PURPOSE:To polish the surface to be polished of a base at an uniform rate by building a temperature control means for generating a prescribed temperature distribution along the radial direction of the base placing surface in a base holding base. CONSTITUTION:A base 25 is held by a base holding base 26, and the temperature of its base placing surface is regulated by heaters 28a, 28b, for example, to have a low temperature in the central part and a high temperature in the outer circumferential part. This is rotated around a holding base rotating shaft 27, and an abrasive 22 is supplied onto an abrasive cloth 29 from an abrasive supply pipe 21 in the state where a rotating fixed plate 23 is also rotated around a fixed plate rotating shaft 24. The surface to be polished of the base 25 is slid onto the abrasive cloth 29 to polish the surface to be polished of the base 25. The temperature distribution of the base placing base is regulated so that the high molecular particle present on the sliding surface between the abrasive cloth 29 and the base 25 is differed in hardness between the central part and outer circumferential part of the sliding surface. Thus, the surface to be polished of the base 25 can be polished at an uniform polishing rate.

Title: Breather tube device
Inventor: MIYAZAKI SHINJI
IPC: B60K15/035
Filed: 1987-01-28
Abstract: PURPOSE:To secure an air bleed function in a fuel tank by a breather tube till the next fuel supply takes place by constituting backflow fuel to the fuel tank from a receiver tank to be discharged in a way of utilizing inertia force at the time of vehicle braking. CONSTITUTION:When fuel is supplied to the inside of a fuel tank 1 from a fuel supply pipe 3, the fuel flows into a receiver tank 8 from an opening 10 at a spot where it is reached to the opening 10 of the receiver tank 8 after going beyond a projecting part upper edge 4. And, when the fuel is reached to a level of a tube 7, fuel supply becomes uncontinuable, thus a maximum level W is determined. Then, when a vehicle is braked in the state that the fuel is reduced by consumption and the opening 10 is projected from the level, the fuel is tilted by inertia force, so that backflow fuel inside the receiver tank 8 is discharged to the inside of the fuel tank 1. In consequence, fuel inside the breather tube 5 flows into a fuel sump 11 of the receiver tank 8, thus an air discharge function of the fuel tank 1 is restored.

IPC: B29C45/00
Filed: 1983-02-08
Abstract: PURPOSE:To obtain the composite into which the plate like member made of different material is integrally caused to adhere, while obtaining FRP molded product by using a resin injection molding process. CONSTITUTION:Injection mold is composed of a top force 1 and bottom force 2. A rubber seal 4 is provided at the lower part of the force 2, and on said rubber seal, a plate like member 5 such as a dressed plate coated with metal is placed in such a manner that the decorated surface of the dressed plate is in contact with the bottom force. Next, the layer 6 of glass-continuous fiber mat is placed on all the periphery of the surface of the force 2. Then the force 1 is lowered, and after clamping the mold, curable resin component is poured into the cavity from a pouring hole 3, and is cured. After the product has been taken out from the mold, the FRP composite with exposed decorated surface is obtained. In the above method, after the plate like member 5 has been placed, a core member 7, e.g. synthetic resin form, plywood or glass wool which is slightly smaller than the plate member may be also placed on said plate member. Thus, the composite is able to be produced.

IPC: H04B1/69
Filed: 1987-01-30
Abstract: PURPOSE:To improve the S/N in the entire equipment by using an oscillated frequency deciding the transmission speed of information through frequency division as a clock for a pseudo noise code generator and a carrier inputted to an information modulation section and using a specific frequency as the carrier and the clock of the pseudo noise code generator. CONSTITUTION:When a signal of 2.456MHz is outputted from a Baud rate oscillator 16, an information modulation section 12 modulates the carrier of 307.2KHz inputted from a frequency divider 18 by using the information sent from an information section 11. When the modulated information is inputted to a balanced modulator 13, the balanced modulator 13 spreads the input signal into a broad band of 153.6KHz-460.8KHz by using a 153.5KHz clock sent from a PN code generator 14. A band limiter 15 sends a spread information signal over a broad band to a lighting line 30 through a lighting line I/F 40. A reception section 20 receives the said spread information signal. The spread information signal is sent to a balanced modulator 22 through a band limiter 21. In this case, noise having a frequency below 120KHz generated from an electromagnetic cooking apparatus or the like is cut off.
