Title: Epitaxy method
Inventor: SUGAO SHIGEO
IPC: H01L21/203
Filed: 1989-03-22
Abstract: PURPOSE:To obtain a high-purity growth layer having little contamination by carbon by a method wherein atomic hydrogen is irradiated on the surface of a substrate during an epitaxial growth. CONSTITUTION:A GaAs substrate 13 is installed on a substrate holder 12 and the interior of a growth chamber 10 is evacuated in a high vacuum. After that, TEG(triethyl gallium) molecules are irradiated from a TEG molecular beam source 15 and one molecular layer is chemically adsorbed on the surface of the substrate 13. Then, atomic hydrogen is irradiated from an atomic hydrogen source 16, an ethyl group of the chemical adsorption layer is changed into ethane gas and the gas is removed from the surface of the substrate 13. Then, As molecules are irradiated from an arsenic molecular beam source 14, are made to bond to Ga atoms on the surface of the substrate 13 and one molecular layer consisting of GaAs is formed. By repeating the above process, a GaAs single crystal thin film of a necessary thickness is grown. By irradiating the atomic hydrogen on the substrate surface like the above manner, an incorporation of carbon into a growth layer is inhibited and a high-purity growth layer having little contamination by carbon is obtained.

Title: Image forming device
Inventor: KAWAI NOBUYUKI
IPC: G03G15/01
Filed: 1988-03-22
Abstract: PURPOSE:To prevent the stain of an image by gradually advancing a developing device which comes to the position of developing height toward a photosensitive body with the up-and-down motion of an elevating supporting body and guiding the developing device so that the developing device is brought into contact with the photosensitive body in the position of developing height. CONSTITUTION:As the developing devices 7b, 7c, 7m and 7y which are set to be in the position of developing height next approach to the position of developing height with the up-and-down motion of the elevating supporting body 15, they are guided by a guiding means 33 to be advanced toward the photosensitive body 6. After reaching the position of developing height, they are set in the position where they substantially come into contact with the photosensitive body 6, at the same time or in a little moving time. Since the advancing motion of the developing devices 7b, 7c, 7m and 7y toward the photosensitive body 6 is performed gradually with the up-and-down motion of the elevating supporting body 15, shock and vibration occurring when the developing devices 7b, 7c 7m and 7y substantially come into contact with the photosensitive body 6 are small. Thus, the stain, etc., of the image caused by the scatter of developer can be prevented.

Abstract: PURPOSE:To make an undue vibration at starting and stopping restrainable, by operating an elastic film deformation restricting device at the nonrestricting position while an on-off valve at the closing position, respectively, excepting the specified value of actuator working pressure, in case of a car engine mount. CONSTITUTION:At a high freugency range of an engine, a controller 32 controls each of selector valves 26 and 31, opening an on-off valve 14, and each hydraulic chamber 21b of actuators 21 is interconnected to a tank 41, whereby vibrations are absorbed by free deformation of each elastic film 7.

Title: Method for checking registration data
Inventor: FUJIWARA MASAFUMI
IPC: G06F12/16
Filed: 1989-03-20
Abstract: PURPOSE:To improve the availability of a device and to reduce the trouble to input the registration data again by providing a checking means which checks the registration data stored in 1st and 2nd nonvolatile storage means and checking the registration data double. CONSTITUTION:When the device is powered on, the checking means 10 checks the registration data stored in the 1st storage means 4 primarily and transfers the registration data stored in the 1st storage means 4 to the 2nd storage means 5 when the data is correct. If an error is detected as a result of the primary check, the checking means 10 checks the registration data stored in the 2nd storage means 5 secondarily. If an error is detected as a result of the secondary check, the error detection is reported, when the checked data is normal, the registration data stored in the 2nd storage means 5 is transferred to the 1st storage means 4 and employed as registration data. Consequently, the stop state of the device and the frequency of data reregistration are reduced to improve the availability of the device and reduce the trouble for the reregistration.

Title: Manufacture of plastic film
Inventor: KINOSHITA SHUICHI
IPC: B29L7/00
Filed: 1986-03-28
Abstract: PURPOSE:To prevent the generation of insulation defect of a plastic film by a method wherein a cleaner, constituting of the woven fabric or the knitted fabric of long fibers, is contacted with at least one surface of the plastic film directly to rub the surface and remove dust adhered on the plastic film. CONSTITUTION:The base material 8 of a roll is provided with a fiber assembling body 9 with the compression modulus of elasticity of 4-20% on the surface thereof and, further, the woven fabric or blaided fabric 10 of long fibers is provided thereon. When a cleaner of this constitution is used, the generation of scratches on a film may be prevented upon removing dust and dust removing effect may be increased more by a mechanism wherein the fiber assembling body 9 absorbs and holds the dust, collected by the woven or blaided fabric 6 from the film. When the compression modulus of elasticity becomes lower than 4%, dust holding function becomes insufficient and the preventing effect of the generation of the scratches on the film becomes low also. On the other hand, when the compression modules of elasticity exceeds 20%, the removing effect of dust from the film becomes small.

Title: Production method of semiconductor integrated circuit system

IPC: H01L21/331
Filed: 1979-06-04
Abstract: PURPOSE:To improve a carrier input efficiency and make a device small by designing the emitter of a npn transistor as a buring layer and a vertical structure and its base width controllable with a diffusing depth. CONSTITUTION:A P-buring layer 3 is formed selectively at a n<+> type Si basic board 1 to accumulate a n<-> epi layer 4 and produce a P-output layer 3'. A P layer 5 is produced with a SiO2 as a mask and a n<+> layer 6 is formed in the P layer 5 by striking a P ion into a SiO22' opened selectively. Then a grounded terminal Em is established at the basic board 1 to attach electrodes B, C1-C2 to its surface. This design accomplishes I<2>L system of both an inverter by the emitter 1 and a base 5 collector 6 and an injecter by the emitter 3, emitter 4 and collector 5. This structure ensures an ability of high speed movement to increase an efficiency of a carrier input. The fact that the emitter 1 of the injector is placed opposite to the collector 6 of the inventer decreases an ineffectual carrier and minimizes an ineffectual electric power.
