Title: Paper feeder
Inventor: MURAKAMI TAKAYOSHI
IPC: B41J13/00
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To prevent any possible misfeed of paper surely from occurring even in such surroundings where temperature and humidity are largely varied by keeping a heeting means in the specified temperature according to the temperature of a separate roller detected by a temperature detecting means. SOLUTION: The temperature detection a separate roller 9 is carried out by a temperature detection element 5. In this connection, since a temperature is of characteristic determining a coefficient of static friction, as a characteristic of the temperature detecting element 5, it is necessary to make the extent of linearity so better, insofar as possible. Consequently, a thermister is used in this temperature detecting element 5 for the end. The detected temperature is compared with the set one, and if it is less than the set temperature, it moves to heating operation to raise the temperature as specified. In this heating operation, current energization and heating to a ribbon heater set up in an inner part of the separate roller 9, by way of example.

Title: Connecting header and refrigerator having the header
Inventor: SASAKI HIDETAKA
IPC: F25B49/02
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To effectively mount a fusible plug as a high pressure gas safety device and to simply decide a mounting position by providing the plug at a high pressure liquid side pipeline of a connecting header. SOLUTION: When three condenser units 1 are combined with a cooling unit through a connecting header 2A, 2b to constitute a refrigerating cycle, a refrigerant from the unit 1 is sent from each high pressure liquid side piping outlet to the cooling unit through a direct tube part of the header 2A. When the plurality of small-sized condenser units 1 are connected to provide a large refrigerating capability facility, the mounting of a necessary safety unit can be effectively executed since a fusible plug is previously provided at an outside position of the unit 1 at a connecting header body of the header 2A when the headers 2A, 2a are used.  Thus, since the plug mounting position is disposed at one place of a high pressure liquid side pipeline of the header, a real state of arrangement, an operating state or a fault can be easily confirmed, and the maintenance or replacement of the plug can be facilitated.

Title: Method and device for adjusting line level
Inventor: AKAGAWA KAORU
IPC: H04M9/00
Filed: 1987-03-11
Abstract: PURPOSE:To eliminate a need for manual adjustment of level at the time of replacement and to connect more data terminals with one pair of conductors by automatically adjusting the level of a telephone for instruction or a line for polling type data terminal. CONSTITUTION:A line 1 consisting of a pair of cable conductors and an impedance transformer 3 are connected at a T-type branching point 2, and a signal current is branched in proportion to the ratio between the characteristic impedance Z0 of the line due to the conductors and the input impedance Zi of the impedance transformer 3. The nearer a slave telephone set or a data terminal 5 are to a master equipment 10, the higher their input impedance Zi are. Therefore, the Zi at the terminal is automatically controlled by a level measurer/ comparator 4 and the impedance transformer 3 and is made lower. As a result, when replacing the telephone set in case of a trouble, the complicated adjustment work is made unnecessary, also, more data terminals can be connected to a pair of cable conductors of the polling type data line.
