Title: Input limiter circuit
Inventor: KUWABARA TAKASHI
IPC: H03G11/00
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To set an allowable voltage with precision and also to enable fast response by providing an input means which apply an input voltage and an output of a differential voltage generation circuit, subtracting the differential voltage from the input voltage and controlling the voltage to be inputted to a signal processing circuit. SOLUTION: When the magnitude of an input voltage 1 is between a negative side limit voltage -Vm and a positive side limit voltage Vp, the outputs of ideal diode circuits 70 and 80 are zero and only the input voltage 1 is inputted to an operational amplifier 2. When the magnitude of the voltage 1 exceeds the voltage Vp, the voltage 1 and an inverted positive side limit voltage -Vp are added and an inverted voltage is outputted from the circuit 70. Therefore, a result obtained by adding the voltage 1 of the amplifier 2 and the output of the circuit 70 always becomes +Vp and, consequently, the input voltage of the amplifier 2 can be limited to the magnitude of the +Vp.

Title: One-component toner
Inventor: OCHIAI MASAHISA
IPC: G03G9/08
Filed: 1988-02-08
Abstract: PURPOSE:To maintain the secrecy of a document having image information and to prevent recopying thereof by incorporating a fluorescent dye which forms a color only under UV rays into the toner. CONSTITUTION:This toner contains a resin for fixing and the fluorescent dye which forms the color only with the UV rays. The toner contains further a charge control agent, white pigment and external additives at need. The toner is, therefore, colorless and white and is illegible under natural light and general illumination mainly consisting of a visible light region. In addition, the recopying of said toner is not possible. The visualization of the image is enabled by projecting the UV rays existing in the absorption wavelength region of the fluorescent dye. Namely, the fluorescent dye incorporated into the toner in the image receives the excitation by the UV rays and emits light at the wavelength intrinsic to the fluorescent dye, by which the image information is visualized and is made legible. The secrecy of the document is thereby preserved and the recopying is prevented.

Title: Disk record reproducer
Inventor: NAKANE HIROSHI
IPC: G11B21/10
Filed: 1983-02-21
Abstract: PURPOSE:To stop quickly the movement of a pickup when the track jump of the pickup is over by detecting that the pickup crosses a pit string in the direction opposite to the moving direction of the pickup owing to the track jump signal, then stopping the generation of the track jump signal. CONSTITUTION:A pickup 12 is shifted forward in accordance with the track jump signal, and a spot crosses a pit string. Thus the tracking error control signal is produced from a tracking error control signal generating circuit 13. Then a system controller 8 delivers a command to a track jump signal generating circuit 19 to invert the polarity of the track jump signal. The track jump signal is inverted to the negative polarity, and hereafter the forward shift of the pickup 12 is damped. When the spot crosses the pit string in the direction opposite to the first crossing direction, a reverse direction detecting circuit 23 delivers an output to the controller 18 to stop 19 the generation of the switch signal.

Title: Spectrum analyzer
Inventor: YOSHIDA TAKASHI
IPC: G01R23/173
Filed: 1991-02-21
Abstract: PURPOSE:To enable a non-periodical short input such as a burst wave to be also analyzed by a digital-type spectrum analyzer using a wide-band and high- resolution A/D converter and by step-sweeping a frequency of a local oscillation signal with a frequency width which is equal to approximately 1/2 or less of a sampling frequency of the A/D converter. CONSTITUTION:Sweeping of a local oscillation frequency is performed in steps with a specified width of 1/2 or less of a bandwidth of an A/D converter (sampling frequency, fAD). A real-time spectrum analysis is made to the input signal in a region within this bandwidth. When a band of the frequency which is to be subjected to spectrum analysis is within this bandwidth, it is not necessary to perform step sweeping of a local oscillator and sweeping may be performed only when this width is exceeded, thus achieving; a high-speed analysis. For example, when the frequency component from a point A to a point B is analyzed, an amount of t was required for analysis conventionally due to continuous sweeping. However. step sweeping may be performed only for two times and a high-speed analysis can be made, thus achieving an analysis even for an abrupt signal such as a burst wave.
