Title: Cathode-ray tube
Inventor: MORIWAKI MASARU
IPC: H01J29/50
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To prevent the inside region containing a large circular coining from projecting and deforming in a heat treatment to remain reliability of a cut-off voltage, by sequentially increasing thickness a of grid electrode from the circumference of an electron beam passing hole toward the outer diameter direction. SOLUTION: This tube is constituted so that thickness gradually increased from a small circular coining region 11 to a bending part 13. A part adjacent to the bending part 13 of a large circular coining region 12 has a maximum thickness to, and it is almost equal to the thickness to the support member of a grid voltage with other member. When the large circular coining region 12 is designed to have a uniform thickness (t) and is actually press-molded, for example, a part adjacent to the small circular coining region 11 is formed to be thicker than the part adjacent to the bending part 13. Heat treatment of this releases a machining strain from a base part of the large circular coining 12 and causes projecting or recessed deformations. Therefore, by making the part adjacent to the bending part 13 thicker than the part adjacent to the small circular coining region 11, the deformation is prevented.

Title: Liquid crystal display device with input function
Inventor: FUKUNAGA YOKO
IPC: G09F9/00
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To obtain excellent position detection sensitivity and precision irrelevantly to the display state of liquid crystal by making only light in the invisible range selectively reach an optical detecting means by a filter. SOLUTION: A light energy distribution reflected by a liquid crystal cell is limited to the visible area and cholesteric liquid crystal itself is transparent in the near infrared-ray range, so near infrared light from a light input pen 30 reaches a common electrode 16. The common electrode 16 is formed of the ITO and the transmissivity to the near infrared-ray range is high, so the near infrared light from the light input pen 30 reaches the filter 15. The near infrared light transmitted through the filter 15 reaches an I layer 14 in the PIN structure of the PSD to generate a couple of plus and minus photocarriers. Visible light transmitted through the liquid crystal cell is absorbed by the filter 15 and does not reach a photodiode 14 irrelevantly to the display state of the liquid crystal. Therefore, the photodiode 14 selects and receives only the infrared light from the input pen 30.

Title: Method and apparatus for voltage-frequency conversion
Inventor: HAAGEN HARUTOUITSUHI
IPC: H03K7/06
Filed: 1990-03-14
Abstract: PURPOSE: To provide a speedy high-accuracy voltage/frequency converter having a long frequency span by generating a regulated voltage from the sum of a differential voltage and an upward shifted input voltage and applying this regulated voltage to respective integrators to be used. CONSTITUTION: When an arbitrary input voltage UE is applied to the 1st input terminal of an adder S, this voltage is shifted upward and applied to the input terminal of an integrator J. This input voltage is first integrated and applied to the input terminal of a comparator VG as an integrated voltage UI. At the same time, a reference voltage UA to be compared with the integrated voltage UI is applied to the comparator VG. Thus, a differential voltage UD corresponding to the difference between the reference voltage UA and the integrated voltage UI is generated at the output terminal of the comparator VG. A regulator RG is constituted as a high-speed integrator. The more the control deviation UD is enlarged, the more an I regulator speedily integrates the voltage in the correspondent direction.  A voltage controlled oscillator VCO generates an output signal UV in the form of a pulse stop signal of which the pulse stream frequency is proportional to the output of the regulator RG.
