Patent JP-H0490552-A (JP)
Title: Exposure device
Inventor: HOSHI JUNICHI
IPC: G03F7/20
Filed: 1990-08-02
Abstract: PURPOSE:To execute exposure in an extremely short time and to drastically reduce the cost of manufacture by irradiating a sample with light while a mask is moved when a shutter is under an open state. CONSTITUTION:When the sample 9 is exposed, a light source which is not shown in a figure is turned on and the shutter 2 is irradiated with incident light 1. Next, a control signal is outputted to the shutter 2 and a motor 6 from an interlocking circuit 10 and the shutter 2 and the motor 6 are synchronized. That means, the motor 6 is driven under a state that the shutter 2 is closed and the mask 3 is moved in the direction of an optical path by it. In such a case, since the shutter is under the open state, the sample 9 is irradiated with the incident light 1 and it can be successively exposed. That means, since the exposure is executed while the focusing position of an optical system 7 with respect to the sample 9 is changed, the exposure equal to a conventional FLEX method is executed by one-time exposure and the sample whose flatness is deteriorated is exposed in an extremely short time.

IPC: C22F1/00
Filed: 1985-09-18
Abstract: PURPOSE:To easily provide high resistance to damage by corrosion to a heat exchanger tube made of a high-Ni austenitic alloy by heating the damageable part of the tube under prescribed conditions. CONSTITUTION:The damageable part of a heat exchanger tube made of a high-Ni austenitic alloy and having sensitivity to damage by corrosion is heated at 650-750 deg.C for >=1min.

IPC: F16K31/04
Filed: 1994-08-05
Abstract: PURPOSE:To facilitate the adjustment of a flow characteristic by forming a first valve seat at an outflow passage, a second valve seat at a main outflow passage, and a first and a second valve parts, forming pairs with the first and second valve seats, at a driver, and controlling the flow rate of a fluid to the main and auxiliary outflow passages. CONSTITUTION:When an engine is cooled, a valve body 19 is moved upward by a stepping motor, so that a main valve 24, a pressure control valve 27 and an auxiliary valve 29 are placed in the opened state. The outflow quantity, flowing from outlets 14, 17, of sucked air flowing into a valve chamber 5 thereby becomes the maximum outflow quantity determined by orifices 13, 16, and the total outflow quantity also becomes the maximum. When the engine starts warming up, the opening of the valves 24, 27, 29 is reduced, and the outflow quantity from the outlet 17 is determined by the clearance area of the auxiliary valve 29, and the total outflow quantity is reduced only by the reduced quantity part of the outlet 17. When the engine is warmed, the auxiliary valve 29 is closed, the difference between the valve chamber 5 and the outlet 17 is reduced by the pressure control valve 27, and the total outflow quantity is controlled by the main valve 24. In the case of not needing auxiliary air, the main valve 24 is closed to cut off outflow to the outlets 14, 17. An outflow characteristic can be thereby adjusted easily.

Title: Holder device for edge tool
Inventor: BUIRII BIYUUTEIKOOFUA
IPC: B23B31/107
Filed: 1984-09-28
Abstract: A tool support, or an extension or reduction part holding a tool support, is held by its shank in an axial bore of a socket of the tool-holding device. The socket has one or more further bores, the longitudinal axes of which each form an angle of from 0 DEG  to about 5 DEG  with a straight line perpendicular to the longitudinal axis of the socket. A setscrew disposed in one such further bore cooperates by means of a beveled or faceted surface at its lower end with a chucking surface running on the outside of the shank at an angle to the longitudinal axis thereof. Another setscrew may cooperate with a second such chucking surface forming an angle of about 45 DEG  with the first chucking surface. Faultless force-locking and a bias are produced between the end faces of the socket and of the tool support, thus making it possible to combine even large, heavy boring tools with universally usable tool-holding devices inasmuch as there is sufficient resistance to torsional stress between the tool-holding device and the tool support.

Abstract: PURPOSE:To attain sure communication when a remote control device moves under an environment where a radio wave state is deteriorated by sending a signal representing a specific location to the remote control device at the specific location where the sensitivity is low so as to increase the communication sensitivity of the remote control device. CONSTITUTION:A communication means communicating control information as a radio wave is provided to each of an equipment main body A and a remote control device R. Then transmission means E1, E2 sending signals representing specific locations are provided at the specific locations where the sensitivity of communication with the equipment main body A is estimated to be low and the remote control device R is provided with a reception means receiving signals from the transmission means E1, E2. As a communication means of the remote control device R receives the signals from the transmission means E1, E2, the communication sensitivity is increased. Even when the normal value of the communication sensitivity is set comparatively lower to the communication means of the remote control device R, communication is attained surely when the remote control device R moves under environment with a bad radio wave state.

Filed: 1989-08-09
Abstract: PURPOSE:To attain focusing with high accuracy even at low brightness by fixing an amplification gain at a correction gain at a low brightness when an image pickup video signal level is a proper level and executing the focusing at the gain fixed state. CONSTITUTION:When an object is in a dark environment and a shutter speed is longer than 1/60sec even when the aperture is opened to obtain a proper exposure, a measurement of a photometry circuit 25 is very small and a gain control circuit 41 varies the gain of a variable gain AMP 42 to amplify a pickup video signal and the image pickup video signal after video amplification is fed back to a gain control circuit 41 which controls the gain so as to make the pickup video signal level to a prescribed proper level. When the pickup video signal level reaches the proper level once, a gain control signal of the gain control circuit 41 reaches the lock state. Then an automatic focus circuit 30 is not operated before the gain control signal from the gain control circuit 41 is not locked. Thus, the focusing with high accuracy is kept.
