Title: Elastic surface wave equipment
Inventor: MORIMOTO MIKIO
IPC: H03H9/145
Filed: 1980-03-04
Abstract: PURPOSE:To make it possible to easily correct an asymmetrical property in the passing band, by providing an impedance converting circuit by which is impedance which has viewed the electric power source side and the load side from the elastic surface wave element is made lower than the internal impedance of the elastic surfae wave element. CONSTITUTION:The impedance converting circuit constituted of resistors R1-R4 is added between the elastic power source impedance or the load impedance, and the elastic surface wave element (part shown in the broken line). Therefore, as an elastic surface wave element whose radiation resistance has been designed to 50OMEGA in the center frequency, when the passing band characteristic is measured concerning 4 kinds of Rx=10OMEGA, 50OMEGA, 75OMEGA and 1,000OMEGA (Rx shows the external impedance which has viewed the outside from the element side at a spot of the terminal in a state that the impedance has been ended), in case of Rx=50OMEGA, the loss becomes minimum since it is matched with the element, and the asymmetrical property in the passing band is greatly distorted. The asymmetrical property is increased when Rx is 75OMEGA and 1,000OMEGA. In case of Rx=10OMEGA, it nearly conforms with the calculation value, and the symmetrical property becomes satisfactory.

Title: Vaporization cooling type electric apparatus
Inventor: ENDO MICHITADA
IPC: H01F27/18
Filed: 1985-02-15
Abstract: PURPOSE:To make it possible to dispense with accessories of a pump for exhausting a non-condensable gas and thereby to reduce an accessories loss by a construction wherein a piping is laid through a refrigerant vessel, an auxiliary refrigerant changing in phase is enclosed in the piping, and a flexible vessel provided inside the refrigerant vessel is made to communicate with a condenser and the main vessel through a pipeline having a check valve. CONSTITUTION:When a refrigerant liquid 3 is heated and a refrigerant vapor 10 is generated therefrom, part of the vapor flows into a condenser member 5b and is liquefied therein, and the liquefied refrigerant returns to a lower head 5a and then to the bottom part of the main vessel 2. The heat of the vapor 10 flowing into the condenser member 5b heats an auxiliary refrigerant 12 in a piping 11. Therefore the vapor pressure in the piping 11 increases gradually and presses the working top 15 of a flexible vessel 14, whereby the flexible vessel 14 is contracted gradually. With the exhaustion of the gas inside a condenser 5, the vapor 10 flows again from the main vessel 2 side into the condenser 5. Simultaneously when the radiation of heat from the condenser 5 is reopened, the vapor pressure inside the piping rises again, and thereby a gas 4 sent into the flexible vessel 14 can be returned again into the main vessel 2 through a second pipeline 17b.

Title: Combustion device
Inventor: ITO MASARU
IPC: F23Q3/00
Filed: 1986-02-07
Abstract: PURPOSE:To prevent a flame from being splashed and white smoke from being generated due to a delay in ignition by a method wherein an entire size of an ignition port is not reduced, but divided into a plurality of sections and an opening area of each of the divided ignition ports is made larger than small holes acting as flame ports of other portions. CONSTITUTION:Ignition ports 10A and 10B having a larger opening area than that of a small hole 9 acting as a flame port are arranged. As a gasification cylinder 2 is heated up to a desired temperature and mixture gas is injected from the small holes 9 and ignition ports 10A and 10B, the mixture gas is ignited by an electrical discharging sent from an ignition electrode 14 toward a center of the ignition port i.e. a partition column 20 and then burns. At this time, a flow speed of the mixture gas injected from the divided ignition ports 10A and 10B is delayed as compared with that of ignition from a signal large area. Due to this face, a splashing of flame caused by a local high speed is not generated and at the same time the partition column 20 may act as a flame holding body, resulting in that a delay in ignition caused by the splashing of flame in case of ignition can be prevented and the white smoke at the time of ignition caused by a flowing-out of non-ignited mixture gas can be prevented from being generated. Further, since the ignition port is divided into several sections with the partition column 20, an over-heating of the metallic net 12 at a central part of the ignition port can be prevented and a durability of the unit can be ensured over a larger time.
