IPC: G02B7/02
Filed: 1992-04-30
Abstract: PURPOSE:To provide a convenient overhead projector whose initial installation can be easily performed and whose operability is excellent. CONSTITUTION:The reflection angle of a reflection mirror 17 is adjusted so that the projected image of a transparency 15 may fall into the space of a screen 18 and light refracted by a projection lens 16 may be converted in a prescribed direction.

Title: Plating method
Inventor: KATO HIDESUMI
IPC: C25D7/04
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To improve productivity and to reduce a production cost by executing electroplating at a specific current density and passing a plating liquid of a nickel/nickel alloy dispersed with SiC particles at a specific velocity to an object. SOLUTION: This plating apparatus arranges an insoluble anode 4 in an engine cylinder 1. The anode is formed by applying a platinum plating on a titanium material. The plating liquid passes between the cylinder 1 and the anode 4 from an inflow port 2a and emerges from an outflow port 3. Energization is executed between the cylinder 1 and the anode 4. The plating is executed at the current density >=80 A/dm<2> at this time. The plating liquid is a plating liquid of the Ni or Ni alloy dispersed with the SiC particles. The liquid is passed to the object at the velocity of >=100 cm/sec, by which the composite plating film uniformly dispersed with the SiC particles of <=3 μm in the Ni or Ni alloy film is formed on the object. As a result, the eutectoid of the SiC particles having the large grain size is prevented and the plating time is shortened under the large current density.

Abstract: PURPOSE:To avoid malfunctions and let the abnormality of the device be displayed as well by providing a first photo detector on the optical axis of light emitting part and a second photo detector out of the optical axis, detecting the signals of both differentially to detect smoke and lighting a display lamp with the input to the first photo detector. CONSTITUTION:A first photo detector 2 is provided on the axis of a light emitting part 1 and a second light emitting element 3 is provided with a deviation by an angle theta from the optical axis and these are so disposed that only the element 2 receives light when there is no smoke and the element 3 receives the scattering light owing to smoke when the smoke has evolved. The output of the element 3 and the output of the element 2 having been amplified 8 are removed of the effect of interior lighting through filter parts 9, 9' respectively, after which these are applied to a differential amplifier 10 to obtain the input difference of both, which triggers an alarm device 5 when there is the input of more than specified scattering light. When an obstruction such as insect other than smoke has existed in the detector, the output from the element 2 is so small that the display lamp 4 does not go on, indicating the abnormal state of the detector. Here, the alarm device 5 does not actuate either.

Title: White point defect correcting method for image display device
Inventor: IKEGAMI SHUJI
IPC: G02F1/1335
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To easily and rationally make a white point defect inconspicuous by reducing the light transmittance of the portion of the light transmitting film corresponding to a white point defect pixel. SOLUTION: An active matrix liquid crystal display panel has the cell construction in which a liquid crystal layer 3 is held between glass base plates 1 and 2 and a switching element 4a is provided for each pixel 4. The panel displays a picture by varying the transmission of an incident light 8 for every pixel through the on.off control of the element 4a of each pixel 4. If a pixel 5 having the switching element, whose characteristics are degraded, exists, the transmittance of incident light is not varied at the pixel 5 and a white point defect is produced by always showing a white display. Thus, a light transmitting film 6 is pasted on the surface of the plate 2 and a portion 7 of the film corresponding to the white point defect pixel 5 is heated and the transmittance is reduced by making the portion 7 black. Thus, the white point defect is made inconspicuous.

Abstract: PURPOSE: To efficiently obtain mechanical energy, by using a prescribed working fluid for an Otto cycle engine having a cooling jacket for the cylinder of the engine and a cooling jacket for its exhaust pipe and a Rankine cycle engine having an output shaft.  
     CONSTITUTION: A working fluid supplied from a pump 1 into a cooling jacket 3 absorbs heat from a cylinder 4 so that the fluid is evaporated. The evaporated fluid absorbs heat from an exhaust pipe 7 so that the temperature and pressure of the  fluid are heightened to actuate a Rankine cycle engine having an output shaft B.  Rotatory energy is thus obtained. The fluid having finished working is cooled and  liquefied by a condenser 9. Methyl alcohol mixed with a small amount of ammonia  and water, ethyl ether mixed with a small amount of methyl alcohol and water,  aqueous ammonia or the like is used as the working fluid. The cooling and exhaust  losses of an internal combustion engine can thus be changed into effective mechanical energy.
