Title: Air separator
Inventor: TANAKA MASAYUKI
IPC: F25J3/04
Filed: 1993-06-28
Abstract: PURPOSE:To efficiently recover product nitrogen having a relatively high pressure by introducing gas from a lower position from an introducing position of high purity nitrogen gas in a low-pressure tower to be guided to an expansion unit. CONSTITUTION:Product nitrogen (high purity nitrogen gas) is introduced from a top of an upper tower (low-pressure tower) 24 via a nitrogen introducing passage 42. The nitrogen is guided out of a cold insulation box 16 through a subcooler 28 and a main heat exchanger 18, and compressed by a product nitrogen compressor 43. Waste nitrogen gas is guided from a lower position than an introducing position by the passage 42 in the tower 24 via a waste nitrogen introducing passage 44. This gas is supplied to an expansion turbine 30 through the subcooler 28 and the exchanger 18 to rotate the turbine 30 and to contribute to generation of cold, and to be then exhausted through a gas exhaust passage 46 out of a system. Thus, the product nitrogen having relatively high pressure can be efficiently recovered.

Abstract: PURPOSE:To suppress distortion of sinusoidal output waveform through a simple circuitry by providing a waveform shaping circuit section for delivering an output from an error amplifier section to a PWM circuit section and distributing output from the PWM circuit section to two system inverters, and a zero- crossing signal generating circuit. CONSTITUTION:An error amplifier section 37 compares sine wave output voltages from inverters 29, 30 with a reference signal voltage fed from a sine wave reference voltage section 26 and produces an error signal. The error signal is compared at a PWM circuit section 35 with a triangular wave and converted into a pulse width signal corresponding with the voltage level of the error signal. A waveform shaping circuit section 31 extracts control information from the pulse width signal and distributes the information to the inverters 29, 30. In other words, the pulse width signal is employed while being inverted for the control of the inverter 29 whereas the pulse width signal is employed as it is for the control of the inverter 30. Furthermore, a zero-crossing signal generating circuit 25 generates a zero-crossing signal to improve the waveform of sinusoidal output voltage in the vicinity of zero potential.

Title: Wire disconnection detecting method
Inventor: KOGA HIROMI
IPC: G01N21/956
Filed: 1994-07-08
Abstract: PURPOSE:To automatically detect the disconnection of a bonded wire by tracking black or white picture elements indicating the existence of a chip or the wire, moving an observation point, and detecting the change of the moving direction of the observation point. CONSTITUTION:The chip angle 10 of a semiconductor chip 4 is detected, and the number of counts is set in response to the length of a wire 5 or 6. Whether the chip angle 10 is at the right end or left end is registered, whether eight picture elements around an observation point are white or black is confirmed, a picture element for starting observation among eight picture elements around the observation point is selected as a start point, e.g. chip angle 10, and black picture elements are detected. Eight picture elements around the observation point are observed CCW when the first observation point is located on the right side of the chip 10, and CW when it is located on the left side to save wasteful observation. Individual picture elements are observed in sequence. When a black picture element is detected, it is registered as a new observation point. If the observation point proceeds in the opposite direction to the chip angle 10 (start point), the wire is judged to have a disconnection.

Title: Silencing muffler for refrigerant cycle compressor
Inventor: YOKOMIZO YUKIO
IPC: F04B39/00
Filed: 1990-06-18
Abstract: PURPOSE:To dissolve the transmission of pulsation to refrigerant piping after a silencing muffler so as to prevent the generation of vibrational noise by leading refrigerant accompanied by pressure pulsation from a refrigerant inlet pipe, and discharging it from an outlet pipe after circulating it in one direction inside a circulating duct so as to reduce pressure pulsation. CONSTITUTION:Discharge refrigerant accompanied by pressure pulsation generated by the compression of a compressor 2 is led from an inlet pipe 6 into a circulating duct 5 formed of a pipe body 4 into annulus ring shape and circulated in one direction inside this circulating duct 5. After its flow speed change vector is transmitted to the circulating duct 5 and reduced by this circulation inside the circulating duct 5, the discharge refrigerant is discharged from an outlet pipe 7. The refrigerant discharged from the outlet pipe 7 thereby has constant pressure and is sent to a four-way valve, an outdoor heat exchanger, and the like. That is, the refrigerant flow speed change vector generated at the compressor 2 is reduced by a silencing muffler 1 so as not to be transmitted from the silencing muffler 1 on, and thus the four-way valve, the outdoor heat exchanger, and the like are prevented from being vibrated.

CONSTITUTION:The sheet 6 which is <=0.3mm in thickness can be suitably rolled with a comparatively compact rolling equipment by rolling with the work rolls 2 having a diameter of 60-120mmPHI. And the durability to roll wear can be suitably given by taking the diameter of roll as >=60mmPHI, on the other hand, the rolling under comparatively lower load is enabled and also the control of the surface roughness of sheet is made easy by taking the diameter of roll as <=120mmPHI. The generation of cross buckle is prevented and then the generation of sheet breaking or the like is avoided by setting the tension on the outlet side of rolling stand at >=25kg/mm<2> and <=70% of the tensile strength. In this way, excessive correcting process isn't needed and the sheet of good quality can be obtained with a high yield.
