Title: Heat exchanger with fin
Inventor: TANIGUCHI MITSUNORI
IPC: F25B39/02
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To promote the improvement in the amount of heat exchange, to suppress the sudden lowering of the amount of heat exchange at the time of frosting, and to promote the reduction of the frequency and the time of defrosting operation, concerning a heat exchanger with a fin that transmits and receives heat between the refrigerant of air conditioners, refrigerating machines, car equipment, etc., and fluid such as air. SOLUTION: The louvered section 7' on a fin surface is formed to be parallel to the direction of a draft, and the louvering 7 is formed into a semi-circular shape, so as to promote the turbulent effects of air, while suppressing the increase in ventilating resistance. Moreover, the air side heat transfer rate between air and the fin can be improved, and the amount of heat exchange can be also improved. Furthermore, even when the moisture in the air is condensed on the fin surface, the condensed moisture at the louvered portion is easy to get discharged from the louvered portion by a draft. Further, the increase in the ventilating resistance of the heat exchanger and the decline in the amount of heat exchange at the time of heat operation can be suppressed.

Title: Method for stabilizing frequency of oscillator and oscillator using the same method
Inventor: TAKAKI KEIJI
IPC: H03B5/04
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To stabilize the frequency by controlling the oscillator, which feeds part of the output of an amplifier using an active element positively through a phase shifter with current fluctuations that are correlative with a phase. SOLUTION: In a phase shift type transistor oscillator, a phase shifter 3 controls the phase of the output of an amplifier 1 over a wide range with a control voltage Vcont and feeds it back positively to the amplifier 1. A low-frequency amplifier 6 amplifies a low-frequency signal passed through a low-pass filter 5, and an attenuator 7 adjusts the level to generate current fluctuations of low frequency. Here, the relative spectrum intensity of frequency fluctuations and current fluctuations increases in low-frequency phase shift correlation coefficient. Therefore, the phase and amplitude are adjusted so as to cancel the frequency fluctuations according to the polarity, and a voltage corresponding to the current of mean current fluctuations of low frequency is applied to Vcont, to reduce the phase fluctuations following up the mean current fluctuations.  Consequently, the frequency is stabilized, and the noise of a signal amplified by the oscillator is reduced.
