Title: Nonvolatile semiconductor device
Inventor: SATO YOSHIO
IPC: H01L29/788
Filed: 1989-02-04
Abstract: PURPOSE:To control the threshold voltage of a memory transistor by changing a distance between an impurity diffusion layer on the selective transistor side of the memory transistor and an impurity diffusion layer on the memory transistor side of a selection transistor. CONSTITUTION:An impurity diffusion layer 41 on the selective transistor side of a memory transistor and an impurity diffusion layer 43 on the memory transistor side of a selection transistor are separated mutually. Threshold voltage after the erasing of the information of the memory transistor 31 can be controlled by the clearance D of the impurity diffusion layer 41 on the selective transistor side of the memory transistor and the impurity diffusion layer 43 on the memory transistor side of the selective transistor. The clearance D can be controlled comparatively easily. Accordingly, threshold voltage after the erasing of the information of the memory transistor 31 can easily be set at a desired value.

Title: Information recording paper
Inventor: KURIHARA TSUTOMU
IPC: G03G7/00
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To obtain an information recording paper excellent in adaptability for double-sided full-color copying, by preparing the paper in such a manner that the water content just after the package of the paper is opened is in a specified range and that the paper shows specified or lower CD elongation and contraction rate and a specified water absorption after the package is opened. SOLUTION: This recording paper has 4.0 to 6.0% water content just after the package of the paper is opened, <=0.45% CD elongation and contraction rate and <=0.6% water absorption in 30sec after the package is opened at 30 deg.C in 85% RH environment. When the water content of the paper just after the package is opened is <=4.0%, the paper has higher electric resistance, which causes troubles in an image. If the water content is >=6.0%, the deformation amt. of the paper after copying on one surface is large, which is apt to produce image defects in the second surface. Therefore, the water content is preferably 4.3 to 5.5%. If the CD elongation and contraction rate increases, deformation of the paper increases, and thereby, the CD elongation and contraction rate is preferably controlled to <=0.45%. To decrease the water absorption at 30 deg.C and 85% RH, a dry pulp and the like is compounded.

IPC: B60T8/90
Filed: 1991-02-20
Abstract: PURPOSE:To perform reliable detection of failure in operation of a wheel speed sensor during the stop of a vehicle and to perform delicate detection of a trouble more than conventional detection of a trouble. CONSTITUTION:When a trouble detecting false signal from a port (a) of an electronic control device 2 is brought into a LOW level state and a transistor Tr1 is turned ON, and when a wheel speed sensor 1 is disconnected, a capacitor E is not discharged and a potential at a point B is held in a state to be left at 0. Thereby, an output from a comparator CP2 holds a LOW level state. A trouble detecting output signal is brought into a LOW level state during a time in which a trouble detecting false signal is brought into a LOW level state. Namely, a time in which a trouble detecting output signal is brought into a LOW level state is set to a value outside a set time range. From aboves, it is decided by the electronic control device 2 that a wheel speed sensor 1 is failed in operation.

Title: Heat-resistant protective sheet
Inventor: KOBAYASHI MASAKAZU
IPC: B25H1/02
Filed: 1994-02-24
Abstract: PURPOSE:To provide a heat-resistant protective sheet, strong against heat or damage, capable of stably holding parts placed thereon, easily attached to and detached from a working table and capable of being simply replaced. CONSTITUTION:A protective sheet 1 is formed by bonding a resin film 3 to a magnet sheet 2 by an adhesive. The magnetic sheet 2 can be evenly and uniformly applied to the upper surface 10a of a working table 10 over its whole surface by magnetic force in a hardly releasable manner but can be easily detached by the hand to enable the easy replacement of the protective sheet 1. Since the magnet sheet 2 and the resin film 3 have heat resistance, the protective sheet 1 does not receive the effect of heated parts even when the heated parts are placed.

Abstract: PURPOSE:To improve the strength of an electrode deposited with a metallic lead, together with discharge performance, by increasing the content rate of an electron emission material at the discharge surface side of the electrode, and decreasing the rate at the deposited surface side thereof. CONSTITUTION:The powder of a metallic base substance such as Ni and the powder of an emitter of electron emission material such as Ba2CaWO6 are mixed with each other and sintered, thereby forming a sintered electrode 11.

The emitter mixing ratio is set at a maximum value, for example, 40 to 50wt.% in the A region of the surface 11a. In the C region of the surface 11b, the ratio is set at a minimum, for example, 0wt.%. Also, the intermediate B region is so set as to gradually change, according to an inclined line between the A and B regions. As a result, the discharge performance of the electrode 11 at the discharge surface side can be improved, and the strength of a surface deposited with a metallic lead can be increased, thereby increasing the reliability of the electrode 11.

Abstract: PURPOSE:To efficiently transfer the toner image on the surface of a photosensitive body to a transfer form by constituting the photosensitive body and a transfer body of endless belts and setting the roughness of surfaces of endless belts to a value smaller than the particle size of a developer. CONSTITUTION:The roughness of the surface of a transfer sheet 2 is set to a value smaller than the particle size of toner 3, and that of a photosensitive sheet 1 is set similarly. therefore, toner 3 cannot penetrate recessed parts on surfaces of the photosensitive sheet and the transfer sheet, and toner is easily separated from these surfaces at the time of transfer. Consequently, toner is easily separated from surfaces of the photosensitive sheet and the transfer sheet in this image forming device when the toner image formed on the photosensitive sheet 1 is transferred to the transfer sheet 2 or the toner image transferred to the transfer sheet is transferred to the transfer form. Thus, the toner image is efficiently transferred and shading of the image does not occur after transfer to improve the image quality.
