Title: Character drawing device
Inventor: TAKAGISHI KAZUFUMI
IPC: G06T11/20
Filed: 1989-06-12
Abstract: PURPOSE:To improve the quality of half-sized (or en) characters by calculating a reduction rate according to the letter area width of each character stored in outline font data and drawing the characters when the en characters are specified. CONSTITUTION:Letter area width data on each character is added to the outline font data and the reduction rate of each en character is found from the data to draw the character. Namely, the outline font data stored on an outline font memory 4 is contour line data and letter area width of each character and a drawing means 5 calculates the reduction rate from the letter area width on the outline font memory 4 at the time of en character drawing and outputs it to a display device 6 or output device 7. Consequently, too much character spacing and too thin lines are improved at the time of en character drawing to improve the quality.

Inventor: YOSHIHARA KOUICHI
IPC: C22B26/20
Filed: 1977-12-07
Abstract: PURPOSE: To recover Sr in a high yield by adding a surfactant to a liquid contg. coprecipitated Sr and Fe(OH) 3  to render the precipitates hydrophobic and introducing fine bubbles into the liquid to stick them to the precipitates, which are then allowed to rise to the liquid surface.  
     CONSTITUTION: To an acidic liquid contg. severalWseveral tens mg/l of dissolved Sr is added a soln. of ferric ions such as FeCl 3  or Fe 2 (SO 4 ) 3  in an amt. of 2W5 times as much the ions (as Fe) as the Sr content. The liquid is then adjusted to pH 10W13 with an alkali such as NaOH to precipitate Fe(OH) 3 . At this time, the Sr in the liquid is coprecipitated with the Fe(OH) 3  or adsorbed on the Fe(OH) 3  surface. Next, to the liquid are added anionic surfactants as principal and auxiliary capturing agents, e.g. 50W100 mg/l of sodium oleate and 20 mg/l of sodium dodecylbenzenesulfonate, followed by stirring. Fine bubbles are introduced into the liquid, and the precipitates rendered hydrophobic by adhesion of the surfactants are sticked to the bubbles, allowed to rise, separated, and recovered.

Filed: 1992-05-13
Abstract: PURPOSE:To enhance accuracy of R wave synchronous multi-gate image in electrocardiogram by eliminating image data for arrhythmogenic heart beat and arbitrarily set subsequent heart beat from multi-gate image forming data. CONSTITUTION:An arrhythmia counter 15b is set at 0 and gamma ray 35 is taken from a specimen into a collecting circuit 36 and then stored, as an image data 37, into a buffer memory 11. At the same time, an electrocardiogram 32 is taken from an electrocardiograph 33 into an R-R circuit 14 where an R-R interval 34 is detected at every hear beat and delivered to a CPU 15. The CPU 15 makes a decision whether the R-R interval comes within a set time range. If it comes within the set time range, the CPU 15 decides that the hear beat is normal and a multi-gate converting circuit 12 converts the image data 37 into a multi-gate image 38 which is then stored in a memory 13. Upon decision of arrhythmia, number of hear beat to be removed is set in the counter 15b and image data for arrhythmogenic hear beat and subsequent heart beat is removed thus enhancing accuracy of multi-gate image.

Abstract: PURPOSE:To increase the number of recording bits and to improve the recording density by diminishing the light intensity in the vicinity of a center of a cross section of an outgoing beam when reflected light from a converging point as a microspot formed from the outgoing light from a laser light source is led to a photodetector. CONSTITUTION:When the outgoing light from a semiconductor laser 1 is condensed by a condenser lens 4 to be converged on a recording medium 5, a part of the outgoing light is reflected by a beam splitter 2 located usually between the laser 1 and a lens 3, and the intensity of the beam is detected by a regenerative signal detector 6. In this constitution, a light intensity distribution modulator 3 is newly inserted between the splitter 2 and the lens 4, so as to diminish the light in the vicinity of the center of a circular or ellipsoidal beam cross section. That is, the modulator 3 is specified as a transmission type, and in the vicinity of its middle part, an aluminum metal 62 finished with black dye for lowering the reflection intensity is provided to reduce the light intensity in the center part of the beam. By this method, the effect of the reflected light from the medium 5 is reduced to promote the recording density.

Filed: 1982-08-27
Abstract: PURPOSE:To improve the track following stability and to eliminate the dependence on a cylinder for a position modulator, by equalizing position sensitivity on both inner and outer circumferences of the cylinder. CONSTITUTION:A compensator 9 is provided to a position signal demodulator 8, and a servo signal 7 is read out of a servo surface 5 of a disk 4 by a servo head 6. A position signal is demodulated by the demodulator 8, and the compensator 9 works to obtain the fixed position sensitivity. Then the compensated position signal is fed to a detector 10 to obtain a speed signal. In accordance with this speed signal, a driving mechanism part 12 is controlled by a control circuit 11 to position the head 6. An analog switch 14 is switched by the compensator 9 in response to a cylinder address extracted from a register 13 which varies the shift of the head 6. Thus the gain of an operational amplifier 15 is increased or decreased to compensate a position signal 16 having different position sensitivities between inner and outer cylinders. Then a position signal 17 having constant position sensitivity is obtained.

Abstract: PURPOSE:To obtain a retrievable expressions by holding the relative information with relation secured with each item and setting a key word for each item to show only the local features. CONSTITUTION:A set A is defined as all sets of IDs (step 1), and all candidates of a certain item a are extracted to produce a set B of a group of IDs (step 2). Then the crossing is calculated between sets A and B as a set B, and this set B is used as a candidate of the item a (step 3). The set B is selected rigidly and the IDs of this set are defined as a set A (step 4). If the number of elements of the set A is equal to one, the procedure ends. If not, the procedure is set again in the step 2 (step 5). As such a retrieving process is carried out based on the items not on the documents, all documents stored in a data base are retrieved at a time. Therefore the relative information can be successively retrieved.

Abstract: PURPOSE:To enable obtaining high economy, the high discharge stability and the rapid rise characteristic at the time of resuming operation by using an N2 gas for the gas filled after the termination of the operation and the gas used in a refreshment process. CONSTITUTION:After the operation of an alternating current discharge excitation type gas laser device is stopped, at least an N2 gas of a laser medium gas is encapsulated at the atmospheric or higher pressure in a laser medium gas circulating system and the device is left as it is. When the operation is resumed, at first, the laser medium gas of the N2 gas which has higher partial pressure ratio in the gas laser device is exhausted by drawing a vacuum by a vacuum pump. If the pressure is not reduced under a required pressure for a definite exhaust operation time, the N2 gas is filled again, then exhausted by drawing a vacuum and the inside of the device is refreshed. This enables obtaining high economy, the high discharge stability and the rapid rise characteristic at the time of resuming the operation.

Filed: 1992-05-14
Abstract: PURPOSE:To convert dynamic display data into static display data and to prevent a noise due to a dynamic display by inserting a monostable multivibrator between a micro computer and a current driver for a light emitting diode. CONSTITUTION:By an LCD 2, a dynamic display is performed with the dynamic display data from the displaying output terminal of the micro computer MPU 1. Further, the display data is outputted to a data line to the MPU 1 similarly and since the data is inputted to the able multi-vibrators 3-1 to 3-n, the outputs of the vibrators maintain an H-level by the time constant of a resistor and a capacitor provided in the monostable multi-vibrator and since operation that the time constant is updated by the rise edge of a next pulse before a time is ended is repeated, the output is converted to the static display information. Thus, by the current drivers 4-1 to 4-n, the current continues to flow through the light emitting diodes 6-1 to 6-n while the static display continues.
