Title: Manufacture of composite piston
Inventor: TAKAHASHI TOSHIO
IPC: F02F3/00
Filed: 1984-07-07
Abstract: PURPOSE:To enable high combining and anchorage strength with a skirt made of FRP and excellent heat-resisting separation properties, by a method wherein an FRP fibrous is wound around a combining part of the skirt and a mandrel, which is heated by abutting a heated molding die against the same after that. CONSTITUTION:In case of manufacture of a piston crown 1 through die casting the whole or a part of a protrusion 3 is molded unitarily on a combining part 2 of a skirt. A continuous surface is formed with the combining part 2 of the skirt and a mandrel 10 and FRP fibrous material 4 such as fiber or a fiber bundle the circumference of which is impregnated with resin is hung on the protrusion 3 and wound around strongly. A cellophane tape is wound around the outside of the skirt, against which a heated molding die is abutted for curing the FRP. The precise FRP is obtained as tightening force is generated by contracting the cellophane tape. A reduction of an engine noise can be contrived by making use of damping properties of the FRP and an improvement in fuel consumption resulting from weight saving is realized.

Title: Ofdm receiver
Inventor: TAGA NOBORU
IPC: H04L7/00
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To suppress the effect of disturbance of an adjacent channel when receiving a signal of a 1st segment (narrow band) at an end of a frequency band (channel), by using a tuner having only a band-pass filter with 3 segments (broadband). SOLUTION: A tuner 10 has only a band-pass filter with 3 segments (broadband), offsets a channel selection frequency of the tuner to suppress the effect of adjacent channel disturbance in the case of receiving a signal of 1 segment (narrow band) at an end of a frequency band (channel), and conducts channel selection control, so that the frequency offset is canceled by an orthogonal detection circuit. Furthermore, in the case of receiving a 3-segment (broadband) signal, the tuner 102 does not offset a channel selection frequency.

Title: Design backup system for electronic parts mounting process
Inventor: TANAKA HIROYUKI
IPC: G06F17/50
Filed: 1990-06-01
Abstract: PURPOSE:To reduce the overall development cost and to obtain products of high reliability in a short time by automatizing the design backup system of the electronic parts mounting process throughout and to improve the reliability of the system to shorten the development period and reducing the labor in the trial manufacture stage. CONSTITUTION:Stored data related to a printed circuit board and various elements and temporary arrangement data of electronic parts is transferred to an analysis processing device by on-line. Electronic parts are virtually arranged on the printed circuit board on a CRT, and simulation is repeated till a desired reliability is obtained. Optimum arrangement data obtained after completion of simulation is transferred to a printed circuit board pattern design and producing device, and the printed circuit board is produced. Thus, products of high reliability are obtained in a short time because the process of simulation is performed by inline. Since the process of simulation is executed on the CRT, the trial manufacture stage is unnecessary to reduce the development design cost.
