Title: Bearing structure for rotary shaft and electric motor
Inventor: HARADA YOSHIHIKO
IPC: F16C19/12
Filed: 2001-04-20
Abstract: PROBLEM TO BE SOLVED: To provide a bearing structure for a rotary shaft and an electric motor having the bearing structure for the rotary shaft applied thereto, providing easy and inexpensive manufacturing and assembly of components and capable of securing predetermined durability in a state properly corresponding to a thrust load without enlarging a diameter of the rotary shaft. SOLUTION: In a geared motor, a radial load of an armature shaft 16 is supported by a metal ring 20 and its thrust load is supported by a thrust ball 32 held in a holding hole 24. Since an inner diameter of the holding hole 24 is larger than a diameter of the armature shaft 16, a diameter of the thrust ball 32 can be enlarged in correspondence to the thrust load irrelevantly to a diameter size of the armature shaft 16 and the predetermined durability can be secured. Since there is no need to provide a holding part of the thrust ball 32 in a tip of the armature shaft 16, manufacturing and assembly is easy and inexpensive.

Title: Deterioration evaluating method of lubricating oil for internal combustion engine and replacement timing detecting device
Inventor: SUMI KENZO
IPC: F01M11/10
Filed: 2001-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a deterioration evaluating method of lubricating oil for internal combustion engine which can evaluate the degree of deterioration of lubricating oil in the internal combustion engine with a simple method with accuracy and a replacement timing detecting device of lubricating oil for the internal combustion engine which can accurately detect replacement timing of the lubricating oil based on the evaluating method. SOLUTION: A temperature range where lubricating oil for an internal combustion engine is used is divided into two of a low temperature and a high temperature at a predetermined border temperature. According to an operating time of the internal combustion engine and the temperature of the lubricating oil at that time, the operating time weighted respectively in each of the temperature ranges is sequentially subtracted from remaining usable time for the lubricating oil. The operating time at the low temperature is integrated in advance, and the integrated value weighted at state transition to the high temperature is further subtracted from the remaining usable time. When the remaining subtracted usable time for the lubricating oil becomes negative in this way, an alarm lamp is turned on to notify it to a user.

Title: Optical sensor and inspecting method therefor
Inventor: OMI TOSHIHIKO
IPC: H04N5/357
Filed: 2001-04-23
Abstract: PROBLEM TO BE SOLVED: To provide an optical sensor in which the variation of the sensitivity of pixels for each pixel is suppressed. SOLUTION: The optical sensor composed of a semiconductor photoreceptor element has an area, in which an impurity having a polarity which is different from that of a semiconductor substrate is diffused in its scribe. By causing the potential at the area where the impurity is diffused to float, the charges generated by the light made incident to the scribe of the sensor can be stored efficiently in the P-N junction, constituted of the area containing the diffused dopant and semiconductor substrate. Consequently, the charges generated by the light made incident to the scribe will not reach the P-N junctions which constitute the pixels of the sensor.

Title: Game machine
Inventor: FUKUDA SADAO
IPC: A63F5/04
Filed: 2001-05-01
Abstract: PROBLEM TO BE SOLVED: To provide a game machine which prevents a player from hardly predicting accumulated time of a game and specifying time of generating a special game to enable a player to get rid of losing interest to guess time to stop a game. SOLUTION: Game time is accumulated by a control part 23 (step 304) and an update stop request is flagged (step 202) when the accumulated time exceeds 7200 seconds. However, when no medal is thrown in (step 403) within 30 seconds after all reels 4-6 stop, an update stop request is flagged (step 405) to temporarily stop to update accumulated game time. Thus accumulated game time is not settled but controlled by a game pace of a player causing accumulated game time is hardly predicted and generating time of a special game is hardly specified by a player. As a result, a player can get rid of losing interest to guess time to stop a game.
