Title: Data transmitter for elevator
Inventor: NAKAJIMA YUTAKA
IPC: B66B3/00
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To avoid any influence of noise caused by surge, etc., on the series data transmission between main controller side and a cage and a landing of an elevator. SOLUTION: A voltages of a signal transmission passage 6 and an electric power transmission cable 7 are detected by a detector 36 and a voltage detector 81 and when those detection voltage values exceed the preset reference values, output signals are led out from comparing circuits 37, 82. The output signal of the comparing circuit 37 makes ON/OFF control to a switching circuit 51g connected to the transmission passage 6, therefore, even if a thunder surge of a high level is induced in the transmission passage 6, application to IC, etc., constituting a terminal control apparatus 51, etc., is shut off, any erroneous action and/or damaging accident can be avoided. In addition, since even any abnormal voltage signal on the transmission cable 7 can also protect each of control apparatus 33, 11, 15 by means of the output of a voltage comparing circuit 82, similar effect can be obtained.

Title: Freezing cycle
Inventor: UMETSU KENJI
IPC: F25B5/02
Filed: 1990-04-27
Abstract: PURPOSE:To improve energy efficiency and reduce the vibration of a compressor by installing a first intake means which introduces refrigerant from a refrigerating chamber cooler to one party of compression section of the compressor section, a second intake means which introduces refrigerant from a second cooler to the other party of compression section of the compressor, and a communication means which communicates the first intake means with the second intake means. CONSTITUTION:Two cylinders 3 and 4 are housed in a compressor 1. Refrigerant from a refrigerating chamber cooler 12 is compressed by a refrigerating chamber cylinder 4 while refrigerant from a freezing chamber 17 is compressed by a freezing chamber cylinder 3 respec tively, which makes it possible to compress refrigerant from the refrigerating chamber cooler 12 kept at a relatively higher temperature and higher pressure without low pressure compres sion, keeping the high pressure, thereby reducing compression work. The two cylinders 3 and 4 in the compressor 1 are laid out in the lower part of a drive shaft where its rotation angle is deviated by about 180 deg. vertically. Therefore, compression takes place twice during one rotation and compression load is virtually averaged, thereby reducing the vibration of the compressor 1. Furthermore, since a first refrigerant intake pipe 13 is communicated with a second refrigerant intake pipe 18 with a communication pipe 24, it is possible to meet an increase and decrease of load of the refrigerating chamber cooler 12 by opening and closing a solenoid valve 25.

IPC: B65H7/02
Filed: 1996-05-09
Abstract: PROBLEM TO BE SOLVED: To provide an automatic document feeder and a document size detector capable of preventing the erroneous detection of the size of a document. SOLUTION: The width of the document is detected and then, the output of first, second and third document length detecting sensors 125, 126 and 127 which are arranged at fixed intervals from a paper feeding part is checked. When the sensor output is tuned off (the absence of the document), the size of the document is fixed. The length of the document is decided by the document length detecting sensor of the turning on of the final sensor output (the presence of the document) obtained in such a manner and the size of the document is fixed by the document length and the detected document width. When the document is temporarily absent like this way, the sensor output after that is ignored and even if a thing except the document to be fed is placed on a document platen, the erroneous detection never occurs.

Title: Synchronizing signal separating circuit
Inventor: YOKOTA MASAFUMI
IPC: G11B20/06
Filed: 1979-09-07
Abstract: PURPOSE:To separate a synchronizing signal securely by performing synchronizing component separation by providing a tuning circuit that tunes to only a frequency component equivalent to the synchronizing signal in a reproduced signal. CONSTITUTION:The access of an optical head is attained in the radius direction of an optical disk to reproduce recording contents on a spiral recording track, and consequently a reproduced signal is obtained from photoelectric converter 1 is obtained and then supplied to FM demodulator 4 via preamplifier 2 and limiter 3. Since a tuning frequency is turned to only the frequency component of a synchronizing signal in the reproduced signal from amplifier 2, the synchronizing signal is outputted only in the synchronizing signal period. The envelope of this output signal waveform is detected by envelope detector 6, the output of which is sent to comparator 8. Comparator 8 compares reference level L to the output of detector 6 to output the synchronizing signal with the comparison result separated. Thus, the high-Q tuning circuit is used to obtain the separate synchronizing signal, so that the separation will be secured without any influence of noises, etc.
