Title: Measuring and evaluating method for short optical pulse
Inventor: NAGANUMA KAZUNORI
IPC: G01J1/00
Filed: 1986-09-08
Abstract: PURPOSE:To measure the level waveform and phase of an optical pulse to be measured by a small-sized, inexpensive device with high accuracy by measuring the relative waveform of a secondary higher harmonic light electric field. CONSTITUTION:A sampling interval, the time constant of an integral amplifier 10, etc., are set in desired relation. Then while a moving table 4 is moved at a constant moving speed, a waveform storage device 17 measures and records the output of the amplifier 16 and the output of the integral amplifier 10 passed through crystal 7 with secondary higher harmonic light generating ability. A computer 18 reads variations of the stored outputs of the amplifiers 16 and 10 and refers to the latter to correct the distortion of the former due to an irregularity in the moving speed of the moving table 4. Then a Fourier analysis of the correlation data is taken to find the level waveform of a pulse from a specific expression regarding a spectrum nearby a zero frequency among obtained spectra. Further, a frequency component of frequency almost twice the interference fringe frequency of a basic wave based upon the center wavelength of the pulse and the moving speed of the moving table 4 is extracted to find the phase of the pulse from the value raising it to the (1/2)th power and level waveform by repetitive calculation.

Title: Liquid crystal display keyboard
Inventor: ARAKAWA KAZUHIRO
IPC: G11B20/10
Filed: 1982-12-03
Abstract: PURPOSE:To prevent a disconnection fault of a transparent electrode by having a multi-layer structure for an upper transparent conduction film to disperse the contact pressure to a lower transparent electrode. CONSTITUTION:A film 8 made of a transparent elastic material is adhered on the upper surface of an upper transparent conduction film 6, and a transparent film 9 is adhered on the film 8 to obtain a 3-layer structure. Owing to this structure, the curvature is reduced at the side of the film 6 which is pushed by a pen P. At the same time, the contact area is increased to a lower transparent electrode 4. Thus the force is dispersed to reduce the curvature of the electrode 4. In case the characters, etc. are written by a pen P to recognize a pattern, a waving phenomenon due to the sliding of the pen P is absorbed by films 9 and 8. This eliminates the waving phenomenon of the electrode 4 and prevents the disconnection of the electrode 4.

Title: Metal halide lamp
Inventor: INOUE AKIHIRO
IPC: H01J61/12
Filed: 1982-12-03
Abstract: PURPOSE:To improve the starting performance and the luminous efficiency of a metal halide lamp by charging the emission tube with a starting rare gas, mercury, luminous metal and radioactive-matter-dispersed ceramic body, and substituting luminous metal for impurity contained in the ceramic body. CONSTITUTION:H-type zeolite produced by treating natural zeolite is immersed in the vapor of scandium iodide to be charged in an emission tube 2 so as to substitute Sc ion for remaining Na ion. Next, it is immersed in hydrochloric acid solution of <147>Pm, which is a radioactive matter, to catch <147>Pm atoms among zeolite particles thereby obtaining a zeolite body in which the radioactive matter is dispersed. After that, the thus obtained zeolite body, mercury, argon gas, the iodides of luminous scandium metal and sodium are charged in the emission tube 2, thereby constituting a metal halide lamp 1. As a result, any reduction in the luminous efficiency of the lamp 1 is prevented by substituting the luminous metal for impurity Na, thereby enabling the starting performance of the lamp 1 to be improved.

Abstract: PURPOSE:To omit a residual toner receiving vessel for receiving a dropped residual toner by leaving a residual toner scraped with a cleaning blade under the care of a charge holding body by an action of a rotating roller provided on the upstream side of the cleaning blade, and collecting it automatically to a toner developing device. CONSTITUTION:When a cleaning blade 23 is rotated to a position of a full line from a dotted line due to the end of copying, etc. and is separated from a photosensitive drum 1, a part 25 of a residual toner 19 scraped and accumulated by the blade 23 becomes like a lump and slips down along the surface of the photosensitive drum 1, but it is received in the shape placed between the adjacent surface parts of the photosensitive drum 1 and a rotating roller 24, and does not leak to the upstream side since the rotating roller 24 is driven and rotated in the direction as indicated with an arrow. On the other hand, if a parting property elastic base material such as urethane rubber, etc. is used as the rotating roller 24, the dropped toner 25 does not adhere to the rotating roller 24 but is carried, and at this time point, the blade 23 is separated from the photosensitive drum 1, therefore, all residual toners 19, 25 reach a toner developing device 8.

Title: Line shift controlling system
Inventor: SHIMOJI HIROSHI
IPC: G06F3/14
Filed: 1981-12-25
Abstract: PURPOSE:To save print paper, by displaying overlap-printed data to a character display and at the same time printing said data to a hard copy device. CONSTITUTION:A data containing a line shift control character which is used for printing to a line printer is delivered to a character display 5 and at the head of the data equivalent to one line by a central processor 1 and via a channel device 3 and a communication controller 4. The above-mentioned data is transferred and stored successively and with each line into a buffer B1. In this case, the line shift controlling character is detected at a line shift control character detecting part 7. Then a line shift control character deciding part 6 decides whether the line shift character requires the print of each line, the output of idle lines, the page shift, i.e., the line feed or the character requires the overlap-print with no line shift. If the line feed is required, the first data stored in the buffer B1 is transferred to a buffer B2.

Abstract: PURPOSE:To easily judge whether or not the message presently in display is the one succeeding to a next page by providing plural code detectors, an FF and the like, and black-white-inverting the final character at the displaying part, in a receiver such as a pocket beeper. CONSTITUTION:Code detectors 5 and 6 execute the code detection of the character data at a 6th character storing area of a shift register 2. At this time, a detector 5, when the character data are an STX code to show the start of the message, outputs a starting detecting signal, and a detector 6, when the character data are the ETX code to show the end of the message, outputs the completing detecting signal to an FF7. The FF7 is set or reset by the starting detecting signal and a completing detecting signal, and when the output signal of the FF7 is a prescribed value, the displaying switching signal is supplied to a 4th character displaying part of a displaying part 3 and the displaying character is black-white-displayed. When the ETX code is detected by the detector 6, the FF7 is reset, the black-white-inversion is not executed, and it can be judged that there is no message following the message presently in display.
