IPC: H04N1/60
Filed: 1991-11-11
Abstract: PURPOSE:To increase the speed by optionally changing the operation processing time while providing the color correction circuit of a correction signal D/A conversion part and an operation circuit part. CONSTITUTION:The color correction circuit is provided with an operation circuit part 3a calculating the RGB picture voltage value after the color correction of the analog value from an RGB correction voltage of the analog value, a correction signal D/A conversion part 4 converting the digital RGB correction value into an analog RGB correction voltage value 8, and an operation circuit part 3C having a multiplication circuit 1C multiplying the analog value and an adder circuit 2C adding the analog value. In this case, an RGB color correction coefficient 5 of a digital value is set to the color correction D/A conversion part 4 to be converted into the RGB color correction voltage value 8 of an analog value. In operation circuit parts 3a to 3c, the RGB picture voltage value 8 are taken as input, performing the analog color correction operation. Thus, the operation processing time can be changed without using the external circuit, resulting in increasing the speed.

Filed: 1987-11-20
Abstract: PURPOSE:To maintain the gasket-fixing surface of a cylinder at a constant level by masking the head-side plane of a cylinder to be joined via a gasket to a cylinder head and then plating the surface of the internal cylinder part of the cylinder. CONSTITUTION:After a cylinder 1 formed into the prescribed shape by means of casting is subjected to rough processing by means of machining, primary machining is applied to the surface of the internal cylinder part 2 of the cylinder and surfaces, such as head-side plane 1a, to finish the surfaces into smoothed surfaces of the prescribed surface roughness or below. Subsequently, the head-side plane 1a is masked with a masking member 10 and a web washer 20 is further placed on the above, by which the masking member 20 is allowed to tightly adhere to the head-side plane 1a. After pretreatment for plating is applied to the above in the above state by using an acid treatment solution to degrease and activate the surface of the internal cylinder part 2, the masking member 10 is detached and bead abutting surfaces 8 are piled up so that they are brought into contact with each other, and then, a plating layer is formed on the surface of the internal cylinder part 2. By this method, the surface roughness of the bead contact surface 8 can be maintained at the value at the time of primary machining.

Title: Laser drive circuit
Inventor: TANEMURA TAKASHI
IPC: H01S3/10
Filed: 1991-11-12
Abstract: PURPOSE:To improve the controllability of laser beam intensity by method wherein a differential amplifier circuit which outputs a first error signal, and an error detection circuit which outputs a second error signal, are provided, the first error signal is inputted to a laser drive part when the laser beam is modulated, and the second error signal is inputted to the laser drive part when the laser beam is not modulated. CONSTITUTION:An error detecting circuit 2 compares the level of SDIO of the light receiving output from an amplifier circuit 10 and the reference voltage (reproduction reference voltage VRR or erasing reference voltage VRE) sent from a changer 1, and it outputs an error detecting signal VEC showing the difference between the above-mentioned comparison. The error detecting signal VEC, sent from the error detection circuit 2, and the maximum value of error voltage VERH and the minimum value of error voltage VERL, sent from a differential amplifier circuits 14 and 15, are inputted to a switching apparatus 3. When erasing or reproducing, i.e., when the laser light is not modulated, the error detecting signal VEC, inputted to a laser drive amplifier circuit 16, is not subjected to the influence of a gain error and a linear error, because the signal VEC does not pass through a sample-and-hold circuit.

Title: Printing card guide mechanism in small-size printer
Inventor: YAMAGISHI KAZUHIKO
IPC: B41J13/12
Filed: 1987-11-24
Abstract: PURPOSE:To facilitate the insertion of a printing card, by mounting a rotatable shaft on the upper part of a printing head. CONSTITUTION:A printing card guide shaft 4 having a cross section shaped in star, angle, or knurl form is rotatably installed so that the projected part horizontally blocks the path of a printing card 5 and catches the upper end of an ink ribbon 3 vertically downwards. When the printing card 5 is inserted, the lower end of the printing card 5 abuts on the projected part of the guide shaft 4. By further pushing down the card 5, the guide shaft 4 starts rotating. By the rotation, the upper end of the ink ribbon 3 is made close to a printing head 1, and the card 5 is made close to a platen 2. In this manner, the collision of the lower end of the card 5 with the upper end of the ribbon 3 can be avoided, thus resulting in the smooth insertion of the card 5. Since the guide shaft 4 covers over the full width of the head 1, the card 5 abuts on the straight line part of the guide shaft 4 to be directionally corrected and inserted straight if being inserted inclinedly.

Title: Character display device
Inventor: ARAMAKI JUNICHI
IPC: G06F3/147
Filed: 1992-10-08
Abstract: PURPOSE:To facilitate input operation when characters are inputted on a display device which has only one line of display digits by determining one digit other than the most significant digit and least significant digit and blinking the digit at all times. CONSTITUTION:While character information is not inputted, a specific character in specific pattern which is not used as a character is blinked and displayed at the digit other than the most significant digit and least significant digit. When a character is inputted, the input character appears at the blinked digit and moves to a digit of higher order, so that a next character is inputted. For example, when a character input button 2 is pressed, the character is inputted to, for example, the 10th digit and shifted by one digit to the higher digit, and the special pattern is blinked and displayed at the 10th digit. When character input is performed with a character feed button 3, characters before and after a character which is selected and displayed are selected among ACSII codes with two character feed buttons 3. Then the selected character is blinked and displayed at the 10th digit and after the selected character is determined, the digits are feed with a digit feed button 4.

Title: Recording method using ink jet recording device
Inventor: KOYAMA TOSHIO
IPC: B41J19/14
Filed: 1992-10-08
Abstract: PURPOSE:To prevent density irregularities and bleeding from generating and thereby record a multi-color image satisfactorily by minimizing a beading phenomenon which generates between adjacent dots in a method for recording data to an OHP film using an ink jet recording device. CONSTITUTION:When printing data on a non-absorptive light-permeable recording medium such as OHP film, four dots (2X2 dots) is used as a single block, then dots of a single line are split and each dot in the block is printed in a single scan. When printing data, data is printed so that upper and lower/right and left adjacent dots are not continuously printed as far as circumstances permit, using a sequential order, that is, left top, right bottom, right top and left bottom in that order. Thus data of a single line is printed in four rounds of printing scan.

Title: Transfer aligner, and mask holding mechanism used for that device, and manufacturing method of semiconductor element
Inventor: HIRAYANAGI NORIYUKI
IPC: G03F7/20
Filed: 1999-10-19
Abstract: PROBLEM TO BE SOLVED: To dissolve the defect in an ordinary coulomb chucking of electrostatic chuck, which is lacking in chucking force, such as that the mask causes dislocation at start or control on a mask holder due to said short chucking and there is necessity to perform registering frequency at exposure, which is a large hindrance to increase the throughput, in a device for projecting and exposing the pattern on the mask, using a charged particle beam, or a method of projecting it. SOLUTION: It is so arranged that Johnsen-Rahbek chucking force works by lowering the volume resistivity of the holder part of a chuck part. At this time, the volume resistivity is controlled so that the influence of the charged particle beams, on an imaging orbit by this leaked current may come to a specified tolerable value or under.
