Title: Manufacture of bearing
Inventor: MIYASAKA MOTOHIRO
IPC: B22F5/12
Filed: 1999-08-24
Abstract: PROBLEM TO BE SOLVED: To efficiently manufacture a bearing of two-point support structure with a sintered body built in a housing and having excellent bearing performance in a relatively simple method. SOLUTION: This manufacturing method comprises a disposing process in which a stock (a sintered body) 1A to be formed in a bearing body 10A is concentrically press-fitted in a housing 21 and disposed and the stock and the housing are temporarily integrated, and a press-fitting process in which the housing 21 is press-fitted into a forming hole 30 in a die 31 together with the stock 1A in a condition where a core rod 32 having a large diameter part 32b for forming a dynamic pressure groove is inserted into the stock 1A. In the press-fitting process, the housing 21 is contracted over the whole length, and the outside diameter surface of the stock 1A is pressed against the inside diameter surface of the housing 21.  The inside diameter surface of the stock 1A is pressed against the core rod 32 through the diameter contraction of the housing 21, and an inner relief part 13 and a pivotably supported surface 12 are formed by the large diameter part 32b and the core rod body part 32a of the core rod 32, respectively.

IPC: F04B39/12
Filed: 1987-09-21
Abstract: PURPOSE:To suppress the resonance of a container without largely changing the appearance and size of the container by providing the enclosed container with curved surfaces formed with circular arcs having the center angle of 50 deg. or more against circular arcs to other adjacent curved surfaces. CONSTITUTION:The enclosed container 5 of a compressor is formed with a continuous body of curved surfaces, and an inflection point 13 is provided at the connection section between a curved surface 6 and a curved surface 7. The curved surface 6 is formed with a circular arc 10 for the center angle 12 of a radius r1 centering a center point P, and the curved surface 7 is formed with a circular arc 11 for a radius r2 centering a center point Q. The circular arc 10 has the center angle of 50 deg. or more, and the node of its natural mode exists on the inside of the inflection point 13. The natural frequency of the circular arc 10 is thereby very high, and as a result the curved surface 6 with high rigidity is formed, and a compressor with low noise can be set.

Title: Toner container for electrophotographic device
Inventor: OKA SEIJI
IPC: B65D83/06
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To obtain a toner container in which the removal of toner sticking to the shoulder of a container main body is easy when it is washed by an air wash method by specifying a ratio between the diameter of a toner discharge opening and the diameter of the container main body. SOLUTION: A helical projection 4 is formed on the inner circumferential surface of the container main body 2, and by rotating the toner container 1 around its axial line, toner stored in the toner container 1 is sent out to the toner discharge opening 3 along the helical projection 4. Because the toner discharge opening 3 is situated in the middle of the container main body 2 and its diameter is smaller than that of the container main body 2, the toner is ejected by being lifted to the toner discharge opening 3. For the reason, two shoulders 5 are provided near the toner discharge opening 3 of the container main body 2, and a pushing-out part for lifting the toner is formed between the large-diameter part of the container main body 2 and the shoulders 5.  Therefore, the diameter of the container main body 2 is set larger than the diameter of the toner discharge opening 3, and the diameter of the container main body 2 is set four or less times smaller than the diameter of the toner discharge opening 3.

Title: Pump device
Inventor: KAAI MASAFUMI
IPC: F04C14/00
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To provide a pump device capable of maintaining a pulsation- preventing function for a long time period. SOLUTION: In a pump device, a diaphragm 200 made of a rubber and closing a communication passage 110 connecting a gas separation device 60 and a fluid discharge passage 30 is provided. When a pulsation is generated in the fluid discharge passage 30, the diaphragm 200 receives the pulsation and is deflected and deformed and the pulsation is absorbed by the deformation. Therefore, it is inhibited that the pulsation is transmitted to a gas/liquid separation device 31 provided at a latter stage of a pump 19, a filter 41 a flow meter connected to a discharge opening 12, a nozzle, etc., and a generation of an erroneous operation caused by the pulsation of these connection members.  Even if a hole is tentatively generated on the diaphragm due to a secular deterioration, since the pulsation is absorbed by the deflection and deformation of a whole surface of the diaphragm 200, a pulsation-preventing function is not immediately lost and the pulsation-preventing function can be exhibited for a long time period.

Filed: 1995-09-18
Abstract: PROBLEM TO BE SOLVED: To force a train to stop without giving any uncomfortable feeling to passengers or disturbing their transfer to an alternate transport means, when the train is obliged to stop in emergency. SOLUTION: When the stoppage of preceding train is not caused by any emergency apparently, a stoppage target position is set on the basis of the minimum safety margin distance SM (S40). When it can not be judged as a normal stoppage, the stoppage possible distance at the maximum running speed Dmax is calculated so as to set SM-Dmax as a stoppage allowable range (S50-S90). If any station or retreat place is present within a stoppage possible range, that position is set to a stoppage target position (S120). Or the stoppage target position is set to avoid any railway crossing or a tunnel (S150). If such a station and/or a funnel, etc., are not present, Dmax is set to a stoppage target position (S160).  When the stoppage target position can be set in this way, the speed limiting curve of the following train is formed to obtain zero speed at this position (S170) so as to transmit this information to the following train (S180).
