Title: A/d converter circuit provided with dither noise generating circuit
Inventor: WAKAI TAKUSANE
IPC: H04N5/66
Filed: 1984-04-04
Abstract: PURPOSE:To relax pseudo profile between gradations of a display pattern without increasing bit number of an A/D converter by fluctuating a DC bias voltage superimposed on an input signal in a frequency synchronizing with a frame frequency so as to change information near a threshold value of each comparator by one gradation. CONSTITUTION:A bias voltage generating circuit 2 and a switch 4 consist of MOS-FETs. FET21, 23 are load transistors (TRs), a DC voltage generated from a reference voltage source 25 is inputted to the gate, an FET24 acts like a switching gate and the gate voltage of the FET24 controls the synthesized current value flowing to load TRs. When an input voltage level Vgamma is in the relation of Vc1<Vgamma<Vc2, it is taken the i-th gradation and when Vc2<Vgamma<Vc3, it is taken as the (i+1)th gradation and when Vc3<Vgamma, it is taken as the (i+2)th gradation. In Fig. (f), the picture element corresponding to the t1 of the 1st frame represents the i-th gradation and the picture element corresponding to t'1 represents the (i+1)th gradation because the input DC bias voltage is increased by DELTAh/2V at the 2nd frame and the 3rd frame represents again the i-th gradation and times t2, t'2 are repeated similarly.

Title: Voice coil type linear motor
Inventor: SATOU YOSHIHIKO
IPC: H02K33/18
Filed: 1978-06-05
Abstract: PURPOSE: To generate a damping force with a simple constitution by sealing viscous fluid within a center hole of a center pole to slide a movable rod slider.  
     CONSTITUTION: When a driving current is applied to a voice coil 6, a movable rod 5A mounted on a voice coil installation plane 8B and a movable rod slider 5B perform a linear motion to an arrow mark D2 direction. At this time viscous fluid 4C sealed within a center hole flows to an oppisite D1 direction to a moving direction through a gap 7. Accordingly a viscous force proportional to a speed of a linear motion towards to D1 direction is generated to a movable rod slider and a dmaping force is occurred by this. By doing in this manner, a damping force is generated with a simple constitution not necessitating a linear type tachogenerator or a differentiating circuit etc. and a tracing accuracy of a control system when used for a magnetic head location etc. can be raised.

Filed: 1984-04-05
Abstract: PURPOSE:To inspect the peeling state of paint, etc., without destruction by heating a sticking body such as paint by a heat generating body (e.g. infrared rays) and detecting the temperature of the sticking body. CONSTITUTION:A point film 21 is heated by the heating body, for example, with infrared rays 50 and the temperature of the film 21 is detected by a temperature sensor 60, whose output is inputted to a discrimination means 70. Further, the device is provided with an arm 81, which is moved while held at specific distance from the film 21. Then if the film 21 has a peeling part 22, there is a gap at the peeling part 22, so heat insulation by air is obtained and its temperature is higher than that of other contacting parts. Further, a discrimination means 70 compares the detected temperature with specific set temperature and displays a warning when the temperature rises. Thus, the film is heated by the heating body to easily detect the state of peeling from the film, tiled wall, etc., without destruction.

Title: Dropout detecting circuit
Inventor: TAKEDA KATSUMI
IPC: H04N5/94
Filed: 1981-05-08
Abstract: PURPOSE:To attain detection even for the dropout exsisting in a range from a sink chip to a white peak, by detecting the difference signal between the video signal preceding by a scan period and the present video signal. CONSTITUTION:An input FM signal 1 is demodulated through an FM demodulating circuit 7 and applied to a low pass filter 8. The output passed through the filter 8 is applied directly to a minus input terminal of a differential amplifier 11, and at the same time the output is applied to a plus input terminal via a minus horizontal scan period delaying circuit 10. The output 12 of the amplifier 11 is shaped by a pulse shaping circuit 5 to obtain a dropout detection pulse 6. The degree of correlation is high between the demodulated video signal and the video signal preceding by a scan period, and both video signals have substantially an equal waveform excepting for the dropout period. When a dropout arises, the amplifier 11 delivers the positive pulse, and this positive pulse is shaped to obtain a dropout detection pulse.

Title: Operating device for electronic device
Inventor: HASHIZUME SHOICHI
IPC: H01C10/14
Filed: 1988-03-22
Abstract: PURPOSE:To prevent damage to a stopper or a gear even if an operating dial is turned by main force by devising a gear for a variable resistor such that the gear is driven idle while being slipped at a low tooth height part of a follower gear even if the follower gear in interlocking with the operating dial is stopped by the stopper. CONSTITUTION:Taking the position of a pointer 9 shown in figure as a start, the drive gear 4 meshes with the low tooth height part 11. Even if the operating dial 3 is turned counter clockwise in this state, the stopper 18 is in contact with the projection on a case 1 and does not drive the variable resistor gear 5 further more. The gear 4 incorporated with the dial 3 overrides the gear of the low tooth height part 12 of the gear 5 and is turned idle and then no excessive force is exerted to the stopper 18. When the gear 4 overrides the low tooth height part 12 the low tooth height parts 12 are pressed by the drive of the gear 4 counter clockwise and bent toward a throughhole 16 with a slit 14 inbetween. With the dial 3 driven clockwise conversely, the gear 5 is driven counter clockwise by the gear 4 and the tuning is attained.
