Title: Drain neutralizing unit of engine driven air conditioner
Inventor: NISHIMURA OSAMU
IPC: C02F1/66
Filed: 1999-01-20
Abstract: PROBLEM TO BE SOLVED: To prevent exhaust gas from being discharged from a drain neutralizing unit, in a drain neutralizing unit of an engine driven air conditioner. SOLUTION: A drain neutralizing unit 40 is provided with a drain inlet 41c communicated with an exhaust system 30, a drain outlet 41d communicated with the atmosphere, and a vertically meandering drain passage formed between the drain inlet 41c and the drain outlet 41d.

Title: Burner port cleaning device
Inventor: SETOGUCHI HIROYUKI
IPC: F23D14/50
Filed: 1986-01-22
Abstract: PURPOSE:To enable continuous cleaning of a burner port, by a method wherein plural projections are formed around the burner port at the same pitch distance as that of the burner port, and a rotor holding tool is slid along a gas burner. CONSTITUTION:With a rotor holding tool 15 moved over burner ports 12, a rotor 13 is rolled. Action of pressing a projection part 14 against the burner port 12 is created by dint of a resilient body 17. Since the plural projection parts 14 are formed at each of a burner port, rolling of the rotor 13 causes continuous engagement and disengagement of the projection part 14 with and from the burner port 12. Thus, only through slide of a rotor holding tool 15 along the gas burner 11, a choked part in the burner port 12 is removed for free-flow. A recessed part 18 is a waiting position being not influenced by the combustion flame of a device.

IPC: H04Q9/00
Filed: 1992-01-28
Abstract: PURPOSE:To obtain the multiplex transmission system in which a master set side detects an address in duplicate when a duplicate address is in existence to a terminal equipment. CONSTITUTION:A master set 1 consists of a signal processing section 10, a transmission signal transmission section 11, a return signal detection section 12, and a duplicate signal detection section 13. The return signal detection section 12 receives and detects a return signal in the current mode from a terminal equipment and converts the signal into a logic level and sends the result to the signal processing section 10. The duplicate signal detection section 13 compares a signal level of each bit of the return signal with a predetermined level and outputs a duplicate signal to the signal processing section 10 when the signal level exceeds the predetermined level for each bit. When the number of the duplicate signals from the duplicate signal detection section 13, that is, the number of bits whose signal level exceeds the prescribed level in existence over a prescribed number, the signal processing section 10 judges it as duplicate address and outputs an alarm signal or the like including the address.

Title: Object inspector by transmitting radiation
Inventor: GEOFUREI HAADEINGU
IPC: A61B6/02
Filed: 1989-01-24
Abstract: PURPOSE: To suppress adverse effect of multiple scattering through a simple means by arranging a significantly large number of laminate members having high radiation absorbing coefficient between a primary radiation beam and a detector. CONSTITUTION: A significantly large number of laminate members 20 are arranged in front of a detector D in a slit unit 6. These members 20 have flat surfaces being developed like the beams of a fan around a primary radiation beam 3 such that the extensions intersect the beam 3. The member 20 extends vertically to the long side of individual detector and thereby vertically to the long side of a slit opening. With such an arrangement of members 20, a radiation incoming from a region on the outside of a region formed by the beam 3 scarcely arrives at the detector D but a scattering radiation from the region of beam 3 arrives at the detector D although it is attenuated. The attenuation depends on the ratio between the thickness and width of the member 20.
