Title: Projection type display device
Inventor: SATO KAZUTO
IPC: G03B21/10
Filed: 1999-12-07
Abstract: PROBLEM TO BE SOLVED: To improve a situation that a video can not be projected on plural screens with appropriate brightness for many persons by one projection device because one screen is prepared for one projection device in the conventional manner. SOLUTION: Video light radiated from a projector 10 is partially reflected by the screen 1 having such characteristic that 50%s of light is transmitted and 50% thereof is reflected, and the rest of the video light is transmitted and displayed as the video. The reflected light reflected by the screen 1 is made incident on and totally reflected from reflection device 2, and made incident and totally reflected from a reflection device 3 after its optical path is changed. Then, the reflected light is made incident on the screen 4 arranged in parallel with the screen 1 after its optical path is changed again. The reflection device 2 has curved structure so that the incident video light is made incident on the screen 4 after it is inverted right and left.  Thus, the same video is simultaneously displayed on two screens 1 and 4 without being inverted up and down and right and left by one projection device.

Abstract: PURPOSE:To perform photographing in an aperture-priority mode by using an IG meter by controlling current amount according to the detection output of the diameter of the opening of an aperture means controlling the diameter of the opening of an aperture based on a current. CONSTITUTION:In the case of the aperture-priority mode AP, the diameter of the opening of a stop blade 3 is fixed, and adequate exposure is obtained by feeding back the brightness 10a of an image plane to an accumulation time controlling circuit ATC by an SW3. Thus, the SW10 supplies a signal 10c obtained by converting the signal 10b detected by a hole element 55 as a feedback signal 10e to the aperture diameter of the opening at a CPU 9, and the CPU 9 supplies a signal 10f expressing the aperture diameter of the opening set at a manual aperture setting circuit AS as a reference signal 10d to an aperture driving circuit 6. The feedback signal 10e is compared with the reference signal 10d by a comparator at the aperture driving circuit, and a value obtained by multiplying the difference by a specified factor by an amplifier is added to the current flowing in a present driving coil. Consequently, the aperture diameter of the opening is always fed back so as to approach the set diameter of the opening.

Title: Data processor
Inventor: IKEDA KOICHI
IPC: G06F13/362
Filed: 1991-12-10
Abstract: PURPOSE:To synchronize the set of a busy signal with a data transmission from a host by outputting the busy signal synchronously with a strobe signal transmitted from the host. CONSTITUTION:A signal 4A is set to be H by an MPU at the time of the on-line of a storage device, or at the time of an error such as the absence of paper. The BUSY signal is not turned to H even when the signal 4A is H, and a data transfer can be attained by the host. When the data are transferred from the host, the BUSY signal of the Q output of an FF 400 is turned to H by a STROBE signal. Thus, the BUSY state set by the MPU can be synchronized with the STROBE signal.

Inventor: TERAGUCHI MIKIYA
IPC: G01B21/00
Filed: 1999-12-09
Abstract: PROBLEM TO BE SOLVED: To provide a displacement detector capable of eliminating the influence of the heat by a heating element to perform a precise measurement even when one of a fixed part and a movable table subjected to mounting constitutes the heating element. SOLUTION: This linear encoder 10 detects the linear displacement of the movable table 2 reciprocating to a fixed part 1 mounted on a drive unit constituting the heating element. This encoder 10 comprises a body 11 to be mounted on the fixed part 11 and a detector 12 to be mounted on the movable table 2. Since the body 11 has a groove part 13A on the outer surface, the heat of the fixed part 1 is released to the outside through the groove part 13A even if the fixed part 1 generates heat. Therefore, this heat is never transmitted to the inner part of the body 11.
