Patent JP-H058229-A (JP)
Title: Powder feeding device
Inventor: OKANO HIROSHI
IPC: B65G53/12
Filed: 1991-06-28
Abstract: PURPOSE:To prevent the clogging of resin in the midway of a piping due to the installation of a carrying screw from occurring and eliminate the troublesome maintenance due to the installation of a filter in the feeding of air. CONSTITUTION:Air flow A is produced in a piping 101 by mounting air feeding means 141 and 142 in the midway of the piping 101. On the other hand, the exhaust port 103 of the piping 101 is opened through a powder recovering pipe 130 in a hopper 110. Thus, ground resin in the piping 101 is smoothly carried with the air flow A, resulting in preventing the clogging of the resin at the terminal part of a screw 120. Further, by sending back ground resin, which passes through the exhaust port 103 together with delivering air, through the powder recovering pipe 130 into the hopper 110, the ground resin is prevented from scattering outside the device concerned. As a result, a filter, which is used heretofore for preventing the resin from scattering, is omitted and, at the same time, the changing and cleaning of the filter is omitted and easy maintenance is realized.

Title: Forming method for thin film semiconductor layer
Inventor: HAYASHI HISAO
IPC: H01L21/336
Filed: 1988-07-26
Abstract: PURPOSE:To simplify a process and form a selective oxide film free from bird's beak by simultaneously performing the crystal growth of an active layer and the formation of the selective oxide layer for element isolation. CONSTITUTION:On an insulative substrate 1, a polycrystalline or amorphous non-single crystalline thin film semiconductor layer 2 is formed; an oxidation resistant film 4 like Si3N4, is formed selectively on the semiconductor layer 2; then by projecting an energy beam, like excimer laser, on the whole surface in an oxidizing atmosphere, the exposed semiconductor layer 2 is selectively oxidized, and the semiconductor layer 2 under the oxidation resistant film 4 is subjected to thermal treatment. Hence a region, where the oxidation resistant film 4 of the non-single crystalline thin film semiconductor layer 2 being an active layer is not formed, is selectively oxidized; and in this part, a selective oxide layer 6 turning to an element isolation region is formed; at the same time, the non-single crystalline thin film layer 2 turning to the active layer under the oxidation resistant film 4 is subjected to solid growth in the simultaneous processing. In the above solid growth, the oxidation resistant film 4 acts as a capping layer, so that the forming process of capping layer can be omitted. Further, bird's beak phenomenon is controlled, and the selective oxide layer 6 free from bird's beak is formed.

Title: Lens holding mechanism
Inventor: MINEGISHI HITOSHI
IPC: G02B7/02
Filed: 1981-11-20
Abstract: PURPOSE:To prevent a variation of a radius of curvature, which is caused by expansion and contraction of a lens due to a temperature variation, by holding the lens through a member whose friction resistance is small. CONSTITUTION:On the inside of a lens barrel part 4 of a lens frame 2, an elastic deformation holding part 10 having prescribed elasticity in the diameter direction is provided. A ring-like friction attenuating member 9 provided with a flange 9a is formed by a material (teflon of mu=0.08-0.15 or so) whose friction coefficient is small, and is held by fitting the flange 9a into the elastic deformation holding part 10. A lens 7a is made abut to the friction attenuating member 9, and is held and fixed by screwing a holding ring 1 which has formed a screw part on its outside circumference, into a screw part 3 formed on the inside wall of the lens frame 2. The holding ring 11 is formed desirably by a material having a small friction coefficient which is same as that of the friction attenuating member 9. Expansion and contraction of the lens, which are caused by a temperature variation are absorbed by the friction attenuating member 9 and the holding ring 11.

Title: Liquid fuel combustion device
Inventor: KURIBAYASHI HISAYA
IPC: F23N1/00
Filed: 1995-06-29
Abstract: PURPOSE: To stabilize a combustion amount in a liquid combustion device such as a kerosene fan forced heater. CONSTITUTION: A liquid fuel combustion device feeds liquid fuel F in a liquid fuel tank A in a carburetor C by a pump B and a burner D to burn gasified fuel comprises a flame sensor 6 to detect conductivity of flame and output a signal responding to a combustion amount; and a pump drive control part to control a flow rate of the pump B by means of an output signal therefrom. This constitution prevents the occurrence of the mechanical change of a pump, and the change of a combustion amount occasioned by the increase of flow passage resistance due to accumulation of a solid in the fuel passage of the carburetor and stabilizes a combustion amount by controlling a flow rate of a pump. Further, since there is no need to individually regulate pumps, a manufacturing cost is reduced.

Title: Operation control method for copying machine
Inventor: SHIROSUGI KOJI
IPC: G03G21/06
Filed: 1990-07-13
Abstract: PURPOSE:To eliminate the waste of a transfer sheet caused by a miscopy by erasing a latent image on a photosensitive body with a latent image erasing means when the failure of the feeding of a document on an automatic document feeder is detected. CONSTITUTION:When the failure of the feeding of the document on the automatic document feeder 2 is detected by a detecting means 11, the latent image on the photosensitive body is erased by the latent image erasing means 25, so that even if the transfer sheet 3 is fed and carried to a developer part, an image is not transferred, but the transfer sheet 3 can be reused as a white paper. Therefore, the waste of the transfer sheet 3 caused by the miscopy can be eliminated. Especially, when the feeding of the transfer sheet precedes, the image can be transferred as the miscopy, but the latent image is surely erased to obtain a blank copy, so that the transfer sheet can be reused. On the other hand, a developing bias is also applied at the same time when the latent image is erased, and a developing potential can be increased, so that even if the latent image is left, toner is hardly stuck on the photosensitive body, and the blank copy can be more surely obtained.
