Title: Start control device of car with automatic transmission
Inventor: MATSUMORI YOSHIRO
IPC: B60W10/11
Filed: 1987-10-31
Abstract: PURPOSE:To prevent quick starting backward effectively by changing the start operation according to stamping of an accel. pedal between forward and backward conditions of an automatic transmission. CONSTITUTION:In case the car speed is smaller than the preset level, a controller 3 judges whether an automatic transmission 2 is in backward condition. In the case of backward condition, a lock solenoid 17 is actuated to protrude a lock pin 16 into a notch 15 of an accel. lever 14, and the amount of stamping of accel. pedal 10 is restricted to a certain extent. Even though the accel. pedal 10 is stamped once, no control of throttle valve 13 will be made to cause maintaining at the degree of opening for idling. When the output of an accel. stamping sensor 11 is put off and it is made sure that the accel. pedal 10 is returned, the lock solenoid 17 retracts the lock pin 16 from the notch 15 to admit stamping of the accel. pedal 10. This prevents surely unintended quick starting backward.

Title: Disk device
Inventor: MINAMI SHIGEO
IPC: G11B33/08
Filed: 1985-12-11
Abstract: PURPOSE:To prevent the occurrence of a resonance function by setting the disks at both ends of a spindle serving as the revolving center of a disk plate and providing a supplying device at a place near the disk to supply the air fluid in the radius direction of the disk. CONSTITUTION:The air stream lines 12 and 13 are produced on the outer diameter surface of a revolving disk 7 by an air fluid 8. The flowing speed of the line 12 is slowed down by the frictional force produced between the outer diameter surface of the disk 7 and the line 12 owing to a fact that the revolving direction of the disk 7 is opposite to the flowing direction of the air, on the contrary, the flowing speed of the stream line 13 is increased. The pressure of the fluid 8 is increased at the place near the disk 7 as the flowing speed of the fluid 8 is slowed down. Thus the pressure produced at the part of the line 13 is less than that produced at the part of the line 12. As a result, the force moving toward the line 13 is applied to the disk 7 and therefore the disk 7 is pressed by the fluid 8 in the set direction. Thus a spindle 3 is pressed to the set direction.

Abstract: PURPOSE:To reduce the disposal amount of sludge to a large extent by providing an inflow pipe, a spoilage chamber, a contact aeration chamber and an outflow pipe and arranging a plurality of the sludge sumps communicating with the inflow pipe formed by a screen member to the spoilage chamber in a freely changing-over state. CONSTITUTION:The sewage of garbage enters one of the sludge sumps 5 of a spoilage chamber 2 to be stored therein but, at the point of time when a certain amount of the sewage is stored, the sewage of garbage is allowed to flow in the other sludge sump 5 by a change-over cock 7. The accumulated substance in the sludge sump 5 putrefies. The liquid substance flowing out of the sludge sump 5 passes through the opening parts of a support shelf 8 to flow in a contact aeration chamber 3 through a flow transfer port 18. The flow transfer port does not issue sewage to the surface of the water of the contact aeration chamber 3 but communicates with the lower part of the contact aeration chamber 3 from the spoilage chamber 2 so as to allow the sewage to flow in a bottom surface. The sewage flowing in the contact aeration chamber 3 is decomposed and digested by aerobic bacteria deposited on a contact material 10. Subsequently, the sewage passes through the lower part of a recovery plate 11 to separate a solid component and exceeds an overflow weir 12 to be discharged as water of good quality from an outflow pipe 4.
