Title: Display tube for light source
Inventor: YURA SHINSUKE
IPC: H01J31/15
Filed: 1991-07-31
Abstract: PURPOSE:To provide the fine and accurate continuous image plane by providing a panel having a curved chamfered part, and forming light emitting points at one line or more, which are positioned with a dislocated pitch, to make a side surface look to emit the light. CONSTITUTION:A chamfered part 14 is provided in the periphery of a front surface panel 2, and position of the most outside light emitting point 15 at one line or more provided in the back surface of the chamfered part 14 is dislocated from the image element pitch. The light, which is emitted from the light emitting point 15 and travels to the front of a display tube, is bended in front of a side plate 4. Another one light emitting point 16 is formed between the light emitting point 15, which is positioned most close to the side plate 4, and the side plate 4. Since the light, which is emitted from the light emitting point 16 to the direction of the front surface, among the light emitted from this light emitting point 16 passes through the inclined surface of the chamfered part 14, it is bended not to travel forward. The light emitted diagonally front the light emitting point 16 is bended at the chamfered part 14, and travels forward. From a view of the front, the light emitting point 16 looks to be positioned in front of the side surface 4, and the light can be emitted from the side plate 4, and image element pitch which is twice or less the thickness of the side plate 4 is enabled.

Title: Mass spectrometer
Inventor: INATSUGI NORITO
IPC: H01J49/20
Filed: 1986-09-09
Abstract: PURPOSE:To obtain high resolution, by winding an auxiliary coil around a core while separately winding a main coil for magnetic field formation around the core and besides forming a switching circuit in which the auxiliary coil is shorted and opened in accord with measurement modes. CONSTITUTION:While a main coil 6 for magnetic field formation is wound around a core 4, an auxiliary coil 8 for removing hams and ripples and the like is wound around the core 4 separately from the main coil 6. In a switching circuit 10 in which the auxiliary coil 8 is shorted and opened in accord with measurement modes, its common contact 10a and one of its independent contacts 10b are connected with the auxiliary coil 8 and the other independent contact 10c is earthed. In case of a low-speed scanning mode, the common contact 10a of the circuit 10 is connected with the independent contact 10b so that the auxiliary coil 8 is shorted. Then, power of the hams and ripples superposed on an excitation current supplied to the main coil 6 from a power source circuit 12 is consumed in the auxiliary coil 8 by electromagnetic induction because of their high frequencies, so that fluctuation of magnetic field intensity can be suppressed. Therefore, high resolution can be obtained.

Abstract: PURPOSE:To set a squelch level simply with high accuracy by providing a means displaying a squelch level in relation to a reception signal level and a means comparing the reception signal level and the squelch level and muting the output in response to the result of comparison. CONSTITUTION:In setting a squelch level, the display location of a display element 16b is controlled by an up-pulse, down-pulse of a rotary encoder 17 while observing the lighting state of the display elements 16a, 16b of a display device 16, the level is set to a desired level. A comparator circuit 20 compares the reception signal level with the squelch level. Then the comparator circuit 20 controls the switching of a switch 7 in response to the result of comparison. For example, the comparison output of the comparator 20 opens the switch 7 to cut off a signal path from the detection circuit 6 to a low frequency amplifier circuit 8 when the reception signal level, that is, the output level of a shift register 13 is lower than the squelch level, that is, the output level of the shift register 18. That is, the reception output is muted.

Title: Drawing method for wire rod
Inventor: NAGAI HIROSHI
IPC: B21C1/00
Filed: 1986-09-10
Abstract: PURPOSE:To improve the service life of a hole die and the work quality even if a surface preparation stage for lubrication is eliminated by combining a roller die drawing and a hole die drawing including lubricant applying roller. CONSTITUTION:In one pass drawing, a hot wire rod is drawn by a roller die after descaling and then is made to be a product by hole die drawing. In roller die drawing, a lubricant is stuck to the entire wire rod surface because the lubricant application to an entire periphery is concurrently performed at the drawing. Further, in the hole die drawing, a lubricant 6 is stuck to only roller contacting parts when a wire rod 1 passes through a couple of flat rollers pulled to each other by a spring 3. As the result, the drawing of the lubricant 6 in the hole die drawing is improved and seizure is prevented. Therefore, the quality problems such as a condition of a wire rod surface and a dimensional accuracy are solved because a service life of a hole die is improved to the extent as long as that by a surface preparation for lubrication.

Filed: 1991-08-26
Abstract: PURPOSE:To improve image processing speed by simultaneously reading data for plural lines stored in an image memory at an image processor and simultaneously storing the data in a line memory. CONSTITUTION:A source image memory 1 stores the data of source images obtained by an image reader or the like. Concerning the data of source images stored in the source image memory 1, an access means 4 generates addresses for reading the data for plural lines.
