IPC: F04D27/00
Filed: 1986-08-26
Abstract: PURPOSE:To increase partial load efficiency, by determining an r.p.m. of a high speed motor as desired by sensing a suction pressure, suction temperature, a final charging pressure and a flow rate of a compressor. CONSTITUTION:A centrifugal compressor 1 is driven by a high speed motor M12. A gas suction pressure P1, a suction temperature T1, a charging pressure P2, P3, and a flow rate F3 are sensed to be applied to a calculation and regulation unit 5 and then to be output as an r.p.m. command. The output is commanded to inverters 6, 7 for making a setting of respective motors. With the arrangement, an r.p.m. of a low pressure compressor and a high pressure compressor is set as desired in a partial load, whereby partial load efficiency can be improved.

Title: Automatic switching device for telephone set
Inventor: IWATA YASUSHI
IPC: H04M1/72
Filed: 1986-08-26
Abstract: PURPOSE:To obtain an automatic switching device provided with an automatic transfer function and a privacy call function used in common by adopting a constitution in which a switching element is turned on when the output voltage of a bridge type rectifier circuit exceeds a setting value. CONSTITUTION:Telephone sets T1, T2 are expressed equivalently in series circuits each comprising a bell and a capacitor and give a low resistance when a handset is hooked off. With a call signal given, a current is conducted through a capacitor, a voltage exceeding the setting value of a threshold value setting means 4 is outputted from a rectifier circuit 1 and the switching element 3 of the telephone set hooking off the handset at first keeps its ON-state by a current conducted the low resistance. Since the line voltage of subscriber lines L1, L2 is lower than the threshold value because of the low resistance, the switching element of the other telephone set turned once off is not turned on to attain privacy call. When both the handsets of the telephone sets of the switching sender and destination are hooked off and the handset of the telephone set of the switching sender is hooked on, the switching element of the switching sender is turned off and that of the switching destination is turned on to apply the switching.

Title: Disk and disk defect detection apparatus
Inventor: SANADA SATORU
IPC: G11B20/10
Filed: 1994-08-24
Abstract: PURPOSE: To obtain a disk defect detection apparatus by which a delay in the access time is reduced. CONSTITUTION: All the sectors on an optical disk 1 is inspected for defects. When a defective sector is detected as a result, the sector address of the defective sector is stored in a region A in a storage element 3. When the inspection of all the sectors has been finished, the region A in which the address of the defective sector has been stored is searched, and the existence of a burst defect is investigated. The existence of the burst defect is judged according to whether a region whose sector number is identical and in which track numbers are continued in five or more tracks exists or not. When a burst defect exists, sectors which exist before and after the track in which the burst defect exists and which have the same sector number are regarded as defective sectors so as to be registered in a region B in the storage element 3.

Title: Refrigerant recovery device for heat exchanger
Inventor: AIZAWA HITOYOSHI
IPC: B01D53/26
Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To improve a refrigerant recovery rate from a refrigerant pipeline by providing in a refrigerant recovery circuit a refrigerant feeder for sucking a refrigerant from a heat exchanger side and feeding it under pressure to a refrigerant storing bomb side. SOLUTION: When negative pressure is achieved in a bomb 16 and a refrigerant feeder 13 is driven, refrigerant in a refrigerant pipeline 2 is sucked from an indoor machine 1 side and fed under pressure to the bomb 16 side in accordance with the suction and pressure feed operation of the refrigerant feeder 13. In the bomb 16, successively supplied refrigerant gas is stored and the pressure of the bomb 16 is gradually increased because of the refrigerant gas. Even when this pressure becomes equal to that of the refrigerant in the refrigerant pipeline 2 of the indoor machine 1, the refrigerant gas is continuously fed to the bomb 16 because the refrigerant gas passing through the refrigerant feeder 13 is pressurized to a high pressure so that the refrigerant gas is fed to the bomb 16 until the pressure of the inner part of the refrigerant pipeline 2 reaches negative pressure.  Thus, the refrigerant recovery rate from the refrigerant pipeline 2 is raised.

Title: Exhaust energy recovery device
Inventor: AKIYAMA KAZUNARI
IPC: F02B37/14
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To charge a battery with electricity by utilizing energy recoverable at brake time to the maximum extent in an exhaust energy recovering device to recover energy by generating electric power by a turbocharger rotating electric machine when exhaust energy is large by arranging the turbocharger rotating electric machine arranged in a turbocharger besides a vehicle generator. SOLUTION: Signals from a brake switch 19 in the most recent past prescribed time are counted by a counter 16-1, and a brake frequency is found. A regulator is controlled so that a charging quantity at ordinary travel time when a brake is not applied is reduced as the brake frequency becomes large. That is, room for being charged is made large. At brake time, a battery is charged with electricity by utilizing recoverable energy to the maximum extent. Since power generation by a vehicle generator 1 at ordinary travel time consumes fuel, charging is reduced thereby, so that fuel consumption is improved. Energy recovering efficiency at brake time is also improved.

Abstract: PURPOSE:To improve the reduction of character recognition rate due to small dirt with high density adhered to an original or noises by erasing black information from an unrecognized character up to the maximum number of continuous black information obtained from an unnecessary writing extracting area. CONSTITUTION:When the unnecessary writing extracting area 4 of a business from 1 is scanned by a scanner 6 and black information due to dirt or noises is extracted, an unnecessary writing extracting part 13 counts up the number of black information continued in the horizontal direction X or vertical direction Y of the business form 1 and stores the maximum number of continuous black information in a memory 14. If a character recognizing part 10 can not recognize a character due to dirt or a noise as the result of scanning a recognition character entering area 3, the part 10 outputs a recognition disabled signal to the unnecessary writing extracting part 13. One black information is erased from each of an unnecessary black information block obtained from a character entering frame and a black information block obtained from the character to recognize the character. If the character can not be recognized yet, one more black information is recognized and the erasing and recognition are repeated up to the value of a maximum memory 14.
