Title: Display device in finder of camera
Inventor: SUZUKI RIYOUICHI
IPC: G03B17/20
Filed: 1979-12-17
Abstract: PURPOSE: To decrease troubles and make size smaller and cost lower by the constitution consisting in integrating p-n junction parts forming LEDs and field effect type switching means as well as resistors and combining these to a single semiconductor integrated circuit.  
     CONSTITUTION: The potential gradient shown by a straight line L is produced by the induced voltage V 2  of a voltage source 15 in a resistance type insulation gate 11. In a region where the voltage exceeds predetermined threshold voltage V-th out of the potential gradient, an inversion layer is formed below the gate 11, and said part goes ON. Thereupon, current flows through a p type semiconductor 13, divided n type semicondcutors 12aW12n, and further the inversion layer under the gate 11, thus causing the parts of the divided n type semiconductors 12aW12n to emit light. When the output voltage value V 1  of a variable voltage generating source 14 changes in this state, the straight line L of the potential gradient parallel moves vertically, and the point of intersection with the threshold voltage V-th also moves, thus the change in information is analogically displayed.

Title: Method and apparatus for cleaning and drying substrate
Inventor: GOTOU KAZUNOBU
IPC: H01L21/304
Filed: 1989-06-27
Abstract: PURPOSE:To obtain more cleaner substrate by reducing the pressure of hot water wherein the substrate is immersed, boiling the water, cleaning the substrate, and further rinsing out the substrate by using pure water. CONSTITUTION:Hot water is injected into a chamber 1 wherein a substrate W is contained. Then, the pressure in the chamber 1 is decreased to the vapor pressure or less, and the hot water is boiled. Then pure water is injected into the chamber 1, and the substrate W is rinsed out. Thereafter, the water in the chamber 1 is drained, and the inside of the chamber 1 is evacuated to the vacuum state. Namely, since the substrate W is cleaned by the pressure reduction and the boiling of the hot water, the cleaning effect of the substrate with the hot water becomes further high. Since the substrate is rinsed out with the pure water and dried in the vacuum state of the chamber after the cleaning by the boiling, the more cleaner substrate W is obtained. The cleaning effect of the substrate W is enhanced in this way, and the more cleaner substrate can be obtained.

IPC: G01V8/12
Filed: 1992-06-23
Abstract: PURPOSE:To prevent the occurrence of such a state that the same state as a human body detecting state continues for a long time when a human body leaves a detecting area by comparing a detecting signal outputted from an infrared detecting element with a prescribed threshold. CONSTITUTION:A comparator circuit 5 compares the output level of an infrared detecting signal from a band-pass filter circuit 4 with either one of the two kinds of thresholds respectively set in threshold setting circuits 8a and 8b outputted by means of a change-over switch 10. When the infrared detecting signal exceeds the threshold, an delay circuit 6 delays the outputting timing of the detecting signal by a fixed period of time. When an output control section 7 receives a prescribed signal from the circuit 6, the section 7 outputs a relay signal for turning on lighting equipment. When the reception of continuous output signals from the circuit 6 is discontinued, the section 7 immediately outputs another relay signal for turning off the lighting equipment so as to make an infrared detecting element 2 to discriminate that no human body exists.
