Filed: 1989-12-21
Abstract: PURPOSE:To correct a fault point locating result and improve a locating accuracy by obtaining the sag ratio per unit length of a registered line distance by using an FL apparatus. CONSTITUTION:A high frequency impulse emitted from an FL apparatus 51 is fed to the starting point 54 of a transmission line via a coaxial feeder 52 and a coupling circuit 53, reflected at a junction 56 and returns to the FL apparatus 51 via the starting point 54. Part of a reflected wave is further reflected at the starting point 54, transmit ted through the transmission line, reflected again at the junction 56 and returns to the FL apparatus. A time T1 from the emission of the impulse to a return to the FL apparatus after a reflection at the junction 56 and a time T2 from the emission of the impulse to the return to the FL apparatus after two time reflections at the starting point 54 and the junction 56 are measured. At this time, the product of a time (T2-T1)/2 and a pulse transmission speed Vp equals to the sum of a registered line distance l and the sum total of sags DELTAl for the registered line distance l. There fore, when a sag ratio DELTAl/l per unit length of the registered line distance is obtained in advance, a high accuracy of located distance can be obtained by conducting a correction on a fault point measured by the FL apparatus in a transmission line fault.

Filed: 1989-12-20
Abstract: PURPOSE:To smooth operation from starting to a steady power control state by providing a current comparator which emits its output in a state when an inverter output current has exceeded the set upper limit value. CONSTITUTION:A voltage/frequency converter 16 stops frequency conversion operation in the reducing direction of inverter output frequency on receiving output signals from an output current detection comparator 17 and a phase detection comparator 18. The comparator 17 receives the detection signal IO of a high frequency transducer CT3 to convert it at a proper signal level and to emit an output signal at a point of time when it exceeds the upper limit current set value ISU, while the comparator 18 receives a detection signal VO and a signal IO for computing a phase angle between both signals in order to emit an output signal at a point of time when it becomes lower than the lower limit phase angle set value. The output signal of the converter 16 is inputted into an operation pulse divider 19 for performing PWM operation of inverter operation in order to give a dividing command to the base driving unit BDU of an inverter part 3. A protection circuit 20 commands an inverter stop due to an operation stop of a starting time frequency operation circuit 14 and the divider 19 when the input exceeds the set value. In this way, operation can be smoothed.

Abstract: PROBLEM TO BE SOLVED: To provide a dental tip not causing any damage to teeth and artificial parts in a mouth during medical treatments and having a most appropriate natural frequency that resonates to an excited frequency emitted from an ultrasonic generator that a dentist operates. SOLUTION: Plastics and filler materials are mixed for forming a dental composite. In preparing a monolithic dental chip for an ultrasonic scaler that is provided with a base part to be connected to an electric source and a top part to work at a tooth or at a body part to be treated medically, two kinds of composites of different compositions are selected, and these two composites are mixed according to a specified weight ratio before use. The above-mentioned method is the manufacturing method to obtain a dental tip aimed to possess a specific natural frequency. Therefore, a composite is formed experimentally with changing mixing ratios of two kinds of composites, and the natural frequency of the formed composite is measured in terms of the composition.  Thus, the relationship between the natural frequency and the composition of a formed composite is experimentally understood, and a required mixing ratio of two kinds of composites in forming a dental tip is determined based on the obtained relationship.

Title: Method of controlling spurious resonart cauity condition in electronic apparatus
Inventor: JIYOOJI EI PAASON
IPC: H01P1/212
Filed: 1989-12-20
Abstract: PURPOSE: To prevent the reliability of an electronic system from being deteriorated due to an unexpected resonance condition in a cavity by deciding a proper maximum signal frequency and securing a size of the cavity so as to increase the resonance frequency higher than the critical frequency of each case. CONSTITUTION: A size of each cavity in a case 1 is adjusted to increase a cavity resonance frequency more than a critical frequency. For example, a horizontal buffle 14 is placed in the middle of a border between a top part 12 and a bottom part 13 of a cavity between a circuit panel 7 and a cover 5 to provide two smaller blocks having a resonance frequency higher than the critical frequency. If the critical frequency is higher than the desired frequency, a vertical buffle 15 is used to divide again this space into a plurality of smaller cavities. Thus, it is prevented that a spurious signal is caused at random in a circuit due to occurrence of unexpected cavity resonance in the case 1 containing an electronic device.
