Title: Dc regeneration circuit
Inventor: IIAN GOTSUDOFURI FUOBESUTAA
IPC: H03K5/003
Filed: 1994-10-25
Abstract: PURPOSE: To prevent the occurrence of an average level shift of digital data signals by providing a clamping transistor circuit on the output sides of first and second capacitors connected to first and second input lines respectively. CONSTITUTION: A demodulated signal may be present at the output of a demodulator as a low-level difference signal superimposed upon a fluctuating DC level. First and second capacitors C and D are connected to first and second input lines respectively. First and second clamping transistor circuits A and B connected to the output sides of the capacitors C and D respectively clamp voltage excursions on the output sides of the capacitors C and D when the differential voltage between the first and second input lines exceeds a predetermined value. Therefore, the average level shift of digital data signals superimposed upon a variable DC level which is present as the difference between the first and second input lines appears in the common mode to a comparator and does not affect the operations of a DC reproducing circuit.

Title: Electric refrigerator
Inventor: IINO YASUYUKI
IPC: F25D27/00
Filed: 1991-10-30
Abstract: PURPOSE:To prevent food from putrefaction by inhibiting the temperature rise in an electric refrigerator when its door is kept open for a long time. CONSTITUTION:A commercial power supply system 1 supplies electric power to an electric refrigerator. A change over switch 2 operates as the door is opened and closed, and a chamber light 3 in the refrigerator is on while the door is open. A switch 4 is controlled by a control section, for example. A fan motor supplies cooled air into the refrigerator while the door is closed. A positive temperature coefficient resistor device 6, such as thermistor and a winding 7a of a relay 7 are coupled in parallel between the change over switch 2 and the chamber light 3. A contact C is connected to a terminal 'c' side of the change cover switch, and a contact 7b is connected to a terminal 'b' side. When the chamber light 3 is on for a long time, the resistor device 6 increases its internal resistance so that electric current flows though a winding 7a, thereby operating the relay 7. Therefore, if the door is open for a long time, the fan motor 5 operates and supplies cooled air into the refrigerator.

Title: Printer
Inventor: SUZUKI NORIYUKI
IPC: B41J5/44
Filed: 1994-10-24
Abstract: PURPOSE: To connect plural printers even when a host device side has only one printer I/F part by switching the connection of the INF part according to the instruction of a connection control part. CONSTITUTION: When a 1st parallel I/F part 1 accepts the output from the external host machine 10, a command extraction part 2 extracts a command regarding connection switching from the output information and a switching control part 3 interprets the command and outputs a switching instruction for the connection to a connection switching part 4. Further, the command extraction part 2 outputs information other than the command to the connection switching part 4. Therefore, the information other than the command in the output information from the host machine 10 is outputted to an object selected by the connection switching part 4. On the other hand, other printers 11 and 12 are connected to 2nd and 3rd parallel I/F parts 5 and 6 outside. When the output object is this printer, the information is outputted to its internal print recording part 7 and printed.

Inventor: SHIRABE NAOTAKA
IPC: F02M61/18
Filed: 1994-11-21
Abstract: PURPOSE: To provide a fuel injection nozzle having a few time dependent change in a spray property. CONSTITUTION: A needle body 10 is formed with a jet 12 extending from the lower end of a valve seat 11 and a socket 40 having a through hole 42 coaxial with the jet 12 is mounted to the tip of the needle body 10. The diameter of the upstream side jet end 42a of a tapered surface 42b of the inner peripheral wall of a socket 40 formed with the through hole 42 is somewhat larger than the diameter of the jet 12. A gap 44 and a space part 45 following a gap 44 are formed between the through hole 42 and jet 12 by a recess 43 formed following the periphery of the upstream side jet end 42a. Immediately after the completion of jet, fuel is scraped up by the upstream side jet end 42a to deposit on the tapered surface 42b and intrude into the space part 45 from the gap 44 by wet-diffusion.  Thus, fuel is prevented from deposition on the periphery of the jet 12 and the inner wall of the jet 12, the deposit accumulation caused by the carbonization of the deposit fuel is hardly produced and the amount regulating performance and spray performance of a fuel jet nozzle are stabilized.
