Title: Radio receiver and method for radio receiver
Inventor: MANKU TAJINDER
IPC: H04L27/233
Filed: 1998-08-13
Abstract: PROBLEM TO BE SOLVED: To provide a radio receiver which has a zero-IF direct down converter which does not respond to leak between a local oscillator (LO)-RF (radio frequency) and the mismatching of the device and a method for the radio receiver. SOLUTION: In this system, a radio frequency signal is divided into two arms that have mixers M1 and M2 separately. Each of the mixers M1 and M2 has two inputs, i.e., a local oscillator signal which is undergone phase modulation and a RF information signal. The local oscillator signal that is undergone phase modulation between the arms has 90 degrees phase shift, difference. Output signals of both mixers M1 and M2 are subtracted, and an output signal of the subtracter A1 is mixed with a phase modulation signal by a 3rd mixer M3. An output signal from the mixer M3 represents a baseband signal. Next, a lowpass filter 18 eliminates an unneeded signal.

Title: Write power circuit for magnetic recording
Inventor: NAKAMOTO HIDENOBU
IPC: G11B5/09
Filed: 1989-09-04
Abstract: PURPOSE:To reduce and simplify a circuit scale by varying a write reference voltage in correspondence with the variance of a resistance value in a write head. CONSTITUTION:Since MPU 8 gives an analog voltage value DAC corresponding to the standard resistance value of the write head 7 to an operand amplifier 21 through a D/A converter 9, a specified write current can be obtained in spite of the variance of the resistance value of the write head 7. In such a case, the circuit scale is prevented from increasing because plural write reference voltage sources are not necessary to be prepared for respective write heads 7. Furthermore, the trouble of adjustment is eliminated because the load resistances 5A and 5B of the write head 7 are not necessary to be adjusted for respective makers when the heads of plural head manufacture makers are used. Thus, cost can be reduced because the circuit scale can be reduced and the specification of the resistance value deviation of the write head 7 can be relieved.

Title: Production method of cadmium electrode
Inventor: KONISHI MAKOTO
IPC: B22F5/00
Filed: 1982-12-23
Abstract: PURPOSE:To prevent a nickel sintered body from being eroded in a cadmium nitrate solution and improve the voltage characteristics during discharging by sintering a sintered nickel substrate in the reducing gas atmosphere and naturally cooling the substrate in the air after it has been cooled to a specific temperature. CONSTITUTION:Carbonyl nickel powder is sintered in the reducing atmosphere (about 800 deg.C), and after the sintering is completed and when a substrate is cooled to a temperature of 700-300 deg.C, it is naturally cooled in the air to form a nickel oxide layer with acid resistance on the surface of the sintered body. Accordingly, the nickel sintered body can be prevented from being eroded by an acid cadmium nitrate solution when the nickel sintered body is immersed in the cadmium solution and is electrolytically reduced and is filled with an active material by use of a simple method, thus the discharge characteristics of a Ni- Cd cell can be improved.

Title: Rod for reinforcing concrete
Inventor: HOSOYA TAKE
IPC: B28B23/04
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To obtain the subject rod by impregnating multifilament yarns with an alkali-insoluble resin followed by squeezing the resultant yarns at specified intervals prior to entirely curing the resin to vary the resin pickup and rigidity of the yarns so as to produce reinforced concrete of good workability and diversified mechanical strength. SOLUTION: This rod for reinforcing concrete is obtained by the following practice: multifilament yarns are impregnated with an alkali-insoluble resin followed by squeezing the resultant yarns at specified intervals prior to entirely curing the resin to develop portions 1 of higher resin pickup and portions 2 of lower resin pickup (or no resin pickup due to resin melting) and vary the rigidity of the yarns, and the resultant filament yarns are cut to pieces each 8-10 mm in length. The pieces of the rod thus obtained, when kneaded with concrete, are bent at points of lower resin pickup and lower rigidity, resulting in development of anchoring effect and thereby enabling energy absorption. Alternatively, a rod similar to the above rod can be obtained by impregnating multifilament yarns with a water-soluble or alkali-soluble resin and an alkali- insoluble resin at specified intervals.

Title: Temperature controller for exhaust-emission control catalyst for internal combustion engine
Inventor: NAKAMURA KANEHITO
IPC: F01N3/24
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To set the temperature of an exhaust-emission control catalyst falling within its activation temperature range and thus improve its exhaust-emission control performance by controlling the temperature of exhaust emissions without deteriorating the drive feeling of the vehicle. SOLUTION: When the temperature of an exhaust-emission control catalyst falls below its activation temperature range, the engine is operated at lower speed and higher torque by increasing the quantity of fuel supplied thereto on the basis of a temperature-up fuel supply quantity map and reducing the transmission gear ratio on the basis of a temperature-up transmission gear ratio map for correction in a degree that the engine torque does not exceed its tolerance limit value, to thereby increase the temperature of exhaust emissions and thus the catalyst temperature into its activation temperature range through steps 102, 103 and 105.  When the catalyst temperature rises above its activation temperature range, the engine is operated at higher speed and lower torque by decreasing the fuel supply quantity and increasing the transmission gear ratio on the basis of a temperature-down transmission gear ratio map for correction in a degree that the engine speed does not exceed its tolerance limit value, to thereby decrease the exhaust emission temperature and thus the catalyst temperature into its activation temperature range through steps 102, 104 and 106.
