IPC: F24D11/00
Filed: 1984-08-29
Abstract: PURPOSE:To provide a heat accumulation type floor heating system that can maintain the floor temperature at a desireable temperature during the heat accumulation and heat release by setting the thermal conductivity of a protective layer installed on a latent heat accumulating means which is constructed by sealing the latent heat accumulating material in a container made of film lower than that of the sensible heat accumulation material formed on top of the protective layer. CONSTITUTION:A bag container 4 made of polyethelene film containing a latent heat accumulation material 3 comprising Na2SO4.10H2O and a rubber sheet 5 as a protective layer are sequentially placed on top of a heat generating body 2, and mortar 6 is set on top of them, which becomes a heat accumulating body after being dried. The film container 4 containing the heat accumulating material 3 can be sealed by heat, facilitating the containment work. By setting mortar or concrete after fixing in place by the protective layer made of elastic material such as rubber sheet, the damage to the container can be prevented. As the rubber sheet 5 has a thermal conductivity one figure lower than mortar or concrete, a thermal loss from the surface of the heat accumulating body can be prevented.

Title: Stop controller of central processor
Inventor: NISHIMURA GENICHI
IPC: G06F11/36
Filed: 1980-12-19

Patent JP-S6242176-A (JP)
Title: Copying device
Inventor: MIYAGI TAKESHI
IPC: G03G15/20
Filed: 1985-08-20
Abstract: PURPOSE:To obtain a clean copy image without causing the input voltage of a lighting device to vary owing to voltage loss of heater electric power by fixing the heating operation state of heat fixation while an original is scanned and read. CONSTITUTION:When copying operation is started, a heater 51 is powered on continuously and the temperature rises gradually; and an output HC changes to '1' at some point above set temperature, but a CPU 56 disregards that. Copying paper passes through a fixing device 35 in copying operation, so the paper absorbs heat and a heat roller 33 does not rise in temperature abnormally. The heater 51 is turned off on a return way and the surface temperature of the roller 33 drops, but the scanning speed in a forward movement section is, for example, 180mm/sec and it takes 420/180(sec), i.e. a short time for an original of A3 scanning width size, so that the surface temperature of the roller 33 does not falls abruptly because of the heat capacity of a fixing roller 33. A signal VSYNC is '0' when the machine is not in copying operation, so the heater 51 is turned on the off according to the output level variation of the signal HC to control the temperature at any time.

Title: Button type alkaline primary battery
Inventor: MURAMATSU YUKIO
IPC: H01M4/06
Filed: 1983-09-28
Abstract: PURPOSE:To increase weighing accuracy, prevent generation of break or crack of negative active material during battery assembly, and uniform battery capacity by using a copper-based Cu-Zn clad plate having lath-shaped surface as negative active material. CONSTITUTION:Thickness of copper of a copper-based Cu-Zn clad plate 8 which constitutes a negative electrode is preferably limited to 5-50% of the total thickness of the plate. Since copper of the base material is used to prevent generation of break or crack of zinc which becomes brittle after punching and amalgamation, the thickness of a minimum of 5% of the total thickness is necessary for this purpose. The thickness of 50% or more of the total thickness is not preferable because the amount of zinc which serves as negative active material is decreased.

Title: Image processor and image forming method
Inventor: HAMANO SHIGEMICHI
IPC: G03G21/14
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To restrain the increase of power consumption in an entire device by providing a means for controlling either of two heaters so as to be energized from transferring one image to an intermediate transfer body till transferring the next image. SOLUTION: When the first time scanning of an original is finished, a reader controller 106 makes a fixing heater control signal/STOPHEAT signal to a low level so that a one-side fixing heater should be made to be in an unenergized state for an engine control part 2002. When the signal becomes at the low level, the control part 2002 controls the fixing heaters inside a fixing roller and a pressure roller so as not to be turned on simultaneously. By controlling either fixing heater inside the fixing roller or the pressure roller so as not to be energized between the images from the controller 106 side, the power consumption is restrained.

Title: Pulse width modulation circuit
Inventor: YAMASHITA HIDEHIRO
IPC: H03K7/08
Filed: 1986-08-02
Abstract: PURPOSE:To avoid occurrence of an action delay and an error output by selecting the specific one of those pulses produced by combinations of plural bits of the input data and securing an OR of the selected pulse. CONSTITUTION:This modulation circuit consists of a PWM (pulse width modulation) basic pulse generating circuit 6 which produces circularly and repetitively the pulses of different pulse widths, a combination selecting circuit 7 which selects the specific one of those pulses produced by the circuit 6 according to the ON/OFF combinations of plural bits forming the input data to perform the PWM, and an output means which secures an OR of the specific pulse selected by the means 7 and outputs it as a PWM output. Thus an error output is never produced despite a coincidence unable state since no coincidence detecting circuit is used. In addition, no action delay occurs owing to absence of a latch circuit. Then a PWM output is quickly obtained.
