Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To provide the stabilized operation while withstanding high voltage and large surge near an ion generating power source by providing a high frequency inverter in a primary side of an insulating transformer for raising the alternating current voltage to be rectified so as to obtain the high-tension direct current voltage and for insulating from the grounding electrical potential. SOLUTION: This ion generating power source 12 is formed of an insulating transformer 112, a step-down transformer 114, and a rectifier 116. A high frequency inverter 14 for voltage control and high-speed switching is arranged in a primary side of the insulating transformer 112 as a low electrical potential side. Desirable direct current voltage is generated in the output of the rectifier 116 by the voltage control such as a change of control angle of the high frequency inverter 14, and supplied to an ion generating section 102. A high electrical potential side of the ion generating power source 12 is formed of only the step-down transformer 114 and the rectifier 116, and since a semiconductor switch is not included, wrong operation and breakdown of the semiconductor switch due to a large surge to be generated when a discharge breakdown is generated in an ion source 100 can be restrained. The high electrical potential side of the ion generating power source 12 can be quickly cut by switching the high frequency inverter 14.

Title: Gradient magnetic field generator for magnetic resonator
Inventor: USUI YOSHIYUKI
IPC: G01R33/20
Filed: 1990-11-13
Abstract: PURPOSE:To prevent possible damage to a gradient magnetic field coil by always monitoring the temperature of a gradient magnetic field coil to check or stop an output of a power source for gradient magnetic fields immediately before the temperature thereof reaches an abnormally overheating value. CONSTITUTION:A temperature sensor 23a detects the temperature of a gradient magnetic field coil 20a and sends the results of detection to a protection circuit 24a built in a system controller 22a. The system controller outputs no warning protection signal to a power source 21a when a measured temperature value sent is below a set operation level value. To the contrary, when the output value of the temperature sensor 23a exceeds the set operation level value of the protection circuit 24a, that is, when a temperature value of the gradient magnetic field coil 20a rises abnormally, a warning protection signal is outputted to the power source 21a from the protection circuit 24a. Thus, the power source 21a regulates or stops own current output before the temperature of the gradient magnetic field coil 20a reaches a burning temperature.

Title: Demodulation circuit
Inventor: TAKEUCHI AKIHIRO
IPC: H04N5/93
Filed: 1986-12-19
Abstract: PURPOSE:To obtain the effect of noise suppression at a minimum muting time by placing a muting circuit before a low pass filter so as to attain muting. CONSTITUTION:A signal having omission is inputted to a demodulator 8 and a noise detection circuit 7 from an input terminal 11 and a muting pulse is outputted at an output of the noise detection circuit 7. Moreover, the output of the demodulator 8 is discontinuous due to the defect of signal and spike noise is generated, but the time is coincident with the period of omission and no further spread exists. The period is muted by a muting circuit 10 controlled by a pulse detected by the noise detection circuit 7 and the result is inputted to a low pass filter 9 as a signal without large spike noise. Thus, no noise is demodulated in the output of the low pass filter 9 and the muted demodulation output appears. Thus, the noise suppression effect is obtained by a minimum muting time.

Title: Radio receiver
Inventor: SATO AKIHIRO
IPC: H04B1/16
Filed: 1986-12-19
Abstract: PURPOSE:To simultaneously attain the improvement of a distortion factor in the reception of a strong electric field and the reduction of power consumption in the reception of a weak electric field, by changing the idling current of a power amplifying stage corresponding to the electric field strength of a reception signal. CONSTITUTION:A control stage 10 controls the idling current on the power amplifying stage 7 corresponding to the output signal level of a level detecting stage 9. If the electric field strength of the reception signal is large, it is possible to permit a satisfactory idling current to flow on the power amplifying stage 7, and to prevent crossover distortion or switching distortion from being generated, and to perform satisfactory reception. Also, if the electric field strength of the reception signal is small, the idling current on the power amplifying stage 7 is decreased, and thereby, it is possible to reduce the power consumption.

Title: Connecting rod
Inventor: KANO TOMOHIRO
IPC: F16C7/02
Filed: 1993-12-03
Abstract: PURPOSE:To reinforce a small end part without causing weight increase and prevent the oscillation of a connecting rod caused by the behavior of a piston by providing the inner peripheral surface of a small end hole, into which a piston pin is inserted, with taper parts enlarged in diameter toward the thrust faces of both small end parts by plastic machining. CONSTITUTION:When explosion load W acts upon a piston pin 22, the piston pin 22 is elastically deformed in a flexural direction. Since the inner peripheral surface 24 of a small end hole 23 is of shape corresponding to the shape of the piston pin 22 at the time of flexural deformation by taper parts 25, there is no partial contact between the piston pin 22 and the inner peripheral surface of the small end hole 23 so as to secure large contact area between the outer peripheral surface 22a of the piston pin 22 and the inner peripheral surface 24 of the small end hole 23. The concentration of explosion load on a specific part in the inner peripheral surface 24 of the small end hole 23 is therefore relieved to suppress maximum tensile stress, acting upon the inner peripheral surface 24 of the small end hole 23 caused by the flexural deformation of the piston pin 22, to a small degree.
