Inventor: TACHIBANA SEISHI
IPC: C22C1/02
Filed: 1980-06-04
Abstract: PURPOSE: To make molten metal surely fine without causing a change with the passage of time by combining the diffusibility of a high m.p. boride predominant at high temp. with the action of a high m.p. compound such as a nitride.  
     CONSTITUTION: The boride of an alkaline earth metal, a rare earth metal or a peritectic reaction type inorg. element shows the capacity of making a cast structure fine at high temp. By adding the boride to molten metal together with a high m.p. compound such as the nitride or the acetylene compound of an alkaline earth meral or a peritectic reaction type inorg. element, the whole  molten metal is cleaned by dehydrogenation and deoxidation caused by the  thermal decomposition of the compounds. Accordingly, the effect of making a  cast structure fine is improved to make a cast structure surely fine without causing a change with the passage of time, and a high grade casting free from a  flaw is obtd. The used boride is a self-diffusion type boride such as BaB 6  or  CaB 6  or a potential diffusion type boride such as Mg 3 B 2 .

Title: Viterbi detection method for differential phase modulated wave
Inventor: ADACHI FUMIYUKI
IPC: H04L27/22
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To obtain the same characteristic as conventional delay detection Viterbi decoding with a small arithmetic operation amount. SOLUTION: An input difference phase modulation signal is sampled by its symbol period (13), its sampled output zs is delay-detected (14), its detection output Δϕn ' is fed to a D symbol delay circuit 18 and to a differential coder 15, in which the signal is coded. The differential coded output ϕn ' is used to apply inverse modulation to the sampled output zs (16), and an obtained phase difference error with respect to the delay detection signal is decoded by a 3Q<-1> state Viterbi decoder (17). In the case of a high Eb /No , a discrimination error of delay detection is scarcely caused, and even when the discrimination error takes place, the error is either of ±2π/M radians, it is not required to conduct MQ<-1> state Viterbi decoding.  A Viterbi decoding output ΔΨn- D' is added to an output of a delay circuit (18) for correction, to obtain a detection output Δϕn- D.

Title: Optical signal reader
Inventor: ODAGI KAZUTOMI
IPC: G11B7/09
Filed: 1985-04-10
Abstract: PURPOSE:To make it possible to prevent the deterioration of sensitivity of a driving section and to increase upper limit value of allowable current of the coil by attaching a ventilable filter to at least one of an enclosure and an enclosure cover. CONSTITUTION:When a driving section including an objective lens 1 and a coil 4 is moving in the direction of driving (a), (b), the driving section exerts effect like a piston and accordingly, the air inside of a container made by the cover 3, the enclosure 7 and the enclosure cover 16 of an objective lens driving device is compressed and expanded. However, due to air permeability of a member for ventilation 5 itself made of porous material, the compression and expansion of the air are relieved and the resonance of the cover 3 of the objective lens driving device in high frequency band is suppressed and resonance sound generated during the action of the objective lens driving device is lowered. As the variation of pressure inside of the container becomes small, the deterioration of sensitivity of the driving section can be prevented and the air permeability of the filter 5 for ventilation can enhance heat radiation effect of the coil 4. Thus, the upper limit value of allowable current of the coil can be increased.

Filed: 1988-03-31
Abstract: PURPOSE:To enable a rapid heating to be performed by a method wherein when an air temperature within a room reaches a predetermined temperature, a hot air blower is changed over to an intermittent operation and it is continued until a floor surface temperature through a floor panel is increased up to a predetermined temperature. CONSTITUTION:When a heating operation is carried out, coolant discharged from a compressor 1 passes through a four-way valve 2, a flow rate adjusting valve 7. The coolant is guided to an indoor heat exchanger 3 and then hot air is blown into a room. In addition, heat is radiated at a floor heating panel 4 so as to perform a floor heating operation. The coolant passes through a check valve 12, an expansion valve 5 and an outdoor heat exchanger 6 and then it passes through the four-way valve 2 and returns to a compressor 1, and the coolant circulates. When an increasing of an indoor temperature is requested, a flow rate adjusting valve 7 is fully opened by a controlling means 10. The amount of radiation at the indoor heat exchanger is increased until it reaches the predetermined temperature so as to perform a hot air heating. Then, a temperature sensor 9 mounted at the floor heating panel 4 senses that an indoor air temperature reaches the predetermined temperature, a flow rate adjusting valve 7 is closed by the controlling means 10 so as to terminate a hot air heating operation at the indoor heat exchanger 3. The coolant flows to a branch pipe provided with a check valve 11 and continues to perform a floor heating with a floor heating panel 4.

Title: Vane pump
Inventor: KAWABATA MINORU
IPC: F04C15/00
Filed: 1981-05-19
Abstract: PURPOSE:To reduce pulsation of pressure in a pump, by stabilizing the internal leakage of pump at any angular position of a rotor through provision of leakage controlling grooves in contact surfaces between the rotor and side plates, and thereby preventing fluctuation of discharge quantity of the pump due to leakage of fluid inside the pump. CONSTITUTION:When the discharge pressure of a pump is raised, pressure fluid in pressure grooves 37, 38 is leaked to annular leakage controlling grooves 40, 41 through a side clearance formed between a rotor 22 and side plates 15, 16 and then leaked radially toward suction ports 25, 26. In case that the angular range of leakage at the suction ports 25, 26 is small, the amount of fluid leaked from the suction ports 25, 26 to the leakage controlling grooves 40, 41 is increased. On the other hand, in case that the angular range of leakage is large, the amount of fluid leaked is decreased. Thus, since the amount of fluid leaked from the leakage controlling grooves 40, 41 to the suction ports 25, 26 is stabilized at any position of the rotor 22, fluctuation of discharge quantity due to leakage of fluid inside the pump can be minimized, so that pulsation of pressure can be reduced.

Title: Thermosensitive transfer material
Inventor: MIMURA TAKASHI
IPC: B41M5/44
Filed: 1988-03-30
Abstract: PURPOSE:To form a non-repellent and uniformly strong coat and thereby eliminate back surface transfer of an ink layer without sticking by providing a protective layer consisting of a mixture of swelling inorganic stratified silicate, water-dispersant thermoplastic resin and organopolysiloxane of a specific weight ratio. CONSTITUTION:Swelling inorganic stratified silicate (a) is used as an inorganic coating component. In a protective layer, the silicate exists in the form of fine particles formed at least by partial interlayer separation using the swelling property. Water-soluble or water-dispersant thermoplastic resin (b) is thermoplastic resin which is dissolved, emulsified and suspended in water. Water-soluble or water-dispersant organopolysiloxane (c) is required to have a weight ratio of 1/20 to 5/1 for a/c and also 5/1 to 1/40 for a+c/b. This is because of an increase in coat fragility which is not desirable in terms of strength, if the weight ratio is larger than 5/1. If the weight ratio is smaller than 1/40, the sticking preventive effects are insufficient as an undesirable result.
