Title: Reticle
Inventor: YOKOTA KAZUKI
IPC: G03F1/84
Filed: 1999-03-16
Abstract: PROBLEM TO BE SOLVED: To define the region for inspection of defects, and to make a pattern to restrict a light-shielding region smaller than the resolution limit of a reduction stepper. SOLUTION: The slit 3 is composed of a line-and-space pattern P having a pitch smaller than the resolution limit of the reducing stepper. The line-and- space pattern P which constitutes the slit 3 is formed in stripes. Since the line- and-space pattern P is smaller than the resolution limit of the reducing stepper, an image can not be focused through the pattern P onto a wafer, and thereby no problem is caused for exposure. Even when the light shielding region 2 is illuminated by stray light produced by the reticle illumination optical system of the reducing stepper, the image of the line-and-space pattern P on the semiconductor wafer can be prevented. Since the line-and-space pattern P is a periodical pattern, it has high visibility for visual check with an optical microscope, and the region for inspection of defects can be defined.

Title: Densitometer
Inventor: HAMADA YOSHIYASU
IPC: G01N1/00
Filed: 1982-04-28
Abstract: PURPOSE:To detect the concentration of a liquid, by sampling a part of a liquid, and obtaining the temperature of the sampled liquid when the generation of gas is started, while reducing the pressure on the liquid. CONSTITUTION:A part of a liquid is sampled from a piping 1 through a by-pass pipe 2, and the pressure on the sampled liquid is reduced by means of a pressure- reducing valve 3. When the pressure is between a pressure P1 and a pressure P2, no gas is generated in the case where the liquid is supercooled. When the pressure drop by means of the pressure-reducing valve 3 is large, a gas is generated from the liquid to lower the liquid level in a tank 4. Therefore, decreasing the pressure-reduction amount by means of the pressure-reducing valve 3 from the time when the liquid level lowers, causes the generated gas to decrease in amount, thereby making it possible to find a point where the liquid level in the tank 4 no longer changes. The liquid level in the tank 4 is sensed by a liquid- level senser 7. Sensing the outlet temperature of the pressure- reducing valve 3 under the state where the liquid level in the tank 4 no longer changes, permits the concentration of the liquid to be obtained from a temperature T2 and the pressure P2. Accordingly, the concentration of the liquid can be detected by obtaining the saturation temperature through the changing of the pressure.

Title: Automatic focusing camera device
Inventor: HASEGAWA WATARU
IPC: G02B7/40
Filed: 1981-05-11
Abstract: PURPOSE:To ensure automatic focusing, by producing the signal which is generated for each lens set point from the distance signal obtained by the transmission and reception of the ultrasonic wave. CONSTITUTION:The ultrasonic pulse sent from a transmitter C is reflected from a subject and received at a receiver D. This received wave is compared with the reference voltage through a comparator F, and the distance signal is delivered. A counter I to which the distance signal is applied counts the frequencies oscillated from an oscillating device H and produces a binary output. This binary output is fed to a decoder J, and the binary output corresponding to the lens set point is fetched out to be stored n a counter M. Then the shifted position of the lens caused by a lens drivig device k is detected, and the device K is stopped when the lens shifted position is coincident with the contents of storage of the counter M. In such a way, automatic focusing is carried out.

Title: Low frequency amplifier
Inventor: MEJIKA KENICHI
IPC: H03F3/217
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To provide the low frequency amplifier in which a reception fault caused by noise produced in the case of amplifying an input signal is reduced. SOLUTION: A frequency divider 43 frequency-divides an oscillation signal FT from a reference oscillation circuit 41 based on a frequency division control signal BD from a frequency division control section 60 to generate frequency division signal CE. A sawtooth generating circuit 44 generates a sawtooth signal ST from the signal CE. The signal SC is used to drive a switching element of an amplifier 46 to amplify the signal SC. A low pass filter consisting of a coil 47 and a capacitor 48 is used to obtain an amplified signal SA from the signal SC and the signal SA is fed to a speaker 50. The frequency of the signal SC is varied by selecting continuously or discontinuously the frequency division ratio with the signal BD from the control section 60.  Since frequencies of a fundamental component and harmonic component of a switching noise from the amplifier 46 are varied, the amount of noise per unit time of a prescribed frequency is reduced.
