Patent number: 7090388Abstract: A light source device which is uniform in the intensity of distribution of an emitted light and high in the optical utilization efficiency, a display device which is high in recognability and is energy-saving, and an information terminal are provided. A reflecting portion is formed on a surface opposed to an emitting surface of a linear light guide. The reflecting portion is periodically formed with a total reflecting surface guiding a light incident on a linear light guide from a point light source, a light extracting surface allowing the light to reflect in such a way as to emit the light guiding the linear light guide from the emitting surface, and a re-incidence plane which takes the light transmitted but not reflected on the light extracting surface into the linear light guide again. By changing the size of the light extracting surface and the re-incidence plane, the intensity of distribution of the emitting light from the linear light guide can be made uniform.Type: GrantFiled: May 19, 2004Date of Patent: August 15, 2006Assignee: NEC CorporationInventors: Yoshie Yagi, Masao Imai, Goro Saito, Koji Mimura

Patent number: 4845642Abstract: A display device for complex transmission reflection characteristics processes the amplitude and phase of input complex number data, and displays the processed amplitude and phase. A number of types of coordinate chart image data are stored in a memory and displayed, and chart image data selection circuitry selectively reads one or more types of the coordinate chart image data from the coordinate chart data memory, in response to an input display command signal. A gain controller/phase shifter gain-controls the amplitude and phase of the input complex number data, to correspond to the selected image coordinate data, and signal-processing circuitry superposes the one or more types of selected chart image data and complex number data processed by the gain controller/phase shifter. The input complex number data is then displayed in a desired one or more types of coordinate systems.Type: GrantFiled: December 1, 1986Date of Patent: July 4, 1989Assignee: Anritsu CorporationInventors: Hiroshi Itaya, Goro Saito

Patent number: 4812738Abstract: Measuring signals whose frequencies stepwise vary with time are fed to a test port of a reflection signal separator through an input port. A through transmission path and short- and open-circuiting elements are selectively connected to the test port. The reflection signal separator has an output port to allow a reflection signal from the test port and transmission signal passed via the through transmission path to be stored in first to third memory circuits through first and second heterodyne receivers equipped with a level correction function. A calculation circuit allows output signals of the first and second heterodyne receivers when an object to be measured is connected to the test port to be calibrated with the use of memory contents of first, second and third memory means so that the output signals are displayed on a display device.Type: GrantFiled: December 1, 1986Date of Patent: March 14, 1989Assignee: Anritsu CorporationInventors: Hiroshi Itaya, Goro Saito

Patent number: 4802106Abstract: A signal analyzing means performs frequency sweep for input signals to be measured, and outputs vector data corresponding to sampling frequencies. The analyzing means supplies pulses to a sweep marker generating means at timings for causing the signal analyzing means to supply the vector data corresponding to the sampling frequencies to the display means. Whenever the sweep marker generating means receives a pulse from the signal analyzing means, it outputs address data for extending a sweep marker. The display means includes a CRT and displays a designated polar coordinate image on the CRT screen. The display means translates the vector data to address data of a position suitable for the polar coordinate image. The address data and sweep marker address data are superposed on polar coordinate data displayed on the CRT screen. The vector data and the sweep marker are simultaneously displayed on the CRT screen.Type: GrantFiled: April 16, 1986Date of Patent: January 31, 1989Assignee: Anritsu CorporationInventors: Goro Saito, Hiroshi Itaya

Patent number: 4780712Abstract: A signal analyzer outputs polar coordinate data to be displayed on an image display unit employing a raster scan scheme. First and second image memories having memory formats corresponding to the screen of the image display unit are provided. A memory switching circuit switches the first and second image memories at each measurement scan so that either one of the first and second memories is set at a write side and a remaining one is set at a deletion side. The polar coordinate data is sequentially written in one of the first and second image memories, data of a previous scan written in the other of the memories is sequentially deleted, and data of both memories are read out simultaneously, so that the polar coordinate data is displayed on the image display unit of the raster scan scheme without discontinuity and in a real time manner.Type: GrantFiled: December 1, 1986Date of Patent: October 25, 1988Assignee: Anritsu CorporationInventors: Hiroshi Itaya, Goro Saito

Patent number: 4710702Abstract: A signal-measuring apparatus for measuring a level of a signal to be measured includes a reference signal oscillator, a variable local signal oscillator, a heterodyne type mixer, a bandpass filter and automatic detuning correction means. In the automatic detuning correction means, there are provided a peak value memory, a tracking circuit and a detuning-correction calculating circuit. When a filter output is obtained by passing the reference signal through the bandpass filter, a peak value is acquired by varying the oscillator frequency of the local signal. This peak value is stored in the peak value memory. Then, the signal to be measured is supplied to the bandpass filter to acquire another filter output. This filter output is calculated in the detuning correction calculating circuit based upon the above-described peak value as a reference value so as to correct the error caused by the filter detuning.Type: GrantFiled: December 10, 1986Date of Patent: December 1, 1987Assignee: Anritsu CorporationInventors: Hiroshi Itaya, Goro Saito
