Patent JP-H0462346-A (JP)
Title: Clean room
Inventor: TANAKA TOMIO
IPC: E04H5/02
Filed: 1990-06-29
Abstract: PURPOSE:To reduce extremely deposit of dirt and dust in an enviromental part and to maintain a highly clean enviroment by forming a sloping surface for guiding smoothly a vertically laminar stream in the vicinity of side walls to a floor surface in the enviromental part between the floor surface and inner surfaces of the side walls. CONSTITUTION:In an enviromental part between a floor surface and inner surfaces of side walls 1, a sloping surface 3a is formed. Due to existence of the sloping surface 3a, a vertically laminar stream in the vicinity of the side walls 1 is guided smoothly to the floor surface 2 and made to flow toward an discharging duct without staying in the enviromental part. In this instance, the sloping surface 3a is not limited to a flat surface, and a curved surface will do and it is preferable that the curved surface draws an arch contacting with the each of the side walls and floor surface in the cross section. Further, as possibility of depositing of dirt and dust is remarkablly large in corner parts of the floor surface 2, a flat sloping surface 3c or a smoothly curved sloping surface may be formed only in the corner parts of the floor surface 2. If a sloping surface is formed in other enviromental parts than the corner parts of the floor surface, the sloping surface has only to be formed in a flat or curved surface continuous to the enviromental parts.

Abstract: PURPOSE:To reproduce a broad band high definition signal with S/N higher than that of a conventional home use VTR by applying frequency modulation to a time base compression color difference signal with a time base reference signal added thereto and using another head to record the modulated signal between tracks on which a conventional color under system video signal is recorded. CONSTITUTION:An NTSC composite video signal is inputted from an input terminal 4 of a recording circuit section 1 and a Y/C separate circuit 5 separates the video signal into a luminance signal Y and a chrominance carrier signal C. The luminance signal Y and the chrominance carrier signal C of the video signal are inputted from a 2nd input terminal and a switch circuit 7 switches Y, C signals from the circuit 5 and the terminal pair 6 into an optional input signal. The Y signal from the circuit 7 is modulated by the circuit 9 via a memory circuit 8. Furthermore, the C signal from the circuit 7 is modulated into a lower frequency than that of the Y signal at a conversion circuit and the circuit 11 adds the modulated signal to the Y signal and the resulting signal is inputted to a recording amplifier 12. Moreover, the C signal from the circuit 7 is demodulated into color difference signals R-Y, B-Y at the circuit 13 and compressed by the circuit 14 and added to vertical synchronizing signal and horizontal synchronizing signal by the circuits 15, 16 and an electromagnetic conversion section 2 uses other head to record the color under system video signal between recorded tracks.

Abstract: PURPOSE:To achieve highly accurate electric discharge machining by arranging a reinforcing member immediately below the column fixing section thereby suppressing the back/fro inclination of column to be induced through flexure of bed due to transfer of the center of gravity of saddle. CONSTITUTION:A reinforcing member 12 is arranged immediately below the fixing section 1b of column on the upper face of bed 1. Said reinforcing member 12 is constructed into single sheet having U-shaped cross-section.

Title: Manufacture of rape-earth magnet
Inventor: WATANABE TERUO
IPC: H01F1/08
Filed: 1989-07-04
Abstract: PURPOSE:To retain improved magnetic characteristics and restrict or prevent cracking on machining by mixing a powder of R-T-M ferromagnetic alloy which mainly consists of a rare-earth metal R, an iron transition metal T, and a metalloid M and that of a ferromagnetic metal with improved hot deformation capability or an alloy, performing compression-formation, and then by performing hot plastic machining. CONSTITUTION:There are B, C, N, P, Si etc., as a metalloid M. It is desirable to have the content of R-T-M ferromagnetic alloy M to be adjusted to 0.9wt.% or more. Increase in content of M generally deteriorates hot deformation capability. However, by adding a second powder consisting of a ferromagnetic metal or an ally with higher hot deformation capability than this alloy powder and then performing hot plastic machining of this compressed forming body, the problem of cracking is solved or restricted. It is desirable to use an R-T-M ferromagnetic alloy which is similar to the above with its content of M being less than 0.9wt.% as a second powder.
