Title: Opening/closing lid structure for recorded medium inserting section
Inventor: TANAKA TETSUYA
IPC: G11B33/02
Filed: 1992-12-28
Abstract: PURPOSE:To provide a hop-up mechanism occupying only a small space with a simple constitution by providing an elastic member between the outer and inner lids on the recorded medium inserting section. CONSTITUTION:A compression coil spring 23 is provided between the outer lid 20 and the inner lid 21 in the vicinity of a hinge section 7. Dependent upon the opening condition of an opening/closing lid 6, the edge part of the inner lid 21 is raised by a specified amount over the outer lid 20 by the force of the spring 23. When the opening/closing lid is closed, the inner lid 21 as a gasket is stuck to a place around the inserting port 5 of a front panel 3, the edge part of the inner lid 21 is pulled in against the force of the spring 23 and completely closed and locked. Then, when a locking plate 8 is removed, the opening/ closing lid 6 is opened up to an angle where it is easy to put a hand like automatically jumping and then, it becomes easy to open it rotating it by hand. Thus, the existence of dead spaces is eliminated and a player is made compact.

Title: Quantitative pump apparatus for combination treatment purification tank
Inventor: NAKADA MAKOTO
IPC: F04B49/06
Filed: 1995-11-12
Abstract: PROBLEM TO BE SOLVED: To reduce the variation in the amount water sent from a discharge tank of the final stage and enable judgement of total amount of water to be treated at a glance by installing a set value shifting mechanism which decreases (increases) the number of revolution of a pump motor when a water level of a tank is high (low) and changes the amount of water to be sent of a pump. SOLUTION: When the water level of a tank equipped with a submergible motor pump is high due to a large amount of water to be treated introduced from a tank of a preceding stage, electric signals are sent from a pressure sensor 6 and a revolution sensor 7 to a control circuit part 3, and a power source which decreases the number of revolution of a pump motor 2 to respond to a pump head at the level reduces the rotation speed of the submergible motor pump. When the water level of the tank equipped with the submergible motor pump is low due to a small amount of water to be treated from the tank of the preceding stage, the power source which increases the number of revolution of the pump motor 2 increases the rotation speed of the submergible motor pump, reducing the variation in the mount of water to be sent associated with the change in the water level.  When the quantity of water is required to change, a set value shifting mechanism 8 is operated to change a set water amount.
