Title: Thin film magnetic head and magnetic disk device
Inventor: OKADA TOSHIHIRO
IPC: G03F7/20
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To deepen a focus depth to form desired patterns even for a thick resist by using a deformation illuminating method such as a zonal illuminating method and four-aperture illuminating method, in the exposing process wherein the resist having a film thickness of the specified value or more is used for a reticle with an isolated pattern. SOLUTION: In the case of a zonal illuminating method, a zonal illuminating diaphragm whose ratio of the zonal inside radius to the zonal outside radius is 1/2 or 2/3 is used. Although the zonal illuminating diaphragm whose radius ratio is 2/3 has a focus depth effect larger than the same whose radius ratio is 1/2, since the former has a fault that its illuminance distribution becomes larger than that of the latter, either of them is selected in accordance with a process. In the case of the four-aperture illuminating method, since improvement of a focus depth and irregularity of illuminating are changed by the ratio of dimension (a) to (b) of the pattern of the four-aperture illuminating diaphragm, the balance of the ratio is optimally selected.  In an exposing process, one kind or more of the flex method executing exposure while successively changing the focus or the method using a half-tone type mask for a reticle are used, and a resist film in the exposing process is preferably specified to <=2 μm thickness.

Title: Water temperature measuring/displaying system
Inventor: NAKAMURA TSUNEO
IPC: G01B17/00
Filed: 1993-05-21
Abstract: PURPOSE:To facilitate the recognition of the temporal change of water temperature at each depth by radiating ultrasonic pulses into the water, receiving the reflected wave at each depth, measuring the water temperature at each depth based on the difference of propagation speed, and then displaying thus measured water temperatures three-dimensionally. CONSTITUTION:A transmitter 2 radiates ultrasonic pulses vertically downward and a receiver 3 measures the arriving time (t) of reflection wave from a measuring point L while varying the angle Q of depression. Assuming L1-L5 are measuring points and T1-T5 are water temperature, the time t1 when the ultrasonic wave arrives at the receiver 3 set with an angle of depression Q1 can be represented by a formula; t1(La+Lc)/C1(T1), where La is the distance between the transmitter 2 and the point L1, and Lc is the distance between the receiver 3 and the point L1. Consequently, C1(T1) can be calculated by measuring the arriving time t1 and the water temperature can be determined with reference to a sound velocity correction table. When the measurements are repeated and the variation of water temperature (X axis) at each depth (Y axis) is displayed three-dimensionally on the time axis (Z axis), temporal variation of water temperature at each depth can be grasped at a glance.

Abstract: PURPOSE: To improve the tightness of the frame and prevent rain or others from penetrating into the inside by forming the frame made of synthetic resin to the form U in cross section and decreasing the gap of the upper and lower sides of the frame to an adequate size in a solar heat collector having a frame.  
     CONSTITUTION: A solar heat collector is arranged such that upper opening of an external box 1 including a flange 2 at the upper end of its side wall is enclosed with a transparent plate 3 for lighting, and the periphery portion of the transparent plate 3 and the flange 2 are held to be contacted tightly by a frame 4. In this arrangement, the frame 4 made of synthetic resin is formed into the form U in cross section and a lower side of the U form frame is bent upwards so as to make the gap between the upper end of the bent portion and an upper side of the U form frame less than the thickness of the superimposed flange 2 and transparent plate 3. In such a way, the frame 4 is not rusted and maintains the safety because it is made of synthetic resin and its lower end does not include the sharpened edge. In addition, elasticity produced at the lower end of the frame gives the superior tightness, so that it is possible to prevent rain or others from entering into the inside.

When the periodical transmission of the 2nd fixed period cannot be normally executed, periodical transmission is executed between two slave nodes at a 3rd fixed period slightly longer than the 2nd fixed period. When the periodical transmission of the 3rd fixed period cannot be normally executed, a load is driven through a backup signal line as a final means.

Abstract: PURPOSE:To fetch efficiently a necessary signal and to make signal processing easy, by scanning linearly a photodetection surface in a prescribed angle range in association with a working point and detecting the working line in accordance with the fetched video signal. CONSTITUTION:A video camera 11 is applied with a period signal from a frequency signal generating circuit 12 and clock pulses from a clock pulse generating circuit 13 and applies a video signal to a comparator 14 by scanning the photodetection surface around the working point in, for example, a circular shape. The comparator 14 compares a set voltage and the video signal and applies the output thereof to a gate pulse generating circuit 16. The circuit 16 applies a gate pulse as one input to an AND gate 17 in accordance with the output of the comparator 14 and the period signal. Since clock pulses are applied as the other input to the gate 17, the clock pulses corresponding to the pulse width of the gate pulse are outputted from the gate 17. Thus an arithmetic processing part 18 makes simple arithmetic processing by counting the number of the clock pulses thereby calculating the direction of the working line.
