Title: Spray developing method
Inventor: YAMADA KIYOFUMI
IPC: H01L21/30
Filed: 1984-08-31
Abstract: PURPOSE:To prevent the remaining of a resist and the generation of uneven colors without using an intermediate rinse liquid by increasing gradually the mixing ratio of a good solvent with a bad solvent in a preparatory stage for development and decreasing gradually said mixing ratio in an end stage for development. CONSTITUTION:The mixing ratio of the bad solvent 8 and good solvent 7 of a developer mixture composed of the good solvent 7 and the bad solvent 8 used for subjecting a substrate 1 provided with the exposed resist to spray development by a nozzle 22 is gradually decreased from the min. value to a prescribed value by flow rate regulators 11 and 12 under the control of a control device 6 in the preparatory stage for the development, is kept maintained substantially constant at the above-mentioned value in the normal stage for the development and is gradually decreased from the prescribed value mentioned above to the min. value in the end stage for the development. The remaining of the resist and the generation of uneven colors is prevented by changing the mixing ratio of the good solvent with the bad solvent in each stage of the development in the above-mentioned way. The development under the control of the mixing ratio is made possible by adjusting the flow rates of both solvents 7 and 8 with a detector 18 and the control signals S2, S3 thereof. The on-site operation is made easy as well.

Title: Ink jet printing apparatus
Inventor: YANAKA TOSHIYUKI
IPC: B41J2/21
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To perform printing in which uniformity of a color at a portion forming a ground such as a background in an image is favorable, in an ink jet printing apparatus. SOLUTION: An ink jet printing apparatus uses a high-resolution head 1001H whose discharge quantity is small and a low-resolution head 1001L whose discharge quantity is large. With reference to an image which should be printed, a portion forming a ground is separated from other portions by an image separation unit 1009, and the ground portion is printed by the low-resolution head 1001L after being processed by an image processing unit 1008 and a head control unit 1006. By this method, large dots are formed at the ground portion, therefore, gap portions among the dots become small, and a ground color can be made uniform.

Title: Ultrasonic distance measuring equipment
Inventor: SAKAI AKIRA
IPC: G01S15/08
Filed: 1994-08-05
Abstract: PURPOSE:To reduce the dispersion in measuring distance and perform a precise measurement by regarding the point of time of the temporal center-of-gravity position of the waveform signal of a reflected wave as the receiving time of the reflected wave. CONSTITUTION:In an ultrasonic distance measuring equipment 1, a transducer 2 emits an ultrasonic wave to the surface A of a matter to be measured and receives the reflected wave to determine the attaining time from the emitting time to the receiving time. This time is divided by 2 and multiplied by sound velocity, whereby the distance to the surface A of the matter to be measured is determined. When the surface A of the matter to be measured is inclined to the emitting direction of the ultrasonic wave, for example, the width in the time axial direction of a waveform signal (b) in the reflected wave to a transmitting signal (a) is extended. In a signal processing device 6, the center-of- gravity position (central position) B in the time axial direction of the waveform signal (b) is regarded as the receiving time, and the distance L to the surface A of the matter to be measured is determined by operation on the basis of this receiving time. Thus, the obtained measured distance is hardly dispersed, and a stable measurement can be performed.

Abstract: PURPOSE:To eliminate an unsuccessful photograph, and to allow a photographer to quickly recognize the abnormality of a camera by detecting the opening/ closing state of a barrier and returning a movable lens-barrel to a retractive position, when the barrier is closed. CONSTITUTION:The opening/closing states of the barrier 17 by the delivery of a lens unit 10, are obtained by the count of a prescribed pulse. When the lens unit 10 is delivered in the opening state of the barrier 17, the barrier 17 is opened, so that the b-part of the barrier 17 for checking the opening/closing of the barrier 17, is escaped from the working area of the a-part of the lens unit 10. Therefore, the prescribed pulse is counted up, to deliver a lens by a specific amount. At this time, when the barrier 17 is closed, the b-part of the barrier 17 is left on the working area of the a-part of the lens unit 10. Consequently, the a-part butts on the b-part while the lens unit 10 is delivered, the operation of the lens unit 10 is stopped, and the rotation of a pulse plate 14 is stopped, as well. Thus, since the lens-barrel is not required to project, the lens-barrel is returned to the retractive position.
