摘要： PURPOSE:To facilitate the formation of a title image, etc., by specifying starting and finishing positions on a superposing and recording tape with the value of a tape counter and selecting a character, a picture, etc., from a previously prepared image library. CONSTITUTION:The traveling quantity of a tape is calculated in the units of hours, minutes and seconds based on a microprocessor PC 11 or a CTL signal and a reel pulse and the information of a counter is formed. Thus, information as to the starting and finishing positions for superposing and recording a title in image is made into the information of the counter, it is stored in the PC 11 and superposing and recording are started and finished by making the value of the counter at the time of edition coincidnt with the stored one of the counter. A video signal from the outside supplied to synthesic circuits 18 and 19 via an input section 20 and the title image read out from a memory 10 by a titler circuit 9 is synchronized horizontally and vertically with a color phase and inserted as a composite picture.

摘要： PURPOSE:To facilitate editing by providing a program editing function enabling the insertion of a preliminarily prepared title picture and 'Telop(R)' picture from a designated recording starting point into arbitrary positions in an end point. CONSTITUTION:The camcorder consists of a tape drive system 1, pre-amplifier 2, luminance-system video circuit 3, chroma-system video circuit 4, video switch circuits 5 and 6, burst gate circuit 7, synchronizing separator circuit 8, titler circuit 9, digital memory 10, microprocessor 11, operation switch groups 12, CTL circuit 13, and reel pulse circuit 14. At the time of tape dubbing/editing, the recording start and end points are preliminarily stored as counter information (data of time, minutes, and seconds), and the insertion points of the title picture and the picture pattern selection of the title picture can be preliminarily set. Thus, the contents can be easily edited into a satisfactory state.

摘要： PURPOSE:To eliminate need for a level adjustment by allowing a gain control circuit to adjust the gain with a DC voltage in response to a difference of signal levels so that a 1H delay video signal and a video signal not delayed have an equal level. CONSTITUTION:One of input video signals is fed to a one-horizontal period delay circuit 1 and the other is fed to an adder circuit 6. The level of a one- horizontal period delay video signal (1H delay signal) outputted from the one- horizontal period delay circuit 1 is adjusted by a gain control circuit 2 and added to a video signal not delayed at an adder circuit 6. A detection circuit 3 detects the level of the 1H delay signal and a detection circuit 4 detects the level of the signal not delayed. These signals are fed to a comparison amplifier 5, and a level difference signal obtained from the comparison amplifier 5 is fed to the gain control circuit 2. Then the comparison amplifier 5 adjusts the gain so that the level of the not delayed signal and the level of the 1H delay signal are equal to each other in this way. Thus, the adjustment of the addition/subtraction of the not-delayed signal and the 1H delay video signal in a comb-line filter is not required.

摘要： PURPOSE:To increase the mechanical strength after the assembling and to improve the efficiency of finish work of a passage by composing the runner with runner division pieces whose each vane furnishes a part of a crown and a part of a shroud integrally. CONSTITUTION:A runner division piece is formed of numerous vanes 2 integrally in the condition each vane furnishes a part of a crown and a part of a shroud ring 3. And a circular flange 1' and a ring 3' to connect the runner division pieces to the outer surface of the crown 1 and the shroud ring 3 are provided. As a result, there is no restriction to form a necessary joint curving in the connections between the vanes 2, and the crown 1 and the shroud ring 3, and thereby, an ideal mechanical strength of runner can be secured. And since there is no restriction of space for the finish work of the part corresponding to the passage of the runner, the finish work can be carried out easily.

摘要： PURPOSE:To attain image pickup without fail by outputting optionally a reference line in a horizontal direction or a vertical direction in the inside of an electronic view finder. CONSTITUTION:When an unstable pattern is obtained due to a camera not placed horizontally, a horizontal reference line 6 and a vertical reference line 7 are indicated on a screen by the operation of an operating button 1 and the reference line is moved to a position so that an object and the reference line are easily compared. When the horizontal reference line 6 is moved upward and the vertical reference line 7 is moved to the right by the operation of the operation button 1, the camera is placed horizontally by the horizontal reference line 6 and the vertical reference line 7 to obtain a stable pattern. When the camera is laced horizontally and the preparation of the image pickup is finished, if the horizontal reference line 6 and the vertical reference line 7 are not required, the lines are erased from the pattern by the operation of the operation button 1 and the pickup is tried. Thus, the picked-up video without fail is offered to the photographer.

摘要： PURPOSE:To recognize a distance to an object which is actually photographed by detecting the position of a focus ring moved by a motor, deducing the distance to the object which is photographed based on the detected position and displaying the distance. CONSTITUTION:Discrimination and driving circuits actuate an automatic focus motor 4 or the like and rotate the focus ring 5. Then, a lens on the inside is moved and finally brought in a focused state. Outputted information is outputted as the numeric value of the focusing distance previously set by a character generator 8. The image of the object under the focusing state is passed through an image pickup element 9, converted to a video signal by an encoder 10 and inputted to a VTR part 11 as the output of a camera. In the VTR part 11, the information of the distance at a focusing time outputted by the character generation circuit 8 is mixed with the video signal by a video output circuit 12 and outputted as the output of the video. Thus, the focusing distance is displayed on a monitor.

摘要： PURPOSE:To obtain a high-performance circuit breaker of low operating force and low attrition rate by connecting a gas-blast circuit-breaking portion including an arc-driving means in series to a vacuum circuit-breaking portion. CONSTITUTION:A vacuum circuit-breaking portion 1 and a gas-blast circuit- breaking portion 2 are arranged in a tank type vessel 3 wherein sulfur hexafluoride gas of several atmospheric-pressure is sealed. The vacuum circuit- breaking portion 1 has electrodes 7, 8 which are fixed respectively to the top ends of paired conductive robs 5, 6 in a vacuum vessel 4, the conductive rod 5 is fixed airtightly to an end sheet 9 and the conductive rod 6 is sealed airtightly to an end sheet 10 via a bellows so as to rotatable in the axial direction. The gas-blast circuit-breaking portion 2 has a coil 16 installed in a fixed contact 14 out of a contact 13 and the contact 14. When an arc turns to an arc contact 15 at the top end of the coil 16, the coil 16 induces a driving magnetic field in the axial direction to rotate a pillar of the arc. Thus, the vacuum circuit-breaking portion 1 cuts off a current in the domain of a small current while the gas-blast circuit-breaking portion 2 cuts off a current in the domain of a large current.

摘要： PURPOSE:To shorten the time of exchange between the wafer unload after exposure and the load of an unexposed wafer by constituting a carrier arm out of an outer arm, which goes in and out picking up the two opposed sides of a wafer, and an inner arm, which goes in and out picking up the side caught by the two sides or the center. CONSTITUTION:When taking out an unexposed wafer 12a from the pocket at the lowermost stage of a cassette, a cassette 5a is elevated to directly oppose an inner arm 3, and hereafter in the order of arm entry, cassette descent, wafer suction, and arm retreat, the wafer is pulled out being sucked by the inner arm 3. Next, the entire arm 1 is rotated 90 deg. to align orientation flat,and it is opposed directly to a table 6, and in the order of wafer entry, suction release, elevation of a rotary table 7, wafer suction, and arm retreat, the wafer is carried to the table 6. Subsequently, in the order of the descent of the arm 1, the entry of outer arms 2a and 2b, and the descent of the table 7, it is sucked with the outer arms, and the arm 1 is elevated and rotated 90 deg. again, and the wafer is carried onto an exposure stage 9.
