摘要:
A flexible magnetic disk drive is disclosed which has a data transducer mounted to a pivotal support beam for movement into and out of data transfer contact with the disk. When the transducer is retracted away from the disk, the support beam butts on the top plate of the disk drive casing for the reduction of the thickness of the disk drive, that is, its dimension in a direction perpendicular to the plane of the disk. A stepper motor is provided for moving the transducer across data tracks on the disk in response to external stepping pulses from a host system and to internal stepping pulses for recalibration. The application of such stepping pulses to a stepper motor control circuit is prevented when the disk is not loaded in the disk drive, in order to avoid the movement of the support beam in sliding contact with the top plate.

An MVA type liquid crystal display panel of the present invention comprises a first substrate where a light transmission section consisting of a pixel electrode 15a, whose corner portions are chamfered, is formed at each position partitioned by scanning lines 13 and signal lines 14 that are arranged in a matrix state, in which a protruding electrode 40 extending from the pixel electrode 15a is formed between the chamfered position of the corner portion and the scanning line 13 to prevent the inclination of liquid crystal molecules due to the effect of the potential difference occurring between the scanning line and a common electrode. According to the present invention, it is possible to provide an MVA type of liquid crystal display panel having high contrast, where contrast reduction caused by the inclination of liquid crystal molecules due to the effect of the potential difference occurring between the scanning line and a common electrode is controlled, even where the liquid crystal display panel employs pixel electrodes with chamfered corner portions.

A display device includes a plurality of light emitting elements arranged in a matrix. A scan signal is made to flow into a gate signal line and a data signal is made to flow into a source signal line so that the data signal is applied to a source electrode and the scan signal is supplied to a gate electrode of a control TFT arranged at a portion where the both signal lines intersect when viewed from above. Thus, when the control TFT is turned ON, a drive TFT having a gate electrode connected to the drain electrode is turned ON, so that current is supplied from a power supply line via the source electrode and the drain electrode of the drive TFT to an organic EL element and the organic EL element emits light. A holding capacity is present between the control TFT and the drive TFT. Even when the scan signal becomes LOW level and the control TFT turns OFF, the gate potential of the drive TFT is held for a predetermined period of time by the holding capacity and the organic EL element continues to emit light.

A stereoscopic image display device 30 comprising a backlight 32, a liquid crystal display panel 36, a liquid crystal parallax barrier 44, and a spacer member 40 arranged between the liquid crystal display panel 36 and the liquid crystal parallax barrier 44, in which the spacer member 40 is made of a glass material different from that of the glass substrates 36a, 36b constituting the liquid crystal display panel 36, and the spacer member 40 is a glass substrate having a thermal expansion coefficient larger than that of the glass substrates 36a, 36b constituting the liquid crystal display panel 36. More specifically, it is preferable that the spacer member 40 consist of a soda glass substrate and that the liquid crystal display panel 36 for display be formed of non-alkali glass. With this constitution, it is possible to provide a stereoscopic image display device, which can be used as a large-sized stereoscopic image display device by means of the liquid crystal parallax barrier method, with good display quality and where due consideration has been given to the thermal expansion of the substrate caused by heat generated by the backlight, and the manufacturing method therefor.

A semitransmissive liquid crystal display panel 10 has a first substrate 11 having, formed in each of the areas demarcated by signal lines and scan lines laid in a grid-like shape thereon, a reflective portion and a transmissive portion formed by a pixel electrode 15 having a slit 17, a second substrate 19 having formed thereon a color filter 21, a common electrode 22, and ridges 23 and 41, alignment films 24 laid over the first and second substrates 11 and 19 and processed for vertical alignment, and a liquid crystal layer 25 laid between the first and second substrates 11 and 19 and showing a negative dielectric constant anisotropy. When no electric field is applied to the liquid crystal layer 25, the liquid crystal molecules are vertically aligned, and, when an electric field is applied to the liquid crystal layer 25, the liquid crystal molecules are horizontally aligned and inclined in the directions restricted by the slit 17 and the ridges 23 and 41. The slit 17 is formed in a central portion of the pixel electrode in the transmissive portion, and the ridges 23 and 41 are formed at the periphery of the pixel electrode 15 and in a central portion of the reflective portion.

An easily breakable plastic capsule according to the present invention comprises a hollow cylindrical body capable of elastic deformation. The body is packed with a fluid material. An end wall of the body is formed with a plurality of radially extending grooves. When the body is deformed elastically, the bottom walls of the grooves are broken, so that the material flows out of the body through tears in the grooves. A water filter according to the present invention comprises a casing, made of paper and coupled to a cigarette, and a filter member and the capsule arranged in the casing. The grooved end wall of the capsule is situated in close vicinity to the filter member.
