The mounting member holder is attached to an electronic parts mounter. The set of electronic parts is mounted on the printed circuit board at once by the mounter.
Abstract:
A VIDEO DISPLAY APPARATUS COMPRISING A VIDEO DISPLAY DEVICE FOR VISUALLY PRESENTING A VIDEO IMAGE THEREON ; A LIGHT SOURCE TURNED ON BY DISCHARGE AND DISPLAYING THE VIDEO IMAGE, WHICH IS BEING PRESENTED VISUALLY ON THE VIDEO DISPLAY DEVICE, ON A SCREEN BY IRRADIATION OF LIGHT; AND A SYSTEM CONTROLLER FOR PUTTING OUT THE LIGHT SOURCE AFTER A LAPSE OF A PREDETERMINED DELAY TIME FROM INPUT OF A COMMAND TO SWITCH OFF A POWER SOURCE. THERE IS ALSO PROVIDED A METHOD OF PREVENTING INADVERTENT SWITCH- OFF OF THE LIGTH SOURCE IN SUCH A VIDEO DISPLAY APPARATUS. EVEN IF THE POWER SOURCE IS SWITCHED OFF INADVERTENTLY, THE LIGHT SOURCE IS NOT PUT OUT AT ONCE AND THE VIDEO IMAGE CAN STILL BE DISPLAYED CONTINUOUSLY THEREON BY SWITCHING ON A POWER KEY IMMEDIATELY WITHIN THE PREDETERMINED DELAY TIME.

PROBLEM TO BE SOLVED: To assure mounting of a chip by providing an adjustment mechanism which, fitted for axial movement, absorbs the difference in height of entire chip for each stick between a pusher rod and a drive means to move it. SOLUTION: Using an air cylinder device 8 for a drive source of a drive means 7, a pusher rod 6 is supported upright at a push-up plate 9 fitted to the tip end of a piston axis 8a of the air cylinder device 8. An adjustment mechanism 15 is provided between the pusher rod 6 and the push-up plate 9 of the drive means 7 which moves the pusher rod 6. The adjustment mechanism 15 is fitted with the pusher rod 6 for axial movement with a required friction against the push-up plate 9 of the drive means 7. Thus, sure mounting operation for a chip part is provided.

PROBLEM TO BE SOLVED: To obtain a method and device for aligning chip components which can align leadless chip components having the orientation of polarity, etc., fore and aft by means of a simple mechanism. SOLUTION: Leadless chip components 4 fed from a feed path are held in one 3a of recesses provided at 90 deg. intervals along the periphery of a rotor 1 which rotates round the Z axis, and a sensor 6 discriminates the fore-and-aft orientation of the chip component 4 within the recess 3a, and when the chip component 4 is oriented forward, the rotor is rotated clockwise by 90 deg., and the chip component is carried out of the recess 3d through a path 5 by means of the discharge pressure of air while the chip component is kept oriented forward. When the chip component 4 housed in the recess 3a of the rotor 1 is oriented backward, the rotor 1 is rotated counterclockwise by 90 deg., and the chip component 4 is oriented reversely and carried out of the recess 3d. A device for aligning which neatly aligns the fore-and-aft orientation of leadless chip components is provided.

PROBLEM TO BE SOLVED: To make enjoyable viewing a video continuously by turning on a power source key immediately even when a power source is inadvertently turned off, by controlling to stop the lighting of a light source when the delay time has elapsed after designating the turning-off of the power source. SOLUTION: By depressing the power source key of a remote controller, a reception part receives a fact that the power source key has been depressed and a control part recognizes that the power source is turned off (S1). Thus, the control part transmits a signal to an audio control device so as to mute a sound from a speaker and transmits the signal to a picture display IC so as to mute a picture (S2). Then, the control part stops the supply of a lamp lighting signal LS to the power source PS after waiting for the specified delay time, for example, five seconds (S3). Thus, the lamp is turned off (S4). When a user turns off the power source because he goes to bed or he goes out, picture muting and sound muting are performed and then the light emission of the lamp is stopped after the delay time has elapsed.
Abstract:
PROBLEM TO BE SOLVED: To mount a plurality of chip type electronic parts on a printed wiring board at the same time, by arranging the constitution such that an adhesive is applied in the specified position of a printed wiring board by bringing a needle where an adhesive adheres into contact with the printed wiring board supported by a supporting member. SOLUTION: When the press board 31 is arranged in the press position, a needle mounted on a top plate 33 is inserted into the adhesive within a adhesive storage grove 13a. Then, in condition that the press board 31 is returned to the waiting position from the press position, an adhesive is mounted on the needle of the top plate 33. Then, a base plate 13 is slid right and is arranged in the adhesive application position, and the press board 31 is fallen down from the waiting position to the press position. Until the top end of the press board 31 abuts on the stopper, the press board 31 is pivoted. Thereby, the tip of the needle abuts on the printed board 50, and the adhesive mounted on the needle is applied to the printed wiring board 50.
Abstract:
PURPOSE: To display an image normally without disturbance by displaying a sub video signal replacing a main video signal when noise is mixed with the main video signal or a non-standard signal is received or in the case of non-signal while two-screen patterns are displayed. CONSTITUTION: When a noise, non-signal and non-standard signal detection section 18 detects mixed noise in a main Y/C signal, a main microcomputer 19 discriminates it that noise is mixed in the main Y/C signal based on a detection signal received from the noise, non-signal and non-standard signal detection section 18. Then in this case, since 2-screen patterns are displayed, the main microcomputer 19 provides an output of a control signal to a changeover switch 13 to allow the switch 13 to replace the main Y/C signal with a sub V signal and it is outputted to a video processor 10 and a PinP, PandP block 11. Simultaneously the main microcomputer 19 replaces the two-screen patterns to be displayed on a CRT 12. Thus, even when an image of the noisy main Y/C signal is disturbed due to noise, an image of the sub V signal is displayed on the screen without disturbance.
Abstract:
PURPOSE: To provide a television receiver outputting a desired sound mode (monoral broadcast, streo broadcast, bilingual broadcast, sound multiplex broadcast, B-mode broadcast and the like) whenever a viewer changes a channel or whenever the sound output screen of two-screens display is changed. CONSTITUTION: Signals inputted from an U/V tuner 3, a CS/BS tuner 4 and an external video input 6 are inputted to a sound mode detection 21. The desired sound mode is selected by the sound mode detection 21, a memory 19 and a main microprocessor 14, and it is outputted to an audio processor 10, AMP 12 and a speaker 13. When the viewer changes the channel and when he switches the sound output screen of multiple picture display, it is not necessary to reset the sound mode, he is released from the trouble of setting, satisfied with a video and sound broadcasted.
Abstract:
PURPOSE:To make a pattern of a video signal at non-signal stable. CONSTITUTION:A video signal selected and received by a tuner 2 is fed to a video output circuit 5 through a switch 4, a signal from the video output circuit 5 is fed to a cathode ray tube 6, on which the signal is displayed, and the video signal from the tuner 2 is fed to a picture memory 7 by, e.g., one frame and an output of the picture memory 7 is fed to the switch 4. Moreover, the video signal from the tuner 2 is fed to a non-signal detection circuit 8, a control signal from the non-signal detection circuit 8 is fed to the picture memory 7 and the switch 4. The switch 4 is switched in the non-signal state of the video signal to output a signal stored in the picture memory 7.
