Abstract: PROBLEM TO BE SOLVED: To facilitate the installation on site and coping with the line change after installation by mounting an air cleaner unit on a ceiling frame having an opening framed like a grid so as to close this opening. SOLUTION: The connections 4a of legs 4 to a ceiling frame 1 have U-shaped end pieces 4b for mounting the ceiling frame 1 such that the legs 4 are fitted in the end pieces 4b at the four corner bottoms and tightened by bolts 9 to fix this frame 1 having a rectangular or square shape in plan view.

Title: Remote controller
Inventor: HAJIKI KENJI
IPC: H04Q9/00
Filed: 1989-11-17
Abstract: PURPOSE:To decrease current consumption in a detecting part by constituting a power on signal S0 with the several pulses containing a start pulse P1, putting usually only the detecting means on the active condition and turning on the whole detecting part when P1 was confirmed. CONSTITUTION:In a remote control equipment, a power on signal S0 sent out of a transmission part 2 is constituted with the several pulses beginning from start pulse P1. Also on a detecting part 6, the start pulse P1 detecting means and the means deciding the inputted pulse string is the power on signal S0 or not are set. When the pulse signal is inputted in the start pulse signal detecting means, it is decided that the inputted pulse is P1 or not by, for instance, detecting the pulse width, and when it is not P1 it is waited for the next pulse inputting without treatment about that pulses. When it is decided as the P1, the power on signal judging means is turned on and it is decided the power on signal S0 or not by, for instance, counting the number of pulses following the P1. Only after judging the power on signal a main circuit 30 is energized.

Abstract: PURPOSE:To reduce mounting space and to improve mounting efficiency by providing a D/A converting means to convert the binary signal of plural switch sensors into an analog signal corresponding to the respective switch sensors and an A/D converting means to convert the analog signal into a digital signal. CONSTITUTION:Plural pieces of information to indicate the state of sensors A to F are converted into a voltage level in a lump by a D/A converting part 1 put near a sensor part and made as an analog signal. It is conducted to an MPU 3 by one signal line and after that, it is returned to the digital information to indicate the state of the original sensors A to F by an A/D converting part 2 provided adjacent to the MPU 3 part. In this case, processing is attained as if the sensor A to F information is transmitted parallel at the side of the MPU 3. Thus, the number of the signal lines to be delivered within a device can be reduced broadly and besides, the number of the signal lines to an MPU 3 periphery can be reduced.

Title: Detecting circuit for overvoltage of dc power supply device for parallel operation
Inventor: TSUCHIDA HIROSHI
IPC: G05F1/10
Filed: 1989-11-21
Abstract: PURPOSE:To always monitor an over voltage correctly without being affected by the fluctuation of voltage drop in the normal direction of a diode for reverse current prevention by directly monitoring a voltage applied to a load to detect a over voltage state. CONSTITUTION:When voltage V2 impressed to a load 4 is turned to an overvoltage state, a detecting signal is outputted from a comparator 7. When the overvoltage state is caused by the other DC power supply connected to feeding lines 5, a reverse current preventing diode 3 in the power supply device concerned is turned to a reverse bias state, the output of a comparator 8 is turned to an 'L' level and no alarm signal is outputted from an AND gate 9. When the overvoltage state of voltage V2 is caused by the power supply device concerned, the diode 3 is held at the forward bias state, outputs from both the comparators 7, 8 are turned to 'H' levels and an alarm signal is outputted from the AND gate 9. Consequently, whether the power supply device itself outputs abnormal voltage or not can be correctly detected without being influenced by variation in the forward dropped voltage of the diode 3.
