Title: Hot water supply equipment
Inventor: TANAKA YOSHIHIKO
IPC: F24H1/10
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of a chattering phenomenon by holding a burner in a standby state for a prescribed period even when the sum of a feed forward control value and a feedback control value is restored to a second reference value or more in the case when the sum becomes a first reference value or less and combustion of the burner is once turned OFF. SOLUTION: In case when a hot water supply operation and a bath reheating operation are conducted simultaneously, a control part 70 starts a continuous combustion operation by an FF control and an FB control. It monitors whether or not the sum of an FF heated water supply number being an FF control value and an FB heated water supply number being an FB control value becomes a first reference value or less, and when the sum becomes this value or less, it turns combustion of a burner 12 OFF and puts the burner in a standby state. It monitors restoration of the sum of the FF control value and the FB control value to a second reference value or more after the standby state is maintained with the combustion stopped necessarily for a prescribed period, and when the sum is restored to the second reference value, it restarts the combustion of the burner 12. According to this constitution, the burner can be prevented from turning ON and OFF in a chattering manner.

Title: Door lock mechanism
Inventor: ISOGAI YOSHINOBU
IPC: G11B33/02
Filed: 1992-08-07
Abstract: PURPOSE:To unlock door automatically when a cassette tape is rejected. CONSTITUTION:When a VTR body 7 begins to reject a cassette tape 6, a cassette door 3 interlocked with a cassette tape carrying mechanism rotates to the inside of the VTR body around the upper end part thereof. Consequently, a magnetized member 5 carried on the cassette door 3 separates from a locking magnet 4 to deprive holding force from a magnet lock mechanism to allow gravitational rotation of the door around a bearing part 2 located at a lower edge part upto an open-door position. Since opening operation of the door 1 begins before the cassette tape 6 projects from the VTR body, collision of the cassette tape 6 and the door can be avoided.
