IPC: H01Q3/30
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To make increase the reception gain of an antenna easy and to easily adjust the beam direction angle of the antenna by providing a parasitic element between a pair of separated microstrip lines to electromagnetically resonate them. SOLUTION: A pair of microstrip lines 2 are constituted by applying a conductive foil onto the upper surface of an antenna substrate 1, and the microstrip lines 2 are mutually separately provided on the antenna substrate 1 and respectively linearly provided with narrow feeding parts 3 and wide resonating parts 4. A parasitic element (electromagnetic coupling resonator) 7 is formed by applying a conductive foil 9 onto the upper surface of a dielectric substrate 8, arranged and fixed over the resonating parts 4 of the microstrip lines 2 on the upper surface of the antenna substrate 1.  Thus, the dielectric substrate 8 of the parasitic element 7 is interposed between the resonating part 4 of the microstrip line 2 and the conductive foil 9 of the parasitic element 7, and the respective resonating parts 4 of the microstrip lines 2 and the conductive foil 9 of the parasitic element 7 are made to resonate electromagnetically for about half a wavelength.

Title: Transmitter and receiver
IPC: H04R3/00
Filed: 1992-03-24
Abstract: PURPOSE:To radiate the amplified sound wave of the transmitter without causing howling by minimizing the amplitude of the sound wave at a receiver position where the sound wave in a medium is received by interference among sound waves radiated at respective positions of the transmitter. CONSTITUTION:The sound wave received by the receiver 1 is amplified by an amplifier 2 for the receiver, passed through amplifiers 3a-3c, and sound waves 5a-5c are radiated into the medium by transmitters 4a-4c. At this time, the amplification factors and phase characteristics of the amplifiers 3a-3c for the transmitters are varied so that the sum of the sound waves at the position of the receiver 1 becomes 0, and then the sound waves outputted by the transmitters 4a-4c are not received by the receiver 1. Consequently, the receiver 1 can receive only the sound wave 9 from an external sound source 8 except the transmitters at all times. For the purpose, the sensitivity of the receiver 1 is increased to obtain a long distance between the sound source 8 and the receiver 1, and speeches of persons in a wide area can be received by one receiver at a conference, etc.

Title: Initial seek system
Inventor: KOBAYASHI KYUKICHI
IPC: G11B21/08
Filed: 1989-03-20
Abstract: PURPOSE:To accurately perform the sensing of an external force by setting targeted speed in initial seek so as to become less than the targeted speed in actual read/write. CONSTITUTION:A servo circuit 10 and a servo object 20 are provided, and the servo object 20 is equipped with a head 21, a voice coil motor 22, and a disk 23. The servo circuit 10 performs initial seek control when seek control in ordinary read/write is performed and a magnetic disk device is started up.

IPC: F23L17/16
Filed: 1979-05-30
Abstract: PURPOSE: To constantly discharge comfortable hot air from a hot-air discharge port by a method wherein the noxious gaseous components, stink, soot, and the like contained in the heating air having been burnt at a combustion portion are removed by a catalyst layer.  
     CONSTITUTION: At the time of operation, a knob 4 is first operated to bring an ignition mechanism and a combustion portion 3 of a combustor into operation. Simultaneously, a motor 18 and a fan 19 connected thereof start rotating. Infrared rays radiated from the combustion portion 3 permeate through the wall of a duct 14, and are reflected by a reflecting plate 10, radiating heat to the front side of a main body 1. On the other hand, the heating air having been heated at the combustion portion 3 is guided through the duct 14 to a catalyst layer 13, where it is deprived of noxious components, stink, soot, and the like, and then flows into an air passage 11. By the rotation of the fan 19, the heating air is mixed with the outside air fed from an intake port 5 to form hot air, which is discharged from a discharge port 6. A portion of the hot air is directed into louvers 23.

Title: Semiconductor integrated circuit
Inventor: KUME EIJI
IPC: G11C11/409
Filed: 1989-03-20
Abstract: PURPOSE:To obtain a highly integrated semiconductor integrated circuit operating at high speed and at low energy consumption by using a transistor (TR) at a low threshold voltage for a circuit with the low voltage amplitude out of the circuits having the plural voltage amplitudes. CONSTITUTION:When the voltage of a word line W0 is set from VSS (0V) to VDH (1.5V), information accumulated in an accumulated capacitor CS is read to a data line D. Next, when a P1P is set from VDL (1.0V) to the VSS (0V) and a P1N is set from the VSS (0V) to the VDL (1.0V), sense amplifier driving TRs QP and QN are turned on, and a sense amplifier driving line CSP is changed from HVC (0.5V) to the VDL (1.0V), and a CSN is changed from the HVC (0.5V) to the VSS (0V). At such a time, since the sense amplifier uses TRs Q1' to Q4' at the low threshold voltage, the voltage between a gate and a source sufficiently exceeds the threshold voltage, the TR of the sense amplifier is sufficiently turned on, and the signal voltage of the data line can be sufficiently amplified. Thus the high-speed operation and energy consumption reduction are attained.

Filed: 1985-04-01
Abstract: PURPOSE:To enabe non-step speed change to be performed on the positive and negative rotations of a rotor, by arranging the pressure-fitted point of the rotor to be variable on the end face of a stator. CONSTITUTION:When lead wires 11-13 are connected to a high-frequency power source and a rotor 14 is placed at out-of-central-point positions on the end face of a cantilever type oscillator 9, then the rotor 14 is energetically rotated, and rotational output is obtained from an axle 15. When a knob 17 is turned to the maximum and the pressure-fitted point of the rotor 14 is arranged near one end side in the direction of the width of the cantilever type oscillator 9, then the rotational speed is increased. As the knob 17 is reversely turned, the rotational speed is gradually reduced, and when the pressure-fitted point of the rotor 14 is shifted up to the center in the direction of the width of the cantilever type oscillator 9, then the rotation is stopped. When the knob 17 is continuously turned in the same direction further, then the axle 15 starts rotating reversely.
