Title: Light detection type rotation detecting mechanism
IPC: G01P3/486
Filed: 1992-03-26
Abstract: PURPOSE:To realize space saving and miniaturization and cost reduction by constituting this mechanism such that the outgoing light from a light emitting element enters intermittently a light receiving element through the opening of a shield plate, the slit of a rotor, and the opening of a board, and that the light receiving element produces pulse signals. CONSTITUTION:The light emitted from a light emitting element 41 passes the slit 61 for control of the light path of a shield case 60, and is transmitted when the slit 32 at the margin 31 of the rotor rotates and is aligned with the optical axis of the light, and passes through the slit 51 for control of the light path of a board 50, and enters the light receiving element 42 provided at the rear of the board 50. That is, pulse signals are generated and the rotational speed is detected by the light emitted from the light emitting element 41 intermittently entering the light receiving element 42, accompanying the rotation of a rotor 30. This way, the outside dimension of the rotor 30 is cut down and also time gap between the board 50 and the rotor 30 is lessened by arranging the rotor 30 and the board 50 between the light emitting element 41 and the light receiving element 42, thus the driving system is miniaturized and simplified.

Title: Comb-line filter
Inventor: KOBAYASHI MASAAKI
IPC: H03H15/00
Filed: 1984-04-05
Abstract: PURPOSE:To improve S/N of an video signal without decreasing a vertical resolution by detecting the level of a chrominance signal and controlling the amplitude of such as an amplitude limiter fitted with a control terminal to increase or decrease in level in accordance with the magnitude of the detected output. CONSTITUTION:A luminance signal Y and a chrominance signal C are inputted to input terminals 1 and 11, respectively. The level of the chrominance signal C is detected as a signal A in an amplitude detection circuit 10. The signal A is inputted to a control terminal of an amplitude limit circuit 8. At the time of a high level of the signal A, said circuit 8 is controlled so that a limit amplitude level can be higher, whereas at the time of a lower level of the signal A, the control amplitude level is so controlled to become lower or zero. Thus the mixed modulation distortion caused by an included chrominance signal can be removed from the reproduced luminance signal only when the level of the reproduced luminance signal is lower, and the level of the chrominance signal is higher (namely, only when the mixed modulation distortion is large).

A milling cutter 3 is a slot milling cutter and as milling is given to the rotary body 11 with this cutter 3, slots 16 are formed thereon. By adjusting the depth of the slots 16, the milling quantity can be delicately controlled to carry out the correction of unbalance with high accuracy. Hence, the milling cutter 3 is suitable for the rotary, body 11 having a small unbalance quantity and the recorrection after the initial correction.

Title: Method of overlay exposure
Inventor: OCHIAI YUKINORI
IPC: H01L21/027
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of overlay exposure with multiple times of exposure. SOLUTION: A first pattern and marks 2 for position detection are formed by an exposure such as light exposure and an intermediate treatment such as etching. A wafer is partitioned into correction fields 3 corresponding to the marks 2 for position detection. The position of the mark 2 at each correction field 3 is detected and distortion is found. The position of exposure is determined by correcting the distortion, and a second pattern is exposed to light with an electron beam. The distortion produced during the previous exposure and intermediate treatment is found in advance. The marks 2 are distributed densely in the parts where the distortion is large and the area of the correction field 3 is small. Accordingly, as distortion in a part is larger, correction in each correction field can be made in detail.  On the other hand, in a part where distortion is small, workability in high because there are a few correction fields in a large area.

Abstract: PURPOSE: To realize the detection for the magnetic substance regardless of the size of the magnetic substance, by providing the magnetic field detector having the directivity in the right-angle coordinates axial direction and then giving the operation to the output magnetic field component of the detector.  
     CONSTITUTION: Magnetic field detector X is attached vertically to the area under horizontal acrylic plate 1. And small magnet 4 is put on plate 1 and in parallel to direction X and then shifted toward X to be shifted sequentially from the area on axis X toward direction Y to be then shifted toward X. In this case, the directional cosines l, m and n of magnetic efficiency M to axis X, Y and Z feature l=0 and m=n=0 each since efficiency m is turned toward X. And maximum value HZ max  of magnetic field component HZ of axis Z features 48M/(25×5 1/2 ×Z 3 ); while magnetic field component HX of axis X features M[(3X 2 /r 5 )-(1/r 3 )]. Then the ratio is obtained between HZ max  and HX to obtain the side distance. Accordingly, the detection becomes possible in case the magnetic substance passes through a fixed range of the side distance from the side of the detector and regardless of the size of the passing magnetic substance since the value of the ratio can be satisfied even with use of the small magnet having the different magnetic efficiency.

Title: Ozone water supplying system
Inventor: NAGAHIRO JINZO
IPC: B01J4/00
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To gently carry out ozone water in a heat insulated cold reserving vessel in natural discharge state by the gravity without springing out in feed by providing an ozone gas discharge pipe from an ozone water storing sealed vessel with a second solenoid valve which is laid in open state when a first solenoid valve is laid in open state. SOLUTION: When a hand is placed under a faucet, it is caught by an automatic faucet sensor to open a solenoid valve, and ozone water 12 within a heat insulated cold reserving vessel 20 is taken out. Since the pressure of an ozone gas pressure chamber 38 within the heat insulated cold reserving vessel 20 is automatically regulated and held within a prescribed range, there is a possibility of the ozone water 12 springing out. Therefore, a solenoid valve 43 operated in interlocking with the signal of the automatic faucet sensor is disposed in the bypass circuit of a pressure relief valve 42. The solenoid valve 43 is laid in open state at the same time when the solenoid valve mounted on the conduit of the faucet is opened.  Thus, the pressure ozone gas in the ozone gas chamber 38 is discharged to an ozone killer 41 through the solenoid valve 43, and laid into the atmospheric pressure state.

Abstract: PURPOSE: To make the alarm unit or an annunicator sound at the same time with earthquake occurrence and accelerate human emergency evacuation by amplifying the vibration of a pendulum by the application of a lever, operating the switch of the alarm unit or annunciator, and powering on it. CONSTITUTION: The function of a seismometer is made sharper and the power switch of the alarm unit or annunicator is turned on by the movement of a part corresponding to the pointer of the seismometer. This means is installed roughly horizontally and then a pendulum weight 6 is moved in free directions of 360 deg. by a shake of an earthquake. Once the shake of the earthquake causes the pendulum body 8 to move, relative motion is generated at the upper end 3 of a support rod 2 around a free tripod 1 as a fulcrum by the motion of the pendulum weight 6 which tries to keep a stationary state, and then a switch support plate 4 is moved to remove brakes on motion for turning on the power switch, thereby powering on the alarm unit or annunciator. Consequently, the earthquake occurrence is indicated as quickly as possible and the early people evacuation is accelerated day and night.
