Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a display apparatus which can display bright projected images without degrading the display quality of the projected images and without employing a projection lens with a large diameter having a small F-number. SOLUTION: A light source device 2 comprises a first light source lamp 20A, a second light source lamp 20B, and a light-guiding part 24 which connects a first luminous flux W1 from the first light source lamp 20A and a second luminous flux W2 from the second light source lamp 20B with each other and emits this connected flux. By the light-guiding part 24, a part W1a of the first luminous flux W1 and a part W2a of the second luminous flux W2 are emitted as a light flux which connects between the fluxes emitted from the light sources 20A and 20B.

Title: Surface geometry measuring apparatus
IPC: H01J37/28
Filed: 1992-03-27
Abstract: PURPOSE:To detect geometry of a surface to be measured from a size of a spot of reflected light by a method wherein if a probe is displaced due to interatomic force according to geometry of the surface, a thin film part is elastically deformed and curvature of an concave surface made by its reflecting face varies. CONSTITUTION:Measuring light L is emitted from a light projector 15 perpendicularly to a plate when a thin film part 12 is flat. When the thin film part 12 is elastically deformed in a concave shape due to interatomic force generated between a probe 14 and a surface 16 to be measured, reflected light P from the thin film part 12 is condensed by a concave reflecting film 13 to be received by a light receiver 17. The light receiver 17 matches its center with an axial center of the probe 14 between the reflecting film 13 and the light projector 15 and is integrally provided with a support member 11. A position of a focus F when the reflecting film 13 is deformed in a concave shape differs depending on a distance between the probe 14 and the surface 16 to be measured. Therefore a displacement amount of the probe 14, that is geometry of the surface 16 can be detected from a spot diameter of the reflected light S detected by the light receiver 17. This measuring apparatus has a displacement direction of the probe 14 matched with a detected direction of the displacement, so that an error in measurement can be reduced.

Title: Image pickup device
Inventor: NISHIDA YOSHIHIKO
IPC: G01B11/00
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent the configuration from being made large and the updation cycle from being long-term and to permit high resolution at a broad visual field angle by outputting a synthetic image signal that expresses an image obtd. by synthesizing images by 1st and 2nd image picking up means in such a manner that an area where an image by the 1st image picking up means corresponds to an image by the 2nd image picking up means is replaced by the image to the 2nd image picking up means. SOLUTION: A 2nd image picking up means 16 has a 2nd detector 24 that is the same as a 1st detector 22 and also a 2nd optical image forming system 23 has a higher image formation magnification than a 1st optical image forming system 21. Thus, although the means 16 has an image pickup area that is smaller than a 1st image picking up means 15, it can convert an infrared optical image received from an area of the same visual field angle into an image signal with high photodetector density, i.e., high pixel density. In other words, the means 16 obtains an image that is picked up with higher resolution than the means 15 by reducing the visual field angle per pixel, that is, instantaneous visual field angle.

Abstract: PURPOSE: To reduce the area at an opening for contact by forming a side wall insulation layer on the vertical surface while leaving a coating layer on a conductive structure through anisotropic etching such that the outer surface of the side wall insulation layer serves as the side wall of a contact hole. CONSTITUTION: After an isomorphic oxide layer 64 is formed on a substrate by forming source/drain regions 58, 60 and 62, anisotropic etching is performed on the surface of a structure on the substrate.

Title: Cap for container
Inventor: DAICHO TAKAO
IPC: B65D47/06
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a cap which is not removed by a force working from the outside. SOLUTION: For the present cap, an inner cap 4 for fixing to the mouth of a container is fitted to the inside of an outer cap 3. As the outer cap 3 is pressed toward the inside, fixation is made with a projected part 7 of the outer cap engaged with an indent of the inner cap 4 and an indent of the outer cap 4 engaged with a projected part 9 of the inner cap 4. The projected part 7 of the outer cap projects at an angle of 90 deg. in the direction of engagement while projecting diagonally in the direction of disengagement. Therefore, even though the indent of the inner cap 4 is slightly engaged with the projected part 7 of the outer cap 3 while being unfixed, a force applied to the outer cap 3 is not transmitted to the inner cap because of slippage and thereby, the inner cap 4 is not detached.

Title: Estimating unit for flow amount to reservoir
Inventor: HAMA NOBORU
IPC: G01F1/00
Filed: 1979-06-08
Abstract: PURPOSE: To enable to estimate accurate flow amount stably without being effected with present discharge amount even with water level change, by obtaining the flow amount through the addition of the flow rate per unit time and the average discharge by means of the operation unit.  
     CONSTITUTION: If water level change is present with N 2  times of discharges, the water storage amount VH 3  to the present water level H 3  is obtained with the H-V converter 2. Next, after the first operation unit 3 obtains the increment or decrement of stored water per one time from the water storage VH 3  and the storage VH 2  before, the flow rate per unit time, (VH 3 -VH 2 )/(N 2 T) is obtained from the time T required for water level change. Next, since the fourth operation unit 7 outputs the average discharge QV 2  while the water level changes from H 2  to H 3 , the flow is obtained by adding the flow rate per unit time and the average discharge QV 2  by using the third operation unit 5. Thus, stable and accurate flow amount can be estimated without being affected with the present discharge during the water level change.

Abstract: PURPOSE:To reduce the packaging space of a driving IC as far as possible and to enhance reliability, etc., by bringing a resin agent for protecting this IC for driving into contact with a substrate coupled to a liquid crystal panel in order to input an electric signal to the IC for driving. CONSTITUTION:The input flexible substrate 8 is first electrically and mechanically fixed.

The distance L from the end face of the liquid crystal glass to the outer peripheral side of the IC is made small. The stresses by the high temp. and the high pressure are no longer applied on the bump parts 6, 6' of the IC 5 by mounting the input substrate 8 and the liquid crystal panel electrode 4' to the IC 5 before packaging the IC 5. High reliability is thus obtd.

Title: Device for controlling the number of rain-water pumps
Inventor: OZAKI EMI
IPC: E03B3/02
Filed: 1988-03-28
Abstract: PURPOSE:To suppress the start/stop of an unnecessary pump and to allow rain- water pumps to safely correspond even to the sudden increment of an inflow rate by controlling the number of pumps in consideration of an inflow rate estimate even in a transient period turning a pump discharge valve from its slightly opened state to a fully opened state. CONSTITUTION:When a rain-water pump well level is raised during the running of (n-1) pumps and the level exceeds a n-th pump starting level, a start command is outputted to the n-th pump. Simultaneously the inflow rate is estimated from water level variation per unit time and the cross section of a pump well W. When the n-th pump P is run, the discharge valve V is slightly opened, the level of the pump well W is raised up to the full open of the discharge valve V, and the level exceeds the starting level of the (n+1)th pump, the estimated inflow rate is compared with the maximum discharge flow rate at the time of additionally starting the (n+1)th pump to determine the validity of the output of a start command. When the water level exceeds the starting level of the (n+1)th pump after fully opening the discharge valve V, a start command is outputted at that time to run the (n+1)th pump.
