Title: Apparatus for locking open/close cover
Inventor: SATO WATARU
IPC: G12B9/04
Filed: 1989-02-27
Abstract: PURPOSE:To rapidly and easily open/close an open/close cover by providing an original position restoring spring for opening/closing the open/close cover. CONSTITUTION:When a part B is pushed down toward an arrow C by an original position restoring spring 10, the tip of a lock plate 31 is lifted while it is restored to the original position when the part B is released. At the time of closing an open/close cover 2, this open/close cover 2 comes against the tip of the lock plate 31 to have the tip of the lock plate 31 lifted, and the open/ close cover 2 is locked further by closing it so that it cannot be unlocked from outside thereby preventing the open/close cover 2 from being opened. At the time of opening the cover 2, by pushing down the part B toward the arrow C the tip of the lock plate 31 is lifted to be unlocked thereby permitting the cover 2 to be opened.

Title: Electrophotographic device
Inventor: KAMIYAMA MITSUAKI
IPC: G03G15/043
Filed: 1986-03-03
Abstract: PURPOSE:To surely detect original size regardless of the kind of the original by using the light of the wavelength region of the low spectral reflectivity of an original cover having the spectral reflectivity corresponding to the wavelength region of the spectral sensitivity of an electrophotographic sensitive body to identify the original. CONSTITUTION:The original is identified by using the light of the wavelength region of the low spectral reflectivity of the original cover having the spectral reflectivity corresponding substantially to the wavelength region of the spectral sensitivity of the electrophotographic sensitive body. There is no inconvenience even if the light having no sensitivity to the photosensitive body out of the light reflected from the original cover does no longer exist and therefore the ill effect of the reflectivity change of the original cover on the photosensitive body can be prevented by approximating the spectral reflectivity of the original cover to the reflectivity of the photosensitive body as far as possible. For example, the photosensitive body of which the photoconductive layer is selenium has the sensitivity on the short wavelength side of <0.6mum as shown by a solid line A. A satisfactory result is therefore obtd. if the original cover having such spectral reflectivity as shown by, for example, a solid line B is used.

Title: Grazed resistor material
Inventor: IZEKI TAKESHI
IPC: H01C7/00
Filed: 1990-02-27
Abstract: PURPOSE:To obtain high-performance resistors capable of forming circuits with base metal wiring conductors such as Cu by constituting materials of metal silicides, IV a, V a, VI a group oxides, and borate glass with less than 3wt.% of SiO2 content. CONSTITUTION:This material is constituted of metal silicides, IV a, V a, VI a group oxides, and borate glass with less than 3wt.% of SiO2 content. This glazed resistor material has B2O3 in borate glass and this B2O3 chemically reacts with IV a,V a,VI a group oxides, metal silicides, and Si upon baking to produce IV a, V a,VI a group metal borides. These metal borides form fine conductive networks in a resistor because of their high weatherabilities and their production upon chemical reaction. Besides the SiO2 content of more than 3wt.% in glass suppresses reaction and allows formation of excellent resistors. This process can provide a glazed resistor material which can be used for base metal wiring conductors such as Cu wiring conductors and can form high-performance resistors by baking in a non-oxidizing atmosphere.

Outputs of Tr10, 11 are fed back negatively to the inversion input of amplifier 6 through differential amplifier 14, thereby changing the bias values equal to Tr10, 11 according to the input level.
