Title: Focusing optical device for single-lens reflex camera
Inventor: FUJII KIYOSHI
IPC: G02B7/28
Filed: 1978-10-09
Abstract: PURPOSE: To prevent the entry of undesired external light by disposing a micro- mirror between the photographing lens and quick return mirror and leading the light reflected by the micro-mirror to a distance measuring photo detector after letting the same be reflected by the quick return mirror.  
     CONSTITUTION: The photographing luminous flux from a photographing lens 21 is reflected by a quick return mirror 22 of total reflection surface and is led to the finder optical system. Part of this photographing luminous flux is reflected by the micro-mirror 25 disposed immediately before the quick return mirror and is further reflected at least once by the quick return mirror 22, after which it is led as a distance measuring luminous flux to a photo detector. Hence, there is no need for forming half-mirror portions to the quick return mirror 22 and mounting plate-form reflecting mirrors and the entry of undesired external light at the photographing may be effectively prevented.

Title: Direct transmission system of picture
Inventor: SAKAI JIYUNICHI
IPC: H04B10/2587
Filed: 1983-07-11
Abstract: PURPOSE:To transmit directly the picture information between two optional points even with a single transmission line with no phase distortion, by transmitting the reference signal for compensation of phase distortions of the transmission line in the time intervals of a picture signal and using the reference signal to compensate the phase information of the picture signal after transmission. CONSTITUTION:A transmission part produces a pulse train where a reference signal is held between picture signals and repeated periodically. This pulse train is sent to a transmission line 19. A reception side separates the output signal sent from the line 19 into two lines 22 and 23 in terms of space. Then a relative delay 25 is generated between the lines 22 and 23 to obtain the coincidence between the arriving times of the output picture and output reference signals by means of a signal matching means. Thus the coincidence is obtained between both signals in terms of time, and these signals are made incident to a phase distortion compensating part 27 to offset the phase distortions during transmission along the transmission line. Thus it is possible to compensate the phase signal in the transmission line at the reception terminal. Then the 2-dimensional picture information can be transmitted directly between two optional points.

Title: Image reader, image processing system, operation control method and storage medium
Inventor: SAKAI TAKASHI
IPC: H04N1/21
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To obtain an image reader that surely outputs image information read from an original in an excellent state externally. SOLUTION: In the case of controlling stop and restart of original scanning by a read means 120 on the basis of an idle capacity of a storage means, a time interval from stop to restart of the read means 120 is reserved at least for a prescribed time. Thus, even when the read means 120 is stopped due to a deficient idle capacity of the storage means and vibration takes place, since the image reading is not started until the vibration is restored, the image information read from an original is not affected by vibration of the read means (disturbed image or the like).

Filed: 1990-05-15
Abstract: PURPOSE:To securely and highly accurately measure an absolute pressure in any measurement environments by providing an air hole on a sealed case and housing a sponge body in the case to detect a change in pressures. CONSTITUTION:A fine air hole 2 of approximately 0.1mm is provided on a wall surface of a rigid sealed case 1, and a speaker 3 and a capacitor microphone 4 are placed on an opposite position inside the case 1. The air hole 2 gives flow resistance to air so that a fluctuation in pressure due to sound pressure and wind pressure generated outside the case 1 may not enter inside without attenuation. Then, a space in front of the speaker 3 is filled with a sponge body 5 such as a sponge to attenuate the sound pressure and the wind pressure generated outside the case 1 and also causes an isothermal change when the air is compressed by the speaker 3. Thus air admittance to and/or exit from a space formed between the microphone 4 and the speaker 3 is limited to prevent a change in gas conditions such as humidity and temperature, so that a static fluctuation in pressure outside the case 1 can be accurately detected while occurrence in measurement errors and entrance of dust, etc. can be prevented.
