Title: Thin film magnetic head
Inventor: SHIMIZU OSAMU
IPC: G11B5/31
Filed: 1988-10-04
Abstract: PURPOSE:To obtain the magnetic head which exhibits good corrosion resistance even under high-temp. and high-humidity conditions by composing the essential components of a protective layer of prescribed amounts of SiO2 and one or two kinds of WO3 and MoO3. CONSTITUTION:The essential components of the protective layer 16 are com posed of 20 to 95mol% SiO2 and one or two kinds of 5 to 80mol% WO3 and MoO3. Since the Vickers hardness Hv of this protective layer 16 is in an about 400 to 700kg/mm<2> range, the layer is not too soft and has good matching of a wearing property with generally used amorphous Co systems, 'SENDUST(R)', etc., (Hv is about 650kg/mm<2>). Generation of unequal wear in the magnetic layer is thus obviated. Strain s are small and residual stresses are hardly generat ed even if the protective layer 16 is directly formed on the magnetic layer 15 by a sputtering method and, therefore, the peeling of the protective layer 16 does not arise and the protective layer is not deteriorated in properties and resists corrosion well even under the high-temp. and high-humidity conditions. The protective layer 16 does not peel and crack even if the protec tive layer 16 is mechanically worked after the formation of the magnetic layer 15. Reactive etching by a gaseous freon system is possible as well.

IPC: H04N5/74
Filed: 1992-09-18
Abstract: PURPOSE:To provide a method and a device for displaying an image displaying the bright and high quality image with a wide dynamic range and with an excellent gradation display characteristic even in the case of a dark image by using a spatial optical modulation element. CONSTITUTION:A peak level Vp is detected at every fixed period of a video signal Vin supplied from the outside. A gain Gs=Vp/Vo is calculated from the detected peak level Vp. However, a reference peak level Vo is defined as the standard peak level of the supplied video signal. After the gain Gs is calculated, the video signal level is modulated as Vc=Vin/Gs. The modulated video signal Vc is converted to a drive signal, and the spatial optical modulation element is driven by it. Simultaneously, a light output level Lout in a light emission part is made Lout=GsXLo by using the gain Gs. Where, Lo is a reference light output level in the light emission part. By repeating mentioned processing at every fixed period, the bright image with an excellent gradation characteristic and a black display characteristic than usual is displayed.

Title: Food container
Inventor: AMANO NORIO
IPC: B65D1/28
Filed: 1989-09-25
Abstract: PURPOSE:To make a container resistant to heating by an electronic oven, light in weight, rich in insulative property and free from breakage due to shock by a method wherein the non-foam film of one thermoplastic resin is bonded to the one side of the foam sheet of other thermoplastic resin and the bonded sheets are shaped into the form of a container with the non-foam film face inward. CONSTITUTION:A foam sheet of polyester resin is formed into a container and the non-foam film of the same polyester resin is attached to the inner surface of the container. In this case, since the polyester resin film has a uniform thickness and is free from an extremely thin part unlike foam wall, it has sufficient force to isolate vapor therefrom and, therefore, will not allow the intrusion of vapor into the foam sheet of polyester resin. This provides the container light in weight with an insulative property, less breakable due to shock and good in heat resistance.
