Patent JP-H03277944-A (JP)
Title: Circuit for checking optical sensor
Inventor: KOSHIISHI YUKIO
IPC: G01N21/01
Filed: 1990-03-28
Abstract: PURPOSE:To make it possible to perform checking even after the mounting on an apparatus by changing the light emitting amount of a light emitting means in response to an external command, comparing the output of a light receiving means with a specified reference value, and changing the specified reference value in response to the external command. CONSTITUTION:When a control signal CONT1 is set at a high level in a current control circuit 6 on the light emitting side, a transistor Tr is turned OFF, and a light emitting element 1 does not emit light. When the CONT1 is set at a low level, the Tr is turned ON, and the element 1 emits light. When a photodetector 2 is ON in a voltage adjusting circuit 8 on the light receiving side, voltage values are inputted into a comparator 3 in response to the voltage dividing ratio among a resistor R6, a variable resistor VR and a resistor R7. When the variable resistor VR is adjusted, the input voltage value into the comparator 3 can be adjusted. When the levels of control signals CONT2 and CONT3 are changed in a reference value control circuit on the light receiving side, the reference voltage of the comparator 3 is changed. Therefore, when the levels of the signals CONT1 - 3 are changed, the checking can be performed by changing the conditions.

Title: Measurement of wave refractive index of ionosphere and atmospheric gas layer via follow-up of wave propagation route and measurement of relative position between target and observation point
Inventor: KAWAMATA KENICHI
IPC: G01C15/00
Filed: 1994-03-26
Abstract: PURPOSE:To accurately measure the cosine of the critical incident angle of a wave to an ionosphere by following up the wave from the position of a satellite assumed on the basis of a wave propagation time therefrom and the approximate value of a vertical distance between horizontal planes across the satellite and an observation point on the ground. CONSTITUTION:The virtual point P1 of a satellite (point P) is set on the basis of the approximate value of the 3D position of the point P obtained from a wave transmitted from the satellite, and a linear distance between the point P1 and an observation point A on the ground is divided by a flux (u), thereby establishing a wave propagation time pi. Then, a virtual point P'1 is set on a wave propagation route P1CA with length P1DA kept equal to P'1CA, so that a wave from the point P1 can reach in the propagation time P1. Also, the virtual point P2 of the satellite is established, so as to keep route length P2EA equal to P'1CA, thereby obtaining a vertical distance Lzi. between horizontal planes across the point P2 and the observation point A. As a result, a critical incident angle alphaio when a wave passing the route P2EA enters the interface of a wave rectilinear propagation layer and an ionosphere, can be detected, thereby improving the measurement accuracy of the 3D position of the satellite.

Title: Wire dot printing head
Inventor: ANDO KOICHI
IPC: B41J29/00
Filed: 1991-04-12
Abstract: PURPOSE:To prevent a thermal throughput from becoming deteriorated without suspending a printing process by providing a device to detect the temperature of each coil sequentially. CONSTITUTION:If temperature detection data which is output from a buffer is received, a temperature detection device runs an electric current for temperature detection to each coil 13 to detect the coil temperature sequentially. If there is any pin which reaches the level where a detected temperature is equal to the limits of heat resistance, the temperature detection device stops the drive of the pin only without suspending a printing process, and prints a single line of data based on buffer printing data. Further, the device feeds a line and prints the line again by driving another coil 13 at low temperature. During this period, the temperature drops as the coil 13 which reaches the limits of heat resistance remains undriven. Thus the thermal throughput increases significantly due to the continuation of a printing process using a pin at low temperature.

Title: Mca radio communication equipment
Inventor: HIRANO TADAHIKO
IPC: H04W99/00
Filed: 1984-04-20
Abstract: PURPOSE:To read traffic data possessed by an MCA control station at any time by providing a data edition means for editing a traffic data request command and a traffic data reception means for receiving the traffic data transmitted from the MCA control station via a talking channel. CONSTITUTION:When the traffic request command is talking traffic data at present time, a call data edition subroutine is executed. When no reply is obtained from the MCA control station to call, the system transits to a stand-by program 3sec later. A flip-flop 21 of a traffic data reception circuit 20 is set during stand-by. When the flip-flop 21 is set, a radio wave is transmitted intermittently in response to the operation of a pulse generating circuit 24 to prevent the detection of 2sec radio wave intermission. When the time not receiving any traffic data is elapsed for 10sec, the system restores to the stand-by state. In receiving the traffic data, the connection of a talking channel is subjected to the MCA control station within 60sec. When the numeral of the traffic request command is ''11'', voice information is executed from the MCA control station.

Title: Harmonic transmitting and receiving system with high sensitivity
Inventor: HORIGUCHI YUTAKA
IPC: H04B17/00
Filed: 1981-05-25
Abstract: PURPOSE:To obtain a reception system with low cost and high sensitivity without a highly stable oscillator, by transmitting a signal in N-multiplied frequency and a fundamental frequency from a transmission on section, receiving the signal at a reception section, and mixing the signal with a local oscillating frequency for multiplication. CONSTITUTION:In a radio communication in a microwave or milliwave band, the output of an oscillation 1 in a fundamental frequency fs is divided into two, a fundamental  wave route A and a harmonic wave route B, and the electromagnetic waves of the route A are radiated from a fundamental wave transmission antenna 3 and the waves on the route B are multiplied by N and radiated from a harmonic wave transmission antenna 4. The fundamental wave is received at an antenna 5 at the reception section, the wave is converted into an intermediate frequency fIF=fs-fL with a frequency fL from a local oscillator 9 and multiplied by N at a multiplier 11 via a limiter 10. The output of the multiplier 11 is mixed with the output of a reference oscillator 13 in frequency f0 at a mixer 12 for shift and the output frequency fx becomes fx=N(fs-fL)-f0. The harmonic waves are received at an antenna 6 and converted into fIPM=N(fs-fL), mixed with the frequency fx at a mixer 14 and converted into fIPM-fx=f0. High stability can be obtained by selecting the f0 in the VHF band.

Then, the inner electrodes 2 are dissolved by etching. The laminated body is burned again to form an insulating part 4. In succession, the insulating part 4 is polished until the surface of the laminated body is exposed. At this point, insulating parts 4a and 4b are left in the laminated body as they are.
