Title: Comparator and proximity sensor
Inventor: FUJIMOTO KIMITADA
IPC: H03K17/95
Filed: 1994-09-14
Abstract: PURPOSE: To change the output of a differential amplification comparator at high speed. CONSTITUTION: Transistors Q13, Q14 comprise a differential amplifier circuit, and reference voltages are set to V1, V2, respectively. Only the AC component of an input voltage is superimposed on the reference voltage V1 through a capacitor C2. When the voltage exceeds the reference voltage V2 and the collector current of the transistor Q13 begins to increase, the transistor Q12 is also turned on and the difference between voltages V1 and V2 is reduced. Also, a bias current to the differential amplifier circuit is increased since the current to a transistor Q15 is increased by a transistor Q11. Therefore, the output can be inverted at high speed.

Abstract: PURPOSE:To facilitate the movement of fishes, by a method wherein a vertical shaft in a fish pass tower is communicated with a fish call-in port with a gate on the downstream side through an oblique pit, a fish discharge port with a gate, through which the dam storage side is communicated with the vertical shaft, is provided in the fish pass tower, and a water dispersing port and an illuminating lamp are formed in and attached to the oblique hole and the vertical shaft. CONSTITUTION:When sluice gates 15-17 on the upper stream side are fully closed, a closing gate 7 on the downstream side is fully opened, a water dispersing port 23 in an oblique pit 6 is opened, and an illuminating lamp 22 is opened, fishes gather rather to the up-stream side than the gate 7 in a call-in port 5. When the gate 7 is closed, a water level in the oblique pit 6 is increased resulting from water dispersion and is increased when the illuminating lamp 22 under a water surface is put OFF, and fishes gather to a water surface and are moved to the vertical shaft 4. Since, within the vertical shaft 4 also, water is drained through the water dispersing port 23 and the illuminating lamp 22 is lighted ON, the fishes are raised with the increase in the water level in the vertical shaft 4. When the water level in the vertical shaft 4 is brought into coincidence with a storage water level in a dam, the gates 15-17 are opened, the illuminating lamp 22 is put OFF, and water dispersion is stopped to cause the fishes to escape in a reservoir 3.

Title: Zoom lens
Inventor: MIHARA SHINICHI
IPC: G02B13/18
Filed: 1987-10-02
Abstract: PURPOSE:To shorten the overall length of a lens system, to hold the front lens diameter small, and to decrease the number of elements by moving 2nd and 3rd groups in the same direction over the entire zoom area while varying their relative gap so that power variation and a focus position are held constant. CONSTITUTION:The 2nd and 3rd groups are moved in the same direction over the entire zooming area while their relative gap is varied so as to hold the power variation and focus position constant. The 2nd and 3rd groups of the zoom lens are put in such motion that the gap between the 2nd and 3rd groups is maximum at intermediate focal length, so the gap is minimized at the telephoto end where the gap is reduced most as to the space. Further, the 3rd group is disabled to be inverted in moving direction while varying the power from the wide-angle end to the telephoto end, so the gap between the 3rd group and a fixed group behind it can be minimized at the telephoto end. Consequently, the zoom lens consists of an extremely small number of elements, the overall length and front lens diameter are small, and the size and weight are reducible.
