Title: Strobe tuning device
Inventor: KITAGAWA MASAHIRO
IPC: G06F9/48
Filed: 1980-07-31
Abstract: PURPOSE:To prevent the erroneous photographing owing to malfunction when a strobe device other than an exclusive auto strobe device is mounted by making a flash emitting thyristor conductable only when the mounting of the exclusive strobe device is detected. CONSTITUTION:When a strobe device other than an exclusive auto strobe device is mounted to a camera, a detecting circuit 94 is not energized, and a transistor 98 is nonconducting. Therefore, when auto mode is set by opening a changeover switch 80, the output end of a NAND 90 goes to a high level via a NAND gate 86, and a thyristor 108 for emission of a flash tube does not conduct, thus ordinary photographing by natural light is carried out and the erroneous photographing owing to a  tuning miss of the strobe and the shutter is prevented. If in this case a prescribed  time such as 1/60 second is set, an FF2 is reset via a counter 18, and the output of  the gate 90 inverts, whereby flash photography is accomplished.

Title: Sight-line following video display device
Inventor: OSADA HIDEKI
IPC: G09G3/20
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To display a video without the sense of incompatibility without requiring complicated control by making the luminance of a high definition video on a projection plane into the specified multiple of the luminance of a wide view field video. SOLUTION: A control means 41 takes a video signal out of an external video source 47, applies a wide view field video signal to a means 44 for wide view filed display and applies a high definition video signal to a display means 43 for high definition display. At the same time, the control means 41 controls display position adjusting means 42 so as to display the high definition video at the sight-line position of an observer based on the detected result of a sight- line information detecting means 40. Then, the control means 41 controls the light emission intensity of two display means 43 and 44 so that the luminance of the high definition video on the projection plane can be the 0.1 to 0.9 multiple of the luminance of the wide view field video.  Thus, by reducing the luminance of the high definition video rather than that of the wide view field video, the luminance at the concerned part of the observer can be prevented from being extremely increased.

Abstract: PURPOSE:To make it possible to perform automatic initial setting and calibration of a clock circuit at the time of navigation data by using the time of the navigation data as control signals with respect to the time. CONSTITUTION:At first, the signal of an artificial satellite is picked up so as to start position measurement. Thereafter, navigation data are collected. The time at a position measuring place, e.g. the Japan standard time including date, is computed. Then, the time difference D between the Japan standard time and the time of a clock circuit 10 is obtained. Thereafter, time difference is longer than, e.g. 10 seconds or not. In this way, the time of the navigation data is used as a control signal for the time. When the time difference D between the time of the navigation data and the time of the circuit 10 exceeds the specified value, the time of the circuit 10 is automatically calibrated. Then, the time (set date and time) inputted from an operating part 1 and a message are stored in a RAM 9. The time difference T between the inputted time and the time of the circuit 10 is obtained. It is judged as to whether the time difference T becomes 0 or not. When the time difference T is 0, a buzzer 21 is sounded and the message is displayed on a CRT display 5 for a specified time.

Abstract: PURPOSE: To obtain an excellent target for the formation of an oxide thin film having a (Ba,Sr)Ti perovskite structure by oxidizing and reducing a Ba-Sr- Ti oxide powder and sintering the powder in a vacuum hot press. CONSTITUTION: A Ba-Ti oxide powder and a Sr-Ti oxide powder or (Ba,Sr)Ti oxide powder, each prepared by a sol-gel processing and having 1-10μm average particle size, are used as the source material and oxidized in an oxidative atmosphere such as air at 700-1200 deg.C to decrease the carbon content to <=1000ppm and the oxygen content to the amt. corresponding to the stoichiometric value. Then the source material is reduced by heating at 450-1300 deg.C in a hydrogen atmosphere to decrease the carbon content to <=100ppm and the oxygen content to less than the stoichiometric value. Then the source material is hot-pressed in vacuum to obtain a sintered body having <=30ppm carbon content. Thus, a sputtering target for the formation of a thin oxide thin film having a (Ba, Sr)Ti perovskite structure is produced as the sintered body above described.  The obtd. target has excellent toughness and little carbon content.

Filed: 1993-05-07
Abstract: PURPOSE:To improve operability by performing the display of a special character only when it is needed and performing alternate display when it is not needed by providing a display control means for displaying the special character in place of a form enabling high-speed display. CONSTITUTION:Corresponding to the designation of a document input mode, a CPU 11 alternately displays a graphic character on a document input picture in place of the form enabling the high-speed display based on information (such as the kind, size and coordinate position of the character or the like) stored in a graphic area 13b of a RAM 13. On the other hand, corresponding to the designation of a graphic input mode, the CPU 11 sets the display mode of the graphic character and normally displays the graphic character on a graphic character input picture. Since the graphic character is normally displayed only when the display is required but the alternate display is performed when it is not required, time required for displaying the graphic character can be considerably shortened when the enlargement/reduction processing of the graphic character is realized only by software logic, and operability can be improved.
