Title: Sealed type roller bearing
Inventor: MATSUOKA SHOJI
IPC: F16C19/22
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To prevent one side wear on an outer ring raceway and a roller rolling contact surface, and outer leakage of sealed grease. SOLUTION: A case-engaging recessed part 5 is formed at both ends of an outer ring 1 installing double row tapered roller 4 between the outer ring and an inner ring. A fitting cylinder part 8 is provided to the end of a sealing case 7 holding a sealing 10 for preventing invasion of dust into the bearing. The fitting cylinder part 8 is engaged with the case-engaging recessed part 5. A rib 9 provided at the outside diameter face end of the fitting cylinder part 8 is engaged with an engaging groove 6 formed in the case-engaging recessed part 5 at its inside diameter face to anti-release the sealing case 7. Elastic deformation afforded by a elastic body layer 12 anchored to the fitting cylinder part 8 at its outside diameter face prevents the outer ring 1 at its both ends from deformation in the outside diameter direction.

Title: Cage for poultry house
Inventor: HIRAMA HIDEMICHI
IPC: A01K31/16
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To remarkably reduce a ratio to occur defect in egg. SOLUTION: A region E constituted so as to facilitate ready rolling of hen's egg is formed in a part directly before an egg-saving wire when viewed from the deep side of a cage bottom 4A to the direction of this side in a cage for poultry house, Thereby, even if hen's egg 23a comes into contact with an egg same wire 9 in longitudinal state to the wire 9 after the egg is sprung up and rolled on the cage bottom 4A and been out therefrom, the egg 23a is further rolled and kept in stable lengthwise state. As a result, a ratio of hen's egg which is kept in longitudinally engaged state to the wire 9 is finally remarkably decreased.  Since the horizontal engaged hen's egg is put on the cage bottom 4A in readily rollable state to the longitudinal direction and the egg is immediately dropped in an egg-gathering part 6 by raising the egg saving wire 9, the egg does not strongly collide with the next hen's egg which is laid in the cage and the incidence of defect causing breakage or crack is also remarkably decreased.

This detector generates only a transient output signal in response to the existence of dust even at the time of being exposed to a dust environment. It is because intervals mutually between dust particles are larger than the size of a light beam 30-3. Then the controller, etc., includes a microprocessor 14 and a control program and processes a signal waveform received from a sensor 30 in order to remove a non-fire signal generating a prescribed waveform.

Abstract: PROBLEM TO BE SOLVED: To suppress the deviation of an air-fuel ratio of combustion air-fuel mixture from a target air-fuel ratio by changing a purge air amount in delay for the change of a suctioned air amount of an engine in accordance with the change of load of an auxiliary machinery. SOLUTION: At the time of turning OFF of load of an auxiliary machinery from ON when the delay in the reduction of a purge air amount occurs (S5 to S6), a correction coefficient K1 is set in such a way that an opening degree control amount (duty) of a purge control valve is set to zero once and then is returned to a normal value gradually (S7). On the other hand, at the time of turning ON of load of the auxiliary machinery from OFF when the delay in increase of a purge air amount occurs (S5 to S11), a correction coefficient K2 is set in such a way that an opening degree control amount (duty) of the purge control valve is stepwise increased and then is returned to the normal value gradually (S12). A basic value of the opening degree control amount (duty) set in accordance with a suctioned air amount of an engine is compensated by the correction coefficients K1, K2 (S17).

Filed: 1991-12-10
Abstract: PURPOSE:To allow a monitor to cope with both a general-purpose subscriber circuit and a general-purpose analog trunk of an exchange by selecting other method so as to restart an exchange system when a reply from the exchange system is not normal. CONSTITUTION:A control circuit (CTL) 4 drives an LP relay and an S relay of an interface section 19 to set a resistance between external lines R, T to be low (loop state) and sends a loop start signal to a subscriber circuit of an exchange system. Then the control circuit 4 recognizes a state of a dial tone from the exchange system based on an output of a digital signal processor(DSP) 1 to confirm the normality of the operation of the exchange system through the subscriber circuit. A switch circuit 6 designates a frequency and a level of a dial tone detected by the DSP1. When the normality of the exchange system operation is not confirmed, the control circuit 4 drives the S relay and sends an earth level only to the line R to confirm the normality of the exchange system via an analog trunk.
