Title: Automatic focusing camera
Inventor: KAKITA TAKESHI
IPC: G03B17/56
Filed: 1989-10-16
Abstract: PURPOSE:To accurately execute rang-finding and to surely prevent middle omission by providing horizontally osillating mechanism which rotates a camera by a desired angle on a horizontal plane and performing multipoint range-finding while rotating the camera from right to left by means of the mechanism. CONSTITUTION:The oscillating mechanism is housed in the recessed part 100a on the bottom part of a camera main body 100. The swinging mechanism is provided with a driver 34 for controlling a horizontal rotation motor 30a and a driver 35 for controlling a vertical rotation motor 30b. The position of horizon tal rotation is detected by photointerrupters 38 and 39 and the position of verti cal rotation is detected by photointerrupters 42 and 43. Since a pulse signal is outputted fromt he photointerrupters 38 every time the camera is rotated once, a microcomputer confirms the rise and fall of the pulse signal and performs the range-finding by having infrared light emitted from an infrared LED. Thus, the range-finding is performed within the range which is 20 degrees right and left by taking the position of the camera as a center every time the camera is rotated, and 41 range-finding data are totally obtained. Thus, the multipoint range-finding is executed by one infrared light emitting element.

Inventor: SASAKI SUSUMU
IPC: H04J3/06
Filed: 1985-11-29
Abstract: PURPOSE:To attain the effective initial control for many slave stations by designating the slave station to apply initialization through a master station. CONSTITUTION:An initial setting part 10 is shown in an area enclosed by a broken line and includes a separating circuit 11 which separates a time slot related to the initialization, i.e., the discrimination code ID contained in a common signal time band T0 and a time slot for phase transmission P from the output of a synchronization fixing circuit 1, an initial synchronization fixing circuit 12, a distance difference detecting circuit 13 and a switch 14. When the clock signal is received from a master station, the initialization burst is sent to the master station based on the delay times of a delay time correcting circuit 3 and a delay circuit 4 or the delay time obtained by adding an integer multiple time of a single frame period T to the delay times of both circuits 3 and 4. While the master station checks the phase of said burst in the same way as a conventional technique and transmits an error if detected in the time slot for transmission of phase.

IPC: H01J37/317
Filed: 1988-10-25
Abstract: PURPOSE:To reduce the chromatic aberration effect of a convergent lens by correcting the magnetic field of the convergent lens corresponding to a ripple variation of an acceleration voltage. CONSTITUTION:Assuming that, for example, an acceleration voltage changes by DELTAE and increases that much, a ripple detector 6 detects such an increase DELTAE and an exciting current is supplied to an auxiliary coil 12 such that a magnetic field increases by DELTAB.

Even in this case, a beam is converged to the same optimum position in spite of variation of the acceleration voltage. Thereby, it is possible to reduce the chromatic aberration effect of the conversion lens.

IPC: B01D59/26
Filed: 1985-12-02
Abstract: PURPOSE:To enhance not only energy efficiency but also economical efficiency, by filling a container with a sublimable gas at ambient temp. without adding a heat cycle. CONSTITUTION:Sublimable gas, example, UF6-gas is supplied to a compressor 1 from a gas introducing pipe 11 to be pressurized to several 100Torr and continuously transferred to a container 6 held under room temp. to be collected on the inner wall surface of the container 1 as a solid. Whereupon, HF-gas having b.p. of 19.5 deg.C and vapor pressure about 60 times larger than that of UF6 is generated to be accumulated in a gaseous phase and, because the pressure in the container 1 increases during operation, the UF6-gas is transferred to a container 7 at the point of time when the pressure in the container 1 is several 100Torr and the same operation as mentioned above is performed. During this time, the gas in then container is introduced into a separator 9 filled with an adsorbent by a vacuum pump 5 to catch HF in the pores of the adsorbent. The UF6-gas flowing out from the separator 9 is returned to the gas introducing pipe 11 to be treated. When the pressure in the container reached about several 10Torr, gas withdrawing operation is finished.

Title: Output buffer circuit
Inventor: CHO SHIZUO
IPC: H03K17/16
Filed: 1994-11-02
Abstract: PURPOSE: To reduce the timewise change rate of a current value by controlling the gate potentials of respective first P-MOSFET and first N-MOSFET of driving transistors with a potential at the output terminal of the output buffer circuit. CONSTITUTION: When an input signal IN is changed from 'H' to 'L' during a term t3, the output of a first inverter 21 is transited from 'L' to 'H' so that a first MOSFET 25 can be turned to an OFF state. Besides, since the level of an output terminal OUT is still set at the 'H' level during the term t3, a second MOSFET 33 is set in the OFF state as well. Therefore, since a power source flows through the path of power source VDD → 5th P-MOSFET 23a → 2nd N-MOSFET 33 → 3rd NMOSFET 35, the potential of a node 23x is transited from the 'L' to an intermediate level. Besides, since the respective gates of the FET 35 and the 1st N-MOSFET 27 are mutually connected, a current flows to the FET 27 and with this current, the level of the terminal OUT is gradually pulled down.
