Title: Display device
Inventor: HATANAKA HIROYUKI
IPC: G02B27/02
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To form a virtual image to be observed without distortion by using an optical system having an optional optical characteristic by providing a device with a means distorting a picture displayed on a picture display surface from a display objective picture so that the distortion of the virtual image from the display objective picture caused by the optical characteristic of the optical system is canceled. SOLUTION: When image data is outputted to a display unit 3, the picture is displayed on the picture display surface 3a and picture displaying light L corresponding to the displayed picture is emitted. The picture displayed on the display surface 3a is distorted from the display objective picture so as to cancel the distortion of the virtual image from the display objective picture caused by the optical characteristic of the optical system 2. That means, the virtual image to be observed is distorted from the picture displayed on the display surface 3a caused by the optical characteristic of the optical system 2.  Thus, since the distortion of the picture displayed on the display surface 3a and distorted from the display objective picture is canceled by the distortion caused by the optical characteristic of the optical system 2, the display virtual image without distortion being coincident with the display objective picture is obtained.

Title: Base station selection system
Inventor: KOO HIDEO
IPC: H04W24/10
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To surely select a base station of a zone, where a mobile station exists by comparing the reception electrolytic level of the base station with the reception level of the mobile station for selection of an optimum base station. SOLUTION: When a mobile station 12 performs transmission to call out a command console 1, the console 1 responds. Then, a base station 9-2 performs transmission, and a receiving level signal output circuit 14 of a mobile station 12 measures the receiving electrolyte. Next, when the station 12 responds, a switch 15 operates before the calling and transmits a receiving level in a short time. The signal is received at a mobile station receiving level decision circuit 7 of a controller 2 and is compared with a prescribed level at a control station 8. If the signal level is lower than the prescribed level, a transmission control circuit 3 is controlled to switch the transmitting base station. Since the station 12 is moving, its level is changes all the time.  Thus, it is possible to select an optimum base station by monitoring the receiving levels of both stations 9-2 and 12 with the controller 2.

Abstract: PURPOSE:To reduce leak checking operation by applying differential pressure while an on-off value to be inspected is closed, deciding whether variation in the pressure in a manifold with time exceeds a previously set permissible value or not from a sensor output, and annunciating whether there is a leak or not. CONSTITUTION:All solenoid on-off valves except solenoid on-off valves H and N are opened to evacuate a system by a vacuum pump 5, and it is considered that there is a leak in the piping system unless the degree of vacuum sttains to a specific value within a specific time. When there is no leak, a severer check is made on the basis of whether the difference between the pressure right after a solenoid on-off valve VAC and the pressure after a specific time is within a permissible value range or not. Further, the valve H is opened in the state where the valves H and N are closed and other valves are opened to admit helium gas into all systems and the valve H is closed when the pressure exceeds 760mmHg. Then, the valve E to be checked is closed and evacuation is carried out by the pump 4; and it is considered that the valve E is normal unless the pressure in the manifold 1 attains to the permissible pressure within a specific value, and valves PS, S1-S3 are checked by the same procedure.

The base material 7 is crimped by the rollers 6a, 6b and the dry films 3 are transferred under heating to both surfaces of the base material 7. The base material 7, with both surfaces of which the films 3 are brought into pressurized contact is transported as the substrate 10 for exposing toward the transporting rollers 6c, 6d. A transporting roller 15 and a transporting roller 11 begin to rotate when the substrate is crimped between the rollers 6c and 6d. The cooler 19 operates simultaneously with the rotation of the roller 11 and air is blown to the films 3 on the surfaces of the substrate 10 discharged from an ejection port 13, by which the heat of the substrate 10 is radiated. The films 3, 3 brought into pressurized contact with both surfaces of the base material 7 are cured in this way and the advance of the film 3 into the through-hole opened in the base material 7 is prevented.

Title: Optical recording medium and its manufacture
Inventor: UENO OSAMU
IPC: G11B7/24097
Filed: 1988-08-17
Abstract: PURPOSE:To realize high-speed access on tracks without causing access errors by providing several nonrecording parts having low reflectivity disposed with intervals in the recording layer. CONSTITUTION:The optical recording medium 1 essentially consists of a disk- type glass substrate 3 the surface of which has concentrical rough areas 2, the recording layer 4 uniformly provided on the substrate, and a protective layer 5 uniformly provided on the recording layer 4 side of the substrate 3. The recording layer contains nonrecording parts 6 formed on rough surface parts 2' of the rough areas 2 and recording parts 7 formed on the flat area 2'' provided between the rough areas 2. As the intensity of reflected light from the nonrecording part 6 is weak compared to that of reflected light from the recording part 7 between the nonrecording parts 6, difference between the two reflected lights becomes large. Therefore, only the track-crossing signals with low output generated when a head crosses the nonrecording part 6 can be certainly extracted according to the difference of reflected lights. Thus, the access speed on tracks can be raised.
