Title: Fire-proof louver
Inventor: YAMADA OSAMU
IPC: F24F11/08
Filed: 1988-02-29
Abstract: PURPOSE:To produce fire-proof louvers, by attaching a thermal expansible fireproof material on the surfaces of fins which are made of thin metal plate with approximately U-shape. CONSTITUTION:A louver 2 includes a steel frame 5, a plurality of metallic fins, and thermal expansible fireproof material 7 attached on the fins. A fireproof door 1 provided with a louver 2 of said constitution functions as a conventional louver allowing air to flow through under ordinary circumstances, but in case of a fire, air ventilation clearance between fins are closed by the expansion of the thermal expansible sheets 7, so that it exhibits its fireproof function equivalent to a fire wall, intercepting air flow. It is also highly reliable without troubles of malfunctioning and maintenance due to absence of mechanical construction. In addition, ventilation capacity, dimensions and shape are easily changeable according to conditions in a work site.

Title: Abnormality decision method for air compressor
Inventor: HASEGAWA MASARU
IPC: F04B49/10
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To grasp temperature variation due to an internal abnormality of a compressor itself accurately in early stage even when the external temperature fluctuation is significant by setting a limit temperature depending on the temperature fluctuation of outer environment where the air compressor is installed. SOLUTION: An air compressor 1 is arranged with temperature sensors 3, 4 for measuring the suction air temperature T1 and the delivery air temperature T2' respectively, and temperature information is delivered to an operation control section 5 where a theoretical delivery air temperature T2 is operated constantly according to a thermodynamic theoretical formula. Furthermore, a limit temperature T4 being referred for deciding abnormality is determined by adding an abnormality management value T3 to the delivery air temperature T2. The limit temperature T4 reflects the ambient temperature at a moment of time when the suction air temperature T1 is measured and the limit temperature T4 is compared with an air temperature T2' actually measured on the delivery side.

Title: Magnetic recording medium
Inventor: FURUHATA KENICHI
IPC: C09D5/23
Filed: 1990-02-28
Abstract: PURPOSE:To improve the surface smoothness of the medium and to improve traveling property and reliability of the medium by specifying the amt. of a binder incorporated into the magnetic layer. CONSTITUTION:High-density recording can be realized by specifying the amt. of the binder to <=15 pts.wt. to 100 pts.wt. of the magnetic powder in the magnetic layer. When the relative amt. of the binder in the magnetic layer is regarded as 100 pts.wt., 20-200 pts.wt. of abrasive having <=0.5mum center particle size and 20-150pts.wt. of liquid or solid lubricant are also incorporated into the layer. Since lubricating property and abrasive property are largely improved, such problems as absorption, adhesion and stick-slip and liability to unable state of traveling can be avoided. These problems sometimes occur conventionally in a high-density recording medium having largely improved surface smoothness of the magnetic layer. Thereby, traveling property and reliability of the medium can be improved.

Filed: 1988-03-01
Abstract: PURPOSE:To realize a shape suitable for reducing resin flashes by a method wherein the entirely of a lead frame or its outer lead section is further pressed in order that its cross section is rectangular. CONSTITUTION:The entirety of a lead frame or its outer lead section after punching is further pressed between planar metal molds 14 and 15 for conversion of its cross section into a form approximating a rectangle. In the case that a metal material 11 is employed for the lead frame, the radius of curvature at a corner may be as small as half of that in a conventional design. This design suppresses the generation of resin flashes in a subsequent resin-sealing process, improving the yield of semiconductor devices in terms of appearance. Similar effect may be obtained when the outer lead section only is pressed between the planar metal molds for conversion into a form approximating a rectangle.
