Title: Process control system for picture forming device
Inventor: KITAHARA FUMIHIRO
IPC: G03G15/08
Filed: 1990-07-07
Abstract: PURPOSE:To eliminate wrong detection and make picture forming operations smoother by not performing developer presence/absence detection after performing the detection for a fixed period of time after a main motor is started to carry printing paper and always performing toner presence/absence detection while the main motor is rotated. CONSTITUTION:An upper structure body 1 is provided with a sensor 9 which detects the presence/absence of a developer 3 fitted to a lower structure body 2 in a removable state and the presence/absence of toner in the developer 3. It is contrived that the developer 3 presence/absence detection is performed for a fixed period of time (several seconds) only after a main motor 11 is started and not performed at the other timing and toner presence/absence detection is always performed while the motor 11 is rotated so that picture formation can smoothly be performed. Therefore, a display 'No Developer' is not wrongly detected and displayed on a console panel and picture forming operations can smoothly be performed.

Title: Semiconductor device and manufacture thereof
Inventor: OKUBO TOSHIO
IPC: H01L21/768
Filed: 1986-08-01
Abstract: PURPOSE:To reduce the contact resistance of a connecting section between Mo and Al, and to obtain an MOSFET having excellent high-frequency characteristics by preventing the interposition of an oxide between a section consisting of a high melting-point metal and a section connected to the section consisting of the high melting-point metal and composed of a wiring metal. CONSTITUTION:An Mo electrode 5 is formed onto the surface of a semiconductor base body, and a semiconductor element is shaped into the base body by using the Mo electrode 5. An oxide film 10 coating the upper section of the semiconductor element is bored to expose one part of the Mo electrode 5, and the exposed surface of the electrode 5 is dry-etched. Consequently, an oxide on an Mo surface is removed, and Al is evaporated onto the Mo surface under the state, thus shaping a wiring Al electrode 9. Accordingly, the Mo oxide on the Mo surface is taken away completely, thus reducing contact resistance in a connecting section between Mo and Al.

Title: Mis type field-effect transistor
Inventor: MAEZAWA KOICHI
IPC: H01L21/338
Filed: 1987-07-20
Abstract: PURPOSE:To obtain a function as a MISFET even if a gate voltage applied to a gate electrode layer 7 is comparatively lower, by composing a second semiconductor layer which has a plane orientation except a plane (100) in its main plane and has inner distortion. CONSTITUTION:A semiconductor layer 24 is formed in a crystal structure of a zincblende type, and it has a plane bearing with a plane (111) A in its main plane, and besides it has inner distortion and a non-diagonal component of a piezo distortion tensor. Since the semiconductor layer 24 has a lattice constant smaller than a semiconductor layer 23 has, an internal electric field is induced by the semiconductor layer 24 so that electrons are made to move from the side of the semiconductor layer 23 toward the opposite side of the gate electrode layer 7. A height of a barrier of the semiconductor layer 24 is made higher at least than an energy component, which is based on the internal electric field induced by the semiconductor layer 24, and a height of the barrier of the semiconductor layer 4. Hence a function as a MISFET can be obtained with prescribed characteristics even if a gate voltage applied to a gate electrode layer 7 is made high.

Title: Compression system for image data
Inventor: YOSHIDA SHIGERU
IPC: H04N1/41
Filed: 1986-07-31
Abstract: PURPOSE:To prevent deterioration in picture quality by dividing a cluster whose approximate error is maximum when the approximate error is larger than a threshold value, finding respective representative gradations, and carrying on this operation until the approximate error becomes smaller than the prescribed threshold value. CONSTITUTION:When the approximate error is larger than the prescribed threshold value, a centroid generating means 5 finds a new centroid by referring to the contents of a resolution component memory and sets it as a new representative gradation in a representative gradation sending means. If the error does not decrease even when the centroid generation is repeated prescribed times, the cluster whose error is largest is divided and given approximity is calculated again by clusters. This operation is repeated and when an approximity deciding means 7 detects the approximate errors of all the cluster decreasing below the prescribed threshold value, a representative gradation component is outputted to a terminal 8 and a resolution component is outputted from the resolution component memory 4 to a terminal 9. Consequently, the deterioration in picture quality is precluded.
