Title: Horizontal gear type grease sealing gas compressor
Inventor: YOKOI KOUMEI
IPC: F04C29/02
Filed: 1982-04-14
Abstract: PURPOSE:To permit a thick sealing effect and a separating effect by a method wherein a grease separating chamber is constituted by a part of a casing to miniaturize it and the perticle of the grease mixed with compressed gas in the grease separating chamber is separated and retrieved to supply it to a gear rotor. CONSTITUTION:The grease separating chamber 5 is constituted by a part of the horizontal casing 2 to miniaturize it. The perticle of grease, mixed with the compressed gas, is pushed out from the upper opening 4 of the casing into the separating chamber 5, however, the molecular weight of the grease G is larger and, therefore, the grease is separated from the gaseous body, the speed of which is attenuated in the separating chamber 5, dropped onto a block of the grease G on a grease pan 11 to retrieve it, the surface part thereof is softened by the temperature of the compressed gas again and is supplied from both blades 14, 14' to the peripheral surfaces of the gear rotors 9, 9' under a dropping condition to seal the gap S between the gear rotors 9, 9' and the casing 2 by the grease sealing. Thus, the thick sealing effect and the separating effect may be permitted by the circulation of the grease G and the grease sealing.

IPC: H04W88/02
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To remarkably improve a security function while satisfying a specification common for all makers/entrepreneurs. SOLUTION: A key input timing monitoring part 10 monitors the key input timing of a personal identification(PIN) number inputted from a key operating part 60 and reports the key input timing of the inputted PIN number to a PIN number collating and judging part 12.

IPC: G06T5/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To obtain an image with sharpness emphasized from an edge part and an image with good image quality, such as suppression of granularity from a granularity area by sharpening granularity noise included in an image, separating the edge part and flat parts of the image, detecting a granular signal from the flat part which is regarded as the granular area, dividing the granular part into small divisions and selectively eliminating them.

Title: Ventilated propeller apparatus
Inventor: OZAKI ATSUSHI
IPC: B63H1/18
Filed: 1979-05-22
Abstract: PURPOSE: To prevent cavitation, in crease the efficiency and eliminate fluctuation of thrust and torque by opening to the atmosphere a rear surface of a propeller in an advancing condition, and allowing the whole front surface of the propeller to hit water.  
     CONSTITUTION: Water is introduced to a duct 3 from a water inlet 2 which is installed, to protrude downward from a bottom 1 of a boat. Thus, the whole front surface of a propeller 5 disposed at an outlet of the end of the said duct 3, hits water. When a high speed boat slides by driving the propeller 5, a water surface 7 behind the boat becomes lower than the propeller 5, and the rear side of the propeller is thoroughly exposed in the atmosphere. In this manner, air is inhaled to  the rear side of the propeller 5 and a cavity is formed. So the behavior of the propeller of this invention is quite same as the surface propeller. The water in the duct 3 collides with the whole front surface of the propeller 5. Consequently the thrust and torgue becomes twice as high as those for the surface propeller, and these are hardly fluctuated. The pressure in the cavity is approximately equal to the atmospheric pressure, therefore, no cavitation is caused.

Abstract: PROBLEM TO BE SOLVED: To eliminate influence by azimuth angle and refractive index of mold glass on the gap depth measurement by observation and measurement with an azimuth recording magnetic head inclined in the angle adding a corrected angle, considering the azimuth angle and refractive index of mold glass. SOLUTION: In the case of easily and accurately measuring a gap depth by eliminating an influence of azimuth angle θ, the refractive index of mold glass 30 must be considered and therefore it is enough to obtain the angle θi (incident angle in which the angle θr becomes the azimuth angle θ and the gap depth observing direction 32 which is inclined by the angle θi from the direction 31 perpendicular to the side surface of the C core 26 and I core 27. The gap depth observing direction 32 (incident angle θi) considering the azimuth angle θ and refractive index of the mold glass 30 is observed in the direction not parallel to the gap surface 28 at the outside of the azimuth recording magnetic head but in the direction parallel to the gap surface 28 in the inside of head.

Title: Plasma torch for heating molten steel in tandish
Inventor: SAIKI MASAKI
IPC: B22D41/015
Filed: 1991-03-27
Abstract: PURPOSE:To improve the distance accuracy of arc length by detecting the surface of molten metal of molten steel by measuring weight of a tandish, and moving vertically a plasma torch at the time of deviating from the upper and the lower limit values of control dead zone width of the set arc length. CONSTITUTION:Total weight of a tandish 1 and received molten steel 4 is measured by a weight detector 21, and height of the surface of molten metal of the molten steel 4 is calculated by a molten metal surface converter 25. A torch position detector 21 calculates a position of a torch 9, a computing element 26 calculates arc length from its position and molten metal surface height data, and when a difference from the set arc length exceeds control dead zone width, a torch ascending/descending mechanism 18 is driven, and it is set to prescribed arc length. Since a control dead zone exists, actuation frequency of the torch ascending/descending mechanism 18 decreases and a useful life period is prolonged, and also, the distance accuracy of arc length is improved.

IPC: H04L29/12
Filed: 1995-03-22
Abstract: PURPOSE: To provide a terminal equipment for ISDN capable of inexpensively transmitting short and simple information to an opposite side. CONSTITUTION: A storage part 5 stores a communication message in accordance with a sub address. In such a state, an interface part 1 receives a call setting message on a transmission side via an ISDN line 10. When the interface part 1 receives the call setting message, a control part 2 checks whether or not the communication message in accordance with the sub address exists in the call setting message in the storage part 5. When the communication message exists, the control part 2 displays the communication message in accordance with the sub address from the transmission side on a display part 3, and also, sends a call message to the transmission side. In such processing, a reception side only receives the call setting message and transmits the calling message to the transmission side. Therefore, no charge for the ISDN line 10 is applied to the transmission side.
