Title: Squeegee for printing cream solder
Inventor: SHIMAZU HIROSHI
IPC: B41F15/44
Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To provide a squeegee capable of enhancing the rolling properties of cream solder.

Title: Image forming device
Inventor: NAMIKI KAZUHIKO
IPC: G03G15/01
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of image quality caused by the fluctuation of the linear velocity of an image carrier caused by the contacting/separating action of a developer carrier by controlling the contacting/separating action of a contacting/separating member with/from the surface of the image carrier based on the contacting/separating action of the developer carrier. SOLUTION: A contacting/separating roller 19 capable of contacting with/ separating from the surface of a photoreceptor belt 1 is provided between the optical write-in position of the laying part of the belt 1 and the developing position of a developing device 5Y on the most upstream side. When the developing rollers 17 of all the developing devices 5 separate from the belt 1, the roller 19 comes in contact with the belt 1 by specified intruding amount. For example, when the actuation of BK is started and the developing roller 17BK of the developing device 5BK moves to the belt 1 side and starts to bite at the laying part of the belt 1, the roller 19 starts moving in a direction where it separates from the belt 1.  While the developing device 5BK and the roller 19 are moving, they are controlled so that the sum of the instruding amount of the roller 17BK and that of the roller 19 may be the specified amount.

Abstract: PROBLEM TO BE SOLVED: To obtain foods such as salad and sandwich using buckwheat sprouts having pharmacological effect such as blood vessel stabilizing action by culturing the sprouts efficiently, by immersing buckwheat seeds in water for a specified time followed by hydro-extraction and then treating the resultant seeds under specific conditions. SOLUTION: First, buckwheat seeds 11 are immersed in water for 10-12h and then hydro-extracted. Secondly, the resultant seeds 11 are spread at 3-7 counts/cm<2> all over the surface of a culture bed 21 consisting of a water- absorbable or water-permeable elastic material such as sponge, nylon net or need paper and placed on the bottom of a culture vessel 31. Thirdly, water is poured in the culture vessel 31 so that the water level H virtually coincides with upper face of the culture bed 21 and the culture vessel 31 is covered with a sheeting. Fourthly, when roots begin to grow from the seeds, the water level H is lowered so as to be 1-2cm above the bottom of the culture bed 21, and when the water is decreased in the culture vessel 31, water is replenished so as to recover to the lowered level H.  Afterwards, the water in the culture vessel 31 is renewed once every two days, thus conducting the objective culture of buckwheat sprouts.

Title: Ozone detector
Inventor: WATANABE KIYOSHI
IPC: G01N31/00
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To obtain a simple and inexpensive detector requiring no special component by a constitution wherein the status change of an ozone reactive means, composed of a substance having physical or chemical properties deteriorating easily upon reacting on ozone, is converted into an electric signal and detected. SOLUTION: An air gap part 5 is formed between the opposite protrusions of a casing 2A and a part of optical path, connecting between a light emitting diode 3 and a phototransistor 4, is formed in the air gap part 5. An ozone reactive substance susceptible to corrosion with ozone, i.e. a natural rubber band 6, is stretched while being applied with a specified tension between posts 11, 12 disposed symmetrically on the opposite sides of air gap part 5. When ozone leaks, the band 6 is corroded and eventually broken by tension and since the band 6 is removed from between the posts 11, 12, light emitted from the diode 3 impinged on the transistor 4. Consequently, the transistor 4 is turned on to feed a current through a resistor 8 and a microcomputer 9 delivers an abnormality detection signal for lighting an alarm lamp 10.

Title: Dynamic pressure type porous oil impregnated bearing unit
Inventor: MORI NATSUHIKO
IPC: F16C33/10
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To largely improve the durability service life by supporting a rotary shaft in a noncontact state by forming a dynamic pressure oil film of oil in bearing clearance by a dynamic pressure groove, and circulating the oil between the inside of a bearing main body and the bearing clearance through the opening hole part of the bearing surface. SOLUTION: A porous oil impregnated bearing 1 is constituted by impregnating lubricating oil or lubricating grease into a porous bearing main body 1a having the bearing surface 1b opposed to an outside diameter surface of a rotary shaft through bearing clearance. It is better to set density of the part containing the bearing surface 1b of the bearing main body 1a larger than density of the part containing an area 1d between the bearing surface. Since density of a porous body is related to porosity per the unit volume, a volume rate of a pore in a structure reduces as the density increases, so that the surface opening ratio in the surface reduces at the same time. Therefore, oil film strength in the bearing surface 1b can be improved, and bearing rigidity can be improved, so that durability can be improved by increasing the oil content in the area 1d at the same time.

Filed: 1999-12-09
Abstract: PROBLEM TO BE SOLVED: To provide a mechanism for measuring a color dispersion of an optical system which is not influenced by environmental effects, enabled to manufacture at low cost and constitution relatively simple with a remote access point. SOLUTION: A modulation signal 23 is generated at a local access point of an optical system 22, and a reference signal 33 is generated at a remote access point of the optical system. The modulation signal and reference signal are synchronized via a timing signal obtained from a GPS(global positioning system). The modulation signal modulates a light test signal with a predetermined light wavelength. A modulated light test signal 28 is impressed to the local access point of the optical system. The modulated light test signal is transmitted to the remote access point and demodulated. A time delay of a demodulated signal 29 to the reference signal is measured at the remote access point. A color dispersion of the optical system between the local and remote access points is measured from a relative delay by the optical system.

Filed: 1999-12-09
Abstract: PROBLEM TO BE SOLVED: To rapidly update product inventory and to prepare a shopping list of substituted items by adding purchased products to a present inventory list in response to input of an electronic receipt of purchased products, eliminating products from the present inventory list in response to electronic instruction of the codes of products to be disposed of, and comparing the present inventory list with a specified inventory level to indicate stock items in need of substitution. SOLUTION: Upon receiving an electronic receipt of purchased products (S100), a module judges whether all bar codes and brands exist in a correlative data base (S101). In case of not existing, the correlative data base is updated with new code/brand pairs (S102). According to the electronic receipt, a present inventory list is updated by an updating module with the bar codes and quantities of new items added to inventory (S103). When the receipt shows the purchase of a new item not existing in the present requested inventory list or the purchase of an existing item in larger quantity (S104), the requested inventory list is updated by the updating module (S105).

Abstract: PURPOSE:To transfer a mask pattern even on a large sized substrate with high precision by a method wherein the slippage of a mask pattern and position are measured so as to locally change the irradiating angle of exposure light according to the measured results. CONSTITUTION:A calibration mask is irradiated with the light emitted from an exposure optical part 6.
