Abstract: PURPOSE:To enable replacing work of a tool with single drive source, by providing a mechanism for driving a pull rod and mounting/dismounting the tool onto/from a spindle, when the spindle is at a position for replacing the tool, while furthermore driving a sliding chip and opening/closing a tool grip mechanism. CONSTITUTION:When a rod 31a of an air-cylinder 31 is extended, an operating lever 32 is rotated to release a fork lever 65. Consequently, a tool clamp mechanism 60 on a spindle MS is clamped so as to mount a tool T being carried onto the axis of the spindle MS onto the spindle MS and clamp. At the same time, a sliding chip 75b of a tool arm 72 is moved through the operating lever 32, a rod 33 and a crank 34. As a result, a claw member 75a in a tool grip mechanism 75 opens to release the tool T. In such a manner, open/close operation of the tool grip mechanism 75 and mount/dismount operation of the tool T onto/from the spindle MS can be carried out simultaneously.

Title: Television broadcasting signal deciding circuit
Inventor: YAMAMOTO KOJI
IPC: H04N5/44
Filed: 1988-08-31
Abstract: PURPOSE:To detect that a broadcast is not executed without fail by detecting that an output level goes to be <= a prescribed value when a tuning frequency is dislocated by the prescribed value even in case that there is or not a synchronizing signal in the video signal of an intermediate frequency in a selected TV channel. CONSTITUTION:A tuner 1 selects the TV channel according to an output signal 50 of a microcomputer 5 for channel selection and the TV channel is converted to the intermediate frequency and inputted to an intermediate frequency processing circuit 2. A video signal 200 is detected and outputted by the intermediate frequency processing circuit 2 and a sound intermediate frequency 100 is outputted. The synchronizing signal in the video signal 200 is detected by a synchronizing signal detecting circuit 4. Then, when the synchronizing signal is not included, it is decided that the broadcast is not executed on the channel. When the video signal is included, the output voltage 50 is changed and the tuning frequency of the tuner 1 is changed by the prescribed value. Then, when it is detected that the output level is lowered to be <=the prescribed value, it is decided that the broadcast is not executed on the channel. Thus, even when the broadcast is executed on the adjacent channel with a strong electric field, the presence or absence of the broadcast on the subject channel is exactly detected.

Filed: 1990-08-15
Abstract: PURPOSE:To hold a surge current due to battery connection below a specified value while using less number of components by a method wherein a resistor for battery charging is used also for control of the surge current. CONSTITUTION:Between a positive terminal 1 of a battery and a load terminal 2 for battery backup, a battery charging/discharging circuit is located which is constituted of a resistor R1 and photo thyristor PSCR1.

Title: Production of color filter
Inventor: ADACHI MASAAKI
IPC: G02F1/1335
Filed: 1987-08-28
Abstract: PURPOSE:To improve the contrast of a liquid crystal display panel by printing plural color inks on a base material to form respective color element layers at prescribed intervals and projecting a laser beam to the projecting parts of the film thickness of the respective color element layers, thereby drying and curing the plural color inks. CONSTITUTION:The surface 6a of the color element layer 6 made of the liquid red ink formed in a printing stage is formed with waving having the projecting parts 6b and recesses 6c and the film thickness of the color element layer is not uniform. The liquid inks in the projecting parts 6b are then heated to have the increased temp. and decreased surface tension when the laser beam is projected to the projecting parts 6b from a fiber 12. A difference in the surface tension is, therefore, generated between the liquid inks of the recesses 6c and the liquid driving force is generated in an arrow 14 direction by a Marangoni effect, by which the inks are fluidized and the film thickness is leveled off. The film thicknesses are thus uniformalized in each of the color element layers. The respective color element layers 6-8 are dried and cured in this state by a heating lamp 13. The specified spacing from a liquid crystal driving TFT is thereby maintained and the contrast of the liquid crystal display panel is improved.

Title: Minute displacement generator
Inventor: MORI SADAO
IPC: G05D3/12
Filed: 1986-09-16
Abstract: PURPOSE:To accurately produce necessary displacement, by detecting the displacement of a displacement producing element and the difference between a currently produced displacement quantity and necessary displacement quantity by feeding back the detected displacement to the input side of the element, and then, controlling the element so as to make the difference zero. CONSTITUTION:When a driving voltage v(t) is applied across a displacement producing device, an electrostrictive element 2 is displaced and a bolt 3 is distorted. If the displacement quantity of the element 2 is x(t), a voltage proportional to the x(t) appears at the output terminal of a strain gauge 4. When the voltage is amplified by means of an amplifier 5 and inputted to an error detector 6, an error voltage proportional to the displacement error of the electrostrictive element 2 is generated. The error voltage is integrated by an integrator 7. When such a constitution is used, a voltage which can compensate the quantity of error displacement caused by the hysteresis of the element is produced by the integrator 7. Therefore, a displacement quantity proportional to the driving voltage can be generated, when the voltage produced by the integrator 7 is added to the driving voltage of the displacement producing device 1 with an adder 8 and the summed voltage is applied across the electrostrictive element 2.

Filed: 1997-08-11
Abstract: PROBLEM TO BE SOLVED: To simplify a constitution so as to eliminate complicated work during manufacture, and reduce the used number of optical fibers so as to reduce manufacturing cost and obtain a uniform ring-shaped diffusing illumination. SOLUTION: Light guided in a casing 7 is reflected by reflection elements 10a, 10b, incident light end faces 6a, 6b formed at both ends are opposed to each other, and the light is incident in an annually formed light emitter 6. The light advancing the inside of the light emitter 6 is randomly reflected from a light reflection face 6ref formed at a bottom 8a of an annular groove 8 toward a light emitting face out formed on the side of an opening 8b, and is emitted to the outside. At this time, the light from both light incident end faces 6a, 6b is made incident so that lowering of the light quantity of the incident light from one of the light incident end faces 6a, 6b can be compensated for by incident light from the other one of the light incident end faces 6b, 6a, and uniform light can be irradiated from the light emitting faces 6out.  Further, there is no need for wiring optical fibers in the annular groove 8, thus making it possible to miniaturize and simplify the lighting system 1.
