Title: Cryogenic liquefying refrigerator
Inventor: SHIBANUMA KIYOSHI
IPC: F25B9/02
Filed: 1987-12-16
Abstract: PURPOSE: To facilitate operation by providing a bypass line for returning the gas from an object to be cooled back to the suction side of a reducing pump during operation thereof while bypassing a heat exchanger at the time of preheating. CONSTITUTION: Valves 47a, 47b are opened while a valve 71 is closed upon starting a reducing pump 20. Return gas from an object 50 flowing through an object 50 to be cooled is thereby fed through a reducing line 34 and a bypass line 70 to a first heat exchanger 41a where the temperature is recovered before the gas is returned back to the suction side of the pump 20 through the line 34. When the temperature of the object 50 is lowered down to a steady temperature, e.g. 4.5 K, precooling operation is finished and a transition is made to steady operation. Since the effect of temperature rise of heat exchangers 41a-41e due to the gas being returned from the object 50 back to the pump 20 during operation thereof can be suppressed at the time of preheating the object 50, trial and error operation of the pump 20 can be eliminated at the time of precooling.

Title: Ac to dc converter
Inventor: TANAKA CHIKARA
IPC: H02J5/00
Filed: 1988-12-16
Abstract: PURPOSE:To improve the reliability of an apparatus by arranging a DC switch between a voltage type self-excited converter and a smoothing capacitor or said smoothing capacitor between the voltage type self-excited converter and DC switch or by using the arrangements at the same time. CONSTITUTION:When a short-circuit or ground fault occurs on the DC side, a short-circuit detector 12 or an earth detector 10 detects the fault so that an OFF signal is given from a gate control circuit 13 to a DC switch and the DC switch 4 is brought to an OFF state to cut OFF an overcurrent flowing through an AC to DC converter 1. In this manner, the overcurrent ceases to flow through the AC to DC converter 1 over a long period of time and the breakdown of the AC to DC converter 1 by the over-current can be prevented beforehand. Also, it is possible to prevent the discharge of the smoothing capacitor 3 so that an apparatus can be restarted even at high speed without recharging the smoothing capacitor.

Title: Heater control device of air/fuel ratio sensor
Inventor: AOKI KEIICHIRO
IPC: G01N27/04
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To prevent an air/fuel ratio sensor from being cooled even during a long idling operation after a highly loaded running. SOLUTION: A detection element 111 of an air/fuel ratio sensor 11 is heated by an incorporated heater 112 and is maintained to be at approximately 650 deg.C. After highly loaded operation, idling or low-speed running state results. Then, when a radiator fan operates, a control part 13 detects the operation of the radiator fan and increases power supplied to the heater 112. As a result, the radiator fan cools the air/fuel ratio sensor 11, thus preventing the detection accuracy of the sensor 11 from deteriorating.

Title: Control of synchronizing position in looper
Inventor: CHINO TOSHIHIKO
IPC: B21C49/00
Filed: 1988-12-15
Abstract: PURPOSE:To prevent a strip from meandering without hindering the operation of a line by detecting a quantity of meander of the strip in a looper and controlling a synchronizing position in the looper in accordance with the quantity of meander detected. CONSTITUTION:In the control of the synchronizing position in the looper, e.g. when a detected quantity of meander exceeds a 1st quantity preset the synchronizing position in the looper carriage 3 is lowered inaccordance with the quantity of meander to shorten the length of a looper strand and to reduce the quantity of meander. As a result, when the quantity of meander is smaller than a 2nd quantity preset, the synchronizing position must by raised. When the transportation of the strip S on the inlet side is stopped on account of welding, etc., the control of the synchronizing position is stopped before the transportation is stopped to secure a quantity of storage of the looper strip. By this method the carrying speed of the strip S in the process part becomes stable.

Title: Optical scanner
Inventor: SEKIKAWA YOSHITO
IPC: G02B26/12
Filed: 1993-12-16
Abstract: PURPOSE:To prevent the rigidity of an optical housing near the fitting part of an (ftheta) lens from being impaired and to make dust hardly enter the inside of the optical housing. CONSTITUTION:A laser beam L deflected by a polygon mirror 22 is passed through lenses 26 and 28 constituting the (ftheta) lens and reflected on a first reflecting mirror 36 toward the mirror 22 side. Basides, it is reflected on a second reflecting mirror 38 (cylindrical mirror) arranged more backward than the mirror 22 and a photoreceptor drum 30 is exposed by it. Since an irradiation port 40A formed on the optical housing 40 is positioned near the second mirror 38, the aperture area need not be secured large. Since the dust hardly enters, an aperture need not be formed near the lenses 26 and 28 and the rigidity of the housing 40 is not impaired, such fear as an inaccuracy in the fitting of the lenses 26 and 28 is eliminated.

Title: Leak current measuring method for lightening protector
Inventor: SHINOHARA TAKAHIRO
IPC: H01T15/00
Filed: 1987-12-15
Abstract: PURPOSE:To determine the lightening protector leak current corresponding to the resistance with good accuracy by separating the total leak current into fundamental wave component and harmonic components, and subtracting sinusoidal waves equal to the current corresponding to electrostatic capacitance from the fundamental wave component in the total leak current. CONSTITUTION:The total leak current flowing in the grounding wire of a lightening protector 1 is separated into fundamental wave and harmonic waves. A sinusoidal wave is generated having the zero point in the position 90 deg. advanced or 270 deg. delayed from that of the zero point positions existing after an arbitrary zero point position with attention paid on among the separated fundamental waves and for the harmonic wave of the lowest order among the higher harmonics with its inclination direction of the waveform passing the zero point opposite to the inclination direction of the zero point of the fundamental wave which is the nearest to the zero point with attention paid on and therein the inclination direction of the waveform passing this zero point is the same as the fundamental wave at the zero point with attention paid on. Subtraction is made from the separated fundamental wave, and the zero point position of the fundamental waveform remaining after this subtraction moves to the position 90 deg. delayed from the zero point of the sinusoidal wave, and the wave height of the sinusoidal wave is adjusted until coincidence is obtained with the zero point position of the harmonic wave of the lowest order. This allows remaining of only the resistance-corresponding leak current in the total leak current.
