Title: Crt driving circuit
Inventor: TSUKAGOSHI KAZUO
IPC: H04N3/20
Filed: 1985-12-05
Abstract: PURPOSE:To prevent destruction of the phosphor of a CRT by discriminating that horizontal deflection output is stopped by a pulse from a secondary winding for pulse detection and cutting beam current of the CRT by controlling a video output circuit. CONSTITUTION:A negative polarity pulse 22 is outputted from a winding 13 for pulse detection, and voltage 23 is formed from the negative polarity pulse by a diode 14 and a smoothing capacitor 15, and inputted to the base of a transistor TR 16. Reference voltage is given to the base of an output side transistor TR 17 of the TR 16 by a series circuit of a power source 12, a resistance 20 and a Zener diode 21. When voltage 23 becomes lower than voltage of the diode 20, the TR 16 becomes on-state, and current flows in a resistance 19 and collector voltage is outputted. The collector voltage is supplied to a video output circuit 7 to stop operation and cut off beam current of a CRT 3.

Inventor: TSURU TERUHISA
IPC: H01Q1/36
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To ensure a desired resonance frequency. SOLUTION: The chip antenna 10 is formed by providing a conductor 12 made of copper or copper alloy and wound in spiral in the lengthwise direction of a rectangular parallelepiped base 11 in the inside of the base 11 made of a dielectric material whose major component is barium oxide, aluminum oxide or a silica. One end of the conductor 12 is led to a surface of the base 11 to form a feeding end 17 formed on the surface of the base 11 to apply a voltage to the conductor 12, and the other end forms a freely end 18 in the inside of the base 11. In this case, a resonance frequency f0 of the chip antenna 10 and an inductive component L of the conductor 12 satisfy a relation of ln(L)=A0+A 1×ln(f0), where ln is natural logarithm, and A0, A1 are constants.  Then a cutting line 19 is formed around the free end 18 of the conductor 12 by trimming the conductor 12 with a laser together with the base 11 and the resonance frequency f0 of the chip antenna 10 is adjusted by adjusting the inducitive component L of the conductor 12.

Title: Digital/analog converter
Inventor: TSUJI KAZUHIRO
IPC: H03M1/08
Filed: 1990-10-16
Abstract: PURPOSE:To form a highly accurate D/A converter by switching a circuit component selected by an input code hourly so as to average the dispersion hourly even when circuit components have the dispersion in an array system D/A converter. CONSTITUTION:Selector switches SW1-SWn are controlled by a time variable decoder 1 so that the connecting position is made variable depending on a decoder switching timing even when the number of capacitors connected by an input code Din is the same. Consequently, the output is more or less fluctuated as sown in full lines in the decoder switching timing TSW even when the input code Din is the same depending on the dispersion in each capacitance of the capacitance array. However, the decoder switching timing is quickened with respect to the signal band to select the capacitor connected to a reference voltage Vr at random hourly, thereby averaging the output hourly through a low pass filter. Thus, an output voltage Vout is close to an ideal value (shown in broken lines) and a highly accurate result is obtained.

Title: Optical noise measuring instrument
Inventor: MACHIDA SUSUMU
IPC: G01J1/44
Filed: 1988-11-04
Abstract: PURPOSE:To simultaneously measure the shot noise level and the amplitude noise of light to be measured to absolutely evaluate the noise by dividing the light to be measured into two and detecting divided components independently of each other and delaying one output signal and synthesizing the difference or the sum again. CONSTITUTION:Incident light A0 to a beam splitter 2 and a fluctuation component C in a vacuum field of quantum mechanics which is made incident from another input terminal are divided into two, and fluctuation components of the detection current which passes a photodetector 4 and is delayed by a delay circuit 8 and the current which is only detected by a photodetector 5 are denoted as I1 and I2 respectively. When OMEGAintau=2Npi (N is a positive integer) is true where tauis the delay time and OMEGA is the frequency, the output of a differential amplifier 6 is I0in=I1-I2 and indicates the shot noise level by difference synthesis; and when OMEGAouttau=(2N+1)pi is true, the output is I0out=I1+I2 and indicates only the amplitude noise component of the incident light by sum synthesis. Consequently, an output current I0 is measured by a frequency select level meter 7 to precisely measure both of them.

Title: Recording and reproducing device for pcm signal
Inventor: NEMOTO SHOJI
IPC: G11B5/09
Filed: 1985-12-10
Abstract: PURPOSE:To attain the complete erasion of the index signal even in case the gap width of a head is smaller than the track width, by setting the driving speed of a magnetic tape at a level lower than the normal reproduction speed for erasion of the index signal. CONSTITUTION:The index erasion mode signal is obtained at an input terminal 57 for index erasion mode signal and a movable contact 56c of the 2nd switch circuit 56 is connected to a fixed contact 56a set at one side. As a result, the revolving speed signal of a capstan motor 52 which is supplied to a speed servo circuit 58 is trebled compared with the actual speed converted by a speed signal converting circuit 55. Thus the circuit 58 controls a capstan motor 52, etc. to set the tape speed at a 1/3 level and then set the speed signal supplied to the circuit 58 at a normal speed. The scan is carried out successively with overlap caused between tracks by half because the tape speed is slowed down to 1/3 and also the track width of a head is equal to about 3/4 normal track width. In such a scan mode the head locus is never set parallel with a recording track owing to the different tape speeds.
