Title: Production method of crt
Inventor: SHIOTANI MITSUYUKI
IPC: H01J9/00
Filed: 1981-05-12
Abstract: PURPOSE:To drastically reduce unnecessary electrons generated in a tube, to prevent a cathode and a heater from being damaged by sparks, and to improve a withstand voltage characteristic by preventing carbonate powders generated under high-frequency heating of an electrode of an electron gun from being scattered. CONSTITUTION:It was made clear that a scatter of carbonate powders 14 varied in accordance with frequencies of a high-frequency heating unit while heating an electrode. That is, when the high-frequency heating was conducted at an oscillating frequency of 300kHz or less, unnecessary electron sources 16 were acknowledged to attach to electrodes in not less than half of CRTs, and the lower the oscillating frequency was decreased, the more were the carbonate powders 14 scattered. On the other hand, when the oscillating frequency was kept at about 350-550KHz, a scatter of the carbonate powders 14 rarely occured. By preventing the carbonate powders of the cathode from being scattered, unnecessary electrons generated in the tube are reduced drastically, damages of the cathode and the heater due to sparks are prevented, and the CRT with an excellent withstand voltage characteristic can be obtained.

Filed: 1979-06-11
Abstract: PURPOSE:To make it possible to measure the distance between a radar and an object material even if the actual relative speed between them is 0, by using a width variable waveguide to change the course length between them. CONSTITUTION:Transmission wave ET is transmitted from transmission part 2 of diplex-system radar 1, and reflection wave ER from an object material is received, and a Doppler signal is taken out through a mixer diode.

Filed: 1984-04-12
Abstract: PURPOSE:To keep the pressure in an air-conditioned room positive and consequently enable to realize comfortable ventilation by a structure wherein an opening area communicating with the negative pressure side of an outdoor side ventilating air circuit is made smaller than that of an indoor side ventilating air circuit. CONSTITUTION:When a switch in an operating unit 14 is set to a ventilation mode, a motor 30 is energized for a certain period of time and consequently a damper 24 is open so that the negative pressure side of an indoor side air circuit 3 communicates through an opening 22 with an outdoor side air circuit 4, resulting in flowing a part of the circuit 4 (the fresh air) in the circuit 3 or leading the fresh air in the indoor side. On the other hand, the negative pressure side of the circuit 4 communicates through an opening 23 with the circuit 3, resulting in flowing a part of the circuit 3 (the indoor air) in the circuit 4 or exhausting the indoor air to the outdoor side. At the case, because the area of the opening 22 is larger than that of the opening 23, even though the static pressure on the negative pressure side of a fan 6 is higher than that of a fan 5, the amount of the fresh air led in the circuit 3 is larger than that of the indoor air exhausted to the circuit 4, resulting in keeping the pressure in an air-conditioned room positive and realizing comfortable ventilation.

Title: Method for decarbonizing molten base steel for stainless steel under reduced pressure
Inventor: SAKURATANI TOSHIKAZU
IPC: C21C7/10
Filed: 1988-03-29
Abstract: PURPOSE:To effectively improve decarbonizing efficiency in low carbon range without any oxidized loss of Cr by blowing low melting point slag composition powder into molten base steel for Cr-contained stainless steel by using oxygen-contained gas under reduced pressure. CONSTITUTION:In RH degassing apparatus, at the time of decarbonization treating the molten base steel for the stainless steel under reduced pressure atmosphere, the low melting point slag composition is blown into the molten steel 3 from tuyere 2 arranged at below the molten steel 3 surface in the reduced pressure vessel 1 by using O2-contained gas as carrier gas. By this method, in case the molten steel 3 is the low carbon stainless steel, Cr in the molten steel 3 is oxidized with O2 gas to form solid-state Cr2O3 just above tuyere 2. This Cr2O3 grain is absorbed and melted into the slag drip formed, by which the low melting point slag powder introduced in the molten steel 3 at the same time is melted, and shifted in the molten steel 3, to expose to the reduced pressure atmosphere. Then, as reaction velocity of O in liquid Cr2O3 with C in the molten steel 3 is extremely quick, the reduction of Cr2O3 with C is perfectly progressed during short time, which the slag drip stays in the molten steel 3.

Abstract: PURPOSE:To shorten a starting time and to delete power consumption by providing a heat exchanger in a regenerator of an absorption refrigerant and providing a circuit for selectively connecting the exchanger to a coolant circuit of a fuel cell at the time of starting with the cell. CONSTITUTION:Coolant of a fuel cell FC is connected to a heat exchanger E4 provided in a regenerator R of an absorption type refrigerator through a circuit L3. In the case of normally operating with a fuel cell FC, the circuit L3 is not used by stopping a pump P2 or shutting OFF via a valve, etc. On the other hand, at the time of starting, coolant is guided to the exchanger E4 of the regenerator R. Accordingly, the coolant is always heated by a heat source HS in the exchanger E4, heat exchanged with lithium bromide solution held at a high temperature, raised at its temperature, and then guided to a stream drum S. As a result, power consumption of an electric heater H at the time of starting is deleted. Thus, the starting time can be shortened, and power consumption can be deleted.
