Title: Jumping control system for optical disk device
Inventor: SAKAMOTO NORIAKI
IPC: G11B7/085
Filed: 1988-09-02
Abstract: PURPOSE:To shorten a setting time after a macro jump and to speed up a track access by impressing a direct current components signal to a tracking actuator in a standby period from an acceleration pulse to a deceleration pulse. CONSTITUTION:By a control circuit, a tracking servo error signal RES and a jump trigger pulse are given to an acceleration/deceleration changeover timing circuit 12. Signal voltages corresponding to pulses P1 and P2 and a direct current components signal D0 are outputted from an acceleration signal generating circuit 13, a deceleration signal generating circuit 14 and a direct current level setting circuit 15 to receive a timing signal from the timing circuit 12, respectively. The direct current components signal D0 is supplied to a tracking actuator 5 in the period between the pulses P1 and P2. Namely, since a force is impressed by the direct current components signal D0 after the impression of the acceleration pulse P1, the swing-back of an objective after the acceleration is suppressed, and the dispersion and unstableness of a position control can be eliminated. Thus, the setting time can be shortened, and the track access can be made high-speed.

Title: Production of liquid crystal panel
Inventor: KASHIWAGI TAKAFUMI
IPC: G02F1/1333
Filed: 1989-08-28
Abstract: PURPOSE:To prevent a sealing material from being broken through by a liquid crystal before curing and to completely cure the sealing material in a short period of time by providing an adhesive agent consisting of a UV curing type resin or hot melt type resin on both surfaces of a frame-shaped film. CONSTITUTION:A plastic film 1 having a frame shape is disposed on the surface of a film substrate 3 subjected to an orientation treatment and a required amt. of the liquid crystal 4 is dropped into the frame. A film formed with transparent electrode patterns is used for the film substrate 3. After the other film substrate 3 is superposed thereon, a mask 6 to prevent the fall of UV rays onto the liquid crystal is provided. The adhesive agent is then irradiated with UV rays from both the front and rear surfaces and is thereby cured. The leaking out of the liquid crystal by breaking through the sealing material is obviated in this way even when a deviation arises in the flow of the liquid crystal and the liquid crystal comes into partial contact with the seal at the time of sticking of the substrates to each other after dropping of the liquid crystal. The adhesive agent layer is merely necessitated to be provided extremely thinly on the surface of the frame-shaped film and, therefore, the time for the irradiation with UV rays is drastically shortened.

Abstract: PURPOSE:To make it possible to eliminate paper jam easily and rapidly by providing a constitution in which a disconnection mechanism which disconnect a mechanical part for transmission of power from a motor to a platen roller through an external operation whenever necessary in the mechanical part for transmission of power. CONSTITUTION:If paper jam occurs, a push bar 32 is manually pushed through a small hole after opening a front door. Consequently, the bar 46 rotates counter-clockwise around a pin 45 to move a U-shpaed member 43 in an arrow A direction. Then this member 43 moves with a spur gear 18 resisting the recoiling force of a compression spring 34 to disengage the spur gear 17 from the other spur gear 18. This disengagement disconnects a system to transmit power from a motor 14 to a platen roller 11, so that it is possible to turn the platen roller 11 easily with the hand. Thus a jammed recording paper 10 can easily be removed.

IPC: B41J2/475
Filed: 1986-09-19
Abstract: PURPOSE:To prevent a photosensitive member from being wastefully used by operating a light shielding unit by a signal of light quantity detecting means when the light quantity of a light source decreases so as not to obtain an image of high quality to shield a light to the member. CONSTITUTION:A light ray from a light source 1 is irradiated to an original 2, and its reflected light is irradiated through a lens 3 to a photosensitive member 4. The light quantity of the light source 1 is detected through a mirror 9 by a photodetector 10, and input through an amplifier 11 to a central controller 12. When the light quantity of the source 1 is so decreased as not to obtain an image of high quality, a controller 12 drives a motor 8 through a driver 13 to project a light shielding plate 5 between the lens 3 and the member 4 by a motor gear 7 and an arm 6 with a rack, thereby stopping a copying operation. Thus, it prevents an image recording of low quality from being output, thereby effectively utilizing the member.

Filed: 1982-12-17
Abstract: PURPOSE:To guide water outward to be discharged thereby preventing the water from entering the room of a vehicle, by forming a water draining groove in the inside of a turned seal lip. CONSTITUTION:When front and rear wind panels are closed tightly, a tip section 2b and a base sectiin 5a of the seal lip 5 are made in firm contact with each other. As a staggering groove 11 is formed in the groove 10, if water is spouted downward of the center seal rubber 3a, the water can be prevented from flowing backward to enter the room of the vehicle via an opening 15. As at the forward end of the tip section 5b a ridge 16 is formed at least on the section where the staggering groove 11 is provided, and the ridge 16 is in close contact with the base section 5a, the water spouted from outside would not enter the staggering groove 11, and therefore the groove 11 would not interfere with the water backflow preventing function.
