Title: Breaker with transistor
Inventor: KURUSU YUKIHIRO
IPC: H03K17/62
Filed: 1982-04-13
Abstract: PURPOSE:To limit the number of power supplys for supplying base current to the number of phases, by connecting the emitter and collector sides of transistors (TRs) of each phase to a power supply and a load respectively, and connecting a common base power supply to the bases of the TRs of each phase. CONSTITUTION:An AC power supply is connected to loads 8, 15 in parallel through parallel circuits consisting of diodes 2, 5, 9, 12 and TRs 3, 6, 10, 13 respectively. A common base power supply 16 is connected to the TRs 3, 10 through base signal controlling circuits 4, 11 respectively and a common base power supply 17 is connected to the TRs 6, 13 through base signal controlling circuits 7, 14 respectively. In said circuit, the emitters of the U-phase TRs 3, 10 are the same potential at nodes U1, U2, i.e. a node U, so that only one base power supply is required for the TRs 3, 10 in common. The same theory can be applied to the V-phase.

Title: Golf tee
Inventor: KURACHI KAZUHITO
IPC: A63B57/10
Filed: 1991-03-25
Abstract: PURPOSE:To cause a golf tee to rapidly degrade with rainwater, etc., and make left tees harmless to the environment because of their biodegradability by molding a mixture obtained by addition of a water soluble plasticizer to polyvinyl alcohol in a specific weight ratio. CONSTITUTION:Polyvinyl alcohol for use in a golf tee should preferably have a low degree of polymerization from the point of view of the degrading property of the tee, since it then has high water solubility: One having a degree of polymerization not more than 1500 is especially desirable. A water soluble plasticizer is used; alcohol groups with high boiling points such as glycerol and ethylene are best suited for the plasticizer. The plasticizer is added to the polyvinyl alcohol by 1 to 100wt.% and preferably within the range of 3.0 to 20wt.%. The golf tee is manufactured by adding an additive such as water to the polyvinyl alcohol and the water soluble plasticizer when needed, and molding a mixture which is obtained by kneading of them. Because polyvinyl alcohol and glycerol are biodegradable, they biodegrate in the environment and so do not pollute the environment.

Title: Tripod universal joint
Inventor: OKADA MAKOTO
IPC: F16D3/205
Filed: 1991-03-25
Abstract: PURPOSE:To reduce thrust force in a tripod universal joint. CONSTITUTION:In the case where a universal joint secures a joint angle for transmitting torque, an inside roller 32 and an outside roller 34 which compose a roller member 3 severally make relative movement toward a tripod shaft through the first and the second needle bearings 31, 33, and relatively rotate. The moving and rotating quantities as the whole of the roller member 3 are thereby broken up into both the rollers 32, 34 and the first and the second needle bearings 31, 33. Thus the possibility of the occurrence of the skew in the first and the second needle bearings 31, 33 can be reduced, and even if the skew occurs, its extent is small. Frictional resistance following after the occurrence of the skew therefore decreases to reduce thrust force.

Abstract: PURPOSE: To reduce the occupying area of vent ports provided at the upper and lower front surfaces of an air conditioner body and to improve the external appearance by sending cold air from the upper port at the time of cooling or heating and sending warm air from the lower port at the time of heating. CONSTITUTION: At the time of cooling, a first auxiliary vent passage 9 is closed by a first damper 6, a second auxiliary vent passage 2 is opened by a second damper 4, the air is sucked from the passage 2, and cold air is sent from an upper vent port 8 into a room by a first supply fan 7. At the time of heating, the passage 9 is opened by the damper 6, the passage 2 is closed by the damper 4, and warm air is sucked from the passage 9, and sent from a lower vent port 12 into the room by a second supply fan 11. Thus, the ports provided at the upper and lower front surfaces of the body 1 are only a cooling air outlet 8 and a heating air outlet 12, the occupying area of the front surface of the body 1 by the ports 8, 12 is reduced, and hence the external appearance is improved.

Abstract: PROBLEM TO BE SOLVED: To prevent a directional antenna whose receiving quality is deteriorated from being selected as a new directional antenna for communication by measuring the receiving quality of the plural directional antennas of a radio terminal and selecting the new directional antenna for communication based on the measure result. SOLUTION: A signal from a base station 32 is received by a directional antenna 311b, and a bit error ratio is measured by a reception signal bit error ratio measuring equipment 313. When the measured bit error ratio is deteriorated below a constant threshold value, and the deterioration of the bit error ratio is continued even after the lapse of a constant time, a mobile station 31 judges that diversity switching in the base station 32 fails, and the directional antenna for communication for the mobile station 31 is switched from the antenna 311b to one of directional antennas 311a and 311c-311f based on the measured result being at the measured reception level by controlling a directional antenna for communication selection switch 312 by a directional antenna selection switch controlling part 316.

IPC: F04C18/344
Filed: 1980-05-08
Abstract: PURPOSE: To reduce sucking loss and power consumption by a method wherein a rotor is arranged within a cylinder with a single axial sealing section formed between them so that the throat dimension is increased, the phenomenon of overcompression is controlled and a large sized sucking hole is provided.  
     CONSTITUTION: The rotary compressor is provided with the circular rotor 1 having a pair of vanes 2 slidably fitted in slots 3 in the rotor and a cylinder 4 within which the rotor 1 is disposed with the single axial sealing section 5 formed between them. With the above structure, in case where the angle between a line connecting the center O' of the rotor 1 to a discharge hole 6 and a line connecting the center O' to the axial sealing section 5 is equal to the conventional angle θ, it is possible to make the throat dimension S larger. Hence, the phenomenon of overcompression which has hitherto taken place can be controlled and the input can be reduced without enlarging the nondischarge section. Further, since the sucking hole 7 can be enlarged, the sucking loss and the power consumption of the compressor can be reduced.

Title: Output circuit
IPC: H03K19/00
Filed: 1992-03-18
Abstract: PURPOSE:To suppress the average value of a load current and to suppress the instantaneous value of the load current by a method wherein the ON time of an output transistor is reduced to a required minimum and a load is charged by means of an intermediate potential before data is output. CONSTITUTION:The time in which a reset signal phiIR is changed from a first logic to a second logic is delayed at least until output data is decided. In addition, after a load has been driven by means of an intermediate potential between a high-potential-side power supply VCC and a low-potential-side power supply VSS, the load is driven by the high-potential-side power supply VCC or the low- potential-side power supply VSS according to the logic of the output data. Thereby, after the output data has been decided, the load is driven by the high- potential-side power supply VCC or the low-potential-side power supply. As a result, it is possible to avoid that the load is driven uselessly and to suppress the average value of a load current. In addition, since the load is driven in advance by means of the intermediate potential, the instantaneous value of the load current can be suppressed by means of a small potential difference from the intermediate potential up to the high-potential-side power supply VCC (or the lower-potential-side power supply VSS).

Filed: 1986-03-18
Abstract: PURPOSE:To enhance the heat stability of an electrolyte, and to increase storage life and charge-discharge performance when used as a secondary battery by using dicyclic tertiary amine as an additive. CONSTITUTION:A battery has a positive electrode and a negative electrode comprising lithium or lithium alloy and uses a lithium salt of Lewis acid indicated in the formula I as a solute and an organic solvent. An organic electrolyte added with dicyclic tertiary amine indicated in the formula II is used. Since increase in the content of the additive more stabilizes the electrolyte, the larger content of the additive is preferable. However, the larger content of the additive causes decrease in conductivity and in charge-discharge performance preferable content of the additive is 0.05-2 times in mol based on the lithium salt of Lewis acid indicated in the formula I.
