Title: Optical head and positioning method therefor
Inventor: SAITO ATSUSHI
IPC: G11B21/10
Filed: 1992-01-23
Abstract: PURPOSE:To realize precise positioning with reduced number of components by roughly moving an optical head holding part in the tracking direction thereby roughly positioning the optical head and then slightly rotating the optical head around the center which is spaced apart the center of the optical head. CONSTITUTION:An optical head holding part 1a is moved in the tracking direction depending on rough motion thrust and the laser spot of an optical head H is roughly positioned in the vicinity of a target position. Drive coils 1b are then fed with currents for advancing by same distance in the opposite directions thus applying stress on the holding part 1a. The holding part 1a rotates slightly around a hinge part 1h depending on thus applied stress. Laser beam spot of the head H is then positioned precisely at a target position based on the displacement of the head H in the tracking direction (component) caused by the slight rotation. According to the constitution, laser beam spot of the optical head can be positioned precisely at a target position on an optical disc with reduced number of components.

Title: Thermal print head
Inventor: OBATA SHINOBU
IPC: B41J2/335
Filed: 1991-01-07
Abstract: PURPOSE:To make reduction of printing width in the direction of vertical scanning available for a thick film type thermal print head without letting printing quality decline. CONSTITUTION:A heat-generating resistance body in the width wider than the width on which a tip of a comb-teeth shaped common electrode 3 and that of individual electrode 4, also in the comb-teeth shape, are overlapped each other is formed and at the same time, a first thermal diffusion layer 7, being separate from the common electrode, is formed on an extension of the said common electrode. A second thermal diffusion layer 8 is also formed on an extension of the individual electrode, being separate from the said individual electrode. As thermal diffusion is made uniformly on both sides on each part in the longitudinal direction of the heat-generating resistance body, snaking does not occur to printing while printing width is controlled more correctly.

Title: Ink jet head
Inventor: HATTORI SHUNSUKE
IPC: B41J2/045
Filed: 1986-01-24
Abstract: PURPOSE:To increase the adhesive strength between a cylindrical pipe and a nozzle plate and prevent the outside air from penetrating in and air bubbles from collecting, by forming a tip part of the cylindrical pipe in the shape of a knife edge and firmly fitting it into a recessed part of the nozzle plate. CONSTITUTION:An end part on the nozzle plate 2 side of a cylindrical pipe 4 connected to an ink-supplying pipe 7 is formed in the shape of a knife edge, and it is fitted into a hole 9 provided in a nozzle plate 2. A base part 4a of the pipe 4 is adhered to a straight part 9b of the hole 9 by an adhesive such as an epoxy adhesive. Particularly when the length of the adherend part of the hole 9 and the pipe 4 is set to be about 1mm and the adherend area is enlarged, the adhesive strength is enhanced. Particularly, an adhesive having a low viscosity is advantageous in that it can easily penetrate into the gap between the straight part 9b and the pipe 4. Filling the gap between an arcuate part 9a and a tip part 4b with an adhesive 6 leads to a further increase in the adhesive strength. Ink jet type recording heads are arranged on a straight line inclined at an arbitrary angle theta to a main scanning direction (X-axis) at regular intervals (m) in the X-axis direction so that the pitch in a sub-scanning direction (Y-axis) becomes P.

Title: Molecular-beam apparatus for growing crystal
Inventor: BABA YASUO
IPC: H01L21/203
Filed: 1989-01-20
Abstract: PURPOSE:To enable crystal growth with high efficiency and prevent contamination of a grown crystal and deterioration in an apparatus by providing a rotating means for a disk or cylinder and a substrate holder and a molecular-beam furnace in a specific manner in an ultrahigh vacuum chamber. CONSTITUTION:Migration.enhanced.epitaxial(MEE) growth is started in a stage when a substrate attains a crystal growth temperature. Since a stabilized surface of group V atoms is exposed from a semiconductor substrate, irradiation of groups III atoms with molecular beams is started. Since the substrate is moved at a speed of revolution corresponding to the facing time of the substrate and the furnace in front of respective furnace.boats, a shutter is opened when the optional substrate is opposite the furnace of group III beams. Since a disk or cylinder is rotated at a position adjacent to the respective furnaces, the the substrate passes by the front of the furnace of group III beams after the facing time is over. Thereby, the substrate will not be irradiated with the group III beams. The next substrate adjacent to the grown substrate is moved in front of the furnace of group III beams by rotation of the disk or cylinder and irradiated with the group III beams.
