Title: Terahertz wave generator
Inventor: TAKAHASHI HIRONORI
IPC: H01S1/02
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To easily switch a frequency spectrum. SOLUTION: The terahertz wave generator uses an optical switch element 1 provided with an optical switch array composed of plural optical switches 10a-10f to supply different delay time to optical pulses made incident on the respective optical switches. By the constitution capable of switching the value or polarity of a voltage applied to the optical switches 10a-10f by a voltage controller 2, the terahertz wave generator capable of instantaneously switching the frequency spectrum of terahertz waves to be obtained is realized. Such a terahertz wave generator can be applied to various devices such as a terahertz wave spectroscope unit capable of efficiently performing measurement for instance.

Title: Ultraviolet ray irradiator
Inventor: ITO NAMIO
IPC: C08J7/00
Filed: 1985-09-26
Abstract: PURPOSE:To prevent the excessive cooling of a lamp with a ventilating means by providing a quartz cover surrounding the lamp in the titled UV ray irradiator utilized for the curing of printing ink, etc. CONSTITUTION:When a lamp 10 is turned on, a rotary vane 70 is simultaneously driven and the air contg. ozone on the inside of a lamp house 40 which has been warmed up by the lamp 10 is discharged from a vent 50. Besides, the external air is sucked from an air suction port 90 provided between a reflecting plate 20 and a filter 80 and the inside of the lamp house is cooled. Since the lamp 10 is surrounded with a quartz cover 100, the lamp is not brought into direct contact with the sucked external air, hence the temp. of the lamp tube is elevated, a thermal equilibrium is maintained at a temp. higher than that of the conventional lamp and the UV ray efficiency of the lamp is improved.

CONSTITUTION:A diamond tip 1 is heated in a no-oxygen atmosphere and its surface is graphitized as far as less than 10mu in thickness, thus a graphitized layer 2 is formed. A metal plating layer 3 consisting of a metal element or an alloy selected out of nickel, cobalt, chromium, titanium, etc., is applied to a part being brazed to a partial surface of this graphitized layer 2. Thickness totaling both these layers 2, 3 should be set down to a range of 15-25mu, and they are brazed to a base metal 4 with silver or gold solder 5. With this constitution, the tip can be roughened for a good conductor and thereby a rigid metal plating layer is formable on the surface, thus the tip can be firmly unified to the base metal.

Consequently, the structure of the Si3N4 film of the surface protective film 11 which is in contact with metal wirings of source and drain electrodes directly is compact and does not include impurities so that it is hard of allowing water to penetrate. Accordingly, hillocks are not produced on the metal wirings of source and drain electrodes and corrosion of the metal wirings of source and drain electrodes due to enchroachment of water into a semiconductor device can be prevented. Also, as alkali ions such as sodium and potassium are hard to penetrate the Si3N4 film, they do not reach a gate oxide film 4.

Abstract: PURPOSE:To obtain a wide dynamic range while holding an A/D converting device at low cost by limiting an analog dither signal so that the addition value of an analog information signal and the analog dither signal is not larger than the maximum permissible input value of an A/D converter. CONSTITUTION:When the input analog information signal is at low level, the output of a digital dither generator 3a is converted by a D/A converter 36 into the analog dither signal as it is. when the level of the input analog information signal is between VR1 and VR2, only the 1st comparator C1 generates a high level output to turn off only the switch S1 of the signal line of the MOSB and hold remaining switches S2-S12 on. Therefore, the 11-bit dither signal is D/A-converted and supplied to an adder 2 and an A/D converter 12. when the input analog information signal level V8 is higher than a reference voltage VR12, all comparators C1-C12 generate high-level outputs, so all switches 51-512 are turned off and the supply of the dither signal is interrupted.

Abstract: PURPOSE:To properly drive a display element having high temperature dependency by changing the pulse width of a display driving signal to compensate temperature change. CONSTITUTION:The screen temperature of a ferro-electric liquid crystal display 14 is detected and the pulse width of a write signal is changed in accordance with the temperature to control driving. Namely, the pulse width or voltage of driving signals for both a scanning side driver and a signal side driver is varied in accordance with the temperature of the display 14. Since the pulse width of both the drivers is changed, the pulse width of the driving signals can be rapidly changed as compared to a case changing only the pulse width of the scanning side driver or the signal side driver, and since the voltage of both the driving signals is changed, the change can be rapidly executed and a large voltage difference due to the change of density can be validated, so that control can be efficiently executed in accordance with the temperature of the display.

Filed: 1987-08-25
Abstract: PURPOSE:To accurately form the notch of a covered wire and to prevent a cutting edge from damaging by interposing an elastic member between a movable member and a guide member. CONSTITUTION:When a cylinder mounted on the back of a panel, not shown, is operated to intrude a chain 46, a connecting tool 45 is pulled by the chain 46 to advance a movable member 42, and a guide member 44 is pressed forward through an elastic member 49 in this manner. When the end 442 of the member 44 is in contact with a coated wire C positioned by a chuck mechanism, not shown, the member 44 does not advance any further, the member 42 then advances while pressing in compression an elastic member 49, the cutting edge 431 of a cutter 43 protrudes from the member 44, and is introduced to a notch forming position set at the wire C. Thus, a seam C1 of predetermined width extending toward an axial center is effectively formed on the coating C1 to prevent the edge 431 from damaging.

Filed: 1983-11-11
Abstract: PURPOSE:To simplify the editing operation for tabulation by designating a cell to copy it with enlargement or reduction and providing a cell memory which stores data on the cell position, etc. to designate an optional displayed cell. CONSTITUTION:A tabulation editing controller 8 supplies an instruction given from a keyboard 1 to an instruction analysis part 21 and transfers the instruction to the next cursor position detecting part 22 after analysis. The cursor position information supplied from the keyboard 1 is given to the part 22, and the cursor position coordinates are detected. Then the instruction analysis information and the cursor position coordinates are transferred to a cell and abutting side specifying part 23. The part 23 reads out the cell data 26 out of a memory to compare it with the cursor coordinates and then transfers the row or column editing designation information and an input instruction to a cell data update part 24. Thus the cell data stored in the memory is updated. A display part 25 reads out the updated data 26 and delivers it to a refresh memory RFM for display at a CRT.
