Title: Scroll compressor
Inventor: TAKASE HIRONORI
IPC: F04C29/02
Filed: 1998-12-01
Abstract: PROBLEM TO BE SOLVED: To reduce an oil rise quantity by excellently separating oil contained in compressed refrigerant gas, by oppositely arranging at least a single colliding plate to an inner wall peripheral directional outlet part of a sealed vessel, and arranging a stream lining plate for checking a flow of refrigerant gas to an electric motor upper chamber in an upper end part of the colliding plate. SOLUTION: A gas guiding passage frame 14 is provided with a sealed vessel inner wall peripheral directional outlet part 14a opening in the inner wall peripheral direction of a sealed vessel 1 in a position lower than a coil end upper end surface and a second passage directional outlet part 14b opening in the direction of a stator side surface second passage. At least a single colliding plate 14c is oppositely arranged to a sealed vessel inner wall peripheral directional outlet part 14a. A stream lining plate 14d is arranged in an upper end part of the colliding plate 14c. Refrigerant gas flowing out of the sealed vessel inner wall peripheral directional outlet part 14a directly collides with the colliding plate 14c to separate oil containined in the refrigerant gas.  A more remarkable oil rise preventive effect can be obtained without scattering the oil separated by the colliding plate 14c in the direction of a compressor part.

Title: Optical recording method and optical recording device
Inventor: ISHII KOICHIRO
IPC: G11B11/10
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To perform recordings suited to individual mediums by setting the light intensity at the time of recording to the value being within a permitted limit width at the time of a test recording and also by not resetting based on a light intensity equivalent to the temp. change of a record medium when the permitted limit width is >= a prescribed width. SOLUTION: Test recording and reproducing of reference data are performed three times in the prescribed area of an optical disk 10 by changing recording powers and the number of errors is counted by comparing reproduced data and reference data to be stored in a memory 15. The center value of a recording power in which the number of errors becomes <= the number of permitted errors is set in an LD driving circuit as a normal recording power. Here, when the permitted limit width of the recording power is wider than a prescribed width, the resetting posterior to the loading of the optical disk 10 is unnecessitated and it is not performed.  Thus, the degrading of a record medium and the lowering of the performance of a recording device are prevented by reducing the number of testing times while a resetting process is not performed as to a disk which does not have necessity of the setting of a recording power and by performing the resetting of the recording power even as to an optical disk which has necessity of the resetting of the recording power only when necessity is generated by a temp. change or the like.

Title: Method for preventing emergence of weed in paddy field
Inventor: NISHIFUJI HIDEO
IPC: A01M21/00
Filed: 1999-10-25
Abstract: PROBLEM TO BE SOLVED: To produce organic agricultural crops with saved labors at a low cost without using a herbicide and agrochemicals for controlling pests. SOLUTION: Substances called saponins of glycosides are contained in a part of plants. The kinds and contents of the saponins depend on the kinds of the plants and on the parts of the plant bodies. Since a large amount of a saponin is contained in camellia oil-extracted residues, the camellia oil- extracted residues are scattered on a paddy field, after rice seedlings are planted in the paddy field. The generation of weeds can thus be prevented by the action of the saponin.

Abstract: PURPOSE:To realize a metallic thin film type magnetic recording medium having no abnormal projection which does not damage the surface of a magnetic head by treating the surface of the metal thin film type magnetic recording medium forming a protective film having >=2,500 kg/mm<2> Knoop hardness on a magnetic layer by burnishing. CONSTITUTION:A Co-Ni alloy is vapor deposited on a PET film, on which several protective layers of different hardness are formed. This film is then coated with a lubricant and then subjected to burnishing. The burnishing is performed by pressing the magnetic surface of the vapor deposited tape 3 with a polishing tape 7 which is wound on a drum while the vapor deposited tape 3 is travelling, and sending and sliding the polishing tape 7 in the opposite direction of the tape 3. When the Knoop hardness of the protective films is >=2,500 kg/mm<2>, the number of dropouts where recording signals are omitted can be largely reduced by burnishing, and the effect of burnishing is remarkable.

Title: Transfer controller for image forming device
Inventor: KAWABATA TAKASHI
IPC: G03G15/16
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To set a proper transfer condition, without being affected by the change in resistance of a transfer material and an environmental condition and to easily make image quality high after a transfer is performed, without decrease in productivity by measuring the resultant resistance of a transfer area at the time when the transfers material enters into transfer area and controlling the transfer condition, based on the measured resultant resistance in the transfer area. SOLUTION: A transfer area resistance measuring means 4 measures the resultant resistance of the transfer area at the time when the transfer material 3 enters into the transfer area by a transfer means 2. A transfer condition control means 5 controls the transfer condition of the transfer means 2, based on the measured resultant resistance of the transfer area. In such a transfer condition control process, the resultant resistance in the transfer area by the transfer means 2 is one accurately measured by the transfer area resistance measuring means 4, so that the resultant resistance directly reflects the change in the resistance of the transfer material 3 and the fluctuation of the environmental condition. Thus, the transfer condition controlled on the basis of the resultant resistance is set as a more optimum one by the reflection.
