Title: Printed dipole antenna
Inventor: YOSHIKAWA YUKIHIRO
IPC: H01Q9/28
Filed: 1984-04-10
Abstract: PURPOSE:To improve reception sensitivity characteristics and to obtain symmetrical radiation directivity by connecting a passive element printed on the lengthwise axis of a dipole electrically to the dipole. CONSTITUTION:The radiation field of the antenna is directed in parallel to a dielectric substrate 1 with high-frequency currents which flow from dipoles 2a and 2b to passive elements 7a and 7b through a through hole 8. When the radio wave which has an electric field component E1 parallel to the substrate 1 and an electric field component E2 perpendicular to it arrives in a direction A, only the component E1 is received and the component E2 is not received. Therefore, the output of a coaxial plug 6 is a received current proportional to the amplitude intensity of the component E1 and the reception sensitivity characteristics are improved; and the dipoles 2a and 2b and elements 7a and 7b are symmetrical about the substrate 1 and radiation directivity has an excellent symmetrical pattern.

Title: Speed signal detector
Inventor: TOKASHIKI MUTSUO
IPC: G01P3/48
Filed: 1987-03-27
Abstract: PURPOSE:To simplify a circuit structure and reduce the effect of an output waveform and a power consumption by differentiating a phase A signal and a phase B signal having substantially the same amplitude, output frequencies proportional to the number of revolutions and a 90 deg. phase difference. CONSTITUTION:Differentiating circuits 1 and 2 differentiate sine wave phase A signals and phase B signals and a 90 deg. phase difference outputted from a two-phase type encoder to obtain dA/dt and dB/dt, respectively. A waveform shaping circuit 3 shapes the waveforms of the phase A and phase B signals and makes a 90 deg. changeover command signal and a 180 deg. changeover command signal. Then, by changing over dA/dt and dB/dt at every 90 deg. by a 90 deg. changeover command signal by an analog switch 4, the phase A and the phase B signals are united into an AC waveform with a phase shifted by 45 deg. from those of dA/dt and dB/dt. The AC waveform is changed over at every 180 deg. by the switch 4 in a 180 deg. changeover command circuit to be divided into a positive and a negative. A differential circuit 5 operates so as to amplify a differential voltage between a positive output and a negative output and produces an output proportional to the number of revolutions.

Title: Temperature detector
Inventor: MURAMOTO YUTAKA
IPC: G01D5/245
Filed: 1982-04-30
Abstract: PURPOSE:To enable the precise detection of a temperature in a wide range, by making the oscillation frequency of an oscillator constant irrespective of a change in the temperature, while making the most of the characteristic of the oscillator in the manner that it has a high temperature resolution without being affected by a suspended capacity and the frequency characteristic of an oscillating element. CONSTITUTION:A temperature detector comprises two C-MOS inverters IV1 and IV2, a temperature-sensitive resistance element determining a time constant together with a capacitor C, e.g. a variable resistor connected in parallel with a thermistor Rth, a resistance array Rx, and a protective resistor Rp. In order to make an oscillation frequency fx constant, it is sufficient that a parallel resistance Rpo has a constant value. Since the resistance value Rth of the thermistor changes with a temperature, the resistance value Rx of the resistance array is made to change with the temperature so as to maintain the oscillation frequency at a constant value. Such operations are performed in several times that the difference between the output frequency of an oscillator 10 and the oscillation frequency fo of a reference oscillator is determined and reduced. A resistance value delivered after these operations satisfy a relational formula for the relation between the temperature and the change in the resistance value of the thermistor.

Abstract: PURPOSE:To decompose and treat the organic substance layers on substrates at high vaporization and decomposition rates by intermittingly performing the irradiation of light from light sources on the surfaces of the organic substance layers. CONSTITUTION:Ultraviolet lights from low-pressure mercury-arc lamps 17 are irradiated on the surfaces of the photosensitive resins on wafers 13 in a state that oxygen gas or gas containing oxygen gas has been fed in a chamber 11 through a gas feeding nozzle 20. At the same time, a current is made to flow through a heater 14 and with the wafers 13 heated by the heating of the heater 14 through a susceptor 12, the susceptor 12 is rotated by the driving of a motor 16 and the wafers 13 on the susceptor 12 are rotated along the upper part of the circumference.

Filed: 1983-04-27
Abstract: PURPOSE:To attain a pulse counting with high reliability by counting the ON time and OFF time of the signal generated from a pulse generator and comparing these time count values with each other to confirm whether the pulse component has no error signal. CONSTITUTION:A slit 8 is revolved at a fixed speed together with a wheel, and the pulse widths delivered from photoelectric switches 9a and 9b have the relation T1 T2 T3 T4.
