Title: Image forming apparatus
Inventor: HASEGAWA HIRONOBU
IPC: H04N1/23
Filed: 1990-05-31
Abstract: PURPOSE:To output formed image data even when it is impossible to continue the double-sided image formation mode by detecting immediately before the start of outputting whether or not the double-sided image formation is possible when the double-sided image formation mode is designated and, switching the mode to the signal-sided image formation mode only when the double-sided image formation mode is impossible. CONSTITUTION:When a double-sided image formation mode is designated by a double- sided mode designating means A, the designation is made effective unconditionally, so that page data is formed, etc. Immediately before an image forming part B starts an outputting process of images for double-sided printing, a judging means C judges the state. Only when the double-sided image formation is detected to be impossible by the means C, a mode switching means D switches the image formation mode to a single-sided image formation mode. Therefore, even if the double-sided image formation is impossible at the time when it is designated, if the image forming part B is turned into the possible state of the double-sided image formation immediately before the outputting process of images for double-sided printing is started, images can be printed on the front and rear faces of a paper according to the double-sided image formation mode.

Title: Detection system for focus position
Inventor: KIKUCHI KEISUKE
IPC: G02B7/28
Filed: 1985-06-28
Abstract: PURPOSE:To detect a focus position by detecting the focus position by utilizing the fact that the difference signal output of a split photodetector is inverted in phase at a focusing point where a reflector is positioned. CONSTITUTION:Divergent light from a laser 1 is converged on the reflecting surface 4 of an optical disk, etc., through a lens 3 and reflected light from the reflecting surface 4 is passed through the lens 3 again and returned to a BDLD 1 which operates as the split detector. The direction of the peak intensity of divergent light from the BDLD 1 is deflected periodically by flowing a high frequency current to divided electrodes. Divergent light 2' whose direction of the peak internsity is deflected periodically is converged on the reflecting surface 4 through the lens 3. In this case, the converged spot 2'' on the reflecting surface 4 is fixed regardless of the deflection when the reflecting surface 4 is positioned at the focusing position (b), but in phase and opposite in phase on the basis of the deflection direction when the reflecting surface 4 is at positions (a) and (c) before and behind the focusing point. Consequently, which side of the focusing point the spot is defocused to is detected from the phase of the difference signal.

Title: Heterojunction field effect transistor
Inventor: INOUE KAORU
IPC: H01L29/778
Filed: 1993-06-15
Abstract: PURPOSE:To improve the lowering of mutual inductance in a high gate voltage region by a method wherein the heterostructure, consisting of an undoped InGaAs mixed crystal thin layer having the value of InAs composition of specific range and an undoped GaAs thin layer formed on the mixed crystal thin layer, is used as the main channel layer. CONSTITUTION:A channel layer is formed by an undoped InGaAs mixed crystal thin layer, having InAs composition of 10 to 25%, and GaAs layer formed thereon. As a result, electrons are accumulated in the GaAs layer when gate voltage, which induces the electron density exceeding the saturated electron density for the quantum well of the InGaAs layer, is applied, but as the GaAs layer is a non-doped layer, a high mobility and a high speed of electrons can be maintained, and the lowering of mutual conductance can be prevented. Also, an abnormal increase in mutual inductance can be prevented even when high gate voltage is applied.

Abstract: PURPOSE:To reduce the area of a booster circuit and improve the degree of integration, implanting ion species of an impurity having the same conductivity type as that of one semiconductor substrate into the substrate by using high energy and controlling the depth profile of impurity concentration near a source- drain junction in a channel region. CONSTITUTION:In a booster circuit for a semiconductor nonvolatile memory, the ion species 3 of an impurity having the same conductivity type as that of one semiconductor substrate 1 are implanted into the substrate 1 by using high energy, and the impurity is controlled so that the peak of impurity concentration is brought near a source-drain junction in a channel region. Impurity concentration under the source-drain junction is lowered because the ion implantation of a WELL region and drive-in heat treatment are not executed regarding the impurity concentration of a channel section. Accordingly, the back-gate effect of MOSFETs is reduced, and the boost voltage of the booster circuit can be composed of a small number of the MOSFETs.
