Title: Controller for floor heating device
Inventor: MORI KEIICHI
IPC: F24D15/00
Filed: 1989-10-30
Abstract: PURPOSE:To prevent a user from leaving a switch in a turned-on state and to enable a safe and long term use of a floor heating device to be attained by a method wherein when a signal of an operating switch is inputted while a timer counts a time, a forced stopping part for stopping a driving of the floor heating device is provided. CONSTITUTION:A forced stopping part is provided for stopping a driving of a floor device when a signal of an operating switch 9 is inputted while a timer 12 counts a time. In this case, when the timer part 12 outputs a signal to a timer driving part 13 for counting a time for a predetermined period of time, the timer driving part 13 may open a contact point and not transmit a signal of a floor heating device driving part 11 to a heater 7. In concurrent with this operation, a displaying of a display device 14 is also stopped. Accordingly, when a user once operates the operating switch 9 so as to start a floor heating operation, an electrical energization for the heater is automatically stopped after elapsing of a specified period of time. With such an arrangement, it is possible for a user to prevent a leaving the device in a turned-on state and then to perform a state operation for a long period of time.

Title: Automatic sound signal selecting device
Inventor: ISHIMARU AKIO
IPC: H04B7/15
Filed: 1986-11-28
Abstract: PURPOSE:To automatically attain the selection/switching of a sound signal with the highest quality by taking a notice of the corresponding of high-pass components included in the sound output signal of each receiver to the quality and detecting and comparing it. CONSTITUTION:The high-pass components of the sound signal are detected by a filter 2 equipped with a sound signal line 1 at the output of each receiver and converted into a DC voltage corresponding to the level of the detected signal by an amplifier 3 and a rectifier 4. A comparator 5 is driven by the DC voltage to compare and select the quality and forms a switching pulse corresponding to the level of the detection signal. The switching pulse controls a photocoupler 6 mounted to each sound signal line 1. Then a dry battery 6 supplies the DC current. Since the signal is selected and switched momentarily automatically corresponding to the rapid change in the sound output signal, the sound output signal with the high definition is always ensured.

IPC: A45C13/30
Filed: 1990-10-24
Abstract: PURPOSE:To make it possible to assemble a bag by providing on both ends of hanging thread a piece for inhibiting the pull-out of a thread having a lateral width that can pass through a thread orifice by directing the piece along the thread body, said piece having a length larger than the diameter of the thread orifice. CONSTITUTION:To each of ends of the main body of the thread having a predetermined length the intermediate portion of one external surface of a oblong synthetic resin plate 2 having a L-like cross section is attached and bonded in such a manner that the other external surface faces the inner center with respect to the thread body. This thread body is either soft or has a flexibility that enables the bending of the thread body by pressing in the longitudinal direction of synthetic resin plate. Such bending allows the thread to penetrate the thread orifice of a paper bag along with the synthetic resin along the direction. By relieving the pressure-bending to return to the crossed state, the synthetic resin plate is cannot be pulled out to constitute a piece for inhibiting the pull-out of a thread 3. The preliminary length of this piece 3 is made larger than the diameter of the thread orifice. The other outside, that is not bonded, of the synthetic resin plate provide a reinforcing edge 2.
