Patent JP-H02290475-A (JP)
Title: Heat pump type air conditioner
Inventor: ENDO KOICHI
IPC: F25B27/02
Filed: 1989-04-28
Abstract: PURPOSE:To make a heating capacity high by a construction wherein a refrigerant piping connecting first and second indoor heat exchangers is provided for a refrigerant heater through which hot water heated by a waste heat of an engine is made to flow and the refrigerant flowing through the refrigerant piping is heated by the refrigerant heater at the time of heating. CONSTITUTION:In a heating operation, an indoor space is heated by a heat radiated when a refrigerant is condensed and liquefied in first and second indoor heat exchangers 4a and 4b. The refrigerant condensed and liquefied again by the second indoor heat exchanger 4b is expanded under a reduced pressure to be an atomized refrigerant in a pressure-reducing device 7 and it is sent to an outdoor heat exchanger 8, wherein it is evaporated. The evaporated refrigerant passes again through a selector valve 3 and is subjected to gas-liquid separation in an accumulator 9, and a gas refrigerant led out therefrom returns to a compressor 2. Besides, cooling water of an engine 1 is heated to be hot water by a waste heat of a waste heat collecting device 10 and sent to a refrigerant heater 11, and after heating the refrigerant therein, the hot water passes through a thermo-valve 12. When the temperature of the hot water is a set temperature of the thermo-valve 12 or above, the hot water flows to a radiator 13, radiates the heat therein and then returns to the engine 1, while it returns to the engine 1 directly, not flowing to the radiator 13, when the temperature thereof is below the set temperature.

Title: Method for controlling hydraulic apparatus for shifting mold of injection molder
Inventor: YOKOTA AKIRA
IPC: F15B11/00
Filed: 1986-05-15
Abstract: PURPOSE:To soften the shock at stopping and at the same time improve the accuracy of the stop position of a mold opening and closing device by a method wherein the oil pressures in the feed side oil chamber and in the return side oil chamber of a mold shifting oil pressure apparatus, which controls the actuation of the mold opening and closing device, is released just before the stopping of the mold opening and closing device and, after that, the mold opening and closing device is stopped completely. CONSTITUTION:The kinetic energy of shifting members such as a mold and the like is absorbed by the oil pressure in the return side oil chamber 28 of a mold shifting oil pressure apparatus 22 during the deceleration of mold shifting speed. When the mold shifting speed lowers to the value preset just before the stopping of a mold, the oil pressures in the return side oil chamber and in the feed side oil chamber 30 are simultaneously released, thus keeping the mold shifting at very slow speed due to the inertial of the mold. When the mold reaches its stop position in the state just mentioned above, the feed side oil chamber and the return side oil chamber of the mold shifting oil pressure apparatus are closed and consequently the shifting of the mold is stopped. In this case, the action of the oil pressure in the return side oil chamber is to absorb only the inertia of the mold and the like, which shift at very slow speed and no more, resulting in no abrupt oil pressure rise. Consequently, the shockless and smooth stopping is made possible and further the accuracy of the stop position of the mold is also improved.

Title: Digital television broadcast receiver
Inventor: TAKAYAMA AKIRA
IPC: H04N5/44
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To put both a fundamental wave and higher harmonics generated from an oscillator at the time of digital signal demodulation outside a reception band, to eliminate a band-pass filter, and to simplify the configuration by setting the frequency of an intermediate frequency signal to be higher than the highest frequency of a reception signal, and demodulating the intermediate frequency signal by a digital signal demodulator. SOLUTION: A digital tuner 1 receives the reception signal of a digital television in a 50-900 MHz band through a band-pass filter 2. A mixing circuit 3 mixes a local transmission signal from a local oscillation circuit 4 to the reception signal, and converts it into an intermediate frequency signal. In this case, intermediate frequencies are set to be higher than the highest frequency of the reception signal, for example, to be 1200 MHz. Then, the oscillation frequencies of the local oscillation circuit 4 range from 1255 to 1285 MHz. A digital signal modulator 6 receives the intermediate frequency signal through an output filter having a pass band of 6 MHz, demodulates it with a carrier wave signal of about 1200 MHz from an oscillator 7, and obtains I signal and Q signal base bands.
