Filed: 1988-12-21
Abstract: PURPOSE:To keep the grease feed quantity adequate and improve the reliability of the bearing rotation by lubricating the bearing of a high-speed rotation turbo- blower with grease and forming a grease reservoir section adjacently to the bearing. CONSTITUTION:A rolling element 28 is arranged between an inner ring 27 fixed to a shaft 26 and an outer ring 29 fixed to a bearing section to constitute a bearing 19. A grease reservoir section 32 is provided adjacently to this bearing 19, and an adequate quantity of grease 30 (30-50% of the space volume) is filled in the bearing. The grease of the inner ring 27 is scattered to the outer ring 29 and the grease reservoir section 32 by the centrifugal force via the high-speed rotation of the rolling element 28 and the inner ring 27, and the grease 30 and 31 is formed in a dike shape on both side faces of the groove of the outer ring 29 and the grease reservoir section by the gas stream due to rotation. The grease 31 of the reservoir section 32 gradually flows into the groove of the outer ring 29 by the viscosity and gravity, the scattered grease 30 is replenished, and the grease in the bearing is automatically kept at an adequate quantity.

Abstract: PURPOSE:To automatically control an air conditioner to start or end its operation according to whether a person falls asleep or rises by providing an existence judging means for judging whether or not the person is in a room in response to a signal from a human body detecting means, an activity amount judging means for judging the activity amount of the person in response thereto, a judging means for judging whether it is morning or night and control means for controlling an air conditioner according to the results of the morning or night judgements by the judging means. CONSTITUTION:Whether it is morning or night is judged by a morning and night judging means 23. When there is no activity of a person in a room at night, it is assumed by an assuming means 24 that the person is in a condition of sleep and a signal is sent to a control means 9. In the control means 9, a temperature resetting means 10 sets room temperature at a value the most suitable for sleep and an operation starting and ending means 11 brings the operation of an air conditioner to a stop after the lapse of a predetermined time. When the person starts his activity in the morning, a signal indicating his rising is sent from the assuming means 24 to the control means 9, whereby the temperature resetting means 10 resets room temperature at a value the most suitable for the daytime activity and whereby the operation starting and ending means 11 is so controlled as to start automatically the operation of the air conditioner.

Title: Constitution of slow line bypass in carbureter
Inventor: SASAKI YASUSHI
IPC: F02M19/06
Filed: 1988-12-23
Abstract: PURPOSE:To supply an adequate mixing ratios for accelerated/decelerated drivings and to improve an operability by forming a sub-bypass varying in the relative position with a throttle valve, beside a main bypass. CONSTITUTION:When a throttle valve 1 is at an idle opening, fuel is supplied from an idle nozzle 8 to an engine, measured by an adjust screw 6. The gap between the bore wall face 2 of a bore diameter and the throttle valve 1 is determined, corresponding to the opening F of the throttle valve 1. A sub-bypass 4 is formed at a location with an angle of deviation alpha as against a main bypass 3 and fuel supply, at a height to ensure the optimum fuel supply linkage with an adequate bore diameter. The mixing ratio lean zone in a slow main linking zone, constituting the main cause of shock in an acceleration/deceleration driving, can be eliminated, so that it becomes possible to give a mixing ratio stable and appropriate for an acceleration/deceleration driving and to improve operability.

Title: Transmission of engine
Inventor: KOBAYASHI MANABU
IPC: B60K17/06
Filed: 1989-12-15
Abstract: PURPOSE:To obtain a small transmission, suited for a high speed engine having a wide range of an operational speed, by providing a subtransmission between a crankshaft and a clutch means so that gear reduction ratio of the subtransmission is increased on the high speed side of the crankshaft. CONSTITUTION:A subtransmission 78 is placed on a high speed side, when a crankshaft 26 is in low speed rotation, and on a low speed side when the crankshaft 26 is in high speed rotation. Consequently, a range of fluctuation of an input speed of a torque converter 70 is decreased, and its efficiency can be improved and also preferable in the point of its durability. Also, a main transmission 76 is automatically speed-changed by changing the speed and the load of a vehicle, and if the main transmission and subtransmission 76, 78 are both switched by the speed and the load of the vehicle when the subtransmission 78 is placed on the low speed side, a multistep speed change equal to a product of numbers of speed change shifts of both transmissions 76, 78 is made possible. Consequently, reduction in size can be attained by decreasing a number of speed change steps of the main transmission 76.

Title: Electrodeless discharge lamp
Inventor: AKEBOSHI MINORU
IPC: H01J65/04
Filed: 1989-12-14
Abstract: PURPOSE:To suppress decay of a light flux by furnishing an induction coil for impression of high frequency output in contact with or in proximity or the outer or inner tube, allowing the discharge gas in the inner tube to discharge electricity through the action of a high frequency electric field induced around the induction coil with impression of the high frequency output. CONSTITUTION:When high frequency current is fed to an induction coil 7 from a high frequency power supply 6, an electromagnetic field is induced around the coil 7, and plasma discharge is induced of the inner tube 1. The ultraviolet rays generated with mercury excitation are passed through the inner tube 1 and emitted to reach the outer tube 2, and causes a fluorescent substance 3 to make light emission, which lights up the lamp. At this time, the inside of the outer tube 2 is kept at vacuum, so that the ultraviolet energy is transmitted to the fluorescent substance 3 effectively. The ionized discharge gas and/or electrons in the plasma, on the other hand, are encapsulated in the inner tube 1 and do not reach inside the diaphragm of the fluorescent substance 3, which should eliminate deterioration of the fluorescent substance due to ion bombardment and/or film surface deposition of blackened substance resulting from mercury. Thereby the light flux maintaining factor is enhanced.
