Title: Printer image read method, image reader and its light source controller
Inventor: KATANO KIYOSHI
IPC: G06T1/00
Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To enhance the job efficiency by preheating a light source with a preheater before a white reference value is detected and allowing a lighting time calculation device to calculate a lighting time to preheat the light source based on a prescribed temperature so as to reduce a wait time of the user required for preheating. SOLUTION: An original read function is provided to the printer by mounting a scanner head cartridge 800 to a printer unit section 219. When the scanner head cartridge 800 is mounted to the carriage, preheat processing of an LED 902 is started. At first a temperature in the printer is read and a time required for preheating is calculated based on a cross reference between the printer temperature and the preheat time stored in advance in a ROM. Then the LED 902 is lighted for preheating. After the lapse of the preheat time, the LED 902 is switched to a warm keeping lighting, the printer temperature is read, whether a power supply is a commercial AC power supply or a battery power supply is detected, and the period of lighting/extinguishment and a lighting current are detected accordingly.

Filed: 1986-11-18
Abstract: PURPOSE:To shorten a time for a track 0 detection by detecting a track 0 with the aid of monitoring the input time of a servo information to a spindle index signal or a dividing pulse by a track 0 detecting means. CONSTITUTION:The spindle index signal is generated, being synchronized with the rotation of a spindle motor 15, from a spindle index sensor 3, and is given to a timing means 6 and a CPU 2. The means 6 generates the dividing pulse of 1/4 period against 1 period of this signal, and simultaneously, counts the dividing pulse, calculates a count value, and supplies the dividing pulse and the count value to the CPU 2. On the other hand, a signal, read from a disk surface 1 by a magnetic head 4, is supplied to a synchronizing pulse detection circuit 5, and the synchronizing pulse is transmitted to the CPU 2 from the circuit 5, and next, the servo information is supplied to the CPU 2. Accordingly, by monitoring the time since the spindle index signal or the dividing pulse is inputted to the CPU 2 until the servo information is inputted, the track 0 detection can be performed in a short time.

Title: High precision rib and forming method therefor
Inventor: MASE KEIJI
IPC: H01J9/02
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To provide high precision ribs formed narrower, more uniform and higher on a substrate, and an efficient forming method therefor. SOLUTION: Low fusing point glass paste with blasting property is applied to the whole surface of one side of a substrate to form a low fusing point glass layer 12. Low fusing point glass paste with blasting resistance is applied to the surface of the low fusing point glass layer 12 to form resist layers 13 in a pattern. When grinding/polishing/cleaning material is jetted from the surface side of the low fusing point glass layer 12 for blasting, the whole low fusing point glass layer 12 excluding the lower layers of the resist layers 13 is eliminated being ground by the grinding/polishing/cleaning material so as to form ribs 14 consisting of the low fusing point glass layers 12 and the resist layers 13. The ribs 14 are formed narrow but high and uniform.  Without separating the resist layers 13, the resist layers 13 and the low fusing point glass layers 12 under the resist layers 13 are sintered and solidified to form the ribs 14. The resist layer 13 corresponds to 10-15% or the height or the rib 14 and becomes a part or the rib 14 so as to contribute to the formation of the high precision rib.

Filed: 1988-10-28
Abstract: PURPOSE:To form a minutely formed pattern having perpendicular sectional shape by irradiating a whole surface of a positive photoresist as first layer with ultraviolet rays, coating the surface with a positive photoresist for a second layer, and irradiating the second layer selectively with ultraviolet rays through a photomask. CONSTITUTION:An alkali-soluble positive photoresist 4 is obtd. by irradiating a substrate 1 coated with a positive photoresist for a first layer with parallel ultraviolet rays uniformly for a short time. Then, a positive photoresist 5 for a second layer is coated to ca.1/2 of a desired film thickness so as to make the surface of the second layer of the positive photoresist 5 flat, and the photoresist 5 is prebaked. The area of the positive photoresist is converted to an alkali-soluble area 8 when the positive photoresist is irradiated with UV rays 6 such as g-line, etc. through a photomask to ca.3/4 degree of irradiation executed usually for a single layered resist. In this stage, the photoresist can be made selectively soluble sufficiently with a small dose of radiation applied to the first layer. Thus, a vertical sectional shape of the positive photoresist for the first layer is formed, and the photoresist is formed more minutely.
