Title: Recording apparatus
Inventor: NISHITANI KIMIO
IPC: B41J29/50
Filed: 1989-05-26
Abstract: PURPOSE:To detect the presence of the feed of paper and the width of paper by one detector by discriminating the width of a medium to be recorded on the basis of the output signal of a detection means obtained when a reflecting type photosensor is moved along with a recording head. CONSTITUTION:When paper 5 is present, the quantity of the reflected light received by a photosensor 1 is reduced and the output voltage of the photosensor 1 becomes higher than the reference voltage of an interface amplifier 9 and the output of the amplifier 9 becomes a 'High' level. Therefore, a microcomputer 10 judges that the paper 5 is fed and moves a carriage 3 into a printing region. When the photosensor 1 passes the right end of the paper 5 shown in a drawing to become a state receiving the reflected light from a reflecting plate 4, the output of the amplifier becomes a 'Low' level in the same way as such a case that no paper 5 is present. At this point of time, the microcomputer 10 calculates the width of the paper 5.

Title: Distance measuring apparatus
Inventor: OISHI TADAHISA
IPC: G01S17/36
Filed: 1992-04-24
Abstract: PURPOSE:To enhance the resolution of a distance by a method wherein the optical signal of an n-order harmonic component [where (n) represents a positive integer] at a modulation frequency is used for a measurement. CONSTITUTION:A beam of light radiated from a light source 1 is input to a Mach- Zehnder type light-waveguide intensity modulator 2. A signal at a frequency of (f) from a signal generator 4 and a bias voltage from a DC bias power supply 5 are supplied to a coupling circuit 3. The modulator 2 modulates the beam of light by means of the signal at the frequency of (f) supplied from the circuit 3; it radiates a beam of light, for distance measurement use, which is provided with a component at a frequency of 4f. The beam of signal light is reflected by a reflector (a target object) 7; it is photodetected by means of a photodetector 8 and converted photoelectrically. Output signals from the detector 8 and a local oscillator 9 are mixed by means of a frequency mixer 10. A signal (a distance measuring signal) at a frequency of DELTAf which is provided with information on the phase of a distance measurement is output to a phase meter 11. The phase meter 11 finds the-phase difference between the distance measuring signal and a reference signal (at a frequency of DELTAf) which is supplied from a frequency mixer 13 for reference use. Thereby, a distance up to the target object can be found.

Title: Temperature controller
Inventor: HORII HIROSHI
IPC: H05B1/02
Filed: 1978-10-25
Abstract: PURPOSE: To make definite full-wave control possible even by using an inductive alternating-current dynamic power control element, by connecting a circuit, which delays a phase by a time equivalent to the arc-extinguishing angle of a current through the power control element, to the input side of a zero pulse generating circuit.  
     CONSTITUTION: A temperature control circuit for an electric blanket, etc., has additional circuit 75 (including resistance 76 and capacitor C77) which delays a phase by delay angle (θ) (arc-extinguishing angle of SCR47) determined by ratio R/L of inductance L to resistance value R of remote control relay 69 as a load, and consequently an input voltage to sixteen pins of control circuit 41 (including a zero pulse generating circuit) is delayed by angle of (θ). Therefore, a current flowing through secondary winding 692 of transformer relay 69 is lagging a power waveform by angle (θ) to cause unstable ON-OFF operation of its contact 70 in general and normal operation can not be expected, but since SCR47 is triggered through circuit 41 as mentioned above while a phase generated its trigger pulse is delayed by (θ), definite triggering is possible over the whole wave, so that inductive relay 69 will operate smoothly.
