Title: Snowfall sensor
Inventor: TSURU KENTARO
IPC: G01W1/14
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To improve operability by providing a means to measure the number of light rays interrupted by snows and interruption time and a means to determine the condition of snow and snowfall and providing correct indexes in advance for preventing snow damage regardless of the condition or amount of snow. SOLUTION: N×M pieces of light sources 1 and the same number of light receivers 3 continuously project and receive light rays in normal times, and an information tabulating part 6 determines that there is no snowfall unless the tight rays are interrupted. When snow 7 starts to fall and a portion of a plurality of light rays are interrupted, an interruption signal of light rays reaches the information tabulating part 6 over a signal line 5. The information tabulating part 6 detects which light rays are interrupted from the number of a terminal through which the interruption signal is inputted. The area of snow is calculated from the number of light rays interrupted by one snowflake, and the fall time of snow is computed from the area and interruption time of snow. Whether snow is dry or damp is determined from the area and fall time of snow.  It is possible to determine the magnitude of snowfall by tabulating these data for a predetermined period of time.

Title: Inverter apparatus
Inventor: HAYAZAKI YOSHIKI
IPC: H02M1/08
Filed: 1992-09-14
Abstract: PURPOSE:To reduce current distortion by suppressing sudden voltage fluctuation caused by the reverse recovery of a current regeneration diode, and shaping the waveform of a load voltage similar to a control waveform. CONSTITUTION:An electrostatic induction thyristor 1 and a MOS transistor 4 on the high side are tunred off. Then, a MOS transistor 6 on the low side is turned on almost at the same time. When a current flows through a regenerating diode 7, the reverse recovering current of the regenerating diode 7 flows through the path of a DC power supply   the regenerating diode 7   a resistor 5   and the MOS transistor 6. Thus, the regenerator diode 7 is brought into the reverse blocking state. The reverse recovering current is limited by the resistor 5. Thus, the reverse recovery is performed slowly, and the voltage fluctuation across the regenerating diode 7 becomes soft. Therefore, noises, which erroneously ignite the electrostatic induction thyristor 1, are not generated.

Title: Frequency synthesizer
Inventor: OKAMOTO KAZUTOSHI
IPC: H03B28/00
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To provide a frequency synthesizer that quickens switching of frequencies. SOLUTION: A phase comparator means 3 compares a phase of a signal obtained by frequency-dividing an oscillated signal from a voltage controlled oscillator means 1 at a frequency divider means 9 with a phase of a reference frequency signal from a reference signal generating means 10 and provides an output of a phase voltage in a direction of decreasing a phase difference. A filter means 5 eliminates a high frequency component from an output signal of the phase comparator means 3 and the result is given to the voltage controlled oscillator means 1 as a control voltage. A voltage setting means 100 inactivates an output signal of the filter means 5 when an output frequency is selected and sets a voltage within a locking range of the PLL to the voltage controlled oscillation means 1 as its control voltage.  Thus, the locking of the frequency after the output signal of the filter means 5 is effective is locked quickly and the switching of frequencies is quickened.

IPC: B29C45/33
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To easily correspond even with a design of a wide range of a thick- walled part by low gas pressure by injecting gas into a cavity before or while a mold is closed and compressed and lowering compression pressure after the completion of mold closing compression and allowing the gas to flow to the periphery of a thickwalled rib part. SOLUTION: In such a state that a mold 2 is slightly opened, a molten resin 3 is injected into a cavity 1 from the resin gate by an injection nozzle 20 and compressed gas is injected into the cavity from a gas injection port. Next, after the mold 2 is closed and compression is completed, compression pressure falls and the gas is allowed to flow to the periphery of the thick-walled rib part 11. After the necessary cooling of a molded product 10, the mold 2 is opened to take out the molded product 10. Therefore, the gas can be certainly introduced even into the thick-walled part of the peripheral part of molded product 10 remotely separated from a gas injection port and gas pressure can be allowed to effectively act on all parts of the continuous thick-walled part of a rib.  By this constitution, this method can easily correspond even to a design of a wide range of a thick-walled part by low gas pressure.
