Title: Flywheel type energy reserving device
Inventor: TAKAHASHI ISAO
IPC: F16F15/30
Filed: 1987-12-25
Abstract: PURPOSE:To improve the reliability of the device as well as to reduce the cost by providing a circular plate made of high tension material and a flywheel where winding member is wound up in polygon in conformity to supporting members. CONSTITUTION:A ring shaped circular plate 34 is made of high tension material. Piano wire supports 35 are arranged on outer peripheral portions of the circular plate 34 at equal interval. Binders 36 for binding piano wires are made of fiber- like members and arranged in plural numbers on the outer peripheral portion of the circular plate 34. Piano wires 37 of winding member are wound along the outer periphery of piano wire supports 35 and the circular plate 34.

Title: Hot air heater
Inventor: MESAKI MICHIO
IPC: F24H3/04
Filed: 1989-12-21
Abstract: PURPOSE:To permit a fan forced heater to be operated only when it gets much colder than expected in a weather-changeable season with a convenient and economical handling by operating a combustion means of the heater only wen the temperature of a room detected at a set ignition time is lower than a set temperature. CONSTITUTION:To set a 'good morning' timer 7e for desired ignition time, current and ignition times are set and stored in a control part 11, an operation switch 7a is then depressed and a 'good morning' timer switch 7e is thereafter depressed. When the set ignition time comes, a fan forced heater is actuated to release the timer 7e, if the interior temperature of a room is higher than a set temperature, when the set temperature displayed by a set temperature indicator 6d at an indication part is compared with the interior room temperature detected by a room temperature sensor and displayed by a room temperature indicator 6e and, if the interior room temperature is lower than the set temperature, the heater starts the heating operation. In this way the heating operation is started only when the room temperature at the set ignition time is lower than the set temperature, even if the timer 7e is set for the desired ignition time.
