Title: Method and device for dicing
Inventor: UEKURI KOUICHI
IPC: H01L21/301
Filed: 1987-07-29
Abstract: PURPOSE:To contrive extension of life of a blade, by a method wherein only pure water is fed to the blade by interrupting feed of carbon dioxide between a first wafer cutting process and second wafer cutting process. CONSTITUTION:A device 1 is constituted of a pure water feed device 2, a, cutting-off device having a blade 5, a detecting device 12 detecting a wafer 10 on a mount 9 and a device 13 controlling feed of carbon dioxide by providing them.

Title: Liquid crystal display element
Inventor: FUJIWARA YOSHIYUKI
IPC: G02F1/133
Filed: 1985-08-30
Abstract: PURPOSE:To increase contrast and eliminate an irregularity in light leak, and to improve the quality of a display by providing a light shield layer which impedes the transmission of light except at a display part in a negative type liquid crystal display element. CONSTITUTION:The light shield layer 12 which impedes the transmission of light is formed on the internal surface of the opposite substrate 4 of the negative type liquid crystal display element except at the display part. Consequently, when light L is irradiated by a light source 11 arranged on the rear surface side, the light L corresponding to a no-display part (background part) is hardly transmitted through the light shield layer 12 and only the display part impressed with a voltage between a display electrode 1 and a counter electrode 3 illuminates. Consequently, a high-contrast display is obtained and there is no irregularity in light leak at the no-display part even when the visual angle to the display screen is varied. Consequently, an element of high display quality is obtained.

Filed: 1993-08-02
Abstract: PURPOSE:To set a lot of test modes with the small number of keys by setting the test mode while combining the key-on time and key-off time of any prescribed key among plural operation keys on a control panel. CONSTITUTION:One of keys such as a start key or an oven key at the key input part of the control panel is set as a test mode setting key. When key-on information is inputted from a key switch circuit 15, a control part 10 judges whether a turned-on key is the test mode setting key or not and when it is the test mode setting key, a key-on timer is started. Then, this test mode setting key is continuously turned on longer than two seconds and turned on again within two seconds so that the mierowave over can be set in the test mode. Further, test contents can be successively switched by operating the setting key as well. Thus, many kinds of tests can be executed even by a machine type provided with a small number of operation keys, and the operation is simplified as well.

Title: Water-resistant printing film laminated steel panel
Inventor: MORI KOJI
IPC: B32B27/36
Filed: 1994-07-22
Abstract: PURPOSE:To obtain a printing film laminated steel panel excellent in water resistance by providing a colored primer layer composed of a thermosetting resin between a steel panel and an adhesive layer and forming the adhesive layer as a pigment free one. CONSTITUTION:A primer layer becomes a matrix denser than an adhesive layer because it is composed of a thermosetting resin. Therefore, even if pigment is added, the matrix keeps the dense state and prevents the penetration of water. Since an adhesive layer contains no pigment, the denseness thereof is enhanced and water becomes hard to penetrate into the adhesive layer and the bonding strength of the adhesive layer to upper and lower primer layers and a printing polyethylene terephthalate film is enhanced. As a resin of the thermosetting colored primer layer, one high in the bonding strength with a steel panel is pref. and, for example, an epoxy resin or a polyester resin may be used. A curing agent may be added in order to enhance the denseness as the matrix to pigment.
