Title: Method and device for correcting alignment tolerance for scanning head
Inventor: LEE HYUK-JAE
IPC: H04N1/04
Filed: 1998-07-14
Abstract: PROBLEM TO BE SOLVED: To acquire a normal printing state by performing correction while applying a set correction function to other pixels except for the start point and end point of pixels. SOLUTION: When the selection of an alignment tolerance correction mode is judged, a central processing unit(CPU) 13 drives a carriage return motor 4, moves a scanning head 2 to the left side and locates the scanning sensor of the scanning head 2 at a spot opposed to the pattern for correction of a correction plate 8. The CPU 13 operates the scanning sensor of the scanning head 2 and performs control so as to read the pattern for correction. The CPU 13 operates the alignment tolerance of pattern image data stored in a memory 11 for the unit of a pixel while controlling an arithmetic part 12, moves the final pixel just for an amount corresponding to the alignment tolerance with a 1st pixel as a reference and corrects the alignment tolerance. When the start point and end point of the pixel are completely corrected, linear correction is performed while applying a differentiation function to the other pixels except for the 1st and final pixels.

CONSTITUTION:For example, 180ml 0.02N hydrochloric acid is added to 208g (1mol) ethyl silicate and the mixture is vigorously stirred to hydrolyze. 73.2g fine powder silica (1.22mol) is added to the sol under stirring and 0.1N aq. ammonia is added dropwise thereto to adjust the pH to 4.0. The sol is then added into a PP vessel provided with figures and marks, etc., for scale and display at 2mm intervals and is geled. The wet gel is taken out of the vessel and is put into a drying vessel where the gel is dried for 7 days at 60 deg.C to prepare the dry gel. The dry gel is sintered up to 1,300 deg.C to form the quartz glass. The quartz glass provided with the figures and marks, etc., for the scale and display at 1mm intervals is thus prepd. The high-accuracy prototype for length which is usable even at a high temp. and is less deteriorated with lapse of time is thereby obtd.

Title: Quadrapole mass spectrometry device
Inventor: TERAKURA IKUTAKE
IPC: H01J49/42
Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To reduce the scanning time in a mass scanning condition. SOLUTION: A CPU 31 reads an adequate data from a memory 32, and gives it to an A/D converter 30. By the output voltage from the D/A converter 30, the values of the DC and the high-frequency voltage applied to the electrode of a quadrapole mass filter 25 are decided. The timing of the D/A converting operation is controlled by the CPU 31. The holding time of the applied voltage is decided beforehand according to the time necessary to pass an object ion through the electrode, and the CPU 31 controls the timing, by making the larger the mass of the ion, the longer the holding time. Consequently, the time necessary for one round scanning is made shorter.

IPC: H01Q19/12
Filed: 1986-08-28
Abstract: PURPOSE:To remarkably reduce the effect of a multi-path such as a side wall and to form an excellent communication channel by constituting the titled system by a reflecting mirror having a parabolic face, a 1st antenna placed nearly at the focus of the reflecting mirror, and a 2nd antenna placed at the Fresnel region of an antenna system comprising the reflecting mirror and the 1st antenna.

In such a case, the action of the parabolic mirror and the provision of the 2nd antennas 31, 32 located in the Fresnel region of the antenna system comprising the 1st antenna 4 and the parabolic mirror 2 cause no spread of radio wave. Thus, the path is limited to the path 81, multi-path hardly takes place and the interference due to multi-path is reduced remarkably.

Title: Heat developing device
Inventor: ISAKA KAZUO
IPC: G03D9/00
Filed: 1989-08-03
Abstract: PURPOSE:To perform heat development without causing a heat fog phenomenon by arranging heating electrodes of an energizing/heating means so that the distance between both electrodes partially differs resulting in non-parallel form. CONSTITUTION:The heating electrodes 2 are arranged so that their distance steadily widens, and therefore a change in the temperature of a point A on a photosensitive body 1 maintains the temperature for a while after it reaches a certain temperature. Consequently, heat development is performed at a prescribed temperature during a required period to obtain sufficient developing effects. The shape of the electrode 2 is preferably symmetric with respect to a central line between the facing electrodes 2, and they come to be uniformly or partially closer to each other. Consequently, heat development is carried out without causing a heat fog phenomenon.

IPC: G02F1/361
Filed: 1991-08-09
Abstract: PURPOSE:To obtain a nonlinear optical crystal which has an excellent nonlinear optical characteristic and is hard and large by subjecting specific O-nitroaniline- P-sodium sulfonate to a recrystallization treatment with ion exchange water and drying the filtrate under a reduced pressure after filtration. CONSTITUTION:The metal salt of the O-nitroaniline-P-sodium sulfonate expressed by formula I is subjected to the recrystallization treatment. In the formula II, X is any of Li, Na, K, Rb, and Cs. The benzene ring of the O-nitroaniline-P- sulfonate has a conjugated pi electron system and the amino group of an electron-donating group and the nitro group of an electron-accepting group are incorporated into this conjugated pi electron system. The O-nitroaniline-P- sulfonate, therefore, has a high nonlinear polarization rate in the molecule itself. Since the crystal structure of the O-nitroaniline-P-sulfonate crystallized by the effect of the polarity of the water at the time of the recrystallization treatment by the water is small in the degree of the crystal of the central symmetry, the high quadratic nonlinear optical characteristic is obtd.

Title: Frying pan and food fly-out preventing tool
Inventor: YAMAMOTO MASAHIKO
IPC: A47J37/10
Filed: 1995-08-07
Abstract: PROBLEM TO BE SOLVED: To provide a frying pan not heavier than required, capable of preventing food inside from flying out at the time of cooking fried food and not obstructing the use of a food turner. SOLUTION: At the time of holding a handle 15, moving this entire frying pan 10 forward (in direction A) and stopping it, the food X on the bottom surface 11 is moved into the direction of a front sidewall 13 by the force inertia. At this time, when a timing is chosen and the frying pan 60 is pulled to this side (in the direction B,) the food X is flown to a hand side along the curve (p) of the front side wall 13 and the food X is turned. At this time, since the height of the front sidewall 13 is made larger than a rear side wall 14, caring not to make the food X fly out from the side of the rear sidewall 14 is sufficient. Also since the front sidewall 13 is in a parabolic shape to which a turn (p) is attached, the food X hardly flies out from the frying pan 10.
